使用中的润滑油含有金属磨损粒子的多少,不仅仅反映机件磨损的大小,而且还与润滑油的劣化有一定的关系。在各种金属磨粒中,铁粒子最有代表性。铁粒子最大的特点是具有可磁化的性质。利用这个性质研制出的磨损和润滑油品质劣化监测器,结构简单,反应灵敏。这种监测器可望在各种机器中使用。本文就监测器的工作原理、结构、试验和实际使用情况作一介绍。 The use of lubricants containing metal wear particles much, not only reflects the size of mechanical wear, but also with the deterioration of lubricants have a certain relationship. Among various kinds of metal abrasive grains, iron grains are the most representative. The biggest feature of iron particles is the magnetizable nature. The use of this nature developed wear and lubricant deterioration detector, the structure is simple and responsive. This monitor is expected to be used in a variety of machines. This article describes the working principle of the monitor, structure, test and actual use of an introduction.
