Abstract
A computer system implements a process for gathering, synthesizing, and analyzing data relating to a pump and/or seal or other rotating equipment failure. Data indicating the current state of the equipment is gathered and verified prior to a failure occurring so that accurate information is available. After a failure or problem occurs, data about the problem or failure are methodically gathered to aid in the determination of the root cause of the failure. In particular, visual images of failure modes are provided to the user to ensure that proper and accurate data are obtained. A user also is directed to gather other data about the failure and the system. After data relating to the problem or failure has been gathered, the data are synthesized and an analysis is performed to determine the root cause of the failure or problem. These various methods and apparatus allow a non-specialist to properly identify and diagnose a failure or problem associated with a mechanical seal and pump. After the analysis has determined the root cause of the problem or failure in the system, the system suggests corrective actions and plans for implementing a corrective action. Installation instructions, training and safety information can be provided to the user to ensure proper execution of the selected corrective action. A plant reliability manager also may monitor the progress and verify that installation, maintenance and failure correction are performed correctly. The plant reliability manager also may track problems or failures by each individual or department to determine if additional training is needed.
