Condition monitoring is a process to monitor the health of machinery or equipment. Vibration condition monitoring aims to detect and identify early signs of malfunction through surveillance and testing. Close monitoring and understanding of vibration levels can provide valuable clues as to how a machine is wearing or deteriorating, allowing for pre-emptive maintenance to reduce the risk of potentially costly down-time or even catastrophic failure.
Often operating performance can change subtly over time. Long term condition monitoring can highlight when change takes place allowing action to be taken to remedy. It can also be used to identify high load cases or extreme events which might otherwise go un-noticed. Monitoring these behaviours and resolving them when they occur can greatly improve efficiency of day to day operation as well as avoiding costly halts in production.
Xi’s specialist measurement team can also support condition monitoring work where unusual or unexpected results are found. Using techniques such as; Optical Deflection Shape Analysis (ODS), finite element (FE) simulations, shaft orbital analysis, Xi can delve deeply into problems allowing for quick and efficient fault resolution.
Typical issues may include:
- Shaft alignment
- Structural Resonance
- Axial and torsional resonance
- Damaged or loose structural fittings
