Metal Tube Rotameter Inoshandiswa muKarachi,Pakistan

Muna Chikumi, 2018, Mumwe wevatengi vedu muPakistan, Karachi, ivo vanoda simbi chubhu rotameter yekuyera iyo oxygen.

Mamiriro avo ekushanda senge pazasi:
Pipe: φ70*5,Max. Kuyerera 110m3/h，Mini.flow 10m3/h，kushanda kudzvanywa 1.3MPa，kushanda tembiricha 30℃,iyo yomunharaunda barometric pressure 0.1MPa.

calculation yedu sepazasi:
①Kuwanda kweokisijeni:
Under Standard condition:ρ20=1.331kg/m3
Pasi pemamiriro ekushanda:ρ1=ρ20*(P1T20/PNT1Z)=1.331*{(1.3+0.1)*(27+20)/[0.1013*(27+30)*0.992]｝=17.93kg/ m3
②Kuyerera chaiko:
QS=Q20ρ20/ρ
QSmax=Q20maxρ20/ρ1=110*1.331/17.93=8.166
QSmin=Q20minρ20/ρ1=10*1.331/17.93=0.742
③Iyo simbi chubhu rotameter chaiyo yekushanda mamiriro formula:
QNmax=QSmax/0.2696=8.166/0.2696=30.29
QNmin=QSmax/0.2696=0.742/0.2696=2.75

Pasi pekuverenga kwedu nekuchenjerera, kugadzirisa kwakanakisa uye kunyatso kudzora kwemhando, mushure mekuisa, inoshanda nemazvo, inovandudza kushanda kwemushandisi wekupedzisira, mhando yezvigadzirwa inocherechedzwa zvakanyanya nemutengi wedu.
