Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fluid machinery, in particular to a high-lift circulation pump with anti-swaying stirring blades. Background Art
[0002] High-lift circulation pumps are primarily used to lift water or other fluids to a higher level and ensure that the fluid circulates within the system at a set flow rate. These pumps typically operate by creating a pressure differential between the inlet and outlet through the rotation of the impeller, thereby achieving fluid circulation. The design of the inlet impeller directly impacts the fluid's mixing efficiency. Properly designed impellers can improve fluid mixing uniformity, thereby enhancing pump efficiency. The type and structure of the impellers affect pump energy consumption. Optimizing impeller design can reduce energy consumption and improve pump efficiency. The inlet impellers alter the fluid's flow pattern, including velocity, direction, and vortexes. These changes can affect pump performance, such as head, flow rate, and efficiency. Improper impeller design can cause excessive impact or friction within the pump, accelerating wear and aging. When designing the inlet impellers, the specific pump application and operating conditions, such as fluid properties, flow rate, and head, must be carefully considered. The material selection for the impellers is also crucial; it must possess excellent corrosion and wear resistance. In actual application, the stirring blades also need to be inspected and maintained regularly to ensure their normal operation and extend the service life of the pump.
[0003] The existing high-lift circulation pump was found to have shortcomings during use. Its agitator blades lacked anti-sway support components, causing significant sway when water was introduced, which could easily cause motor vibration and output power fluctuations. Therefore, it was necessary to optimize and improve it. Utility Model Content
