Description

Electronically detectable compound oil and filtrating equipment thereof

The present invention relates to a kind of machine oil filtrating equipment, particularly a kind of electronically detectable compound oil and filtrating equipment thereof.More particularly, this oil strainer and filtrating equipment are that a kind of environment protection type is filtered actuating device, it is used for producing Suo Lidun wave effect (Soliton waveeffect) and rotating power source, on the composite basis of fluid mechanics, Suo Lidun wave effect and fuzzy theory, by reducing the air bubble in the lubricant oil, thereby keep stable oil pressure, stop machine oil burning and consequent pollution.

Economy and environment should complement each other, and Environmental Technology is no exception.At industrial field, such structure and equipment need, it is a kind of novel filtration system that satisfies environmental protection policy and design, it not only can reduce the particle in the muffler, and by stoping machine oil burning in the internal-combustion engine also can stop the generation of carbon dioxide, by cutting the waste as much as possible, thereby save the resource and the energy.

Can no longer continuing previous the sort of filter, only to use the system of once throwing away and device be necessary, it can reduce the pollution of industrial goods, improve our living environment, save the energy, it substitutes these article of being thrown away and promotes effective utilization of industrial goods, it is widely used at industrial field in worldwide cleaning technology.

In all industrial machines and internal-combustion engine, the excessive supply of machine oil not only can produce air bubble owing to the pulsating pressure in the motor, and, because the burning of oil also can produce carbon dioxide.

Yet the present invention is a kind of device that has installed the filter of environment protection type, and it is by the generation of controlling bubble and the generation that has reduced carbon dioxide effectively, for protecting environment and then preventing that the global warming phenomenon from contributing.

Device of the present invention has reduced mechanical loss by the circulation of the machine oil in the circulatory system that promotes industrial machinery or internal-combustion engine, as friction and wear.On function, its expansion and accelerated the radius of clean-up of hydraulic press.In addition, it has also improved cooling effect, thereby has prolonged the working life of industrial machinery.

Machine oil is a kind of expendable article, and filter also is a kind of expendable article.These article are usually with just throwing away later, and this custom is existing for a long time.

Now normally used folding paper mold oil strainer owing to its structural reason, can not fully absorb and receive and keep pollutant, and when the branch road opening, pollutant flow in the motor once more, and mixes with machine oil and to pollute.

In addition, it is so big so that air bubble produces in a large number that the pressure that the bypass valve of existing apparatus is subjected to slides, thereby causes the high great amount of carbon dioxide that produces of machine oil rate of combustion.Further, filter area is structurally very little, and the cycle that machine oil changes is so short so that become a source of industrial waste product and oil pollution.Existing filter will block in the very short time lag, thereby must change.This is a kind of provisional filter, thereby has caused a large amount of waste products.

Up at present, also there is not a solution to be suggested so that abandon continually the more custom of change engine oil and filter, the scheme that internal-combustion engine need not keep in repair is proposed.

In addition, because the generation of bubble, the supply of machine oil can not be satisfied.Much less, because drive condition such as engine start, cold start-up, departure and parking cause the flip-flop of oil pressure, this is the very big load that oil pump sucks load, and this big load is reflected to rapidly in the lubrication system, and rotating speed increases in proportion.This problem does not also solve in the structure of fan-fold paper type filter.

The present invention advises a kind of guidance and direction of the filter that can increase the service life of environment protection type, and this filter is as a kind of full flow pattern filter, for the function of improving filter and prolong its life-span, only needs convert the depth filteration to by the by-passing filter method.This need improve so that it uses the long period on existing structure of filter.

The objective of the invention is to change the principle of the filter in long-term the use, it can be regenerated with the machine oil of crossing not and will throw away or be used as waste disposal with the machine oil of mistake.It also makes the not contaminated possibility that becomes of machine oil.

Therefore, the present invention proposes a kind of filter (elephant) by removing in the ecology the atomic filter of removal less than 0.02 micron toxin, it is by highdensity still undiscovered before this filter paper, and the fine particle that can filter less than sub-micron shows very high strainability.

Product of the present invention has reduced the machine oil of pollution and the amount of waste product.It does not discharge waste oil basically, has therefore improved the structure of oil strainer.In the present invention, Pascal's law and orifice flow theory comprise that Hydrodynamics Theory, Bernoulli's therem have help to the effect of oil strainer.When oil strainer was worked, the pulse of the compression of Suo Lidunbo had been accelerated the speed of filtering with an acceleration.

