| Popis: |
A new compressor for Gifford-McMahon (G-M) cryocooler service has been designed and built using twin Clever Fellows Innovation Consortium (CFIC) STAR linear motors and special friction-free reed valves compatible with oil-free service. This fully-balanced arrangement eliminates all oil and other condensibles in the helium, as well as providing attitude independence and in-use mobility prohibited by conventional G-M compressors. Secondary oil management components and their failure modes are also eliminated. The design operating point matches pressures and flow for a Sumitomo 408 coldhead. Standard Qdrive 5 kW motors are used, giving significant capacity margin over the baseline compressor’s 6 kW rating. Test results to date have demonstrated design-point flow and pressures, with significantly lower input power than the baseline compressor. The design is reviewed and test results are presented in this paper. |
