If you operate or service turbomachinery you should be aware of the most important standards applicable to your machinery.

With regards to vibration of turbomachinery, there ios a few essential standards that will help you in determining the health of your machine, help you monitor it more successfully and ultimately assist you in investigating any design faults or damages.

At the bottom of this page you will find a list of the recommended vibration standards for turbomachinery compiled from our extensive experience in vibration and damage analyses.

This is just a selection of the huge variety of vibration standards which exist see here for a complete list of vibration standards. For most situations the overall amplitude of vibration is the most important assessment criteria, and in this regard the standards are relatively useful. Both of these standards are sub-divided into different parts for machine types. To decide which standard is applicable, see below:.

Follow the links above to our more detailed explanations on using ISO and ISO to evaluate machine vibration, including vibration limits and which is of the standards to apply.

Vibration Standards

As a general rule, machines with rolling-element bearings tend to have high bearing stiffness and are better suited to bearing vibration measurement on the pedestal accelerometers on non-rotating parts. Conversely, machines with fluid-film bearings on soft pedastals are better suited to shaft vibration measurement proximity probes on rotating parts.

If you need assistance contact us here and we can advise you.

For large and critical turbomachinery our general recommendation is jso have at least one a bearing and a one shaft vibration measurement installed at each bearingsince this covers most adequately both the vibration behaviour in the bearing relative vibration, orbits, shaft centreline… as well as exterior fixed body vibrations component resonances, shaft rubbing, flow effects, gear impacts, looseness, misalignment….

The following standards are recommended by Turbo Monitoring for all turbomachinery operators:. Reciprocating Machines above kW.
