The working principle of well submersible electric pump
2023/06/29
Before using the well submersible electric pump, the suction pipe of the well submersible electric pump and the pump need to be filled with liquid. After the well submersible electric pump starts to run, its impeller is rotating at high speed, and the liquid in it will rotate together with the vanes. Under the action of centrifugal force, the liquid will fly away from the impeller and shoot outward, and the speed inside the pump casing diffusion chamber will gradually decrease, and the pressure inside the pump casing will increase, and then flow out from the discharge pipe of the well submersible electric pump. At this time, in the middle of the vane will be thrown around because of the liquid and the formation of both no air and no liquid vacuum low pressure area. The liquid in the pool is under the action of atmospheric pressure at the surface of the pool, and flows into the pump through the liquid suction pipe of the submersible electric pump. This is the principle of the liquid into the well submersible electric pump, in continuous motion will be pumped up and continuous outflow of liquid.
The basic parameters of submersible pump: including flow rate, head, pump speed, supporting power, rated current, efficiency, outlet pipe diameter, etc.
Well submersible electric pump is composed of control cabinet, submersible cable, head pipe, submersible electric pump and submersible motor. The main uses and scope of application of well submersible electric pump include mine rescue, construction, agricultural drainage and irrigation, industrial water circulation, urban and rural residents cited water supply, and even rescue and disaster relief. In terms of the use of media, well submersible electric pump can be generally divided into three categories: clear water submersible electric pump, sewage submersible electric pump and seawater submersible electric pump (corrosive).

The basic components of a centrifugal pump are a high-speed rotating impeller and a fixed worm-shaped pump casing. Usually centrifugal pumps have a number of (usually 4-12) backward curved vane impeller fastened to the pump shaft, and with the pump shaft driven by the motor for high-speed rotation.

After the centrifugal pump starts, the pump shaft will drive the impeller together for high-speed rotational movement, forcing the pre-filled liquid between the blades to rotate, under the action of inertia centrifugal force, the liquid from the center of the impeller to the periphery for radial movement.

There are many types of centrifugal pumps, and the common classification methods are as follows:
