Smart Electromagnetic Flowmeter

Dulmar

DWP taxane ah nooca dhuumaha garaadka korantada flowmeter waa socodka induction electromagnetic, loogu talagalay si waafaqsan JB/T9248-999 "Electromagnetic Flowmeter", ku haboon xisaabinta socodka dareere conductive leh conductivity ka weyn 5us / cm;dhexroorka magacu waa 5 ilaa 3000, waa taxane ah alaabada qulqulka elektiroonigga ah ee isku dhafan sirdoonka, isdhexgalka yar yar iyo midka fudud, hawlo badan, saxsanaan sare iyo kalsooni sare.Waxay ka kooban tahay laba qaybood: dareeraha iyo beddelaha smart.

DWP koronto-mareegaha korantada ayaa leh adeegsi badan oo kala duwan.Waxay soo saari kartaa calaamadda hadda jirta ee caadiga ah (4-20mA) si waafaqsan nidaamka isgaarsiinta HART marka ay la kulanto la socodka goobta iyo bandhigga, duubista, hagaajinta, iyo xakamaynta;waxaa si weyn loogu isticmaali karaa warshadaha kiimikada, ilaalinta deegaanka, iyo warshadaha dharka., metallurgy, macdanta, dawooyinka, samaynta waraaqaha, sahayda biyaha, cuntada, sonkorta, breing iyo warshado kale oo loogu talagalay cabbirka dareeraha socodka warbaahinta conductive ee dhuumaha nidaamka;Marka lagu daro cabbiraadda dareeraha guud ee dareeraha, marka loo eego baahiyaha gaarka ah ee isticmaalayaasha, waxay sidoo kale cabbiri kartaa socodka dareeraha-adag ee laba-waji ah, socodka dareeraha viscosity sare iyo dareeraha sida milixda, acids xooggan, iyo alkalis xooggan.

Qaab dhismeedka

(1) Dareemiyaha:

Dareemuhu wuxuu inta badan ka kooban yahay tuubbada cabbiraadda, korantada cabbiraadda, gariiradda kicinta, xudunta birta, magnet iyo guriyeynta.

Biyo-mareenka cabbiraadda: Waxay ka kooban tahay marin-mareenka birta, dahaarka iyo isku xirka flange, waana sidaha goobta goobta lagu cabbirayo dareeraha la cabbirayo.

Cabbiraadda korantada: laba ka mid ah korantada oo lagu rakibay gidaarka gudaha ee marin-biyoodka cabbiraadda, oo ku siman jihada qulqulka axial-ka, si dareeraha cabbirku u soo saaro calaamado.

Gariiradda xamaasadda: Gariiradda sare iyo hoose ee kicinta ee abuurta goob birlabeed kateetarka cabbiraadda.

Xudunta birta iyo magnetismka: Goobta birta ah ee ay dhaliso gariiradda kicinta ayaa lagu soo dhex geliyaa dareeraha waxayna sameysaa wareeg birlab ah.

Shell: baakadaha dibadda ee qalabka.

(2) Beddelka:

Waa mitir sare oo caqli leh, kaas oo kor u qaada signalka qulqulka oo ku xisaabiya kombuyuutar hal-chip ah si uu u muujiyo qulqulka iyo tirada isugeynta, waxayna soo saari kartaa garaaca wadnaha, hadda analogga iyo calaamadaha kale ee cabbirka ama xakamaynta socodka dareeraha.

(3) Foomka isu-ururinta alaabta:

Waxa loo qaybiyaa laba nooc: nooc isku dhafan iyo nooc kala qaybsan.

Nooca isku dhafan: Dareemaha iyo beddelaha ayaa lagu rakibay hal gabal.

Nooca kala qaybsan: Dareemaha iyo beddelaha si gooni ah ayaa loo rakibay, iyo nidaamka cabbirka socodka ayaa la sameeyay iyadoo la isku xirayo fiilooyinka.Si loo daboolo shuruudaha cabbirka warbaahinta kala duwan, xuubka iyo qalabka korantada ee dareemayaasha waxay yeelan karaan doorashooyin badan.

Mabda'a shaqada

Mabda'a shaqada ee qulqulka dareeraha korantada wuxuu ku salaysan yahay sharciga Faraday ee kicinta korantada.Taasi waa, marka dareeraha korantada uu ku dhex socdo qulqulka dareeraha korantada, xoog koronto oo la kiciyay ayaa laga soo saari doonaa kaariyaha.Awoodda koronto-dhaliyaha ee la kiciyay waxay u dhigantaa heerka qulqulka dareeraha korantada, xoojinta kicinta magnetic, iyo ballaca kaari (dhexroorka gudaha ee qulqulka qulqulka), sida ku cad shaxanka.

Awoodda koronto-dhaliyaha ee la kiciyay waxaa lagu ogaadaa labo-elektroodh oo saaran darbiga socodka cabbirka, heerka socodka waxaa lagu heli karaa xisaabinta.

Isla'egta xoogga korantada ee la kiciyay waa: E=KBVD

Qaaciddada: E waxay keentay karti;D dhexroorka tuubada cabbiraadda;

xoojinta kicinta magnetic B;V celceliska xawaaraha socodka;

K waa iskudar la xidhiidha qaybinta goobta magnetic iyo dhererka axial.
