Background
The lubrication system is a generic term for a series of oil supply and discharge devices for supplying lubricant to a lubricated member, and accessories thereof. The lubricating system is necessary to ensure the reliable work of the steam turbine and other rotating mechanisms and prolong the service life of the steam turbine and other rotating mechanisms. If the lubrication system fails, the corresponding rotating machine can be seriously abraded and heated, and the rotating machine can be seriously damaged or destroyed. Therefore, the health management of the lubrication system plays an important role in the management of the ship. The types of failures of lubrication systems are various and can be roughly classified into two types: one is functional failure, and the system deviates from normal functions due to abnormal working conditions, such as damaged parts, improper operation and the like, and the failure can normally operate by correcting parameters or replacing corresponding parts; the other is acoustic failure, the lubrication system operates under normal conditions, but vibration noise is large. Acoustic faults are potential indicators of equipment functional faults, and such faults are related to parameters such as equipment operating conditions, pipeline characteristics, equipment processing techniques, and equipment functional characteristics.
