It is thrown out of in sliding slot under the action of centrifugal force and is in close contact with stator by oil film, between two neighboring slide plate and stator inner wall
A closed air chamber, as air compression chamber are formed, when rotor rotates, the volume of air compression chamber is with the slide plate amount of skidding off
Size and change, in breathing process, air is inhaled into compression chamber via filter, and mixed with the lubricating oil that sprays into host
It closes, in compression process, the volume of compression chamber is gradually reduced, and pressure gradually rises, and gas mixture is arranged by exhaust outlet later
Out, into Oil-gas Separation is carried out in oil tank, the pressure in general oil tank is exactly defined rated operating pressure, even if not
In the case where load, the pressure in oil tank also has 0.3-0.4MPa, and the small molecule oil filtered through oil core can be hoarded in oil
The bottom of core is discharged into the inlet chamber of sliding-vane air compressor host by oil oil return pipe, is arranged in oil oil return pipe
While oil enters the inlet chamber of sliding-vane air compressor host, the high pressure gas in oil tank can also enter air pressure together
In the inlet chamber of contracting machine host, as without pressure air, is compressed by air compressor main machine and produce gas, it is unrestrained in vain to cause stress air
Take, influences the power consumption and energy consumption of chip air compressor.Simultaneously in order to reduce oil gas leakage, can be provided on oil oil return pipe
Unidirectional return valve and throttling pore, in long-time use process, throttling pore is easy blocking, influences the exhaust of oil oil return pipe
And oil return, it uses very unstable, it has not been convenient to repair.
Utility model content

The oil return hole is provided on the compression chamber between the inlet chamber and discharge chamber of sliding-vane air compressor host.
In order to better solve above-mentioned technical problem, the further technical solution that the utility model uses is: in the oil
The oil oil return pipe lower end of point in-core is provided with oil return opening, the upper end of the oil return opening is pyramidal structure, the pyramidal structure
Bottom is provided with opening, upper tongue and lower tongue is connected in the lower end of the pyramidal structure, between the upper tongue and lower tongue
It is provided with the oil return flat passage with opening in communication, the lower end and two sides of the oil return flat passage are connected with the external world.
The utility model has the advantages that: above-mentioned sliding-vane air compressor oil tank oil oil return system can make oil
Pressure-air in tank is passed straight back in the compression chamber of sliding-vane air compressor host, reduces host secondary compressed air
Power consumption and energy consumption reduce cost squeeze.The structure for changing simultaneously oil oil return pipe lower end oil return opening is not influencing oil gas flux
In the case of, it effectively prevent oil oil return pipe and return check valve to block, structure is simple, easy to process.
