Commercial Vehicle Filter Assembly

In order to make the lubrication system oil flow unimpeded, avoid impurities scratch, hair parts surface, oil before sending to the friction surface, must be strictly filtered. In order to achieve satisfactory filtering effect without increasing oil resistance, the coarse filter is generally connected in series with the main oil channel, and the fine filter is connected in parallel with the main oil channel.
1. Float type oil filter, in order to make the oil pump work well, the large particles and impurities in the lubricating oil must be removed before entering the oil pump. This task is undertaken by the filter. It is connected to the oil inlet of the oil pump. When the oil pump works, the oil is sucked from the narrow gap between the cover and the float. After filtering through the filter screen to remove the coarse impurities, the oil pipe welded on the float enters the oil pump. When the filter is silted up, the suction of the inlet pipe increases, overcoming the strong force of the filter and making the bad mouth leave the cover, the oil will enter the suction pipe directly from the ring without the filter.
2. The coarse filter is connected in series between the oil pump and the main oil channel, so it is also called the full flow filter to remove the larger impurities in the oil. It is mainly composed of upper cover, shell, paper filter element and bypass valve. When the engine is working, the lubricating oil with pressure is sent into the cavity around the filter core. The larger impurities in the oil are blocked by the paper filter core, and the clean lubricating oil enters the inner cavity of the filter core, and then enters the main oil channel of the cylinder block through the oil outlet.
3. Fine filter: its function is to filter out smaller impurities in lubricating oil, usually in parallel with the main oil channel, there are two kinds of centrifugal and paper plate.
4, the structure of centrifugal fine filter: the hollow shaft is fixed on the shell, the rotor body and the end sleeve are connected into one, located on the thrust bearing, can rotate freely around the rotor shaft. The rotor cover is fastened to the rotor body by a pinch nut, which is pressed with a spring to limit the axial movement of the rotor. Two opposing nozzles are installed below the rotor. When the engine is running, a small part of the oil is pumped out from the oil pump and enters the filter through the oil port. When the oil pressure is lower than 9s kpa, the intake pressure limiting valve closes and the fine filter does not work. When the oil pressure exceeds 98 kpa, the pressure limiting valve gradually opens, the oil through the central hole of the rotor shaft, from the oil outlet hole. Then through the oil hole into the rotor, and from the two nozzles ejected, then the jet reaction force is to push the hand rotation. When the oil pressure rises to 294 kpa, the rotor speed can reach more than 5000r/min, 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, is thrown to the rotor wall, and attached to the wall cover. The center of the clean lubricating oil, from the center into the two nozzles, constantly to the outside of the jet, the jet of lubricating oil flow back to the lower crankcase. [1]
