随着液压技术愈来愈向高压、高精度、小型、集成化发展,油液的不洁度和污染对系统造成的危害愈来愈受到人们的重视,因而对油液的高精度过滤和污染控制提出了更高的要求。同时,也发展了许多种类的机械式精密过滤装置。但是,随着精度等级的提高、滤油阻力的增加,在过滤装置上的能源消耗也随之增加,且更容易引起滤眼(孔)堵塞,影响正常工作。为了克服这些缺点,需要开发新的净油技术。根据研究,利用静电技术对绝缘性油液的净化在提高滤油精度、节约能源、延长油液使用寿命等方面都显示出其有突出的优点。国外自1976年开始已研制出一批新型的静电净油机,并得到了
With the hydraulic technology is more and more to high-pressure, high precision, small, integrated development, the oil impurities and pollution hazards to the system more and more people’s attention, and thus the high-precision filtration and pollution of the oil Control raised higher requirements. At the same time, many kinds of mechanical precision filtration devices have also been developed. However, with the improvement of the accuracy level, the increase of the oil filter resistance increases the energy consumption of the filter device, and more easily causes the clogging of the filter eye (hole) and affects the normal operation. In order to overcome these shortcomings, new clean oil technologies need to be developed. According to research, the use of electrostatic technology for insulating oil purification in improving the oil filter accuracy, save energy, extend the life of the oil, etc. have shown its outstanding advantages. Foreign countries since 1976 has developed a new batch of electrostatic oil purifier, and got
