BFPA Technical Conference Focuses upon the Importance of Fluid Purity and Cleanliness in Hydraulic Systems
BFPA CEO Chris Buxton reports on the forthcoming BFPA technical conference and invites all readers to attend the event which is being held in Bath on the 10th and 11th of September 2018
Like the ‘lifeblood’ that pumps around the human body, every fluid power engineer knows that the Hydraulic Fluid in a Fluid Power System is crucial to both the health of the system and the performance of almost every aspect of the equipment. All too often, operatives spend vast amounts of time calibrating and adjusting their equipment to ensure optimum system performance and yet they don’t take equal care to ensure the purity and cleanliness of the all-important Hydraulic Fluid that resides at the very heart of the system. Of all of the oil-lubricated systems in commercial and industrial facilities, hydraulic systems are, by far, the most sensitive to contamination.
For particle contamination, the big concern is silt-sized particles in the 1-micron to 10-micron size range. While tiny — less than 1/10th the thickness of a human hair — 3-micron silt-sized particles, which are no bigger than a red blood cell, are as much as five to ten times more likely to cause failure. That’s because many filters are not designed to remove such small particles, coupled with the fact that dynamic clearances (the separation between moving parts under operating load, speed, and temperature) in pumps and valves are typically in the 1-micron to 5-micron size range.
After hard particle contamination, water is the second most damaging contaminant found in hydraulics. Present in most fluids even in the cleanest environments, water can increase failure rates 10-20 fold depending upon the circumstances. Water causes problems in a number of ways — first, any iron or steel surface in contact with water will, of course, start to rust. This can induce premature failure due to corrosion, as well as introduce rust particles into the fluid.
These issues and a host of related contamination spawned scenarios (and how to avoid them), will be
50 LUBE MAGAZINE NO.146 AUGUST 2018
the subject of a forthcoming Technical Conference being run by the British Fluid Power Association with the support and sponsorship of the United Kingdom Lubricants Association (UKLA). Planned to be held at the University of Bath, the event will take place over two days on the 10th and 11th of September 2018 and will include an informal networking dinner on the evening of the 10th September. The event will also include a small table top exhibition of interested equipment and service providers. Immediately following the BFPA Conference (12th, 13th and 14th of September on the same site), will be the Bath University Annual Symposium on Fluid Power and Motion Control: FPMC 2018. This international Symposium provides a forum for leading-edge activities in the field of fluid power and motion control. The Symposium should be of great interest and value to all practitioners and researchers in the fluid power, power transmission and motion control community. To this extent, attendees of the BFPA event may also wish to consider staying-on and attending both conferences.
The BFPA Executive and Board along with their colleagues at the UKLA would encourage all readers who have any involvement with Fluid Power Systems to seriously consider attending the two day BFPA Conference and are pleased to add that special rates are being made available for UKLA and BFPA members.
