Seeking advice on sealing issues with centrifugal compressors
Thread Content
The first-stage double-seal of the compressor in this unit consists of a double-end dry gas seal and a labyrinth seal. During shutdown, when performing a nitrogen leak test, a leak was detected at the connection between the turbine and the shaft What is the cause of this situation? Does the secondary labyrinth seal allow leakage?
