Description

Technical Field

[0001] This utility model belongs to the field of axial flow pump technology, specifically an underwater axial flow pump with a filter cover to prevent foreign objects from getting stuck. Background Technology

[0002] An underwater axial flow pump is a fluid machine that integrates a motor and impeller directly underwater, utilizing the axial thrust of the rotating impeller to achieve horizontal liquid transport. Its core structure consists of streamlined guide vanes and a helical impeller. During operation, the liquid flows along the pump shaft, featuring high flow rate, low head, and high efficiency, making it particularly suitable for large-volume, low-head applications. Its applications are wide-ranging, covering water conservancy projects such as river water intake, farmland irrigation, and urban flood control and drainage; in the environmental field, it is used for water circulation and sludge transport in sewage treatment plants; in municipal engineering, it assists in the scheduling of urban landscape water systems and the drainage of rainwater storage tanks; in aquaculture, its uniform water supply characteristics maintain dissolved oxygen levels in fishponds; furthermore, in the shipbuilding industry, it can be used as a ballast water pump or fire pump, and its underwater concealed installation and corrosion-resistant design make it a core piece of equipment for hydraulic transport in multiple industries. The filter cover of existing underwater axial flow pumps is fixed and is easily clogged by impurities in the water during use, which in turn blocks the water flow and affects the pumping efficiency. At the same time, it requires frequent shutdowns for manual cleaning, which increases maintenance costs. Utility Model Content
