Such as three kinds of high flow impeller with the United States developed a pipeline compressor impeller efficiency up to 94% to 95%; efficiency levels in Japan uniaxial multistage centrifugal compressor further enhance its high-volume semi-heads Open Impeller adiabatic efficiency of 94%. Its regulatory approach will be greater use of steam turbine or gas turbine driven to change the speed to save energy.
