The utility model has the beneficial effects that：
1, gs-oil separator combines the mode of centrifugation and multi-stage separation, and gas mixture is made tangentially to be revolved by air inlet pipe
Turn collision to enter in lower housing, the multiple conical baffles then passed through in lower housing are detached step by step, finally will be after separation
Gas from lower housing bottom to upper shell be discharged, increase the area and time that gas mixture is contacted with conical baffle,
Improve the effect of Oil-gas Separation；
2, the demarcation strip between upper shell and lower housing is set as cone, increases and is tangentially rotated into down by air inlet pipe
The gas mixture of shell and the contact-impact of demarcation strip, further improve oil gas separation；
3, the notch of conical baffle outer rim setting and the through-hole of surface setting play the role of classified filtering, make heavier
Air-fuel mixture composition granule mainly filtered by notch, lighter air-fuel mixture composition granule is mainly filtered by through-hole, is improved point
From efficiency；
4, in gs-oil separator, what is be detachably connected has a demarcation strip and lower housing, conical baffle and lower housing, this
Structure makes Quick-detachable cleaning inside gs-oil separator.
To sum up, the oil-gas separator structure is simple, is readily disassembled cleaning, and combines centrifugation and multi-stage separation
Mode, makes the tangential rotary collision of gas mixture enter separation chamber, then detaches step by step, and gas is from bottom to top discharged, and improves
Separative efficiency and separating effect.
