"Air fan maintenance mode" blade is the key to progress in wind energy technology core wind turbine components, its good design, reliable quality and superior performance is the determining factor to ensure normal and stable operation of the unit. "Air fan maintenance mode" Although China's current wind turbine technology is not fully mature, but relatively large domestic market share stations centrifugal fan manufacturers have their own set of technologies, will open the learning gap of foreign advanced technology, to enhance domestic technology provide the conditions. "Air fan maintenance mode" blade is the key to progress in wind energy technology core wind turbine components, its good design, reliable quality and superior performance is the determining factor to ensure normal and stable operation of the unit. And with the air chamber is designed to meet one of the blades will increase the pressure, increase the amount of wind.
