Vacuum Pressure Swing Adsorption Oxygen Production Plant (VPSA-O2Shuka)

  • Abincin yau da kullun: iska
  • Kewayon iya aiki: 300 ~ 30000Nm3/h
  • O2tsarki: har zuwa 93% by vol.
  • O2matsin lamba: bisa ga buƙatun abokin ciniki
  • Aiki: atomatik, PLC sarrafawa
  • Abubuwan amfani: Don samar da 1,000 Nm³/h O2 (tsarki 90%), ana buƙatar abubuwan Utilities masu zuwa:
  • Ingancin ƙarfin babban injin: 500kw
  • Ruwa mai sanyaya mai kewayawa: 20m3 / h
  • Ruwan rufewa: 2.4m3 / h
  • Iskar kayan aiki: 0.6MPa, 50Nm3/h

* Tsarin samar da iskar oxygen na VPSA yana aiwatar da ƙira na “na musamman” bisa ga tsayin daka daban-daban na mai amfani, yanayin yanayi, girman na'urar, tsabtar oxygen (70% ~ 93%).
