Rau cov khoom siv hluav taws xob muaj hluav taws xob, lub hauv paus ntsiab lus ntsuas ntawm electromagnetic flowmeter yog Faraday txoj cai ntawm electromagnetic induction.Cov qauv ntawm electromagnetic flowmeter feem ntau yog tsim los ntawm magnetic circuit system, ntsuas conduit, electrode, plhaub, hauv ob sab phlu thiab converter.Nws yog tsuas yog siv los ntsuas qhov ntim ntawm cov kua dej conductive thiab slurries hauv cov kav dej kaw.Xws li cov kua qaub, alkalis, ntsev thiab lwm yam kua qaub heev.Cov khoom no yog siv dav hauv roj av, tshuaj lom neeg, metallurgy, textile, khoom noj khoom haus, tshuaj, papermaking thiab lwm yam lag luam, nrog rau kev tiv thaiv ib puag ncig, kev tswj hwm hauv nroog, kev txuag dej thiab lwm yam kev lag luam.
Nyob rau hauv tus txheej txheem ntawm kev siv electromagnetic flowmeter, qee yam khoom siv tsis ua haujlwm yuav tshwm sim.Feem ntau muaj ob hom kev tsis ua haujlwm hauv kev ua haujlwm: ib qho yog qhov tsis ua haujlwm ntawm qhov ntsuas nws tus kheej, uas yog, qhov tsis ua haujlwm tshwm sim los ntawm kev puas tsuaj rau cov txheej txheem lossis cov khoom siv ntawm cov cuab yeej;Qhov thib ob, qhov ua tsis tiav los ntawm kev ua haujlwm sab nraud, xws li kev teeb tsa tsis raug, ntws distortion, deposition thiab scaling, thiab lwm yam.
Thaum lub tshuab electromagnetic flowmeter tsis ua haujlwm, peb feem ntau yuav tsum tau txheeb xyuas qhov twg yog qhov txhaum thiab tom qab ntawd txheeb xyuas seb yuav kho qhov teeb meem li cas.
1. Feem ntau ua txhaum ntawm electromagnetic flowmeter - electromagnetic flowmeter tsis muaj cov teeb liab ntws tawm
Hom kev ua tsis tiav no feem ntau tshwm sim thaum siv, thiab feem ntau yog vim li cas:
(1) Lub hwj chim ntawm lub cuab yeej yog qhov txawv txav;
(2) Kev sib txuas ntawm cable thiab cov zis ntawm lub rooj tsav xwm hluav taws xob yog qhov txawv txav;
(3) Cov kua dej tsis ua raws li qhov yuav tsum tau ua ntawm installation;
(4) Lub sensor Cheebtsam puas lawm los yog muaj ib tug nplaum txheej ntawm lub puab phab ntsa ntawm qhov ntsuas;
(5) Kev puas tsuaj converter Cheebtsam
Yuav daws li cas?
Yog tias qhov no tshwm sim, ua ntej xyuas seb lub hwj chim ntawm qhov ntsuas puas yog qhov tsis raug, paub meej tias cov khoom siv hluav taws xob txuas nrog, xyuas seb qhov tso zis hluav taws xob ntawm lub rooj tsav xwm hluav taws xob puas zoo li qub, lossis sim hloov tag nrho cov khoom siv hluav taws xob los txiav txim siab. seb puas zoo.Xyuas kom paub tseeb tias cov cables tsis zoo thiab txuas kom raug.Tshawb xyuas cov kua dej kev taw qhia thiab cov kua hauv cov yeeb nkab puv.Yog tias tsis muaj kua hauv lub sensor, koj yuav tsum tau hloov lub raj los yog hloov txoj kev mounting.Sim txhim kho nws ntsug.
