The sewage elevator can mainly be used for the drainage of sanitary ware sewage in basements and places far away from the drainage riser where there is no self discharge of sewage. It can also be used in situations where the drainage conditions are not good for ships, vehicles, etc. It is composed of a rubber colloid water storage bag, a crushing and cutting pump, a check valve, and the inlet and outlet of sewage.
　　It can mainly be used for the drainage of sanitary ware sewage in basements and places far away from drainage risers where there is no self discharge of sewage. It can also be used in situations where drainage conditions are not good, such as ships and vehicles. It is composed of a rubber colloid water storage bag, a crushing and cutting pump, a check valve, and the inlet and outlet of sewage. The start and stop of its cutting pump are not based on the liquid level, but rather transmit the changes in pressure inside the pressure sensing pore to the pressure sensor. Once sewage enters the water storage bag, the air inside the pressure sensing pore is compressed. As the water volume inside the bag increases, the pressure also increases, driving the start and stop of the cutting pump. Due to the crushing function of the cutting pump, it can crush feces, toilet paper, or body matter brought in by kitchen washing that is discharged into the bag with sewage, thus completely avoiding blockage.
　　Most basements in villa areas are equipped with villa type elevators. Currently, in most ordinary residential buildings, real estate companies also design basements to increase their usage area. At first, the drainage of basements in China was designed as a cement brick sump in the basement, where bathroom sewage, bathroom sewage, and washbasin sewage were discharged into the sump through pipes on the same floor. Two Submersible pump are installed in the water pit, which is what we usually call "one pit, two pumps" underground sewage discharge mode. The alternating operation of two pumps ensures the reliability of sewage discharge. But the biggest drawback of this working method is that it requires regular cleaning and odors. The basement itself has no windows, and odors cannot be eliminated. The odor makes the basement unusable. And regular cleaning is also a fatal drawback of this underground drainage method.
　　Later, with the introduction of sewage elevators from abroad to China, this "one pit, two pumps" basement drainage method was gradually replaced by elevators. The characteristics of this villa type sewage elevator are odorless and free from cleaning. However, due to its small capacity, the frequent start-up of the water pump has made its reliability a challenge. Most elevators work by placing a single-phase water pump inside a small container. The control of the small water pump is controlled by an air pressure switch, and the drainage of toilets, washbasins, bathrooms, etc. in the basement flows into the box. Then, the water pump inside the elevator lifts the sewage out of the room.
1. PE material: durable, crack resistant, environmentally friendly, and with a long service life
3. No backflow of sewage: Due to the use of double check valves in the inlet pipe, the possibility of sewage backflow is enhanced.
5. Reliable monitoring of sewage tank water level: The water level monitoring control is sensitive, ensuring the reliability of water pump start and stop.
6. Non pollution: Sewage is stored and discharged in a sealed manner, without spillage or odor, protecting the surrounding environment.
　Advantages:
1. Completely sealed, no odor emitted;
2. Silent operation;
3. Convenient connection with multiple water intakes;
4. Easy maintenance, coupled installation;
5. Overflow protection;
6. Specially designed cutting system;
7. Alarm device;
8. Optional manual
9. Small size, easy to install
10. Convenient equipment maintenance and repair
11. The shell is made of polyethylene PE, which is one-time formed and has characteristics such as corrosion resistance, anti cracking, and environmental protection
12. It can be equipped with a cutting pump with independent cutting ability, which can cut long fiber impurities into a size range that can be discharged and pumped into the pipeline.
13. The product design is reasonable, the structure is compact, the floor space is small, and the product can be customized according to the actual situation on site, improving the utilization rate of space.
