1, meaning
machine filter located in the engine lubrication system. Upstream of the filter machine is the oil pump, is downstream from various parts of the engine that require lubrication. Machine filter in English: Oil Filter
2, the filter mechanism of action
machine filter The mechanism of action is to filter oil from the oil pan filter out harmful impurities, to clean oil supplied to the crank, connecting rods, camshafts, turbocharger, piston rings and other moving sub, for lubrication, cooling, cleaning effect, thereby extending the life of these parts.
3, the structure of the filter unit
machine filter according to the structure with a replaceable, spin-on, centrifugal; press disposed in the system can be divided into full-flow type, shunt type. Filter machine filter material used filter paper, felt, metal, nonwoven fabric and the like.
4, filter machine development
before the eighties, domestic engines are mostly interchangeable filter machines. Such a filter structure is to filter and other components, such as springs, seals, etc. into a metal housing, the housing and the like with a metal filter cartridge holder connector is fixed by a tie rod. Interchangeable filter unit advantage is the low cost, only regular maintenance to replace the filter; deficiencies in that excessive sealing point, missing equipment maintenance to replace the filter part may easily cause the vulnerability, and the replacement of trouble. Since the early eighties, spin-on filter selection gradually recognized as domestic OEMs. Characteristics of spin-on filter is provided with an internal check valve, bypass valve, only a seal point, the overall change, greatly improving the sealability and easy to replace, which filter material to filter imported, so high filtration efficiency , flow resistance, and long life.
5, an oil filter replacement method
In professional car repair station, the first car into a garage parking, a hoist to raise the vehicle height 160-170cm. Remove the oil filter is rotated counterclockwise with a dedicated oil filter wrench. Then removed from the box and a new oil filter and check the thread rubber seal on the new filter, a clean control mount on the cylinder block and then sealed with a small amount of lubricating oil filters coated rubber.
The third step is to install. The oil filter is mounted by hand, and then tighten the fixed oil filter with a special tool clockwise. After installation, the fill level height of the engine oil to a predetermined operation of the engine at least 3 minutes, and then check whether the oil leakage.
