Embodiment 1
[0018] Such as figure 1 and figure 2 The shown guide bracket includes a base plate 1 and a stainless steel sleeve 2 fixed on the base plate 1 . The base plate 1 is provided with a plurality of connection holes, on which screw components 3 are mounted, and the base plate 1 is connected to the base through the screw components 3 . The screw fastening part 3 may be a bolt.
[0019] A collar 4 is arranged inside the pipe of the stainless steel sleeve 2 . The collar 4 is a polytetrafluoroethylene collar 4, the thickness of the collar 4 is 20 mm, and the outer wall surface of the collar 4 is attached to the pipe side wall of the stainless steel casing 2. This technical solution provides a guide bracket, the collar 4 of the guide bracket is a polytetrafluoroethylene collar, and the small friction coefficient between the polytetrafluoroethylene collar and the stainless steel sleeve 2 can effectively reduce the friction between the guide bracket and the stainless steel sleeve 2.

Embodiment 2
[0021] Such as image 3 and Figure 4 The guide structure of a pump body of a vertical high-pressure centrifugal pump shown includes a vertical high-pressure centrifugal pump 5 . The vertical high-pressure centrifugal pump 5 includes a casing 51 and a pump body disposed inside the casing 51 . The outlet pipe 53 of the pump body is a bent pipe, and the corner end of the bent pipe is an arc surface, and a branch pipe 54 is vertically connected to the lower end of the arc surface.
[0022] The branch pipe is supported by a guide bracket, and the guide bracket includes a base plate 1 and a stainless steel sleeve 2 fixed on the base plate 1 . The base plate 1 is provided with a plurality of connection holes, on which screw components 3 are mounted, and the base plate 1 is connected to the base through the screw components 3 . A collar 4 is arranged inside the pipe of the stainless steel sleeve 2 . The collar 4 is a polytetrafluoroethylene collar 4, the thickness of the collar 4...
