What happens when a hydraulic system operates with fluid temperature that exceeds the normally recommended maximum of 180° F? A model was developed to study thermodynamic behavior of a hydraulic system in a garbage truck that can also be applied to hydraulic systems on other work trucks. Acharacteristic some-times overlooked with hydraulic systems on industrial trucks, such as garbage trucks, is what happens when they operate at high fluid temperature. High fluid temperature can degrade the fluid, cause premature failure of components, rob system performance, and even pose safety hazards to personnel.
