Shop Full-Load Testing Of Centrifugal Compressors
MetadataShow full item record
The high reliability traditionally required of turbocompressors has become even more imperative in recent years, due to increased unit power and the extreme environmental conditions of many applications. These machines are now often used in highly demanding compression service, such as reinjection and sea pipelines. In these applications there have been, unfortunately, some examples of malfunctioning. As a result, machines are often requested to undergo all possible testing before leaving the factory. Full-load tests are now being requested in addition to the more traditional no-load mechanical and performance tests. In the field of natural gas machinery, full-load tests were initially performed mainly for the purpose of verifying the rotor-dynamic stability of compressors at high pressure, as well as their overall performance. Subsequently, full-load testing of the complete compression system (driver, coupling and gear, lube and seal oil systems, control system, coolers, etc.) was performed. Finally, testing was carried out on the entire module.
