Centrifugal oil filter is composed of the shell and filter cover, rotor shaft, rotor and rotor cover.

In this case,Rotor shaft fixed to the filter housing, the rotor body pressure has three bushings and should be connected with the rotor shaft end, set in the rotor shaft can be free to rotate. Compression nuts fasten the rotor cover and rotor body together, and then through the dynamic balance test. Underneath the rotor is a thrust bearing with a bearing pad on it and pressed with a spring to limit the runout of the rotor shaft.

The lower end of the rotor has two horizontally mounted opposite nozzles. Filter cover and the shell has a high degree of neutrality, so that the rotor reaches a certain speed, in order to ensure the quality of the oil filter. The filter cover is mounted on the filter housing with a compression nut to seal the rotor.

Centrifugal oil filter works

When the engine is working, the oil from the oil pump enters the oil filter hole. When the first oil pressure 0.1MPa, the oil pressure limiting valve opens, the oil along the shell and rotor shaft center hole through the oil hole into the rotor cavity, and then by the oil from the two nozzles. 

Under the impetus of oil jetting reaction, impurities in the oil are dumped on the inner wall of the rotor cover and precipitated, and the clean oil flows to the oil pan through the oil hole.
