Motor for compressor and compressor

Abstract

The invention discloses a motor for a compressor and the compressor. The motor includes a rotor and a balancing block, the balancing block is arranged at least one end of the axial two ends of the rotor, the balancing block includes a balancing seat and a balancing base body arranged at one side, far away from the rotor, of the balancing seat, the outer surface of the balancing base body is a smooth curved surface, or the outer surface of the balancing base body is formed by a plurality of planes similar to the smooth curved surface, or the outer surface of the balancing base body is the combination of the curved surface and the planes. According to the invention, the outer surface of the balancing base body is the smooth curved surface, or is formed by a plurality of planes similar to the smooth curved surface, or is the combination of the curved surface and the planes, so that the wind resistance is reduced, the air-flow disturbance is improved, the energy efficiency of the compressor is improved to some extent, and air-flow noises can be reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a motor and compressor used for compressors. Background technique [0002] In the related art, balance weights are usually arranged on the upper and lower end surfaces of the rotor of the motor of the compressor to prevent the rotor from being unbalanced due to the misalignment of the center of gravity of the piston and the rotation center of the eccentric crankshaft when the rotor rotates at high speed. However, during the high-speed operation of the rotor, on the one hand, the windward side of the balance block will rub against the refrigerant discharged from the compression chamber, resulting in wind resistance and affecting the energy efficiency of the compressor; on the other hand, the leeward side of the balance block will generate eddy currents when the refrigerant flows through Increase the airflow disturbance, affect the refrigerant flow field, and reduce the energy ...

AI Technical Summary

Problems solved by technology

However, during the high-speed operation of the rotor, on the one hand, the windward side of the balance block will rub against the refrigerant discharged from the compression chamber, resulting in wind resistance and affecting the energy efficiency of the compressor; on the other hand, the leeward side of the balance block will generate eddy currents when the refrigerant flows through Increase the air flow disturbance, affect the refrigerant flow field, and reduce the energy efficiency of the compressor

At the same time, the gas coming out of the muffler of the compressor will generate fluid turbulence near the inner diameter side of the balance weight, causing air flow disturbance and air flow noise
