By looking at the type, size and shape of the metal particulates that are suspended in the oil, the health of the equipment it is lubricating can also be determined.
Condition-based maintenance can be applied to mission critical and non-mission critical assets. Condition-based maintenance CBM Definition Condition-based maintenance CBM is a maintenance strategy that monitors the actual condition of the asset to decide what maintenance needs to be done.
As they degrade, or fall out of alignment, the amount of vibration increases. Empower your maintenance team Leverage the cloud to work together, better in the new connected age of maintenance and asset management.
Spot readings can be performed at regular intervals using portable instruments Sensors can be retrofitted to equipment or installed during manufacture for continuous data collection Critical systems that require considerable upfront capital investment, or that could affect the quality of the product that is produced, need up to the minute data collection.
Data collection Data can be collected from the system by two different methods: Compared with preventive maintenancethis increases the time between maintenance repairs, because maintenance is done on an as-needed basis.
CBM introduces new techniques to do maintenance, which can be difficult to implement due to resistance within an organization. More expensive systems have built in intelligence to self-monitor in real time.
Checking a machine for these indicators may include non-invasive measurements, visual inspection, performance data and scheduled tests. In particular, CBM is highly effective where safety and reliability is the paramount concern such as the aircraft industry, semiconductor manufacturing, nuclear, oil and gas, et cetera.
In the example of industrial equipment, oil analysis can perform an additional function too. CBM dictates that maintenance should only be performed when certain indicators show signs of decreasing performance or upcoming failure. Today, improvements in technology are making it easier to gather, store and analyze data for CBM.
For example, sensors throughout an aircraft monitor numerous systems while inflight and on the ground to help identify issues before they become life threatening. Typically, CBM is not used for non-critical systems and spot readings suffice. Condition data can then be gathered at certain intervals, or continuously as is done when a machine has internal sensors.
With CBM in place, it still requires competence to turn performance information from a system into actionable proactive maintenance items. Vibration sensors can be used to detect when this becomes excessive.
Asset conditions need to trigger maintenance within a long enough time period before failure, so work can be finished before the asset fails or performance falls below the optimal level.
Older equipment can be difficult to retrofit with sensors and monitoring equipment, or can be difficult to access during production to spot measure.In this thesis, a novel data-driven framework to condition monitoring of gearbox is studied and illustrated using simulated and experimental vibration signals.
This involves. Wind Turbine Generator Condition Monitoring via the Generator Control Loop Mahmoud Nouh Zaggout A thesis presented for the degree of Doctor of Philosophy.
condition based maintenance, parameter selection for monitoring condition, evaluation of condition monitoring results are issues influencing the effectiveness of condition based maintenance. All these selections of components and parameters to be monitored, monitoring.
Condition monitoring is a process of continuously monitoring operational characteristics of a machine to predict the need for maintenance before a deterioration or breakdown occurs.
Condition Based Maintenance (CBM) differs from earlier used method of preventive maintenance by centering the maintenance based on the actual condition of the. procedure of condition monitoring is suggested in this thesis. Even though optimizing periodic maintenance using condition monitoring techniques leads to many benefits, there will be initial costs that may discourage the.
