Analysis and Treatment of the Degree of Guide Bearing of Large Hydrogenerator Set
A power plant unit in the operation of guide bearing degree,calendar year maintenance using conventional process are not effectively solve the problem of large degree,does not meet the company standard of high-quality goods units,guide bearing degree continues to increase to affect the safe and stable operation of the unit,for the situation in the maintenance period for industrial Internet degree data analysis,maintenance period combined with on-line monitoring data and unit maintenance plate car data comparison analysis,confirm the shaft collar round degree deviation and axis attitude orientation deviation is the main reason for the bearing degree is large.During the maintenance period,through the processing and repair of the circle of the upper shaft,the optimization of the unit axis swing orientation of the unit and the adjustment of the force of the thrust bearing,the problem of the guide bearing swing is handled.After the repair,the swing decreases significantly,reaching the index of the company's quality unit.According to the processing results can determine the unit in running pendulum in addition to the conventional imbalance force and axis quality,measuring circle,axis pendulum orientation,unit rotating axis running posture have different degrees of influence,unit maintenance optimization,improve such problems,to reduce the unit pendulum degree,improve the operation safety stability has good effect.
