Boholo ba phallo ea phallo bakeng sa calibration ea mitha ea vortex ke bofe?
Ha ho na moeli o le mong oa "universal" oa phallo e phahameng bakeng sa tekanyo ea metha ea vortex-e itšetlehile ka
saese ya metara (DN), mofuta wa mokelikeli (mokeli/gase/mouoane), le meeli ea moetsi. Ho boletse joalo, mekhahlelo e sebetsang ea ho lekanya le meeli ea lebelo e hlalosoa hantle.
1. Mefuta e Tloaelehileng ea Phallo ea Phallo (ho ea ka JJG 1029 & ISO 12764)
- Liquids (metsi, joalo-joalo):
- Likarolo tse fapaneng:0.3 ~ 700 m³/h(DN15–DN200)
- Lebelo le phahameng:10 m/s
- Likhase (moea, khase ea tlhaho):
- Likarolo tse fapaneng:0.5 ~ 7,000 m³/h(DN15–DN300)
- Lebelo le phahameng:60–80 m/s
- Mouoane:
- Likarolo tse fapaneng:0.4 ~ 28,000 m³/h(DN e kholo)
- Lebelo le phahameng:70–80 m/s
2. Meeli ea Bohlokoa e Hlalosang "Max Flow"
- Nomoro ea Reynolds (Re):
- Minimum linear Re:2×10⁴(mokelikeli) /4×10⁴(khase/mouoane)
- Maximum Re:~7×10⁶(moeli o ka holimo oa ho tšolloa ha vortex e tsitsitseng)
- Karolelano ea ho fokotsa chelete: Ka tloaelo10:1(phallo e kholo = 10 × metsotso e phallang)
- Sebaka se nepahetseng sa litekanyo: 20% -80% ea mefuta e meng ea metara(10%–90% bakeng sa mefuta e nepahetseng haholo)
3. Mohlala: DN100 Vortex Meter (Metsi)
- Nominal max flow:120 m³/h(≈4.2 m/s)
- Likarolo tse fapaneng:12–120 m³/h(10:1 phetisetso)
- Lintlha tse nepahetseng tsa ho lekanya:24, 48, 72, 96, 120 m³/h
4. Litlhokahalo tsa Tekanyetso ea Tekanyetso
- Bonyane lintlha tsa tlhahlobo: 6(ho kenyeletsoa min le max flow)
- Mokelikeli: Sebelisa mokelikeli oa 'nete oa tšebetso kapa mokelikeli o nang lee tsamaellanang le nomoro ea Reynolds
Ka bokhutšoanyane: Bakeng sa
metsi, max calibration phallo hangata
~700 m³/h (DN200); bakeng sa
khase,
~7,000 m³/h (DN300). Kamehla tiisa le
letlapa la moetsile
tekanyo ea laboratori ea tlhahlobo.
