Hi.
When we were overhauling a centrifugal compressor which is connected to a motor through a speed increaser (gearbox), we noticed when we opened the gearbox cover that there as some melted metal on the shaft just underneath gearbox labyrnith seal of the high speed shaft (5800 rpm). Why would the seal melt ?!
