Installation aligning method for shafting

Abstract

The invention discloses an installation aligning method for a shafting. Adjustment is easy and convenient, and meanwhile adjusting accuracy is high. The aligning method includes the steps that couplings are installed on two connecting shafts, and the relative radial deviation and end face deviation between the couplings on the two connecting shafts are measured in the vertical direction and the horizontal direction; the positions of the two connecting shafts are adjusted according to the radial deviation and end face deviation in the horizontal direction, and the axes of the connecting shafts are located in the same vertical plane; then the adjusting quantities of adjusting gaskets of supports at the positions from the first fulcrum to the nth fulcrum of the adjusting shaft are calculated according to the detected end face deviation and radial deviation in the vertical direction; and it is guaranteed that the position of the reference shaft is unchanged, the thicknesses of the adjusting gaskets of the corresponding supports at the positions from the first fulcrum to the nth fulcrum of the adjusting shaft are adjusted according to the acquired adjusting quantities of the adjusting gaskets, and then the two connecting shafts are coaxial. By the adoption of the aligning method, the steps are simple, operation is easy and convenient, aligning time is shortened, and adjusting accuracy is guaranteed.

Description

technical field [0001] The invention relates to an installation and adjustment method, in particular to a shaft installation and alignment method. Background technique [0002] It is well known that primary fans in thermal power plants are generally divided into two types: axial flow and centrifugal fans. Centrifugal fans are characterized by simple structure, high efficiency and low energy consumption, so they are widely used. However, in practical use, centrifugal fans are reliable in operation. There are many reasons for poor performance, such as design structure, manufacturing quality, etc. From the perspective of installation reasons, the shaft alignment quality directly affects the key factors in the later operation of the centrifugal fan, so improving the shaft alignment quality and speed will not affect the later stage. The operation quality has a good guarantee effect. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention i...

There are many reasons for poor performance, such as design structure, manufacturing quality, etc. From the perspective of installation reasons, the quality of shaft alignment directly affects the key factors in the later operation of centrifugal fans, so improving the quality and speed of shaft alignment is beneficial to the later stage.
