| 液压系统在运行过程中磨损与腐蚀产生的剥落物混入油中，通过观察与测量油液中磨损粉末的形态、大小、颜色与数量等可判断出液压系统的磨损与腐蚀情况，铁谱技术便是常用的油液测试分析技术。 The hydraulic system of wear and corrosion in the operation process of wear powder mixed with oil, through observation and measurement of the oil in the shape, size, color and quantity can determine the abrasion and corrosion of hydraulic system, the ferrography is commonly used for testing oil analysis technology. 铁谱技术用以分离磨粒的装置如图6所示。通过微量泵将一定容量的油样抽入胶管中，然后沿着一倾斜的玻璃铁谱片流进贮油杯，油样中的磨粒在玻璃片下的磁铁作用下，磨粒滞留在铁谱片上，沿流动方向从大到小分布，不同大小磨粒沿磁场方向呈链状排列。 The device for ferrography is used to separate the abrasive particles as shown in Figure 6. The micro pump will be a certain capacity of the oil sample is pumped into the hose, and then along an inclined glass of Ferrography into the storage cup, the oil sample abrasive on glass substrate under the magnet under the action of abrasive particles trapped in the ferrography, along the flow direction from large to small distribution of abrasive particles of different sizes along the magnetic field direction and arranged in a chain. 现代分离和分析磨粒的仪器有直读式铁谱仪、分析式铁谱仪和在线式铁谱仪三种。 Modern instruments for separation and analysis of abrasive particles include three kinds of direct reading ferrography, analytical Ferrography and on-line ferrography. |
