One of the nest preventive maintenance tasks you can perform for your hydraulic equipment is contamination control. >>> link to previous article, Benefits of Fluid Filtration Maintenance <<< This involves preventing contaminants from entering hydraulic systems. Placing filters at strategic locations throughout your system will help filter out any contaminates that do find their way into your valuable hydraulic systems. This is where Tiocco can help by providing you with a state of the art filtration system installed directly in your hydraulic systems reservoir to attack the storehouse of fluid contamination >>> link to previous article, The Why and How Tiocco Removes Liquid Contaminate and Why Normal Filters Can’t <<< designed for the specifications of your system. Your successful contamination control system will contain provisions for having the fluids tested for contaminants. Most experts recommend hydraulic fluids be analyzed for contamination every two to six months or every five hundred to one thousand hours of operation; depending on the workload and operating environment of your hydraulic system. It is also highly recommended that hydraulic fluids be tested following any intrusive maintenance or repair procedure. This would include the replacement of a hose, valve or other procedure that exposes the fluid to external environment. Oftentimes contaminants are introduced into your delicate hydraulic system by merely replenishing fluid levels. This is due usually to poor handling and or storage practices.

When sampling your fluids for testing, it is imperative to maintain the environment as clean as possible. A fluid sample introduced into a vessel that itself contains contaminants will produce faulty, undesirable results.

It has been common practice when collecting fluid samples to NOT take the sample from a reservoir. Fluids in reservoirs tend to have been collected over a relatively longer period of time and are far more likely to contain contaminants, thereby producing false results. This is the exact reason that Tiocco recommends installing their systems in the reservoir and recommends taking samples from the same. The contamination in the reservoir that other filter manufactures avoid is the source of the degradation of the hydraulic fluid and the entire hydraulic system.

When your sample arrives at the lab, chemists will perform the necessary testing using several different, although not all approaches. Some of the more popular testing approaches are:

  • Particle distribution
  • Gravimetric
  • Ferrographic wear debris
  • Proton induced X-ray
  • Water content

Water glycol hydraulic fluid will have these other testing approaches relative to this type of fluid:

  • Percent tramp oil/Varnish
  • Color and/or clarity
  • PH
  • Reserve alkalinity

These tests will each provide their own specific data in accordance with the information sought. They should not be viewed as competing tests but rather a battery of tests being performed on the same sample, each with its own revealing sensitive information. This information could prove very valuable to the life, dependability and performance of your critical hydraulic system.
