What are the main pump parts of commonly used centrifugal pumps?

Oct 11, 2018

From the perspective of the construction of the centrifugal pump, it mainly contains five major accessories. Do you know what these pump accessories are? The first is the motor, which is also the main component that converts electrical energy into mechanical energy. Next is the pump base, which is the main body of the pump and acts as a support for fixing.

 

The impeller of the pump fitting is the core part of the centrifugal pump. During the operation of the centrifugal pump, the impeller will run at a high speed and the output is large. The blades on the impeller play a major role, and the impeller passes static equilibrium experiments before assembly. The inner and outer surfaces of the impeller are required to be smooth to reduce the frictional loss of water flow.

 

At present, in the pump, due to the different structural design, the impeller structure of the pump fittings configured is also different. The open impeller is suitable for conveying materials containing a large amount of suspended matter, and the efficiency is low, and the liquid pressure delivered is not high. The semi-closed impeller is suitable for conveying materials which are easy to precipitate or contain particles containing suspended solids such as solid particles and fibers, and the efficiency is also low. The closed impeller is suitable for conveying clean liquid without impurities and has high efficiency.https://www.pump-casting.com/
