Under normal conditions Save 15 % more energy than a single level.
Two stage compression adopts Isobaric ratio is set for interstage pressure
Reduction of compression work by secondary air compression
Air end structure Adopts large rotors. Lower speed. Lower running noise. Case design,including two independent compression units, Improve the installation precision. Helical gear drives directly.each rotor got excellent speed ratio.
Advantages of helical gear Helical gear meshing good, smooth transmission, low noise. The high coincidence degree of helical gear reduces the load of each pair of gear and increases the load capacity of gear The helical gears do not produce a minimum number of roots cut.
Ordinary straight gears enter into meshing at the same time along the tooth width, thus producing shock vibration noise and unstable transmission. Helical cylindrical gear is superior to straight gear and can be used for high speed and heavy load. The transmission torque of helical gear is large, the start is stable and the transmission ratio is fine.
