The present disclosure is related to a slide valve, a slide valve adjustment mechanism and a screw compressor. The slide valve includes a static slide valve and a moving slide valve, wherein the static slide valve is fixedly installed in a slide valve cavity and provided with an axially-penetrating valve hole; a plurality of bypass holes communicating with the valve hole () are formed in the sidewall of the static slide valve, and an exhaust port is formed in the sidewall of one end of the static slide valve. The slide valve may avoid scraping between the slide valve and a screw rotor and the slide valve cavity. Gaps between the slide valve and parts which cooperate with same are reduced, so that the leakage is reduced while the energy efficiency of the compressor is increased.

Slide valve, slide valve adjustment mechanism and screw compressor

Some embodiments of the present disclosure provide a slide valve for a compressor and a screw compressor with the slide valve. The slide valve for the compressor includes a slide valve main body (), the slide valve main body () is provided with a gas replenishing chamber () therein, a surface, facing to a compression chamber of the compressor, of the slide valve main body () is provided with a gas replenishing outlet hole (), and the gas replenishing outlet hole () is in communication with the gas replenishing chamber ().

Slide valve for compressor and screw compressor with slide valve

Disclosed is an oil separation barrel, which includes a barrel body and an oil separation and filtration structure provided in the barrel body, the barrel body provided with an oil separation cavity and an output port. An output gas flow is filtered by the oil separation and filtration structure, then enters the oil separation cavity, and finally is output from the output port. At least part of a barrel wall of the barrel body forming the oil separation cavity includes 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.

Oil separation barrel, screw compressor and air conditioning unit

Disclosed is a connection structure of an exhaust bearing seat for compressors and screw compressors, designed to solve the problem of large radial vibration of the existing exhaust-end bearing seat. The connection structure includes 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 and suppressed by the vibration-reducing element.

Connection structure of exhaust bearing seat for compressor and screw compressor

A screw compressor and a compressor body thereof, in which the compressor body includes 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.

Screw compressor and a compressor body thereof

A compressor exhaust structure includes a machine body, an exhaust bearing seat provided at an exhaust end of the machine body and an oil separating barrel covering the exhaust bearing seat, the exhaust bearing seat is provided with a first exhaust chamber, the machine body is provided with a second exhaust chamber, a third exhaust chamber is formed between the exhaust bearing seat and an inner wall of the oil separating barrel, the first exhaust chamber is in fluid communication with the second exhaust chamber, the second exhaust chamber 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. The compressor exhaust structure increases the flow path of the gas flow, facilitates the insulation of gas flow noise and reduces gas flow pulsation.

Compressor exhaust structure, screw compressor and air-conditioning unit having same

An exhaust bearing seat, a screw compressor and an air-conditioning unit are provided. The exhaust bearing seat is provided with a discharge port, wherein an opening of the discharge port is orientated in such a way that, if the exhaust bearing seat is sheathed in a housing, gas exhausted from the discharge port has a component which rotates along an inner wall of the housing and around an axial direction of the housing. The discharge port 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.
