摘要
油液污染度检测技术应用于具有封闭或半封闭式润滑系统液压设备中液压油、润滑油及合成油的检测,可以检测多种油液的固体颗粒污染程度。当前技术较为领先的污染度检测仪器大多采用遮光原理研制,在光源的选择上主要采用LD激光二极管。提出一种应用LED发光二极管光源的油液污染度在线检测颗粒计数器设计方案,以检测液压油的污染状况,并对LED和LD光源进行比较分析。
Oil contamination detection technology is applied to a closed or semi-closed lubrication system of the hydraulic equipment to detect hydraulic oil,lubricating oil and synthetic oil,which a variety of fluid solid particles pollution can be detected.Contamination testing instrument of current technology is the leading most of the shading principle,on the choice of light source mainly adopts LD laser diode.The design scheme of oil contamination on-line detecting particle counter is an application of LED light-emitting diode light source,to detect the pollution of hydraulic oil,and the LED and LD light source for comparative analysis.
