Copeland compressor analyzes the current status of centrifugal compressors Copeland compressor is a common compressor brand, and the same Copeland compressor brand can be divided into many types of compressors, such as centrifugal compressors, piston compressors, liquid ring compressors, diaphragm compression Machine etc. The following is introduced by the staff of Copeland compressor dealer d, about the various characteristics and working principles of centrifugal compressors. The main working parts of the centrifugal compressor for compressing gas are the impeller rotating at high speed and the diffuser with increasing flow area. In short, the working principle of the centrifugal compressor is to work the gas through the impeller. In the flow path of the impeller and the diffuser, the centrifugal boosting effect and the deceleration and expansion pressure effect are used to convert the mechanical energy into gas pressure energy. .
More generally speaking, when the gas flows through the impeller of the centrifugal compressor, the impeller rotating at high speed causes the gas to increase the pressure under the action of the centrifugal force, on the other hand, the speed is also greatly increased, that is, the centrifugal compressor The impeller first converts the mechanical energy of the prime mover into the static pressure energy and kinetic energy of the gas. After that, when the gas flows through the channel of the diffuser, the cross section of the flow channel gradually increases, the velocity of the gas molecules in the front decreases, and the gas molecules in the back continuously flow forward, so that most of the kinetic energy of the gas is converted into static pressure energy. That is to further increase the pressure. At present, the international development direction of centrifugal compressors is increasing compressor capacity, new gas seals, magnetic bearings and non-lubricating couplings have emerged in succession; high-pressure and small-flow compressor products continue to emerge; ternary flow theory research is further deepened , Not only applied to the design of the impeller, but also developed into the design of the delicate components of the blade diffuser, the efficiency of the unit has been improved; the use of noise protection technology to improve the operating environment, etc.
