Pneumatics machine is to compress aeriform bulk to improve aeriform pressure and the mechanical facility that transport gas, make according to working principle, pneumatics aircraft component is cubage model with speed model, cubage can divide for type of piston, screw, blade type 3 kinds; Speed can divide sort type for centrifugal type and axis two kinds. Discuss principle of work of engine of 6 kinds of common pneumatics today, actor defect and applied limits.
1, piston compressor
2, screw compressor
3, centrifugal compressor
4, rotor compressor
5, the axis sheds compressor
6, blade compressor
Actor defect: Durable, maintenance is little. Main drawback is there is very big mechanical attrition between blade and rotor air cylinder, produce bigger energy loss, efficiency is accordingly inferior.
