Already Subscribed to this document. Numerical values assigned to the zone boundaries are not intended to serve as acceptance specifications, which should be subject to agreement between the machine manufacturer and customer. Pages with related products.

International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. The values chosen will normally be set relative to a baseline value determined from uso for the measurement oso or direction for that particular machine.

Large land-based steam turbine generator sets in excess of 50 MW — Part 3: Standards Subsctiption may be the perfect solution. Proceed to Checkout Continue Shopping. They assume that the isl are in-situ broad-band values taken under normal steady-state operating conditions. Remember me on this computer. Typically, this will require measuring in two orthogonal radial directions on each bearing cap or pedestal, as shown in figure 1. There may, however, be differences for machines of different design and it is not possible to give clear guidelines for absolute TRIP values.

Amazon Renewed Refurbished products with a warranty. We have no amendments or corrections for this standard. Amazon Inspire Digital Educational Resources. Where the baseline signal is non-steady and non-repetitive, some method of time averaging of the signal 10186-4 required. Such changes can be instantaneous or progressive with time and may indicate incipient damage or some other irregularity.

Draft International Standards adopted by the technical committees are ido to the member bodies for voting. See and discover other items: Significant changes from the normal vibration magnitudes should be investigated so that a dangerous situation may be avoided.

The common measurement parameter for assessing machine vibration severity is velocity. 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.

One criterion considers the magnitude of the observed vibration; the second considers changes in the magnitude. The vibration of newly commissioned machines would normally fall within this zone. It should be noted, however, that the vibration of a gas turbine can be influenced by its mounting system and coupling arrangement to driven machines. Figure 1 shows typical measurement positions. Amazon Giveaway allows you to run promotional giveaways in order to create buzz, reward your audience, and attract new followers and customers.

This standard provides specific guidance for assessing the severity of radial vibration measured on the bearing housings of gas turbines with fluid-film bearings in situ.

BS ISO 10816-4:2009+A1:2017

This includes gas turbines directly coupled to other prime movers such as steam turbines, but the evaluation of the steam turbine vibration is not dealt with in this part of ISO see the following exclusion list. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

The specification of criteria for this, however, is beyond the present scope of this part of ISO 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.

For gas turbines, the measurement system used shall be capable of measuring broad-band vibration over a frequency range from 10 Hz to at least six times the highest shaft rotational frequency. In some cases, these changes would go undetected when using only broad-band vibration measurements see, for example, ISO The characteristics of the measuring system should be known with regard to the effects of the environment including: Two criteria are provided for assessing the machine vibration when operating under steady state conditions.


The basis for this is that the TRIP value is a fixed value corresponding to the maximum vibration to which the machine should be subjected. This standard is also available to be included in Standards Subscriptions. Large land-based steam turbine generator sets in excess of 50 MW.

Shopbop Designer Fashion Brands. Thus, when the criteria of this part of ISO and those of ISO are both applied in the assessment of machine vibration, independent shaft and bearing housing or pedestal vibration measurements should be made. Determination of mechanical vibrations of gear units during acceptance testing.

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.

The following are excluded from this part of ISO I’d like to read this book on Kindle Don’t have a Kindle? Vibration magnitude This criterion is concerned with defining limits for absolute vibration magnitude 10816- with acceptable dynamic loads on the bearings and acceptable vibration transmission into the environment through the support structure and foundation.

However, for long-term condition monitoring purposes and for diagnostics, the use of vibration vector information is 108816-4 useful for detecting and defining changes in the dynamic state of the machine. Machine sets in hydraulic power generating and pumping plants — Part 6: Be the first to review this item Would you like to tell us about a lower price? The zone boundary vibration values were established from representative data provided by manufacturers and users.

Machines with vibration within this zone are normally considered unsatisfactory for long-term continuous operation.
