Problems solved by technology

This is especially when studying multi-segment combination curves as the cylinder profile, which will lead to the actual kinematics curve being not smooth, which will increase the wear and leakage of the compressor, so the profile obtained in the study is difficult to apply in actual engineering design

Abstract

The invention discloses a rotary vane compressor and relates to a rotary vane compressor for a vehicle air conditioner, in particular to a rotary vane compressor for an air conditioner on a sedan car, an SUV, a mini bus and a light / heavy truck. The compressor comprises a cylinder body, a rotor, vanes, a front end cover and a back end cover, wherein symmetrical working cavities are formed by the center line of the cylinder body and the contour in the cylinder body; and on any cross section of each working cavity, a first circular arc section contour, a first vane extension section contour, a second circular arc section contour, a first vane constriction section contour, a third circular arc section contour, a fourth circular arc section contour, a second vane extension section contour, a fifth circular arc section contour, a second vane constriction section contour and a sixth circular arc section contour are sequentially distributed along the contour of a rotor angle of 0-360 degrees in the counterclockwise direction, and the tail end of each section contour form smooth connection with the head end of the adjacent contour. The compressor increases the displacement, improves the compression efficiency and the volume efficiency, ensures that the moving speed and acceleration of the vanes are not subject to sudden change, realizes that the vanes do not impact the cylinder body and simultaneously improves the sealability between the cylinder body and the rotor.

Description

technical field [0001] The invention relates to a rotary vane compressor for automobile air conditioners, in particular to air conditioner compressors for cars, SUVs, minibuses and light-duty trucks. Background technique [0002] In order to reduce the leakage between the rotor and the cylinder at the minimum diameter of the cylinder of the automobile air-conditioning compressor and obtain the maximum volumetric efficiency, scholars from various countries have done a lot of work in the research of cylinder profile, and proposed multiple function profile, trigonometric Functional curves and multi-segment combination curves, etc. Guo Bei, Li Liansheng, and Shu Pengcheng analyzed the dynamic characteristics of elliptic curves, cubic curves, and simple harmonic curves as cylinder profiles, and showed that the simple harmonic curve profiles have good speed and acceleration characteristics. The simple harmonic curve is widely used as the cylinder profile, although its profile has...
