分析式铁谱仪 将从润滑系统中取得的分析油样经稀释处理后取样到玻璃管中，经微量泵将分析油样输送到安放在磁场装置上方的玻璃基片的上端，玻璃基片的安装与水平面成一定的倾斜角，以便沿油流方向形成一逐步增强的高强度磁场，同时又便于油液沿倾斜的基片向下流动，从玻璃基片下端经导流管排入废油杯中。分析油样中的可磁化金属磨粒在流经高梯度强磁场时，在高梯度磁力、液体粘性阻力和重力联合作用下，按磨粒尺寸大小有序地沉积在玻璃基片上，并沿垂直于油样流动方向形成链状排列。在分析油样从基片上流过之后，经用溶液洗涤基片，清除残余油液，使磨粒固定在片上便制成了可供观察和检测的铁谱片。

Ferrography analysis will be obtained from the analysis of the lubrication system oil sample was diluted after sampling into the glass tube, by micro pump will be transported to the upper end of the oil sample analysis is placed in a glass substrate above the magnetic device, installation and level of glass substrate surface with a certain tilt angle, so that the oil flow the direction of the formation of high intensity magnetic field gradually increased, at the same time for the oil flows down along the inclined substrate, glass substrate from the lower end of the guide tube into the oil cup. Analysis of oil sample magnetizable metal debris flows in high gradient strong magnetic field, the combined effect of high gradient magnetic liquid, viscous drag and gravity, particle size by grinding orderly deposited on glass substrates, and form chains along the perpendicular to the flow direction of the oil sample. After analyzing the flow of oil from the substrate, the residual oil was removed by washing the substrate with solution, and the abrasive particles were fixed on the chip.
