WHAT IS A HYDRAULIC FLUID?
Hydraulic fluid, at its most basic definition is the medium responsible for lubrication, heat transfer & contamination control for hydraulic machinery. In a more general sense, it’s the fluid that makes it possible to transfer power and protect the equipment doing so. For hydraulic systems specifically, protection comes in many forms and covers; Anti-Wear, Oxidation & Thermal Stability, Corrosion and.
Disperse soot, varnish, and sludge in the oil.
Reduces friction (chatter, squeak); reduces micropitting on metal surfaces.
Prevents yellow metal corrosion on sensitive equipment and surfaces.
WHAT ARE HYDRAULIC FLUID CHALLENGES?
Hydraulic fluids are expected to deliver reliable performance 24/7 without breaking a sweat, however in the real world there are a few challenges that can present themselves. The most common of these are:
Contamination & Filterability
A properly formulated and maintained lubricant will withstand a majority of these challenges, but just like in any industrial there is no such thing as a perfect system.
HOW DOES A HYDRAULIC SYSTEM FAIL?
There are multiple methods that a hydraulic system can fail, and be awaring of each during product development can help prevent poor performance. The most common failure methods for hydraulic systems are:
Surface Degradation & Cavitation
Mechanical Wear & Abrasion
Corrosion & Rust
If any combination of these issues are experienced, it can cause varying levels of inefficiencies or ultimately catastrophic failure. It is vital that the fluid is engineered for the particular environment and operating conditions for the application. By using the right additive technology you can minimize or even eliminate some of the potential risk.
