In this paper, the results of thermalCryogenic Industry - CerobearApr 11, 2018CEROBEAR has a long tradition in supplying hybrid ceramic bearings to the cryogenic industry, for Liquefied Gas Pumps (LNG, LN2, LO2, LH2, LHe2) but also Turbo Expanders, Liquid Turbines and Chillers. CEROBEAR bearings for cryogenic applications are designed to fulfil the requests of improving productivity and cutting maintenance costs.
PBS has a long history in the field of cryogenic technology, with its first product on the market being the cryogenic turbine (HEXT 0.5). Since then we have developed additional turboexpander models and have made and distributed hundreds of turboexpanders to our customers and partners, all major players in the field of cryogenic technological processes, with exceptional results.DRIVING EXPANDER TECHNOLOGY - Atlas CopcoOur expander design is simple and provides even and efficient air inlet and outlet. Furthermore, innovative insulation is employed at the expander casing and various other locations within the machine, achieving optimal results. We were, after all, the first expander manufacturer that successfully employed dry-gas seals in cryogenic applications.Dynamic Stability Study of Static Gas Bearing for Small Cryogenic Gas Bearing Turbo ExpanderAug 01, 2011An experimental method is presented to analyze the dynamic stability of the gas bearing for small cryogenic turbo-expanders. The rotation imbalance response and the shape of the rotor orbit were obtained for different speeds up to 110,000 rpm, and the critical speed of the rotor-bearing system was determined by a Bode diagram. An FFT signal analytical method was applied to identify the Cryogenic Gas Bearing Turbo Expander
A cryogenic turbo-expander with active magnetic bearings was made and tested in a reverse-Brayton cycle refrigerator using neon as working fluid. Turbine isentropicExpanders Baker HughesAn expander acts very much like the power turbine in an aeroderivative gas turbine. Flue gas energy is extracted by the rotor blades and converted into rotational energy to generate power. Worldwide network for service. We are single point of contact for plant equipment, installation, commissioning, and service.Expansion Turbines and Refrigeration for Gas Separation Cryogenic Gas Bearing Turbo ExpanderJ.S.

Jan 29, 2014An experimental platform for cryogenic Helium gas bearing turbo-expanders is established at the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences. This turbo-expander experimental platform is designed for performance testing and experimental research on Helium turbo-expanders with different sizes from the liquid hydrogen temperature to the room temperature region.Numerical analysis of the static performance of an annular Cryogenic Gas Bearing Turbo ExpanderFeb 01, 2017The high-speed turbo-expander is an important refrigerating component of the EAST cryogenic system. In the turbo-expander, the axial supporting technology is critical for the smooth operation of the rotor bearing system.
Rated for 85 barA pressure, this 300 kW expander is a single-shaft machine directly coupled with a high-speed generator at 30,000 rpm to avoid gearbox and related auxiliaries. This configuration is completely oil free, as it is supported only on magnetic bearings in a totally sealed case, which avoids gas leakage, flares, and vents to atmosphere.Oil & gas SKFTurbo expanders Thanks to SKF advances, turboexpanders featuring magnetic bearings have become the industrys standard solution for cryogenic applications (NGL, dewpoint, ethylene, LNG).
