Abstract

The invention discloses a pure oil-free high-speed compressor based on an air suspension bearing. The compressor comprises a motor, turbines, a pressure adjusting assembly, a cooling assembly and a controller; a radial dynamic pressure bearing and a stator are arranged in the motor, a main shaft is arranged in the motor, the two ends of the main shaft are suspended in the radial dynamic pressure bearing, a radial dynamic pressure groove and a rotor are arranged on the main shaft, the turbines comprise volutes and impellers, the volutes are arranged at the two ends of the motor, air inlet pipes and air outlet pipes are arranged on the volutes, the impellers are arranged in the volutes and connected with the motor, the pressure adjusting assembly is used for adjusting the amount of air entering the air inlet pipes, the cooling assembly is used for conducting heat dissipation treatment on the motor, and the controller is electrically connected with the pressure adjusting assembly and the cooling assembly. The compressor is reasonable in structural design, efficient, energy-saving and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a pure oil-free high-speed compressor based on an air suspension bearing. Background technique [0002] An air compressor is a device used to compress gas. An air compressor is similar in structure to a water pump. Most air compressors are reciprocating piston, rotary vane or rotary screw. Centrifugal compressors are very large applications. There are many types of air compressors, such as: Roots blower, multi-stage centrifugal blower, single-stage centrifugal blower, etc.; a centrifugal compressor is a device that uses centrifugal force to compress gas by rotating the blade wheel in the housing. A centrifugal compressor may be configured to compress a gas, such as a refrigerant gas. In such a centrifugal compressor, when the driving force of the motor is transmitted to the impeller and the impeller rotates, gas is introduced into the impeller by the rotational force of the...
