Description
Technical field
The present invention relates to vertical outstanding type hydrogenerator maintenance technique fields, more particularly to a kind of vertical outstanding type hydraulic generator
Machine thrust collar quick decomposition method.
Background technique
Large and medium-sized vertical outstanding type hydrogenerator structure unit, the top of main shaft all installed thrust heads, with thrust bearing shoe valve, runner plate
Equal components form thrust bearing together, and key and snap ring power transmission are used between thrust collar and main shaft, is leaned between thrust collar inner hole and main shaft
It is interference fitted fixed center of rotation.Thrust collar plays the weight for bearing unit rotating part and axial water pushes away when unit is run
Power is that stress is heavy, complicated, the very high part of required precision, it requires thrust collar should have enough intensity, rigidity and
Any undesirable loosening is not allow for after certain impact flexibility, with the cooperation of big axis to happen.
Turbine-generator units are intended to carry out large repairs in the operation 6-8 year, and when overhaul needs to remove thrust collar, but due to year
Corrosion is serious long, a great problem when this work of dismounting thrust collar is at major overhaul, simultaneously because brought by maintenance
Wear-out failure can be such that fit clearance is gradually increased.What current each factory generally used is all using cold-drawn thrust collar technology.Cold-drawn pushes away
The workflow of power head is as follows: 1, removing the connection bolt of snap ring and thrust collar；2, generator amature is jacked up, snap ring is removed；
3, it removes thrust collar and connect bolt with runner plate；4, the thrust collar tool special for dismounting and lifting handle of producer's offer have been provided, and
Adjustment is horizontal.Cold-drawn thrust collar work can be carried out after the completion of these preparations, concrete operations are as follows: two groups of personnel use simultaneously
Two three meters of long steel pipe sockets are on box spanner, urged clockwise steel pipe uniform rotation, successively tighten on specific purpose tool later
Eight nuts of screw rod.Symmetrical tightening, technical staff measure every now and then in turn on such circle circle ground, formulate correcting scheme,
Thrust collar is gradually backed out generator apical axis under the lifting force effect of fixed equipment bit by bit.This disassembly thrust collar
Method needs 10 people: pushing away extension bar and needs 6 people, adjustment box spanner position needs 2 people, and the monitoring of thrust collar level needs 1 people, always refers to
1 people is waved, lasting more than ten hour could complete, and this method is cumbersome and time consuming.
The method of this cold-drawn thrust collar continues to use traditional artificial mechanism method, by the spiral shell for successively tightening symmetry direction
Cap is completed, and whole process is the process of matching surface phase mutual friction, due in the pulling force size of symmetry direction and action time
On disunity, the case where often resulting in unilateral drawing, be engaged stress concentration region surface, shearing and worn.When matching
When closing close, the contact stress acted on matching surface is very big, occurs burr in opposing compression sliding process, and bite occurs.
So the method for this cold-drawn thrust collar is quite serious to the abrasion of fit clearance, after dismounting, can obviously be seen in matching surface
To scratch, bite trace.Since faying face is damaged, thrust collar will loosen, and jiggering data are just influenced whether when obvious
Accuracy and unit centre adjustment, be unfavorable for the safe and stable operation of unit.
Therefore, it is necessary to provide a kind of new above-mentioned skill of vertical outstanding type hydrogenerator thrust collar quick decomposition method solution
Art problem.
