Dongguan oneness filtration technology co., LTD. : what are the functions of oil filters (III)

Author:admin      2019-09-04

  3, fine filter: the function is to filter out smaller impurities in the lubricating oil, usually in parallel with the main oil channel, there are centrifugal and paper board.
  4. The structure of centrifugal filter: the hollow rotating shaft is fixed on the shell, the rotor body and end sleeve are connected as a whole, which is located on the thrust bearing and can rotate freely around the rotor shaft. A compression nut fastens the rotor cover to the rotor body, which is compressed with a spring to limit the axial movement of the rotor. Two mutually opposite nozzles are installed below the rotor. When the engine is running, a small part of the oil is pumped from the pump and enters the filter through the oil port. When the oil pressure is lower than 9s kpa, the inlet pressure limiting valve closes and the fine filter does not work. When the oil pressure exceeds 98 kpa and the pressure limiting valve opens gradually, the oil will be ejected from the oil outlet through the hole in the center of the rotor shaft. Then through the oil hole into the rotor, and ejected from two nozzles, the jet reaction force is to promote the rotation of the hand. When the oil pressure rises to 294 kpa, the rotor speed can reach more than 5000r/min, and the proportion of impurities in the lubricating oil in the rotor cavity is larger than that of the lubricating oil. Under the action of rotating centrifugal force, it is thrown to the rotor wall and attached to the wall with a cover. Clean lubricating oil at the center enters two nozzles from the center and continuously sprays outward. The sprays flow back to the lower crankcase.
