20 GE Centrifugal & Axial Compressors
Centrifugal compressors are carefully tested throughout the manufacturing
process in order to guarantee a perfect match to their design criteria and to
assure long lasting, continuous operation.
The following tests are typically carried out on components and assembled
machines:
- casing: hydraulic pressure test
- impellers: ultrasonic and dye penetrant liquid tests; over speed testing
- impellers/rotors: over-speed testing
- mechanical run test
Optional tests may be performed based on the specific job requirements. For
example:
- performance tests (with air or other gases in an open or closed loop)
- full load - performance tests (including flammable gases) to check rotor
stability and the performance of the machine
- mechanical string test.
Numerous indoor and outdoor test beds together with a sophisticated system
for data acquisition and processing of test results distinguish the Florence,
Massa and Le Creusot facilities.
We have the largest and most complete testing capability in the industry to
perform tests under actual load and pressure conditions (including LNG and
re-injection) for trains driven by gas turbines or electric motors.
