有的时候常发现买回的燃油内掺有水,有时也发现贮存燃油的桶底有水。若把混有水的燃油放进柴油机内使用,其害处有三:一是燃油内有水会造成油内浮游性添加剂、抗氧化剂等的分解或沉淀,使其失效腐蚀机件;二是水混入燃油内会使燃油氧化速度加快,其胶质生成量要大2.5倍;三是会产生微生物,经对储存14个月后的柴油进行测试,发现澄清出来的每ml水中有6200万个细菌,对油品和柴油机都有不良影响。 防止燃油有水的主要方法有: Sometimes it is often found that the fuel bought back contains water, and sometimes it is found that there is water in the bottom of the tank where the fuel is stored. If the mixed fuel into the diesel engine, its harmful effects are three: First, there is water in the fuel will cause the floating oil additives, antioxidants, such as decomposition or precipitation, so that failure of corrosion parts; the second is mixed with water The fuel will accelerate the oxidation rate of fuel, the glial generated 2.5 times larger; Third, will produce microorganisms, after 14 months of storage of diesel for testing and found that there are 62 million clarified bacteria per ml of water, Both oil and diesel have a negative impact. The main methods of preventing fuel from water are:
