Centrifugal fine filter structure is complex, there are high-speed moving parts, high maintenance technical requirements. Therefore, pay special attention to the following maintenance. 

     A familiar structure, correct disassembly
     Must first understand the structure, components and assembly assembly relationship between the mark. In the demolition process, certain parts must be examined to determine whether to continue to use.
     2, thorough cleaning parts
     The inner wall of sludge oil wash cleaner, then wipe with clean cloth or blowing with compressed air. The inner wall of bearing no.f82225 the rotor precipitate first scrape with a wooden knife, and then cleaning the oil will rotor vivo washed, and then wipe with a clean cloth or blowing with compressed air. The rotor copper pipe dredge nozzle body can net oil first, and then compressed air to blow through. After washing the oil filter on the injector tube, and then compressed air blowing. Note: When cleaning, do not clean the sealing pad.
     3, assembly essentials
     (1) after the assembly of the marker assembly is
     Rotor speed up to 5000r / min or more, the higher its balance requirements. When assembling the rotor body and the rotor cover must be on the corresponding symbol. If you do not pair, or in the interior of the rotor to clear the precipitate, which is not a metal blade with a chisel or hard to scratch the rotor apparatus, will destroy the balance of the rotor, the acceleration of the rotor shaft journal and bearing wear.
     (2) during assembly to ensure the tightness of the filter
     Requirements seal between the rotor and the rotor body intact, fastening nut tightening torque consistent with the provisions for ensuring a good seal between the two; fit the rotor body and the gap between the rotor shaft to the right to ensure that the rotor body, the lower end good seal. If the sealing is not more than 3, the oil will flow out from these parts will result in lowering the rotation speed of the rotor, centrifugal filtration effect weakened. Seal between the filter pan and cover to be intact, fastening nut tightening torque should meet the requirements to ensure that shell, a good seal between the cap to bearing no.f82225 prevent the oil from flowing out here, increasing oil consumption.
     (3) To carry out performance checks after installed
     Rotor body mounted on the rear rotor shaft, to check the situation of the rotor assembly, requiring flexible rotation, axial gap is not too large, and to meet the requirements; should be assembled after the filters installed in the engine operation performance check no leakage ; when the engine is running at medium speed 1-2min flameout, touch or the nearest ears in the 2-3min should be able to continue to feel the sound operation of the rotor inertia maintained.
