液压油抗乳化首检不合格原因探讨

Discussion on Unqualified Causes of First Inspection of Hydraulic Oil' s Demulsibility

抗乳化性能是衡量液压油质量优劣的一项重要指标。在液压油生产过程中,影响其抗乳化性能的因素有多种。分别从生产工艺、包装和设备等方面进行统计分析,通过分析发现,工艺设计、管线残留、包装物污染、阀门渗漏对液压油首件检验抗乳化性能有一定影响,通过工艺改进、控制最小调合量、顶线量、包装物验收和阀门质量,可以大幅度提高液压油首件检验抗乳化合格率,即保证了产品质量,具有一定的经济效益。

The demulsibility is an important quality index of hydraulic oil. in the industrial production, there are a variety of factors influencing the demulsibility. It is found that the first inspection result of hydraulic oil＇s demulsibility would be certain-ly affected by the process design, piping residue, packaging pollution and valve leakage base on the statistical analysis on the data from production process, packaging and equipments etc. The qualified ratio of first inspection of hydraulic oil＇s de-mulsibility, which is to ensure the production quality and certain economic benefits, can be greatly improved by the promo-ting process, controlling the minimum amount of blending, cap - line amount, packaging check and the quality of valve.
