摘要： The present disclosure discloses a connection structure of an exhaust bearing seat for a compressor and a screw compressor, falling within the art of compressors, and designed to solve the problem of large radial vibration of the existing exhaust-end bearing seat. The connection structure of an exhaust bearing seat for a compressor disclosed in the present disclosure comprises an exhaust bearing seat, an oil separation bucket and an oil separation screen assembly all arranged at an exhaust end of a body of the compressor, wherein a tail end of the exhaust bearing seat is connected with the oil separation screen assembly, and an outer periphery of the oil separation screen assembly is provided with a vibration-reducing element, which is connected to an inner wall of the oil separation bucket. The vibration of the exhaust bearing seat is transmitted to the vibration-reducing element through the oil separation screen assembly, and then to the oil separation bucket after being absorbed by the vibration-reducing element, such that the tail portion of the exhaust bearing seat is obviously suppressed from radial vibration. Owing to the adoption of the above-mentioned connection structure of an exhaust bearing seat, the screw compressor provided in the present disclosure has reduced radial vibration at the exhaust-end bearing seat, and is rendered with longer service life and wider application scope.

摘要： Disclosed are an exhaust bearing seat, a screw compressor and an air-conditioning unit. The exhaust bearing seat is provided with a discharge port (1), wherein an opening of the discharge port (1) is orientated in such a way that, if the exhaust bearing seat is sheathed in a housing, gas exhausted from the discharge port (1) has a component which rotates along an inner wall of the housing and around an axial direction of the housing. The discharge port (1) is able to guide the gas flow to rotationally flow along the inner wall of the housing body and around the axial direction of the housing, which extends the flow path of the gas flow inside the housing, and facilitates the reduction of noise of the gas flow pulsation.

摘要： Disclosed is an oil separation barrel, which comprises an oil separation and filtration structure (3) provided in the oil separation barrel, an oil separation cavity and an output port (4). An output gas flow is filtered by the oil separation and filtration structure (3), then enters the oil separation cavity, and finally is output from the output port (4). At least part of the oil separation cavity is provided with two or more layers of circumferential walls. The output gas flow flows in the oil separation cavity in such a manner that it changes the advance direction multiple times, which can make the flow field uniform and reduce noise and vibration; and the output gas flow impacts the circumferential wall surfaces in the oil separation barrel multiple times, which can further improve the efficiency of oil separation. The oil separation barrel is provided in a screw compressor, and the screw compressor is provided in an air conditioning unit.

摘要： Disclosed is a multi-stage compressor, including a gas supplement structure, a low-pressure stage chamber and a high-pressure stage chamber. The gas supplement structure includes a gas supplement inlet (1) and a perforated member (2), wherein the gas supplement inlet (1) is arranged at an upstream location of an exhaust gas flow of the low-pressure stage chamber; the perforated member (2) is arranged at a downstream location of the exhaust gas flow of the low-pressure stage chamber; a liquid refrigerant sprayed from the gas supplement inlet (1) is mixed with exhaust gas of the low-pressure stage chamber to impact on the perforated member (2); the liquid refrigerant is dispersed, the dispersed liquid refrigerants are re-mixed with the exhaust gas of the low-pressure stage chamber and enter the high-pressure stage chamber. The multi-stage compressor achieves the effects that the liquid refrigerant is fully mixed with the exhaust gas of the low-pressure stage chamber and then enters the high-pressure stage chamber to undergo secondary compression, thereby improving the uniformity of a flow field of the supplemented gas and improving secondary energy efficiency.
