Electromagnetic flowmeter hauv kev teeb tsa thiab siv cov txheej txheem yuav muaj qee qhov teeb meem, ua rau muaj teeb meem kev ntsuas, feem ntau yog vim li cas cov flowmeter hauv kev teeb tsa thiab commissioning teeb meem, cov no yog qhov tseem ceeb ntawm kev ua tsis tiav.
1. Nyob rau sab saud ntawm lub ntsuas dej ntws, yog tias muaj cov li qub, lub luj tshib, peb-txoj kev twj tso kua mis thiab lwm yam spoilers, sab pem hauv ntej ncaj yeeb nkab yuav tsum siab tshaj 20DN.
2, lub installation ntawm electromagnetic flowmeter, tshwj xeeb tshaj yog cov polytetrafluoroethylene hauv ob sab phlu cov ntaub ntawv txaus lub sij hawm, lub bolts txuas ob lub flanges yuav tsum xyuam xim rau cov uniform tightening, txwv tsis pub nws yog ib qho yooj yim mus tsoo lub polytetrafluoroethylene hauv ob sab phlu, nrog ib tug torque wrench.
3, thaum lub raj xa hluav taws xob cuam tshuam tam sim no, qhov chaw electromagnetic yoj lossis lub cev muaj zog sib nqus loj cuam tshuam.Stray tam sim no cuam tshuam hauv cov kav dej feem ntau yog ntsuas txaus siab nrog kev tiv thaiv hauv av zoo.Txawm li cas los xij, yog tias lub raj xa dej muaj zog tsis muaj zog tam sim no tsis tuaj yeem kov yeej, nws yog ib qho tsim nyog yuav tsum tau ua kev ntsuas los tiv thaiv cov dej ntws thiab cov kav dej.Qhov chaw electromagnetic yoj cuam tshuam feem ntau yog qhia los ntawm cov teeb liab cable, uas feem ntau yog tiv thaiv los ntawm ib txheej shielding.
4, feem ntau electromagnetic flow meter kuj muaj kev tiv thaiv qib uas yuav tsum tau muaj, feem ntau kev tiv thaiv qib yog IP65, cais hom yog IP68, yog tias tus neeg siv khoom xav tau rau qhov ntsuas ntsuas qhov chaw, qhov chaw teeb tsa hauv av hauv av lossis lwm qhov chaw ntub dej, nws pom zoo kom cov neeg siv khoom. xaiv cais hom.
5, kom tsis txhob cuam tshuam cov teeb liab, lub teeb liab ntawm lub transmitter thiab converter yuav tsum tau kis nrog ib tug shielded hlau, lub teeb liab cable thiab lub hwj chim kab yog tsis tso cai rau muab tso rau parallel nyob rau hauv tib lub cable steel yeeb nkab, lub teeb liab. cable ntev feem ntau yuav tsum tsis pub tshaj 30m.
6, txhawm rau xyuas kom meej tias lub ntsuas hluav taws xob ntsuas hluav taws xob ntsuas lub raj tau ntim nrog qhov ntsuas nruab nrab, nws raug nquahu kom nruab vertically, ntws los ntawm hauv qab mus rau hauv qab, tshwj xeeb tshaj yog rau cov kua-khoom ob-theem ntws, yuav tsum tau nruab vertically.Yog tias tsuas yog kab rov tav kev tso cai rau ntawm qhov chaw, xyuas kom meej tias ob lub electrodes nyob rau hauv tib lub dav hlau kab rov tav.
7, yog tias cov kua ntsuas tau nqa cov khoom, xws li ntsuas sludge, dej phwj tuaj, thiab lwm yam., lub tshuab electromagnetic flowmeter yuav tsum tau nruab vertically, thiab ua kom cov dej ntws tawm hauv qab mus rau hauv qab, kom ntseeg tau tias lub tshuab electromagnetic flowmeter yeej ib txwm muaj tag nrho cov raj, tab sis kuj tseem tuaj yeem ua tau raws li qhov yuav tsum tau ua. zoo txo qhov tsos ntawm npuas.
8. Tus nqi ntws ntawm electromagnetic flowmeter yog nyob rau hauv thaj tsam ntawm 0.3 ~ 12m / s, thiab txoj kab uas hla ntawm lub flowmeter yog tib yam li cov txheej txheem yeeb nkab.Yog tias tus nqi ntws hauv cov raj xa dej qis qis, nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov flowmeter rau qhov ntsuas qhov ntsuas, lossis qhov ntsuas qhov tseeb tsis siab hauv qhov kev khiav dej num no, sim ua kom tus nqi ntws hauv zos hauv qhov ntsuas, thiab txais yuav hom shrink tube.
9, electromagnetic flowmeter tuaj yeem ntsia tau rau hauv cov yeeb nkab ncaj, tuaj yeem ntsia tau rau ntawm kab rov tav lossis inclined yeeb nkab, tab sis yuav tsum muaj cov kab nruab nrab ntawm ob lub electrodes kom nyob rau hauv kab rov tav.
10, electromagnetic flowmeter nyob rau hauv lub tom ntej siv ntawm cov txheej txheem kom huv si ntsuas, tsis tu ncua xyuas qhov teeb meem ntawm lub flowmeter:
(1) Electromagnetic flowmeter sensor electrode hnav, corrosion, to, scaling.Tshwj xeeb tshaj yog rau precipitated, yooj yim kis electrodes, muaj cov khoom theem ntawm cov kua tsis huv;
(2) excitation coil rwb thaiv tsev poob;
(3) Lub rwb thaiv tsev ntawm lub converter txo qis;
(4) Hloov Circuit Court tsis ua haujlwm;
(5) Cov kab txuas txuas puas, luv luv, thiab ntub dej;
(6) Kev hloov tshiab hauv cov cuab yeej ua haujlwm tsis suav nrog.
