Description

Technical Field

[0001] The utility model relates to the technical field of submersible full-through-flow pumps, in particular to a pool wall self-coupling installation structure of a submersible full-through-flow pump. Background Art

[0002] A submersible tubular pump is a specially designed pump that combines the features of both submersible and tubular pumps. It is primarily used for liquid transport while operating underwater. Its design allows the pump body, motor, and other key components to be safely immersed in liquid for operation. It is typically used in drainage, irrigation, sewage treatment, and industrial water applications.

[0003] At present, there are two main ways to install the self-coupling of submersible full-flow pumps: 1. A through-wall pipe is pre-buried at the outlet of the submersible full-flow pump, and two symmetrical coupling seats are set on the through-wall pipe. A guide rail perpendicular to the bottom of the pool is arranged just above the coupling seat. Two symmetrical sliders are set on the motor housing of the submersible full-flow pump, and an annular O-type rubber sealing ring is set at the outlet end of the guide vane body. The disadvantages of this method are: when the sliders on both sides of the submersible full-flow pump enter the coupling seat along the guide rail, the O-type rubber sealing ring of the pump outlet flange is easily cut by the vertical flange of the through-wall pipe, and the sealing function is lost; because the guide vane body of the submersible full-flow pump is The body has a certain length, which will make the distance between the slider on the motor casing and the pool wall too large, and the coupling seat on the wall-penetrating pipe will extend a long distance. The weight of the pump will generate a large bending moment on the coupling seat, and the final force will be transmitted to the pool wall, increasing the stress on the pool wall structure; 2. Add concrete piers on both sides of the submersible full-flow pump, and symmetrically embed the coupling seat on the concrete piers through the positioning frame. The coupling seat is provided with an inclined guiding function. The slider on the submersible full-flow pump approaches the wall-penetrating pipe along the inclined surface of the coupling seat. This method can indeed effectively reduce the bending moment on the coupling seat, but it also increases the cost of civil engineering investment. Utility Model Content
