Anhui Jina District Intelligent Wastewater Lift Pre-Made Pump StationStrengthen the construction of water conservancy infrastructure, further improve the systems for flood control, drainage, and irrigation in farmland, starting with the improvement of small and medium-sized river channels. Enhance the supporting facilities for industrial wastewater treatment, vigorously carry out wastewater treatment and river ecological restoration, and build a well-functioning water ecosystem with a good recycling function. To meet this requirement, it is essential to prevent the uncontrolled discharge of domestic and industrial wastewater into rivers and lakes. If we rely on the collection and lifting capabilities of an intelligent integrated precast pump station to enhance river circulation, how does the Zengqing River's integrated precast pump station achieve this?

1. When the pressure PI of the pump falls below the set pressure P2 required by the user, the automatic control of the variable-frequency pump's soft start operation is initiated until the actual pipeline pressure P equals P2. The microcomputer controls the variable-frequency pump to run at a constant speed. The higher the pressure PI of the pump, the slower the guide pump's speed, and conversely, the lower the pressure PI, the faster the guide pump's speed. When the pressure PI equals P2, the variable-frequency pump stops operating, fully utilizing the original pressure of the pump and ensuring a constant pressure as required by the user.

2. The variable frequency pump is connected to the flow stabilizer compensator. The microcomputer constantly monitors the pressure in the flow stabilizer compensator. The pre-engineered pump station controls the vacuum suppressor to stabilize the pressure of the compensator and the inlet, thereby preventing negative pressure. This ensures the normal supply of water in the pipeline network.

　　Anhui Jin'an District Intelligent Wastewater Lifting Pre-fabricated Pump StationThe equipment automatically shuts off, turns on, and resumes normal water supply after power outages. When the voltage falls below the set value, the prefabricated pump station's micro-mechanical automatic control initiates a variable frequency soft start operation for the pump. The water in the riser pipe serves as a compensator, and the equipment boosts water supply through a booster. When the pressure drops to a certain limit...
