Exhaust structure of compressor, screw compressor and air conditioner unit

Abstract

The invention relates to an exhaust structure of a compressor, the screw compressor and an air conditioner unit. The exhaust structure of the compressor comprises a machine body, an exhaust bearing holder and an oil distribution bucket, wherein the exhaust bearing holder is arranged at the exhaust end of the machine body; the oil distribution bucket covers the exhaust bearing holder; a first exhaust cavity is formed in the exhaust bearing holder; a second exhaust cavity is formed in the machine body; a third exhaust cavity is formed between the exhaust bearing holder and the inner wall of the oil distribution bucket; the first and second exhaust cavities are in fluid communication; the second and third exhaust cavities are in fluid communication; the third exhaust cavity and a discharge opening of the oil distribution bucket are in fluid communication. According to the exhaust structure, air flow first enters the machine body through the exhaust bearing holder and flows out from the machine body, so that the flow path of the air flow is lengthened, the isolation of air flow noise is facilitated and the pulse of the air flow is alleviated.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor exhaust structure, a screw compressor with the compressor exhaust structure, and an air conditioner unit with the screw compressor. Background technique [0002] For semi-hermetic screw compressors, when the compressor does not have a built-in oil separation core, the oil separation barrel is used to surround the exhaust bearing seat, which can reduce noise. At this time, the gas discharged from the compressor enters the inside of the oil separator barrel through the exhaust bearing seat, and then is discharged from the compressor through the outlet of the oil separator barrel. Since the compressor does not have a built-in oil separation core, the outlet of the oil separator barrel must be located at the lower part of the oil separator barrel so that the refrigerated oil carried in the exhaust gas can be discharged from the compressor smoothly. For the screw compressor wi...

Problems solved by technology

In this case, the distance between the discharge port of the exhaust bearing seat and the discharge port of the oil separator barrel is too close, and the noise isolation effect of the oil separator barrel cannot be fully exerted.
