Embodiment Construction

[0014] figure 1 The female rotor shown is provided with three grooved profiles 1, figure 2 The shown male rotor is provided with two ribbed profiles 2 . It can be seen from the figure that the concave and convex profiles of the female and male rotors are formed by expanding laterally along the axial direction of the female and male rotors respectively, which are always parallel to the axial direction of the female and male rotors and not along the The direction of the rotor axis is reversed.

[0015] image 3 It is a three-dimensional rendering of a pair of male and female rotors with a ratio of 2 / 3 of the number of rib-type surfaces to the number of groove-type surfaces assembled together according to the relationship of working positions.

[0016] exist Figure 4 In the illustrated embodiment, the figure 1 Shown female rotor 3 with figure 2 Shown male rotor 4, according to image 3 The working position relationship shown is installed and fixed in the "∞"-shaped cyli...

Abstract

The invention relates to a revolving volume compressor, which can be named as arris-bar compressor by the structure characteristic. The invention adopts a group of arris-bar female and male rotors, which are provided with different shapes and are joggled with each other, as the rotating part. a convex profile distributed in symmetry formed by rotor shape is set on the male rotor and a concave profile distributed in symmetry formed by corresponded conjugated rotor shape is set on the female rotor. Convex and concave shapes formed by rotor shape along the same axial direction of male and female rotors are always in parallel with the same axial direction of male and female rotors. Two rotors are supported on infinity-shape cylinder and in corresponded closed cavity comprised by end cover by bearings respectively so as to realize absorption, compression and discharging. The invention is provided with few part numbers, convenience manufacture, good dynamic balance, high reliability, low producing cost and high work efficiency.

Description

technical field [0001] The invention relates to a rotary volumetric compressor widely used in industry and daily life. According to its structural characteristics, it is called a ribbed compressor, which can realize the compression and transportation of fluid. Background technique [0002] At present, positive displacement compressors used in industry and daily life can be divided into reciprocating and rotary compressors. The former are piston compressors, plunger compressors, and diaphragm compressors, and piston compressors are commonly used at present; the latter are rolling piston compressors, Vane type, Wankel type, scroll type, Roots type, screw type compressors, sliding vane type, scroll type and screw type are commonly used at present. [0003] Sliding vane compressors are mainly used in various small compressed fluid devices, refrigeration and air-conditioning devices, and automotive air-conditioning systems. The main disadvantage is that the mechanical friction be...
