Description

Technical Field

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

[0002] When repairing a submersible pump, disassembly is difficult due to the impeller's structural design. The impeller is made of brittle material, a flat, circular, hollow structure. The innermost shaft hole is keyed to the motor shaft, and there are no locating holes on the inner water inlet ring. Furthermore, to improve the pump's energy efficiency, the impeller's surface is smooth and curved, lacking holes for bolt installation. The impeller is installed inside the water reservoir. To ensure vacuum, the gap between the outlet trough and the water reservoir is small, making it difficult to insert and secure with standard tools, and there is no way to remove the impeller. Hitting the water outlet directly with a hammer can break the impeller and outlet.

[0003] Therefore, it is urgent to design a device that can easily disassemble the impeller without causing damage to the impeller. Utility Model Content

[0020] The submersible pump impeller disassembly device provided by the utility model uses the diversion water channel 101 of the water outlet of the impeller 1 as the fulcrum of the right-angle hook 2, and uses the flange 3 as the intermediary for transmitting power between the right-angle hook 2 and the movable hammer 4. The impeller 1 is pulled by the movable hammer 4, and the impeller 1 can be gradually pulled out by relying on the inertia of the movable hammer 4 to complete the disassembly of the impeller 1. The device is simple and easy to manufacture, and improves the maintenance efficiency. At the same time, it can also ensure that the water nozzle and the impeller 1 are protected from damage, thereby reducing material consumption.
