  国内外对滤油机的脱水效率的提高提出了很多改进措施和方法,马红麟提出三级变压器油真空滤油机的处理效率和处理效果是最好的。郭蕾等提出了采用高效、高精度过滤技术及独特的真空分离技术:采用了密集式喷嘴和特制网眼板相结合的脱气、脱水结构,提高了油液在真空分离室中的脱气、脱水效率。根据前期研究成果表明,从温度、真空度、初始含水率、油膜蒸发表面积、蒸发表面的更新、蒸发持续时间等几个因素来提高滤油机的油水分离效率,效果不太显著。刘阁等通过在滤油机中部通入一定速率的干燥空气,使其在油水混合液中大量的细微“气泡”,由于“气泡”的压力远高于水的饱和蒸汽压和气体在油中的分离压,从而使油中“气泡”不断上升和扩大,使油水表面积不断得到增大和更新,从而提高了油水分离效果。

  为了从理论上对滤油机中部通入气体的油水分离效率进行深入研究,作者考虑了滤油机工作过程中油水汽气四相流、水滴蒸发相变等因素,对滤油机的油水分离流场的数学物理模型以及水滴运动蒸发的相变方程进行建立;进一步分析不同气体速率对油水分离过程中的油水汽气四相体积分数分布以及轴向脱水率的影响规律,进而获取气体速率对油水分离动态特性的影响规律,揭示滤油机油水在一定真空条件那个棋牌信誉好下的油、水、蒸汽、气体的四相流体动力学特征,真空技术网(http://tai3456.com/)认为这为研究滤油机的除水效率提供前期基础。
