Lub vortex flowmeter tuaj yeem ntsuas qhov ntws ntawm cov pa roj, kua thiab chav dej, xws li ntim ntws, huab cua ntws, ntim ntws, thiab lwm yam. Qhov ntsuas qhov ntsuas tau zoo thiab qhov tseeb yog siab.Nws yog hom kev ntsuas dej ntau tshaj plaws hauv cov kav dej thiab muaj qhov ntsuas tau zoo.
Kev ntsuas ntau ntawm vortex flowmeter yog qhov loj, thiab qhov cuam tshuam ntawm qhov ntsuas me me.Piv txwv li, kua ntom ntom, siab, viscosity, thiab lwm yam yuav tsis cuam tshuam rau qhov ntsuas kev ua haujlwm ntawm Vortex Flougeter, yog li cov kev coj ua yog tseem muaj zog heev.
Qhov zoo ntawm vortex flowmeter yog nws qhov ntsuas loj.Kev ntseeg siab, tsis muaj kev saib xyuas txhua yam, vim tias tsis muaj cov khoom siv kho tshuab.Nyob rau hauv txoj kev no, txawm tias lub sij hawm ntsuas ntev, cov zaub tsis tuaj yeem ruaj khov.Nrog lub siab sensor, nws tuaj yeem ua haujlwm nyob rau hauv qhov kub thiab txias ib puag ncig nrog lub zog adaptability.Ntawm cov cuab yeej ntsuas zoo sib xws, vortex flowmeter yog qhov kev xaiv zoo tshaj plaws.Tam sim no, ntau lub tuam txhab siv cov cuab yeej no los ntsuas tus nqi zoo dua thiab raug.
Piv txwv li: 0.13-0.16 1 / L, koj tuaj yeem kwv yees qhov bai koj tus kheej, ntsuas qhov dav ntawm kab peb sab, thiab Straw du Hall parameter nyob nruab nrab ntawm 0.16-0.23 (xam ntawm 0.17).
f=StV/d formula (1)
Nyob qhov twg:
f-Carman vortex zaus generated ntawm ib sab ntawm lub tshuab hluav taws xob
St-Strohal tus lej (tsis muaj tus lej)
V- qhov nruab nrab ntws tus nqi ntawm cov kua
d-qhov dav ntawm lub tshuab hluav taws xob vortex (nco lub tsev)
Tom qab xam qhov zaus
K=f*3.6/(v*D*D/353.7)
K: flow coefficient
f: Ntau zaus generated ntawm tus nqi ntws
D: Flow meter caliber
V: Flow tus nqi
Vortex flowmeter ntau yam xaiv
Kev ua haujlwm thiab version ntawm lub tshuab hluav taws xob dawb thiab Du lub zog amplifier ntawm vortex flowmeter yog txawv.
