Analysis Of The Main Components Of Sanitary Centrifugal Pumps

Sanitary Centrifugal Pump is a type of single-suction single-stage centrifugal pump, which is a vertical structure. Because its inlet and outlet are on the same straight line and the inlet and outlet diameters are the same, it resembles a section of pipe and can be installed at any position of the pipe, so it is named a sanitary centrifugal pump. Structural features: It is a single-suction single-stage centrifugal pump, with the same inlet and outlet and on the same straight line, perpendicular to the axis centerline, and a vertical pump.

Analysis of the main components of sanitary centrifugal pumps:

1. Motor: The main component that converts electrical energy into mechanical energy

2. Pump seat: It is the main body of the pump and plays a supporting and fixing role

3. Impeller: The core part of the centrifugal pump, it has a high speed and a large output. The blades on the impeller play a major role. The impeller must pass the static balance test before assembly. The inner and outer surfaces of the impeller are required to be smooth to reduce the friction loss of the water flow

Impeller classification:

Open impeller: suitable for conveying materials containing a large amount of suspended matter, with low efficiency and low pressure of the conveyed liquid

Semi-closed impeller: suitable for conveying materials that are easy to precipitate or contain suspended particles such as solid particles and fibers, with low efficiency

Closed impeller: suitable for conveying clean liquids without impurities, with high efficiency

4. Pump shaft: connected to the motor, it is the main component for transmitting mechanical energy

5. Mechanical seal: a device that prevents fluid leakage by maintaining contact and relative sliding
