Causes of turbine vibration
Thread Content
The vibration readings at the four measurement points before and after the turbine show a similar pattern; recently, the values have often increased suddenly before dropping again after ten minutes. What could be the reason for this?
Are there any historical records of fluctuations in steam temperature, pressure, or flow rate? Or there may be abnormal conditions such as fluctuations in the gas flow rate of the compressor or liquid entrainment. These are the only things that come to mind
Operating condition factors, mechanical factors, and interference factors – it’s difficult to draw a conclusion in just a few sentences
Reasons for sudden vibration in turbines: 1. System-related issues: Fluctuations in steam inlet pressure and temperature； Fluctuations in turbine exhaust pressure ； Fluctuations in compressor operating conditions ； Fault in the engine control system, transmitting false signals ； To control issues such as the rupture of the inner tank in the oil accumulator. 2. Internal reasons: Abnormalities in certain components of the system itself. It is necessary to pay close attention and observe carefully; different units have different causes, so different countermeasures must be devised.
