Rotary type displacement compressor

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, there are many types of compressors used in industry and daily life, with different working principles and uses. If divided according to the working principle, it can be divided into two categories: volumetric type and dynamic type; according to the working characteristics of the moving parts or fluid forming the working chamber, it can be divided into reciprocating type, rotary type, centrifugal type, axial flow type, Scroll type and jet type, the first two types belong to volumetric compressors, and the last four types belong to dynamic compressors. Reciprocating compressors in positive displacement compressors are divided into piston type, plunger type, and diaphragm type. ...

AI Technical Summary

Problems solved by technology

[0003] Reciprocating piston compressors are currently in a dominant position in my country's compressor market, but due to their large size, low efficiency, high energy consumption, high noise, low technical performance, and fragile structural parts, they have been listed as Adjustment and elimination objects; sliding vane compressors are mainly used in various small compressed fluid devices, refrigeration and air-conditioning devices and automotive air-conditioning systems, but its main disadvantage is that the mechanical friction between the sliding vanes, rotors, and cylinders is serious, resulting in Short service life and low working efficiency; scroll compressors are more and more widely used in air conditioning and refrigeration industries due to their simple structure, small number of parts, small size, and light weight, but there are parts precision Disadvantages such as high requirements, difficult processing, low exhaust or delivery pressure, and difficult balance of rotating inertial forces; screw compressors are composed of a pair of intermeshing helical rotors, cylinders and bearings, etc., because of their high reliability and dynamic balance. Good, adaptable and widely used in recent years, but it has the disadvantages of difficult processing of the tooth surface of the spiral space, high cost, low exhaust or delivery pressure
