Vibration Analysis On 125MW Unit Of Shijiazhuang Thermoelectric Power Plant

The No.16 steam turbine of Shijiazhuang Thermal Power Station was made in Hebei, China, whose type is C100-8.83/0.883. After being used, when it running at 3000r/min speed, the vertical amplitude of No.5 bearing reach 140μm, the horizontal amplitude of No.7 and No.8 bearing reach 140μm, this influenced the safety seriously of the unit operation. To settle the fault, the author use"the vibrating fault diagnosis system of turbo-generator unit based on Kohonen network"do a some Vibration tests .With the diagnosis software of the paper and the testing data, the author finds out the cause of the No.3 unit's fault. The amplitude of No.3 and No.5, and No.6 reached good standard. This also shows that the software has important supervising meaning for site fault diagnose.
