A positioning plate 2 is installed on the outer wall of the pump housing 1 of the vertical long-shaft pump. A docking plate 3 is fixedly connected to the bottom of the positioning plate 2. A first bolt 4 is movably connected inside the positioning plate 2. A horizontal plate 5 is installed at the bottom of the positioning plate 2. A docking groove 6 is opened inside the horizontal plate 5. A threaded hole 7 is opened inside the horizontal plate 5. The docking plate 3 is snap-fitted with the horizontal plate 5 through the docking groove 6, and the docking plate 3 is symmetrically arranged with the central axis of the positioning plate 2. The first bolt 4 is threadedly connected to the horizontal plate 5 through the threaded hole 7, and the positioning plate 2 is of an open-hole design, which can facilitate the stable placement and use of the pump housing 1 of the vertical long-shaft pump.

[0025] Please refer to Figures 1-4 , a dynamic seal type vertical long-shaft pump. A slide groove 8 is opened inside the horizontal plate 5. A movable plate 9 is movably connected inside the slide groove 8. A limit hole 10 is opened inside the movable plate 9. A bracket 11 is fixedly connected to the outer wall of the movable plate 9. A second bolt 12 is movably connected inside the horizontal plate 5. The movable plate 9 and the horizontal plate 5 form a sliding structure through the slide groove 8, and the horizontal plate 5 is threadedly connected to the second bolt 12. The second bolt 12 is snap-fitted with the movable plate 9 through the limit hole 10, and the limit holes 10 are arranged at equal intervals on one side of the movable plate 9, which can facilitate the adjustment of the pump body placement rack according to the differences in the construction environment.

[0026] Please refer to Figures 1-4 , a dynamic seal type vertical long-shaft pump. A bearing plate 13 is fixedly connected to one side of the positioning plate 2.
