Metal Tube Rotameter E sebelisoa Karachi, Pakistan

Ka Phuptjane, 2018, e mong oa bareki ba rona ba Pakistan, Karachi, ba hloka rotameter ea tube ea tšepe bakeng sa ho lekanya oksijene.

Boemo ba bona ba ho sebetsa ka tsela e latelang:
Pipe: φ70*5, Max. Phallo 110m3/h，Mini.flow 10m3/h，khatello ea ho sebetsa 1.3MPa, mocheso o sebetsang 30 ℃,khatello ea barometric ea lehae 0.1MPa.

Palo ea rona e ka tlase:
① Boima ba oksijene:
Tlas'a maemo a Tloaelehileng:ρ20=1.331kg/m3
Tlas'a boemo ba ho sebetsa:ρ1=ρ20*(P1T20/PNT1Z)=1.331*{(1.3+0.1)*(27+20)/[0.1013*(27+30)*0.992]｝=17.93kg/ m3
② Phallo ea 'Nete:
QS=Q20ρ20/ρ
QSmax=Q20maxρ20/ρ1=110*1.331/17.93=8.166
QSmin=Q20minρ20/ρ1=10*1.331/17.93=0.742
③ Thepa ea tšepe ea rotameter ea boemo bo sebetsang ba 'nete:
QNmax=QSmax/0.2696=8.166/0.2696=30.29
QNmin=QSmax/0.2696=0.742/0.2696=2.75

Tlas'a lipalo tsa rona ka hloko, ts'ebetso e ntle haholo le taolo e tiileng ea boleng, kamora ho kenya, e sebetsa ka mokhoa o phethahetseng, e ntlafatsa ts'ebetso ea mosebelisi oa ho qetela, boleng ba lihlahisoa bo amoheloa haholo ke bareki ba rona.
