The shaft of the hydraulic generator bearing a new technology of maintenance

Hydraulic generator of electricity and water is directly related to the size and the water level drop, the higher the faster the water velocity generator speed, the higher the speed of concentricity the higher request. So on the motor shaft after repair to ensure concentricity is a key element, the motor shaft repair usually needs to stop the lathe turning disposal after repair, to ensure that the straightness, but in cannot complete processing, under the present situation of online repair their control is particularly important to ensure the concentric technology. Ever done or application tool rotating motor rotor spinning is generator bearing to reach the original work and size tolerance, or after repair concentricity and size tolerance within the allowable tolerance range necessary wrist. On generator bearing maintenance, it is necessary to repair the dimension of the concentricity, repair after tolerance and the precision of component matching request after repair, talents meet motor operation request. Sauvy carbon nano polymer material has the characteristics of metal and strength after curing, can satisfy the request car, milling, planing, grinding. Application in failing to finish machining, the tooling size and the plasticity of the data before solidification molding again a new location, with full equipment parts assembly condition and apply the request. Sauvy carbon nano polymer materials won't produce welding thermal stress, will not change the metal material performance. And sauvy tooling repair process is under cannot complete machining conditions lunch, fast and effective repair measures. Sauvy, industrial online repair process is different from the machining process, is under the condition of equipment not rotating restore trunnion sizes, initial processing is the motor shaft size as a benchmark to stop to repair, the repair form tolerance and size tolerance are able to control within the range. Sauvy the tooling according to the shaft on the dimensional precision positioning size tolerance finish machining, the machining accuracy is higher, the recovery of trunnion sizes more accurate. （ 1) Sauvy industrial carbon nano polymer materials to repair hydraulic generator bearing wear of steps on the basis of hydro-generator use environment and the speed of the motor, application of high motor bearing or adjacent size tolerance, the processing sauvy tooling is completed online repair to ensure the optimal plan, concentric site operation steps are as follows: 1. Applications outside micrometer level measurement axis neck size rear axle shoulder positioning size tolerance, processing the sauvy tooling; 2. After tooling, with inner dial indicator measurement size after treatment; 3. Test fixtures, preloaded bolt tooling no clearance, separation, rear axle shoulder hold, not loose; 4. Remove the tooling, check whether there is any damage on tooling wall brush besmear after SD7000 demoulding agent twice; 5. Bearing a roast with oxygen acetylene flame oil until the oil carbonization, control temperature to prevent the high temperature influence on the motor shaft to form; 6. On the basis of bearing SD7104 dimension and wear allowance calculation data dosage; 7. Harmonic SD7104 data to average, and then coated in appearance, bearing a repair coating materials; 8. Device overalls and tighten bolts, preloaded bolt; 9. Will repair parts heating with heat conduction way, promote information curing. 10. Remove the tooling, eliminate redundant data, measurement of trunnion sizes after repair; 11. Hot charging bearing and bearing locating ring; （ 2) Sauvy industrial carbon nanometer polymer materials technology repair hydro-generator bearing wear case pictures
