Reduce use cost.
Fig. 1 and Fig. 2 are refer to, Fig. 1 is the structure chart of the specific embodiment of oil-gas separating device for engine provided by the present invention；
Fig. 2 be oil-gas separating device for engine provided by the present invention specific embodiment in separator body part sectional view.
In a kind of specific embodiment of oil-gas separating device for engine provided by the present invention, including separator body, cylinder body enter
Oil duct 11 and lubricating oil pump.
Separator body includes the case 9 being fixedly connected on cylinder body 10, the rotating shaft 21 being arranged in the case 9, setting
Blade 16 and the driving rotor 15 for being connected to the rotating shaft 21, the vertically-arranged of rotating shaft 21 in the rotating shaft 21.The top of case 9, which is set, to be divided
From device import 8, gas mixture 18 enters inside case 9 from the separator import 8, and the sidepiece of case 9 is provided with separator outlet
Mouth 6, the bottom of case 9 are provided with separator oil-out 20, and the gas isolated is discharged case 9 from separator gas outlet 6, isolated
Oil droplet 17 flow under gravity separator oil-out 20 and from separator oil-out 20 discharge case 9.Wherein, case 9
It can be bolted on cylinder body 10.
Lubricating oil pump is used to convey machine oil.Cylinder body oil input channel 11 is arranged in cylinder body 10, the outlet face of cylinder body oil input channel 11
Driving rotor 15 is set, and lubricating oil pump can convey the machine oil in cylinder body oil input channel 11, so that machine oil sprays to driving rotor 15 and drives
Dynamic driving rotor 15.Driving rotor 15 rotates, while drives rotating shaft 21, blade 16 to rotate, and blade 16 needs to design according to operating mode
Into proper angle, the oil droplet 17 in high speed rotation state makes gas mixture 18 separates from gas and is thrown to case 9
On inwall, then the separator oil-out 20 of case 9 is downwardly towards under gravity.
In oil-gas separating device for engine in the present embodiment, driving rotor 15 is driven to rotate by machine oil, so as to pass through rotating shaft
21 band movable vane pieces 16 rotate, and are separated using the principle of the centrifugation oil droplet 17 different to density and gas, meanwhile, machine oil
Pump can be according to different Operating condition adjustment engine oil pressures, and then change the rotating speed of driving rotor 15, without setting filter core, are not present
Dirt blocks the situation of filter core, and service life is longer, can ensure separative efficiency, reduce the O＆M cost of user,
Dirt of the engine crankshaft ventilation system to environment can be effectively improved on the basis of the requirement such as balance crankshaft case pressure is met
Dye, avoid the seal leakage situation caused by crankcase pressure is excessive and occur.
On the basis of above-described embodiment, separator gas outlet 6 can set pressure-regulating valve 7, the gas warp isolated
Pressure-regulating valve 7 enters in engine charge pipeline from separator gas outlet 6, and pressure-regulating valve 7 can be according to gas handling system
Air-flow in pressure regulation separator body, realizes and the pressure inside crankcase is adjusted.
On the basis of any of the above-described embodiment, the oil-gas separating device for engine can also include in cylinder cover enclosure 1
Oil gas pre-separating cavity 3, the pre-separating cavity import 2 of oil gas pre-separating cavity 3 located at the top of cylinder cover enclosure 1, oil gas pre-separating cavity 3
Pre-separating cavity outlet 4 connects separator import 8 by connecting tube 5.Oil gas pre-separating cavity 3 is specifically as follows annular seal space.Oil gas mixes
When by pre-separating cavity import 2, sectional area reduces compound 18, and flow velocity is increased, and gs-oil separator can be carried out by Action of Gravity Field
Pre-separation, the gas isolated can be expelled directly out from pre-separating cavity import 2, and the gas mixture 18 after pre-separation is through pre-
Disengagement chamber outlet 4, connecting tube 5 drain into separator import 8.
In the present embodiment, oil gas pre-separating cavity 3 is arranged on cylinder cover enclosure 1, can be avoided because being splashed inside crankcase
The more and inconvenient exhaust of machine oil, gas mixture 18 need to enter back into separator sheet after the initial gross separation of oil gas pre-separating cavity 3
In body, separated again by separator body using centrifugal force after a pre-separation, separative efficiency can be improved.
On the basis of any of the above-described embodiment, cylinder body oil input channel 11 can include the oil-feed for being connected to the vertically-arranged of lubricating oil pump
Section and horizontal fuel-displaced section for being connected to oil-feed section, to better adapt to the structure of cylinder body 10, and can ensure the smooth of machine oil
Flowing.
On the basis of above-described embodiment, the fuel-displaced section of fuel feed pump 13 that can specifically include being connected to oil-feed section and detachable
It is connected to the spray bar 14 of fuel feed pump 13.Spray bar 14 is arranged to replaceable, starts motivation often with operating mode by matching
Air leakage, suitable spray bar 14 may be selected and installed, flow direction driving rotor 15 is adjusted by this diameter of spray bar 14
Oil flow rate, realize to drive rotor 15 rotating speed regulation, gs-oil separator can be met to engine crankcase pressure
Control, make this section separative efficiency highest.
On the basis of any of the above-described embodiment, the outlet of separator oil-out 20, cylinder body oil input channel 11 passes through oil return
Passage is communicated in cylinder body oil return opening 12, and the oil baffle 19 for the oil droplet 17 for being used to block bent axle splashing can be provided with drainback passage.
Because the splashing oil droplet 17 of crankshaft high-speed rotation can get rid of many machine oil into cylinder body oil return opening 12, cause to return at cylinder body oil return opening 12
Oil is not smooth, by the setting of oil baffle 19, can avoid bent axle because the oil droplet 17 of high speed rotation splashing is through separator oil-out 20
It is back in case 9.
On the basis of above-described embodiment, reinforcement can be connected between oil baffle 19 and drainback passage, to ensure to keep off
The intensity of oiled-plate method 19.
On the basis of above-described embodiment, the top of oil baffle 19 can be fixedly connected on drainback passage, and oil baffle 19
Bottom interval can be provided between drainback passage, the oil droplet 17 for making to isolate flows to cylinder body oil return from the lower section of oil baffle 19
Mouth 12, oil baffle 19 is avoided to interfere the flowing of oil droplet 17.
Except above-mentioned oil-gas separating device for engine, present invention also offers one kind to include engine disclosed in above-described embodiment
The engine of gs-oil separator, the engine can improve separative efficiency, drop as a result of above-mentioned oil-gas separating device for engine
Low use cost.The structure of other each several parts of the engine refer to prior art, repeat no more herein.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.
Engine provided by the present invention and its oil-gas separating device for engine are described in detail above.Herein should
The principle and embodiment of the present invention are set forth with specific case, the explanation of above example is only intended to help and managed
Solve the method and its core concept of the present invention.It should be pointed out that for those skilled in the art, do not departing from
