In this article the author discusses the last group of major components required for an auxiliary system. The coolers, filters and transfer valves are discussed. Referring to the generic definition of an auxiliary oil system, the function of the coolers, filters and transfer valves are to continuously provide cool, clean fluid to the critical equipment components. Examining this part of the definition in detail, continuously requires that components be dual filters and coolers. In addition, a means for on-line transfer of one bank of coolers and filters to the standby bank is required. This transfer must be accomplished without any significant pressure fluctuations, or flow disturbances in the auxiliary system. In order to assure pulsation free transfer, all components involved must be purged of air and must be full of auxiliary fluid. This requires that properly sized vent, bleed and fill lines be incorporated into the system. The function of providing cool oil is naturally that of the coolers. Coolers can be supplied in many different types and configurations. The requirements for clean oil is the function of the filters. Filters must continuously insure that all fluid supplied to the critical equipment is within the system specifications of cleanliness. 7 figs.
