What Is a Submersible Pump?
A submersible pump is a pump that is submerged in water.
The suction outlet of the pump must be lower than the level of the liquid to be lifted to prevent dry suction. Therefore, a typical industrial pump has its suction outlet at the bottom of a tank or pit.
Submersible pumps are compact and can be easily thrown into the water. Submersible pumps do not require a pre-installed suction outlet and can suck out liquids from inspection ports, etc., and are widely used in industry.
Uses of Submersible Pumps
Submersible pumps are widely used in industry because of their characteristics.
A familiar example is pumps for sewage systems. Sewer systems run through underground pits and must be sealed as much as possible because of the foul odor they emit. Submersible pumps are often used for sewage systems because everything but the power supply wiring can be stored underground.
Also, when pouring foundations at construction sites, rainwater will enter the planned foundation site when it rains. Submersible pumps are highly portable and inexpensive, so they are also used for primary drainage during construction.
Principle of Submersible Pumps
Submersible pumps consist of a casing, an electric power section, and a drive section.
The casing protects and houses the structurally weak parts of the submersible pumps, such as the power section. The underside of the suction port is often lined with metal mesh to prevent large objects from biting into the impeller.
The main component of the power section is the motor. The motor and charging section must be insulated from the casing and liquid and is protected through the casing and sealing material. The main shaft of the motor is connected to the impeller of the submersible pumps, which powers the submersible pumps. The power section may also have an inherent function to protect the submersible pumps and is often equipped with a thermo switch, a mechanism that stops the motor in the event of an overload or leakage of electricity.
The driving parts include the impeller and bearings. The impeller is responsible for carrying the liquid sucked out to the outlet. Bearing parts are generally filled with drive oil to lubricate the drive.
