The alignment tool for the main shaft center during the overhaul of the circulating water pump at power plants. The driving end of the pump is connected to the main shaft of the circulating water pump motor through an elastic coupling, enabling low-speed rotation of the main shaft. The rotating stand installed for maintenance does not obstruct the radial adjustment of the main shaft. It allows for continuous or intermittent rotation in either direction of the main shaft, with simple installation and convenient use.
