Description

Technical Field

[0001] The utility model relates to the technical field of integrated axial flow pumping stations, in particular to an integrated axial flow pumping station with a self-cleaning mechanism. Background Technique

[0002] Integrated axial flow pumping stations are mainly used for water resource management, drainage and irrigation. The pumping station quickly conveys a large amount of water bodies to the target area through an axial flow pump to ensure unobstructed water flow. However, since the pumping station is usually installed in areas with dense water flow, its base is easily affected by sediments and sludge. Impurities and sediment in the water will deposit at the bottom of the pumping station, especially the base, when the water flow slows down. These sediments not only affect the normal operation of the pumping station, but may also cause wear and corrosion of the equipment. Therefore, keeping the bottom of the pumping station clean is crucial for ensuring the long-term stable operation of the pumping station.

[0003] Most of the integrated axial flow pumping stations on the market currently lack an automatic cleaning function, which makes it difficult to remove sewage and silt at the bottom of the pumping station. Traditional cleaning methods usually require shutting down the machine for manual cleaning, which is not only time-consuming and laborious, but may also interrupt the normal operation of the pumping station, affecting water resource management and drainage efficiency. In addition, manual cleaning is difficult to be thorough, and the remaining sediments will still cause wear and corrosion to the equipment, shortening the service life of the pumping station. Due to untimely cleaning, sludge and impurities accumulate at the bottom of the pumping station, which may cause blockage and operation failure of the pumping station, increasing the maintenance cost and repair frequency.

[0004] Therefore, it is of great significance to develop an integrated axial flow pumping station with a self-cleaning mechanism. Content of the Utility Model
