Greetings,
1.We have 7 FA turbine, the lift oil pressure is 3500 psig, and the lockable flow control valve is adjusted so that the shaft is lifted by 5 mils approximately.I wonder what would happen to the pressure of lift oil if we increase the lifting distance and put is for example 7 mils instead of 5. Because in one hand we are opening the valve more which means less resistance but on the other hand the oil will be subjected to more load while lifting the shaft more distance.
The next question is not for a specific system, but to help general troubleshooting. What effect does the orifice have on the system pressure and flow rate if the only change was done on the system is the orifice? (upstream and downstream)
