Schematic diagram of centrifugal pump

First, an overview of centrifugal pumps

1, the pump is to transport liquid and increase the pressure of the machine.

2, the pump is divided into chemical pumps, water pumps.

3, the main differences: special materials and design, to prevent corrosion and adapt to chemical processes, including the structure, shaft seals, materials and maintenance difficult.

4, chemical pump requirements

(1) to adapt to the chemical process requirements and reliable operation.

(2) corrosion resistance, wear resistance.

(3) to meet the no leakage requirements.

(4) high temperature or low temperature and can work continuously.

The structure of centrifugal pump

Mainly include the volute-shaped pump body, pump shaft, impeller, mechanical seals, bearings and gland and other major accessories, in addition to some other accessories did not figure out the figure, such as suction pipe, water pipe, valve, control valves, irrigation Funnel and pump seat and so on.

 

In order to make the centrifugal pump to work properly, the centrifugal pump must be equipped with a certain pipeline and pipe fittings, which is equipped with a certain pipeline system, known as centrifugal pump centrifugal pump. The figure shows the general schematic diagram of the centrifugal pump, there are bottom valve, suction pipe, outlet valve, outlet pipelines and so on.
