7 steps to hydraulic cleanliness

14.04.2021 | Hydroline

Manufacturing hydraulic cylinders requires specific processes to prevent a cylinder from contributing failure to other system components. It is a common scenario that microscopic solid particles can cause a component failure for machinery using hydraulic systems. According to industry experts, contamination causes approximately 60% to 90% of all hydraulic system failures. The malfunction may be intermittent and requires extensive troubleshooting to identify the faulty component.

How to design a hydraulic cylinder?

17.02.2021 | hydroline

The hydraulic systems date back as far as over 4,000 years ago in Ancient Egypt. They initially applied the principles of fluid hydraulic to the complicated canal systems used in watering. Other civilizations, including the Greeks and Romans, used the same basic principles to develop water-powered structures and devices like the water clock and water wheels. Since then, the fluid power universe has become a little more complicated. Fluid power has been used for Centuries to create energy to generate movement and force.

While working in the hydropower industry, most probably you have stumbled upon the term ISO 4406? What the code is referring to is ISO 4406:1999 standard for oil cleanliness. In 1999, The International Organization for Standardization developed a system ISO 4406:1999. This system rate and quantify the number of particulate contamination levels per milliliter of fluid at three sizes; larger than 4-, 6-, and 14 microns.
