The maintenance methods have special importance in the industry.
Here are 5 important maintenance methods are being applied in the Industry
Maintenance Recovery
This method is also known as repairing, or "maintenance Fire" (fire-fighting maintenance), maintenance based on failure (failure or breakdown maintenance based maintenance). In this way, the maintenance is performed only when the damage occurred. It is considered as a feasible approach, where repair damage that is common in small production facilities, at divers ...
However, like Fire, this type of maintenance is often accompanied by serious damage to the equipment, affect the production schedule. Moreover, with the expansion of production scale, competition has forced managers to apply other methods efficient and more reliable.
Preventive Maintenance
This method is based on the reliability of the device components. The data can be used to analyze how the damage of machine components and allow maintenance engineers to define a regular maintenance program for it. Preventive Maintenance trying to identify a series of checks, replace or modify parts of the machine with a frequency based on the frequency done damage. In other words, preventative maintenance to maintain the effect of overcoming the problems related to the abrasion of machine components. Therefore, after the test, not always necessary to replace the component.
To maintain prevention activities, a support system is necessary decision and it is often difficult to determine the period of time between the most efficient maintenance due to lack of historical data. In many cases the maintenance methods are used, most of the machines are maintained useful lifespan significantly. However, this approach often leads to unnecessary maintenance, even damaging the machine if not properly maintained.
Maintenance Opportunities
Is performed at the same time to replace or check the different components on the same machine or plant. Maintenance can type the entire plant must be shut down at the scheduled time to perform the relevant tasks simultaneously. Maintenance opportunities often conducted in a way to save expenses when at least two maintenance work to be carried out simultaneously. To reduce overall maintenance costs and stop production. This maintenance method requires the cooperation and support of the production department dispatch.
Maintenance based on condition
Maintenance decisions are made depending on the measured data from a sensor system. Today, some monitoring techniques such as vibration monitoring, analysis and test lubricants ultrasound ... The parameters of device data can be monitored for engineers to know the machine status, allowing maintenance personnel perform necessary maintenance before the failure occurs. This method is usually applied to the camera and machine translation, eg turbines, centrifugal pumps and compressors ... However, the limited quality data collection and reduce efficiency and the accuracy of the method of maintenance based on status.
Predictive maintenance
Unlike maintenance policy based on status, maintenance predict the data collected, important parameters to be controlled for analysis to find out a possible tendency to change. This makes it possible to predict when the control value reaches or exceeds the safety threshold value. The maintenance staff will then be able to plan when (depending on operating conditions), the number of parts to be replaced or repaired.