On the other hand, the present invention has improved the ability of catching impurity by the filter capacity that promotes degree of depth type oil strainer.

Fig. 6 is the theory diagram in the source of expression design of the present invention.

Gear oil pump that is associated with drive condition and Mechanical Driven power and the work relationship between the oil strainer always do not flow with constant oil pressure and with the circulatory system in fluid situation about flowing consistent.Therefore, meet the drive condition that drives sensitivity and require the oil pressure that keeps constant and stable, increase possibility by the optimum condition that causes eddy current rather than pressure fluid.

The present invention is a kind of device of equipping filter, it meets the flow of fluid of being derived by fuzzy theory, determine the contract drive condition of liquid of oil pressure according to the fluctuation of oil pressure and oil mass, machine run condition and flox condition, and select suitable filter according to electrical signal.

The present invention relates to a kind of oil strainer and device thereof, its purpose is to make machine oil to circulate under high speed can not run into the resistance that oil strainer causes, supply machine oil makes oil circulation in a short period of time, and prevents wearing and tearing or the damage of motor in the incipient stage rapidly.

The objective of the invention is to convert the horizontal filter method along separate routes of traditional folding paper mold to fine and close vertical depth filtration approaches.

Filter paper of the present invention is provided with macropore and aperture vertically on its level and smooth surface, a round from top to bottom from large to small, another round changes from small to big from top to bottom, several rows of hole is staggered to be arranged in parallel, and then filter paper is rolled into a roller.Up to the present, particle and dirt all are fluid is sent to the surface of filter paper with 90 ° of angles and is captured.And in the present invention, fluid is absolutely blocked, and is freely to link to each other with pulse and flow, and therefore, fluid keeps compression pulse and not diffusion.By utilizing the Suo Lidunbo theory, the performance and the condition that are suitable for fluid are selected, thereby the characteristic that definitely meets non-compressed liquid is used to drive the amount of operation, therefore, and flow faster, and the machine oil burning is controlled to greatest extent.

The present invention is constructed such that it controls the reason that produces carbon dioxide and particle effectively, does not promptly cause the generation of air bubble by machine oil is refluxed at a high speed, thereby has prevented burning, and controlled the generation of carbon dioxide and particle.

System of the present invention is the hammering pressure that produces owing to the driving operation amount in engine oil recycle system in order to eliminate, move by the control of manipulator is cooperated with the filter that is fit to, pass puzzled device (piezoelectric type) by air bubble sensor, temperature transducer and pressure and convert operation amount to electrical signal.

It is said that motor is when starting or during cold start-up, the wearing and tearing of motor account for 80%.Existing oil strainer can not be guaranteed sufficient instantaneous mobile flow owing to its structural reason.And use when of the present invention, guarantee that not only the instantaneous mobile amount of initial stage abundance is possible, and can also absorb initial hammering pressure that it also is very fast entering penetrating of high density filter paper.In the present invention, aforesaid problem can be resolved by the solenoid valve shown in Fig. 2.This part is called as inceptive filtering portion.

Filter and device thereof are controlled by the manipulation device, manipulator is selected the filter of needs according to electrical signal, in computer, calculate in the circulatory system oil pressure and because the range of function of boost (rising of pressure is because due to the increase among the RPM) resistance coefficient that causes and the decline static pressure (pressure arrives low pressure from the rising peak pressure) of change, and itself and the relation that drives operation amount are compiled into program according to fuzzy theory.

Utilize the power source of oil pressure in the circulatory system to be installed in the inside of oil strainer.Drive propeller and be installed on the live axle, by pressurization and discharging to oil pressure, more substantial oil spout can obtain.On the other hand, obtained as the driving force of the 3rd rotating power source.

This device is electronically detectable compound oil and device thereof, it has produced the effect of amplification to the cooling of oil owing to the reason of quickening, wherein, filter is as shown in Figure 2 twisted on the outer surface of inner casing by the filter paper big aperture with vertical setting, that have very high absorptivity.Its center is a cylindrical tube, resemble a paper roll, the pulse of the natural quality of absorption fluids, the flow of the machine oil that passes through is blocked by 100% ground, has the channel theory of Suo Lidun wave effect by utilization, thereby the pulse oil pressure that some is designed always keeps constant, be used for manipulator device and can make and keep Suo Lidunbo and become possibility and a mechanism with solenoid valve is installed, by controlling resistance to greatest extent, continuous structure can make the diffusion of high speed blip, and can not reduce mobile waveform.Not oil stream absolutely to be blocked and be sent to filter by resembling the prior art, but improve filter capacity by the compression pulse that absorbs strong pulse in the oil stream, and produce the Suo Lidun wave effect continuously, the biggest ground control structure resistance promotes to flow, and can not eliminate pressure waveform in the circulatory system, thereby cause more substantial oil stream flow, from then on pollutant passes through.

