Compressor rotor sealing structure and rotor assembly thereof

Abstract

The invention discloses a compressor rotor sealing structure and a rotor assembly therefore. The compressor rotor sealing structure comprises a machine body, an assembling base is connected and positioned at a mounting opening of the machine body in a clamped manner, a sealing end cover is connected and positioned at the upper end of the assembling base in a clamped manner, a shaft sleeve is tightly connected with a rubber sealing sleeve plate in a sleeved manner, and the rubber sealing sleeve plate is fixedly connected with a sealing clamping base. Through the shaft sleeve, the rubber sealingsleeve plate and graphene wear-resistant gear rings, wear to a rotor shaft part is greatly avoided, and therefore the sealing performance of the structure is effectively enhanced; through a bearing seat, a sealing top cover, an inner sealing washer and a resin filling block, the sealing performance of a bearing body is effectively enhanced, the vibration wear phenomenon can be reduced easily, andtherefore the sealing performance of the structure is further enhanced; and through a polyester supporting plate, a silicon rubber plate, separation cavities and springs, the anti-vibration protection effect of the sealing clamping base is enhanced, and therefore operation stability and sealing performance of a rotor are enhanced again, the use efficiency of the rotor is improved, and then the working efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of compressor equipment, and in particular relates to a compressor rotor sealing structure and a rotor assembly thereof. Background technique [0002] The compressor is a driven fluid machine that upgrades low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston through the motor to compress it, and sends it to the compressor. The exhaust pipe discharges high-temperature and high-pressure refrigerant gas to provide power for the refrigeration cycle. The compressor is generally composed of an upper cover, a lower cover, a shell, a motor fixed inside the shell to provide rotational power, and a pump body that realizes refrigerant compression. The main components are cylinder block, piston, valve plate, connecting rod, crankshaft, end cover, rotor, stator, etc. Among them, the rotor is ...

AI Technical Summary

Problems solved by technology

Among them, the rotor is an important part of the compressor. The high-speed operation of the rotor and the vibration and wear of the bearing and assembly seat after long-term use make the rotor connection very prone to poor sealing, which in turn easily leads to hidden dangers of leakage loss inside the body.
