Description
Technical field
The present invention relates to a kind of labyrinth type oil-gas separation chamber, be specifically related to a kind of labyrinth type oil-gas separation chamber installing turbine additional.
Background technology
Along with the cry of energy-saving and emission-reduction grows to even greater heights, Abgasgesetz is stricter, and vehicular engine all starts progressively to have employed PCV system.In PCV system, in engine piston gas blowby air inlet pipeline to be recovered to, this just requires to there is not oil droplet in the gas reclaimed as far as possible, if the machine oil in " can not bypassing gaseous mixture " is removed clean, the burning of engine will be affected and damage air cleaner cartridge, the PM discharge capacity causing engine raises and the adverse consequences such as air filter blocking, and the oil gas scurried out also can reduce the lubricant effect of machine oil in crankcase, increases the consumption of machine oil.This portion of residual waste gas must be made to discharge rapidly crankcase, to ensure the stability of crankcase pressure and temperature, therefore it is required that gs-oil separator meets certain separation requirement.At present, Oil-gas Separation mainly has three kinds: filter net type gs-oil separator, labyrinth type oil-gas separator and cyclone type oil-gas separator.
Summary of the invention
Present invention aim at improving labyrinth type oil-gas separator, it is provided that a kind of simple in construction, easily manufacture, easily assembling and the high oil-gas separator structure of oil-gas separation efficiency.
The present invention solves the technical scheme that technical problem taked:
The present invention includes labyrinth type oil-gas separator, pressure-regulating valve, non-woven fabrics filter core and turbine.
Pressure-regulating valve is arranged on labyrinth type oil-gas separation chamber wall, and the mixing mist of oil from crankcase enters labyrinth type oil-gas separation chamber through pressure-regulating valve and mixing mist of oil air inlet.
Turbine is assemblied on the free end of camshaft, and the import of turbine is provided with the non-woven fabrics filter core that may filter that water oil component in gaseous mixture；The outlet of turbine is connected with labyrinth type oil-gas separator by interface；Described turbine, for improving the flow rate of mixing mist of oil, reduces temperature when miscella spray moves, and improves elaioleucite condensing rate in gs-oil separator and the speed of gas discrepancy gs-oil separator and pressure.
Being provided with the dentation baffle plate being made up of engineering plastics in described labyrinth type oil-gas separator, described dentation baffle plate, for increasing the hit probability of the elaioleucite in mixing mist of oil and wall, makes elaioleucite condensation, adheres to and converge；Elaioleucite passes through oil-recovery tank oil return.
Furtherly, the exit of gs-oil separator connects the outer gas and oil separating plant of machine, improves oil-gas separation efficiency further.
The present invention contrasts prior art and has a following beneficial effect:
1, the labyrinth type oil gas separation structure designed by the present invention, can be effectively reduced in labyrinth the temperature of the mist of oil that flows by being assemblied in the rotation of the turbine on camshaft free end, improves the flow rate of mist of oil, improves the condensing rate of elaioleucite, improves the pressure of gas outlet.
2, the labyrinth type oil gas separation structure designed by the present invention and lobe shape baffle plate, add the impact rate of elaioleucite and wall, machine oil can be made effectively to bond and meet at wall, then by oil return opening oil return, be greatly increased the oil return ratio of machine oil.
3, the non-woven fabrics filter core that the present invention is increased newly can improve the efficiency of Oil-gas Separation.
4, the labyrinth type oil gas separation structure designed by the present invention, can be effectively reduced the exhaust emission of engine, improves the economic benefit of engine, reduces the gas blowby infringement to engine.

Fig. 2 is the design diagram of dentation baffle plate shown in square frame in Fig. 1.
Detailed description of the invention
The present invention relates to the gas oil separation structure design of engine crank case ventilation convexity engineer room, it is desirable to provide a kind of simple and effective Oil-gas Separation cell structure.
As it is shown in figure 1, this structure mainly includes labyrinth type oil-gas separator 1, pressure-regulating valve 6, non-woven fabrics filter core 4 and turbine 3:
Labyrinth type oil-gas separator has the dentation baffle plate being made up of engineering plastics, this baffle plate is assemblied in inside cylinder head with certain structure design form, it is connected with turbine gas outlet, increase the hit probability of the elaioleucite in mixing mist of oil and wall, elaioleucite condensation can be made, adhere to and converge, by oil-recovery tank oil return, and the exit of this gs-oil separator can also connect the outer gas and oil separating plant of other machine, improves oil-gas separation efficiency further.
Pressure-regulating valve makes crankcase pressure keep within the specific limits, prevents the hypertonia in crankcase.
Non-woven fabrics filter core may filter that the water oil component in gaseous mixture.
Turbine is assemblied on the free end of camshaft, the flow rate of mist of oil is mixed in improving cylinder head, reduce temperature when mixing mist of oil flows in cylinder head, improve elaioleucite condensing rate in gs-oil separator, also improve speed and the pressure of gas discrepancy gs-oil separator.
Mixing mist of oil enters Oil-gas Separation room from crankcase by pressure-regulating valve 6 and mixing mist of oil air inlet 5, in flow process, the rotation of turbine 3 will increase the flow rate of mixing mist of oil, mist of oil flows into gs-oil separator by interface 2, increase the impact rate with tooth plate, and reducing the temperature of the high temperature mixing mist of oil flow to from crankcase, make mist of oil faster condense and converge, turbine 3 also can increase the gas after having separated and enter the pressure of air inlet pipe.Labyrinth type oil-gas separator lobe shape baffle arrangement (seeing Fig. 2) will increase mixing mist of oil hit probability of elaioleucite in flow process, improves the condensing rate of elaioleucite.Finally, the gaseous mixture after Oil-gas Separation is complete can connect the outer gs-oil separator of other machine by gas outlet 7 and improve oil-gas separation efficiency further, enters back into engine air inlet tube afterwards, again burns.
