Turbine governor control valve to operate sluggishly, and how would you troubleshoot this issue?
If you find yourself facing a slow turbine governor control valve, do not worry there are several things you can do to solve the problem. Begin with a simple check, which involves observing the pipe for any signs of wear and tear or signs of leakage.
After that, check that all the moving parts are well lubricated – you would be at how many times this can fix the issue. Make sure your hydraulic system is okay, check the fluid level and pressure, and see whether the actuator is working properly.
Make sure to check the control system logs for issues that may require your attention. If you are still unable to identify the cause, you may have to explore further and look at the insides of the valve and the mechanical parts that connect to it.
Also check the valve position feedback system.
Do not forget to focus on the servo valve and calibration settings as well. If none of the above work, do some load testing to see how the valve behaves under different loads.
Safety first – always do things by the book and do not be afraid to seek help from someone who knows best.
As you know, valves are complex mechanical devices, but with a little time and systematic approach to problem solving, you will have that valve working like a charm in no time.
