Nani Electromagnetic Flowmeter

Nānā nui

ʻO DWP moʻo pipeline type intelligent electromagnetic flowmeter he electromagnetic induction flowmeter, i hoʻolālā ʻia e like me JB/T9248-999 "Electromagnetic Flowmeter", kūpono no ka helu kahe o ka wai conductive me ka conductivity ʻoi aku ma mua o 5us/cm;ʻO ke anawaena nominal he 5 a hiki i ka 3000, he pūʻulu o nā huahana electromagnetic flowmeter e hoʻohui ana i ka naʻauao, liʻiliʻi a me ka māmā hoʻohui, multi-function, precision kiʻekiʻe a me ka hilinaʻi kiʻekiʻe.Aia i ʻelua ʻāpana: sensor a me ka mea hoʻololi akamai.

Loaʻa i ka DWP electromagnetic flowmeter kahi ākea o ka hoʻohana.Hiki iā ia ke hoʻopuka i kahi hōʻailona maʻamau o kēia manawa (4-20mA) e like me ka protocol kamaʻilio HART i ka wā e hālāwai ai i ka nānā ʻana a me ka hōʻike ma ka pūnaewele, no ka hoʻopaʻa ʻana, hoʻoponopono, a me ka mana;hiki ke hoʻohana nui ʻia i ka ʻoihana kemika, ka mālama ʻana i ke kaiapuni, a me ka ʻoihana textile., metallurgy, mining, lāʻau lapaʻau, hana pepa, lako wai, meaʻai, kō, brewing a me nā ʻoihana ʻē aʻe no ke ana kahe wai o ka media conductive i ka pipeline kaʻina;ma waho aʻe o ke ana ʻana i ka wai conductive maʻamau, e like me nā pono kūikawā o nā mea hoʻohana, hiki iā ia ke ana i ka conductive wai-paʻa ʻelua-phase Flow, kahe o nā wai viscosity kiʻekiʻe a me nā wai e like me nā paʻakai, nā waikawa ikaika, a me nā alkali ikaika.

ʻO nā hale

(1) ʻIkepili:

Hoʻokumu nui ʻia ka sensor me kahi catheter ana, kahi electrode ana, kahi coil excitation, kahi hao hao, kahi magnet a me kahi hale.

Ana 'auwaʻa: Ua haku 'ia me ka kuhiliʻole kila conduit, ka uhi a me ka hoʻohui flange, a 'o ia ka mea lawe no ma ka paena ana o ka wai e ana.

Ana electrodes: he mau electrodes i hookomoia ma ka paia o loko o ke ana ana, perpendicular i ke axial kahe kuhikuhi, no laila ke ana ana wai hoailona.

ʻO ka wili hoʻohiwahiwa: ʻO nā wili hoʻohiwahiwa luna a me lalo e hoʻohua ai i kahi māla magnetic i ka catheter ana.

ʻO ke kumu hao a me ka magnetism: Hoʻokomo ʻia ke kahua magnetic i hana ʻia e ka excitation coil i loko o ka wai a hana i kahi kaapuni magnetic.

Shell: ka pahu waho o ka mea kani.

(2) Mea hoʻololi:

He mika lua naʻauao, e hoʻonui i ka hōʻailona kahe a me ka helu ʻana me ka kamepiula hoʻokahi-chip e hōʻike i ke kahe a me ka huina kumulative, a hiki ke hoʻopuka i ka pulse, analog current a me nā hōʻailona ʻē aʻe no ke ana ʻana a i ʻole ka mālama ʻana i ka kahe wai.

(3) Pepa hui huahana:

Hoʻokaʻawale ʻia i ʻelua ʻano: ʻano hoʻohui a me ke ʻano hoʻokaʻawale.

ʻAno hoʻohui: Hoʻokomo ʻia ka sensor a me ka mea hoʻololi i hoʻokahi ʻāpana.

ʻAno hoʻokaʻawale: Hoʻokomo ʻia ka mea ʻike a me ka mea hoʻololi i kahi kaʻawale, a ua hoʻokumu ʻia ka ʻōnaehana kahe kahe ma ka hoʻopili ʻana i nā kaula.I mea e hoʻokō ai i nā koi o ke ana media like ʻole, hiki i ka lining a me nā mea electrode o ka sensor ke loaʻa nā koho he nui.

Kuʻuna hana

Hoʻokumu ʻia ke kumu hana o ka electromagnetic flowmeter ma ke kānāwai o Faraday o ka electromagnetic induction.ʻO ia hoʻi, i ka wā e kahe ai ka wai conductive ma o ka electromagnetic flowmeter, e hana ʻia kahi mana electromotive i hoʻokomo ʻia i loko o ka conductor.ʻO ka ikaika electromotive i hoʻokomo ʻia e like me ka kahe kahe o ka wai conductive, ka ikaika induction magnetic, a me ka laulā o ka conductor (ka anawaena o loko o ka flowmeter), e like me ka mea i hōʻike ʻia ma ke kiʻi.

ʻIke ʻia ka ikaika electromotive i hoʻokomo ʻia e kekahi mau electrodes ma ka paia o ka flowmeter, a hiki ke loaʻa ke kahe kahe ma o ka helu ʻana.

ʻO ka hoʻohālikelike ikaika electromotive i hoʻokomo ʻia: E=KBVD

Ma ke kumu: E hoʻokomo i ka hiki;D ana paipu ana anawaena;

B ka ikaika induction magnetic;V awelika kahe kahe;

K he coefficient e pili ana i ka mahele magnetic field a me ka loa axial.
