Question 301Motor Plants - Assistant Engineer

The correct answer is B) In this arrangement an independent pump is utilized. The explanation is as follows: 1) Confirm the correct answer: B is the correct answer. 2) Explanation of the reasoning: In a typical oil purifier system, an independent pump is used to supply oil to the purifier device. This pump ensures that the oil is circulated through the purifier at the appropriate flow rate and pressure, which is necessary for the proper operation of the separation process. 3) Explanation of why other options are incorrect: Option A is incorrect because the purifier does not have an attached positive displacement pump - it relies on a separate, independent pump. Option C is incorrect because the low-pressure in the suction piping is not the mechanism that supplies oil to the purifier. Option D is incorrect because the location of the purifier in the engine room does not determine how the oil is supplied to the device. 4) Concise summary: The correct answer is B because an independent pump, separate from the purifier, is used to supply oil to the oil purifier device.
