Guided-rotor compressor
{{Short description|Type of positive-displacement rotary gas compressor}}
The guided-rotor compressor (GRC) is a positive-displacement rotary gas compressor. The compression volume is defined by the trochoidally rotating rotor mounted on an eccentric drive shaft[http://www.grcompressor.com/#section2 GRC - Detailed description and defining geometry][http://www1.eere.energy.gov/hydrogenandfuelcells/pdfs/liquefaction_comp_pres_praxair.pdf Hydrogen delivery liquefaction & compression] {{webarchive|url=https://web.archive.org/web/20120314052342/http://www1.eere.energy.gov/hydrogenandfuelcells/pdfs/liquefaction_comp_pres_praxair.pdf |date=2012-03-14 }} with a typical 80 to 85% adiabatic efficiency.{{Cite web |url=http://www.canadianpurcell.com/UserFiles/File/MechanicalPerformanceFeaturesGRC.doc |title=Mechanical properties |access-date=2009-10-24 |archive-url=https://web.archive.org/web/20110708113337/http://www.canadianpurcell.com/UserFiles/File/MechanicalPerformanceFeaturesGRC.doc |archive-date=2011-07-08 |url-status=dead }}
History
File:Guided Rotor Compressor.svg
The development of the GRC started in 1990 to minimize the use of compressor valve plates and springs by using simple inlet/discharge ports.[http://www.grcompressor.com/#section11 Development history]
Uses
The guided-rotor compressor is under research as a hydrogen compressor for hydrogen stations and hydrogen pipeline transport.[http://corridoreis.anl.gov/documents/docs/technical/APT_61012_EVS_TM_08_2.pdf Overview of interstate hydrogen pipeline systems]
