Lubrication of MARINE TURBINES

An authoritative paper on the lubrication of turbines was included in our January issue. This was devoted, principally, to the evolution and use of modern lubricating oils. Details were also given of hydrogen cooled alternators for land machines. The paper below is concerned only with marine turbines and is a practical paper for assistance to all steam turbine designers, manufacturers and, of course, operators. It covers the various types of marine turbine lubricating systems, design features that minimise risk of oil contamination and the precautions to be taken by manufacturers before patting their machines into commission. The paper is a condensation of one given at a recent meeting of the American Society for Testing Materials at San Francisco by FREDERICK S. JONES, of the Socony‐ Vacuum Oil Company Inc. Reference is made in this paper to “double inhibited oils”, and this is taken to mean oils that contain both oxidation and rust inhibiting additives.
