A sewage pump with a float switch is a drainage device that integrates liquid level control function. It is a type of pump equipment widely used in sewage treatment, drainage systems, basements, construction sites, municipal engineering and other occasions. It combines the functions of a sewage pump and a float switch, which can automatically start and stop according to changes in liquid level, achieving efficient and intelligent drainage operations. Ensure that the pump automatically starts for drainage when the liquid level reaches a certain height, and stops automatically when the liquid level drops, effectively preventing overflow or equipment from running dry.
Sewage Pump Basic Structure And Working Principle
A sewage pump is a type of pump equipment specifically designed to transport sewage containing solid particles, fibers, or other impurities. Its main structure includes pump body, impeller, motor, sealing device, and float switch.
Pump body: The pump body is the main casing of a sewage pump, usually made of cast iron, stainless steel, or engineering plastic, with strong corrosion resistance and wear resistance, and can adapt to harsh working environments.
Impeller: The impeller is the core component of a sewage pump, responsible for converting the mechanical energy of the motor into the kinetic energy of the liquid. The impeller of a sewage pump is usually designed as an open or semi open type to facilitate the treatment of sewage containing solid particles and prevent blockage.
Motor: The motor provides power for the sewage pump and is usually designed to be waterproof, capable of working normally in damp or even flooded environments.
Sealing device: In order to prevent sewage from infiltrating the motor, sewage pumps are usually equipped with mechanical seals or oil seals to ensure long-term stable operation of the pump.
Float switch: Float switch is a key component of sewage pump with float switch, which controls the start and stop of the pump through the buoyancy of the float. When the liquid level rises, the float rises accordingly, triggering the switch and starting the pump for drainage; When the liquid level drops, the float drops, the switch opens, and the pump stops working.
2、 Working principle of float switch
Float switch is a liquid level control device, usually composed of float, cable, switch mechanism, and heavy hammer. The float is equipped with magnetic materials inside. When the float floats up and down with the liquid level, the magnetic materials will trigger the switch mechanism, thereby controlling the on/off of the circuit.
Floating ball: Floating balls are usually made of plastic or stainless steel, with a hollow interior, and can float on the surface of liquids. The buoyancy of a floating ball allows it to move up and down with changes in liquid level.
Cable: Cable connects the float and switch mechanism, usually with waterproof and corrosion-resistant characteristics to adapt to sewage environments.
Switch mechanism: The switch mechanism is the core part of a float switch, usually composed of a magnetic switch and a mechanical device. When the floating ball rises to a certain height, the magnetic material triggers the switch, the circuit is turned on, and the pump starts; When the float drops to a certain height, the switch is turned off and the pump stops.
Heavy hammer: The heavy hammer is used to adjust the sensitivity of the float switch, ensuring that the float can accurately trigger the switch within the set liquid level range.