Know that stop the burning of I. C. engine oil, carbon monoxide can reduce.This by the generation of control air bubble, can stop the burning of oil owing to the generation of air bubble in the circulatory system.

The present invention has done rapid variation to the principle of filter and branch road, this is based on and has utilized the Suo Lidunbo control technique as a development theory, and oilhydraulic engineering theory, Pascal's law, Bernoulli's therem, orifice flow principle and Suo Lidun wave effect have been used, its with the mobile fusion of oil strainer at oilhydraulic engineering among the theoretical and mechanically actuated, make the physical property and the mechanically actuated of fluid produce the Suo Lidun wave effect, also be in order to solve difficult problem, thereby guarantee the flow of the abundance of oil stream in the depth filtration approaches by deep bed filter.

Electronically detectable compound oil and device thereof, it can make oil stream qualitative, quantitative ground flow and stop the burning of machine oil, in the circulatory system of motor, do not produce air bubble, first, second branching unit and manipulation type device by machinery keep waveform, have adopted the basic science theory in oil strainer.

Because the fluid in the engine oil recycle system of internal-combustion engine is non-compression, particularly between gear pump and the filter, irregular hammering and the pressure jumpy of moment often takes place, this is the principal element that produces air bubble, therefore, it is necessary eliminating this physical impact.

In order to keep constant oil pressure, thereby, be provided with one or more sensor devices, the instantaneous hammering pressure that unexpected variation produced and the shock wave kinetic pressure that are produced in flowing can be captured sensitively, by piezoelectric effect pressure transducer is connected with the air bubble sensor, rapid response is become electrical signal with the physical impact of keeping quick flow pulses, just can control the generation of air bubble well.

On the other hand, by keeping the Suo Lidun wave reflection continuously oil stream is not disperseed, by keeping of shearing, oil is held its inertial force and does not have to the static state of stablizing oil pressure, under high speed, select a suitable filter these filters that link to each other from flowing with each fluid, because the fixed end of same device has promoted the continuity (Suo Lidun wave effect) of reflected wave greatly, solenoid valve by relay and manipulator device etc., filter is very sensitive to the dynamic rising oil pressure and the quiet oil pressure that descends, it is used to react rapidly, therefore, can guarantee that oil stream qualitative, quantitative ground flows, in institute is free, can not produce the gap in the oil stream.Therefore, the structure of electronically detectable compound oil can obtain stable oil pressure and stable oil stream flow.

The part that satisfies very much its resistance that links to each other with rotatingshaft in the engine oil recycle system, the fluid of thickness flow to be divided into dynamic rising oil pressure and the form of the quiet oil pressure that descends forms waveform.This is the flowing of fluid with flow characteristic.In order to keep the compression pulse of Suo Lidunbo, it is a very lasting indiffusible ripple, when the flow of machine oil increases, dynamically rising oil pressure and resistance value are found and calculate, and in the waveform of liquid and pressure each flow of shown oil stream, the drop-out value of the quiet oil pressure of decline type compares, and calculates according to fuzzy theory, is fit to the computer program of the impulse oil pressure of optimum flow with the function establishment.(owing to the reason of excessive mobile formation air bubble generation.In addition, this also is the obstacle that oil film forms).

The present invention is such device, wherein You flow and the continuity between the oil pressure are adjusted to filtercondition (oil pressure is used the condition of filter), but it needs the filter of a plurality of phase co-conversions, and replacement conversion operations wherein can produce the various fluctuation pressures of bamboo according to the flow of organic oil and instruct.According to fuzzy/pure and fresh theoretical suitable operational condition of setting up, select filter selectively, the electrical signal instruction that is fit to is separated from drive unit, the Pulse wave that can not destroy that drive unit will be suitable for fluid converts compression pulse to, and make its last very long, so that utilize the Suo Lidun wave effect.

Do not produce air bubble for oily qualitative, quantitative ground is flowed to continue the Suo Lidun effect, fixed end is provided with by structure, and compression pulse is produced to continue the generation of best Suo Lidun wave effect in the fuzzy theory.General description the form of various fluctuations.

