COMPRESSOR EXHAUST STRUCTURE, SCREW COMPRESSOR AND AIR-CONDITIONING UNIT HAVING SAME

摘要

Disclosed are a compressor exhaust structure, a screw compressor and an air-conditioning unit, wherein the compressor exhaust structure comprises a machine body (2), an exhaust bearing seat (1) provided on an exhaust end of the machine body (2), and an oil separating barrel (5) covering the exhaust bearing seat (1). The exhaust bearing seat (1) is provided with a first exhaust chamber, the machine body (2) is provided with a second exhaust chamber (21), and a third exhaust chamber is formed between the exhaust bearing seat (1) and an inner wall of the oil separating barrel (5); the first exhaust chamber is in fluid communication with the second exhaust chamber (21), the second exhaust chamber (21) is in fluid communication with the third exhaust chamber, and the third exhaust chamber is in fluid communication with a discharge port of the oil separating barrel (5). The above-mentioned compressor exhaust structure enables gas flow to firstly enter the machine body (2) via the exhaust bearing seat (1) and then to flow out of the machine body (2), which extends the flow path of the gas flow, facilitates the isolation of gas flow noise, and reduces gas flow pulsation.
