PREVENTION OF WATER INGRESS IN HYDRAULIC SYSTEMS

Abstract

Industrial and mobile hydraulic systems are exposed to various environmental impacts. In order to achieve reliable operation and stable long-term use, we have to prevent ingress of different contaminants into hydraulic fluid and keep contamination levels on minimum. One of most common contaminants is water, which can significantly affect life-time of a hydraulic system. Thus, special attention should be paid to keep water content and humidity of hydraulic oil on lowest possible level, especially when using particular types of oil. The paper investigates different approaches on how to efficiently monitor water contamination and prevent water ingress into hydraulic system.
