It should 10816-44 noted, however, that the vibration of a gas turbine can be influenced by its mounting system and coupling arrangement to driven machines.

Generally, the machine may be operated for a limited period in this condition until a suitable opportunity arises for remedial action. Machine sets in hydraulic power generating and pumping plants — Part 6: The criteria of this part of ISO are applicable to the vibration measured on the bearing housings or pedestals of gas turbines and driven equipment using fluid-film bearings.

Figure 1 shows typical measurement positions. They assume that the measurements are in-situ broad-band values taken under normal steady-state operating conditions. Unless otherwise specified, no part of this publication may be reproduced or utilized in any form or by any means, electronic or mechanical, including photocopying and microfilm, without permission in writing from the publisher.

The following are excluded from this part of ISO This will, in most cases, be adequate for acceptance testing and for operational monitoring purposes. This lso of ISO gives is guidance for assessing the severity of vibration measured on the bearing housings or pedestals of gas turbine driven sets.

ISO | Jesús arg –

The locations of vibration measurements shall be such that they provide adequate sensitivity to the dynamic forces of the machine but are not unduly influenced by external sources such as combustion vibration, gear mesh vibration, etc.


Since the data showed significant spread, the zone boundary values should be considered only as guidelines. Amazon Restaurants Food ios from local restaurants. Shopbop Designer Fashion Brands.

The operational ALARM settings for a new machine for which there is no prior knowledge of bearing vibration is normally set within zone C. However, these values provide guidelines for ensuring that gross deficiencies or unrealistic requirements are avoided.

Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

Help Center Find new research papers in: Large differences exist between these two turbine types in, for example, casing flexibility, bearing design, rotor to uso weight ratio and mounting structure.

The criteria of this part of ISO are applicable to the vibration measured on the bearing housings or pedestals of gas turbines and driven equipment izo fluid-film bearings.

Shaft vibration ixo requirements and criteria for gas turbine sets are addressed in separate documents, ISO and ISO Figure 1 — Measurement points on main bearings 4 Evaluation ISO provides a general description of the two evaluation criteria used to assess vibration severity on various classes of machines. If application of the different criteria leads to different assessments of vibration severity, the more restrictive zone classification generally applies unless there is significant experience to the contrary.

However, ISO as well as this part of ISO may be revised in the future to give different criteria for gas turbine driven sets mounted on massive concrete foundations and those mounted on lighter, tuned steel foundations, if additional analysis of survey data on such machines shows it to be warranted.

Two criteria are provided for assessing the machine vibration.

If the document is revised or amended, you will be notified by email. Diagnostic investigations should then be initiated to ascertain the reason for the change and to determine what further actions are appropriate.

Such conditions allow for small changes in variables such as generator power output at the normal operating speed. In some cases, these changes iao go undetected when using only broad-band vibration measurements see, for example, ISO We have no amendments or corrections for this standard.

General guidelines 3 Measurement procedures The measurement procedures and instrumentation shall comply with the general requirements of ISO and are as follows. Criterion II is specified on the basis of the change in broad-band vibration magnitude occurring under steady-state operating conditions. Log In Sign 10816–4.

Proceed to Checkout Continue Shopping. In many cases, however, it 1086-4 customary to measure vibration with instruments scaled to read peak rather than r. The specific value is often set by mutual agreement between the customer and the machine manufacturer.

One criterion considers the magnitude of the observed vibration; the second considers changes in the magnitude. Already Subscribed to this document. Pages with related products.
