Chofunika kwambiri pakupanga magetsi ndi chofunika kwambiri posankha mita yoyezera magetsi. Mosiyana ndi makina oyezera magetsi kapena makina oyezera magetsi, makina oyezera magetsi amafuna kuti madzi oyezerawa akhale ndi mphamvu zamagetsi kuti apange chizindikiro choyezera.
Kawirikawiri, ma electromagnetic flow meter ambiri amafuna ma electromagnetic conductivity a madzi a:
≥ 5 μS/cm (microsiemens pa sentimita)
Ma electromagnetic flow meter ena ogwira ntchito kwambiri amatha kuyeza zakumwa zomwe zimakhala ndi conductivity yochepa, koma kuti muyezo wodalirika komanso wokhazikika, conductivity yoposa 5 μS/cm nthawi zambiri imalimbikitsidwa.
Chifukwa Chiyani Kuyenda kwa Maginito Kumakhudza Kuyeza kwa Mita Yoyendera Maginito?
Choyezera kuyenda kwa maginito chamagetsi chimagwira ntchito motsatira lamulo la Faraday la Electromagnetic Induction.
Madzi oyendetsera magetsi akadutsa mu mphamvu ya maginito yopangidwa ndi sensa, mphamvu yamagetsi yoyambitsidwa imapangidwa. Ma electrode omwe amaikidwa mkati mwa sensa amazindikira chizindikiro cha mphamvu yamagetsi ichi, ndipo chosinthira magetsi chimawerengera liwiro la kayendedwe ka magetsi.
Mphamvu ya chizindikiro chopangidwacho imadalira mphamvu yamagetsi ya madzi.
Ngati mphamvu ya madzi m'thupi ndi yotsika kwambiri:
* Chizindikiro cha magetsi chomwe chimayambitsa chimakhala chofooka kwambiri.
* Ma electrode sangathe kuzindikira chizindikiro chokhazikika.
* Zotuluka zimatha kusinthasintha.
* Choyezera kuchuluka kwa madzi m'thupi chingawonetse kuchuluka kwa madzi osakhazikika kapena olakwika.
Chifukwa chake, kuyendetsa bwino magetsi ndi chimodzi mwazinthu zazikulu zomwe zimakhudza magwiridwe antchito a mita yoyendera magetsi.
Zofunikira Zachizolowezi Zoyendetsera Ma Conductivity pa Zamadzimadzi Zosiyanasiyana
Zakumwa zosiyanasiyana zimakhala ndi milingo yosiyanasiyana ya conductivity.
Mapulogalamu Oyenera
Ma electromagnetic flow meter amagwiritsidwa ntchito kwambiri pa zakumwa monga:
Madzi a pampopi
* Kawirikawiri ndi yoyenera kuyeza maginito.
Madzi otayira
* Kugwiritsa ntchito bwino kwambiri chifukwa madzi otayira nthawi zambiri amakhala ndi mchere ndi ma ayoni osungunuka.
Madzi opangira mafakitale
* Yoyenera nthawi zambiri.
Ma acid ndi ma alkali
* Kawirikawiri zimayesedwa ngati mphamvu yamagetsi ndi yokwanira.
Dothi ndi zamkati
* Yoyenera chifukwa cha ma ayoni osungunuka ndi tinthu tomwe timapachikidwa.
Mapulogalamu Okhala ndi Ma Conductivity Otsika
Madzi ena ali ndi mphamvu yochepa kwambiri yamagetsi ndipo sangakhale oyenera kuyeza kayendedwe ka magetsi.
Zitsanzo zikuphatikizapo:
Madzi oyera
Madzi oyera kwambiri amakhala ndi mphamvu yotsika kwambiri yoyendetsera magetsi, nthawi zina pansi pa malire oyezera a mita yoyendera magetsi.
Mapulogalamuwa akuphatikizapo:
* Madzi opangira ma semiconductor
* Madzi oyera a m'chipatala
* Machitidwe amadzi opangidwa ndi deionized
Muzochitika izi, ma ultrasound flow meters nthawi zambiri amakhala chisankho chabwino.
Zakumwa za Hydrocarbon
Zakumwa monga:
* Mafuta
* Dizilo yamafuta
* Petroli
* Mafuta a hydraulic
ali ndi mphamvu yotsika kwambiri yoyendetsera magetsi ndipo nthawi zambiri sangayesedwe ndi ma electromagnetic flow mita wamba.
Njira zina zamakono zingaphatikizepo:
* Miyezo yoyezera kuchuluka kwa madzi mu Coriolis
* Zoyezera kuyenda kwa turbine
* Zoyezera kuyenda bwino kwa madzi
* Ma ultrasound flow meter (kutengera momwe amagwiritsidwira ntchito)
Kodi Mungayang'anire Bwanji Kuyenda kwa Madzi Musanasankhe Chiyeso Choyezera Kuyenda?
