What Is The Working Principle Of Stainless Steel Sewage Elevator

Dec 16, 2025

Stainless steel sewage elevator, intelligent sewage lifting device. A healthy living environment is definitely a clean and hygienic living space. After the household sewage elevator quickly discharges the sewage, it will not remain in the room, creating a more powerful and healthy living environment for daily life.

At the same time, the internal sealing of the sewage elevator is good, and there will be no odor emitted, effectively ensuring the air quality of the living space. Stainless steel sewage elevator, intelligent sewage lifting device. With the sewage elevator, healthy living in the basement has become possible. The successful development and promotion of sewage elevators have solved many drawbacks of existing underground building sewage discharge facilities. This series of equipment achieves closed discharge of sewage and solves the secondary pollution during underground building sewage discharge. The use of sewage and debris separation technology enables the entire equipment to operate without cleaning, and the series of equipment also has the advantage of low maintenance rate.

 

Ⅰ Product features of sewage elevator device:

1. The fully enclosed 304 stainless steel box design ensures that the equipment has no odor leakage and a long service life;
2. Adopting a unique solid-liquid separation device to automatically separate impurities from sewage, reduce blockages, and extend the service life of the water pump;

 

3. Unique one-way check design, limited prevention of sewage and dirt backflow, ensuring the safety of equipment operation. And there is a unique anti backflow device to ensure that even if the one-way check valve fails, there will be no backflow of sewage;
4. Unique backwash device effectively flushes the box at any time, ensuring that the inside of the box remains clean at all times;
5. Intelligent control, unmanned operation.

 

To understand the working principle of a sewage elevator, it is necessary to first understand its composition. The main components of the sewage elevator include the water collection tank, sewage pump, liquid level automation control cabinet, check valve, sealing ring, and controller. The function of a water collection tank is to collect and temporarily store wastewater discharged by users; The function of a sewage pump is to grind and cut impurities in wastewater; The function of the liquid level automation control cabinet is to control the start and stop of the sewage pump; Check valves can prevent sewage from flowing back; The sealing ring can prevent wastewater and odor leakage. By understanding these parts and basic functions, we have a clear understanding of their working principles.

When users discharge sewage, the sewage will enter the collection tank of the sewage lifting pipe along the pipeline. When the collection tank collects wastewater to a certain level, the level automation control cabinet will feedback the signal to the controller. After receiving the signal, the automation control cabinet will start the sewage pump and start working.

When the liquid in the collection tank is discharged below the controlled liquid level, the liquid level control cabinet also sends a signal to the automation control cabinet, and the controller controls the sewage pump to stop, and the sewage elevator enters standby mode again.

The sewage hoist completes the sewage discharge process through the close cooperation of various components.

 

II Working principle of sewage elevator device:

1. The sewage enters the water distributor through the water pipe and flows into the solid-liquid separation device. Solid debris stays in the device, and the sewage enters the water tank.
2. When the sewage in the tank reaches the set liquid level, one of the sewage pumps will be automatically started. The backwash device will discharge the sewage and sludge in the water tank together to the solid-liquid separation device, and flush the solid debris remaining in the device into the discharge pipeline to the sewage pipe network.
When a single pump is started, the pressure in the solid-liquid separation device closes the valve of the inlet pipeline, and the water distributor flushes the sewage from another pipeline into the water tank to ensure the continuity of sewage discharge and lifting.
4. Equipped with special safety devices to ensure that even if the check valve fails, there will be no backflow of sewage.
