Abstract EN
Foil bearing provides compliant support and moderate Coulomb friction for rotor-bearing system, which is conducive to stability and reliability of high speed rotating machinery.
In this paper, both hydrodynamic lubricated foil journal and foil thrust bearings are applied in a 150 m3·h−1 turboexpander for air separation.
In the bearings, protuberant foil is chosen as the supporting subfoil due to its merits of easy fabrication and assembly.
Static loading and deflection of the bearings are tested, respectively, before integration into the turboexpander.
Afterwards, the loading and deflection curves of the journal and thrust bearings are polynomial fitted using least-square method.
Then, performance tests are carried out on the rotor-bearing system, including transient speed-up, high speed, and speed-down processes.
In the tests, the turboexpander supported by the hydrodynamic foil bearings operates smoothly with repeatability.
Maximal rotor speed of the turboexpander reaches 52000 rpm with hydrodynamic lubricated protuberant foil bearings.
