Sliding blade and air cylinder together circle center type rotary compressor

Abstract

The invention relates to a rotary compressor with a common center of sliding vane and cylinder, which comprises a circular cylinder body, a first end cover, a second end cover, a rotor and a sliding vane. The cylindrical rotor is eccentrically arranged in the cylinder body, and a section of the outer periphery is in sealing contact with a section of the inner periphery of the cylinder body; the center of one side of the rotor is rigidly connected to the drive shaft, and the other side forms a cavity for accommodating the slide. There is a slide groove on the top; a fixed short shaft is arranged at the center of the second end cover, and the axis of the drive shaft is arranged in parallel with the axis of the short shaft; one end of the slide is rotatably mounted on the short shaft, and the other end passes through the slide The groove, and the radial end surface of the sliding plate and the inner wall of the cylinder maintain an equidistant sliding seal. When the rotor rotates, the sliding vane rotates with it, but the sliding vane always rotates around the axis of the cylinder block, so that the rotor and the sliding vane do not generate reciprocating inertia during work, and the operation is stable; the sliding vane and the cylinder block maintain full surface contact and sealing, so that Minimizes wear and leakage, improving performance of rotary vane compressors.

Description

technical field [0001] The present invention relates to a rotary sliding-vane type fluid machine, and more particularly, to a rotary compressing machine with a common center of a sliding-vane and a cylinder suitable for compressors, pumps and motors. Background technique [0002] Rotary vane compressors (including other sliding vane fluid machinery) have the advantages of simple structure, stable operation and high efficiency, and are widely used in various industries. However, the rotary vane compressor also has some shortcomings, which limit its development, such as: poor low-speed performance, large mechanical wear, increased leakage, and reduced life. The important factor for the formation of the above defects is that the rotor is eccentrically installed in the cylinder, and the rotor is geometrically tangent to the inner surface of the cylinder; and the sliding vane is usually slidably installed on the rotor, and drives the rotor while rotating with the rotor. The slid...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a sliding vane and the cylinder body with a common center of circle for the defects of poor sealing performance, low-speed effect and large wear caused by the linear contact between the above-mentioned sliding vane and the cylinder block in the prior art. rotary compressor
