Description
Technical field
The present invention relates to a kind of vertical hydropower generator Load brackets deflection metrology method, belong to fluid machinery and the energy
Technical field of engineering equipment.
Background technology
Today's society increasingly increases the demand of the energy, and water power is continuous as the clean energy resource being conveniently easy to get, exploitation dynamics
Increase, the capacity of the size of turbine-generator units constantly creates height.The increase of the weight of unit part dimension, proposes its reliability
New requirement.In vertical hydropower generator, Load brackets are used for placing generator amature, bear unit rotating part
Total weight, the axial hydraulic thrust of the hydraulic turbine and rack dead weight etc. are most important load bearing components.Load brackets need to have
Certain rigidity, to ensure the even running of bearing and whole rotatable parts.The wherein amount of deflection of Load brackets, is that its is most important
Performance indicator, therefore be badly in need of a kind of simple and reliable measuring method and check verification Load brackets amount of deflection at the scene, ensure unit peace
Full stable operation.
The content of the invention
The present invention is according to the above deficiency, provide a kind of vertical hydropower generator Load brackets deflection metrology method.
The technical scheme is that：
A kind of vertical hydropower generator Load brackets deflection metrology method, including：It is generator amature, generator shaft, bearing, negative
Lotus rack and concrete foundation, wherein,
Its outer ring of Load brackets is fixed on the inner ring platform of concrete foundation；
Generator amature is pressed on the outer shroud platform of concrete foundation through multiple uniformly distributed multiple brakes, and generator shaft lower part is inserted
Enter Load brackets through hole；
The whole circle thrust of the polylith of generator shaft and bearing is fixed；
The polylith thrust bearing shoe of bearing is fixed on the inner ring platform of Load brackets；
Whole circle thrust passes through oil film and thrust bearing shoe sliding contact；
Deflection metrology is carried out as follows：
Step 1：The top of ruler is fixed on more on Load brackets and close to generator shaft；
Step 2：More level meters are fixed in concrete foundation, every level meter can observe therein one ruler；
Step 3:Piston in all brakes is stretched out and jacks up generator amature, whole circle thrust does not connect with thrust bearing shoe
Touch, at this time, all on the brake, Load brackets do not accept the weight of generator amature to pressure to the weight of generator amature, pass through
The initial position of level meter recording rule；
Step 4：By the piston retraction in all brakes, brake is not contacted with generator amature, at this time, generator amature
All wt is pressed on thrust bearing shoe by whole circle thrust, final to be all pressed on Load brackets, Load brackets deformation, ruler
Move down, by the deformation position of level meter recording rule, the difference of deformation position and initial position is scratching for Load brackets
Spend changing value.
It should be noted that Load brackets have corresponding national standard, there is load adaptivity scope and around angle value requirement.
During generator normal power generation, the piston retraction in brake, brake is not contacted with generator amature, during maintenance,
During maintenance, piston, which stretches out, jacks up generator amature, and generator amature does not rotate.
Preferably, the ruler is micrometer, micrometer is inhaled on the Load brackets through magnet base.
The reading of micrometer can be as accurate as 0.10mm.
Preferably, the ruler has 6-12 handles, correspondingly, level meter has 6-12 only, ruler and level meter using generator shaft as
Center is evenly distributed with, and ruler is arranged on inner ring, and level meter is arranged on outer shroud, and each level meter is directed at nearest ruler.
Operation principle：The measured value of first time initial position be Load brackets dead weight produce amount of deflection, second of deforming position
It is the weight that Load brackets add hydrogenerator rotatable parts to put measured value, and each measurement result takes at least four level meters
Average value, finally post-processes double measurement Value Data, and the difference of secondary deflection metrology value is exactly that hydrogenerator rotates
Caused by component weight, therefore accurate estimation Load brackets deflection value can be used for.
The present invention has simple in structure, measurement convenience, the beneficial effect of high certainty of measurement.
