Turbine fluctuation solution
Thread Content
Sometimes, the flow rate of medium-pressure steam used in our turbines increases suddenly by about 1 ton, while the rotational speed remains unchanged; as a result, the temperature of the supporting shaft rises and vibration levels increase. How can we determine the location of the fault? ? ? Thank you to all the masters for leaving messages
It’s usually very stable, but sometimes it experiences fluctuations. I’m worried about cascading shutdowns, and I can’t find the cause to address it! Thank you
It is speculated that both the fluctuations in steam pressure and the constant rotation speed are results of automatic speed regulation; there are likely some issues with the bearing shells, which cause changes in the rotational resistance. It is recommended to analyze the vibration patterns and conduct an inspection at an appropriate time.
What type of turbine is it? Is it a extraction-type turbine?
