Solving Hydraulic System Overheating Problems

Hydraulic fluid temperatures above 180°F (82°C) damage most seal compounds and accelerate degradation of the oil. While the operation of any hydraulic system at temperatures above 180°F should be avoided, fluid temperature is too high when viscosity falls below the optimum value for the hydraulic system’s components. This can occur well below 180°F, depending on the fluid’s viscosity

Effects of Temperature on Hydraulic Systems - MAC Hydraulics

02.08.2019· Effects of High Temperatures on Hydraulic Systems. When hydraulic fluids and lubricants are exposed to high temperatures for extended periods of time, the fluids will begin to experience permanent deterioration and a severe reduction in viscosity (i.e., the fluid will be much thinner and less viscous). The deterioration of hydraulic fluid leads to oxidation (in fact, the oxidation rate …

Common Causes Of Hydraulic Overheating - CrossCo

It is important to remeer that hydraulic fluid is critical to protection of the metal components in any system and its degradation will lead to shorter component life. While good design techniques can be employed to reduce overall heat load in a system, it is generally a mistake to believe that good design alone can prevent overheating in the absence of a cooler. Learning what causes
