Bishii Juun, 2018, Mid ka mid ah macaamiishayada Pakistan, Karachi, waxay u baahan yihiin rotameter tube birta si loo cabbiro ogsijiinta.
Xaaladooda shaqo sida hoos ku qoran:
Dhuumaha: φ70*5, Max. Socodka 110m3 / h, Mini.flow 10m3 / h, cadaadiska shaqada 1.3MPa, heerkulka shaqada 30 ℃, cadaadiska barometric maxaliga ah 0.1MPa.
Xisaabintayadu sida hoos ku qoran:
Cufnaanta Ogsajiinta:
Hoosta heerka caadiga ah:ρ20=1.331kg/m3
Hoosta xaalada shaqada: ρ1=ρ20*(P1T20/PNT1Z)=1.331*{(1.3+0.1)*(27*+20)/[0.1013*(27*+30)*0.992]｝=17.93kg/ m3
② Socodka dhabta ah:
QS=Q20ρ20/ρ
QSmax=Q20maxρ20/ρ1=110*1.331/17.93=8.166
QSmin=Q20minρ20/ρ1=10*1.331/17.93=0.742
③Tuubada birta rotameterka qaacidada shaqada dhabta ah:
QNmax=QSmax/0.2696=8.166/0.2696=30.29
QNmin=QSmax/0.2696=0.742/0.2696=2.75
Under our xisaabinta si taxadar leh, processing heer sare ah iyo si adag u kontoroolka tayada, ka dib markii la rakibo, waxa ay u shaqeysaa si fiican, waxa ay hagaajinaysaa waxtarka shaqada dhamaadka user ee, tayada alaabta waxaa si heer sare ah loo aqoonsan yahay macaamiishayada.
