Water pump, as an important equipment for liquid transmission, its working principle and structure have been widely concerned. From the basic structure, the pump is mainly composed of the pump body, impeller, sealing device, etc., they work together to achieve liquid suction, pressure and discharge. When the motor drives the impeller to rotate, the liquid is thrown out under the action of centrifugal force, forming a high pressure, and then realize the liquid transportation.

A deep understanding of the working principle and structure of the pump helps us to better choose and use the pump. Different types of pumps have different working principles and structures, which are suitable for different occasions. For example, centrifugal pumps are suitable for large flow and low head occasions, while plunger pumps are suitable for high pressure and small flow occasions.

With the continuous progress of science and technology, the design and manufacturing technology of the pump is also constantly improving. The new pump not only has higher efficiency and lower energy consumption, but also has stronger corrosion resistance and wear resistance. In the future, with the application of new materials and new processes, the performance and reliability of the pump will be further improved.
