Prediction of Hydraulic Pump Failures through Wear Debris Analysis.

Abstract

This report summarizes an investigation into the feasibility of monitoring hydraulic system wear debris characteristics in order to predict failures. The investigation utilized hydraulic pumps from an RA-5C aircraft hydraulic system and was monitored by spectrometric analysis and ferrography. Based on one relevant failure it was determined that ferrography can predict a failure of a pump prior to its occurence. Spectrometric results were not useful in the prediction. (Author)
