The working principle of the submersible pump is briefly described as follows: The submersible pump rotates through a motor that drives the impeller to generate centrifugal force to draw water into the pump.The pump body is sealed, the motor is immersed in water, and the water flow is driven through the pump shaft.After the motor is energized, a magnetic field is generated to drive the rotor to rotate, which in turn drives the blade to rotate to produce suction, which lifts and drains the water.It is characterized by compact structure, easy operation, high efficiency and energy saving.It is widely used in the drainage and water intake of pools, reservoirs, wells and other places.The working principle of the submersible pump is based on the principles of fluid dynamics and electromagnetism to ensure the safe operation of the motor while achieving efficient pumping.
