The structure of the diesel oil filter is roughly the same as that of the oil filter, there are two types of interchangeable type and rotary type. However, its operating pressure and oil temperature resistance requirements are much lower than the oil filter, and its filtration efficiency requirements are much higher than the oil filter. The filter element of diesel oil filter mostly USES filter paper, also has used felt or high polymer material. In addition to filtering mechanical impurities in diesel oil, another important function of diesel oil filter is to filter water. The existence of water is very harmful to the oil supply system of diesel engine, and the corrosion, wear and damage of cylinder piston ring can even cause cylinder pulling phenomenon, which can also worsen the combustion process of diesel oil. The diesel oil filtration system can separate the water according to the different liquid density through the fluid flow control technology to achieve the effect of water filtration.
