The knowledge of centrifugal pumps is all here!

The basic structure of a centrifugal pump consists of six parts: impeller, pump body, pump shaft, bearings, sealing ring, and packing box.
1. The impeller is the core part of a centrifugal pump, with high rotational speed and high output. The blades on the impeller play a major role, and the impeller needs to undergo static balance experiments before assembly. The inner and outer surfaces of the impeller are required to be smooth to reduce friction losses caused by water flow.
2. The pump body, also known as the pump casing, is the main body of the water pump. Plays a supporting and fixing role, and is connected to the bracket for installing bearings.
3. The function of the pump shaft is to connect the coupling with the electric motor, transmitting the torque of the electric motor to the impeller, so it is the main component for transmitting mechanical energy.
4. The sliding bearing uses transparent oil as a lubricant and is filled to the oil level line. Too much oil will seep out along the pump shaft, and too little bearing will overheat and burn out, causing accidents! During the operation of the water pump, the temperature of the bearings is around 85 degrees, usually around 60 degrees.
