Abstract
The invention discloses a self-adaptive control method for a self-cooling pump. A two-position two-way electromagnetic valve is mounted on a pump body. An inlet of the electromagnetic valve communicates with a main pump outlet, and an outlet of the electromagnetic valve communicates with a cooling flow channel. The electromagnetic valve is in an off state normally under the action of pretightening force of a spring, and the self-cooling function is turned off at the moment. When a measured value of a temperature sensor mounted in a main heating zone exceeds a set value, a signal is sent to an electromagnet so as to drive the electromagnetic valve to work in an on state, and the self-cooling function is turned on at the moment. A variable orifice formed in the rear portion of the cooling flow channel achieves the function of ensuring the system stability.
Description
Technical field
The present invention relates to the technical field of pump, be particularly directed to the self-adaptation control method from cooling pump.
Background technology
Pump is industrially a kind of common tool of production, in mine, oil field, electric power, the field such as heat treatment
All it is widely used.Need in some scenarios pump work under absolute rating, as big rotating speed, strong load,
High ambient temperature, this proposes the highest requirement to the self-radiating of pump.Based on this requirement, patent
CN102086889 proposes " automatic cooling type sewage pump ", and patent CN103573713 proposes " a kind of high
Temperature is from cooling down hot water circulating pump ".They are all to use delivery side of pump fluid to cool down pump housing heating region,
It is achieved thereby that the most external cooling fluid cools down, reach the purpose of energy-saving safety.
But, pump was not all operated under harsh parameter in all times, also avoided the need in all times
All carry out from cooling down.A kind of self-adaptation control method from cooling pump is designed so that exist from cooling pump based on this
Start the when of necessary from cooling, it is not necessary to when close from cooling, thus realize further energy-saving ring
Protect.
Still further aspect, uses the fluid of pump discharge as cooling medium, needs to contemplate mouth pressure.If
Outlet pressure is the highest relative to inlet pressure so that the flow from outlet return to entrance is excessive, is easily caused and is
System instability.Therefore after coolant flow channel, install variable orifice additional, it is used for ensureing the steady Effec-tive Function of system.
Summary of the invention
In order to improve the work efficiency from cooling pump, improve its adaptation ability to different operating modes, design one
From the self-adaptation control method of cooling pump.
The technical scheme is that, pump is installed a detachable 2/2-way solenoid directional control valve.Electromagnetism
Valve one end connects delivery side of pump, and the other end connects the coolant flow channel on pump.In first position of electromagnetic valve makes
Portion's runner is off, and delivery side of pump fluid fully enters working region.Second position of electromagnetic valve
Making inner flow passage in the conduction state, delivery side of pump fluid section enters coolant flow channel, and is eventually returned to pump
Entrance.Control electromagnetic valve break-make position parameter be initial tension of spring and electromagnetism ferreous.Wherein electromagnetism is ferreous
Apply to control by the temperature sensor being arranged on pump main heating region with release.
Use the present invention design self-adaptation control method from cooling pump, it is possible to according to the main hot zone of the pump housing
The temperature in territory is adjusted from cooling: pass through housing heating region temperature exceedes a certain setting value when
Electromagnetism ferreous unlatching self-cooling function, closes self-cooling function in other cases.Thus avoid and sending out
Still there is cooling fluid to be back to the power wastage of main pump inlet from main pump outlet when heat is little, thus ensureing
Whole abilities of pump are played as far as possible to effective working region on the premise of safe operation.
Opening from cooling when, the variable orifice being arranged on coolant flow channel rear end is steady for adjusting system
Qualitative, ensureing that the fluid that main pump exports while cooling effect working region maximizes.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the present invention.
Detailed description of the invention
Have as depicted adaptive control function from cooling pump, easily heating on the housing of pump 1
Region is disposed with the coolant flow channel 4 of sufficient length, and easily the region surface of heating is disposed with temperature sensor 5.
The 2/2-way solenoid directional control valve 3 being arranged on pump 1, entrance connects with the outlet branches of pumping main body 2, goes out
Mouth connects with one end of coolant flow channel 4.The other end of coolant flow channel 4 is after a variable orifice 6
It is connected with the entrance of pump 1.
Initial tension of spring on 2/2-way solenoid directional control valve 3 makes the original state of its inner flow passage be off
State, now whole flows of pumping main body 2 enter working region 7.When temperature sensor 5 in pump case
Can trigger Electromagnetic Control when measured value exceedes a certain setting value, electromagnetism is ferreous pushes reversal valve 3 to conducting state.
Now, the partial discharge of pumping main body 2 can enter coolant flow channel to heating region cooling.Although consuming one
It is partially into the flow of working region 7, but is necessary for ensureing the safe handling of pump.Enter cooling
The fluid of runner adjusts uninterrupted by variable orifice 6, to avoid when outlet is relative to inlet pressure mistake
Time big, issuable system is unstable, also avoids pump discharge to be too much diverted on coolant flow channel simultaneously.
Claims (2)
1. from the self-adaptation control method of cooling pump, it is characterised in that: on the housing of pump, there are one two two
Electric change valve 3, the entrance of reversal valve 3 connects with the outlet branches of pumping main body 2, going out of reversal valve 3
Mouth connects with one end of coolant flow channel 4, and the other end of coolant flow channel 4 is communicated to main by variable orifice 6
Pump intake, the power of control reversal valve 3 position comes from initial tension of spring and electromagnetism is ferreous, ferreous the executing of electromagnetism
Add temperature sensor 5 existence arranged with release with the region surface of easily heating on pump to associate.
2. according to the self-adaptation control method described in claim 1, it is characterised in that: reversal valve 3 initial
State is closed mode, and pumping main body 2 exports whole fluid and enters working region, when heating region on pump
After temperature sensor 5 exceedes preset value, reversal valve 3 can be on position under electric magnet power effect, this
Time pumping main body 2 outlet fluid some enter coolant flow channel 4, cooling fluid eventually through variable restrictor
Hole 6 returns to main pump inlet.
