Centrifugal compressor
Thread Content
I’d like to ask the experts: why does a centrifugal compressor need to activate its dry gas seal first before starting its lubrication system?
The isolation gas on the outermost layer of the dry gas seal prevents lubricating oil from reaching the seal; otherwise, it could damage the seal. Therefore, the isolation gas must be activated first, before the lubricating oil system is turned on. This is specified in the manual for using the dry gas seal
