A multi-magnet compressor

Abstract

The invention discloses a multi-magnet compressor, which comprises four functional parts: an end cover, a stator assembly, a mover assembly, and a suction and discharge assembly. The end cover includes the left and right end covers; the stator assembly includes the iron casing, the permanent magnet, the insulating plate and the piston casing, etc.; the mover assembly includes the coil frame, the coil group, the movable sleeve, the piston, the piston rod, the piston inner sleeve and the inner stator, etc. , the piston is connected with the piston inner sleeve through the piston rod; the suction and exhaust assembly includes a valve cover, a baffle, an exhaust pipe, a buffer plate, a valve plate and a valve seat, etc.; the coil group is two mutual The coil is wound in the opposite direction and fixed in the annular magnetic field composed of permanent magnet blocks through the coil frame. After the current is passed through, the electromagnetic driving force is generated to drive the moving sub-assembly to move, and then the gas is compressed to do work, compressing the low-pressure gas into a high-pressure gas. Gases have pressure energy. The multi-magnet compressor of the invention has the advantages of compact structure, stable operation, low noise and prolonged service life.

Description

technical field [0001] The invention relates to the technical field of linear compressors, in particular to a multi-magnet linear compressor. Background technique [0002] Compressor equipment is the main energy-consuming part of refrigeration systems such as refrigerators. With the rapid development of industry, traditional reciprocating piston compressors are gradually replaced by linear compressors due to their complex structure and low efficiency. The compressor is a driven fluid machine that lifts low-pressure gas into 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, thereby realizing compression-condensation (heat release) )-expansion-evaporation (endothermic) refrigeration...

AI Technical Summary

Problems solved by technology

At present, the reciprocating compressors on the market usually have the disadvantages of unstable flow rate, larger volume than compressors with the same flow rate, complex mechanism and large amount of capital, many parts, easy to break down, difficult to maintain, etc.
