The prime means of machinery operability support is preventive maintenance. The intervals between maintenance/repairs as well as their size and contents depend on the statistical data. That method does not consider special features of the particular assembly, its actual operation conditions, such as stochastic loads on the machines, or operation procedure, etc. A machinery maintenance system based on such approach has several disadvantages.
Switching from preventive maintenance to condition-based maintenance allows considerably (in a few times) increase run-to-failure period and decrease operational costs. The real-time condition monitoring of machines and their parts ensures an objective assessment of condition during operation. The second component of the innovative technology for maintenance, repair, run-to-failure growth and reduction of cost required for a demanded condition support is detection of faulty parts of the machine before repair and an accurate assessment of their condition after the repair.
