Problems solved by technology

Due to the limited construction period and various limit conditions for on-site maintenance work (such as the position axis cannot be adjusted or the adjustable amount is small), once the general center data is measured, it is necessary to immediately carry out the center calculation and obtain the correct and optimal value as soon as possible. The calculation results conform to the actual situation on site, because the central calculation is a prerequisite for on-site adjustment. If the central calculation is wrong or delayed, it will not only lead to the failure of the on-site work implementation, but also lead to the delay of the on-site progress
In related technologies, professional technical engineers are usually required to perform calculations and adjustments on site. This method has low efficiency, high error rate and cannot meet the site limit conditions.

Abstract

The invention belongs to the technical field of nuclear power maintenance, and particularly relates to a center adjusting method and device for multi-shafting mechanical equipment. According to the embodiment of the invention, through collecting the size data of the multi-shafting mechanical equipment, depending on size data, opening error range and excircle error range, the multiple adjustment amount sets are determined, and the adjustment amount set meeting the preset condition is determined from the multiple adjustment amount sets and serves as the adjustment parameter for adjusting the multi-axis mechanical equipment, so that the optimal scheme capable of meeting the field error condition can be accurately determined in real time, and the equipment adjustment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of nuclear power maintenance, and in particular relates to a center adjustment method and device for multi-shaft mechanical equipment. Background technique [0002] The steam turbine generator set is a relatively common multi-shaft mechanical equipment. During the maintenance process, in order to ensure that the centerlines of each shaft are connected into a continuous and smooth curve, and to meet various maintenance restrictions on site, the load distribution of each bearing is in line with According to design requirements, adjusting the lift of the shaft system to the design requirements requires a special center adjustment, and center calculation is an important basis for center adjustment, and it is also an indispensable step. Due to the limited construction period and various limit conditions for on-site maintenance work (such as the position axis cannot be adjusted or the adjustable amount is small), ...
