High-Performing Bearings for Extreme Operating Conditions
Centrifugal compressors for hydrogen service operate at high rotating speeds and require flexible rotors to accommodate the multiple stages needed to successfully compress the lightweight gas. Waukesha Bearings expertly engineers reliable fluid film bearings that optimize equipment by providing high damping to control vibrations and prevent damage to the rotor and other components. In addition, the bearings deliver accurate and adjustable dynamic performance while operating at high peripheral speeds (120 m/s to 160 m/s). Waukesha Bearings is at the forefront of developing technology for hydrogen compressors, supporting leading OEMs’ pilot and industrial projects.
Turbo-expanders are highly engineered machines that operate under broad speed, loads and gas conditions. In turbo-expander applications, magnetic bearings are immersed in the process gas, which eliminates the need for seals and reduces the impeller overhang. Turbo-expanders for hydrogen liquefaction processes require magnetic bearings that are compatible with the environmental temperatures that can range from ambient to cryogenic conditions. The hydrogen embrittlement phenomena of metals exposed to hydrogen and subject to high stress levels make the selection of the magnetic bearing materials and design features even more critical to machine operation and reliability.
Waukesha Magnetic Bearings has more than 20 years of experience in turbo-expanders operating under high hydrogen concentration (>90%) and has delivered magnetic bearings systems for pure hydrogen liquefaction process.
