Compressor and refrigeration system provided with same

Abstract

The invention discloses a compressor and a refrigeration system provided with the compressor. The compressor comprises a shell, a crankshaft, a first air cylinder, a second air cylinder, a central partition plate, a first flange, a second flange, a first cover plate and a second cover plate, wherein the crankshaft, the first air cylinder and the second air cylinder are arranged inside the shell, the central partition plate is arranged between the first air cylinder and the second air cylinder; partition plate air inlet grooves which are respectively communicated with the first air cylinder and the second air cylinder are formed in the two lateral sides of the central partition plate and communicated with each other through a through hole which penetrates through the central partition plate; the first flange is connected with the first air cylinder; the second flange is connected with the second air cylinder; the first cover plate is arranged on the first flange; the second cover plate is arranged on the second plate; a first sliding sheet groove is formed in the first air cylinder to contain a first sliding sheet; a second sliding sheet groove is formed in the second air cylinder to contain a second sliding sheet; a spring is arranged at the tail part of the first sliding sheet and a pin nail used for locking the second sliding sheet is arranged at one side of the second sliding sheet. According to the compressor, the shift of air suction is avoided and the stability of air suction of the compressor is guaranteed.

Description

technical field [0001] The invention relates to the field of compressors, in particular, to a compressor and a refrigeration system having the same. Background technique [0002] In the prior art, there is a technology of applying a single-pipe liquid distributor to a double-cylinder compressor. The main reason is that a suction hole is arranged on the middle partition of the compressor, and the suction hole is connected with the inlet of the first cylinder and the second cylinder. The inlets communicate with each other, and one end of the external suction pipe communicates with the suction hole, and a distance increasing device is arranged in the suction hole to lengthen the distance between the entrance of the first cylinder chamber and the entrance of the second cylinder chamber. The distance extender includes a dividing plate inserted into the suction hole, and the dividing plate separates the inlet of the first cylinder chamber and the inlet of the second cylinder chamb...

AI Technical Summary

Problems solved by technology

This will reduce the suction efficiency of the compressor and affect the performance of the compressor

[0003] In this scheme, permanent magnets, electromagnets, tension springs and other holding mechanisms are used to provide a pulling force to the outside of the cylinder to realize the separation of the sliding plate and the roller during single-cylinder operation. The lower slide presses the rollers, and the tension still exists, which will increase the leakage of the second cylinder and affect the performance and stability of the compressor
