Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a turning tool for a vertical water pump coupling. Background Technology

[0002] Before starting the water pump, manually rotate the pump shaft to check for smooth rotation and any abnormal noises. This prevents the pump shaft from jamming during startup, which could cause excessive starting load on the motor, exceeding the rated current and burning out the motor. The couplings of vertical water pumps, deep well pumps, and submersible pumps are located inside the motor housing, where the working space is limited. Manually rotating the pump with both hands can easily lead to bumps and injuries, and insufficient force may prevent proper rotation. Using pry bars or pipe wrenches is inconvenient, unsafe, time-consuming, and laborious. Existing manual rotation tools are inadequate for the required conditions. Utility Model Content
