Tlhokahalo ea phaephe e otlolohileng ea "10D holimo le tlase ho 5D" ha se molao o felletseng bakeng sa li-flowmeter tsa ultrasonic tse khomarelang, empa ke tataiso e akaretsang ea ho netefatsa ho nepahala ho hoholo ha tekanyo. Bolelele ba 'nete ba phaephe e otlolohileng bo hlokahalang bo itšetlehile ka lintlha tse kang mofuta oa tšitiso ea phallo, molao-motheo oa ho lekanya (phapang ea nako khahlanong le Doppler), le litlhoko tsa ho nepahala tsa ts'ebeliso.
1. Hobaneng ho kgothaletswa hore ho be le “10D Upstream & 5D Downstream”?
Metjhini ya phallo ya ultrasound e bala sekgahla sa phallo ho latela nako ya phatlalatso (mokgwa wa phapang ya nako) kapa phetoho ya maqhubu (mokgwa wa Doppler) ya maqhubu a ultrasound mokelikeling. Sena se itshetlehile ka phallo e tsitsitseng, e hodileng ka botlalo ya moferefere (ka ho loketseng, boemo ba lebelo le lekanang ho pholletsa le karolo e tsheletseng ya phaephe).
Disebediswa tse kang litsoe, di-tee, di-valve, kapa di-reducer di sitisa boemo ba phallo (ho etsa di-swirls, di-eddies, kapa kabo ya lebelo e sa lekanang), e leng se ka bakang diphoso tsa tekanyo. Tataiso ya "10D upstream + 5D downstream" e fana ka sebaka se lekaneng bakeng sa phallo e sitisitsweng ho tsitsisa hape pele e kena karolong ya tekanyo ya mithara.
2. Liphetoho tse Tenyetsehang: Ke neng “10D/5D” e ka Phomotsoang kapa e Lokelang ho Latelwa ka Tieo?
Bolelele ba phaephe e otlolohileng bo hlokahalang bo fapana ho latela maemo a itseng, joalo ka ha ho bontšitsoe tafoleng e ka tlase:
| Boemo | Bolelele ba Phaephe e Otlolohileng bo Hlokahalang | Lebaka |
|---|---|---|
| Mathata a fokolang a phallo (mohlala, litsoe tse telele tsa radius ea 90°, li-valve tsa heke tse bulehileng ka botlalo) | Ho ea holimo: 5D–8D Tlase ho Noka: 3D–5D | Litšitiso tse bobebe li fela kapele; liphaephe tse khutšoanyane tse otlolohileng li lekane bakeng sa ho tsitsisa phallo. |
| Mathata a tebileng a phallo ea mali (mohlala, litsoe tse khutšoane tsa 90°, li-valve tsa globe, li-tee) | Ho ea holimo: ≥10D Tlase: ≥5D | Ho phethoha/ho phethoha ho matla ho hloka maeto a malelele ho ntlafatsa phallo e tsitsitseng. |
| Lisebelisoa tse nang le ho nepahala ho tlase (mohlala, tlhokomelo e akaretsang ea ts'ebetso, ho latela phallo e seng ea bohlokoa) | Ho ea holimo: 3D–5D Tlase ho Noka: 2D–3D | Ho mamella liphoso tse nyane (±3%–±5%) ho lumella ho tenyetseha haholoanyane. |

3. Litharollo Ha Bolelele ba Phaephe e Otlolohileng bo sa Lekana
Haeba sebaka sa liphaephe se lekanyelitsoe 'me "10D/5D" e ke ke ea finyelloa, mehato e latelang e ka fokotsa tšitiso ea phallo le ho ntlafatsa ho nepahala:
- Kenya di-flow conditioner: Disebediswa tse kang di-tube bundles, di-honeycomb, kapa di-orifice plates di ka otlolla phallo e sitisitsweng ka sebaka se sekgutshwane (ho fokotsa phaephe e otlolohileng e hlokahalang ho ya ho 3D–5D).
- Ntlafatsa sebaka sa ho kenya disensara: Qoba ho kenya disensara ka kotloloho tlase ha ho na le ditshitiso; haeba ho kgoneha, di behe hodima di-elbo/di-valve (ditshitiso tse hodimo ha di na le tshusumetso e nyane ho feta tse tlase).
- Fetola sebaka/sekhutlo sa sensor: Limithara tse ling tse tsoetseng pele tsa ho khomarela li lumella ho lokisoa ha sebaka sa transducer kapa sekhutlo sa mahlaseli ho lefella liphoso tse nyane tsa profil ea phallo.
- Sebelisa li-sensor tsa litsela tse ngata: limithara tse nang le litsela tse peli kapa tse 'ne tsa clamp-on li lekanya lebelo libakeng tse ngata ho pholletsa le karolo e tšelang phaephe, li lekanya ho se leka-lekane ha phallo ho bakoang ke phaephe e otlolohileng e sa lekaneng.

Leha "10D holimo le 5D tlase" e le motheo o sireletsehileng bakeng sa maemo a mangata a indasteri, li-flowmeter tsa ultrasonic tse khomarelang ha li hloke bolelele bona maemong 'ohle. Ntlha ea bohlokoa ke ho bapisa bolelele ba phaephe e otlolohileng le boemo ba tšitiso ea phallo le litlhoko tsa ho nepahala tsa ts'ebeliso. Ha sebaka se lekanyetsoa, li-conditioner tsa phallo kapa li-sensor tsa litsela tse ngata li ka lefella ka katleho phaephe e otlolohileng e sa lekaneng, ho netefatsa ts'ebetso e tšepahalang ea tekanyo.
