A scroll compressor capable of quick depressurization

Abstract

The invention discloses a scroll compressor capable of quickly relieving pressure. An air return groove (4a) is formed in the end surface of a bracket (4), an air return hole (1a) is formed in a static vortex plate (1), and a wear resistant gasket (3) is arranged between the bracket (4) and a dynamic vortex plate (2) and is abutted with the end surface of the bracket (4), so that the air return groove (4a) forms a sealed channel; an air hole (3a) and a pressure relief hole (3b) are formed in the wear resistant gasket (3), one end of the air return hole (1a) communicates with the air return groove (4a) through the air hole (3a), the other end of the air return hole (1a) communicates with a high-pressure chamber of the scroll compressor, and the air return groove (4a) communicates with a low-pressure chamber of the scroll compressor through the pressure relief hole (3b). When the scroll compressor is shut down, the dynamic vortex plate (2) is far from the wear resistant gasket (3), the pressure relief hole (3b) is opened, the high-pressure chamber communicates with the low-pressure chamber, and the system difference pressure is balanced. According to the scroll compressor, the problem of start failure caused by large torque when the scroll compressor is shut down and is restarted at once is solved, and the pressure balance time of the whole system can be shortened to about 10% of the original time.

Description

technical field [0001] The invention belongs to the field of scroll compressors, in particular to a scroll compressor capable of rapid pressure relief. Background technique [0002] The scroll compressor is composed of two double-function equation-shaped dynamic and static scrolls meshing with each other. During the working process of suction, compression and exhaust, the fixed scroll is fixed on the frame, the movable scroll is driven by the crankshaft and restricted by the anti-rotation mechanism, and rotates in a plane with a small radius around the center of the base circle of the fixed scroll. It is sucked into the periphery of the fixed scroll, and with the rotation of the eccentric shaft, the gas is gradually compressed in several crescent-shaped compression chambers formed by the meshing of the fixed and fixed scrolls, and then continuously discharged from the exhaust hole of the central part of the fixed scroll. [0003] When the scroll compressor is working, one s...
