This post was last edited by Kuju Kikuko on 2010-10-5 00:03. Why is it necessary to wait until the vacuum level reaches zero when shutting down a turbine?
Reply #22010-08-25
Reason: Since the inside of the machine is a vacuum, once the shaft seal stops functioning, the cold air outside will be drawn in immediately, causing rapid cooling inside. This leads to deformation of the internal components, which is a problem waiting to happen
