提出一种基于介电常数法的润滑油水分快速分析方法。该方法通过测定含水润滑油及添加无水CuSO4脱水剂后介电常数的差值,通过实验得到介电常数法差值和润滑油水分含量的关系式得到润滑油中水分的含量。运用此方法可以快速估计润滑油中水分的含量,并作为失效判断的一项基本依据。
A rapid method for analyzing the moisture of lubricating oil based on dielectric constant method is proposed. The method determines the water content in the lubricating oil by measuring the difference of the dielectric constant between the water-containing lubricating oil and the anhydrous CuSO4 dehydrating agent, and obtaining the relation between the difference of the dielectric constant and the moisture content of the lubricating oil by experiments. Use this method can quickly estimate the content of water in lubricating oil, and as a basic basis for failure judgment.
