NgoJuni, 2018, elinye lamakhasimende ethu ePakistan, eKarachi, lidinga i-rotameter yeshubhu lensimbi lokulinganisa umoya-mpilo.
Isimo sabo sokusebenza simi kanje:
Ipayipi: φ70*5, Max. Ukugeleza 110m3/h，Mini.flow 10m3/h,ingcindezi yokusebenza 1.3MPa, izinga lokushisa lokusebenza 30℃,ingcindezi yendawo ye-barometric engu-0.1MPa.
Ukubala kwethu njengokulandelayo:
①Ukuminyana komoyampilo:
Ngaphansi kwesimo esijwayelekile:ρ20=1.331kg/m3
Ngaphansi kwesimo sokusebenza:ρ1=ρ20*(P1T20/PNT1Z)=1.331*{(1.3+0.1)*(27+20)/[0.1013*(27+30)*0.992]｝=17.93kg/ m3
②Ukugeleza Kwangempela:
QS=Q20ρ20/ρ
QSmax=Q20maxρ20/ρ1=110*1.331/17.93=8.166
QSmin=Q20minρ20/ρ1=10*1.331/17.93=0.742
③Ifomula yesimo sokusebenza se-metal tube rotameter:
QNmax=QSmax/0.2696=8.166/0.2696=30.29
QNmin=QSmax/0.2696=0.742/0.2696=2.75
Ngaphansi kokubala kwethu ngokucophelela, ukucutshungulwa okuhle kakhulu kanye nokulawulwa kwekhwalithi ngokuqinile, ngemuva kokufakwa, kusebenza kahle, kuthuthukisa ukusebenza kahle komsebenzisi wokugcina, ikhwalithi yemikhiqizo ibonwa kakhulu yikhasimende lethu.
