A magnetic levitation support for a refrigeration compressor

Abstract

The invention discloses a magnetic suspension support of a refrigeration compressor. The magnetic suspension support is used in the field of the refrigeration compressor and comprises an upper magnet arranged on the lower side of a core and a lower magnet arranged on the inner side of a lower shell, the same poles of the upper magnet and the lower magnet are arranged in an opposite way, and the core is suspended above the lower shell. Since the core is suspended above the lower shell due to repulsive force between the same poles of the upper magnet and the lower magnet, the core is completely separated from the lower shell, and the core and a shell are not contacted directly or indirectly through a compression spring, that is, the vibration transmission path is completely blocked, so vibration caused during the operation of the core cannot be transmitted to outside the refrigeration compressor, ideal damping effects can be achieved, finally the safety of external equipment can be protected, and noise pollution can be reduced.

Description

technical field [0001] The invention is used in the field of refrigeration compressors, and in particular relates to a magnetic suspension support for refrigeration compressors. Background technique [0002] Refrigeration compressors mostly use reciprocating compressors. Reciprocating compressors are volumetric compressors, which are compressors that sequentially suck and discharge a certain volume of gas into and out of a closed space. The crankshaft in the compressor drives the connecting rod, the connecting rod drives the piston, and the piston reciprocates. The movement of the piston changes the volume of the working chamber in the cylinder. When the piston moves from the outer dead center to the inner dead center, the intake valve opens and the exhaust valve is closed. The volume of the working chamber increases and the air is sucked in. When the piston When moving to the inner dead center, the intake valve is closed, the intake process is completed, and the volume of ...

Problems solved by technology

However, the compression spring itself is a metal part, and the vibration of the movement can be easily transmitted to the casing through the compression spring body, that is, the transmission path of the vibration is not completely blocked, so the structure of using the compression spring to buffer the vibration of the movement is not perfect The shock absorption effect