As a kind of method of controlling the air bubble generation, manipulator device, relay and solenoid valve are inserted into, under the instruction of the computer program that designs according to fuzzy theory, according to the function relation electrical signal, a filter that needs is selected from a lot of filters continuously under high speed.Therefore, this device is an electronically detectable compound oil and device thereof, and it makes and stops the machine oil burning and reduce CO, CO ₂, the Suo Lidun waveform is not spread not disturbed yet.

When engine start, strainability and resistance have mutual exclusive each other physical principles.Instantaneous machine oil short supply is the principal element that causes engine scuffing at this moment, and this just need be based on the structure of filter of variety of issue in the solution circulatory system of following new ideas.The structure of accelerating to filter is two size devices.At first, the penetrating power that machine oil carries out in the filter screen has been reinforced, and the rapid circulation that elementary (first) branching unit can promote the fluid next from the outside greatly is installed.

In addition, such phenomenon is drawn in the operation that is fit to, and promptly the substantial slippage of the guiding valve of elementary branching unit is matched with internal drag, and it is owing to the backflow from the ejection of main flow hole, so this can be used as second operation unit.Therefore, this device is an electronically detectable compound oil and device thereof, and along with the quickening of engine speed, temperature raises, an available marmem, and it can increase and reduce the tension force of spring sensitively according to use.

Electronically detectable compound oil and device thereof are arranged to stablize oil pressure, even the amount of the machine oil that is filtered is passed through passive mechanical function under very little pressure, can fully flow out and be operated sensitively, according to oil pressure baffle plate is installed, it flows at an angle of 90 with oil, this is in order to keep stable fluctuation pressure by a plurality of or multistage filter, to arrive the high speed rotating change suddenly and make sensitive reaction from low speed rotation portion.

Electronically detectable compound oil and device thereof, live axle is housed, it doubles oil speed and capable and consistent with oily levelling as propulsion device, and the amount of the oil stream that its rotating inertia force increase that utilizes oil pressure to produce is ejected produces rotary driving force by oil pressure and can equip mechanical driver unit.

That is to say to the present invention proposes a kind of electronically detectable compound oil, wherein, this filter has the filter that is arranged between inner casing and the shell; Be positioned at the cap with machine oil inlet of its upper end and have the basic valve of oil nozzle, it is characterized in that, this filter also has and is formed between described filter and the described inner casing and the bypass passage that links to each other with the machine oil inlet; First branching unit, it has the first branch road hole of a plurality of bottoms that are arranged on described inner casing with radial manner and the device in the described first branch road hole of opening/closing; Second branching unit, it has the second branch road hole on a plurality of tops that are arranged on described inner casing with radial manner and the device in the described second branch road hole of opening/closing.

Described first branching unit has a pair of guiding valve, and this guiding valve and last lower spring are arranged on the inner edge of described inner casing, and is in contact with one another the described first branch road hole of opening/closing by guiding valve; Filter screen is relative with the described first branch road hole, and regulates the described bypass passage that oily stream enters into the inside of shell.

Described second branching unit has the spout that is drilled with in the upper and lower part of described basic valve; Flow into the described second branch road hole and the described guiding valve of going up spout of opening/closing by machine oil.

This filter is provided with baffle plate in the bottom of described basic valve, and what the oil of the spout of the bottom of described first branch road hole of its restricted passage and described filter flowed flows.

Power source with the inside that is installed in described inner casing, and according to the mobile acquisition rotational power of oil stream.

Described power source is provided with propulsion device, and this propulsion device is installed between described first branching unit and the described basic valve, and live axle links to each other with described angle of rake lower end and can be rotated to support on the bottom of described shell, and this lower end is stretched out by described shell.

Described filter is rolled into paper bowl shape by filter paper, has big aperture on this filter paper.

The invention allows for a kind of electronic detection type composite filtering equipment, it is characterized in that this filtrating equipment comprises: sensor device, the rotating speed of the temperature of its sensing oil, air bubble and pressure and motor; Microcomputer, it imports the data of described sensor device and the pulsation supercharging and the decline type static pressure of oil; Manipulator device, it has a plurality of solenoid valves and a plurality of relay, and this relay is according to the described solenoid valve of output order opening/closing of described microcomputer; A plurality of filters, it is configured to relative with described solenoid valve.

