Description
Strong of 60 years of innovation and design in the field of cryogenic turbomachines, Air Liquide Advanced Technologies is constantly developing new products. Magnetic bearings technology is used since the mid 80’s for specific applications where reliability and efficiency is a key issue. 50 cold compressors, 5 pumps and 5 high power turbomachines (moto-compressors, moto-turbo-compressors and turboalternators) have been delivered in the past years and 29 magnetic bearings turbomachines will be delivered by ALAT in 2017. The first supercritical helium pump of Air Liquide new standard range of cryomachine was commissioned successfully in 2016 for the JT60 project. The compression map of the pump was measured and in very good accordance with the calculations. A new 175kW turbomachine installed on Turbo-Brayton refrigeration system has been commissioned and characterized in 2016. The compression map of the centrifugal compressors and the efficiency of the turbine have been measured. This paper presents the commissioning results of these 2 new turbomachines on magnetic bearings.
