Combination semi submersible suspended vertical centrifugal pump device

Combination semi submersible suspended vertical centrifugal pump device, including a box body, the box body is a rectangular box body, and the bottom of the rectangular box body has no cover plate; There are four semi submersible suspended vertical sump pumps installed at the top of the box, symmetrically arranged along the transverse centerline and longitudinal centerline of the box. The pump outlet pipe of each semi submersible suspended vertical sump pump is installed at the top of the box, and each pump outlet pipe is located between the semi submersible suspended vertical sump pump and the short side plate of the box; There are lifting rings installed between each pump outlet pipe and the long side plate of the casing; There are push rods symmetrically arranged along the transverse centerline of the box on the left and right side plates of the upper part of the box; The pump outlet pipe and the corresponding semi submersible suspended vertical sump pump are on the same centerline. This technical method has a reasonable structure, reduces the length of the water intake pipe, and uses four pumps and four channels to simultaneously intake water, accelerating the speed of water intake from the fire truck water tank. It provides a guarantee for protecting people's lives and property safety, and has good economic and social benefits for promotion and application.
