What can result from hydraulic fluid temperature being excessively high?

When hydraulic fluid temperature rises excessively, one significant risk is the occurrence of cavitation and potential component failure. High temperatures can lead to vapor formation in the hydraulic fluid, which disrupts the consistent pressure required for effective operation. Essentially, cavitation occurs when the local pressure of the fluid drops below its vapor pressure, causing bubbles to form. These bubbles can implode, resulting in shock waves that can damage pumps, valves, and other hydraulic components.

Moreover, excessive heat can also degrade the chemical properties of the hydraulic fluid, leading to oxidation, reduced lubrication effectiveness, and the formation of sludge, which further compromises system reliability and performance. Thus, managing fluid temperature is crucial for preventing cavitation and ensuring the longevity and efficiency of hydraulic systems.
