摘　　要：考察了加油机用普通滤芯和防水滤芯对油品静电起电的影响。研究表明,滤芯能显著影响油品的静电起电特性。滤芯的孔径越小,油品所带的静电电荷量越大;相同情况下,汽油的静电危险性高于柴油;防水滤芯对油品静电起电的影响略大于普通滤芯。加油站应根据油品的特性合理选择滤芯,必要时应降低油品流速,以减小静电安全风险。The effect of the ordinary filter elements used in the refueling machine on the static electrification of oil is studied.The results show that filter elements can significantly affect the oil static electrification characteristics:the smaller the pore diameter of filter element is,the larger the charge amount of oil electrostatic is;under the same conditions,the electrostatic hazard of gasoline is higher than that of diesel;the effect of waterproof filter elements on the static electricity of the oil is slightly larger than that of the ordinary filter elements.Gas station should select filter elements according to the characteristics of oil,and when necessary,reduce the oil flow rate to reduce the electrostatic risk.
