The pump is used to pump water, which is driven by the motor to produce pressure water, and the water is transported to a certain height. The pump we usually say generally refers to the pump, which uses the rotating impeller to convert the energy of the fluid into kinetic energy, and the kinetic energy is transferred to the water column in the pump, so as to raise the water to a certain height, and then the water is discharged.
Pumps are widely used in our daily life, such as we use water to wash vegetables to cook, or family water to bathe and so on. Do you know how it works?
First, the pump consists of an impeller, a bearing, a shaft and a sealing ring. The impeller transfers the energy of the fluid to the shaft, which drives the impeller to rotate, and the liquid between the impeller and the pump shell is thrown out due to centrifugal force. The liquid between the blades is at rest because there is no rotating force. After the pump shell leads the liquid into the pump chamber, the liquid flows into the outlet pipe and the discharge pipe through the sealing ring. The outlet pipe is connected to the water pipe.
Look at how the pump works.
The pump is driven by the motor, the motor drives the main shaft to rotate, the main shaft is installed with bearings and sealing rings, sealing rings are fixed on the shaft, when the motor starts, the rotor begins to rotate; After rotating the rotor for one week, water with certain pressure will be discharged from the pump outlet pipe on the journal; When the motor stops, the water without pressure on the shaft will be thrown out; When the water is thrown out, it goes into the pump casing. So the pump can pump the water up to a certain height and out.
When the pump is working, it needs to consume electric energy to drive the bearing and the shaft sleeve to rotate and generate rotating centrifugal force to achieve the purpose of pumping water. In order to provide enough centrifugal force to lift the water to a certain height, the water needs to be pressurized. There are many ways to pressurize, such as pressure pumps, axial flow pumps and so on. One of the most familiar is the centrifugal pump.
