The water outlet of the centrifugal pump adopts a quick connector form, so that the centrifugal pump is simple and convenient to install and convenient to disassemble after being used.
Preferably, the impeller is integrally formed, the flow rate is large, and the efficiency is high.
The pump body adopts a precision casting process and is cast and molded by adopting a light aluminum alloy material. Of course, the material of the pump shell adopts various schemes according to different medium components.
The power adopts a hydraulic motor, and the pump has the biggest characteristics of small volume and light weight, and is widely applied to the fields of flood prevention and rescue, urban drainage, accumulated water removal in low-lying places and the like. Can convey various clean mediums containing certain particles such as rainwater, river water, seawater, various sewage and the like. The device is mainly used for occasions with large flow and low lift, and is particularly suitable for occasions such as outdoor temporary operation, river channel dredging, emergency rescue and disaster relief: urban flood control and drainage; cleaning and discharging the pit and the sewer; draining water in construction sites; water is taken from river channels and ditches for drought resistance; fire fighting water supply; chemical explosion-proof area drainage and the like. The device is particularly suitable for areas with strong maneuverability, imperfect electric power facilities or dangerous areas.
Compared with the prior art, the utility model has the beneficial effects that:
