What's a centrifugal pump? It is designed in line with the principle of the centrifugal force. It is a pump that uses the high-speed rotating impeller to make the water move and realize the transportation of the water. Available in the market, there are always a large amount of centrifugal pumps PWC. On basis of its functions, it could be classified into home pump and industrial pump. In accordance with its pumped medium, it could be separated into clarified water pump, trash pump and anti-corrosive pump. Owing to its compact structure, even flow rate, low vibration, stable operation and other features, the centrifugal pump is trusted to move the fluid through a pipeline in different systems, such as for example cooling system, industrial equipment, aqua farm, fertilization system or cleaning system.

To be able to completely learn the working principle with this pump, it's of great necessity to first learn what the centrifugal principle. Simply speaking, the centrifugation happens to be some sort of the inertial performance. Like, once the umbrella slowly turns around, the water drip on the umbrella will even turnaround with the umbrella. This is due to the centrifugal force, which will be formed by the friction force involving the umbrella and the water drip. However, if the umbrella turns around rapidly, the water drip will get away from the umbrella. As the friction force can not make the water drip move in a circle. This is the so-called centrifugation. Just as its name implies, the centrifugal pump makes use of the centrifugal phenomenon to work.

Now it's turn to introduce the basic structure of a centrifugal pump. It includes six parts, namely impeller, pump body, pump axis, bearing, seal ring and stuffing box. The impeller may be the core component because of this pump. It includes a so quick rotating speed that it can deliver the large power. As for the impeller leaves, they plays an essential role in the large power output. The pump body can also be named shell. It is the key body of the centrifugal pump. Its main function is to guide the complete equipment. As the key element of transmit the mechanical energy, the pump axis is always to pass the torque of the electric motor to the impeller. As for the bearing, you can find two kinds, namely roller bearing and sliding bearing, whose function is to guide the pump axis. The seal ring is installed at the junction involving the inner edge of the shell and the outer edge of the impeller. It plays an essential role in increasing the reflux resistance, reducing the inner leakage and prolonging the operation time. As for the stuffing box, it is composed of stuffing material, water sealing pipe, seal cage and so on. To seal the gap involving the shell and axis is its main function.
