YYF-1型油液质量快速分析仪(见本刊1992年第10期45页)在使用中有一个油液报废指标的标定问题。为了说明这个问题,有必要了解油质劣化综合指标的含义。润滑油在机械运转过程中会逐渐变质,造成变质的主要是非溶解性杂质,酸值,铁含量,粘度,水分等。用分析仪检测时,若水分超标,仪表指针不断向右漂移,且不能稳定下来;含 YYF-1-type oil rapid mass analyzer (see journal publication No. 10, 1992, page 45) in the use of a standard oily waste calibration problem. To illustrate this issue, it is necessary to understand the meaning of the composite indicator of the deterioration of oil quality. Lubricants in the process of mechanical operation will gradually deteriorate, resulting in deterioration of the main non-soluble impurities, acid value, iron content, viscosity, moisture and so on. With the analyzer test, if the water exceeds the standard, the meter pointer constantly drifts to the right, and can not be stabilized; with
