What interlock will be triggered by a low temperature of the seal air for the turbine shaft seal?
We don’t have interlocking. From Hangzhou Motor.
To date, no interlocks related to shaft seal steam have been observed; a low shaft seal pressure can lead to air leakage on the vacuum side, resulting in a decrease in vacuum level. Generally, a low vacuum level triggers an interlock that shuts down the system
There is no interlock at the steam seal; I’ve seen cases where the pressure was low – initially low-pressure steam was used, but it was later changed to normal-pressure steam
I have only seen the interlock that opens the shaft seal air supply valve when the shaft seal pressure is low; I really have never seen an interlock related to a low shaft seal steam temperature. But there’s an interlock symbol on the flowchart; I really don’t understand it
