Slide sheet and compressor

Abstract

The invention discloses a slide sheet and a compressor. The slide sheet comprises a first surface which is used for being movably matched with a slide groove; a first dynamic pressure part is arrangedon the first surface in an inwardly concave mode; a first decompression part is arranged on the bottom wall of the first dynamic pressure part in an inwardly concave mode; the first dynamic part communicates with the first decompression part; and the slide sheet makes reciprocating motion in the slide groove. Under the shearing action, a fluid medium flows along the first surface of the slide sheet and the design gap between inner walls of the slide groove and flows into the zone of the first dynamic pressure part; the slide sheet is inclined so a difference exists in dimensions of gaps withdifferent parts of the first dynamic part; smaller gaps realizes stronger dynamic pressure effects, and the fluid film bearing capacity is larger, so an acting moment of force is generated on the slide sheet along the thickness direction and is opposite to the direction of inclination; the inclination of the slide sheet slows down, so the loss of the compressor is lowered; and through the arrangement of the first decompression part inside the first dynamic pressure part, the volume of a space inside the first dynamic pressure part can be increased, and the slide sheet is prevented from generating acting force in the thickness direction and causing sudden change.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a sliding vane and a compressor. Background technique [0002] The surface wear of pump body parts is a common failure form of rotary compressors. The energy loss caused by friction and wear between friction pairs accounts for about 10% to 30% of the entire compressor system, resulting in increased input shaft power and reduced energy efficiency of the refrigeration system. [0003] The traditional compressor includes a sliding vane, which is an important friction unit of the compressor. Ideally, a fixed lubricating gap is designed between the side of the sliding vane and the chute, and the sliding vane reciprocates along the direction parallel to the chute. However, when the traditional compressor is actually working, the sliding vane is affected by the high and low pressure in the chambers on both sides, and will be affected by spring force, friction force, support force, i...

AI Technical Summary

Problems solved by technology

[0004] Based on this, in order to solve the problem that when the traditional compressor is in use, the inclination of the sliding vane along the thickness direction forces the side of the sliding vane to collide with the inner wall of the chute, causing friction and wear, which further affects the performance and operation of the compressor. The sliding vane and the compressor can slow down the inclination of the sliding vane when in use, thereby reducing the loss of the compressor
