The main body of the stator is a casing (cylinder), and the stator is also provided with a diffuser, a bend, a reflux device, a jet pipe, an exhaust pipe, a part of shaft seal and the like. The centrifugal compressor has the working principle that when the impeller rotates at high speed, gas is thrown into the diffuser behind the impeller under the action of centrifugal force along with the rotation of the impeller, a vacuum zone is formed at the impeller, and at the moment, external fresh gas enters the impeller. The impeller is continuously rotated and gas is continuously sucked and thrown out, thereby maintaining continuous flow of gas. Centrifugal air compressors rely on changes in kinetic energy to increase the pressure of the gas. When the rotor with blades (i.e. the running wheel) rotates, the blades drive the gas to rotate, and the work is transferred to the gas, so that the gas obtains kinetic energy. After entering the stator part, the speed energy pressure head is converted into required pressure due to the diffusion action of the stator, the speed is reduced, the pressure is increased, and meanwhile, the pressure enters the next-stage impeller to be continuously increased by the guiding action of the stator part, and finally, the pressure is discharged from the volute.
