Steam turbine part sleeve centering device

Abstract

The invention relates to a steam turbine part sleeve centering device which comprises a left mounting seat, a right mounting seat, a left pulley and a right pulley yoke, the left pulley yoke is mounted in the middle of the left mounting seat, a left rotating shaft is movably mounted on the left pulley yoke, and the left pulley is mounted on the left rotating shaft; a right pulley yoke is mounted in the middle of the right mounting seat, a right rotating shaft is movably mounted on the right pulley yoke, and a right pulley is mounted on the right rotating shaft; the left mounting seat and the right mounting seat are symmetrically mounted, a steel wire is wound on the left pulley and the right pulley, and hanging objects are mounted at the two ends of the steel wire; the steel wire is electrically connected with one end of the battery through a wire, the other end of the battery is connected with the earphone through a wire, and the earphone is connected with the inside micrometer. The working efficiency is improved, the construction period is shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to a steam turbine installation measuring device, in particular to a centering device for positioning the inner sleeve of a steam turbine cylinder before installation. Background technique [0002] In the installation of new units or in the transformation of steam turbines and the overhaul of steam turbines, there is positioning and installation of the inner cylinder sleeves, especially when the inner cylinder and other major sleeves are in place, it is necessary to locate the sleeves of the single cylinders separately to prevent the sleeves from being incorrect and affecting the impact. The safety of the host equipment and the efficiency of the flow, therefore, it is necessary to make a centering device for the steam turbine section. [0003] In the past, we used dummy shaft measurement or ordinary wire-drawn wire measurement for the alignment of large-scale transfer equipment such as steam turbines. The dummy shaft measurement n...

AI Technical Summary

Problems solved by technology

[0003] In the past, we usually used dummy shaft measurement or ordinary drawn steel wire measurement in the search of large-scale rotating equipment such as steam turbines. The dummy shaft measurement needs to be processed according to the axial size of the unit. The dummy shaft needs to be kept in good condition. It is troublesome and easy to transfer. Deformation occurs, while the ordinary steel wire measurement is generally a fixed wire measurement, which has high requirements for the measurement personnel and the accuracy of the measurement results is low

The conventional measurement process has problems such as delaying the construction period, wasting manpower, and increasing construction risks.
