AI Technical Summary

Technical Problem

Traditional mechanical equipment lifecycle management relies on equipment file registration and manual data entry, lacking the ability to continuously monitor and comprehensively analyze vibration changes and fault development during equipment operation. This makes it difficult to identify potential equipment degradation processes in advance, and maintenance arrangements lack a basis, which can easily lead to abnormal operation or delayed maintenance intervention.

Method used

By collecting vibration voltage signals during the operation of mechanical equipment, and combining the running time and fault duration, a set of equipment operation data is generated, life cycle segments are divided, fault density and vibration changes are analyzed, performance degradation segments are identified, and the equipment operating load and speed are adjusted. The running time of the degradation stage is recorded to achieve continuous life cycle management.

Benefits of technology

It enables the identification and traceability of changes in equipment operating status, provides a clear basis for equipment maintenance and early warning, dynamically adjusts operating load and speed, and avoids abnormal equipment operation and delayed maintenance intervention.
