Curved sliding vane type rotary compressor

Abstract

The invention relates to a curved slide vane rotating compressor, comprising a circular cylinder body, a first end cap, a second end cap, a circular rotor, and at least one slide vane. The radial inner end face of the cylinder body is a ring-shaped curved face, and is respectively and smoothly connected with axial inner walls of the first and the second end caps. The radial outer end face of the rotor is a curved face which is hermetically engaged with the radial inner end face of the cylinder body, and is respectively and smoothly connected with the axial end faces on the two sides of the rotor. The radial outer end face of the slide vane is a curved face which is hermetically engaged with the radial inner end face of the cylinder body, and is respectively and smoothly connected with the axial end faces on the two sides of the slide vane. The axial end faces on the two sides of the rotor are respectively and hermetically engaged with the inner walls of the first and the second end caps, and the axial end faces on the two sides of the slide vane are respectively and hermetically engaged with the axial inner walls of the first and the second end caps. The invention removes a connecting edge angle, and the working face of a sealing element such as the slide vane, the rotor and the cylinder body is excessively smoothed, which has the advantages of favorable low speed performance, small machinery damage, less leakage, and long service life and the like.

Description

technical field [0001] The invention relates to a rotary vane type fluid machine, more specifically, a curved vane type rotary compression machine suitable for compressors, pumps and motors. Background technique [0002] Rotary vane compressors (including other vane fluid machines) 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 disadvantages, which limit its development, such as poor low-speed performance, large mechanical wear, increased leakage, and reduced service life. The important factors that form the above defects are: [0003] 1. The radial and axial working end faces of the cylinder block, rotor and sliding vane of the sliding vane compressor are generally connected at right angles, which causes difficulties in the smoothness of the sealing parts, causing serious wear at the chamfers, and the amount of leakage increase. The most widely us...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the radial and axial working end faces of the cylinder block, rotor and sliding vane in the prior art are generally connected at right angles, which makes it difficult for the smoothness of the sealing parts and causes chamfering. The defects of severe wear and increased leakage, provide a curved sliding vane rotary compressor with a smooth transition between the radial and axial working end faces of the cylinder block, rotor and sliding vane, and its sealing effect is close to that of the reciprocating piston structure
