Bearing Wear Monitoring - The Bently Approach
The an ideal scenario, machines with Rolling Element Bearings would be monitored in the same way as critical journal bearing machines (vibration transducers at each bearing, bearing temperature, Keyphasor† sensor, online monitor). However, it can be economically difficult to justify that level of monitoring. The best method for monitoring bearing temperature, wear and overall condition is throughonline monitoring- using either a permanently installed, continuous or scanning systems. With an online system, a propertransducer suiteis needed to detect when a machine is having a problem.
在没有在线监控系统的情况下portable data collector(PDC)是下一个最好的方法。的一个重要组成部分tablishing a PDC route is defining how often the data is taken. The more often the data is collected, the more likely an early bearing failure detection will be made. But as a consequence, the cost of the condition monitoring will be higher due to more frequent data collection and analysis. The route creation and timing depend on the machine operating hours, running speed, load, process and environmental conditions, and so on.
