| Abstract: | A gas turbine in a certain gas company didn't work normally because of its strong vibration.Although this turbine had been balanced repeatedly at low speed, the vibration amplitude and unbalance weight of the machine changed irregularly. The causes and characteristics of the vibration are discussed. According to the change of the critical speed and the characteristics of vibration, it is found that the vibration is caused by weakness of the tight force on the central rod of the rotor and the oil whirl of the back bearing of the compressor. After clearing these faults and balancing the rotor of the compressor at high speed, the turbine worksnormally again. |
