When you choose the hydraulic fluid in UAE , stability, viscosity and corrosion are the main things that you should consider.
The demands given on hydraulic systems continuously updated with an increase in efficiency and speed at a superior level of operating temperature and pressure. If you want to choose a best hydraulic fluid, you need to understand the characteristics of each fluid that includes thermal stability, hydrolytic stability, less amount of chemical corrosiveness, superior level of anti-wear characteristics, low tendency to cavitate, durable, total water rejection, constant viscosity, regardless of temperature, and affordable price.
You can't find all your required things in one fluid, but yes it is possible you can get the best compromise for a particular system. Here also you require the proper knowledge of the system in which you want to use the fluid.
THINGS THAT INFLUENCE HYDRAULIC PERFORMANCE
VISCOSITY — Fluid's viscosity depends on the maximum and minimum operating temperature that also includes system's load. Even at the maximum operating temperature, the fluid must maintain a low amount of viscosity.
WEAR — Generally wear and friction considered together, so wear is misunderstood in most of the cases from all the hydraulic system problems. Friction is also a different thing compared to wear.
With metal-to-metal contact, wear comes in the picture. If you are planning to minimize metal breakdown with the help of protective additive, then it's really critical. While in contrast, friction is reduced if you use fluid at the time of metal-to-metal contact. Oil makes an additive film between moving metal parts.
ANTI-WEAR — Zinc dithiophosphate (ZDP) is the common hydraulic fluid but at the places where the metal content in any wastewater from manufacturing processes must be minimized, anti-wear fluid performs the best. In the formulation process of the ashless anti-wear fluids, no ZDP or another type of heavy metals have been used.
FOAMING — If the foam comes with the fluid, it generally degrades the performance of the system, so it needs to be eliminated. By providing a proper solution to the air leaks, you can prevent this problem. But still, some general types of foams such as surface foam and entrained air still occur frequently.
There are multiple types of hydraulic fluid available in the market. So first understand the requirement of your system and then choose the best fluid for it. You can also ask the experts for the better choice.
