It is only in recent years that manufacturers have begun to reveal the financial benefits rather than merely report on the engineering improvements to their plant, created by utilizing effective Condition Monitoring techniques. These techniques can can give advanced warning of mechanical or structural problems on plant equipment that can then be rectified at a convenient time. Many companies choose to use breakdown maintenance as their main maintenance activity with the subsequent penalty of high maintenance cost, lost production and considerable spare parts holding. Failure of a single bearing or coupling can produce catastrophic results. These facts, atogether with increasing costs for new equipment, have placed increased demands on companies to keep existing equipment operating efficiently and reliably. Outmoded “breakdown” maintenance programmes and programmes of periodic inspection and overhaul are being replaced or supplemented by predictive maintenance techniques which allow onstream detection of developing problems. Monitoring of bearing temperature, ultrasonic testing, lubrication analysis, vibration monitoring and many other techniques are being used to combat failures and unscheduled downtime. Therefore, operating an effective Predictive Maintenance programme built around an organised schedule of periodic checks to monitor changing plant conditions will improve the profitability of an organisation.
