The basic principle and maintenance of the vertical multistage centrifugal pump. When the suction centrifugal impeller on the shaft driven by the motor of the vertical multistage centrifugal pump runs at high speed, the liquid covered in the suction centrifugal impeller is thrown around the suction centrifugal impeller from the Management Office of the suction centrifugal impeller along the flow passage between the blades under the action of cohesion. Because the liquid is affected by the blades, In addition, the pressure and speed are increased, and the suction centrifugal impeller is pulled to the secondary stage through the passage of the guide shell. In that way, it passes over all the suction centrifugal impellers and guide shells several times to further improve the pressure mechanical energy of the liquid. Control the leakage, power failure, load and overtemperature of the pump to ensure the operation reliability of the vertical centrifugal pump. The double guide rail automatic coupling redo system makes the installation and maintenance of the pump very convenient and fast. People don't have to go in and out of the sewage pit. The cable float switch can change according to the required water level. The automatic control system stops and starts the pump without the care of staff. Ensure that the motor can operate under load within the power range of the operating water pump. The vertical centrifugal pump is a kind of chemical material conveying equipment, in which the circulating chemical substances (acetylene gas and liquid, and also the chemical substances of suspended fine particles and acetylene gas or liquid) enter from the blade rotating shaft root (inlet). The chemical substances obtain cohesion by rotating the blade at high speed, resulting in a high pressure and discharged from the pressure relief outlet (inlet and outlet). The vertical centrifugal pump integrates more than two pumps with the same effect. In the structure of liquid safety channel, the first level chemical material pressure relief port is connected with the second level inlet, and the second level chemical material pressure relief port is connected with the third level inlet. Such a connected mechanism causes the vertical centrifugal pump.

Product characteristics of vertical multistage centrifugal pump:

1. The digital model and production process of hydropower station are adopted to further improve the characteristics and service life of vertical centrifugal pump.

2. Due to the sealing of centrifugal water pump, the raw material is cemented carbide cutter, CNC blade and fluororubber mechanical seal, which can improve the operation efficiency of sewage pump and the temperature of transporting chemicals.

3. Part of the overcurrent of the vertical centrifugal pump is made by arc welding of stainless steel plate and hardware mold, which can promote the pump to be slightly etched with chemicals.

4. Compact overall structure, small size, light net weight, low noise, obvious effect of environmental protection and energy saving, and convenient and fast maintenance.

5. The water inlet and outlet of the vertical multistage centrifugal pump are located in the same straight line of the pump seat and can be used in the pipeline immediately.

6. Using standard motor, customers can easily and quickly equip the motor according to the requirements.

7. The vertical multistage centrifugal pump can be equipped with intelligent system protection equipment according to customers to maintain the dry rotation, phase failure and load of the pump.
