Question 113Motor Plants - 1st Asst/Chief70% to pass
As Chief Engineer of a slow-speed diesel engine vessel equipped with an ALCAP fuel oil purification system. You note a definite increase in the rate at which the purifier sludge tank is rising. One of the first items to check on your system would be which of the following?
AI Explanation
The correct answer is A) The opening water solenoid for leak through.
The reasoning is that a definite increase in the rate at which the purifier sludge tank is rising indicates an issue with the water separation function of the ALCAP purifier. One of the first things to check would be the water solenoid valve, as a leak through this valve could allow excess water to enter the system, leading to an increased sludge buildup.
The other options are not as directly relevant to the issue described. Checking the water transducer, the RPM of the bowl, or the voltage to the control cabinet may provide additional information, but addressing a potential leak in the water solenoid should be the first step in troubleshooting the purifier problem.
