Description

Technical Field

[0001] The utility model relates to the technical field of submersible pump impellers, in particular to an impeller disassembly and assembly device for a submersible pump. Background Art

[0002] Submersible pumps are important equipment for extracting water from deep wells. When in use, the entire unit dives into the water to extract groundwater to the surface. The impeller is an important component of the submersible pump. When installing the submersible pump, the impeller needs to be placed in the submersible pump, and a mounting rod is installed in the submersible pump. The mounting rod needs to be passed through the impeller, and the impeller fixing nut is threaded onto the mounting rod, and the impeller is fixed by the impeller fixing nut. Due to the special shape of the impeller and the narrow installation position of the impeller fixing nut, there is a lack of corresponding tools to disassemble it, resulting in the staff only being able to manually complete the disassembly of the impeller fixing nut, which makes the disassembly of the impeller fixing nut very troublesome.

[0023] When the cam is in operation, the cam 12 is unlocked and the cam 24 is unlocked, so that the cam 12 can be unlocked and the cam 24 is unlocked, and the cam 12 can be unlocked, so that the cam 12 can be unlocked and the cam 12 can be unlocked, and the cam 12 can be unlocked, so that the cam 12 can be unlocked.

[0024] In an optional embodiment, the mating component includes a mounting plate 4 and multiple limiting rods 5, the mounting plate 4 is coaxially arranged with the second mounting rod 2, and the second mounting rod 2 and the mounting plate 4 are detachably connected via the connecting component, and the mounting plate 4 is provided with multiple limiting rods 5 for matching with the impeller fixing nut at one end away from the second mounting rod 2, and the multiple limiting rods 5 are matched with the impeller fixing nut, that is, the limiting rods 5 are inserted into the limiting holes on the impeller fixing nut, so that by rotating the first mounting rod 1, the first mounting rod 1 rotates to drive the connecting rod 3 and the second mounting rod 2 to rotate, thereby driving the mounting plate 4 to rotate, and the mounting plate 4 rotates to drive the limiting rod 5 to rotate, thereby driving the impeller limiting nut matched with it to rotate, and the impeller limiting nut rotates and moves on the mounting threaded rod of the water pump to complete the disassembly and assembly of the impeller.

[0025] In an optional embodiment, the connecting assembly includes a mounting plate 9, a first through hole is coaxially provided on the second mounting rod 2, two slide grooves are spaced apart on the inner wall of the first through hole, a slider 8 is provided at one end of the mounting plate 4 facing the second mounting rod 2, the slider 8 extends into the slide groove and is slidably connected to the second mounting rod 2, the mounting plate 9 is arranged in the first through hole and connected to the second mounting rod 2, and a limiting unit is provided at the bottom end of the mounting plate 9 for limiting the slider 8. Since two sliders 8 are provided on the mounting plate 4 and the slider 8 slides in the slide groove, the slider 8 can be preliminarily limited by the inner wall of the slide groove, and the slider 8 can be further installed by the limiting unit, thereby completing the installation of the mounting plate 4 and the second mounting rod 2.

[0026] In an optional embodiment, the limiting unit includes a transmission block 10, a spring 11, an extrusion block 12 and a limit block 14.
