Description

Circulating water pump calibrating device Technical Field The utility model relates to the technical field of water pump overhaul, in particular to a circulating water pump calibrating device. Background In an industrial circulating water system, a circulating water pump is used as one of core equipment, and the running stability of the circulating water pump directly influences the overall efficiency and the safety of the system. However, in the maintenance process of the circulating water pump, the calibration of the concentricity of the cylinder is particularly important. At present, the traditional concentricity calibration method generally depends on manual operation, for example, a mechanical measuring tool such as a dial indicator, a feeler gauge and a steel wire is adopted, and the relative positions of the cylinder body and the water pump shaft are adjusted through cooperation of multiple people. However, this method requires at least two persons to operate at both ends of the wire, one person being responsible for fixing the wire and the other person being responsible for adjusting the position and tension of the wire. The wire needs to be precisely aligned with the axis or reference point of the workpiece, which requires multiple persons to repeatedly adjust the position of the wire to ensure that it is parallel or coincident with the workpiece axis, which requires repeated corrections, which is time-consuming and labor-consuming, especially in a space-constrained working environment. Disclosure of utility model The utility model mainly aims to provide a circulating water pump calibration device, which aims to solve the problem that the concentricity calibration process of the existing circulating water pump usually needs to be matched by a plurality of people and is labor-consuming.
