Kumvetsetsa Zomwe Ma Electromagnetic Flowmeter Amachita: Kodi Ndi Madzi Otani Amene Angayese?

Ma electromagnetic flowmeter amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kuthekera kwawo kuyeza molondola kayendedwe ka madzi oyendetsera magetsi. Zipangizozi zimadziwika kuti ndi zodalirika komanso zosinthasintha, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana. Komabe, funso lofala ndi lakuti, "Kodi electromagnetic flowmeter ingayese mtundu wanji wa madzi?"

Kuti tiyankhe funso ili, ndikofunikira kumvetsetsa mfundo zomwe zili kumbuyo kwa ma electromagnetic flow meter. Zipangizozi zimagwira ntchito motsatira lamulo la Faraday logwiritsa ntchito ma electromagnetic induction, lomwe limati kondakitala ikadutsa mu magnetic field, voltage imayambitsidwa mu kondakitala. Ndi electromagnetic flowmeter, madzi oyendetsera magetsi amagwira ntchito ngati kondakitala woyenda ndipo magnetic field imapangidwa ndi ma coil a flowmeter. Poyesa voltage yoyambitsidwa, flow meter imatha kudziwa molondola kuchuluka kwa madzi.

Chifukwa cha mfundo yogwirira ntchito imeneyi, ma electromagnetic flowmeters adapangidwa makamaka kuti ayesere kuyenda kwa madzi oyendetsera magetsi. Izi zikutanthauza kuti madziwo ayenera kukhala ndi mulingo winawake wa conductivity kuti flow meter igwire bwino ntchito. Kawirikawiri, madzi omwe ali ndi conductivity yocheperako ya 5 µS/cm (microSiemens per centimeter) ndi oyenera kuyeza pogwiritsa ntchito ma electromagnetic flowmeters.

Zitsanzo zodziwika bwino za madzi omwe angayesedwe pogwiritsa ntchito ma electromagnetic flow meter ndi monga madzi, ma acid, ma alkali, ndi mankhwala osiyanasiyana. Madzi awa nthawi zambiri amakhala ndi milingo yofunikira yoyendetsera kuti atsimikizire kuti kuyenda kwa madzi ndi kolondola. Kuphatikiza apo, momwe ma electromagnetic flow meter amagwirira ntchito mosalowerera zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito ndi madzi owononga kapena owononga chifukwa palibe zinthu zoyenda kapena zolepheretsa mkati mwa njira yoyendera madzi zomwe zingawonongeke.

Ndikofunikira kudziwa kuti ngakhale kuti ma electromagnetic flow meter ndi oyenera kuyeza mitundu yosiyanasiyana ya zakumwa zoyendetsera mpweya, pali zoletsa zina zomwe ziyenera kuganiziridwa. Mwachitsanzo, zakumwa zomwe zimakhala ndi ma conductivity ochepa kwambiri, monga mafuta oyera kapena ma hydrocarbon, sizingakhale zoyenera kuyeza ndi electromagnetic flowmeter. Pankhaniyi, njira zina zoyezera flow monga ultrasound kapena thermal mass flow meter zingakhale zoyenera kwambiri.

Kuphatikiza apo, kukhalapo kwa thovu kapena tinthu tolimba mumadzimadzi kudzakhudza kulondola kwa muyeso wa electromagnetic flowmeter. Madziwo ayenera kusungidwa opanda thovu ndi zinyalala kuti apeze mawerengedwe odalirika a mayendedwe.

Mwachidule, ma electromagnetic flow meter amatha kuyeza mitundu yosiyanasiyana ya zakumwa zoyendetsera magetsi, kuphatikizapo madzi, ma acid, ma alkali, ndi mankhwala. Kapangidwe kake kosasokoneza komanso kulondola kwambiri kumapangitsa kuti akhale chisankho chodziwika bwino choyezera kuyenda kwa madzi m'mafakitale monga kukonza madzi, kukonza mankhwala, komanso kupanga chakudya ndi zakumwa. Komabe, ndikofunikira kuganizira za kuyendetsa bwino kwa madzi ndi ukhondo wa madzi kuti muwonetsetse kuti electromagnetic flowmeter ikugwira ntchito bwino. Pomvetsetsa kuthekera ndi zofooka za electromagnetic flowmeter, ogwiritsa ntchito amatha kupanga chisankho chodziwa bwino za kuyenerera kwawo kugwiritsa ntchito njira inayake yoyezera madzi.
