Process for converting a fluid system of a machine from an oil based fluid system to a water based fluid system

摘要

A process for converting a fluid system of a machine from an oil based fluid system to a water based fluid system. A solvent and perfluoroethylene resin are added to the fluid system in sufficient amounts to remove extraneous matter from and coat the surfaces within the fluid system with the perfluoroethylene resin. The oil based fluid, solvent and perfluoroethylene resin are circulated throughout the fluid system for a time sufficient to remove extraneous matter and coat the surfaces. The fluid system is evacuated of the oil based fluid, solvent and residual perfluoroethylene resin, and a water based fluid is added to the fluid system.
