Motor Pumps is a pump driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor, and a starting protection device. The pump body is the working part of the submersible pump. It is composed of a water inlet pipe, diversion shell, check valve, pump shaft, and impeller. There are two ways to fix the impeller on the shaft.
The impeller is installed in the pump casing and fastened to the pump shaft, which is directly driven by the motor. There is a liquid suction pipe in the center of the pump housing. The liquid enters the pump through the bottom valve and the suction pipe. The liquid discharge port on the pump casing is connected with the discharge pipe.
Before the pump is started, the pump casing is filled with the liquid to be transported; after starting, the impeller is driven by the shaft to rotate at a high speed, and the liquid between the blades must also rotate with it. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy. It leaves the outer edge of the impeller at a high speed and enters the volute pump casing. In the volute, the liquid is decelerated due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipe at a higher pressure and is sent to the place where it is needed. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Because the pressure above the liquid level of the storage tank is greater than the pressure at the inlet of the pump, the liquid is continuously pressed into the impeller. It can be seen that as long as the impeller rotates continuously, the liquid will be continuously sucked and discharged.
Electric Plunger Pump uses the motor as the power source and relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil absorption and pressure. The product is used in various hydraulic systems. The advantage that distinguishes the gasoline plunger pump is that the use of electric energy is more environmentally friendly and the operation is simpler
