Scroll compressor with axial magnetic suspension structure

Abstract

The invention discloses a scroll compressor with an axial magnetic suspension structure. A first magnetic component is embedded in a movable scroll plate; a second magnetic component is embedded in anupper support piece; the movable scroll plate and the upper support piece are separated from each other by repulsive force generated by the first magnetic component and the second magnetic component;the first magnetic component is arranged along the circumferential direction of the movable scroll plate, and the first magnetic component has a first magnetic surface facing downwards; the second magnetic component is arranged along the circumferential direction of the upper support piece, and the second magnetic component has a second magnetic surface facing upwards; and the first magnetic surface and the second magnetic surface repel each other. According to the scroll compressor, the pressure between the movable scroll plate and the upper support piece is reduced by the magnetic componentwith the repulsion action surface, the power consumption is greatly reduced, the friction heat is reduced, the reliability is enhanced, and the structure is more compact.

Description

technical field [0001] The invention relates to the technical field of scroll compressors, in particular to a scroll compressor with an axial magnetic levitation structure. Background technique [0002] At present, the structure of the scroll compressor is as follows: the fixed scroll is at the top, and the movable scroll is at the bottom, relying on the rotation of the crankshaft to drive the movable scroll to move, and mesh with the static scroll to form a closed cavity, and then the compressor gas , the lower part of the movable scroll is supported by the upper support (thrust surface). The movable scroll itself has downward gravity, and the higher pressure generated in the closed scroll compression chamber will make the movable scroll generate greater downward force. Due to the improvement of processing capacity, the displacement and size specifications of scroll compressors are developing in a larger direction. Taking a 50HP compressor as an example, it can generate a ...

Problems solved by technology

This causes the following problems: relative sliding produces relatively large friction force, resulting in large power consumption; due to the large friction force, the reliability is poor, and it is easy to be damaged and deformed; The area of ​​the supporting thrust surface is made larger, which affects the compactness of the compressor structure and hinders the development of large-scale compressors
