Mu June, 2018, Mmodzi wa kasitomala wathu ku Pakistan, Karachi, iwo amafunikira zitsulo chubu rotameter kuyeza mpweya.
Mkhalidwe wawo wogwira ntchito motere:
Chitoliro: φ70*5, Max. Kuyenda 110m3/h, Mini.flow 10m3/h, ntchito kuthamanga 1.3MPa, kutentha ntchito 30 ℃, m'deralo barometric kuthamanga 0.1MPa.
Kuwerengera kwathu motere:
①Kuchuluka kwa okosijeni:
Pansi pa Mulingo Wokhazikika:ρ20=1.331kg/m3
Pansi pa ntchito:ρ1=ρ20*(P1T20/PNT1Z)=1.331*{(1.3+0.1)*(27+20)/[0.1013*(27+30)*0.992]}=17.93kg/ m3
②Kuyenda Kwenileni:
QS=Q20ρ20/ρ
QSmax=Q20maxρ20/ρ1=110*1.331/17.93=8.166
QSmin=Q20minρ20/ρ1=10*1.331/17.93=0.742
③Chitsulo chachitsulo chozungulira chilinganizo chenicheni chogwirira ntchito:
QNmax=QSmax/0.2696=8.166/0.2696=30.29
QNmin=QSmax/0.2696=0.742/0.2696=2.75
Pansi mawerengedwe athu mosamala, processing wabwino kwambiri ndi mosamalitsa kulamulira khalidwe, pambuyo unsembe, izo zimagwira ntchito mwangwiro, izo bwino mapeto wosuta ntchito bwino, mankhwala khalidwe kwambiri anazindikira ndi kasitomala wathu.
