Abstract:

Contamination of hydraulic fluid filters was investigated. Performance equations for hydroclone operation were developed and experimentally verified. Hydroclones demonstrated 100 separation efficiencies for 10-micron particles. A semiautomatic hydroclone test stand was developed for obtaining separation efficiency of a filter either hydroclone or conventional element and for evaluation of cleaning methods. Contamination equipment included the Coulter particle counter, a chemical cleaning stand, an ultrasonic cleaning facility, and a filter evaluation stand. KC-135 and F-105 filter elements and hydraulic fluid samples were evaluated.
