Problems solved by technology

[0002] The Chinese Invention Patent Publication No. CN1100774 named "Engagement Rotor" discloses a rotor. When it is used for gas compression, its pair of self-engaging working teeth and the meshing tooth grooves will produce residual volume at the meshing point. Vacuum cavitation will be generated when passing the meshing point, and the tooth root of each involute tooth will also generate volume residual at the meshing point. Vacuum cavitation will be generated when passing the meshing point, which will cause certain power loss

Embodiment Construction

[0033] The following describes the implementation process of a pair of rotors in the "Chinese rotor gas compressor":

[0034] Let the circular rotor radius R of the main rotor A be a 66 R a =66

[0035] Convex tooth tip circle radius R a1 =R a +R=66+16=82

[0036] Transmission ratio i is 3:2 i=3:2=1.5

[0037] Auxiliary rotor B circular rotor radius R b R b =44

[0038] Groove root circle radius R b1 =R b -R=44-16=28

[0039] Center distance L=R a +R b =66+44=110

[0040] Determine the R of the arc C, let R be 16 R=16

[0041] Let the rotation angle α of the conjugate curve C be 3°

[0042] Let the channel t between the groove on the auxiliary rotor and the compression chamber be 1.5

[0043] And L=(Ra-)+(Rb+)=110

[0044] but

[0045] Ra-=Ra-t=66-1.5=64.5

[0046] Rb+=Rb+t=44+1.5=45.5

[0047] On the secondary rotor B there is O b is the center R b 44 is a point S on the outer circumference of the radius, and the arc C, the conjugate curve E and the rad...

Abstract

The invention provides a Chinese style rotor gas compressor. As for a pair of rotors of the compressor, a convex tooth rotor A is provided with a convex teeth 2 greater than the external circumference of the rotor and each consisting of a conjugate curve and an arc line; a groove rotor B meshed with the double wedge rotor is provided with grooves 1 smaller than the external circumference of the rotor and each consisting of a conjugate curve and arc line. A circular section of external diameter Ra of a main rotor A is designed to be Ra-, and a circular section of external diameter Rb of an auxiliary rotor B is designed to be Rb+; the large and small diameters enable the groove on the auxiliary rotor to communicate with a compression chamber, in order to avoid water (oil) trapping and pulsation caused by unbalanced gas pressure, thereby reducing power loss caused by the above phenomena. In the rotary motion, convex teeth on the rotor 2 play the role of suction and compression, and grooves 1 on the groove rotor play the role of accommodating and transit the convex teeth 2. The Chinese style rotor gas compressor can be used for manufacture of machinery for pumping vacuumization / compressing gas / conveying fluid.

Description

technical field [0001] The present invention relates to a "Chinese-style rotor gas compressor". The main rotor of the gas compressor has a convex tooth with a combination of conjugate curve and arc line obtained by parametric design, and the corresponding auxiliary rotor has parametric design. Obtain the groove combined with the conjugate curve and the arc line, and use the main and auxiliary rotors to manufacture a machine for pumping vacuum / compressing gas and transporting fluid. This kind of machinery can achieve the effect of high volumetric efficiency, low noise and long service life in practical application. Background technique [0002] The Chinese Invention Patent Publication No. CN1100774 named "Engagement Rotor" discloses a rotor. When it is used for gas compression, its pair of self-engaging working teeth and the meshing tooth grooves will produce residual volume at the meshing point. Vacuum cavitation will be generated when passing the meshing point, and the too...
