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.

 

离心泵的五大部件相互协作

 

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.

1. Pump shaft

The pump shaft is the main shaft of the centrifugal pump, which is used to transmit the power generated when the impeller rotates. Usually made of stainless steel or carbon steel, with high strength and corrosion resistance.

2. Bearing

Bearing is used to support the shaft, can reduce the friction in the movement of the shaft. The bearings in centrifugal pumps are usually ball shafts or sliding bearings, which have good wear resistance and life.

3. Pump casing

The pump casing is the outer casing of a centrifugal pump, usually cast or pressed. The main function of the pump casing is to guide the liquid to the impeller, while supporting the various parts of the centrifugal pump to ensure the normal operation of the centrifugal pump.

4. Impeller

The impeller is the core component of the centrifugal pump, and it is also the key component to generate centrifugal force in the pump. The impeller is usually composed of a plurality of curved blades, and the body is put into the pump by the rotation of the blades, and the liquid is thrown out of the pump by means of high-speed rotation.

5. Seals

The sealing parts in centrifugal pumps are mainly used to avoid internal liquid leakage, including mechanical packing seals. The mechanical seal uses two rotating sealing rings to isolate the liquid in the pump, and the filling prevents the liquid from leaking.

The five components of the centrifugal pump cooperate with each other to complete the liquid transmission. Understanding the structure and function of these components will help to better manage and maintain the centrifugal pump and ensure the normal operation of the centrifugal pump. In addition to industrial applications, centrifugal pumps are also widely used in agricultural irrigation, municipal water supply, power station circulating water supply, urban pollution treatment and so on.
