Magnetic drive reciprocation refrigeration compressor

Abstract

The invention relates to the technical field of compressors, in particular to a magnetic drive reciprocation refrigeration compressor. The magnetic drive reciprocation refrigeration compressor comprises a machine case and an air cylinder fixedly connected with the machine case, one end of the machine case is provided with a first passage, the other end of the machine case is provided with a secondpassage, one end of the air cylinder is provided with a first valve for controlling the first passage to be opened and closed, and the other end of the air cylinder is provided with a second valve for controlling the second passage to be opened and closed; and the air cylinder is internally provided with a permanent magnet mover, and the two ends of the machine case are provided with magnetic drive mechanisms for driving the permanent magnet mover to reciprocate in the air cylinder. Alternating current which is equal in intensity and opposite in phase position is led into the magnetic drive mechanism, and reciprocating motion of the permanent magnet mover in the air cylinder can be achieved; magnetic drive can replace motor drive inside a conventional refrigeration compressor, a movementmechanism of the compressor can be simplified, the volume and quality of the compressor are reduced, the possibility of failures is reduced, the noise is effectively controlled, and the stability andefficiency of the compressor are improved.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a magnetically driven reciprocating refrigeration compressor. Background technique [0002] Due to the reciprocating motion of the traditional piston refrigeration compressor using the crank connecting rod mechanism, under the influence of the reciprocating inertial force, the speed of the motor cannot be too fast. In order to meet the requirements of cooling capacity, the volume of the cylinder can only be increased to improve each suction capacity. The volume of the gas; the cost of making this change is that the volume and mass of the entire compressor will increase. The volume and mass of the traditional piston refrigeration compressor are often 160% to 200% of the volume of the rolling rotor compressor. In addition, during the operation of the piston refrigeration compressor, the crank linkage mechanism will convert the rotational motion of the motor into the rec...

Problems solved by technology

Furthermore, the piston refrigeration compressor has a complex structure, the overall structure is not symmetrical, and there are many moving parts. It is constantly subjected to alternating loads during operation, and is prone to vibration, which has a serious impact on the stability of the compressor. Faults, resulting in discontinuous gas transmission and fluctuations in gas pressure during the working process, which will affect the cooling effect of the refrigerator
