Oil filter, just as its name implies is used to remove impurities from the oil, a lot of need to use oil of mechanical equipment are used to the oil filter
, air filter
manufacturer today mainly oil filter used in auto oil filter to you talk about often can see the problem: a problem at the bottom of the oil filter, oil filter at the bottom of the perforation perforation, except a few because of the steel plate have sand holes, more reason is shell steel material.
Bottom is easy to punch, have some relationship with the shell thickness, but it is not the main reason.
Steel material is bad, because at the bottom of the water, impurities such as precipitation, it is easy to cause the oil at the bottom of the filter by corrosion perforation, like a person resistance is poor, a little bit by cold catches a cold.
Steel material is the key, the oil filter with good quality at the bottom of the perforation, occasionally but perforation probability is very low.
Second, the seal oil 1.
Seal material problem, poor seal temperature resistance, oil filter will shrink after a period of time, resulting in seal oil leakage or spill.
Die verticality bad mouth (
Is not a standard of 90 degrees to the vertical)
And results in uneven around the seal (
Left and right side tilt error limit is zero.
3 mm, more than for the unqualified)
, just start the installation, due to the elastic correction by the sealing ring will not leak, use after a period of time there will be some shrinkage, because the seal on the other side of the great error in the thermal contraction, sealing ring elasticity decreased, sealed performance is greatly reduced, would have started to leak.
Three, sealing side break the spill if use normal steel sealing plate, usually rarely appear this problem.
Appear rupture sealing package edge, common electroplating sealing plate, because after the seal plate electroplating electroplating looks the same, but, before plating is likely to be adopted all kinds of steel, some steel is brittle, when bending pressure does not burst, but by a machine while using vibration, without a long burst.
Generally the use of the oil filter time is not fixed, are influenced by many factors, such as how much gas impurities in diesel oil, if too many impurities, to achieve the best adsorption capacity of oil filter, oil filter of life has an end, so in order to prolong the service life of oil filter, consumers need to do a good job of cleaning and maintenance of oil filter.
