AI Technical Summary
When handling liquids containing solids, existing pumps are prone to impeller damage and costly unplanned maintenance due to blockage caused by large solid particles. Furthermore, existing technologies are not effective in preventing the accumulation of solids at the impeller seat inlet.
An improved impeller housing is designed with a stepped structure of guide pins and a leading edge designed to scrape off contaminants. This ensures that the impeller can move axially quickly when it encounters large solid materials, reducing accumulation. Solid materials can be more easily entered and discharged through the axial gap between the guide pins and the leading edge of the blades.
It effectively prevents solid matter from accumulating at the impeller seat inlet, reduces the risk of blockage, lowers the frequency and cost of unplanned maintenance, and improves the reliability and efficiency of the pump.
