Ukungena kwe-nitrojeni kunokudibana nomoya ocinezelweyo jikelele, uxinzelelo lwe-nitrogen turbine compressor luphezulu, uhlobo lwegiya lugcina amandla ngakumbi.

I-oksijeni ngokuhambelana nomgca woxinzelelo lwe-cylinder eyodwa (uxinzelelo oluphantsi) kunye ne-cylinder ezimbini (uxinzelelo oluphezulu kunye ne-cylinder yoxinzelelo oluphantsi) (inqanaba le-8 loxinzelelo kwi-bar ye-30), ngokubanzi ngaphantsi kwe-30 barg, kufuneka umise i-5 barg yokutywina igesi ( uxinzelelo nitrogen angahlangana), kwangaxeshanye, ngenxa yeoksijini medium ubushushu eliphezulu uxinzelelo oluphezulu HuoHuan izizathu, yonke flow inxalenye amkele ingxubevange yobhedu, kufuneka ukuseta ukhuseleko nitrogen, ngokuqhelekileyo ngokuqwalasela uyilo lobunjineli;Ixabiso lokungena kweoksijini evela kumazwe angaphandle liphezulu, malunga namaxesha aphindwe kabini kunasekhaya, awasetyenziswanga jikelele, okwangoku zonke zijinga ukungena kweoksijini, uxinzelelo lokukhupha 3∽30barG, ukuhamba kwe8000Nm³/h ngasentla kunokuhlangatyezwa.Nangona kunjalo, isantya sokuhamba sincinci kwaye i-oksijini yokwazi ukungena iphantsi, ngokubanzi yi-8000Nm³/h (55%) ∽80000Nm³/h (68%).

Okuqhelekileyo kusetyenziswe kwinkqubo yoxinzelelo lwe-oxygen, ukusuka kwi-3 ~ 30 barg, kodwa rhoqo ngenkqubo yoxinzelelo lwangaphakathi lwe-booster (ngokubanzi ngaphezu kwe-70% yokusebenza kakuhle, nayo inezithintelo zendlela, ukusebenza kakuhle kuphezulu kune-oksijini ngokusebenzisa amanqaku angaphezu kwe-10, inokuphelisa ucinezelo ngokwentelekiso kancinane kuxinzelelo emva kobushushu iadvanteji yelahleko yamandla eyongezelelweyo, kodwa ucinezelo lwangaphakathi loxinzelelo lwentsimbi kufuneka luphuculwe, ukuze kuthintelwe ukuguquguquka kwenkqubo yokutshintshiselana kobushushu) kuthelekiswa, kunye nokusetyenziswa kwamandla emva kokuba isicwangciso simisiwe. .

Zeziphi iinkampani ezaziwayo kweli shishini?
