Resistance to fuel is a synthetic organic lipid liquid, different from the ordinary mineral oil, transformer oil of turbine, over the years, the domestic various coal-fired power plant of fuel use, degradation of oil is more serious, cause the system jamming, jumping machine downtime, frequently occurred.
　　Because of the fuel oil heat stability and hydrolysis stability is quite poor, cannot use of mineral oil regeneration purging method. For example, it cant use white earth pickling process, or you will hydrolysis generation corrosive phosphate; It with many of the filter material surface and sealing material are not compatible, it will make a lot of dissolved effect sealing material, metal was dissolved; Density particularly big, not only greater than turbine oil, and greater than water; It has a solvent effects, easy to form will sink thing, jams mesh...... . Therefore, resistance to fuel must use special purification equipment.
　　I company of production of fuel filter all filter part for 304 stainless steel, through the diatomite, 3 oxidation 2 aluminium, molecular sieve on oil regeneration, filter and purify, can achieve and over part of the imported products, also can use the United States imported regeneration filter.
