What will overheating do to my hydraulic oil ?

How hot is too hot for a hydraulic system? It depends mainly on the viscosity and viscosity index (rate of change in viscosity with temperature) of the oil, and the type of hydraulic components in the system. As the oil’s temperature increases, its viscosity decreases. Therefore, a hydraulic system is operating too hot when it…

What is the main purpose of Hydraulic Fluids?

The primary function of a hydraulic fluid is to convey power. In use, however, there are other important functions of hydraulic fluid such as protection of the hydraulic machine components. Lubrication: Hydraulic fluids must provide the lubricating characteristics and qualities necessary to protect all hydraulic system components against friction and wear, rust, oxidation and corrosion.

What is Viscosity and why is it important?

The viscosity is the property of a fluid that resists the force tending to cause the fluid to flow. For liquids, it corresponds to the informal concept of “thickness”. For example, honey has a much higher viscosity than water. The viscosity usually depends on its composition and temperature. For gases and other compressible fluids, it…

Is brand new oil clean?

They say that seeing is believing. They also say, don’t believe everything you see. Contradicting huh? Well the same is true of new oil. An unopened barrel of oil straight from the supplier ought to be pretty clean right? Wrong! In fact, new oil has an ISO cleanliness code of around 20/18/15. This is just…

How to take an oil sample

Oil samples should be taken on a regularly scheduled basis and should only be taken after the lubricating system or component has been operated long enough to reach operating temperature. This will ensure that the oil has been thoroughly circulated and will result in an oil sample that is truly representative of the oil in…

Why check your oil?

The cleanliness of hydraulic oil systems is extremely important because of the very close tolerances that exist in the pumps, control valves and between the pistons and hydraulic cylinder walls. In fact, around 80% of hydraulic system failures are caused by contamination through dust, dirt and condensation moisture. Therefore, oil analysis should be performed on…
