Problems solved by technology

This invention uses a moving magnet linear motor to drive the compressor, but since the radial stiffness of the coil spring is almost zero, the lateral force will inevitably cause the lateral wear of the cylinder and the piston, thereby shortening the service life of the compressor; using the coil spring The position of the maximum compression to prevent the collision between the piston and the cylinder has problems in actual

Abstract

The present invention relates to a moving-magnet straight-line compressor. It includes a linear motor component, it mainly has inner and outer magnetic yokes with concentric combined structure, moving-magnet coil, permanent magnet and motor runner bracket, the permanent magnet is positioned on the motor rotor bracket and placed in the magnetic field formed from inner and outer magnetic yokes; a compressor component, it mainly has machine seat, cylinder, exhaust valve and suction valve which are positioned on the machine seat and piston connected with motor runner; and a machine shell which is seal-connected with machine seat. It is characterized by that it also includes a suspension component, it mainly has a spring support frame, flexible springs, inner and outer washers and collision-prevention mechanism, etc.

Description

Technical field: [0001] The invention relates to a linear compressor, which belongs to the field of compressors in mechanical engineering. Background technique: [0002] The compression refrigeration cycle is one of the main methods of refrigeration, and it is widely used in the fields of refrigerators, refrigeration, air conditioning and low temperature engineering, so the compressor is compared to the heart of the refrigeration and air conditioning system. Refrigeration and air-conditioning compressors consume a lot of electricity when they work, and their electricity consumption accounts for more than half of the total electricity consumption of residents. Therefore, energy saving is always an eternal topic in the refrigeration and air-conditioning industry. In 2003, China's refrigerator market fully implemented the new energy efficiency standards, further illustrating the urgency of energy conservation research. Most of the traditional refrigerator compressors are reci...
