Decontamination of Hydraulic Fluids and Dynamic Hose Study

摘要

The report includes a description of the installation of the prototype hydroclone on standard hydraulic test stands as a means of upgrading the decontamination capabilities in USAF ground support equipment. The acquisition of hydraulic fluid samples from the field installations and the laboratory tests of these samples are discussed along with a technical comment on the results of the various analyses. A comparison of filtration performance of the hydroclone and the final filter presently being used on the hydraulic test stands is presented. Studies on field test units are presented which were conducted to determine the maintainability, compatibility endurance limits, reliability, and service life of the hydroclone and its critical components. A recommended test procedure is presented for the verification of hydroclone performance and the establishment of qualification requirements for quantity production. General design criteria curves for optimum hydroclones are given which can be used to design a hydroclone, using MIL-F-5606 hydraulic fluid, to separate specific sizes and densities of various contaminants found in USAF ground support equipment. A unique method for the dynamic testing of high pressure hose assemblies and the cleaning of new hose assemblies is presented along with the contaminant generating characteristics of high pressure hoses constructed of various materials.
