Whirlpool dish for whirlpool compressor

Abstract

Mediates the compressor the vortex plate, in moves, on the static vortex plate separately has two each one independent vortex line tooth. Four vortex line teeth mutually mesh form four independent crescent moons shapes compression cavity, the gas divide into four groups from the air inlet to enter four to be near air cavity carry on the compression, finally compiles, by identical air vent discharging machine outside. This invention under the same vortex plate external dimensions and the same main axle rotational speed, has increased air input, increased the vortex plate center section spatial use factor, reduced the crank radius of gyration, reduced has moved, the static vortex plate relative movement line speed, caused to move the vortex plate stress to be even, reduced the entire machine vibration.

Description

technical field [0001] The invention relates to a fluid variable displacement mechanical device, which is a scroll disk of a scroll compressor, and is suitable for occasions where the exhaust volume is relatively large and the required compression ratio of the gas is relatively small. Background technique [0002] The more common scroll compressors in the prior art are single-head scroll-shaped wire teeth. This scroll compressor has a disadvantage when dealing with a relatively large displacement and a relatively small compression ratio for gas. The following disadvantages: 1) The size of the dynamic and static scroll is large, and the overall size of the whole machine increases; 2) The utilization rate of the center of the scroll is low, and the axial force on the scroll is large; 3) The crankshaft As the radius of gyration increases, the relative motion linear velocity of the dynamic and static vortex increases, the friction force of the dynamic and static vortex teeth inc...

[0002] The more common scroll compressors in the prior art are single-head scroll-shaped wire teeth. This scroll compressor has a disadvantage when dealing with a relatively large displacement and a relatively small compression ratio for gas. The following disadvantages: 1) The size of the dynamic and static scroll is large, and the overall size of the whole machine increases; 2) The utilization rate of the center of the scroll is low, and the axial force on the scroll is large; 3) The crankshaft The radius of gyration increases, the relative motion linear velocity of the dynamic and static vortex increases, the friction force of the dynamic and static vortex teeth increases, the heat generated by friction increases, and the efficiency loss increases.
