Ma nā ʻāpana ʻoihana e like me ke kemika, metallurgy, ka mālama ʻana i ka wai ʻino, ka pepa a me ka eli ʻana, hōʻike pinepine nā mea o ke ana ʻana o ke kahe i nā ʻano paʻakikī e pili ana i ka corrosive a i ʻole ka viscous. ʻO nā mea ana kahe maʻamau e like me ka orifice plate a i ʻole nā meter flow vortex e kū pinepine i nā pilikia e like me ke clogging, wear, corrosion failure a i ʻole ka nalowale o ka pololei i ka wā e hana ai me ia ʻano. Ke hoʻohana nei i kāna loina ana kū hoʻokahi a me nā hiʻohiʻona hoʻonohonoho, ʻo kamika kahe electromagneticʻo ia ka mea hana makemake ʻia no ke ana ʻana o ke kahe o nā mea lepo a ʻinoʻino i ke kahua o ka kaohi ʻana i ke kaʻina hana ʻoihana.
Hana ka mika kahe electromagnetic ma muli o ke kānāwai o Faraday no ka hoʻokomo electromagnetic. Kuhikuhi ke kumumanaʻo e hilinaʻi wale nā mika kahe electromagnetic i ka conductivity uila o ka wai a kūʻokoʻa ia i nā mea e like me ka nui o ka wai, ka viscosity, ka mahana a me ke kaomi. Ma ke ʻano kūkulu, ʻo ka paipu ana o kahi mika kahe electromagnetic he hale, liner a me nā electrodes. Aia ka liner i ka pilina pololei me ke kaʻina hana, e hāʻawi ana i ka pale insulation a me ka corrosion; ua hoʻokomo ʻia nā electrodes i loko o ka liner a hana i ka pilina me ka wai e ʻike i ka ikaika electromotive i hoʻokomo ʻia; hāʻawi ka hale i ka ikaika mechanical a kākoʻo i ke kaapuni magnetic. Hoʻokumu kēia hoʻonohonoho hoʻonohonoho i ke kumu no ka hoʻololi ʻana i nā kūlana hana koi.
ʻO ka mea maʻamau, loaʻa i nā mea paʻa i hoʻokuʻu ʻia, nā olonā a i ʻole nā ʻāpana viscous i loko o nā mea lepo. ʻO nā mea hoʻoluliluli, nā ʻāpana wili, a i ʻole nā wahi kahe liʻiliʻi i loaʻa pinepine i nā mika kahe kuʻuna he mea maʻalahi loa ia i ka paʻa ʻana a i ʻole ka ʻaʻahu ʻana. ʻO nā pono o ka mika kahe electromagnetic ma lalo o ia mau kūlana hana e hōʻike nui ʻia ma nā ʻano ʻelua:
ʻAno hana ʻole ke keakea:ʻO ke kahawai ana o ka mika kahe electromagnetic he paipu pololei me ka ʻole o nā ʻāpana e puka ana a neʻe paha i loko. Ke kahe nei ke wai ma o ka mea hana, ʻaʻohe loli koke i ka ʻāpana kea, e pale ana i nā ʻāpana paʻa a i ʻole nā loea mai ka hōʻiliʻili ʻana i loko o ka mea hana. Ke hoʻohālikelike ʻia me nā ʻano mika kahe kaomi like ʻole, hoʻopau ka mika kahe electromagnetic i ka pilikia o nā puka kaomi paʻa; me nā mika kahe turbine a me nā neʻe maikaʻi, pale ia i ka hāʻule ʻana i hana ʻia e ka hopu ʻana o ka rotor a i ʻole ka ʻaʻahu.
Hoʻololi i ke kahe ʻelua-paepae paʻa-wai:Hiki ke kūpaʻa ka hōʻailona o ka mika kahe electromagnetic ke loaʻa nā ʻāpana paʻa i loko o ka medium no ka mea ua hoʻoholo mua ʻia ka ikaika electromotive i hoʻokomo ʻia e ka wikiwiki o ke kahe o ka pae hoʻomau wai. Eia kekahi, hoʻohana ka mika kahe electromagnetic i ka hoʻonāukiuki alapine kiʻekiʻe a me ka ʻenehana hana hōʻailona kikohoʻe e kāohi pono ana i ka walaʻau spike i hana ʻia e nā ʻāpana e hoʻopilikia ana i nā electrodes, e mālama ana i ka pololei kiʻekiʻe i ke ana ʻana o nā kahe wai paʻa e like me ka pulp, slurry a me ka mud.
