Solubility of Heavy Lubricants in Chlorinated Solvents

摘要

An investigation was made of the solvent action of chlorinated solvents in thick lubricants, as a means of determining optimum conditions for cleaning the liquid oxygen transfer line in the fueling system of WS315A. The results indicate that the solubility of lubricants in chlorinated solvents is directly proportional to temperature, surface area, and rate of flow. Trichloroethylene appears to be the most desirable solvent, and turbulent flow the most effective process. The action of solvents on greases appears to be specific for each type of grease and can be seriously affected by the presence of insoluble filler materials used in grease manufacture such as the metallic stearates. A solvent cleaning system with a flow velocity of 1.12 ft/sec (100 G.P.M.), at a temperature of 180F = 5, used for a period of 10 minutes in a single flushing process through the 6 inch transfer line should be sufficient to clean out any contaminant found in normal operations.
