Self-cleaning sewage lifting equipment | Sewage lifting equipment

Widely used in underground building locations such as villas, hotels, hospitals, subway stations, and commercial office buildings, covering industries including real estate, **, catering, and transportation. It has solved the sewage discharge issues for over a thousand enterprises and projects.

Process Introduction:

① Provided to customers as a complete system. Users only need to connect the input, output pipelines, and exhaust port of the equipment to the reserved pipelines, connect the power cord, and the equipment can operate normally.

② The tank is made of PE engineering plastic, which is corrosion-resistant. The tank is sealed, with no odor emission.

③ The tank is divided into three zones according to the process: Zone A is the temporary storage area for waste, Zone B is the temporary storage area for sewage, and Zone C is the collection pool. Zone A and Zone B are separated by a filter, while Zone B and Zone C are separated by a partition plate.

④ The filter's function is to trap waste in Zone A while allowing sewage from Zone B to pass through the filter into Zone A. The partition plate completely separates Zone B and Zone C, but they can communicate through the pump flange.

⑤ Domestic sewage enters Zone A through the inlet, where waste is temporarily stored in Zone A by the filter, while the sewage passes through the filter into Zone B. After temporary storage in Zone B, it enters Zone C through the pump flange. Zone C is the collection pool, equipped with a liquid level controller. When the liquid level reaches a certain height, the sewage pump starts working, pressurizing the sewage from the collection pool and sending it to Zone B. The high-pressure water in Zone B passes through the filter into Zone A, forming a vortex of high-pressure water in Zone A. This high-pressure water closes the check valve at the inlet, lifts the waste in Zone A, and discharges it out of the tank through the outlet.

⑥ When the sewage pump is pumping, the water level in the collection tank decreases. When it drops to a certain level, the liquid level controller sends a signal to the pump controller, and the pump stops working. At this point, the sewage lift enters the next work cycle.

Features:

① Divided into three functional zones with very clear purposes, ensuring high reliability of the equipment.

② Waste, suspended solids, and large particles entering from the inlet are only temporarily stored in Zone A and do not pass through the pump. Under the action of high-pressure water, they are directly lifted and discharged out of the tank, preventing clogging of the pump by waste.

③ Sewage and waste are discharged from the pipeline in a swirling state, making the pipeline less prone to clogging.
