Zolepheretsa za Ma Electromagnetic Flow Meters: Nthawi Yosawagwiritsa Ntchito

Ma electromagnetic flow meteramagwiritsidwa ntchito kwambiri poyesa kayendedwe ka madzi m'mafakitale chifukwa cha kulondola kwawo kwambiri, kusakonza bwino, komanso kusowa kwa ziwalo zosuntha. Komabe, sizoyenera kugwiritsa ntchito kulikonse. Munkhaniyi, tikambirana zochitika zomwe ma electromagnetic flow meter sangakhale chisankho chabwino kwambiri, kukuthandizani kusankha chida choyenera kwambiri choyezera kayendedwe ka madzi.

1. Madzi Oyezedwa Ayenera Kukhala Oyendetsa Zinthu

Ma electromagnetic flow meter amagwira ntchito motsatira lamulo la Faraday la Induction, lomwe limafuna kuti madzi oyezedwa akhale ndi mulingo winawake wa magetsi. Kawirikawiri, mphamvu ya madzi iyenera kukhala yoposa mphamvu ya magetsi.5 μS/cm(microsiemens pa sentimita imodzi); apo ayi, mphamvu yamagetsi yomwe yayambitsidwayo idzakhala yofooka kwambiri kuti isayesedwe molondola.

Zochitika Zosayenera:

• Madzi oyera, madzi osasinthidwa kukhala ioni
• Zinthu zopangidwa ndi mafuta (monga mafuta, dizilo)
• Zosungunulira zachilengedwe zomwe zimateteza kwambiri kutentha (monga ether, benzene)

2. Sikoyenera Mafuta, Mpweya, kapena Zouma Kwambiri

Popeza ma electromagnetic flow meter amafuna kuti chitolirocho chidzazidwe ndi madzi kuti chiyezedwe bwino, sichingagwiritsidwe ntchito poyezera mpweya, nthunzi, kapena madzi ouma kwathunthu.

Zochitika Zosayenera:

• Kuyeza mpweya wopanikizika, mpweya wachilengedwe
• Kuyeza kayendedwe ka nthunzi
• Ufa wouma kapena zinthu zophwanyika (monga simenti, tirigu)

3. Madzi Owononga Kapena Otentha Kwambiri Angakhudze Moyo wa Sensor

Ngakhale kuti ma electromagnetic flow meter amatha kukhala ndi ma linings osapsa ndi dzimbiri (monga PTFE) ndi ma electrode (monga Hastelloy, Tantalum), malo ena ovuta kwambiri angakhudzebe kukhazikika ndi moyo wautali wa zidazo. Ma asidi amphamvu, maziko olimba, kapena madzi otentha kwambiri angathandize kukalamba kapena kuwonongeka kwa sensor.

Zochitika Zosayenera:

• Sulfuric acid yokhala ndi kuchuluka kwakukulu, hydrofluoric acid, ndi madzi ena owononga kwambiri
• Madzi okhala ndi kutentha kopitirira kulekerera kwa zinthu (monga, >180°C)

4. Kuthamanga Kochepa kwa Madzi kapena Zakumwa Zokhala ndi Mabowo Zingakhudze Kukhazikika

Ma electromagnetic flow meter amavutika kuyeza kuchuluka kwa madzi otsika (nthawi zambiri pansi pa0.1 m/s) molondola chifukwa mphamvu yamagetsi yomwe imayambitsa ndi yofooka ndipo imatha kusokonezedwa. Komanso, ngati madziwo ali ndi thovu la mpweya wambiri, chizindikirocho chikhoza kusakhazikika, zomwe zimakhudza kulondola kwa muyeso.

Zochitika Zosayenera:

• Kuyeza madzi oyenda pang'ono kwambiri (monga leachate, mankhwala oyezera madzi oyenda pang'ono)
• Zakumwa zokhala ndi mpweya wambiri (monga mankhwala osakaniza atsopano, madzi otayira olowetsedwa ndi mpweya)

5. Malo Okhala ndi Kusokoneza Kwamphamvu kwa Magetsi

Ma electromagnetic flow meter amakhudzidwa ndi kusokonezeka kwa ma electromagnetic akunja. Ngati malo oyikapo ali pafupi ndi ma motors akuluakulu, ma variable frequency drives, kapena ma high-voltage power line, izi zitha kusokoneza kukhazikika kwa miyeso.

Zochitika Zosayenera:

• Pafupi ndi malo osungiramo zinthu kapena mawaya amphamvu amphamvu kwambiri
• Malo amphamvu a mphamvu ya maginito (monga, ma mota akuluakulu, zida zowotcherera)

Pomaliza: Kodi Mungasankhe Bwanji Chiyeso Choyenera Choyezera Kuyenda kwa Madzi?

Ngati ntchito yanu ikukwaniritsa zofunikira izi, choyezera kuyenda kwa magetsi chamagetsi chingakhale chisankho chabwino kwambiri:
✅ Madziwo ndi amadzimadzi ndipo ali ndi mphamvu yokwanira yoyendetsera mpweya
✅ Kutentha ndi kuwononga kwa madziwo kumagwera mkati mwa mulingo wovomerezeka ndi mita
✅ Chitolirocho chadzazidwa ndi madzi, ndipo kuchuluka kwa madzi sikotsika kwambiri
✅ Malo oyikamo zinthu alibe kusokonezedwa kwakukulu kwa maginito amagetsi
