船用低速柴油机轴承磨损监测系统工作原理的研究

The Research of Bearing Wear Monitoring System's Working Principle for Marine Low-speed Diesel Engine

随着船用低速柴油机轴承磨损监测系统的启用,真正实现了轴承磨损状态的实时监测和开验轴承次数的减少。介绍了船用低速柴油机轴承磨损监测系统的一般工作原理、功能与特点,对其关键技术,下止点位置传感器的信号处理,尤其是速度补偿技术进行了重点分析,为更好地用好该系统提供参考。

With the introduction of Bearing Wear Monitoring （BWM） on low speed marine diesel engines, real-time monitoring of bearing wear condition are realized, open-and-inspection are less nee- ded. BWM systems of low speed marine diesel engines are introduced from the aspects of working princi- ples, function and characteristics. Moreover, its key technology, the signal processing of BDC position sensor, especially the speed compensation techniques are analyzed in detail, which offers reference for good application of this system.
