Abstract

The invention relates to the technical field of scroll compressors and particularly relates to a scroll disc structure and a carbon dioxide compressor. The scroll disc structure comprises a movable scroll disc, a static scroll disc and a sealing ring, wherein the sealing ring is eccentrically arranged in a back pressure cavity; the resultant force F1 of the gas force and the inertia force borne by the movable scroll disc and the back pressure F2 borne by the movable scroll disc are equal in torques and opposite in directions, so that the turning torque of the movable scroll disc and the back pressure torque of the movable scroll disc are balanced.

Description

technical field [0001] The invention relates to the technical field of scroll compressors, in particular to a scroll structure and a carbon dioxide compressor. Background technique [0002] In a scroll compressor, a fixed scroll member and an orbiting scroll member are generally engaged to form a compression chamber between them. When the orbiting scroll rotates along a circular orbit, the compression chamber moves while changing its volume to perform suction, compression, and discharge. By applying a predetermined back pressure to the outer peripheral portion of the orbiting scroll and the back surface of the scroll wrap, the orbiting scroll is prevented from being separated from the fixed scroll and falling over. [0003] During the working process of the compressor, under the joint action of the gas force and inertial force on the movable scroll, an overturning moment will be generated, causing the movable scroll to overturn. This phenomenon will lead to the problem of ...