About the speed of oil stream among Fig. 2, when machine oil suffered part resistance during by filter 50, it is downward that machine oil promotes guiding valve 32 through the branch road hole 31 on the inner casing 12.At this moment, to promote guiding valve 32 downward owing to stressed, and the speed of oil stream is changed into pressure.Simultaneously, mobilization force is by the cross section in the second branch road hole 31, and oily rheology is slow, and makes oil stream reduce by the flow of branch road.On the other hand, the pressure that increases by supercharging makes pressure arrive filter 50 also at any time from wherein passing through.The pressure that is added on the guiding valve 32 in the inside of the filter 10 of deadend is added on the whole wall of container equably, and this pressure is identical with the pressure of increase.(Pascal's law)

Oil stream is by sectional area, and the sectional area of the upper end of filter 50 is tens times of sectional area in the branch road hole 33 of guiding valve 32, and the stream that oils on the surface in this branch road hole passes through.So though be subjected to some resistances (its resistance coefficient is 0.3) of filter 50, the flow of oil stream remains bigger, so, become big from the flow of the oil of main oil inlet ejection.

Along with the quickening of flow velocity, the second branch road hole 31 of inner casing 12 and the same pressure number of times at a crossing 33 also become many, and therefore, guiding valve 32 is opened a bit, and the flow of oil also is restricted.

Under certain conditions, pressure and oily flow are directly proportional, so the flow of oil increases along with being pressurized to high pressure.Yet at main oil inlet 15, when on high-tension side pressure during to low voltage side, oil mass is equivalent to square (Q=V of flow velocity ²), so flow increases greatly.

And then, along with flow constantly reduces, in the bottom surface of filter 50, high pressure becomes speed, and therefore, depression effect (siphon power) is produced, and the speed (siphon speed) of oil stream accelerates.In other words, oil is vomited and is recycled from the main oil outlet 18 of the bottom of filter 50.

Utilize oil pressure, by means of mechanical transmission mechanism, fluid is passed through vertically in highdensity filter, this is based on the basic science theory of having utilized oilhydraulic engineering.

The thin paper element is that the sectional area of the whole circumference of filter is long-pending tens times big of the entire cross section of bypass passage 13, if resistance coefficient 0.3 is deducted on the cross section of oil stream, oily flow in the bottom of filter 50 just becomes very big, and the pressure of main oil outlet 18 just becomes very high.

According to the orifice flow theory, the flow that flows to the machine oil of low voltage side from the high pressure side is square (V of speed ²), so as shown in Figure 4, oil is ejected under condition of high voltage continuously, and flow out rapidly from main jet hole 18 and a plurality of spray orifice 18 ', along with oil with V ²Speed when flowing to the side of basic valve 16, pressure is reduced, and is produced in the bottom pressure relief effect of thin paper element (filter) 50.Then, filter is as the rapid absorption machine oil of suction, and machine oil passes through filter at an easy rate, thereby makes machine oil greater amount ground become possibility by filter.This part is called as phase III master filtering area.

On the other hand, as shown in Figure 5, the internal pressure of guiding valve 32 and basic valve 16 has increased the number of times of dynamic pressure by causing operational condition (uniform pressure), guiding valve 32 is to be operated with the speed of quickening, so, the stroke radius that promptly claims piston that moves up and down of guiding valve 32 diminishes, and it is inversely proportional to distance, and oil is little from the quantitative change that basic valve 16 flows out like this.This part is called piston type second stage high-rate fitration district.In order to eliminate inertial pressure, impartial pressure is formed with acceleration causes guiding valve 32 and branch road opening 34 release sensitively, and the frequency that moves up and down of guiding valve 32 is accelerated.Therefore, press the power (is to add on one point to go up according to Pascal's law power) of guiding valve 32 to increase pressure, this pressure is suitable with the lip-deep pressure that is added to filter 50, and the pressurized condition is all forming at any time.

Under certain condition, the oil pressure total amount is directly proportional with the flow of oil, and by the drive condition in the bypass passage 13, high hammering pressure produces continuously, and bypass passage 13 is paths of oil flow, and the spraying high pressure produces in main injection jet 18.In other words, because oil flows to a crossing 33 (low voltage side) of guiding valve 32, the volume production of the oil of (main injection jet 18) ejection has been given birth to depression effect (siphon power) from the high pressure side, so, up to the present, guarantee that oil mass in depth by highdensity filter 50 (thin paper element), is considered to the problem of a difficulty, but, make oil mass by becoming possibility by having solved this problem now.

