🔍 Key Concepts

• Heat generation in continuous-duty hydraulic systems • Difference between intermittent and continuous operation • Effects of high flow rate and pressure on oil temperature

💭 Think About

• Which of these systems is most likely to run for long periods under load, not just in short bursts? • Which system would generate the most continuous heat in the hydraulic oil because of frequent or constant adjustment or motion? • Which systems are typically operated only occasionally, so the oil has time to cool between uses?

✅ Before You Answer

• Identify which option involves continuous or frequent operation under varying load • Consider which system’s failure due to overheating of oil would most affect safety and performance • Eliminate systems that are normally used only briefly or infrequently, producing limited heat in the oil
