                  The principle of compressed air for  turbo compressor


                                       During the air compression, inlet air from inlet port  is filtered through suction filter, the suction rate of air is 

                                       controlled by I.G.V(inlet guide vane) and then, it is supplied into first stage compression part.

                                       The principle of compressed air is that  the  centrifugal force to rotate impeller at high speed accelerates the air

                                       and then, fixed diffuser is changed to pressure.


                                       The R.P.M(revolutions per minute) of impeller is greatly increased by utilizing the difference of gear ratio between

                                       bull gear and pinion gear of the R.P.M of main motor. 

                                       Compressed air to be  increased to about 2 bar at 1st stage is cooled through  inter cooler at first stage and then, 

                                       is supplied into  compression part at second stage.

                                       Cooled air is compressed by second impeller, rotating same speed as first impeller and then, is cooled after 

                                       supplied into second inter cooler.


                                       Compressed air to be  supplied into third stage compression part is compressed again by impeller and is reached 

                                       to optimal design condition through after cooler.

                                       Compressed air to be reached to the finally required pressure condition is supplied into each air receiver tank 

                                       through D.C.V(discharge check valve) in order to protect the reversal of compressed air in the turbo compressor.
