Researches concerning the hydraulic oil degradation process in gear pumps

Abstract

The paper investigates the degradation and contamination level of the hydraulic oil used on an endurance stand for testing two different types of gear pumps. Experimental results have been obtained using a Brookfield CAP2000+ viscometer, for determining the oil rheological parameters. Also, the paper presents the Parker CM Laser Particle Analyser used for measuring the size and density of the oil wear particles. The results focused on lubricant analysis represent practical ways to apply predictive and proactive maintenance for hydraulic gear pumps, but also for other hydrostatic equipment
