🔍 Key Concepts

• energy loss as heat in hydraulic systems • role of a pressure relief valve in controlling system pressure • how continuous leakage or bypass flow affects oil temperature

💭 Think About

• Which option describes a condition where fluid is constantly being forced across a restriction, turning pump work directly into heat? • In normal operation, do load variations alone usually cause severe overheating, or does overheating come from an abnormal, continuous loss path? • Think about whether each choice would be a brief/occasional event or a continuous condition that wastes power and heats the oil.

✅ Before You Answer

• Identify which choice involves continuous flow under high pressure that does not do useful work. • Eliminate any options that sound like normal operating behavior rather than a fault or abnormal condition. • Ask yourself: In which option is the pump’s output mostly being converted into heat instead of useful hydraulic work?

Overheating of the oil in a hydraulic system can be caused by __________.

insufficient external pump slippage

fluctuating pump discharge pressure in response to normal load variations

continuous leakage through the pressure relief valve
