Basic principle and maintenance of vertical multistage centrifugal pump, when the suction centrifugal impeller on the shaft of the vertical multistage centrifugal pump motor is running at high speed, the liquid covered in the suction centrifugal impeller under the action of cohesion, from the suction centrifugal impeller management along the overcurrent channel between the blades to the suction centrifugal impeller around, because the liquid is affected by the role of the blade, In addition, the pressure and speed are increased, and the flow path through the guide casing is pulled to the second stage of the suction filter centrifugal impeller, so that the pressure mechanical energy of the liquid is further increased by several times over all the suction filter centrifugal impeller and the guide casing. The leakage, power failure, load and overtemperature of the pump are controlled to ensure the reliability of the vertical centrifugal pump. Dual rail automatic coupling redo system, for the installation of the pump installation, maintenance caused a great convenience, people do not have to enter and exit the sump. Cable cable Cable float switch can be changed according to the required water level line. Automatic automatic control system pump stop and start, without staff care. Ensure motor operation within the power range of the pump. The vertical centrifugal pump is a liquid chemical (acetylene gas and liquid, can also be suspended fine particles and acetylene gas or liquid chemical substances) from the blade rotation shaft root (inlet) into the chemical substances rely on high-speed rotation of the blade to obtain cohesion, resulting in a high pressure, from the pressure relief port (inlet and outlet) discharge of chemical substances transport equipment machine equipment. Vertical centrifugal pump is to have the same effect of more than two pumps together, liquid safety channel structure, specific performance in the first level of chemical substance pressure relief port and the second level of the inlet, the second level of chemical substance pressure relief port and the third level of the inlet, so connected the mechanism caused by the vertical centrifugal pump.

Vertical multistage centrifugal pump product features:

1, the use of hydropower station digital model and production processing technology, to further improve the characteristics of vertical centrifugal pump and service life.

2, because the sealing of the centrifugal pump is made of cemented carbide cutting tool numerical control blade and fluorine rubber mechanical seal, it can improve the efficiency of pump operation and the temperature of transporting chemical substances.

3. Part of the overcurrent flow of the vertical centrifugal pump is welded by arc welding of the stainless steel metal mold, which promotes that the pump can be used to lightly etch chemical substances.

4, the overall structure is compact, small body size, relatively light net weight, low noise, environmental protection and energy saving effect is obvious, maintenance is convenient and fast.

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

6, the use of standard motor, customers can easily and quickly equipped with motor.

7, vertical multistage centrifugal pump can be equipped with intelligent system protection equipment according to customers, the pump dry rotation, phase break, load maintenance.
