SUP-LUGB Vortex flowmeter popanda kutentha & kubwezera kukakamiza

• Mfundo yoyezera

  Madzi amadzimadzi oyenda ndi liwiro linalake ndikudutsa chopinga chokhazikika amatulutsa mafunde.M'badwo wa vortices umadziwika kuti Karman's Vortices. Kuchuluka kwa vortex kukhetsa ndi mzere wolunjika wa liwiro lamadzimadzi komanso ma frequency amatengera mawonekedwe ndi m'lifupi mwa nkhope ya thupi la bluff.

Popeza m'lifupi mwa kutchinga ndi m'mimba mwake wa chitoliro adzakhala mochuluka kapena mocheperapo, pafupipafupi amaperekedwa ndi mawu akuti:

f=STV/d

Mu formula:
f - Karman vortex frequency opangidwa mbali imodzi ya bluff body (Hz)
Nambala ya St - strouhal (nambala yosakhala ya dimensional)
V - pafupifupi liwiro lamadzimadzi (m/s)
d - m'lifupi mwake (m)

• Kuyika

  Kulumikizana kwa Wafer: DN15-DN300 (PN2.5MPa yoyamba)

  Kulumikizana kwa Flange: DN15-DN50(choyambirira PN2.5MPa)
