Embodiment 1

[0025] see Figure 1-4 As shown, a multi-purpose shroud for a submersible electric pump with built-in impeller includes a shroud main body 1, a connecting frame 2 and a support assembly 3, and the shroud main body 1 is detachably connected to the supporting assembly 3 through the connecting frame 2; The main body 1 of the wind deflector includes a conical pipe 4, the two sides of the conical pipe 4 are respectively fixedly connected with a small flange 6 and a large flange 7, and the upper end of the conical pipe 4 is fixedly installed with lifting lugs for lifting the main body 1 of the wind deflector. 5. The outer periphery of the lower end of the tapered pipe 4 is fixedly connected with a support frame 8, and the bottom of the support frame 8 is fixedly connected with a support base plate 9, and several groups of through holes for installation are provided on the support base plate 9; There are a lower support plate 17 and an upper support plate 20 for supporting the instal...

Embodiment 2

[0034] Such as Figure 5 As shown, the structure of the multi-purpose shroud of this embodiment is the same as that of Embodiment 1, and the water outlet of the submersible tubular pump with a built-in shroud impeller is used for diversion; The small flange 6 of the cover main body 1 is connected to the outlet flange of the submersible tubular flow pump 23, and the guide cover main body 1 and the support assembly 3 are fixedly connected through the connecting frame 2, and the support assembly 3 is placed under the submersible tubular flow pump 23 The submersible tubular pump 23 is supported.

Embodiment 3

[0036] Such as Figure 6 As shown, the structure of the multi-purpose shroud in this embodiment is the same as that of Embodiment 1. The shroud is used to change the flow of the outlet pipe of the submersible tubular pump with built-in impeller. Fix the main body of the shroud 1 through the foot bolts 24, connect the small flange 6 of the main body of the shroud 1 to the outlet pipe 25, disassemble the supporting assembly 3 from the connecting frame 2, and place the supporting assembly 3 in the diving pen. The submersible through-flow pump 23 is supported below the flow pump 23 .

Abstract

The invention discloses a multi-purpose shroud for a submersible electric pump with built-in impeller, which comprises a shroud main body, a connecting frame and a support assembly, and the shroud main body is detachably connected with the supporting assembly through the connecting frame; the shroud main body It includes a tapered pipe, the two sides of the tapered pipe are fixedly connected with a small flange and a large flange, the upper end of the tapered pipe is fixedly installed with lifting lugs for lifting the main body of the shroud, and the outer periphery of the lower end of the tapered pipe is fixedly connected with a support frame. The bottom of the support frame is fixedly connected with a support base plate, and several groups of through holes for installation are provided on the support base plate; a lower support plate and an upper support plate are provided on the support assembly, which are used to support the installation of the shroud. The diversion cover of the present invention can play different roles through different installation methods, which are respectively used for drainage at the water inlet of the submersible tubular pump with built-in impeller; Type submersible tubular pump outlet pipe variable flow.

Description

technical field [0001] The invention belongs to the technical field of shrouds, and in particular relates to a multipurpose shroud for submersible electric pumps with built-in impellers. Background technique [0002] Submersible pumps, as the main device for lifting water from deep wells, are generally placed underwater. The underwater situation is complicated. Often, underwater sediments block the pumps or the turbulent water collides with foreign objects to damage the pumps. Therefore, people install shrouds to protect the submersible pumps. The shroud is generally set outside the pump motor, which can protect the pump from underwater turbulent erosion, reduce foreign matter blockage, and prolong the maintenance cycle and service life of the submersible pump. [0003] At present, the submersible pump shrouds on the market are generally directly fixedly connected with the water pump motor box, and there is only one installation method, and the function of the shrouds is sin...
