分析式铁谱仪的结构

The structure of an analytical ferrospectrometer

分析式铁谱仪是一种常用的铁谱仪器，它是将油液中的磨损金属微粒及污染杂质颗粒从油液中分离出来，制成铁谱基片，再在铁谱显微镜下进行定性观测和定量分析。

Analytical ferrography is a commonly used ferrography instrument. It separates the wear metal particles and contaminant particles from the oil and makes ferrography base, and then carries out qualitative observation and quantitative analysis under the ferromagnetic microscope.

从设备润滑系统或液压系统取的原始油样经制备后，由微量泵输送到与磁场装置2呈一定角度的玻璃基片1上。在随油样流下的过程中，可磁化的磨损微粒在高梯度磁场作用下，由大到小依序沉积在玻璃基片的不同位置上，沿磁力线方向 （与油流方向垂直）排列成链状，有色金属磨损微粒及污染杂质 颗粒主要靠重力作用，随机沉积在铁谱基片上，经清洗残油和固定微粒的处理之后，制成铁谱基片。

The original oil samples obtained from the equipment lubrication system or the hydraulic system are prepared by the micropump to the glass substrate 1, which is in a certain angle to the magnetic field 2. In the process of oil flow with the magnetizable, wear particles in high gradient magnetic field, in order from large to small deposition at different positions on the glass substrate, along the magnetic field direction (vertical direction and oil flow) are arranged in a chain of non-ferrous metal wear particles and pollution of impurity particles mainly by gravity random, deposition spectra in the iron substrate, after cleaning the residual oil and fixed particle processing, made of iron substrate spectrum.

在铁谱显微镜下，对铁谱基片上沉积的磨损微粒进行大小、形态、成分、数量等方面的特征定性和定量分析后，就可以对所监测的设备的零件的摩擦学状 态作出判断。

Based on Ferrography, qualitative and quantitative analysis of the size, morphology, composition and quantity of worn particles on Ferrography substrate can make a judgement of the tribological state of the parts monitored.
