Principle of centrifugal air compressor | Henan Haijie Technology

At present, there are many types of air compressors in the domestic market. The more common ones include screw air compressors, centrifugal air compressors, etc. They are distinguished according to air output, power and other factors. The working principle of the centrifugal air compressor is to work on the gas through the impeller, and convert the mechanical energy into gas pressure energy by using the centrifugal boosting effect and the deceleration and pressure expansion effect in the flow channel of the impeller and diffuser. As we all know, high-quality centrifugal air compressor accessories are the basis for ensuring the normal operation of air compressor equipment. Can you tell whether the accessories selected by the service provider are genuine during after-sales maintenance of the centrifugal air compressor? For example, there are many purchase channels at present, but they are nothing more than two aspects. One is to import directly from abroad, and the other is to purchase air compressor parts from dealers. Air compressor parts are imported directly from foreign complete machine factories and parts supporting factories. The quality is guaranteed. If the air compressor parts are purchased from a dealer or re-exported from Hong Kong and Macao, they must be identified according to the above method. In addition, all air compressor parts imported directly from abroad have order contracts, bills of lading, waybills, packing lists and invoices. If you purchase air compressor parts from an imported company, you can ask them to show the above procedures. Otherwise, it can be judged as non-imported genuine products. There is still a certain gap between my country's industrial production automation level and developed countries. The 12th Five-Year Plan proposes to transform and upgrade the manufacturing industry. Among them, developing advanced equipment and promoting the manufacturing industry from large to strong will guide future development. Frequency conversion technology will be further promoted in the fields of industrial speed regulation and precision control due to its excellent performance. In particular, the future development of low-voltage frequency conversion technology, which is widely used in the manufacturing industry, is closely related to automation transformation and equipment upgrading.
