Ndemanga
Mamita oyenda ndi zida zofunika kwambiri pakuwongolera njira zamafakitale, kuyeza mphamvu, komanso kuyang'anira chilengedwe. Pepalali likufanizira mfundo zogwirira ntchito, mawonekedwe aumisiri, komanso kugwiritsa ntchito ma electromagnetic flow metre, ma ultrasonic flow metres, ndi ma gasi flow metre. Electromagnetic flow metres ndi oyenera kutulutsa zakumwa, ma ultrasound otaya mita amapereka miyeso yolondola kwambiri, ndipo ma mita otaya mpweya amapereka njira zosiyanasiyana zamagasi osiyanasiyana (mwachitsanzo, gasi, mipweya yamafakitale). Kafukufuku akuwonetsa kuti kusankha mita yoyenda yoyenera kungathe kuwongolera kulondola kwa kuyeza (zolakwika <± 0.5%), kuchepetsa kugwiritsa ntchito mphamvu (15% -30% kupulumutsa), ndikuwongolera magwiridwe antchito.
1. Electromagnetic Flow Meters
1.1 Mfundo Yogwirira Ntchito
Kutengera ndi Lamulo la Faraday la Electromagnetic Induction, zakumwa zoyendera zomwe zimayenda kudzera mugawo la maginito zimapanga mphamvu yamagetsi yolingana ndi liwiro loyenda, yomwe imadziwika ndi ma elekitirodi.
1.2 Ntchito Zaukadaulo
- Media Yoyenera: Zakumwa zopangira (conductivity ≥5 μS/cm), monga madzi, ma acid, alkalis, ndi slurries.
- Ubwino:
- Palibe magawo osuntha, osamva kuvala, moyo wautali wautumiki
- Kuchuluka kwa kuyeza (0.1-15 m / s), kutayika kopanda mphamvu
- Kulondola kwakukulu (± 0.2% -± 0.5%), kuyeza koyenda kwapawiri
- Zolepheretsa:
- Osayenera kumadzimadzi osagwiritsa ntchito madzi (monga mafuta, madzi oyera)
- Kutha kusokonezedwa ndi thovu kapena tinthu tolimba
1.3 Ntchito Zofananira
- Madzi a Municipal Water/Wastewater: Large-diameter (DN300+) kayendedwe ka kayendedwe
- Makampani a Chemical: Muyeso wamadzi owononga (mwachitsanzo, sulfuric acid, sodium hydroxide)
- Chakudya/Zamankhwala: Mapangidwe aukhondo (mwachitsanzo, kuyeretsa kwa CIP)
2. Akupanga Mayendedwe Mamita
2.1 Mfundo Yogwirira Ntchito
Kuyeza kuthamanga kwa kuthamanga pogwiritsa ntchito kusiyana kwa nthawi yaulendo (nthawi yonyamuka) kapena Doppler effect. Mitundu iwiri ikuluikulu:
- Clamp-on (Yosasokoneza): Kuyika kosavuta
- Kuyika: Koyenera mapaipi akulu
2.2 Zaukadaulo
- Media Yoyenera: Zamadzimadzi ndi mpweya (mitundu yeniyeni yomwe ilipo), imathandizira kuyenda kwapang'onopang'ono / kosiyanasiyana
- Ubwino:
- Palibe kutsika kwamphamvu, koyenera kumadzimadzi owoneka bwino kwambiri (mwachitsanzo, mafuta osapsa)
- Muyezo waukulu (0.01–25 m/s), kulondola mpaka ±0.5%
- Itha kukhazikitsidwa pa intaneti, kukonza kochepa
- Zolepheretsa:
- Kukhudzidwa ndi zida za chitoliro (mwachitsanzo, chitsulo chotayidwa chikhoza kuchepetsa zizindikiro) ndi homogeneity yamadzimadzi
- Miyezo yolondola kwambiri imafunikira kuyenda kokhazikika (peŵani chipwirikiti)
