AI Technical Summary
Existing technologies make it difficult to conveniently test ultra-long submersible pump motors, leading to overheating and fatigue damage to the motor, pump body, and bearings under abnormal operating conditions, which affects the service life and reliability of the equipment.
A submersible pump motor dynamometer device was designed, including a base, a test motor, a torque sensor, a shaft box, a coupling, and a mounting assembly. The submersible pump motor is fixed by rolling elements and clamps, and the height is adjusted by a lifting assembly to achieve stable connection and testing.
It improves the convenience of testing, ensures the stability and safety of the submersible pump motor during the testing process, and enables the verification of its performance under different speeds and loads.
