Balance block, rotor component and compressor

Abstract

The invention discloses a balance block, a rotor component and a compressor. The balance block is suitable for rotating around a rotating center line, and comprises a body and a fixing part; the bodyis provided with a first side face and a second side face arranged opposite to each other in the width direction of the body; the first side face is closer to the rotating center line than the secondside face; the second side face is an arc-shaped face protruding in the direction away from the rotating center line; the fixing part is arranged at the end in the length direction of the body and provided with a third side face and a fourth side face in the width direction of the fixing part; the third side face is closer to the rotating center line than the fourth side face; the fourth side faceis an arc-shaped face protruding in the direction away from the rotating center line; and on the projection plane orthogonal to the rotating center line, the distance between the projection of the rotating center line and the projection of the second side face is L1, the distance between the projection of the rotating center line and the projection of the fourth side face is L2, and L2 is largerthan L1. The wind resistance borne by the balance block in the working process is small, and the reliability of the compressor in the running process can be improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a balance weight, a rotor part with the balance weight and a compressor with the rotor part. Background technique [0002] In the related art, the upper end or the lower end of the rotor of the rotary compressor is generally provided with a balance weight. When the compressor is working, the balance weight will also rotate accordingly. Because the rotation of the balance weight has a certain wind resistance, it will cause a strong cyclone in the upper or lower space of the motor, which will cause the instability of the oil pool of the compressor and lead to the oil loss of the compressor. The surface is difficult to guarantee, which reduces the reliability of the compressor operation. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, an embodiment ...

AI Technical Summary

Problems solved by technology

When the compressor is working, the balance weight will also rotate accordingly. Due to the certain wind resistance caused by the rotation of the balance weight, a strong cyclone will be formed in the upper or lower space of the motor, which will cause the instability of the oil pool of the compressor and lead to the oil loss of the compressor. It is difficult to guarantee the surface, which reduces the reliability of compressor operation
