Investigation and adjustment of the pilot power unit equipped with a K-300-170-1R turbine produced by OAO Silovye Mashiny

Results obtained from investigations and adjustment works on a K-300-170-1R steam turbine carried out concurrently with a comprehensive set of works (adjustment of the support and suspension system of pipelines, analysis of thermal expansions of the cylinders and operating conditions of the bearings, optimization of the steam admission system, balancing works, and others) aimed at improving the turbine unit vibration performance are presented. The use of such integrated approach makes it possible to efficiently settle matters concerned with removing increased vibration of a turbine unit.
