Exhaust components and compressors

Abstract

The invention relates to an exhaust assembly and a compressor, wherein the exhaust assembly includes an exhaust bearing seat, the air intake end of the exhaust bearing seat is provided with an air intake cavity, and the exhaust end of the exhaust bearing seat is provided with There is an exhaust cavity, the air intake cavity and the exhaust cavity are staggered along the axial direction of the exhaust bearing seat, and the exhaust bearing seat is provided with a connection between the air intake cavity and the exhaust cavity The flow channel, the oil separation structure is arranged in the exhaust cavity. In the embodiment of the present invention, the intake cavity and the exhaust cavity are staggered along the axial direction of the exhaust bearing seat, and the exhaust of the intake cavity is led to the exhaust cavity by setting a flow channel, and an oil separation structure is arranged in the exhaust cavity. It can make full use of the space at the exhaust end of the exhaust bearing seat and install the oil separation structure, which solves the problem that the oil separation structure occupies a large space in the prior art and cannot be installed due to space constraints; moreover, by setting the oil separation structure, the oil content of the exhaust gas can be significantly increased The amount of effective compressed refrigerant increases, and the energy efficiency is significantly improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an exhaust assembly and a compressor. Background technique [0002] In a single-unit two-stage screw compressor, the first-stage exhaust gas cools the motor and then enters the second-stage compression chamber. In order to reduce the temperature and lubricate the bearing, it is necessary to inject refrigerated oil into the bearing chamber, and the refrigerated oil in the bearing chamber will eventually return to the second stage. In the rotor cavity of the stage, it flows out with the exhaust gas. For conventional single-stage screw compressors, there is only one stage of rotor, and the amount of refrigerated oil returned to the rotor cavity is not large. Most of the refrigerated oil can be filtered out through the built-in oil separation structure, which has little impact on energy efficiency. [0003] For a single-unit two-stage screw compressor, there is not only the retu...
