Rotary compressor

Abstract

This invention relates to a rotational compressor including a closed container, an electro-mechanical part and a compression mechanical part, in which, the closed container is composed of a cylindrical shell, a top cover and a bottom cover and one side of the top cover is mounted with a supply connecting device, the electro-mechanical part is composed of a stator and a rotor, the compression part is composed of a piston, an upper bearing, a lower bearing, a crank and a rolling loop, said supply connecting device includes a location post mounted on one side of the top cover vertically, three connection posts set in distance with the location post and 120deg. to each other and set with connection sockets on the top and one plug component connected with the three supply lines and capable of plugging on the sockets on the top of the three connection posts simultaneously.

Description

technical field [0001] The present invention relates to a rotary compressor. Background technique [0002] In general, a compressor is a machine that compresses a fluid. This compressor is composed of a closed container with a certain internal space, an electromechanical part installed in the closed container to generate a driving force, and a compression mechanical part that can compress fluid by using the driving force of the electromechanical part. Fig. 1 is a sectional view of the longitudinal structure of a prior art rotary compressor. As shown in FIG. 1, the airtight container of this prior art rotary compressor consists of a cylindrical casing 3, an upper cover 4 and a lower cover 5. As shown in FIG. A refrigerant inlet 1 is provided on one side of the casing 3 , a refrigerant outlet 2 is provided at the center of the upper cover 4 , and a power wiring device 7 is installed on one side of the upper cover 4 . The electromechanical part located on the upper part of t...

AI Technical Summary

Problems solved by technology

But, there is following problem in this rotary compressor of prior art: when assembling power wiring device 7, operator needs to insert three wiring plugs 10 on the wiring socket of each binding column 9 upper ends one by one, and then use A protective cover is buckled on the outside of the power wiring device 7, and another fixing device is used to fix it on the fixing column 9 from the center of the top surface of the protective cover to complete the assembly process. This wiring method requires the operator to carefully distinguish and confirm the corresponding Wiring sockets and wiring plugs, so the production efficiency is low, and once the wiring is wrong, it will cause the compressor to malfunction