Therefore, what the opening of piston type guiding valve 32 can not do along with the rising of oil pressure.Because all press, the moving range and the time of guiding valve 32 are inversely proportional to, the displacement distance of reciprocable valve shortens, thereby by cycle time, impartial pressure is produced.

Like this, the range of opening of the guiding valve 32 that is directly proportional with the increase of rotating speed diminishes gradually and becomes more frequent on the contrary, and it is under the vibration condition work and can open with reverse.

When causing that when sudden startup or owing to the drive condition of internal-combustion engine rotating speed increases (idle running), oil stream is generation hammering pressure continuously.This is the principal element that produces air bubble, and eddy current also produces thus, prevents that it from being necessary.

By dispersion and diffusion that the baffle plate 60 that inserts stops oil to flow, oily stream can be adjusted.In addition, the guiding valve 22,23 of elementary branching unit 20 links to each other with bypass passage 13 and is provided with, and when continuous hammering pressure produced in the starting stage, it can be adjusted by opening these guiding valves 22,23 rapidly, therefore, it can be cancelled the oil pressure that reaches stable by eliminating dynamic pressure.This is called as the phase I filtering area.

The oil mass of the main injection jet 18 of the bottom by being positioned at filter 50 and oil pressure promote guiding valve 22,23, the oil pressure and the resistance that are added on the circumferential area on every side become: Q+Q '+X 〉=Y, therefore, guiding valve 22,23 is pushed and can not keeps balance, the oil spout direction is regulated in advance between two shape memory alloy springs 24,25 and guiding valve by a coefficient, unclamp its function of its opening/close.

On the other hand, by regulate shape memory alloy spring 36 under general operating conditions, the oil temperature descends, so baffle plate can be operated at an easy rate, and eliminate early stage idle running and hammering pressure, thereby, promptly promote machine oil to be penetrated in the highdensity filter 50.

Therefore, the operating range of the guiding valve 32 of second branching unit 30 is second stage high-rate fitration districts.When automobile moves with fixing rotating speed, move by the operation of guiding valve 22,23 or in constant rotational speed and high speed rotating speed, pulsating pressure just can not produce.

Guiding valve 22,23 has reduced engine scuffing, its not only since when engine start or during cold starting because the generation of hammering pressure causes, but also cause owing to continuous oil starvation makes the rotating speed increase.

When engine start, be directly proportional with increasing continuously of rotating speed, because the structural different pressures of the oil strainer in using now make the oil of ejection produce a large amount of air bubbles continuously, thereby oily circuit quality is not hoped.

Therefore, when high pressure or continuous hammering pressure generation the time, velocity transducer 71, temperature transducer 72, air bubble sensor 73 and pressure transducer 74 detect it continuously, and by machinery or electrical control manipulation apparatus 90, with to a plurality of filters 10,10 ', 10 " carry out suitable operation.

Microcomputer 80 purposes are by the input filter structure and the impulse ratio of the oil pressure in flowing is guaranteed oily flow, wherein, oil stream has the Suo Lidun wave effect, prepare a fuzzy operation program, make the loop cycle of oil stream, its function by the amount of the pulsation of the oil in the pressure is determined according to mechanical property the operating temperature of hydro pulse, oil mass and drive condition, high speed circulation in the oil stream lubrication system does not have obstacle that air bubble is produced.

Be equipped with a plurality of solenoid valves 91,91 ', 91 on the manipulator device 90 ", these valves are directly to change valve, high speed operation under from the instruction of microcomputer 80.These solenoid valves 91,91 ', 91 " handle a plurality of filters 10,10 ', 10 " so that its react rapidly and work.Each filter all provides best drive condition for having removed the oil circulation that air bubble has a stable oil pressure pulse, according to the pulsation in operating conditions and the oil stream, qualitative, quantitative ground supply in lubrication system, utilize shape memory alloy spring 24,25, change the tension force of filtration resistance and guiding valve 22,23.

In order to obtain power source 40, the high speed jet that flows out in main injection jet 18 by filter 50 has been utilized.In other words, the machine oil by main injection jet 18 sprays under injection conditions, and the rotation by live axle and coupled propulsion device 41 has obtained power source.

Known motor loss 80% occur in its when starting.Therefore, utilize the centrifugal force of propulsion device 41 to make oil stream can not run into the oil strainer resistance and always under high speed circulation be to thirst for most.

