Oil filter in the lubricating system in order to make the lubricating oil flow unimpeded, avoid the surface of impurities scratches, brushed parts, oil before sent to the friction surface, must be strictly filtered. In order to achieve satisfactory filtration effect without increasing oil resistance, the coarse filter is usually 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 collection filter, in order to make the oil pump work well, must remove the large impurities in the lubricating oil before entering the oil pump, this task is undertaken by the collection filter. It is connected to the oil inlet of the oil pump. When the oil pump works, the oil is sucked through the narrow slit between the cover and the float. After filtering the thick impurities through the filter, the oil pipe welded on the float enters the oil pump. When the filter screen is silted up, the suction force of the oil inlet pipe increases, which overcomes the strong filter screen and causes the bad hole to leave the cover.
