Description
Technical field：
The present invention relates to a kind of hydraulic generator stator corrugated plating tightness to check process.
Background technology：
Conventional hydraulic generator stator corrugated plating tightness checks process, and the slot wedge sound is tapped with 0.5kg hand hammer, ripe
After knowing sound feature, remaining slot wedge taps the sound in contrast, judges corrugated plating tightness, such a inspection method by it is artificial because
Element limitation, local slot wedge is not urgent, can not detect comprehensively.In unit operation process, slot wedge easily loosens, and unit vibration is big.
The content of the invention：
The present invention relates to a kind of hydraulic generator stator corrugated plating tightness to check process, measures accurate, simple to operate
And a kind of hydraulic generator stator corrugated plating tightness of efficiency high checks process.Technical solution of the present invention is：A kind of water wheels
Generator unit stator corrugated plating tightness checks process, by stator bar (1), major trough wedge (2), secondary slot wedge (3), corrugated plating tightness
Model (4), wedge bar (5) composition stator corrugated plating tightness measurement apparatus are checked, is placed on stator bar (1) straightway more
Individual wedge bar (5), major trough wedge (2), secondary slot wedge (3) check that model (4) is together put into stator bar (1) with corrugated plating tightness
Interior, secondary slot wedge (3) is placed on corrugated plating tightness and checked between model (4) and major trough wedge (2), with making slot wedge instrument by secondary slot wedge (3)
It is urgent with major trough wedge (2), between measuring and controlling secondary slot wedge (3) exposed length L=100~125mm, measure wedge bar (5)
Actual (real) thickness, wedge bar (5) thickness meets installation requirement in this time slot, otherwise readjusts wedge bar (5) thickness, and will
Secondary slot wedge (3) and major trough wedge (2) are urgent, until the length of secondary slot wedge (3) exposed portion is measured between L=100~125mm,
It is with slot wedge instrument is made that secondary slot wedge and major trough wedge (2) is urgent in final using vernier caliper measurement wedge bar (5) actual (real) thickness
Position：After wedge bar thickness is determined, by stator bar (1), major trough wedge (2), secondary slot wedge (3), wedge bar (5), ripple
Plate (6) is positioned in core slots, with slot wedge instrument is made that secondary slot wedge (3) and major trough wedge (2) is urgent, and corrugated plating is measured with depthmeter
(6) decrement, corrugated plating (6) radial height is 1.25~1.40mm, meets slot wedge installation tightness requirement.
The present invention is so that generator unit corrugated plating tightness checks process as an example, according to original small with 0.5kg
Hammer taps the slot wedge sound, and after being familiar with sound feature, remaining slot wedge taps the sound in contrast, and this process judges corrugated plating
Tightness, the unurgent area of local slot wedge account for total slot wedge area 35%-40%.As examined by this hydraulic generator stator corrugated plating tightness
Process is looked into, improves slot wedge entirety tightness, the unurgent area of local slot wedge accounts for total slot wedge area 5%-10%.It is simple to operate
Convenient, efficiency high advantage, and then save installation period installation effectiveness and improve 50%.
The present invention fundamentally solves the problem of the local pine of hydraulic generator stator corrugated plating tightness.Can using the present invention
Measurement accuracy, simple to operate, efficiency high advantage are increased substantially, and then saves installation period.With corrugated plating tightness inspection
After model method determines wedge bar thickness, by the urgent slot wedge of this thickness, it is not necessary to (general to generate electricity in each core slots
Unit core slots 300-600 grooves)) need to redefine thickness, therefore installation effectiveness is improved, and according to said method slot wedge is urgent
Area accounts for total slot wedge area 90-95%, ensure that slot wedge tightness, unurgent so as to fundamentally solve slot wedge large area, can not
Detect comprehensive problem.
Brief description of the drawings：
Fig. 1 is that a kind of hydraulic generator stator corrugated plating tightness checks process schematic diagram.
Fig. 2 is hydraulic generator stator corrugated plating scheme of installation
Embodiment：
