🔍 Key Concepts

• Heat generation in hydraulic systems during continuous operation • Role of an air cooled heat exchanger in maintaining oil temperature • Effects of high oil temperature on hydraulic components and seal life

💭 Think About

• In continuous service, what happens to the temperature of hydraulic oil if cooling is delayed or intermittent? • Which control method best keeps oil temperature within a safe, efficient operating range without over‑cooling or wasting power? • How critical is maintaining a relatively stable oil temperature for viscosity and system reliability?

✅ Before You Answer

• Identify which choice best ensures stable, controlled oil temperature during continuous operation • Consider which option would prevent overheating before it starts, not just react after shutdown • Check which answer aligns with typical design practice for industrial/continuous-duty hydraulic systems using air-cooled exchangers
