Taw qhia

Electromagnetic dej meter yog ib hom kev ntsuas rau ntsuas qhov ntim ntawm cov kua conductive raws li Faraday txoj cai ntawm electromagnetic induction. Nws muaj cov yam ntxwv ntawm ntau yam, tsis tshua muaj kev khiav dej num, tsis tshua muaj siab poob, kev ntsuas lub sij hawm, kev ntsuas kev ntsuas, kev ntsuas kev taw qhia, thiab lwm yam. Nws tsuas yog siv DMA zoning, kev saib xyuas hauv online, kev soj ntsuam dej tsis zoo thiab kev txheeb xyuas kev sib haum xeeb ntawm cov khoom siv dej. .

Qhov zoo

1 Tsis muaj qhov thaiv hauv qhov ntsuas lub raj, tsis tshua muaj siab poob thiab qhov yuav tsum tau qis rau cov kav dej ncaj.
2 Qhov sib txawv txoj kab uas hla tsim, txhim kho kev ntsuas qhov tseeb thiab rhiab heev, txo qis excitation zog noj.
3 Xaiv cov khoom siv hluav taws xob tsim nyog thiab liner, nrog zoo corrosion kuj thiab hnav tsis kam.
4 Kev tsim hluav taws xob tag nrho, muaj peev xwm tiv thaiv kev cuam tshuam, kev ntsuas txhim khu kev qha, qhov tseeb siab, dav dav.

Daim ntawv thov

Electromagnetic water meter yog ib qho cuab yeej ntsuas tshwj xeeb uas tsim los rau cov kev xav tau tiag tiag ntawm cov chaw lag luam dej, tsim tshwj xeeb rau kev lag luam dej, uas tuaj yeem ua kom zoo dua dej thiab ua kom muaj kev lag luam dej thiab kev sib haum xeeb. Kev xyaum tau ua pov thawj tias electromagnetic water meter yog qhov kev xaiv zoo tshaj plaws los daws qhov kev ntsuas qhov tsis sib xws ntawm cov neeg siv dej loj. Tsis tas li ntawd, cov ntsuas dej electromagnetic tau siv dav hauv kev lag luam tshuaj, kev tiv thaiv ib puag ncig, metallurgy, tshuaj, ntawv ua, dej xa dej thiab cov dej ntws thiab lwm yam kev lag luam thiab kev tswj xyuas.

Kev teeb tsa

Installation ib puag ncig xaiv
1. Nyob deb ntawm cov khoom siv hluav taws xob muaj zog. Xws li lub cev muaj zog loj, loj transformer, loj zaus hloov khoom siv.
2. Lub chaw teeb tsa yuav tsum tsis txhob muaj kev vibration muaj zog, thiab qhov kub thiab txias tsis hloov ntau.
3. Yooj yim rau installation thiab txij nkawm.

Xaiv qhov chaw installation
1. Cov kev taw qhia ntws ntawm lub sensor yuav tsum ua raws li cov kev taw qhia ntws ntawm qhov ntsuas nruab nrab hauv cov kav dej.
2. Lub installation txoj hauj lwm yuav tsum xyuas kom meej tias lub raj ntsuas yog ib txwm sau nrog cov ntsuas nruab nrab.
3. Xaiv qhov chaw uas cov kua dej ntws pulse me me, uas yog, nws yuav tsum nyob deb ntawm lub twj tso kua mis dej thiab cov khoom siv hauv zos (valve, luj tshib, thiab lwm yam).
4. Thaum ntsuas ob-theem kua, xaiv qhov chaw uas tsis yooj yim rau kev sib cais theem.
5. Zam kev teeb tsa hauv cheeb tsam uas muaj qhov tsis zoo hauv lub raj.
6. Thaum ntsuas nruab nrab yooj yim ua rau cov electrode thiab cov phab ntsa hauv lub raj ntsuas kom ua raws li thiab teev, nws raug nquahu tias qhov ntsuas qhov ntsuas hauv lub raj ntsuas tsis tsawg dua 2m / s. Lub sijhawm no, lub raj xaim me me me dua li cov txheej txheem raj tuaj yeem siv. Txhawm rau ntxuav cov electrode thiab ntsuas lub raj yam tsis muaj kev cuam tshuam cov dej ntws hauv cov txheej txheem raj, lub sensor tuaj yeem ntsia tau rau tib lub sijhawm nrog lub tshuab ntxuav.

Upstream ncaj yeeb nkab seem yuav tsum tau
Cov kev xav tau ntawm lub sensor nyob rau hauv cov kav dej ncaj nraim yog qhia nyob rau hauv lub rooj. Thaum lub diameters ntawm cov kav dej ntws thiab cov dej ntws ncaj nraim tsis sib haum nrog cov ntsuas dej txias electromagnetic, cov yeeb nkab tapered lossis tapered yeeb nkab yuav tsum tau nruab, thiab nws lub kaum sab xis yuav tsum tsawg dua 15 ° (7 ° -8 ° yog. nyiam) thiab tom qab ntawd txuas nrog cov yeeb nkab.