When rotating speed increases because the obstruction or the air bubble of filter, the amount of the machine oil that from oil pump, sprays be not resemble hope be supplied.For this reason, in the structure of motor, the roller of filter changed that its function is more preferably is necessary.

Therefore, the filter in the circulatory system should be the device of such circulatory system, and it can be guided out the mechanically actuated that is fit to that can make rapid reaction, with the circulation oil pressure corresponding to the oil that sprays from oil pump at any time.

Can think that optimal method is, guiding valve 22,23 is in depth installed, the oily pulse of flowing of purpose guiding for structural acceleration cycle, with in order to improve the penetration rate that oil flows into high density in-depth filtration body 50, when sudden startup, by absorbing the hammering pulse that is produced continuously apace, make oil flow back to.This is the phase I filtering area.

In oil strainer 10, the cycle of motion of the equalization pressure by accelerating guiding valve 22,23, be provided with the import that enters into second stage high-rate fitration district, simultaneously, stop the slip of guiding valve 32, more sufficient oil mass can be guaranteed, by stopping hammering pressure, stoping oil stream diffusion (eddy current) or oil stream vibration damping, can promote filter capacity.

The reaction of the operation of motor has been promoted, so that the improvement of its mechanical property that links to each other with filter fast is consistent.

In the notion of so far filtration, during best in principle filtering effect, the amount of the oil that is filtered and filtration resistance are reciprocal, at first to guarantee the oily flow of an abundance.Therefore, the present invention changes towards the principle of the speed of paying attention to oil stream.

So that suitably duplicate the variation of the oil temperature of motor, oil strainer is no exception as using multigrade engine oil.Promote the mechanism of filter capacity to need by a control valve unit, this control valve unit is adjusted oil pressure in the multistage, thereby oily stream can suitably duplicate instant oil pressure intensity.

Because might stop the energy loss that resistance causes and remove the root of the generation air bubble that the diffusion owing to oil pressure causes, oily stream is stable.

Used before this oil strainer constitutes like this, by throwing open/close the pollutant that bypass valve captures because its resistance may mix the side that comes back to motor.

In the present invention, if the race of engine or link to each other and sudden startup when two motions, the relative together high hydraulic operation of motion (this is the phase I filtering area) of guiding valve 32 beginnings and amount by opening the filter oil that guiding valve 22,23 causes fully.By keep at any time in the pulse and second branching unit 30 pulsation alternately, in the pulsation of oil stream and before being weakened not by diffusion, do not absorb the energy of the surge movement of first branching unit 20 immediately, above-mentioned this operation can make oily stream have continuous Suo Lidun wave effect.

Oil circulation in the oil strainer is subjected to pressure, oily flow velocity degree and the effect of drive condition and the influencing each other of cause that resistance is exerted pressure.A factor that produces air bubble with various forms is not only in the interference of eddy current to flowing, and, the loss of pressure also occurs and stopped filtering function, thereby, press for the flow that guarantees machine oil.

The machine oil chamber that accords with the filter 10 of orifice flow theory has been set up, and the different pressure of guiding valve 22,23 is reduced to be tending towards uniform pressure by sliding immediately in the shortest as far as possible time.

Guiding valve 22,23 is opened by being divided into two-part under the pressure externally, and the load of the spring 24,25 by its two ends and balance.These guiding valves are owing to the imbalance of the drag area in the drag area of oil inlet 15 and the first branch road hole is slided, thereby pressure is applied to the pin-and-hole 62 of baffle plate 60 so that immediate operation baffle plate 62.

The shape that resembles Venturi tube is provided so that the speed of the oil stream of the dynamic pressure that quickening produces with respect to the opening/closing owing to guiding valve 22,23.Owing to collide and disequilibrium with circle groove Q, Q ', this circle groove diminishes the resistance surface of the inside of the inner casing 12 that described guiding valve 22,23 is housed from the forced draught of main injection jet 18.By the oil pressure resistance, guiding valve 22,23 makes oily stream be applied in a motion backward.

Oil strainer of the present invention has the double system valve arrangement, all the other with self or duplicate an elastic composite filtrating equipment, by a passive step is set the change oil stream from the unexpected forced draught that causes to the high speed rotating district in district that slowly runs from oil pump is reacted immediately, this rotation is with respect to the pulsation of the blip by being maintained fixed end and the rotating speed of keeping all the time, it is in order to obtain optimal Suo Lidun wave effect, and it does not have diffusion by the fluctuation waveform at all very narrow restriction inner control oil streams constantly.

