There are several types of water pumps according to the working principle and structure

A water pump is a mechanical device used to move liquid from one place to another. They are widely used in various fields, such as construction, agriculture, industry and household use. According to its working principle and structure, water pumps can be divided into the following types.

The working process and working principle of centrifugal pump

Centrifugal pump at work, relying on high-speed rotation of the impeller, the liquid in the inertial centrifugal force to obtain energy to increase the pressure. Before the centrifugal pump works, the pump body and the inlet pipeline must be filled with liquid medium to prevent cavitation.

The five components of the centrifugal pump cooperate with each other

Centrifugal pumps are the most widely used in chemical production. This is because of their wide range of performance (including flow, pressure head and loss of welcome to the nature of the medium), small size, simple structure, easy operation, uniform flow, long life, Outstanding advantages such as low purchase and operating costs.

Some common problems and solutions of centrifugal pump

The structure of centrifugal pump can basically be divided into horizontal centrifugal pump and vertical centrifugal pump according to the position of the shaft. At the same time, according to the pressure chamber type and suction mode, it can be divided into volute type and guide vane type. Centrifugal pump is relatively simple, mainly composed of four parts: the prime mover, impeller, pump shell and shaft seal device.

How to disassemble vertical multistage pump and matters needing attention

The vertical multistage pump is directly connected with the pump shaft through a coupling. The pull rod bolts fix the pressure barrel and the flow-through parts between the pump head and the inlet and outlet of the pump. The inlet and outlet of the pump are on the same straight line at the bottom of the pump. The intelligent protector can effectively protect the dry rotation, phase loss and overload of the multistage pump according to the needs. Vertical multistage centrifugal pump can be applied to a variety of different media of industrial liquid, below to explain the vertical Dalian multistage pump disassembly and matters needing attention.

What are the structural characteristics and advantages of multi-stage pumps

The difference between multi-stage pump and single-stage pump is that it has more than 2 impellers and its head is changeable. For example, the head of some horizontal multi-stage pumps has a minimum of 75 meters and a maximum of 685 meters. A multistage pump is a complex of two or more single-stage pumps. The single-stage pump is easy to operate, relatively stable in performance, small in size and light in weight, so it is easy to handle. The degree of integration of Dalian multi-stage pump is high, but the operation is complex and the maintenance is difficult.
