Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3, including: a centrifugal pump body 1 and a pump body mounting plate 2 installed at the bottom of the centrifugal pump body 1 by bolts, the interface of the centrifugal pump body 1 is horizontally facing to one side, and a support bracket 7 is arranged below the interface, and a position adjustment groove 3 is opened on the surface of the pump body mounting plate 2 and is located below the support bracket 7. The groove shape of the position adjustment groove 3 is a convex shape, and an adjustment slider 4 is slidably installed in the groove of the position adjustment groove 3, and the adjustment slider 4 is adapted to the convex groove, and a part of the adjustment slider 4 passes through the position adjustment groove 3 and extends upward, and in the position adjustment groove A radially distributed adjusting screw 5 is also installed in the groove of the position adjusting groove 3, one end of the adjusting screw 5 is rotatably connected to the inner wall of the groove of the position adjusting groove 3, and the other end passes out from the groove of the position adjusting groove 3, and an operating handle block 6 is installed on the passing part, and a thread connected to the adjusting screw 5 is provided in the adjusting slider 4. When the adjusting screw 5 is rotated by operating the operating handle block 6, the adjusting slider 4 will move radially along the adjusting screw 5, and the top of the adjusting slider 4 is connected to the supporting bracket 7, so as to adjust the distance between the supporting bracket 7 and the interface of the centrifugal pump body 1.

[0025] An arc-shaped bracket groove 8 is provided on the top of the supporting bracket 7, and the arc-shaped concave surface of the bracket groove 8 is adapted to the arc-shaped portion of the lower part of the interface of the centrifugal pump body 1, and the bracket groove 8 can be moved below the interface, and the arc-shaped concave surface of the bracket groove 8 is to adapt to the pipe mouth of the butt joint pipe. During assembly, the pipe mouth of the butt joint pipe is placed on the top of the bracket groove 8, and the pipe mouth of the butt joint pipe is fitted with the interface of the centrifugal pump body 1, and then it can be reinforced by bolts, so that the butt joint pipe is no longer in a suspended state, which can reduce the difficulty of bolt installation, and in order to further keep the butt joint pipe stable on the bracket groove 8, two groups of block slots 9 are opened on the surface of the bracket groove 8, and limit blocks 10 are installed in the block slots 9, and the block slots 9 and the limit blocks 10 are distributed oppositely on both sides of the bracket groove 8. The connection between the limit stopper 10 and the block slot 9 is rotatably connected by an inserted shaft, so that the limit stopper 10 can rotate in the groove of the block slot 9. At the same time, a spring is installed between the limit stopper 10 and the block slot 9 to keep the limit stopper 10 protruding outside the block slot 9. When the butt pipe moves along the surface of the support block slot 8, the limit stopper 10 will be pressed into the groove of the block slot 9. When the butt pipe is attached to the pipe mouth and detached from the limit stopper 10, the limit stopper 10 is restored to its initial state by the spring. The slope of the limit stopper 10 in the initial state faces the operating handle block 6, and the vertical surface faces the centrifugal pump body 1. Therefore, the vertical structure of the limit stopper 10 is used to press the butt pipe against the pipe mouth surface of the centrifugal pump body 1, thereby improving the stability of the butt pipe during the bolt installation process.