Fig. 2 to 5 relates to filter 10 of the present invention.This filter is provided with filter 50 between inner casing 12 and shell 11.In the upper end of filter cap with oil inlet 15 and the basic valve 16 with oil nozzle 17 are set.

The present invention proposes the environment protection type filter that is different from traditional concept that is intended to reduce cost and reduces consumption.It does not need repairing and has prolonged working life.It does not resemble industrial waste product and the waste oil is waste product.It is indispensable to improving environment.Mechanical function of the present invention is always not corresponding with the manual operation with intelligence with operation.

Particularly in the circulatory system, because the uniqueness that flows motion, this stream of liquid can not mix.

Conceptive based on the filtration device structure of three kinds of sizes that are equiped with coordinating body, according to fuzzy theory, recovery is flowed for the Suo Lidun stream of pulses and is kept its continuity, and by machine, electronic control device and oilhydraulic engineering, used existing filter has been done to change completely before the present invention thus.This is a kind of filter that environmental protection has practical application effect that is beneficial to, and it has prolonged the cycle life of replacing parts.Technological know-how and environment facies harmony, environmental protection just can be reinforced, and therefore, its function can be by harmony.

The present invention keeps very long cycle life and does not produce refuse, and its real price is economical and do not produce waste oil.

Reducing the mechanism of machine oil in motor is worked is for a long time just illustrated for the first time up to the present invention.The existing now root (root of befouling environment) that may stop the machine oil burning and produce carbon monoxide, waste gas and hydrocarbon.

Make in the Life cycle of the weak point of the restricted little filter table area of the filter that uses now be necessary completely or partially to revise Korea S, Japan is beneficial to environmental protection about the standard of oil strainer.

In the filtration principle of passing through forced draught of traditional approach, when branch road was opened or closed, the pollutant that is filtered mixed with machine oil in motor again, thereby machine oil is contaminated once more.Yet the present invention has changed this structural contractor in the existing filter fully.

The present invention can guarantee machine oil quantitatively.It can be changed into qualitative, quantitative ground with flowing rapidly of machine oil and flow, and this is because the present invention can remove or control the main cause that produces air bubble in fact.

This can be by latest developments Coriolis-type liquid stream table (Corioli ' s flow meter) be confirmed, this table can be measured the liquid stream of qualitative, quantitative.

Do not resemble existing filter, the present invention does not use by forced draught being added to the method for forcing separate substance on the filter screen, but remove air bubble by filter and filtrating equipment thereof, its structure can make it have stable stream of pulses by keeping continuous compression pulse.

In order to obtain correct, the suitable flow in the operation that drives motor, the present invention is configured to keep fluctuating and continuous liquid stream pulse by the adjustment of finishing according to program.The present invention is such device, it uses a plurality of filters, transmit the specific fuzzy program (relation function) of oil stream and the operation factors that Suo Lidun is fluctuateed, under the instruction of described control of microcomputer program, change it into electrical signal and deliver to manipulator device by the I.C. relay, make a corresponding to supply system of the operational condition with all this occasions, control is suitable for flowing of liquid, the operation of its filter in the circulatory system is moved discretely, and it has the mechanically operated amount that links to each other with supply system by suitably controlling.

The means that superparticle and pollutant are carried in the mobile conduct that the Suo Lidun wave effect does not produce air bubble and one group of air bubble are practically impossible.Therefore, flowing of air bubble can not be as the means of carrying pollutant.The surface tension of air bubble has the performance of the thing that decontaminates, and therefore, pollutant can not be placed at before arriving filter on the metal and cam and oil extraction fan in in-engine each lubrication system.

At last, when conventional filter is considered according to quantum theory, the fluctuation of particle can not be formed and the conduct means that particle is carried in conduct by producing one group of air bubble, because the generation of air bubble, in the fluctuation diffusion, can cause the loss of movable energy, therefore, pollutant spread before arriving oil strainer and is attached on each parts of motor.

On the other hand, because the less filter table area of traditional oil strainer, and the amount that absorbs small-particle is restricted, thereby it is not an effective oil strainer.

Yet the present invention is a novel environment protection type filter, and it controls the generation of air bubble by the fusion of oil strainer and control electronics.It has set up the direction of oil strainer in the world for the first time according to the oilhydraulic engineering theory.The present invention has proposed the filtration of thirsting for as the filter of highi degree of accuracy and cleaning, also is a kind of semipermanent useful invention.
