Detailed application of vertical suspended long axis semi submersible sump pump in urban landscape water system circulation drainage

The vertical suspended long axis semi submersible sump pump, with its core characteristics of low noise, long service life, and large flow continuous and stable transportation, is the core fluid transportation equipment for ecological circulation and water quality maintenance of urban landscape water bodies in the urban landscape water system circulation drainage scene. It fully adapts to the special working conditions of low interference and long-term continuous operation of landscape water systems. The specific application details are as follows:
Core application scenarios of urban landscape water system circulation
·Global ecological cycle of landscape water bodies: As the core driving force of water system cycle, the water bodies of landscape lakes and rivers are extracted from low-level areas and transported to upstream high-level areas, constructing a closed water cycle system for the entire area, breaking the stagnant water environment of stagnant water bodies, and increasing the dissolved oxygen content of water bodies.
·Water system replenishment and dynamic regulation of water level: During the dry season, clean water bodies are extracted from municipal backup water sources or groundwater sources to supplement the water level of the landscape water system. During the rainy season, excess rainwater in the water system is quickly discharged to maintain the landscape water level stable at the design elevation throughout the year, ensuring the viewing effect of the landscape water system.
·Supporting water treatment process for water supply: providing stable pressure water sources for water purification facilities such as filtration, ultraviolet disinfection, and artificial wetlands supporting landscape water systems, promoting continuous treatment of water bodies through purification units, rapidly degrading nutrient rich substances in water bodies, and eliminating the hidden danger of blue-green algae outbreaks.
·Emergency water quality replacement scheduling: When the water quality of the landscape water system deteriorates or suddenly pollutes, all contaminated water bodies can be quickly replaced and discharged, and new clean water sources can be introduced simultaneously to quickly restore the water quality of the landscape water system in a short period of time.
✅  Core advantages of scene specific adaptation
·Low noise operation without interference: With a vertical direct drive structure and a shock-absorbing base, the operating noise can be controlled within 55 decibels, far below the environmental noise standards of urban areas, and will not cause noise interference to surrounding residents and landscape tourists.
·Long term continuous operation life: The core components are made of super duplex steel or 304 stainless steel material, which is resistant to trace chloride ions and algae corrosion in landscape water bodies. The designed service life can reach more than 15 years and can meet the requirements of low load continuous cycle operation for 365 days a year.
·Installation concealed without damaging the landscape: The pump unit is directly installed in the underwater pump room or concealed collection well on the shore of the landscape water system, with only a small number of maintenance facilities remaining on the ground, completely without damaging the overall visual style of the landscape water system, and suitable for the landscape design requirements of urban parks and commercial complexes.
·High operational energy efficiency: Designed with an efficient hydraulic model, the highest operational efficiency can reach 82%. The energy consumption for long-term high flow circulation transportation is more than 20% lower than that of traditional submersible pumps, significantly reducing the electricity cost for the year-round circulation operation of landscape water systems.
Key points for scene specific selection
·The selected flow rate is calculated based on the total volume of the landscape water system and the required water circulation cycle. Conventional landscape water systems require a full water circulation to be completed every 7-15 days to determine the total flow rate of the circulation pump group.
·The head is calculated based on the terrain elevation difference of the water system circulation and the resistance loss along the pipeline, without the need to reserve excessive head margin, to avoid unnecessary energy waste.
·304/316L stainless steel material is preferred for overcurrent components, which can withstand the corrosion of algae and a small amount of salt in landscape water bodies, avoiding the problem of corrosion and water pollution caused by long-term operation.
·Equipped with a frequency conversion intelligent control system, the pump set's operating flow rate is dynamically adjusted based on real-time dissolved oxygen and water quality indicators, further reducing long-term energy consumption and achieving unmanned automated operation.
At present, a large number of landscape water circulation projects in urban parks and commercial complexes in China have adopted vertical suspended long axis semi submersible sump pumps as the core circulating power equipment in batches. They operate stably and reliably for a long time, and can effectively maintain the ecological health and landscape effect of landscape water systems.