Hoʻokau nā ʻano waikawa ʻino like ʻole, nā alkalis, nā hopena paʻakai, a me nā mea hoʻoheheʻe organik i nā koi koʻikoʻi i ke kūpaʻa ʻana i ka pala o nā mea i pulu ʻia e ka mika kahe. Hoʻokō ka mika kahe electromagnetic i ka hoʻokaʻawale pono a me ke ana hilinaʻi o nā mea ʻino ma o ka synergy ma waena o ka lining a me ka mea electrode.
Mea uhilawelawe i ka hana o ka hoʻopili pololei ʻana i ka medium a hoʻokaʻawale iā ia mai ka hale metala. Ma muli o nā ʻano corrosive o ka medium, hiki ke koho ʻia nā mea e like me PTFE, polyurethane, a i ʻole chloroprene rubber. Hōʻike ka PTFE inertness kemika maikaʻi loa, hiki ke kū i ka erosion mai ka hapa nui o nā media corrosive koe wale nō nā metala alkali i hoʻoheheʻe ʻia a me kekahi mau fluorides, ʻoiai he mau waiwai anti-adhesion maikaʻi.
Mea uilaua koho ʻia ma muli o nā ʻano pala electrochemical waena. ʻO nā mea i hoʻohana pinepine ʻia e komo pū me SS316L, Hastelloy B/C, titanium, tantalum a me nā platinum alloys. No ka waikawa corrosive ikaika a i ʻole nā hoʻonā i loaʻa nā ion chloride, hiki i nā electrodes tantalum a platinum paha ke hāʻawi i ka palekana hilinaʻi. Ma o ke koho ʻana i nā mea lining a me nā electrode, hiki i ka electrode flowmeter ke hoʻololi i nā ʻano hana like ʻole mai ka ʻālohilohi a hiki i ka corrosive nui.
Loaʻa i ka mika kahe electromagnetic kekahi mau hiʻohiʻona piha e hiki ai ke ana i nā mea lepo a me nā mea ʻino:
Pohō Paʻi Haʻahaʻa:Ma muli o ka nele o ka element throttling, ʻaneʻane ʻaʻohe pohō kaomi hou i ka wā o ke ana ʻana me ka mika kahe electromagnetic hiki ke lilo i mea nui no ka medium viscosity kiʻekiʻe a i ʻole ka ʻōnaehana hana me ka mana lawe palena ʻia.
Paʻa Kiʻekiʻe no ka Wā Lōʻihi:ʻAʻohe ʻāpana neʻe o ka mika kahe electromagnetic, e pale ana i nā pilikia e like me ka luhi mechanical, ka ʻaʻahu a i ʻole ka hopu ʻana. Inā koho pono ʻia nā mea lining a me nā electrode, hiki ke ʻoi aku ka maikaʻi o kona kūpaʻa hana lōʻihi ma mua o nā mika kahe mechanical a i ʻole throttling, me ka hoʻemi nui ʻia o nā koi mālama.
Eanakahi kahe lectromagnetichōʻike i nā pono kūikawā i ke ana ʻana i ka media lepo/corrosive. Eia nō naʻe, ua kūkulu ʻia ka pono o kekahi hopena loea ma luna o ke kumu o nā kūlana kūpono. He mea nui loa ia e hoʻomaopopo i ka mea mua no ke ana ʻana o ka electromagnetic flowmeter ʻo ia ka mea i ana ʻia e loaʻa i kahi pae o ka conductivity uila (ʻaʻole maʻamau ma lalo o 5 ~ 15μS/cm). No nā wai ʻaʻole alakaʻi a i ʻole nā wai conductivity haʻahaʻa e like me ka wai deionized, nā mea hoʻoheheʻe hydrocarbon, a me nā aila, ʻaʻole hiki i ke kumumanaʻo ke hoʻoulu i kahi ikaika electromotive i hoʻokomo ʻia a hoʻokumu i ke ana hiki.Shanghai Wangyuanhe mea hana mea kani ʻoihana me ka ʻoi aku o iwakālua mau makahiki o ka ʻike ʻoihana. Inā he mau pono a nīnau paha kāu e pili anaana kahekoho, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou no ke kākoʻo loea a me nā hoʻonā.
