Working principle of water pump

I. Working principle of gear pump.

The teeth of the two gears are separated, resulting in a decrease in pressure. Water is sucked in and migrates to the other side along the shell wall. On the other hand, the combination of two gears generates high pressure and the fluid flows out. Gear water pump has less limitations, can meet diverse needs, and is relatively simple to operate, and can be customized according to different needs.

Second, the working principle of centrifugal pump.

When the centrifugal pump is running, water is sprayed from the nozzle of the pump. Produce high-speed rotation. The fluid works continuously under the action of centrifugal force. The internal liquid is transferred to the outside to generate energy. Relatively speaking, it is more functional.

Third, the working principle of multistage centrifugal pump.

The difference between multistage centrifugal pumps is that multistage pumps have more machines than single-stage pumps. The compressor absorbs water and gradually pressurizes, and the water level is high. The steps of the elevator pump valve can be increased or decreased as needed. Centrifugal pumps are vertical and horizontal. Inserting two or more valves in series on the pipeline shaft of multifunctional cylindrical pump can provide higher lift than traditional fixed spray pump.

water pump

A water pump is a machine that transports or pressurizes liquid. It transfers the mechanical energy or other external energy of the prime mover to the liquid, which increases the energy of the liquid. Mainly used for conveying liquids, including water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal. It can also transport liquids, gas mixtures and liquids containing suspended solids.

The technical parameters of pump performance include flow, suction, lift, shaft power, hydraulic power and efficiency. According to different working principles, it can be divided into positive displacement pump and vane pump. The displacement pump uses the change of its working chamber volume to transfer energy; Vane pumps use the interaction between rotating blades and water to transfer energy, including centrifugal pumps, axial pumps and mixed-flow pumps.
