Making Renewable Energy "Greener"


Published on

Renewable Energy - Wind, Hydro, Solar - are technologies that we feel good about. The environment needs it and we need it. However, there are challenges to the reliability and economy of these technologies that must be met. Discover how oil analysis and contamination control can improve reliability and extend life of critical components.

Making Renewable Energy "Greener"

  1. 1. Making Renewable Energy GREENER with Oil Analysis and Contamination Control I. The Importance of Analysis and Filtration II. Case Studies III. Questions and Answers
  2. 2. Renewable Energy is Important to C.C.JENSEN Our Wind Turbine covers 40 % of our energy consumption The Importance of Analysis and Filtration
  3. 3. Renewable Energy is Important for Many Reasons… it’s Clean, Available, and Provides Security. The Importance of Analysis and Filtration
  4. 4. The Importance of Analysis and Filtration WIND TURBINES – Pushing the Design Envelope BLADES 120 m (394 ft) Extreme pressure on components 2 million N-m (1,475,000 lb-ft)
  5. 5. The Importance of Analysis and Filtration PITCH HYDRAULIC GEARBOX MAIN BEARING Extreme pressure on components CLEAN OIL GETS MORE AND MORE IMPORTANT BLADES 120 m (394 ft)
  6. 6. THE IMPORTANCE OF CLEAN OIL AND IT’S IMPACT ON RELIABILITY HAS BEEN KNOWN FOR DECADES “Replacing 40-25µm filters by units rated at 3µm absolute is to be recommended for gearboxes. Such action should lead to improved reliability, longer periods between overhaul, cheaper overhauls, and consequent reductions in ownership costs. Times between oil changes, where relevant, should be substantially increased.” 1979 The Influence of Filtration on Rolling Element Bearing Life Source: R. Bhachu, R. Sayles, and P.B. Macpherson The Importance of Analysis and Filtration
  7. 7. Ref: NORIA The Importance of Analysis and Filtration Did You Know? The estimated gearbox failure in a Wind Turbine is estimated at $250,000!
  8. 8. The Importance of Analysis and Filtration “Bearings Don’t Fail… They’re Murdered” Ref: NORIA
  9. 9. IMPROVED FILTRATION IS ABLE TO KEEPTHE OIL CLEAN AND MAKE IT LAST LONGER LESS USE OF FOSSIL OIL LESS TRANSPORTATION LESS WASTE OIL The Importance of Analysis and Filtration Did You Know? The estimated cost of an oil change is $5,000 on a Wind Turbine.
  10. 10. The Importance of Analysis and Filtration Every Barrel Counts… 16,000 Wind Turbines X 100 Gallons = 29,090 Barrels Three-Year or Six-Year Oil Service Life – Which is GREENER?
  11. 11. OXIDATION WATER PARTICLES Oil Analysis Reduces Maintenance and Downtime! The Importance of Analysis and Filtration
  12. 12. The Importance of Analysis and Filtration End of Section I Take Away: No machine has ever failed because the oil was too clean; What get’s measured get’s done. Question: What is the most important parameter on your oil analysis test slate?
  13. 13. Case Study – Hydro Power
  14. 14. Case Study – Hydro Power “We sampled using the procedure and the iso(c) code came back as 13/11/8. That’s the cleanest our oil has been in years!”
  15. 15. Case Study – Hydro Power Used Filter Ideal for Filter Debris Analysis
  16. 16. Case Study – Hydro Power Filter Debris Analysis
  17. 17. Case Study – Wind Power “The oil at [our project] is the exact opposite of the [clean] oil, its beyond filthy!! We should have taken out disaster insurance on it…you would not believe or want to see what comes out of one of these when you turn it upside down. Well, maybe you would. It was the most disgusting, revolting lumpy stinky slime I’ve ever seen come from the bowels of the gearbox.”

  22. 22. Case Study – Wind Power PROBLEM •After 2 years using O.E.M 10-micron in-line filter – particle count + 500,000 4-micron particles per/100 ml. ISO 20/18/15 SOLUTION HDU 15/25 PV2-7-4 1x120V, 60hz incl. air bleed hose Filter Insert: BG 15/25, 3 μm absolute filtration Pump flow: 57 L/h “Since [upgrading our filtration] our oil analysis has showed considerable improvement, and our gearbox has yet to have a single bearing failure, vibration analysis alarm, or high-heat signature. We are likely to save major repairs – that may cost over $900,000” Date 11/07/2010 01/24/2011 02/25/2011 > 4 micron 591,500 129,200 42,800 > 6 micron 230,000 50,300 16,600 > 14 micron 17,400 3,800 1,200 ISO Code 20/18/15 17/16/12 16/15/11 591500 230000 17400 129200 50300 3800 42800 16600 1200 > 4 micron > 6 micron > 14 micron 11-07-2010 01/24/2011 02/25/2011
