Research on Vibration Fault and Diagnosis Technology of Steam Turbine in Thermal Power Plant
As an important equipment for normal power generation in thermal power plants,turbine running for a long time may cause wear of key parts,and then cause trouble.The frequency of vibration faults is relatively high,and it is easy to affect the stability of the equipment.Therefore,troubleshooting should be carried out in time.Based on this,taking a thermal power plant as an example,the vibration fault diagnosis of steam turbine was carried out,and the fault states were analyzed from the perspectives of oil film vibration fault,static and static friction vibration,rotor fault vibration and steam flow excited vibration fault,and the technical measures for vibration fault diagnosis were explored,in order to improve the maintenance efficiency of steam turbine and ensure production safety.
