ʻO Electromagnetic flowmeter (EMF), i ʻike ʻia ʻo ka magmeter/mag flowmeter, he mea hoʻohana nui ʻia no ke ana ʻana i ka kahe kahe o ka wai conductive uila ma nā noi ʻoihana a me ke kaona. Hiki i ka mea hana ke hāʻawi i kahi hopena ana volumetric kahe hilinaʻi hilinaʻi ʻole e hoʻohana ana i ke kānāwai o Faraday, kūpono no ka wai me ka conductivity kūpono.
Hiki ke hōʻike ʻia kona ikaika electromotive E ma ke ʻano penei:
E=KBVD
Mahea
K= Kawai kahe mau
B= Ka ikaika induction magnetic
V= mean kahe kahe ma ka pauku kea o ke ana paipu
D= Anawaena o loko o ka paipu ana
Kumu Hana
ʻO ke kumu kumu o ka hana ʻana no ka flowmeter mag ʻo ia ke kānāwai o Faraday o ka hoʻokomo electromagnetic. Ua ʻōlelo ʻia, ke neʻe ka mea hoʻokele ma kahi kahua magnetic, e hoʻoulu ʻia ka ikaika electromotive.
Ma kahi o ka hana o ka electromagnetic flowmeter, ka wai conductive e kahe ana ma ka paipu o ka mea hana e like me ka conductor. Hoʻokumu ʻia kahi lua o nā wili i kahi kahua mākēneki like ʻole e pili ana i ke ala kahe. E ʻoki ʻia nā laina mānoanoa ma ke kahe. No laila, hoʻokumu ʻia ka ikaika electromotive i hoʻoulu ʻia a ʻike ʻia e kekahi mau electrodes metala a hana ʻia i mea hoʻopuka hōʻailona uila maʻamau.
Nā pono o ke ana hoʻokahe Magnetic
Ka maʻalahi o ke kūkulu ʻana:ʻAʻohe wahi neʻe i ka hana ʻana o EMF, nona ka nele e hōʻemi i ka ʻaʻahu mechanical a me ka pono mālama. ʻAʻole nō hoʻi ke keʻakeʻa i loko o kāna paipu ana e hiki ke alakaʻi i ka attrition o ke poʻo paʻi a me ka pipili ʻana o ka ʻuala viscous.
ʻO nā pono kau kau liʻiliʻi:Pono ka hoʻokomo ʻana o EMF i ka lōʻihi o nā ʻāpana paipu pololei i luna a i lalo. Ke hana kūʻokoʻa nei, ʻaʻole pono ka mīkini kahe kahe e koi i ka transmitter kaomi ʻokoʻa e kōkua i kāna ana. Hiki ke ana ʻia ke kahe ma nā ʻaoʻao ʻelua, e hōʻemi ana i ka palena no ka hoʻonohonoho ʻana i ka mika a kūpono no nā noi o ka nānā ʻana i ke kahe ʻana.
Hoʻohālikelike:Hiki i ke ana kahe o Mag ke hōʻike i ka hana kūpaʻa a hilinaʻi ʻole i hoʻopilikia ʻia e nā ʻāpana waena kino o ke kaomi, ka mahana, ka nui a me ka viscosity. ʻO nā mea lining hiki ke hoʻopili ʻia a me nā metala electrode cab anti-corrosion a me nā koi kūpaʻa ʻaʻahu, pili i nā laula nui o ke kemika hoʻopaʻapaʻa, abrasive slurry, a me ka maʻemaʻe e koi ana i ka media wai.
pololei:Hōʻike ke ala electromagnetic i ke ana pololei ʻana ma waena o nā ʻano ana ʻana o ke kahe volumetric. ʻO ka pololei ʻo EMF ma ka maʻamau ± 0.5% a i ± 0.2% o ka heluhelu.
Nā palena
Pono ka conductivity:Pono ka wai ana o EMF e lawa ka conductivity (≥5μS/cm). No laila ke kinoea a me ka wai non-conductive ma waho o ka hiki ʻana o ke ana kahe electromagnetic. ʻAʻole hiki ke hoʻohana i kēia ʻano hana nānā ʻana i ka kahe wai, nā mea hoʻoheheʻe organik a me nā huahana ʻaila.
Paipu piha piha:Pono ka hana o EMF i ka hoʻokomo piha ʻana a me ka hoʻopili mau ʻana o nā electrodes me ka wai conductive. No laila, i ka wā o ke ana ʻana, pono e hōʻoia ke kaʻina hana e hoʻopiha piha ʻia ka ʻāpana paipu o EMF me ka medium i mea e hoʻokō ai i ka hana maikaʻi loa.
Palapala noi
Ma muli o kāna ʻano loiloi kūʻokoʻa, kūpono loa ka mīkini kahe electromagnetic no ke ana ʻana i nā wai conductive i nā hiʻohiʻona e like me:
Waiwai:ʻO ke ana ʻana i ka wai maka a me ka kahe wai mālama ʻia no ka hoʻokele waiwai wai.
Ka Lapaʻau Lapaʻau: Ke ana ʻana i ka wai hoʻoheheʻe kūlanakauhale, ka ʻōpala ʻoihana, a me ka ʻōpala me ka conductivity kūpono.
Kemika:Ke ana ʻana i nā ʻakika like ʻole, alkali, nā paʻakai paʻakai, a me nā mea hoʻoheheʻe nui ʻē aʻe me ka hoʻohana ʻana i nā linings a me nā mea electrode.
Mea inu:Ke ana ʻana i nā mea maka, nā mea waena a me nā huahana i hoʻopau ʻia i ka wā o ka hana ʻana i ka waiū, ka wai, ka inu ʻona a me nā mea inu ʻē aʻe.
Metallurgy:Ke ana ʻana i ka slurry mineral, slurry huelo, ka wai slurry lanahu i ka hoʻoili ʻana me nā mea ʻaʻahu.
ikehu:ʻO ke ana ʻana i ka wai anuanu, condensate, nā wai mālama kemika i nā kaʻina hana mana, etc.
Shanghai Wangyuanua ʻoi aku ma mua o 20 mau makahiki o ka hana ʻana a me ka lawelawe ʻana i nā mea hana ana. ʻO kā mākou ʻike ʻoihana nui a me nā noiʻi hihia ma waena o nā kula me nā ʻano mika kahe a pau e hiki ai iā mākou ke hāʻawi i nā hāʻina nānā ʻana i ke kahe e kū pono i kāu mau koi. Inā he nīnau a pono e pili ana i nā mika kahe electromagnetic, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.
