At present cent is compressor of air of market main trend machine of cubage type pneumatics and machine of dynamical formula pneumatics, among them cubage type compressor is divided again for screw pneumatics machine, machine of reciprocating type pneumatics, eddy hangs pneumatics machine to wait, machine of dynamical formula pneumatics is centrifugal pneumatics machine.

Screw machine is divided again for machine of pneumatics of fuel injection screw, without machine of oily screw pneumatics, without machine of pneumatics of oily tine coming back, without machine of grease screw pneumatics, but market of machine of water screw pneumatics is not common.

I can introduce later period the working principle of machine of each type pneumatics, common breakdown and settle way, pneumatics machine how type selecting.

One. Machine of pneumatics of fuel injection screw

Market of machine of pneumatics of fuel injection screw is very common, what do not have exorbitant requirement to reducing air quality is OK machine of pneumatics of screw of choice fuel injection, the sort of pneumatics machine and produce tolerance a lot of more alternative, can undertake choosing according to using a case.

2. Pneumatics machine type selecting

  1. Compress air quality not to have exorbitant requirement to back end
  2. Of back end yield with what tolerance reachs unit pressure
  3. Reduce functional effect, can choose to be versed in frequency star triangle is started, also can choose frequency conversion to start
  4. The means of back end refrigeration of pneumatics machine, one kind is wind cold refrigeration, one kind is water-cooling refrigeration, need to decide according to the circumstance.
