Quaker Houghton wanted to show that QUINTOLUBRIC® 814-02 could not only meet these requirements but also reduce costs through increased productivity and reduced downtime and maintenance requirements.
Quaker Houghton also provided an engineering solution for Bridger’s mixing system, which was producing low mix ratios. Quaker Houghton was able to identify and fix the problem. Even at low mix concentrations, QUINTOLUBRIC® 814-01 did not separate, scum or show signs of bacterial growth.
Ronald Knecht (hydraulic fluids expert) and Jon Brown (mining expert) from Quaker Houghton, discuss the pros and cons of alternative mineral oil-based hydraulic fluids that reduce the risk of fire hazards in mining operations.
First, Quaker Houghton helped the manufacturer to understand the advantages of changing from water glycol (HFC) fluids to polyol ester (HFD-U) fluids. These advantages include
Quaker Houghton’s QUINTOLUBRIC® polyol ester HFD-U fluids are fire-resistant hydraulic fluids that do not contain water. HFD fluids are usually based on synthetic base stocks or esters that combine reasonable to good fire-resistant properties with excellent lubrication performance. HFD fluids are designed to operate in oil hydraulic equipment.
One automotive parts supplier decided to take the necessary actions to stop these events from happening, and engaged different departments within their organization to look for a solution.
To help improve operations, QUINTOLUBRIC® 888-46 was introduced as a potential replacement. First, Quaker Houghton helped the account to understand the advantages of changing from water glycol (HFC) fluids to QUINTOLUBRIC® 888-46 (polyol ester based HFD-U). These advantages include
QUINTOLUBRIC® 888 is a synthetic fluid that can be used in equipment designed for traditional mineral oil fluids and provides better performance than fluids containing water. In addition to fire resistance, the product provides excel¬lent biodegradability and low aquatic toxicity, making it ideal for use where better environment protection is required. It is approved by FM Global as a less hazardous hydraulic fluid.
To mitigate the risks of using a mineral oil based hydraulic fluid a large underground coal mine in southern West Virginia was using QUINTOLUBRIC® 888-68 an MSHA approved fire-resistant hydraulic fluid in their hydraulic systems.
To help mitigate the effects of the local water supply Quaker Houghton recommended the mine convert to QUINTOLUBRIC® 818-02, a full synthetic longwall fluid that can withstand the spikes in water hardness. Additionally, Quaker installed a new mixing station to filter the sediment from the water more effectively, and provide tighter controls on the longwall fluid concentration.
TAN merely measures the corrosive acids present in the fluid, and will increase over time as an indication of the deterioration of the fluid. However, different lubricant technologies such as mineral oil-based or polyol-ester-based hydraulic fluids and different additive technologies result in different TAN values
This document contains procedure guidelines for the conversion from both water free and water based hydraulic fluids to QUINTOLUBRIC® 888. The final procedure can change depending on local circumstances, and it is recommended to consult your local Sales Representative prior to starting the conversion.
Monitoring through in-service oil analysis, an important element of predictive maintenance, can provide informa-tion about machine wear, as well as lubricant contamina¬tion and condition.
The resistance to ignition and burning, termed fire-resistance in the hydraulic fluids field, is measured using a variety of methods. The techniques developed include laboratory testing methods, as well as simulations for possible industrial crisis situations.
