Kev faib tawm ntawm electromagnetic flowmeter

Electromagnetic flowmeter yog ib hom induction meter raws li Faraday txoj cai ntawm electromagnetic induction los ntsuas qhov ntim ntawm cov khoom nruab nrab hauv lub raj. Cov coil zoo siab nyob rau hauv cov raj xa hluav taws xob tsim hluav taws xob sib nqus, thiab qhov ntsuas nruab nrab ntws los ntawm cov raj xa mus los txiav cov kab sib nqus, thiab ua kom muaj peev xwm ua rau ob lub electrodes nrhiav pom, thiab nws qhov loj me yog proportional rau qhov ceev ntawm cov dej txav. Cov yeeb nkab ntsuas yog hluav taws xob cais tawm los ntawm cov kua dej thiab ntsuas electrode los ntawm cov ntaub ntawv uas tsis yog-conductive (rubber, tetrafluorofluoride, po, thiab lwm yam). Tom qab lub teeb liab hluav taws xob hloov pauv tau ua tiav, thiab tom qab ntawd ua tiav los ntawm microprocessor, cov teeb liab tso tawm yog linear nrog tus nqi ntws, uas yog siv los ntawm cov cuab yeej nram qab rau kev kaw lus, hloov kho thiab tswj, thiab tuaj yeem sib txuas lus nrog lub computer sab saud los ntawm RS485.

1. Cov yam ntxwv

Electromagnetic flowmeter tsis muaj qhov txav mus los thiab qhov chaw tawm hauv cov kua dej, muaj kev ntseeg siab, siv los ntsuas ntau yam kua qaub, alkali, ntsev tov, pulp, syrup, dej phwj tuaj, npias, wort, xws li cov kua dej ntws tawm thiab lwm cov khib nyiab tshem tawm, gasification chav thiab cov khoom viscous ntws. Tsis tas li ntawd, vim nws qhov kev ua tau zoo sealing zoo, nws kuj tuaj yeem siv rau cov kav dej thiab cov kav dej hauv av.

2. Daim ntawv thov

Electromagnetic flowmeter yog tam sim no dav siv nyob rau hauv lub hwj chim, tshuaj, ib puag ncig tiv thaiv, metallurgy, tshuaj, ntawv ua, zaub mov, dej thiab kua thiab lwm yam kev lag luam technology thiab kev tswj departments, siv los ntsuas ntau yam acid, alkali, ntsev tov, pulp, syrup, dej phwj tuaj thiab lwm yam conductive fluid flow, sanitary electromagnetic flowmeter yog ua los ntawm stainless hlau, yuav siv tau rau npias, wort, dej kho mob thiab lwm yam txaus ntsuas.

3. Kev ntsuas qhov tseeb

Electromagnetic flowmeters tsis cuam tshuam los ntawm cov kev hloov pauv hauv cov kua dej ntom ntom, viscosity, kub, siab thiab conductivity, thiab lub sensor induced voltage teeb liab muaj ib qho kev sib raug zoo nrog qhov nruab nrab ntws tus nqi, yog li qhov ntsuas qhov tseeb yog siab, feem ntau 1%. Vim tias qhov ntsuas no yuav tsum muaj kev sib raug zoo ntawm qhov kev sib txuas ntawm cov kav dej thiab qhov impedance ntawm qhov ntsuas ntsuas, thaum qhov ntsuas qhov nruab nrab yog li 10 ohms · cm, nws pib tsim teeb meem hauv kev tsim khoom, thiab thaum lub conductivity qis dua. , lub suab nrov thermal nce ntau nrog qhov nce ntawm kev ua haujlwm sab hauv.

4, Qhov zoo ntawm electromagnetic flowmeter

Ntsuas qhov qhib ntws hauv cov yeeb nkab, yog li tsis muaj kev poob siab ntxiv; Tsis muaj qhov txav mus los hauv cov yeeb nkab ntsuas, yog li lub sijhawm sensor lub neej ntev heev. Tsuas yog cov hauv ob sab phlu thiab electrode ntawm lub sensor yog nyob rau hauv kev sib cuag nrog cov ntsuas ntsuas, thiab ntev npaum li cov electrode thiab cov ntaub ntawv hauv ob sab phlu raug xaiv, lawv tuaj yeem tiv taus corrosion thiab hnav. Lub anti-corrosion electromagnetic flowmeter tuaj yeem ua los ntawm cov ntaub ntawv tshwj xeeb los ua cov electrodes thiab hauv ob sab phlu, thiab tuaj yeem ntsuas yuav luag tag nrho cov xov xwm corrosive.

5, Txhim kho ib puag ncig kev xav tau

A. Lub sensor yuav tsum tau muab tso rau hauv qhov chaw qhuav thiab qhov cua, zam qhov chaw ntub dej thiab yooj yim dej nyab, thiab sim ua kom tsis txhob muaj tshav ntuj ncaj qha thiab los nag.

B. Tsis txhob nruab rau hauv qhov chaw uas qhov kub thiab txias siab dhau. Lub electromagnetic flowmeter ntawm lub cev qauv kuj raug rau qhov kub thiab txias ntawm cov khoom siv hluav taws xob, uas yog qis dua.

C. Yuav tsum tsis txhob muaj qhov hluav taws xob muaj zog ntawm lub raj xa dej uas lub sensor tau teeb tsa, thiab nws yuav tsum nyob deb ntawm cov khoom siv hluav taws xob muaj zog, xws li cov khoom siv hluav taws xob loj thiab cov khoom siv hluav taws xob loj, kom tsis txhob muaj kev cuam tshuam ntawm electromagnetic teb;

D. Lub raj xa dej lossis hauv av uas lub sensor tau teeb tsa yuav tsum tsis txhob muaj kev vibration muaj zog, tshwj xeeb tshaj yog cov twj paj nruag;

E. Qhov kub thiab txias ntawm lub converter installation yog nruab nrab ntawm -10 thiab 45 degree ; Cov av noo ntawm huab cua Tsawg dua lossis sib npaug li 85%; Tsis muaj zog vibration ntawm qhov chaw installation; Cov huab cua ib puag ncig tsis muaj corrosive gases; Cov converters yuav tsum tau nruab rau hauv tsev kom ntau li ntau tau. Thaum ntsia sab nraum zoov, ntsuas yuav tsum tau coj los tiv thaiv lub hnub thiab nag.
