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： 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： The embodiments of the present application disclose a screw compressor and a compressor body thereof, in which the compressor body comprises a housing provided with a suction inlet and a discharge end face, the housing is internally provided with a rotor chamber and a spool chamber, the housing is provided with a cooling chamber around the rotor chamber, the cooling chamber communicates with the suction inlet, and the cooling chamber is provided with an air inlet communicating with the rotor chamber. A coolant after entering the suction inlet, first enters the cooling chamber, and then enters the rotor chamber via the air inlet. By means of such structural design, the coolant subject to air suction forms a flow in the cooling chamber. As the coolant subject to air suction has a lower temperature, and the outer wall of the rotor chamber has a higher temperature, by means of a coolant flow, the rotor chamber can be sufficiently cooled, such as to avoid an excessively high discharge temperatures. Moreover, the coolant flow can also sufficiently absorb noise and vibration radiated from the rotor chamber, so as to further reduce overall machine noise of the compressor.
