According to the domestic 600 MW steam turbine generator a power generation company double flow ring seal oil tiles structure and the unit operation

analysis unit in opening and outage stage and operation period

because of the sealing oil differential pressure valve and balance valve work abnormal

foam tank liquid level higher cause into the generator seal oil

endangering the safe operation of the unit.In this paper

from the operational point of view may lead to the reasons for the generator into the oil generator to send hydrogen when the slow

to maintain the oil and hydrogen pressure stability and other appropriate preventive measures to prevent the generator into the oil.
