酸值是航空发动机润滑系统的一项重要指示 ,根据酸值的大小可以判断使用中润滑油的变质程度 ,对航空发动机运转状况进行动态监测 ,以便人们更换油料 ,从而保证机器不会由于油的原因而发生故障、损坏。酸值的测定 ,一般采用酸碱滴定法 ,即指示剂法和电位法判断终点 [1～ 4]。指?
Acid value is an important indicator of aeroengine lubrication system, according to the size of acid value can determine the degree of deterioration of the use of lubricants, the dynamic state of the aero-engine monitoring, so that people change the oil, so as to ensure that the machine will not be due to the oil Reason for failure, damage. Acid value determination, the general use of acid-base titration method, that is, the indicator method and the potential method to determine the end point [1 ~ 4]. Refers to?
