Description

Technical Field

[0001] The utility model relates to the technical field of mixed flow pumps, in particular to a strong suction type mixed flow pump. Background Art

[0002] A mixed flow pump is a device that can suck water or liquid, accelerate its circulation through rotating blades, and finally eject it through an outlet. Its characteristics are between centrifugal pumps and axial flow pumps, and it can achieve both large flow and high head. Mixed flow pumps are usually used in industrial fields, such as farmland irrigation, water supply systems, etc., and can efficiently transport liquids.

[0003] When the existing strong-suction mixed-flow pump is in use, it is necessary to connect the drive shaft at the output end of the high-power motor with the middle of the mixed-flow blades in the strong-suction mixed-flow pump. However, the high-power motor is heavy. When the high-power motor and the mixed-flow pump are installed, the staff need to carry the high-power motor, which increases the labor intensity and causes the working efficiency of the strong-suction mixed-flow pump to be low when in use. For this reason, we propose a strong-suction mixed-flow pump. Utility Model Content
