Reliability increase of piston machines equipped with condition diagnostic and monitoring system (DMS)

Vibration analysis provides a comprehensive assessment of a piston machine’s condition by outer vibration of its casing, and makes an effective instrument for investigating dynamic processes’ quality during assembling, production, defects detection and their critical growth during operation. The highest efficiency rate can be reached by ensuring the condition monitoring of not only a piston machine, but all conjugated mechanisms and attached assemblies.

Internal combustion motors are the most important types of piston machines for which vibration-acoustic diagnostics allows to provide safe accident-free operation with the longest possible operating life.

A DMS is a system (or machine) which product is current information on the condition of the machinery and possible danger, with required commentary (prognosis of residual operating life, prompting on the nearest urgent actions to be made, etc.) and a set risk level.
