Protection against corrosion and rust. In other words, hydraulic oils are hydrolytically stable.
Optimal operations even under extreme working temperatures and conditions thanks to the viscosity stability of hydraulic oils.
Protection from foaming and formation of sludge and deposits. In return, the system's efficiency, reliability, and performance are increased.
Protection when the hydraulic system is exposed to air and water meaning that hydraulic oils possess anti-oxidation properties.
Filters of hydraulic systems maintain their filtration efficiency as hydraulic oils also serve as contaminants eliminators.
Hydraulic equipment is protected against water emulsion as the oil quickly separates water and prevents damage from occurring. This property is also known as demulsibility.
Some hydraulic oils are biodegradable and can be used in sensitive environments.
What Is Hydraulic Oil Used For?
Forklift trucks and stackers
To power the forks which lift heavy goods.
Wood (log) splitters
To power the ram mechanism on a hydraulic oil log splitter
Automotive lifts
Car lifts and car jacks require hydraulic jack oil to provide safety as well as performance.
Agricultural machinery and vehicles
To operate the hydraulic brakes and hydraulic systems such as boom arms.
NAUTICAL
For marine vessel stabilisers to reduce the amount of oil which can affect a ship’s balance and cause sea sickness.
Aircraft
Hydraulic oil must be reliable for control systems, aircraft hangar doors, aircraft jacks and aircraft controls.
Snow ploughs
An essential component in the operation of the hydraulic lift, tilt and angle movements, and blended with anti-freeze additives.
Construction
Used in a range of light, mid and heavy duty construction machinery such as cranes, excavators and tipper trucks.
Physical Properties Of A Hydraulic Oil
Hydraulic fluid is thermally stable, which helps retain its properties in a specific temperature range. The additives and hydraulic oil blend make it fit for using in both hot and cold conditions. Otherwise, high heat can lead to hydraulic oil deterioration.
Viscosity is the measurement of hydraulic oil’s flow resistance. It indicates that the oil can resist compression at different rates. High viscous hydraulic fluid is thicker and more difficult to compress, and low viscous hydraulic oil is comparatively thinner and quickly moves.
The hydraulic fluid’s viscosity is usually measured at 40°C to 100°C in the unit Centistokes (cSt). Hydraulic oil of different viscosity is used for different purposes because the wrong viscous fluid can damage the equipment or lead to poor functioning results.
The viscosity index measures the hydraulic oil’s viscosity when the temperature changes. The impact of temperature change is more on low viscosity index hydraulic oil than high viscosity index hydraulic oil.
The Society of Automotive Engineers (SAE) has developed a Viscosity Index Scale, presenting low to high viscosity levels based on different temperature ranges. It includes:
Low viscosity (0 – 35°C)
Medium viscosity (35 – 80°C)
High viscosity (80 – 110°C)
Very high viscosity (110°C and greater)
What Is Hydraulic Oil Made Of?
Mineral oil-based
Mineral oil-based hydraulic oil are the most common due to their relatively low cost and good lubrication properties. However, this type of hydraulic oil is susceptible to oxidation and thermal breakdown. Therefore, it is not suitable for high-temperature applications.
Synthetic oil-based
Synthetic oil-based hydraulic oil are created with chemically engineered compounds and have advantages over mineral oil-based hydraulic oil. They resist oxidation and thermal breakdown and are suitable for high-temperature applications. Also, they have excellent low-temperature performance, so that they can be used in cold environments too. This type of hydraulic oil is more expensive than mineral hydraulic oil.
Water-based
Water-based hydraulic oil are a mixture of water and additives, such as glycols or esters. These fluids have good cooling properties and work well in high-temperature systems. However, water-based hydraulic oil are unsuitable for systems with components susceptible to rust and corrosion.
