Composition of Centrifugal Compressor for Shangchai Diesel Generator

Oct. 11, 2022

The centrifugal compressor used by Shangchai diesel generator is composed of inlet, impeller, vaneless diffuser, volute and other components. With the application of new structure energy and the continuous improvement of working efficiency and pressurization ratio, its application scope is wider. Now Starlight Power will share its composition principle.

When the compressor rotates, air enters the compressor impeller through the inlet port and flows from the center of the impeller to the periphery of the impeller along the flow channel formed between compressor blades under the action of centrifugal force. The air gets energy from the rotating impeller, making its flow rate, pressure and temperature increase greatly, and then enters the vane diffuser.

The diffuser is an involute flow passage. When air flows through the diffuser, it decelerates and pressurizes, and the temperature also increases. That is, in the diffuser, most of the kinetic energy of air is converted into pressure energy.

There are two types of diffuser: vaneless and vaneless. Vaneless diffuser is actually an annular space formed by volute and intermediate side wall. The vaneless diffuser has a simple structure, and the change of operating conditions has little effect on the compressor efficiency, so it is suitable for vehicle turbochargers.

Vane type diffuser is a flow passage composed of adjacent blades. Its diffuser ratio is large and its efficiency is high, but its structure is complex. Changes in operating conditions have a greater impact on compressor efficiency. The role of the volute is to collect the air from the diffuser and guide it to the compressor outlet. The air continues to decelerate and pressurize in the volute, completing the transformation from kinetic energy to pressure energy.

The centrifugal compressor used in Shangchai diesel generator has the advantages of small size and high pressurization ratio, and has been widely used in the power system of shipbuilding, aviation and other industries. However, it should be noted that although the speed of centrifugal compressor is high, its efficiency will be slightly lower, and it is only applicable to small and medium-sized production.
