Question 524Steam Plants - Assistant Engineer70% to pass
In steam turbine and reduction gear units, lube oil coolers installed in the lube oil system are located between the _______________.
AI Explanation
The correct answer is A) lube oil pumps and gravity tanks.
In a steam turbine and reduction gear unit, the lube oil coolers are typically installed between the lube oil pumps and the gravity tanks. This placement allows the lube oil to be cooled after it has been circulated through the bearings and other components, but before it enters the gravity tanks. This helps to maintain the proper temperature of the lube oil throughout the system.
The other options are incorrect because:
B) The lube oil sump is the source of the lube oil, not the location of the coolers.
C) The gravity tanks are located downstream of the coolers, not between the coolers and the sump.
D) The gravity tanks are not located between the coolers and the main unit.
