Gas Turbine Generator Starting System.
Gas Turbine Generator Starting System.
(OP)
Hello everyone,
One of our gas turbines generator need the adjustement of an orifice manual valve (istalled at the bottom of solenoid
valve in the torque convertor oil circuit), however, this valve is never adjusted on the other turbines.
The opening/closing of the solenoid valves is controlled by the turbine logic control.
We adjust the valve in order to get the self sustained speed of the turbine main shaft, also avoiding
the starter moter get overloaded.
I wonder why the valve need an adjustement at each start up for this turbine.
Thank you

have you called your district service agent?

Please note that this valves were never adjusted in the other turbines.
Thank you.

1. Ensure the oil temperature is the same on all units, if the oil temperature is different in this particular unit the orifice will behave differently.
2. The orifice should have a set screw to keep it in position, make sure it is locked in position - mark the position with nail polish to confirm it moves from the position it was set to.
Then:
a. If the oil temperature is not the same (+/- 2°C) troubleshoot that problem: heaters on? difference in cooling water system?
b. If the orifice cannot be adjusted, change the device
c. If the orifice maintains the adjustment, exchange the orifice to another MS5001D and confirm that the problem follows the orifice.
