A method for optimizing centering adjustment of a coupling in installation of a combustion engine

Abstract

The present application belongs to the technical field of gas turbine installation and shafting measurement, and relates to a method for adjusting and optimizing the centering of a coupling in gas turbine installation. The present application takes each foot of a generator as the object of centering adjustment, determines the measurement position, measurement direction and end face circumferential positioning mark of the coupling, obtains the radial deviation and axial opening before and after the transfer, determines the adjustment direction before and after the transfer according to the measurement results and the position relationship of the feet, tightens each foot to be tightened one by one, compares the centering changes before and after the tightening, releases and delays when the centering state before the tightening cannot be maintained, locks when the centering state before the tightening is maintained, and re-measures and outputs the centering result of the coupling after the locking of each foot. The present application solves the problems that the inconsistent determination of the radial deviation and the axial opening is caused by the state change of the measuring device, and the centering drift after the tightening of the feet is difficult to trace, and achieves the effects of distinguishing the measurement change and the real drift, reducing the repeated adjustment of the feet, and forming the basis for the re-measurement after the tightening.
