Embodiment Construction

[0034] Such as Figure 1~3 As shown in Fig. 1, a method for adjusting the axis of a hydro-generator unit using the projection analysis method is to insert multiple shims between the thrust head 1 and the inclined opening of the mirror plate 2, and determine the positions and heights of the shims respectively , place the determined shims along the X-axis of the thrust head 1 to the other side of the thrust head 1 for storage, and place the thrust head 1 parallel to the mirror plate 2 to keep the main shaft 5 vertical.

[0035] The method of confirming the position of the gasket is as follows:

[0036] The position of the first spacer 3 is calculated by measuring the swing value of the main shaft 5. After calculating the maximum swing position of the main shaft 5, the placement direction of the first spacer 3 is also determined after the maximum swing position is determined, that is, the Y axis and the The intersection point of the outer circle of the thrust head 1;

Abstract

The invention provides a method for adjusting the axis of a water-turbine generator set through a projection analysis method. The method comprises the steps that multiple gaskets are plugged between a thrust block and an inclined opening of a thrust runner collar, the positions and the heights of the gaskets are determined, and the multiple determined gaskets are placed on the other side of the thrust block along an X-axis mirror image of the thrust block. The thrust block is plugged and padded to be parallel to the thrust runner collar so that a main shaft can be kept vertical. The technical innovation achievement can be applied to maintenance of many water-turbine generator sets, in particular to axis adjustment and clearance distribution of guide shoes of the generator sets, the working efficiency is improved, the turning times are reduced, the required time is shortened, and the overhaul period is shortened.

Description

technical field [0001] The invention relates to the field of adjusting the axis of a hydraulic turbine generator set, in particular to a method for adjusting the axis of a hydraulic turbine generator set using a projection analysis method. Background technique [0002] The thrust bearing bears axial force along the major axis of the hydro-generator, bearing the full weight of the vertical hydro-generator set, and the weight of the hydro-generator is transmitted to the thrust tile through the thrust head (mirror plate). In order to ensure the thrust head (mirror plate) and the verticality of the hydro-generator shaft, a plastic insulating gasket is installed between the thrust head and the mirror plate, the radial direction of the upper guide bearing, the lower guide bearing, and the water guide bearing is the diameter direction of the major shaft of the hydro-generator set Bearing the force, bearing the radial swing force during the rotation of the hydro-generator set, the g...
