The pore size of the filter is different, and the material selectively filtered is different.
The diesel filter mainly filters suspended matter and particulate matter. Since the viscosity of diesel oil is small and the fluidity is good, the filtration pore size is small. The oil filter mainly filters the colloidal substance in the working oil and filters the debris generated by the mechanical wear. Because the viscosity of the oil is large, the diameter of the filter core is also large.
In addition, high-quality filter cartridges have a “select filter” function that selectively filters impurities in the fluid as needed to filter the specifics of the impurities. Therefore, be careful in the filter products.
The role of the oil filter
The oil filter is a device that protects the engine, including two types of strainer and fine filter. The oil filter can remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil, and has strong filtering ability and small flow resistance, but the filtration efficiency is low.
Under normal circumstances, the various components in the engine are lubricated by the oil to achieve normal operation, but the metal debris generated during the operation of the components, the incoming dust, the carbon deposits oxidized at high temperatures, and some of the water vapor will continue to mix. In the oil, the service life of the oil will be reduced for a long time, and in severe cases, it may affect the normal operation of the engine.
Therefore, the role of the oil filter at this time is reflected. Simply put, the role of the oil filter is mainly to filter most of the impurities in the oil, to keep the standby oil clean and prolong its normal service life. In addition, the oil filter should also have the characteristics of strong filtration capacity, low flow resistance and long service life.
The role of diesel filter
Fuel filter has three types: Diesel filter, Fuel filter, and Gas filter. Its function is to filter out harmful particles and moisture in the fuel gas system to protect the diesel engine from uninterrupted work, etc., to reduce wear and avoid clogging.
Generally, there are various impurities in the gasoline, and the fuel tank will precipitate a certain amount of dirt for a long time, and the above reasons will affect the quality of the gasoline. The function of the filter is to filter the above impurities, and the gasoline in the fuel tank is filtered by the gasoline grid to reach the engine, and the cleaning purity can be effectively guaranteed.
