Hydraulics Learning Sessions
Brian Thorp – PdM Tech III, Seminole Electric Coop
Have you ever been frustrated with the maintenance and management of your phosphate-ester lubricant? If so, this presentation is one you will not want to miss. Phosphate-ester lubricants are commonly used in electro-hydraulic control (EHC) systems for power generation and other high-temperature industries because of their fire-resistance and self-extinguishing properties. They are also considered to be some of the only “for-life” lubricants if properly managed. This case study will cover 16 years of 4,800 gallons of EHC fluid, including the different filtration methods, acid remediation media, and the current system conditions. Attendees will gain insight into what worked, what didn’t, what special tests were performed and the issues that occurred after the flush and oil change.
Hank Ayers – Instructor/Consultant, GPM Hydraulic Consulting
Predictive maintenance is a strategy that encompasses immediate, often simple measures to add to existing maintenance tasks that can greatly reduce downtime. This session is about those simple steps you maybe never knew about, maybe needed a little more clarification or perhaps just tend to overlook. You’ll learn the basics of proper contamination control, hose repair, temperature checks, sound checks, pressure checks, pipe clamping and more. Discover the value of field inspections that require just a few moments and your own observational skills. It could save you lots of time and money in the long run.
Jaime Contreras – Innovation and Development Manager, Ripipsa
There are many misconceptions in industrial hydraulics, many of which may lead to premature component failures, unnecessary component replacement and consistent underperformance in machine efficiency and reliability. This session will address the most common hydraulic misconceptions and the problems they produce. You’ll learn how to recognize if pressure valves are properly adjusted, the difference in performance of directional valves, the proper use of hydraulic accumulators and how to interpret/utilize hydraulic symbols correctly.
Doug Sackett – District Manager, Total Lubricants
Most lubricant buyers seek to lower production costs, and this frequently translates into spending as little as possible on fluids. With so many hydraulic fluid producers in the market, it’s easy to find products that claim to get the job done and are light on your budget. However, it can be difficult to determine which product truly suits your needs. This session will look at all the requirements of hydraulic fluids and the different classifications that can either enhance your equipment reliability or damage it. You’ll leave knowing how to read data sheets and ask the right questions, so fluid selection will yield the results you want.
Tony Casassa – Application Engineer, Aggressive Hydraulics
When repairing or replacing hydraulic cylinders, it is critical to consider contamination and cleanliness. For some industrial facilities, this means implementing procedures to ensure cleanliness. For others, it means finding a cylinder company that has a cleanliness program already in place. In this session, follow the journey one manufacturer took to maintain cleanliness and provide clean hydraulic cylinders to its customers. Attendees will learn how ideas were generated and implemented, how results were communicated throughout the company, what the company’s current state of cleanliness is and what steps the company plans for improvement.
Doug Muennich – Business Development Manager, RelaDyne
Hydraulic oils are subjected to increased thermal and mechanical stresses in modern hydraulic systems, resulting in system deposits, fluid failure and equipment reliability issues. This presentation will explore the various mechanisms causing hydraulic fluid degradation and the most effective methods for detecting and avoiding premature fluid failure. Doug Muennich will explain the impact of oil oxidation and varnish formation in hydraulic systems and why inadequate oil analysis testing is the main reason hydraulic oil users experience problems with their fluids. Don’t resign yourself to lubricant failure because your system operates at high temperatures. Find out how you can extend the life of your hydraulic fluids and save time and money with more reliable machinery.
Mrinal Mahapatro – Senior Engineer, Pall Corporation
Varnish is a significant problem in modern industrial hydraulic systems. It can cause severe operational issues by plating out on metallic surfaces such as valves or cylinders, leading to valve stiction, sluggish control and longer response times. Varnish can also plug last-chance filters (LCFs), resulting in short filter service life. In this presentation, attendees will learn what varnish is, how it affects hydraulic systems and fine filtration, and what the most trusted methods are for safely removing it.
