Integrated prefabricated pump station with fiberglass cylinder for corrosion resistance and efficient improvement of sewage and rainwater

Description :

  Integrated prefabricated pump station is a modern sewage treatment and transportation equipment that integrates submersible pumps, grilles, control systems, pipelines, and valves. It mainly solves the problem of sewage and rainwater in low-lying areas that cannot be discharged by gravity. It lifts liquids to municipal pipelines or treatment plants through built-in high-efficiency submersible sewage pumps. Typical operating conditions include urban overpass drainage, residential area sewage collection, rural decentralized sewage treatment, and industrial park wastewater lifting. This device is installed underground and does not occupy ground space, effectively avoiding the spread of odors and noise disturbance to residents. It is particularly suitable for areas with tight land use or high landscape requirements. The core advantage of integrated prefabricated pump stations lies in their highly integrated and automated operation capabilities, which can automatically start and stop according to changes in liquid level, achieve unmanned operation, and significantly reduce the labor cost of later operation and maintenance. They are important infrastructure components in modern sponge city construction and water environment governance.

  The cylinder of the integrated prefabricated pump station is usually made of high-strength wound glass reinforced plastic (GRP) or stainless steel, with strong corrosion resistance, aging resistance and leakage resistance, and the design service life can reach more than 30 years. The wall thickness of the cylinder is optimized through mechanical calculations based on diameter and depth to ensure it can withstand soil pressure and ground loads. Internally equipped with high-performance submersible axial flow pumps or mixed flow pumps, the flow range covers 10m ³/h to 5000m ³/h, and the head can be customized according to actual needs, up to a maximum of 30 meters or more. The control system comes standard with a PLC intelligent control cabinet, which supports remote monitoring, fault alarm, and data upload, and meets the protection level of IP55 or above. The bottom adopts a self-cleaning base design, utilizing fluid dynamics principles to form eddies, prevent sediment deposition, and reduce dredging frequency. All pipelines and valves are treated with 304 stainless steel or anti-corrosion coating, and the connections are made with flanges or hot melt connections to ensure sealing. The overall structure is compact, with a high degree of prefabrication in the factory and a short on-site installation cycle.

  When selecting an integrated prefabricated pump station, key parameters such as inlet pipe diameter, daily processing water volume, peak flow rate, and required head should be carefully considered. For rainwater discharge scenarios, attention should be paid to the instantaneous drainage capacity under short-term heavy rainfall, and a high flow low head pump type should be selected; For sewage treatment, it is necessary to consider the impurity content in the medium and equip it with a crushing grid to prevent blockage. If the groundwater level at the installation site is high, anti floating design should be carried out on the cylinder body, and additional weight or anchoring measures should be added. Compared with traditional concrete pump stations, the construction period of integrated prefabricated pump stations is shortened by more than 70%, and there is no risk of concrete cracking. However, the initial investment is slightly higher, making it suitable for projects with strict requirements for construction period and environmental protection. Not suitable for extreme working conditions containing a large amount of flammable and explosive gases or highly corrosive industrial waste liquids. In such cases, customized pump stations made of special materials need to be selected. When selecting, it is also necessary to confirm the power supply conditions and communication interfaces to ensure the stable operation of the remote control system.

  The installation of the integrated prefabricated pump station should be carried out after the foundation pit acceptance is qualified. During the lifting process, collision with the cylinder should be avoided to ensure that the verticality deviation is within the allowable range. The backfill soil should be compacted layer by layer, using medium coarse sand or fine soil without stones to prevent sharp objects from puncturing the anti-corrosion layer. Daily maintenance mainly includes regular checks on the operating current, voltage, and vibration of the water pump, cleaning of debris intercepted by the grille, and preventing blockages from affecting the water inlet efficiency. It is recommended to check the connection and insulation performance of electrical components in the control cabinet every six months, and calibrate the liquid level sensor annually to ensure accurate control logic. Common faults such as overheating or abnormal noise in the pump body are often caused by foreign objects wrapped around the impeller or worn bearings. It is necessary to stop the machine in a timely manner for cleaning or replacement of components. When the pump station is not in use for a long time, the accumulated water in the cylinder should be drained, the power should be disconnected, and rust prevention maintenance should be carried out on the equipment to extend the overall service life of the integrated prefabricated pump station and ensure the safe and stable operation of the drainage system.
