离心泵 用预知的振动监测技术诊断离心泵的轴承故障、转子的不平衡、轴的不同轴度和其它故障是很有效的。但是,如果仅仅依赖预知维修技术,就无异于宣告他们不防止故障发展,而是在等待故障。 尽管实践已证明,定期更换润滑油可以显著地减少轴承损坏,但并没有多少化工厂按照图1推荐的换油周期及时更换润滑油。 Centrifugal Pumps Predictive vibration monitoring techniques to diagnose centrifugal pump bearing failures, rotor imbalances, shaft misalignments, and other malfunctions are effective. However, relying solely on predictive maintenance techniques is tantamount to announcing that they do not prevent failure, but are waiting for failure. Although practice has shown that regular replacement of lubricants can significantly reduce bearing damage, but not how many chemical plants in accordance with the recommended oil change intervals in Figure 1 timely replacement of lubricants.
