How Does Temperature Affect Hydraulic Systems?

Temperature directly affects hydraulic system performance and reliability.

High temperatures place stress on internal components and can lead to hydraulic system failure. Heat causes hydraulic oil and lubricants to lose viscosity, which can result in oxidation and reduced effectiveness at handling contaminants. This is common in equipment such as cranes and excavators that operate long hours in hot environments.

Cold temperatures also create problems by increasing fluid viscosity, slowing circulation, and reducing protection against wear. Cold weather can additionally make plastic seals brittle, increasing the risk of cracking or failure.

 

What is the Ideal Temperature for a Work Truck Hydraulic System?

The ideal temperature for a work truck hydraulic system is one that stays within a normal operating range and avoids extreme heat or cold. Hydraulic systems perform best when the oil can maintain proper viscosity and circulate freely without placing added stress on internal components.
