Introduction to the water pump
A water pump is a machine that transports or pressurizes liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal, etc. It can also transport liquid and gas mixtures and liquids containing suspended solids. The purpose of the water pump The technical parameters that measure the performance of the pump include flow rate, suction lift, head, shaft power, water power, efficiency, etc. Different pumps have different uses, and their materials, structural forms, conveying liquid media, flow rates, and lift ranges are of course different. To sum up, the purpose of the water pump can be roughly divided into: 1. Urban water supply 2, sewage system 3, civil engineering, building system 4, agricultural water conservancy system 5, power station system 6, chemical system 7, petroleum industry system 8, mining and metallurgy system 9, light industry system 10, ship system How the water pump works According to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pump uses the change of its working chamber volume to transfer energy; vane pump uses the interaction between rotating blades and water to transfer energy, including centrifugal pump, axial flow pump and mixed flow pump.