Musanasankhe choyezera kuchuluka kwa madzi mu electromagnetic flow meter, ndi bwino kuyang'ana izi:
1. Kapangidwe kapakati
Kumvetsetsa ngati madziwo ali ndi:
* Mchere wosungunuka
* Mchere
* Asidi kapena alkali
* Tinthu toyendetsa
Madzi okhala ndi ma ayoni nthawi zambiri amakhala ndi mphamvu yoyendetsa bwino.
2. Mtengo Weniweni wa Kuyendetsa Magalimoto
Kuchuluka kwa mphamvu yamagetsi kuyenera kuyesedwa malinga ndi momwe zinthu zilili pa ntchito yeniyeni.
Zinthu zofunika ndi izi:
* Kutentha kwamadzimadzi
* Kuchuluka kwa mankhwala
* Mikhalidwe ya ndondomeko
Kusinthasintha kwa mpweya kumatha kusintha kwambiri ndi kutentha ndi kukhazikika.
Kodi Chimachitika N'chiyani Ngati Kuthamanga Kwamagetsi Kuli Kochepa Kwambiri?
Ngati mphamvu ya conductivity ili pansi pa zomwe zimalimbikitsidwa, ogwiritsa ntchito angakumane ndi izi:
Zotuluka Zosakhazikika
Kuthamanga kwa madzi komwe kukuwonetsedwa kungadumphe kapena kusinthasintha ngakhale pamene kuyenda kwenikweni kuli kokhazikika.
Cholakwika Chosayenda Bwino
Chosinthira sichingazindikire chizindikiro chokwanira ndipo chingawonetse kuyenda kwa zero.
Kulondola Kosalondola
Mtengo woyezedwa ukhoza kukhala ndi kusiyana kwakukulu kuposa momwe unkayembekezeredwa.
Mayankho a Mapulogalamu Otsika a Kutulutsa Mphamvu
Ngati mphamvu ya madzi ikufanana ndi zomwe zimafunika, njira zingapo zitha kuganiziridwa:
1. Tsimikizirani Kuyendetsa Koyenera kwa Magalimoto
Nthawi zina vutoli limayamba chifukwa cha malingaliro olakwika okhudza mphamvu zamadzimadzi. Kuyeza mphamvu yeniyeni ya madzi kungathandize kudziwa ngati ndi yoyenera.
2. Sankhani Choyezera Mayendedwe a Magetsi Choyenera
Ma electromagnetic flow meter ena apamwamba athandiza kwambiri kukonza ma signal ndipo amatha kuthana ndi ma conductivity ochepa bwino.
3. Sankhani Ukadaulo Woyesera Njira Yina
Ngati mphamvu ya madzi m'thupi ndi yotsika kwambiri, ganizirani izi:
* Choyezera kuyenda kwa ma ultrasound cholumikizira
* Choyezera kuyenda kwa ma ultrasonic chamkati
* Choyezera kuyenda kwa madzi a Coriolis
Kusankha kumadalira mtundu wa madzi, kufunikira kolondola, kukula kwa chitoliro, ndi momwe zimakhalira poyika.
Kodi Kutentha Kumakhudza Kuyendetsa Ma Conductivity?
Inde. Kuchuluka kwa madzi m'thupi kumasintha malinga ndi kutentha.
Kawirikawiri:
* Kutentha kwambiri kumawonjezera mphamvu ya conductivity.
* Kutentha kotsika kumachepetsa mphamvu ya conductivity.
Mwachitsanzo, mphamvu ya madzi yomwe imayesedwa pa 20°C ikhoza kukhala yosiyana ndi mtengo wa 60°C.
Chifukwa chake, kuwunika kwa conductivity kuyenera kuganizira kutentha kwenikweni kwa ntchito.
Mphamvu yocheperako yoyendetsera magetsi yomwe imafunika pa ma electromagnetic flow meter ambiri ndi pafupifupi 5 μS/cm. Madziwo ayenera kukhala ndi mphamvu yoyendetsera magetsi yokwanira kuti apange chizindikiro cha voltage choyezeka pakati pa ma electrodes.
Ma electromagnetic flow meter ndi abwino kwambiri pa zinthu zoyendetsera mpweya monga madzi, madzi otayira, mankhwala, ndi matope. Komabe, sizoyenera zinthu zoyendetsera mpweya monga mafuta, mafuta, ndi madzi oyera kwambiri.
Musanasankhe choyezera kuyenda kwa magetsi chamagetsi, nthawi zonse tsimikizirani momwe madzi amayendera, kutentha, ndi momwe amagwirira ntchito kuti muwonetsetse kuti muyeso wake ndi wodalirika komanso wolondola.
