What is the working principle of SH637 submersible drainage pump?

The working principle of SH637 submersible drainage pump is as follows:
1. Motor drive
Power supply:
The submersible drainage pump is connected to an external power supply through a cable to obtain electrical energy. When the power is turned on, the electromagnetic field inside the motor begins to work.
The motor generally uses a three-phase AC motor, and its stator winding will generate a rotating magnetic field.
Motor rotation:
According to the principle of electromagnetic induction, the rotor of the motor begins to rotate under the action of the rotating magnetic field. The rotor is connected to the pump shaft, thereby driving the pump shaft to rotate.
2. Impeller rotation and liquid suction
Impeller structure:
The impeller of SH637 submersible drainage pump is one of its key components. It usually has a specific shape and blade angle design.
The impeller may adopt a multi-blade structure, and the blades are in a certain curved shape.
Liquid suction process:
When the impeller rotates, a local low-pressure area is formed in the center area of ​​the impeller. According to Bernoulli’s principle, under the action of the pressure difference, the surrounding water (or other liquids to be discharged) are sucked into the pump.
The water inlet of the pump is generally designed to be relatively wide to allow water to enter more smoothly. At the same time, it may be equipped with devices such as filters to prevent larger solid impurities from entering the pump and damaging the impeller and other components.
3. Liquid pressurization and discharge
Pressurization process:
As the impeller rotates at high speed, the inhaled liquid gains kinetic energy under the action of the impeller blades.
The liquid is thrown to the outer periphery of the impeller under the centrifugal force of the impeller and enters the pump casing (volute). The shape design of the pump casing makes the flow rate of the liquid in it gradually decrease, while the pressure gradually increases.
This process of converting kinetic energy into pressure energy realizes the pressurization of the liquid.
Discharge process:
The pressurized liquid is discharged through the outlet of the pump. The outlet is usually connected to a drainage pipe to transport the liquid to a designated discharge location or further treatment.
The outlet of the pump may have a specific direction and angle design to meet different installation and drainage requirements.
In short, the SH637 submersible drainage pump drives the impeller to rotate through a motor, and uses the suction and pressurization of the impeller to achieve the function of lifting and discharging low-lying water or other liquids to the desired location, playing an important role in various drainage scenarios.
