What is Hydraulic Fluid and How Can It Help in Hydraulic Systems? Hydraulic fluid is the transmission medium that is used in all hydraulic systems to generate the power needed to transfer energy from one source to another. The fundamental purpose of hydraulic fluid is that of a straightforward transmission of power, but it also has many other key purposes as well. Some of the secondary functions of it include heat transfer, contamination removal, sealing, and lubrication. Some of the key functions of hydraulic fluid are summarised below. •

Hydraulic fluid can help to shift excess heat away from components in hydraulic systems such as pumps and motors. This in turn helps to safeguard against overheating and protect against damage occurring to seals and internal components. Hydraulic fluid can move particles and water away from more delicate components using filters or other conditions, this helps to prevent oil staying within sensitive parts of hydraulic machines and defending against possible causes of contamination, which could lead to the damaging of machinery or sensitive components. Some types of hydraulic fluid can work as sealant within some of the internal components of hydraulic machines such as pumps, valves and motors. Certain hydraulic fluids can act as a lubricant, which can protect against metal-tometal friction, which is often a cause of wearing or even melting of internal components. This will help to ensure hydraulic machines stay efficient and reliable.

Types of liquids used as hydraulic fluid include: • • • • •

Mineral oil Water Phosphate Ester Water-based ethylene glycol compounds Silicone fluids

Three of the most common types of hydraulic fluids are detailed below. Petroleum-based This type of fluid contains substances that are mainly used to protect from oxidation and corrosion of components. This type of hydraulic fluid is most commonly found in a shipboard system. Synthetic Fire-Resistant This type of fluid is more commonly used in hydraulic systems where the potential of a fire risk exists, dues to its anti-flammable properties. Water-Based Fire-Resistant This type of fluid contains substances that can act as a lubricant, defoamer and corrosion inhibitor. It can also have up to 95% water, which makes it a very economical option.
