Question 36Motor Plants - QMED

The correct answer is B) reprime the purifier with sealing water. When fuel oil is being discharged from the waste water outlet of a fuel oil disk type centrifuge, it indicates that the centrifuge is not properly separating the fuel oil from the water. This issue can be resolved by repriming the purifier with sealing water, which helps to create the necessary seal and ensures the proper separation of the fuel oil and water. The other options are incorrect because: A) removing the discharge ring would not address the underlying issue of improper separation; C) slowing the centrifuge to its proper speed may not be sufficient to resolve the problem; and D) installing an additional discharge ring would not directly address the issue of fuel oil being discharged with the waste water.
