Selection of Maintenance Strategy

The savings by reducing downtime through the implementation of CBM strategy can be considerable but for the whole strategy to work, there must be some means of knowing the condition of the equipment and getting a warning sign of problems sufficiently far in advance to arrange a schedule of shutdown, with the necessary skilled and intelligent maintenance staff and spare parts standing by. The main function of condition monitoring is to provide the knowledge of machine condition and of its failure rate, obtained through selection of a suitable parameter such as vibration for measuring deterioration and reading its values at intervals. In recent years, improved diagnostic techniques have become available to monitor the condition of machinery and equipment with sufficient accuracy and consistency to enable practicing CBM.
