Embodiment Construction

[0087] The present invention will be further described below in conjunction with the drawings and embodiments:

[0088] See Figure 1 to Figure 22 , An intelligent dimple measuring device, which determines whether the rotor 2 is coaxial with the dimple 1 by measuring the gap 4 between the steam turbine rotor 2 and the dimple 1 (that is, the center coincides).

[0089] In order to adapt to the measurement of full cylinder and half cylinder, the dimple measuring device is divided into a full cylinder measuring device 3 and a half cylinder measuring device 5. The half-cylinder measuring device 5 is used for figure 1 The middle dimple 1 has only a semicircle or the dimple is not a complete circle.

[0090] The dimple measuring device includes a chip and a carriage. The chips can be divided into a full-cylinder chip A and a half-cylinder chip C; the carriage can be divided into a full-cylinder carriage B and a half-cylinder carriage D;

[0091] See figure 2 For full-cylinder measurement, ...

Abstract

The invention discloses an intellectualized bore testing device which comprises brackets and chips. The chips are fixed on the brackets. The testing device is divided into a full-cylinder testing device and a half-cylinder testing device. The full-cylinder testing device is suitable for the full-cylinder testing; the half-cylinder testing device is suitable for the half-cylinder testing . The full-cylinder testing device comprises full-cylinder chips and full-cylinder brackets; the half-cylinder testing device comprises half-cylinder chips and half-cylinder brackets. The intellectualized bore testing device utilizes specific special testing transducers. Central distances of a steam turbine rotor and a bore is tested accurately; the power of work is reduced greatly; work efficiency is improved; precision measurement and alignment accuracy of devices are improved.

Description

Technical field [0001] The invention relates to a dimple measuring device for steam turbines, in particular to an intelligent dimple measuring device capable of recording measurement displacement and corresponding angle in real time. Background technique [0002] Measuring and adjusting the center of the steam turbine and the dimple is the last process in the installation or overhaul of the steam turbine generator: measuring and adjusting the center distance between the high-pressure, medium-pressure, and low-pressure steam turbine rotor and the dimple diaphragm. Maintaining the best center between dimples is the most important key to the safe operation and energy saving of steam turbine equipment. [0003] To improve the center quality of the adjustment rotor and the dimple, first of all, the measurement accuracy between the turbine rotor and the diaphragm should be improved. Since the structural gap between the steam turbine rotor and the dimple diaphragm is very small, there is...
