Description

Technical Field

[0001] The utility model relates to the technical field of axial flow pumps, in particular to an axial flow pump capable of freely switching the flow direction. Background Art

[0002] An axial-flow pump is a pump that uses the rotation of its impeller to drive the blades to exert force on the fluid, thereby transporting the fluid along its axis. Currently, conventional axial-flow pumps exist in two main structural forms: a curved-tube axial-flow pump and an integrated axial-flow pump. Traditional axial-flow pumps typically have a fixed flow direction, which limits their flexibility in many practical applications. For example, in situations where the flow direction needs to be changed according to different operating conditions, traditional axial-flow pumps are unable to meet these requirements. Therefore, we propose an axial-flow pump with freely switchable flow direction to address this problem. Utility Model Content
