Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, specifically to a rotor disassembly device for a submersible jet motor. Background Technology

[0002] In the process of biological wastewater treatment, submersible jet mixers are often installed in the biological tank to promote the flow of wastewater within the tank. The jet mixers facilitate the flow and circulation of wastewater within the tank, thereby ensuring the effectiveness of wastewater treatment.

[0003] In practical engineering, due to continuous production and operation, submersible jet generators also work intermittently. After long-term operation, equipment failures are inevitable. In actual production, faulty equipment needs to be repaired rather than directly replaced. Therefore, when repairing a faulty submersible jet generator, it is necessary to disassemble its motor before checking and repairing the fault. Since the bearing housing of the submersible jet generator motor is an interference fit with the housing, the original disassembly method in the factory was to lay the motor flat and fix it, and then manually pull out the bearing housing (using the clamping mechanism of this utility model to clamp and fix the bearing housing, and manually exerting force outward at both ends). At this time, the rotor can be taken out. However, the process is time-consuming and laborious. At the same time, due to the weight of the rotor itself, it is easy to suffer mechanical damage during the pulling process, which shortens the service life of the equipment.

[0004] Therefore, through further use and optimization in the production process, this utility model proposes a rotor disassembly device for a submersible propeller motor. The motor is placed vertically in the placement seat, and then the bearing seat is clamped and fixed by the clamping mechanism. The clamping mechanism is lifted by the lifting mechanism, which lifts the bearing seat and loosens the fit between the bearing seat and the rotor shaft. The operation is more stable and reliable during the process, which can effectively avoid secondary mechanical damage to the motor and help ensure the service life of the equipment.
