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

GARGOYLE CYLINDER OIL 600 W feed varies with the engine-room temperature and every time the lubricator is filled with fresh oil. Modern conditions of high steam pressure and high steam temperature make it desirable, and in some cases necessary, to use mechanically operated lubricators wliich can be relied upon to automatically feed the high-grade oil uni- formly and regularly. Selection of Cylinder Oil Efficient Efficient lubrication produces a polished, Lubrication glossy surface on the valve rods, valves and valve faces, piston rods, piston rings and cylinder walls. The valves and pistons operate with- out noise, the eccentric rods operating the valves work smoothly, and when opened for inspection the internal frictional surfaces show a complete lubricating film. When the steam cylinders are opened for inspection, the surfaces should present a rather duli appearance, coated with a film of oil, the presence of which can be determined by wiping a piece of paper over the cylinder walls at various parts of the stroke. On wiping off the oil film, the surface underneath should appear bright and glossy. With good lubrication it is easier to keep the packing giands tight, as the complete film of lubricating oil helps to make a perfect seal, and the packing will last longer. Poor Lubrication Poor lubrication manifests itself in different ways with different types of engines. Slide valves and piston valves groan, and the 12
