Submersible sewage pump

Submersible sewage pump is a device especially designed for treating sewage, waste water and liquid containing solid particles. This type of pump is widely applied to municipal works, industrial wastewater treatment, construction site drainage, etc. Professional detailed introduction to submersible sewage pump:

1. Structure and composition

Pump body

-Housing: Usually made of cast iron, stainless steel, and other corrosion-resistant materials, it can resist chemical substances and corrosive liquid in sewage.

-Impeller: Impeller is closed or semi-open in most cases, and can treat sewage containing solid particles to prevent blocking.

-Sealing system: Double mechanical seal or other efficient seal is adopted to prevent sewage entering the motor cavity and thus ensure motor safety.

Motor

-Submersible motor: Motor is integrated with pump body and completely submerged in water to achieve excellent heat dissipation effect and waterproof performance.

-Overload protection: The built-in heat protection device can prevent motor from being overheated or overloaded and thus extend the service life of motor.

Control system

-Liquid level controller: Automatically start and stop the pump and control pump operation according to the change in the water level to save energy.

-Automatic alarm system: Give an alarm timely in the case of faults or abnormalities to ensure safety system operation.

2. Working principle

Submersible sewage pump can produce centrifugal force via revolving impeller to inhale sewage from the inlet and discharge it via the outlet. Since both the pump body and the motor are submerged in water, the pump can work at a deep water level, making it adapt to kinds of complex environments.

3. Advantages and characteristics

High productivity

-High efficiency: Submersible sewage pump is characterized by a compact structure, high energy conversion efficiency and low operation cost.

-Wide application: It can treat sewage containing solid particles, fibers, and suspended solids, showing strong adaptability.

Convenient installation

-Small land area coverage: The pump body and motor are integrated, requiring no additional land space for installation.

-Simple and convenient maintenance: Since the pump body is completely submerged in water, daily maintenance, inspection, and repair are relatively simple.

High reliability

-Corrosion resistance: Made from highly corrosion-resistant materials, it can operate stably for a long time in severe environments.

-High safety: Multiple sealing and protection measures are adopted to prevent sewage leakage and motor damage.

4. Application scenarios

Submersible sewage pump is widely applied to the following fields:

-Municipal works: sewage treatment plants, drainage systems, rain pumping stations, etc.

-Industrial wastewater treatment: Sewage treatment in chemical plants, pharmaceutical factories, food processing factories, etc.

-Construction site: Drainage in basements, tunnels, mine shafts, etc.

-Agricultural irrigation: Treatment and recycling of sewage and wastewater.

5. Installation and maintenance

Installation

-Position selection: The installation position should be convenient for maintenance and inspection, and it should not be installed at a place that is too narrow or not easy to access.

-Fixing measures: A firm base and fixing devices should be used to prevent the pump body from displacing or tilting during operation.

-Electrical connection: It should be ensured that electrical connection conforms to safety standards, to avoid cable damage and electrical accidents.

Maintenance

-Regular inspection: Inspect impeller, sealing element, motor, and control system on a regular basis to ensure all parts work normally.

-Cleaning: The pump body and inlet & outlet should be cleaned on a regular basis to prevent accumulation and blocking of dirt.

-Troubleshooting: Abnormalities in operation should be solved timely to prevent small faults developing into major problems.

Conclusion

Submersible sewage pump plays a big role in sewage treatment and drainage works. Its high productivity, wide application, convenient installation, and high reliability enable it to be a key device in modern sewage treatment system. Through reasonable installation and maintenance, it can be ensured that submersible sewage pump operates stably for a long time to meet the drainage demand in complex environments.
