The definition of Maintenance is a combination of action carried out to restore in any equipment, to its normal working condition. There are two set of maintenance which is –Proactive and Reactive Maintenance. (1.)-On the one hand is –the Predictive Maintenance and Preventive Maintenance which are the proactive maintenance (2.) Then the Corrective Maintenance is a reactive Maintenance.
Therefore, the four Maintenance strategies are;-
(1) Preventive Maintenance – The type of Maintenance carried out regularly before any major break down to restore any equipment back to its normal working condition. It is the type of maintenance that is regularly performed on a piece of equipment or machine to lessen the likelihood of it failing.
Service is an act of repairing, replacing or correcting faulty part of a vehicle or machine. Servicing is all about vehicle and machine and when you are to service your vehicle or a machine you need to check first that, the problem of the vehicle or machine is known. After all has been observed and noted, changes commences which may include change of engine oil, replacement of brake pad, oil filter, fuel filter, brake lining and other parts checked. Therefore, Preventive maintenance improves the overall performance and safety.
Also vehicle servicing is done periodically but never the less, daily checking or inspection is necessary.
(2.) Predictive Maintenance-carried out before it is actually necessary after a careful examination or inspection of any equipment.-(through diagnostic method). This may be expensive, but it is worth checking out.
(3) Corrective Maintenance- the type of maintenance carried out after the break down of any equipment called -rectro-active strategy system of maintenance. is applied to situations where an obvious break, failure, or flaw has occurred. These maintenance concerns can be easily identified from the outset. Breaks failures for instance, may arise as a result of insufficient preventative maintenance just like other components.
(4) Reliability-Centre-Maintenance –the type of maintenance that involved the improvement programme in the cost –effective and technically feasible approach. It also comes to utilize a systematic structured approach based on the consequences of any failure.
THE FOUR (4)-LIKELY CONSEQUENCES OF POOR MAINTENANCE.
(1) –Reduced production Capacity.-This is when the Assets tend to perform under-expected target of which the consequence is down-time.
(2.)- Increase Production cost- This is when the real cost and opportunity cost increases due to asset not performing in its optimal level.
(3)- Low quality Product & services- This is when we have customer dissatisfaction that could result to lost of sales and costumers in the process.
(4)- Safety Hazard- that implies failure leading to injuries and finance and even lost of life in the process.
SOME WAYS TO OVERCOME THESE PROBLEMS
These problems can be partially overcome through Schedule inspections and monitoring programmes to assist in optimizing the planned maintenance intervals.
Through a structure like method called –Checklist- which is consistent with information about the actual condition of the equipment known.
A designed out maintenance method to eliminate high cost due to poor engineering design and maintenance practices or operation of a system outside its design-specification.
