This document contains procedure guidelines for the conversion from both water free and water based hydraulic fluids to QUINTOLUBRIC® 888.
One of the main considerations when choosing a hydraulic fluid, is it’s compatibility with seals. More specifically it’s compatibility with Nitrile Butadiene Rubber (NBR) seals. NBR is the most cost effective and commonly used seal type in hydraulic systems. This elastomer found in various hydraulic unit applications.
Most component failures are the direct result of contaminated hydraulic oil, and the expense of having to replace hydraulic components damaged by contamination is often eclipsed by the even higher cost of unscheduled downtime for the machine. Learn how hydraulic fluid cleanliness can be measured using several techniques and reporting methods.
The total acid number (TAN) is an analytical test to determine the deterioration of lubricants in service due to oxidation. As a fluid degrades with oxidation, the viscosity increases as well as the levels of corrosive acids, soot and varnish, along with the danger of component failure.
Monitoring through in-service oil analysis, an important element of predictive maintenance, can provide information about machine wear, as well as lubricant contamination and condition. By checking the appearance, viscosity, water content, acid number, cleanliness and solid metal and additive contents, the condition of the fluid can be measured.
Cutting and grinding coolants, diluted for use, are mostly water (95% water at a typical concentration). Water plays an important role in coolant performance. We need to understand how water affects metalworking coolants. This “Skill Builder” makes water crystal clear.
Quaker manufactures and sells fire resistant hydraulic fluids (FRHFs) under the brand name QUINTOLUBRIC®. Routine analysis of these fluids is sent to Quaker laboratories in Conshohocken, PA to the Q-TRAK lab. This lab assesses the FRHFs in a number of areas as detailed in this “Skill Builder.”
