Oil filter is a very important part in the engine lubrication system. In the high speed operation of the engine, it is inevitable to produce its tiny particles, and the long run will lead to a constant decline in the performance of the oil. In order to ensure the performance and service life of the engine, the quality of the oil filter is the basic guarantee.
Quality of the oil filter of oil bottom shell oil magazine filter to clean the oil supply of the crankshaft, a connecting rod, a cam shaft, turbocharger, piston ring, such as movement vice, to lubrication, cooling, cleaning effect and to prolong the life of these parts.
Common problems of poor quality oil filter:
1, the use of inferior oil filter paper
Most of the cotton producing inferior filter paper (even with rags and rags), can not guarantee the stiffness of the filter paper and water resistance.
High quality filter paper made of pure wood pulp and phenolic resin manufacturing, after 180 degrees bake oven. Filter filter paper of the filter filter is fully solidified, stable performance.
2, paper core glue is not full
The use of low-quality filter paper, in order to ensure the oil is not blocked. Can only reduce the amount of glue injection, the amount of glue is not directly caused by the oil filter short circuit, through. The most serious consequence is that large particles have not been filtered out, causing damage to the engine directly into the system.
3, bypass valve spring soft
As a result of the use of inferior filter paper, but also because of the poor quality of paper due to the blockage of the circuit may cause. Therefore, the use of a soft spring, the oil pressure increase in order to not filter the oil through (short circuit). The consequences of the above second points.
