Dual pump mutual backup design: ensure uninterrupted sewage discharge

The Sewage Lifting Device is equipped with two high-performance water pumps and adopts a mutual backup design concept. This design can be called the "safety guard" for the stable operation of the equipment. In the actual operation process, sewage discharge is continuous. As the core power component, the water pump will inevitably fail after long-term operation. When one of the water pumps stops working due to mechanical wear, circuit failure or other reasons, the other water pump will start automatically and seamlessly replace the work of the faulty water pump to ensure that the sewage discharge is not affected. ​
Take a large underground parking lot as an example. Vehicle washing, rainy season seepage, etc. will generate a large amount of sewage. If a single pump of the sewage lifting device fails and there is no backup mechanism, the accumulated water will spread rapidly, affecting the passage of vehicles and even threatening vehicle safety. The dual pump mutual backup design avoids the failure of a single pump to cause sewage to be discharged, which in turn causes serious problems such as sewage backflow and flooding. It not only ensures the continuity of sewage discharge, but also greatly extends the overall service life of the equipment. Because the two pumps run alternately, the workload is shared, the continuous working time of each pump is reduced, the wear rate of components is reduced, the equipment can maintain a good working condition for a long time, the reliability of the equipment is greatly improved, and a solid guarantee is provided for sewage discharge. ​
High-efficiency large-flow treatment: meeting the needs of large-flow drainage​
The sewage lifting device adopts a large-displacement design and has the ability to efficiently treat a large amount of sewage, which makes it an ideal choice for places that require continuous large-flow drainage. In some large commercial complexes, hotels, hospitals and other crowded places, the amount of sewage generated is huge and the discharge is concentrated. If the treatment capacity of the sewage lifting device is insufficient, it will cause sewage accumulation, affecting the normal operation and environmental sanitation of the place. The sewage lifting device, with its large-displacement design, can quickly and effectively discharge a large amount of sewage to ensure the smooth operation of the drainage system. ​
For example, large hotels receive many guests every day, and a large amount of sewage will be generated in the cleaning of guest rooms, kitchen washing, and bathroom use, and the discharge time of these sewage is relatively concentrated. The sewage lifting device can treat these sewage in a short time to avoid odor and deterioration of sanitary conditions due to poor drainage. In addition, it is also very good at passing solid particles when treating sewage. Even if the sewage contains solid particles with larger particle sizes, the device can ensure that these particles pass smoothly without causing pipe blockage. This feature further enhances the practicality and applicability of the equipment, enabling it to work stably in various complex sewage discharge scenarios, without frequent pipeline dredging and maintenance, reducing operating costs and maintenance workload. ​
Intelligent control: realize automatic and convenient operation​
The fully automatic control cabinet equipped with the sewage lifting device is the core embodiment of its intelligence. The control cabinet supports automatic and manual dual-channel control modes, providing users with flexible and diverse operation options. In the automatic control mode, the device monitors the liquid level changes in real time through the float switch. When the sewage level rises to the set height, the float switch triggers a signal, and the control cabinet automatically starts the water pump to discharge the sewage; when the liquid level drops to a certain level, the float switch sends a signal again, and the water pump automatically stops running. The whole process does not require manual supervision, and fully realizes automatic operation, which greatly saves labor costs and improves work efficiency.​
Take the sewage discharge in the basement of a residential area as an example. Without the need for special personnel on duty, the equipment can automatically work according to the sewage level to ensure that the basement is always dry and clean. At the same time, the manual control mode provides convenience for the commissioning, maintenance and operation of the equipment under special circumstances. The operator can manually control the start and stop of the water pump according to actual needs to ensure that the equipment can operate safely and stably under various circumstances. This intelligent control method is not only easy to operate, but also greatly improves the safety of equipment use and reduces equipment failures and safety hazards caused by human operating errors. During the initial installation and commissioning of the equipment, the manual control mode can help technicians accurately adjust the equipment operating parameters to ensure the subsequent stable operation of the equipment. ​
Environmentally friendly materials: taking into account durability and installation convenience​
The box of the sewage lifting device is made of corrosion-resistant polyethylene material, which has multiple advantages. Polyethylene material has excellent corrosion resistance and can resist the erosion of various acid and alkali substances and chemical pollutants in sewage, ensuring that the box is not easily damaged or aged when in long-term contact with sewage, thereby extending the service life of the equipment. In some industrial areas, sewage may contain highly corrosive chemicals. The sewage lifting device using PE material box can work stably for a long time without frequent replacement of the box.​
The material has good air tightness, which can effectively prevent sewage leakage and odor emission, avoid pollution to the surrounding environment, and meet environmental protection requirements. In densely populated areas, good air tightness can ensure that surrounding residents are free from the trouble of sewage odor and maintain a good living environment. The box made of polyethylene material is compact and lightweight, which makes the equipment more convenient and flexible during installation. Whether in a small basement, bathroom, or other limited space, the installation work can be easily completed without complex installation equipment and a large amount of manpower investment, which reduces the difficulty and cost of installation, and also provides convenience for the later maintenance and replacement of the equipment. In the renovation project of old buildings, the narrow space brings challenges to the installation of equipment, and the compact and lightweight PE box sewage lifting device can be installed smoothly to meet the sewage discharge needs. ​
Multiple water inlet design: flexible adaptation to complex water inlet requirements ​
The sewage lifting device has reserved multiple water inlets. This design fully takes into account the complex and diverse water inlet needs of different places. In actual applications, the layout of drainage pipes in buildings varies, and the source of sewage is also relatively scattered. The design of multiple water inlets allows users to flexibly arrange the water inlet pipes according to the actual pipeline direction and sewage collection point, and smoothly introduce sewage from different locations into the lifting device. ​
In large office buildings, sewage from toilets, tea rooms, cleaning rooms and other areas on each floor needs to be discharged centrally. By reasonably connecting multiple water inlets, these scattered sewage sources can be efficiently integrated. Whether it is sewage from different areas such as toilets, kitchens, laundry rooms, or sewage from multiple floors, it can be discharged centrally by reasonably connecting water inlets. This flexible design method improves the versatility and adaptability of the equipment, enabling it to meet the sewage discharge needs in various complex building environments. There is no need to carry out large-scale transformation of the equipment to adapt to specific water inlet conditions, saving time and cost. In the renovation project of the commercial complex, even if the original drainage system is adjusted, the sewage discharge path can be quickly replanned through the multiple water inlets of the sewage lifting device to ensure the normal operation of the drainage system. ​
Low noise design: creating a quiet and comfortable environment​
The noise generated by the sewage lifting device during operation is extremely low and will not interfere with the surrounding environment. In some places with high noise requirements, such as residential areas, schools, hospitals, etc., if the sewage lifting device is too noisy during operation, it will seriously affect the quality of life of residents, the learning environment of students, and the rest and recovery of patients. ​
In residential areas, people are extremely sensitive to noise when they are resting, and low-noise sewage lifting devices will not break the tranquility of the night. The sewage lifting device controls the operating noise to an extremely low level by optimizing the internal structure design and adopting technical means such as silent components. Even if the equipment continues to run, it will not produce obvious noise interference, creating a quiet and comfortable atmosphere for the surrounding environment. This design feature not only improves the user experience of the equipment, but also makes it widely used in more noise-sensitive places, reflecting its advantages in humanized design. In special areas such as school libraries and hospital wards, low-noise sewage lifting devices can work silently without disturbing people's normal activities and rest.
