Oil filter is a very important part. It is very effective in both automotive and mechanical equipment. It can effectively filter impurities in oil, make gasoline more pure, and also make mechanical equipment. For better work, let the filter manufacturers talk about the problems often encountered in the use of oil filters today.
First, the oil filter bottom perforation problem
Perforation at the bottom of the oil filter, except for a few because the steel plate has blisters, the more reason is the material of the outer shell steel. Whether the bottom is easy to perforate has some relationship with the thickness of the outer casing, but it is not the main reason. When the steel material is not good, the bottom of the oil filter is easily corroded and perforated due to water, impurities, etc., just like a person with poor resistance, and a little cold will catch a cold. The material of the steel is the key. The bottom of the oil filter with good quality occasionally pierces, but the probability of perforation is extremely low.
Second, the seal leaks oil
1. The problem of the material of the sealing ring, the temperature resistance of the sealing ring is not good, the oil filter will shrink after a period of use, resulting in oil leakage or oil leakage of the sealing ring.
2. The verticality of the threaded plate is not good (not the standard 90 degree vertical), resulting in uneven sealing around the circumference (the inclination error of the left and right sides is 0.3 mm, which is more than unqualified). At the beginning of installation, due to the elasticity of the sealing ring The calibration will not leak oil. After a period of use, there will be some shrinkage. The side with large error will shrink due to heat shrinkage of the seal ring, the elasticity of the seal ring will be reduced, and the sealing performance will be greatly reduced.
The use of oil filters is for better service of mechanical equipment, paint is also used in cars, and regular maintenance and cleaning work is required for oil filters.