2. Lub teeb liab ntawm lub electromagnetic flowmeter tau txais me me thiab me me los yog lub teeb liab poob sai sai
Feem ntau ntawm cov kev txhaum no yog tshwm sim los ntawm kev cuam tshuam ntawm kev ntsuas nruab nrab lossis ib puag ncig sab nraud, thiab qhov txhaum tuaj yeem raug tshem tawm ntawm nws tus kheej tom qab kev cuam tshuam sab nraud raug tshem tawm.Txhawm rau kom ntseeg tau qhov tseeb ntawm qhov ntsuas, qhov kev ua tsis tiav no tsis tuaj yeem tsis quav ntsej.Hauv qee qhov chaw tsim khoom, vim muaj kev co loj ntawm cov kav dej ntsuas lossis cov kua dej, lub rooj tsav xwm Circuit Court ntawm lub flowmeter yuav raug loosened, thiab cov nqi tso tawm kuj yuav hloov pauv.
Yuav daws li cas?
(1) Paub meej tias nws yog vim li cas rau kev ua haujlwm ntawm cov txheej txheem, thiab cov kua dej pulsate.Nyob rau lub sijhawm no, lub flowmeter tsuas yog qhia txog qhov txaus ntshai tiag tiag, thiab qhov txhaum tuaj yeem raug tshem tawm ntawm nws tus kheej tom qab lub pulsation xaus.
(2) Electromagnetic cuam tshuam los ntawm cov kev cuam tshuam sab nraud, thiab lwm yam. Xyuas seb puas muaj cov khoom siv hluav taws xob loj lossis cov tshuab hluav taws xob vuam ua haujlwm nyob rau hauv qhov chaw ua haujlwm ntawm lub ntsuas, thiab xyuas kom meej tias cov cuab yeej yog grounded thiab qhov chaw ua haujlwm zoo.
(3) Thaum lub raj xa dej tsis ntim cov kua los yog cov kua muaj cov pa npuas, ob qho tib si yog vim li cas cov txheej txheem.Lub sijhawm no, tus kws tshaj lij tuaj yeem nug kom paub meej tias tus nqi tso tawm tuaj yeem rov qab mus rau qhov qub tom qab cov kua puv puv lossis cov npuas huab cua txias.
(4) Circuit Court board ntawm lub transmitter yog ib tug plug-in qauv.Vim muaj kev co loj ntawm qhov chaw ntsuas cov kav dej lossis cov kua dej, lub hwj chim ntawm lub flowmeter feem ntau loosened.Yog tias nws xoob, lub flowmeter tuaj yeem raug tshem tawm thiab lub rooj tsav xwm hauv Circuit Court tuaj yeem rov kho dua.
3. Qhov zero point ntawm lub electromagnetic flowmeter tsis ruaj khov
Ua rau Analysis
(1) Lub raj xa dej tsis muaj cov kua dej los yog cov kua muaj cua npuas.
(2) Raws li txoj cai, nws ntseeg tau tias tsis muaj cov kua dej ntws hauv lub twj tso kua mis, tab sis qhov tseeb yog qhov me me.
(3) Yog vim li cas rau cov kua (xws li tsis zoo ib yam ntawm cov kua conductivity, electrode pollution, thiab lwm yam).
(4) Lub rwb thaiv tsev ntawm lub teeb liab Circuit Court yog qis dua.
Yuav daws li cas?
Nws yog ib qho tsim nyog los xyuas seb qhov nruab nrab puas muaj cov kav dej thiab seb puas muaj cua npuas hauv nruab nrab.Yog tias muaj huab cua npuas, lub tshuab tshem tawm cua tuaj yeem ntsia tau rau saum cov cua npuas.Kab rov tav installation ntawm qhov ntsuas kuj tuaj yeem hloov mus rau ntsug installation.Xyuas seb qhov ntsuas puas zoo hauv av.Kev tiv thaiv hauv av yuav tsum tsawg dua lossis sib npaug ntawm 100Ω;Lub conductivity ntawm cov conductive nruab nrab yuav tsum tsis txhob tsawg tshaj li 5μs / cm.Yog hais tias qhov nruab nrab accumulates nyob rau hauv lub raj ntsuas, nws yuav tsum tau muab tshem tawm nyob rau hauv lub sij hawm.Tsis txhob khawb hauv ob sab phlu thaum tshem tawm.
