● Currently there are 151 technicians in our technical department, including 2
with master's degree, 98 with bachelor's degree, 20 specialists, one professor-
level senior engineering , and 58 engineers, including 24 senior ones.
● With continuous improvement and re-innovation, our aerodynamic design
technology of 3D flow impeller has reached the world leading level.
● 10,000,000 yuan was invested to build the turbine machinery digital design
platform, which highly improves the R&D ability to the leading level. The
centrifugal compressors designed and manufactured by CQGI were widely used
in many fields especially for nuclear power station & large marine equipments,
as well as petrochemical and coal chemical process.
● We have accumulated engineering experience about research & development
of centrifugal compressor for over 50 years. Based on mature impeller
mechanical design and analysis software, we have constructed integrated
design platform for product development including design analysis ,
performance prediction , 3D geometric design and optimization , overall 3D CFD
flow field analysis , finite element analysis(FEA) , rotor dynamic analysis, and
impeller NC machining , thus realizing fast ,accurate and flexible design for
American Concepts NREC is a leading technical service
company which provides turbo-machinery CAE / CAM technology
all over the world. , CQGI now has its license technology and
advanced software such as COMPAL, AXCENT, MAX5, etc.
COMPAL: this is used to determine geometrical dimension of the
main components, and meanwhile predict the performance curve
under various working conditions. During the designing process,
CQGI has not only made the best of designing and testing models
in Concepts NREC, but also taken advantage of the designing
experience accumulated over the past years and the existing
products as reference
AXCENT: this is used to read statistics from COMPAL, in order for
the molding designing of 3D impellers with ruled and free-form
curved surface, etc, and also for the analysis of quasi 3-D flow
field. The output statistics of impellers is used for manufacturing,
as well as analysis and optimization of CFD in the following step.
After the designing analysis of compressor and 3D geometrical design, there is a
numerical simulation analysis of 3D viscous fluid field by NUMECA FINE/TURBO
software to optimize and improve designing.
