Description
Technical field
The present invention relates to Compressor Technology field, more particularly, it relates to a kind of compressor and oil guard thereof.
Background technology
Compressor includes electric motors function part and compression function part, and wherein, electric motors function part includes stator and rotor,
Compression function part includes bent axle and cylinder.During compressor operating, rotor banding dynamic crankshaft rotate, so realize in cylinder cold
Matchmaker compresses.
But, compressor in the course of the work, discharge at crankshaft center, stator and rotor airgap by oil, and oil mass is very big, oil
Gas-liquid mixture can be formed with the high-pressure gaseous coolant in compressor and be expelled to compressor, and enter in heat exchanger components, as
This, on the one hand can cause the oil mass in compressor to gradually decrease, and affects the lubricant effect of compressor part, reduces making of compressor
Use the life-span；On the other hand, during oil enters heat exchanger components, heat exchange efficiency is affected.
In consideration of it, some compressors on market, rotor is provided with leakproof oil cap, drives leakproof oil cap quick by rotor
Rotating, leakproof oil cap separates oil and gas by the effect of centrifugal force, it is to avoid oil is discharged along with gas.
But, in prior art, compressor oil drain quantity in the course of the work is very big, relies on leakproof oil cap to be difficult to block in a large number
Oil, effect is poor.
Therefore, how to solve the oil guard of compressor in prior art, the problem that gear oil effect is poor, become this area
Technical staff's important technological problems to be solved.
Summary of the invention
