Problems solved by technology

There are mainly the following problems in using the dummy shaft for centering: In order to avoid the quality of the dummy shaft being too long (steam turbines generally need to be more than 6 meters long) and the deformation caused by its own weight, the dummy shaft is generally made thicker. guarantee its rigidity
Therefore, the dummy shaft is generally cumbersome and wastes materials; because the coaxiality is guaranteed by radial equidistant when centering, the circumferential machining accuracy of the dummy shaft is high, the surface finish is high, and processing is difficult; in order to match the dummy shaft For use, both ends must have high-precision support, and each end needs a specially processed dummy bearing; it is time-consuming and laborious to adjust the position of the dummy shaft

The device in the invention comprises a steel wire drawing frame, wherein the steel wire drawing frame is arranged on a support through a steel wire frame supporting plate and comprises a bottom plate; the bottom plate is provided with an adjusting device; a steel wire fixing frame is connected with the adjusting device; and the steel wire fixing frame is provided with a steel wire pulling block.

Description

[0001] technical field [0002] The invention relates to a steel wire centering device for assembling a steam turbine. Background technique [0003] As a high-temperature, high-pressure, and high-precision equipment, the steam turbine requires high positional accuracy of the impeller during its assembly process, so an auxiliary centering method is required. At present, the main centering method existing in China is the centering of the false shaft, that is, the false shaft is firstly aligned through the cylinder so that it is located in the center of the steam turbine cylinder. Then use it to center the newly installed impeller. There are mainly the following problems in using the dummy shaft to find the center: in order to avoid the quality of the dummy shaft being too long (the steam turbine generally needs to be more than 6 meters in length), and the quality of the alignment caused by the deformation caused by its own weight, the dummy shaft is generally made thicker. g...
