What is a common result of localized hot spots in hydraulic systems?
What is a common result of localized hot spots in hydraulic systems?
- Rapid cooling of the liquid
- Carbonization or sludging of the liquid (correct)
- Increase in viscosity
- Formation of air bubbles
Why do liquids with high viscosity have a greater resistance to heat?
Why do liquids with high viscosity have a greater resistance to heat?
- Because they are more likely to break down when exposed to air
- Because they have a lower boiling point
- Because they are more dense and have a higher heat capacity (correct)
- Because they are more prone to chemical reactions
What is a common issue with the temperature of the liquid in the reservoir of an operating hydraulic system?
What is a common issue with the temperature of the liquid in the reservoir of an operating hydraulic system?
- It is not affected by localized hot spots
- It is always higher than the actual operating temperature
- It does not always represent the true state of operating conditions (correct)
- It is always lower than the actual operating temperature
