ESR T2 Investigation
From Cryowiki
Jump to navigationJump to search
ESR turbines could have modified bearing gas systems. This needs to be clarified for both turbines.
T2 will sometimes stop (following a trip) after a significant amount of time (< 10 minutes), or not stop at all.
When pressure is applied to T2 inlet valve, the turbine will slowly spin. High level of confidence that the inlet valve leaks by.
- investigate bearing gas process at ESR
- Verify LVDT on turbine inlet valve
- Warm T2. Schedule. Dependent on transfer line.
- Check seating force of T2 inlet valve (require trip?) (verify proper operation)
- Can T2 be isolated to support troubleshooting without damaging turbine or stopping entire CBX?
- Develop plan to isolate CBX in the event T2 must be stopped, and/or CBX must be tripped.
- Verify that we have a spare.
- What is required to check seating force (operationally)?
- Create an alarm that will alert us when turbine inlet valves are closed and turbine speed is > 0.
- drink a beer
- Get the transfer line from CHL operational
- follow-up meeting ~1/20/2017.
- Contact Pete to begin information/data collection, vendors, contacts.
