The novel centrifugal engine oil-gas separator has the advantages of adopting the pointcut of improving the separating rotation speed of the centrifugal engine oil-gas separator, improving the separating effect of an automobile engine crankcase ventilation system, adopting an engine lubricating system main oil duct as a power source, and being suitable for most automobile diesel engines.
Description
Technical field
The utility model relates to a kind of deaerator, especially a kind of novel centrifugal type oil-gas separating device for engine.
Background technique
Deaerator is most important part in vehicle engine crankcase ventilating system.Crankcase mixed gas is by after deaerator, and machine oil is separated from mixed gas, gets back to oil sump, and comparatively clean gas enters firing chamber and again burns after the separation of deaerator, reaches the energy-conservation effect with reducing discharge.At present the form of deaerator has form to mainly contain: mazy type, vortex type, filer element type, centrifugal etc., also have electrostatic deaerator in development etc. in addition.Deaerator has different structural type at present, and the power resources of separation are also not quite similar.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides one can improve vehicle engine crankcase ventilating system oil gas separation, reaches the novel centrifugal type oil-gas separating device for engine of the effect that improves motor emission performance.
The utility model solves the technological scheme that its technical problem adopts: this novel centrifugal type oil-gas separating device for engine, comprise driving mechanism, separating mechanism, driving mechanism comprises the impeller casing with filler opening and oil outlet, in impeller casing, be provided with impeller, impeller is connected with gearwheel by coupling shaft one, gearwheel matches with small gear, small gear is connected with the rotor body in separating mechanism by coupling shaft two, rotor body is provided with suction port in the middle of bottom, bottom outside is provided with return opening, and upper outer is provided with air outlet.
As preferably, in described rotor body, be provided with filter screen, can further be conducive to the separation of machine oil oil droplet in mixed gas.
As preferably, described rotor body and suction port joint are provided with rotor seal ring, prevent that oil gas from revealing in this place.
This oil-gas separating device of engine, its power source is taken from engine lubrication system main oil gallery.In the time of engine operation, utilize motor main oil gallery engine oil pressure, drives impeller high speed rotating, by gear drive separating mechanism, gear transmission can improve the rotating speed of separating mechanism, thereby reaches the object of further raising separating effect simultaneously.Separating mechanism, in the time of high speed rotating, utilizes centrifugal principle, the machine oil in the mixed gas of the crankcase that bleeds is separated, and be recovered to oil sump.Mixed gas after separated oil imports engine aspirating system, and gasoline wherein and other inflammable matters are recycled, and finally reaches the object that improves engine energy-saving and environmental-protecting performance.
The effect of this novel practical is: separate rotating speed as point of penetration to improve centrifugal oil-air separator, improve the separating effect of vehicle engine crankcase ventilating system, using engine lubrication system main oil gallery is power source, is applicable to most diesel engine for automobile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals: gearwheel 1, coupling shaft 1, oil outlet 3, impeller casing 4, impeller 5, filler opening 6, small gear 7, coupling shaft 28, air outlet 9, filter screen 10, rotor body 11, rotor seal ring 12, suction port 13, return opening 14.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: as Fig. 1, a kind of novel centrifugal type oil-gas separating device for engine, comprise driving mechanism, separating mechanism, driving mechanism comprises the impeller casing 4 with filler opening 6 and oil outlet 3, in impeller casing 4, be provided with impeller 5, impeller 5 is connected with gearwheel 1 by coupling shaft 1, gearwheel 1 matches with small gear 7, small gear 7 is connected with the rotor body 11 in separating mechanism by coupling shaft 28, rotor body is provided with suction port 13 in the middle of 11 bottoms, bottom outside is provided with return opening 14, and upper outer is provided with air outlet 9.In rotor body 11, be provided with filter screen 10, rotor body 11 is provided with rotor seal ring 12 with suction port 13 joints.
When engine operation, machine oil main oil gallery pressure increases rapidly, can reach 0.25Mpa～0.50Mpa, and diesel engine maximum can reach 1MPa, and the pressure oil that is introduced into impeller 5 enters from filler opening 6, and under the effect of pressure energy and kinetic energy, drives impeller 5 is rotated.Impeller 5 drives gearwheel 1 to rotate, and gearwheel 1 drives small gear 7 to rotate, and the speed(-)up effect of large small gear further increases rotating speed, provides possibility for improving the separating effect of separating mechanism.
Under the drive of small gear 7, rotor body 11 High Rotation Speeds, the mixed gas of inputting from suction port 13 is with filter screen 10 high speed rotating in rotor body 11.Now, in mixed gas, machine oil oil droplet is because density is large, and the centrifugal force being subject to is also larger.So machine oil oil droplet is thrown near the peripheral inwall of rotor body 11, and flows out to engine sump tank by return opening 14, machine oil is recovered utilization.Meanwhile, the mixed gas (having separated machine oil oil droplet) that centrifugal force is less is up along the middle part of rotor body 11, exports from air outlet 9.The existence of this device transfer daughter 11 Inner filter nets 10 is also further conducive to the separation of machine oil oil droplet in mixed gas.
The mixed gas of exporting from air outlet 9 is imported into the gas handling system of motor car engine again, is recycled like this from bleed petrol and diesel oil and the intermediate combustion product thereof of crankcase of piston ring periphery, has reached energy-conservation and double effects environmental protection.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
