Can the turbine continue to operate after the seal oil pump of the heavy fraction hydraulic turbine in the residue hydrogenation unit shuts down?
Thread Content
The seal flushing scheme selected for the hydraulic turbine is 32+53C. If the seal oil pump with model 32 stops operating, in order to prevent residue oil from entering the isolation fluid tank of 53C, is it necessary to stop the turbine immediately, or can it continue to operate? Experts with practical experience, please share your approaches.

Current seals are generally used to prevent leaks from occurring; the system can operate for a short time, but it is best to stop it immediately for repairs.
How long do you usually shut down the oil pump, so that the turbine can keep running?
It’s uncertain; sometimes the mechanics say there’s no problem, but we assume the seal is completely damaged in such cases. It’s best to carry out repairs immediately, as hydraulic turbines operate under high temperature and pressure conditions, and leaks in these areas are very difficult to deal with.
