Question 121General Subjects - 1st Asst/Chief70% to pass
If a hydraulic pump is overheating, the cause may be _______________.
AI Explanation
The correct answer is D) excessive internal slippage in the pump.
When a hydraulic pump is overheating, it is often due to excessive internal slippage within the pump. This means that the pump is not able to efficiently transfer the fluid through the system, resulting in increased friction and heat generation. Excessive internal slippage can be caused by wear, damage, or improper clearances within the pump components.
The other answer choices are incorrect because:
A) Operation at 100% efficiency would not cause overheating.
B) An excessive fluid level in the reservoir would not directly cause the pump to overheat.
C) Low discharge pressure and fluid flow are more likely symptoms of the overheating issue, rather than the cause.
