Description

Technical Field

[0001] The present invention relates to the technical field of air gap measurement equipment, in particular to a read-and-measure air gap measurement tool. Background Art

[0002] In power systems, air gap measurement is an important step in ensuring safe operation of equipment. The air gap value will change after unit installation, commissioning, and maintenance. In particular, after the rotor is removed and reinstalled during maintenance, the air gap is very likely to change. The uniformity of the air gap will affect the stability of various performances of the running motor, thereby causing unit vibration and guide bearing wear. In the traditional measurement process, measurement is generally performed manually using tools. However, manual use of tools may cause incomplete or inaccurate tool locking, resulting in measurement deviations. Moreover, during the measurement process, manual readings are required after the measurement. The measurement and reading are performed separately, which will lead to inaccurate air gap measurements.

[0003] After searching, an air gap measuring device with publication number CN117053661A is found, which includes a fixed rod, a connecting mechanism, an adapter mechanism and an adjusting mechanism. The connecting mechanism is arranged on one side of the fixed rod, and the adapter mechanism is arranged at the bottom end of the fixed rod; by combining the fixed rod, the connecting mechanism with the adapter mechanism and the adjusting mechanism, the measurement gap data is determined by the dial indicator reading, and the fixed rod, the movable measuring rod, the measuring gasket and the dial indicator are used to measure and read the data, and the fixed plate, the fixing nut and the adjusting nut play the role of adjusting to the required position, and the adapter mechanism facilitates the sliding connection between the fixed rod and the movable measuring rod, and at the same time assists it in adjusting up and down, so as to achieve the required measurement effect.

[0004] The above invention adjusts the position of the measuring tool by fixing the nut and adjusting the nut.
