Upper flange component and compressor

Abstract

The invention provides an upper flange component. The upper flange component comprises a bearing and an exhausting partition plate; the exhausting partition plate is fixed to the lower end of the bearing and is provided with an air flow passage; the lower end of the air flow passage is provided with an exhaust vent which communicates with the air flow passage; an exhaust valve component used for controlling the opening and closing of the exhaust vent is fixedly arranged inside the air flow passage; the bearing is provided with a bearing exhaust passage which communicates with the air flow passage; and the end, far away from the exhaust vent, of the exhausting partition plate is further provided with a partition plate exhaust passage which communicates with the air flow passage. The upper flange component can reduce the oil output of the compressor in order to prevent the problem about compressor faults caused by reduction of oil amount inside the compressor and deficiency of oil supplypumpage, can also prevent refrigerant oil from entering a system so that oil films are not formed on the surface of a heat exchanger and reduces adverse effects generated on the heat exchanger of anair conditioner so that the performances of an air conditioning system are not affected.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an upper flange assembly and a compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle; thus realizing compression → condensation (heat release )→expansion→evaporation (endothermic) refrigeration cycle. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. The entry introduces the working principle, classification, accessories, specifications, operation requirements, production of compressors, common faults and ...

AI Technical Summary

Problems solved by technology

[0003] However, during the operation of the rotary compressor in the prior art, a large amount of lubricating oil is carried into the upper space of the compression mechanism by the refrigerant airflow, and is discharged from the compressor with the refrigerant, forming an oil discharge volume (during the operation of the hermetic rotary compressor, A large amount of refrigeration oil is carried by the refrigerant airflow into the upper space of the motor, where separation occurs, and the separated lubricating oil flows back down along the gap between the housing and the motor, and the unseparated tiny oil droplets are discharged with the refrigerant airflow Compressor, forming oil discharge), forming an oil film on the surface of the heat exchanger, which will have a negative impact on the heat exchanger of the air conditioner and affect the performance of the air conditioning system
