Closing form can be used in the top in road, and opens up side oil outlet 7 ' between the upper flange 3 ' and motor 4 ' of the pump housing, is set due to this
The flow of lubrication of each motive position of pump body can be improved in meter, is widely used.
With the application of frequency-changeable compressor, when the high revolving speed of compressor is run, above-mentioned side oil outlet 7 ' can spray lubricating oil,
The pump housing is discharged under the action of air-flow and motor upper and lower cavity pressure difference, and a large amount of lubricating oil is taken to motor epicoele, and with compressor
Exhaust enters air-conditioning system.
Using the compressor of this structure, under the influence of centrifugal force, lubricating oil a is flowed out from 7 ' high speed of side oil outlet,
Under the action of the air-flow b that pump housing exhaust outlet 9 ' is discharged, air-fuel mixture stream c is formed, it is logical by rotor recirculation hole, rotor gap etc.
Road enters motor epicoele, eventually leads to a large amount of lubricating oil discharge compressors.
Defect existing for this structure bring harm: first is that cause lubricating oil circulation rate higher, more lubricating oil into
After entering air-conditioning system, air-conditioning heat transfer effect is affected, reduces the performance of air-conditioning；Second is that compressor memory oil mass is easy to cause to subtract
Few, oil level decline causes oil starvation inside compressor, leads to compressor inordinate wear, reliability sharply declines.
Summary of the invention
The present invention is intended to provide a kind of compressor for reducing lubricating oil and entering air-conditioning system.
To achieve the goals above, the present invention provides a kind of compressors, including motor, the crankshaft connecting with motor driven
With the upper flange and lower flange being coaxially disposed with crankshaft, compressor further include: central oil passage, central oil passage are arranged in crankshaft
And it is consistent with the extending direction of crankshaft, the entrance of central oil passage is arranged on the end face of one end of the separate motor of crankshaft；Side goes out
The import of oilhole, side oil outlet is connected with central oil passage, and the outlet of side oil outlet is arranged on the outer peripheral surface of crankshaft and is located at
Between motor and upper flange；Oil guard, be located in the outlet of side oil outlet and between the outer peripheral surface of crankshaft formed and side
The fuel-displaced interval that the outlet of oil outlet communicates.
Further, oil guard is the oil scraper ring being set on crankshaft.
Further, oil scraper ring is coaxially disposed with crankshaft, and oil scraper ring is arranged on the upper surface of upper flange.
Further, oil scraper ring and upper flange are integrally formed.
Further, oil scraper ring is set on upper flange.
Further, the opening for removal of lubricant is offered on oil scraper ring.
Further, compressor further includes the pump housing exhaust outlet that the side of crankshaft is arranged in, and opening exists with pump housing exhaust outlet
The circumferentially-spaced setting of upper flange.
Further, the internal diameter of oil scraper ring gradually contracts by the upper surface of upper flange along the direction of upper flange to motor
It is small.
It applies the technical scheme of the present invention, compressor includes central oil passage, side oil outlet and oil scraper ring, central oil passage setting
Extending direction in crankshaft and with crankshaft is consistent, and oil scraper ring is set on crankshaft and relatively sets with the outlet of side oil outlet
It sets.It applies the technical scheme of the present invention, efficiently reduces lubricating oil and enter air-conditioning system, improve the heat transfer effect of air-conditioning.Into
One step, it alleviates compressor memory oil mass and reduces and lead to the problem of causing oil starvation inside compressor.
