Have an idea for a newsletter topic? Contact us.

We are pleased to share with you our second newsletter that offers a fresh perspective on technical issues facing the industry.

Our goal is to provide relevant information that you can use to improve reliability and profitability in your company. Despite the overall sophistication of modern lubricant and fluid maintenance practices, most oil analysis programs are missing important information that limits your ability to gauge the effectiveness of existing programs. In this issue you will find answers on fluid resistivity management, and common challenges in Electro-Hydraulic Control (EHC) systems.

Thank you for your interest.

New Website!

We have launched our new website – cleanoil.com. We have taken a different approach, focusing on lubrication and fluid issues and how to solve them. We look forward to your feedback.

Left Over Budget Money?

It’s that time of the year, when you may find yourself with left over money in your annual maintenance budget. This is the perfect time to upgrade your lubricant filtration system or oil analysis program. For example, highly effective and low cost water removal systems, such as our TMR™ N2, offer immediate payback and high ROI. In addition, our prepaid oil analysis kits offer comprehensive analysis to supplement existing programs and to help identify problem areas.

Resistivity, Fact or Fiction?

Resistivity is a critical performance indicator for phosphate ester (PE) fluid quality.

Low resistivity values are associated with electro kinetic wear, a common failure mechanism of servo valves. For decades, users have struggled with maintaining high resistivity over time using a variety of filtration techniques, fluid replacement and sweetening.

In our ASTM paper entitled “Phosphate Ester-based Fluid Specific Resistance: Effects of Outside Contamination and Improvement Using Novel Media,” we demonstrated that widely used alumina-based adsorbents (ABA, e.g. Selexsorb® GT) produce artificial increases in resistivity that can be reversed with filtration. In contrast, the use of ion exchange resin technology, which has historically shown mixed results, is proven to be highly effective at producing authentic increases in resistivity when specific resin types and combinations are used.

Conventional filtration methods, such as ABA, were shown to release aluminosilicate particle contaminants, which artificially increase PE fluid specific resistance. Specialized ion exchange technology media is demonstrated to truly extend the life of PE fluids through proper conditioning, without the addition of deleterious contaminants.

Not all ion exchange resins are created equal, with proprietary formulas, specifically EPT’s ion charge bonding (ICB™) media, providing superior performance.

Four Tips to Solving Phosphate Ester Testing and Maintenance Challenges in EHC Systems

Despite the excellent lubricating and safety properties of phosphate ester lubricants, many gas turbine and Electro-Hydraulic Control (EHC) users struggle with their maintenance. Below are four tips that can greatly improve your PE fluid testing and maintenance program.

1 - Improve Fluid Testing: Standard lab analysis is missing key information necessary to manage PE fluids. Dissolved contaminants that are responsible for servo-valve sticking are not reported as part of standard lab analysis program. In addition, metals are also overlooked and play a key role in determining the rate of fluid breakdown as well as varnish formation.

2 - Remove the Hidden Contamination Responsible for Valve Sticking: EHC fluid maintenance must be designed to remove the contamination responsible for mechanical issues. You may be surprised to learn that the dissolved contamination responsible for servo-valve sticking is not removed with normal acid removal filters. In addition, many of these filters not only contribute contamination, but interfere with resistivity values, suggesting to users that maintenance practices are working better than they really are.

3 - Remove Water and Prevent Atmospheric Contamination: EHC fluid maintenance must manage the factors that cause fluid breakdown. Heat, water, oxygen, and metals determine the rate of oxidation and, therefore, the rate at which EHC fluid breakdown occurs. Unless managed, these factors result in higher than desired rates of EHC fluid breakdown. Existing fluid maintenance does not generally manage these variables.

4 - EHC System Review and Fluid Monitoring: EHC system operating practices often accelerate fluid problems. Flow rates, operating temperatures, fluid operating levels and mechanical system component operation all need to be reviewed so they are not unnecessary contributing to EHC fluid break-down.

Looking to understand best practices in lubricant management in a vendor-neutral environment? Join us for the third in a 3-course series dedicated to providing you with the practical knowledge you need to optimize your lubrication management.

Oil Analysis and Report Interpretation.

Modern production equipment requires sophisticated lubrication management to ensure reliable, safe, and efficient operation. EPT, in conjunction with Lubeworks, is pleased to offer the third installment of their three, one-day courses that are open to the public. This specialized training offers an ideal opportunity for lubricant users to increase their knowledge and skills so they can perform their responsibilities with a higher level of understanding and expertise.

Knowing how to implement or improve a lubricant management program is critical to the success of your operation and we will strive to give you practical and efficient ways of implementing these practices. These classes are offered at our world-class training center where users can learn with their peers in a vendor neutral environment.

Please view our training brochure to the left for details on what you will learn in this installment of the series.