2.3 Ntchito Zofananira
- Mafuta & Gasi: Kuyang'anira mapaipi akutali
- Ma HVAC Systems: Muyezo wa mphamvu pamadzi ozizira / otentha
- Kuyang'anira Zachilengedwe: Muyezo wa mtsinje/kutuluka kwa madzi osefukira (zitsanzo zonyamula)
3. Mamita Oyenda Gasi
3.1 Mitundu Yaikulu ndi Mawonekedwe
| Mtundu | Mfundo yofunika | Magesi Oyenera | Ubwino wake | Zolepheretsa |
|---|---|---|---|---|
| Thermal Misa | Kutentha kutentha | Mipweya yoyera (mpweya, N₂) | Kuthamanga kwachindunji, palibe malipiro a temp/pressure | Zosayenera ku mpweya wonyowa/fumbi |
| Vortex | Kármán vortex Street | Mpweya, gasi wachilengedwe | Kutentha kwakukulu / kukana kukanikiza | Low tilinazo pa otsika otaya |
| Turbine | Kuzungulira kozungulira | Gasi wachilengedwe, LPG | Kulondola kwakukulu (± 0.5%–±1%) | Imafunika chisamaliro chonyamulira |
| Differential Pressure (Orifice) | Mfundo ya Bernoulli | Mipweya ya mafakitale | Mtengo wotsika, wokhazikika | Kutsika kwakukulu kwanthawi zonse (~ 30%) |
3.2 Ntchito Zofananira
- Gawo la Mphamvu: Kusamutsa kwa gasi wachilengedwe
- Kupanga kwa Semiconductor: Kuwongolera kwa gasi wapamwamba kwambiri (Ar, H₂)
- Kuwunika kwa Emission: Muyezo wa mpweya wa flue (SO₂, NOₓ).
4. Kufananiza ndi Kusankha Malangizo
| Parameter | Mphamvu yamagetsi | Akupanga | Gasi (Chitsanzo cha Thermal) |
|---|---|---|---|
| Media Yoyenera | Zamadzimadzi conductive | Madzi / mpweya | Mipweya |
| Kulondola | ± 0.2%–0.5% | ± 0.5%–1% | ± 1%–2% |
| Kutaya Mphamvu | Palibe | Palibe | Zochepa |
| Kuyika | Chitoliro chonse, pansi | Imafunika kuthamanga molunjika | Pewani kugwedezeka |
| Mtengo | Wapakati-mmwamba | Wapakati-mmwamba | Otsika-pakati |
Zosankha Zosankhira:
- Kuyeza kwamadzimadzi: Electromagnetic for conductive fluids; ultrasonic for non-conductive/corrosive media.
- Kuyeza kwa Gasi: Kutentha kwa mpweya wabwino; vortex kwa nthunzi; turbine kuti asamutsidwe m'manja.
- Zosowa Zapadera: Mapulogalamu aukhondo amafunikira mapangidwe opanda malo opanda malo; zotengera kutentha kwambiri zimafuna zipangizo zosagwira kutentha.
5. Mapeto ndi Zochitika Zamtsogolo
- Ma electromagnetic flow meters amalamulira mafakitale amadzi/madzi, ndikupita patsogolo kwa kuyeza kwamadzimadzi otsika (mwachitsanzo, madzi a ultrapure).
- Mamita otaya akupanga akukula mu kayendetsedwe kabwino ka madzi / mphamvu chifukwa cha zabwino zosalumikizana.
- Mamita oyendera gasi akupita ku kuphatikizika kwa magawo angapo (mwachitsanzo, kubweza kwa temp/pressure + kusanthula kalembedwe) kuti akhale olondola kwambiri.
- Seti yathunthu yamaseva ndi pulogalamu yopanda zingwe yothandizira, imathandizira RS485 GPRS / 4g/WIFI/LORA/LORAWANKuti mudziwe zambiri za ma flowmeter,
