MDE Unit 11 Q3 – Answer

Components:

  1. Oil Inlet: Port where the dirty lubricating oil enters the filter.
  2. Rotor: Rotating element within the filter housing.
  3. Vanes: Blades on the rotor that help impart centrifugal force to the oil.
  4. Filter Housing: Enclosed chamber containing the rotor and other components.
  5. Clean Oil Outlet: Port where the filtered lubricating oil exits the filter.
  6. Contaminant Collection Chamber: Area where separated contaminants accumulate.
  7. Drain Plug: Allows for removal of collected contaminants during maintenance.

Operation:

  1. Dirty lubricating oil enters the filter through the oil inlet (1).
  2. The oil flows into the rotor (2) chamber.
  3. The rotor spins at high speed due to an external power source (not shown).
  4. As the rotor spins, the oil is subjected to centrifugal force. This force pushes denser particles like wear debris and dirt outwards, away from the oil.
  5. The vanes (3) on the rotor help to further distribute the oil and increase the effect of centrifugal force.
  6. The cleaner oil, less dense than the contaminants, remains near the center of the rotor.
  7. Clean oil exits the filter through the clean oil outlet (5).
  8. Denser contaminants like wear debris and dirt are forced outwards and accumulate in the contaminant collection chamber (6).
  9. The drain plug (7) allows for periodic removal of collected contaminants for maintenance purposes.
