Consequences could include abrasive wear, increased leakage, component failure, control inaccuracies, blockage of control pistons, and short service life. The causes of solid contamination could be installation contamination, ambient contamination, refilling of operating fluid, internal wear processes and oil ageing. The causes and consequences of solid contamination, liquid contamination and gel-like contamination in oil are delineated. The index according to ISO 2902 is based on comparison to two mineral oils, with the higher the viscosity index of an oil the smaller the change in viscosity in relation to temperature. Oil classification in the app takes place according to API 1509 for base oils DIN for hydraulic oils and NSF International for food-grade oils.
The first section is on oils and their classification, viscosity and oil contamination. Once in click on ‘Fluid Care’ for the low down. The Tools app can be found on the top right hand side of HYDAC’s homepage, with the app available for free download via Google Play Store or Apple App Store.
To help its customers keep on top of their fluid care HYDAC has a fluid care Tools app handy to quickly resolve many a dilemma.
Paying attention to fluid is critically important as many have found out the hard way in machine failure and downtime.
