Industrial hydraulics: main considerations and guidelines

Industrial hydraulics: main considerations and guidelines

While operating hydraulic equipment, a schedule of operating liquid analysis must be established. Another important point is to define all potential weak spots where contamination may enter the system. Dissemination of operating liquid analysis results in various stages of operation allows to promptly respond and improve filtration of the liquid, maintaining efficiency of the machinery.

Contamination is especially dangerous to hydraulic systems because it is not directly visible by the naked eye. The danger of the seemingly harmless components should be clearly understood.In most cases the solid particles which can damage hydraulic systems are smaller than 10 micron, while the naked eye can only see particles 40 micron and larger.

Each facility should maintain a professional whose responsibility is to monitor the condition of operating liquid. Specifically, such person should be responsible for the following:

  1. sampling of supplied liquid from the manufacturer
  2. analysis of such sample for presence of contaminants using special lab equipment
  3. knowledge of the purity requirements
  4. ability to correctly introduce the liquid into the hydraulic system
  5. understanding of causes of contamination and knowledge of point where contaminants may enter the hydraulic system.

In general, 70 to 80% of hydraulic system failures are caused by contamination.Understanding of the origins of contamination can prevent such failures.Liquid received from the manufacturer must comply with certain requirements. It must be transported in clean vessels.
