Hydraulic actuators are known for their efficiency over pneumatic and electric actuators. However, because they operate in highly rugged conditions, they are prone to frequent damage, especially on components. One of the components highly at risk is the hydraulic cylinder compartment, and hydraulics components Brisbane companies are looking for ways to mitigate the risk.

The Problem of Heat

High heat is the biggest threat to hydraulic cylinders. A hydraulic press has to operate in rugged conditions where high heat is generated. The optimal heat temperature that can be accommodated by these actuators is 100°F. There are scenarios where the maximum heat threshold exceeds 180°F, and can lead to mechanical complications.

Under high heat, hydraulic components are exposed to a number of threats. For instance, the hydraulic oil can lose its efficiency and property as a lubricant. Hydraulic oil can also oxidize under intense heat which leads to formation of sludge within the cylinder.

Sludge contaminates the oil leading to loss of effectiveness of the hydraulic cylinder. Wear and tear occurs under increased friction leading to damage of components. Oil leakage is also possible, which may cause harm to other components within the hydraulic system or pollution of the area the actuator is operating in. If the oil be flammable, it can lead to fire hazards that damage property or cause loss of life.

Solutions to Mitigate Heat

Hydraulic cylinder components companies are now forced to come up with solutions to alleviate the problem of heat. Presently, there are a few measures that have proven effective. One is to incorporate a second coolant that helps cool other parts of the hydraulic cylinder besides the oil within the chamber. This includes components like the piston, rod bearing, and rod seals.

A second measure taken by hydraulic cylinder repair experts is to replace the hydraulic oil. The hydraulic cylinder market now has what is called SLFI hydraulic oil that is more efficient compared to the older option. This fluid is highly fire resistant and has a low burn efficiency.

A third measure is to replace the sealant fluid with an advanced option that operates effectively under high temperatures. Currently, the hydraulic cylinder market has two sealant choices, viton and ethylene propylene, that are able to functions in temperatures as high as 350°F.

Final Remarks

Heat is a major problem that hinders the efficiency of hydraulic cylinders, and hydraulic cylinder repair companies have come up with three ways to combat the issue and restore efficiency to hydraulic actuators. The solutions include replacing hydraulic oils, replacing the sealant, and incorporating a second coolant to the hydraulic cylinder setup.
