Waa maxay qiyaasta socodka ugu badan ee cabbirka mitirka vortex-ka?
Ma jiro hal "caalami" oo kala duwan oo socodka ugu badan ee cabbirka mitirka vortex-waxay kuxirantahay
cabbirka mitirka (DN), nooca dareeraha ( dareeraha /gaaska / uumiga), iyo xadka soo saaraha. Taasi waxay tidhi, kala duwanaanta is-habaynta wax ku oolka ah iyo xadka xawaaraha ayaa si wanaagsan loo qeexay.
1. Heerarka socodka is-habaynta caadiga ah (halkii JJG 1029 & ISO 12764)
- Dareeraha (biyaha, iwm.):
- Qiyaasta kala duwanaanta:0.3 ~ 700 m³ /saacaddii(DN15-DN200)
- Xawaaraha ugu badan:10 m /s
- Gaasaska (hawada, gaaska dabiiciga ah):
- Qiyaasta kala duwanaanta:0.5 ~ 7,000 m³ /saacaddii(DN15-DN300)
- Xawaaraha ugu badan:60-80 m /s
- Uumi:
- Qiyaasta kala duwanaanta:0.4 ~ 28,000 m³ /saacaddii(DN weyn)
- Xawaaraha ugu badan:70-80 m /s
2. Xadka Furaha ee qeexaya "Socodka ugu badan"
- Nambarka Reynolds (dib):
- Celceliska ugu yar:2×10⁴(dareere) /4×10⁴(gaas / uumi)
- Dib u celinta ugu badan:~7×10⁶(xadka sare ee daadinta vortex ee deggan)
- Saamiga leexinta: Sida caadiga ah10:1( socodka ugu badan = 10 × min socodka)
- Aaga hagaajinta ugu fiican: 20%-80% ee kala duwanaanshaha magaca mitirka(10%-90% moodooyinka saxda ah ee saxda ah)
3. Tusaale: DN100 Vortex Meter (Biyo)
- socodka ugu badan ee magaca:120 m³ /h(≈4.2 m /s)
- Qiyaasta kala duwanaanta:12-120 m³ /saacaddii(10:1 hoos u dhac)
- Qodobbada sixitaanka ugu fiican:24, 48, 72, 96, 120 m³/h
4. Shuruudaha Jaangooynta
- Dhibcaha imtixaanka ugu yar: 6(ay ku jiraan min iyo socodka max)
- DheecaanIsticmaal dareeraha habka dhabta ah ama dareere lehu dhigma lambarka Reynolds
Marka la soo koobo: Waayo
dareere, socodka cabbirka ugu sarreeya ayaa badanaa ah
~700 m³/saac (DN200); waayo
gaas,
~7,000 m³/saac (DN300). Had iyo jeer ku xaqiiji
xaashida xogta soo saarahaiyo
kala duwanaanshaha shaybaarka cabbirka.
