Abstract

Abstract: The damper preventing air blast of coupling of 600 MW domestic units, which was newly installed or newly overhauled, was often fall off in trial operation, and this has an adverse effect on safety operation of unit. Some typical accidents were enumerated and analyzed, and the problems needing attention in installation of the damper preventing air blast in coupling were pointed out to avoid similar accident.

Key words: coupling, damper preventing air blast, machining precision, installation method
