  2. 2. Vibration analysis for predictive maintenance of a rotary pump. : Optimal accelerometer configuration based on vibration analysis for cavitation detection of a bi-winged positive displacement pump.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Gustav Osswald; [2019]
    Keywords : ;

    Abstract : Predictive maintenance based on condition monitoring uses sensor and system data to prevent damage, in advance to a failure occurring, allowing for a service to be performed at an optimal position in time. Condition based predictive maintenance estimates time of system failure based on a priori information, which has shown to be much more cost effective than traditional maintenance methods. READ MORE
