[0012] Referring to the figures, the present invention specifically adopts the following implementation mode: including a rectangular steel plate 1, a rectangular steel plate 2, a U-shaped cardboard 3 and a jack top plate 4, the rectangular steel plate 1 and the rectangular steel plate 2 are steel plates of the same size, the rectangular steel plate 1 and the rectangular steel plate 2 are connected at one end and form a triangular prism with the ground, the rectangular steel plate 1 and the rectangular steel plate 2 are respectively provided with a rectangular hole 1 and a rectangular hole 2 6 at the center of the plate body, the inner wall of one side of the rectangular hole 1 and the rectangular hole 2 6 is connected by the U-shaped cardboard 3, and the inner wall of the other side of the rectangular hole 1 and the rectangular hole 2 6 is connected by the jack top plate 4. The rectangular steel plate 1 and the rectangular steel plate 2 are steel plates of the same size, and the length, width and thickness are: 1600mm*850mm*25mm. The rectangular hole 1 5 and the rectangular hole 2 6 are holes of the same size, with the length, width and thickness of 1300mm*650mm*25mm. The shaft of the water pump rotor impeller passes through the bottom of the U-shaped card plate 3 and the bottom of the jack top plate 4. A jack is placed between the jack top plate 4 and the shaft of the water pump rotor impeller. The jack is a 32-ton screw jack. The jack top plate 4 is a square plate with a length, width and thickness of 350mm*350mm*25mm. The U-shaped card plate 3 is a square plate with a U-shaped opening, and its length, width and thickness are 350mm*350mm*25mm.
[0013] The tool for disassembling a water pump rotor impeller of the present invention comprises five parts in total, and the sizes of the following equipment parts can be adjusted according to actual needs.
[0014] The first and second components are: 2 pieces of rectangular steel plates 1 and 2, 1600mm*850mm, with a rectangular hole of 25mm thickness and 1300mm*650mm size (can be adjusted as needed, or an adjustable size frame can be made); The third component is: a square jack top plate 4 with a thickness of 25 mm and a size of 350 mm*350 mm; The fourth component is: a U-shaped pallet 3 with a thickness of 25 mm and a size of 350 mm*350 mm; The fifth component is: a 32-ton screw jack.
[0015] Pass the shaft of the water pump rotor impeller through the U-shaped clamping plate 3 and clamp it firmly, clamp the screw jack between the jack top plate 4 and the water pump rotor impeller shaft, and fix the screw jack. Use the screw jack to apply pressure to the rotor shaft to remove the water pump rotor, and complete the disassembly of the water pump rotor impeller; the reaction force on the screw jack is offset by the jack top plate 4.
[0016] When the water pump rotor impeller disassembly tool is used, one side shaft of the water pump rotor impeller is inserted into the U-shaped notch of the U-shaped clamping plate 3 and kept stable, and then the screw jack can be clamped between the jack top plate 4 and the other shaft tail of the impeller (if the distance is too far to make it impossible to clamp the screw jack, a steel column of appropriate height can be added to the jack top plate 4), and finally the impeller can be disassembled by applying pressure to the shaft through the screw jack.
[0017] In summary, the water pump rotor impeller disassembly tool has a simple structure, is easy to operate, is suitable for disassembling impellers of different sizes and specifications, has high maintenance efficiency, sustainable use, high safety, and good flexibility.
