Pump body and compressor

Abstract

The invention provides a pump body and a compressor. The pump body includes a cylinder and a sliding vane, the cylinder has a sliding groove, and the two opposite side walls of the sliding groove are a first side wall and a second side wall, wherein the first side wall A plurality of first convex structures are arranged on the wall at intervals along the radial direction of the cylinder, and a plurality of second convex structures, a plurality of first convex structures and a plurality of first convex structures are arranged at intervals along the radial direction of the cylinder on the second side wall. The two protruding structures are arranged in one-to-one correspondence; the sliding piece is slidably arranged in the chute, and the sliding piece is located between the first protruding structure and the second protruding structure. With this solution, due to the provision of the first convex structure and the second convex structure, when the sliding vane reciprocates in the chute, both sides of the sliding vane can form hydrodynamic lubrication, and the oil film pressures on both sides are equal, eliminating the need for It eliminates the unfavorable factor of increasing the contact point pressure caused by the inclination of the traditional sliding vane, and improves the lubrication of the contact point between the sliding vane and the chute, significantly reduces the frictional power consumption of the sliding vane, and improves the reliability.

Description

technical field [0001] The present invention relates to the technical field of compressors, and in particular, to a pump body and a compressor. Background technique [0002] The working chamber of the rolling rotor compressor is surrounded by a cylinder, rollers, sliding vanes and cover plates covering both ends of the cylinder. The rollers are driven by the crankshaft to rotate eccentrically around the center of the cylinder, and the sliding vanes are in the chute of the cylinder. Reciprocating motion, the head of the sliding vane is in contact with the outer wall of the roller, and the crescent-shaped space between the cylinder and the roller is divided into a suction chamber and a compression chamber. communicated with the compression chamber. [0003] Since the gas pressure in the compression chamber is higher than the pressure in the suction chamber, the part of the sliding vane deep into the inner wall of the cylinder bears the pressure difference on both sides, so th...

Problems solved by technology

[0003] Since the gas pressure in the compression chamber is higher than the pressure in the suction chamber, the part of the slide that goes deep into the inner wall of the cylinder bears the pressure difference on both sides, which makes the slide show a microscopic inclined state in the chute, which makes the side of the slide and the chute The contact point is additionally affected by the oil film force on the side of the slide during reciprocating motion, which increases the positive pressure of the contact point, resulting in increased friction power consumption and increased wear on the side of the slide, which restricts the energy efficiency and reliability of the compressor
