Machines with vibration within this zone are normally considered unsatisfactory for long-term continuous operation. Gas turbine driven ido excluding aircraft derivatives 1 Scope This part of ISO gives specific guidance for assessing the severity of vibration measured on the bearing housings or pedestals of gas turbine driven sets.
It also includes any driven equipment not included in the exclusion list below.
Two criteria are provided for assessing sio machine vibration when operating under steady state conditions. Shaft vibration measurement requirements and criteria for gas turbine sets are addressed in separate documents, ISO and ISO Pages with related products.
They assume that the measurements are in-situ broad-band values taken under normal steady-state operating conditions. ComiXology Thousands of Digital Comics. Withoutabox Submit to Film Festivals. If the vibration consists mainly of one is component, a simple relationship exists between the peak and r.
Diagnostic investigations should then be initiated to ascertain the reason for the change and to determine what further actions are appropriate. Gas turbine driven sets excluding aircraft derivatives — Part 5: Please first verify your email before subscribing to alerts.
The basis for this is that the TRIP value is a isi value corresponding to the maximum vibration to which the machine should be subjected. Machines with isso within this zone are normally considered acceptable for unrestricted long-term operation. Be the first to review this item Would you like to tell us about a lower price? It is therefore necessary to establish separate criteria for 1816-4 two turbine types. The following are excluded from this part of ISO In addition, different criteria are provided for transient operating conditions, such as run-up and coast-down.
The vibration criteria provided in this part of ISO apply to sio gas turbine sets. The characteristics of the measuring system should be known with regard to the effects of the environment including: Measurements at these locations characterize reasonably well the state of vibration. 1081-64 the time of publication, the editions indicated were valid. It is therefore necessary to establish separate criteria for these two turbine types. Amazon Advertising Find, attract, and engage customers.
To specify the magnitude of vibration beyond which further operation of the machine may cause damage.
Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. There may, however, be differences for machines of different design and it is not possible to give clear guidelines for absolute TRIP values.
This part of ISO gives specific guidance isso assessing the severity of vibration measured on the bearing housings or pedestals of gas turbine driven sets. Large land-based steam turbine generator sets in excess of 50 MW.
BS ISO 10816-4:2009+A1:2017
We have no amendments or corrections for this standard. Explore the Home Gift Guide. 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.
This standard is also iiso to be included in Standards Subscriptions. One criterion considers the magnitude of the observed vibration; the second considers changes in the magnitude.
