Movable scroll plate assembly, scroll compressor and air conditioning system

Abstract

The invention discloses a movable scroll plate assembly, a scroll compressor and an air conditioning system. The movable scroll plate assembly comprises a movable scroll plate and a counterweight member, wherein the movable scroll plate is provided with a first mass center and a first geometric center, the first geometric center is used as a reference point, and the first mass center is arranged at one side of the first geometric center; and the counterweight member is fixedly arranged on the movable scroll plate and comprises a counterweight section, and the counterweight section is arrangedat the other side opposite to the first mass center so that a second geometric center and a second mass center in an integral structure formed by the movable scroll plate and the counterweight membercan coincide with each other. In a using process for the movable scroll plate assembly, the scroll compressor and the air conditioning system, on the premise that the strength of the movable scroll plate is guaranteed, the running reliability of the compressor cannot be affected by the action of a centrifugal force.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a movable scroll assembly, a scroll compressor and an air conditioning system. Background technique [0002] The scroll compressor relies on the periodic engagement of the movable and static scrolls to compress the refrigerant, compressing the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant and discharging it from the exhaust port. The orbiting scroll usually includes two parts, the base plate and the scroll tooth. The base plate is circular, and the projection of its center of mass on the plane is at its geometric center; the scroll tooth is spiral, and its projection of the center of mass does not coincide with the geometric center, so that the whole The center of mass of the orbiting scroll is offset. When the center of mass of the movable scroll deviates, the distance from the center of mass to the center of the main sha...

AI Technical Summary

Problems solved by technology

[0004]Based on this, aiming at the problem that the strength of the movable scroll of the traditional scroll compressor is low in the process of use, and the reliability of the compressor cannot be guaranteed, it is proposed An orbiting scroll assembly, a scroll compressor and an air-conditioning system are developed. During use of the orbiting scroll assembly, scroll compressor and air-conditioning system, the compressor will not Because the effect of centrifugal force affects the operation reliability of the compressor
