Cylinder Oil 600 W What Is For, What Will It Do 1920

GARGOYLE CYLINDER OIL 600 W Object of Cylinder Lubrication The object of internal lubrication in a steam engine is, first, to form a lubricating film between the rubbing sur- faces and thus replace the metallic friction with fluid fric- tion, as far as possible; second, to form an oil sealing film in order to prevent leakage of steam past the val ves, pistons and giand packings. The internal moving parts, comprising valves, valve rods, piston and piston rod, are exposed to high temperature con- ditions and, with the exception of the valve rod and piston rod, none of the internal parts are exposed to view, so that the’condition of lubrication cannot easily be inspected. The internal lubrication of the steam cylinders and valves is, therefore, of much greater importance and much more diffi- cult than the lubrication of the external moving parts, com- prising the crosshead, crank pin, main bearings, eccen- trics etc. Only the correct grade of high quality cylinder oil, applied in the right way, to the right place, and in the right quan- tity, will enable the steam engine to operate at its highest efficiency and with a minimum cost for renewals and repairs. Correct lubrication is therefore chiefly dependent on the methods of lubrication employed and the selection of the correct oil to meet the operating conditions of each indi- vidual case. . Methods of Lubrication Points of In order to lubricate the internal parts of Application steam cylinders and valves, cylinder oil is introduced into one or more of the following points: 8
