A watan Yuni, 2018, Daya daga mu abokin ciniki a Pakistan, Karachi, suna bukatar karfe tube rotameter domin auna oxygen.
Yanayin aikin su kamar haka:
Bututu: φ70*5, Max. Gudun 110m3 / h, Mini.flow 10m3 / h, matsa lamba aiki 1.3MPa, zafin aiki 30 ℃, matsa lamba barometric na gida 0.1MPa.
Lissafinmu kamar haka:
①Yawan Oxygen:
Ƙarƙashin daidaitaccen yanayin: ρ20 = 1.331kg /m3
Karkashin yanayin aiki: ρ1=ρ20*(P1T20/PNT1Z)=1.331*{(1.3+0.1)*(27*+20)/[0.1013*(27*+30)*0.992]｝=17.93kg/ m3
②Gaskiya Tafiya:
QS=Q20ρ20/ρ
QSmax=Q20maxρ20/ρ1=110*1.331/17.93=8.166
QSmin=Q20minρ20/ρ1=10*1.331/17.93=0.742
③ The karfe tube rotameter real yanayin aiki dabara:
QNmax=QSmax/0.2696=8.166/0.2696=30.29
QNmin=QSmax/0.2696=0.742/0.2696=2.75
A karkashin mu a hankali lissafin, m aiki da kuma tsananin ingancin iko, bayan shigarwa, shi aiki daidai, shi inganta karshen mai amfani ta aiki yadda ya dace, da kayayyakin ingancin ne sosai gane da abokin ciniki.
