What's a centrifugal pump? It was created in line with the principle of the centrifugal force. It's a push that uses the high-speed rotating impeller to really make the water move and realize the transportation of the water. Available in the market, there are a lot of centrifugal pumps. 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, transh pump and anti-corrosive pump. Owing to its compact structure, even flow rate, low vibration, stable operation and other features, the centrifugal pump is popular to transport the fluid via a pipeline in different systems, such as cooling system, industrial equipment, aqua farm, fertilization system or cleaning system.
In order to completely learn the working principle with this pump, it is of great necessity to first learn what the centrifugal principle. Simply speaking, the centrifugation happens to be some sort of the inertial performance. Like, when the umbrella slowly turns around, the water drip on the umbrella will also turn around with the umbrella. KSB HDA 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 very quickly, the water drip will get off the umbrella. As the friction force can't make the water drip move around in a circle. This is actually the so-called centrifugation. In the same way its name implies, the centrifugal pump utilizes the centrifugal phenomenon to work.
Now it is 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 features a so quick rotating speed so it can deliver the large power. When it comes to impeller leaves, they plays an essential role in the large power output. The pump body is also named shell. It's the main body of the centrifugal pump. Its main function is to support the entire equipment. As the main element of transmit the mechanical energy, the pump axis is to pass the torque of the electric motor to the impeller. When it comes to bearing, there are two kinds, namely roller bearing and sliding bearing, whose function is to support 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. When it comes to 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.
