Background

An air compressor is a device for compressing gas. The centrifugal compressor is also called as a "vortex-type compressor". The main components of a centrifugal compressor used to compress gas are an impeller rotating at high speed and a diffuser having a gradually increasing flow area. The working principle of the centrifugal compressor is that the impeller works on gas, and in a flow passage of the impeller and the diffuser, mechanical energy is converted into pressure energy of the gas by utilizing the centrifugal boosting effect and the speed reduction and diffusion effect. Centrifugal compressors are widely used in various process flows for conveying air, various process gases or mixtures of gases and for increasing the pressure thereof. Air jet looms are shuttleless looms that use a jet of air to pull the weft yarn through the shed. The working principle is that air is used as a weft insertion medium, the ejected compressed airflow generates friction traction force on weft yarn to pull the weft yarn, the weft yarn is taken through a shed, and the purpose of weft insertion is achieved through jet flow generated by air ejection. Therefore, the air supply of the air jet loom by the centrifugal compressor is needed so as to maintain the normal operation of the air jet loom.

The centrifugal compressor consists of a rotor, a stator, a bearing and the like. The impeller and other parts are sleeved on the main shaft to form a rotor, and the rotor is supported on a bearing and driven by a power machine to rotate at a high speed. The stator comprises a shell, a partition plate, a seal, an air inlet chamber, a volute chamber and the like. Fixing elements such as a diffuser, a bend and a return pipe are formed between the clapboards.
