Therefore, it should be combined with other requirements to fulfill the purchaser objectives. In most cases, the test is conducted on an inert gas medium having a higher k value than the specified gas resulting in higher discharge temperature.

These tests can be performed in combination too. The position of the compressor on this plot does not determine if the compressor will be stable or not. You do not have access to this content.

Compressors Shop performance test of turbo-compressors. As an example, if the test procedure requires an investigation on the low flow portion of the operating map, the speed might have to be reduced to avoid over-pressurizing the test loop. Compressors American Petroleum Institute. The effect of the annular gas seals is critical for high-pressure high-density compressors. Accordingly, purchasers share centtrifugal responsibility of a suitable design.

API 8th Edition says to use the machine condition at the normal operating point unless the supplier and purchaser agree upon another operating point. In some cases, it might be necessary to reduce the speed during certain steps of the test.

This is an important verification, especially for the axial bearing, which is not subjected to significant load during the mechanical running test or the performance test. The position on the plot and the results of an API Level I log dec analysis with the journal bearings, squeeze-film dampers if used and oil-film seals if used and an anticipated cross-coupling as in MemmottAPI 7th Editionand API 8th Edition are used to determine if a more detailed API Level II log dec analysis with inclusion of the gas annular seals is needed.

In most cases, the test is conducted on an inert gas medium having a higher k value than the specified gas resulting in higher discharge temperature. You either do not have a subscription or your subscription has expired. Moreover, it attempts to address critical sections of the standard and share practical comments on specific clauses. Although most machines that undergo a FPFLFS test would already have passed a mechanical running test at maximum continuous speed, such tests could replace the mechanical running test without compromises.

Citing articles are presented as examples only. CompressorsAmerican Petroleum Institute. Full Compressoor The full pressure condition permits the evaluation of the compressor for the mechanical integrity of its components, such as pressure containing components not only the casingdry gas seals, as well as bearings mechanical behavior and temperature rise.

The mechanical integrity of components is also evaluated, since the compressor is operating at full pressure and full speed. If stability testing was done only during a mechanical run test it would help to validate compgessor combined rotor-bearing-pedestal system model, but it would not validate the dynamic modeling of the annular gas seals and that of the load related anticipated cross-couplings.
