Electromagnetic flowmeter (EMF), oo sidoo kale loo yaqaan magmeter/mag flowmeter, waa aalad si weyn loo isticmaalo oo lagu cabbiro heerka socodka dareeraha korantada ee codsiyada warshadaha iyo degmada. Qalabku wuxuu bixin karaa xal la isku halayn karo oo aan faragelin lahayn oo cabbiraadda cabbirka qulqulka mugga taasoo ka faa'iidaysanaysa sharciga Faraday, oo ku habboon dhexdhexaad dhexdhexaad ah oo leh dhaqdhaqaaq ku habboon.
Awoodeeda korantada ee ay keentay E waxa lagu muujin karaa qaacidooyinka soo socda:
E=KBVD
Halkee
K= Joogtada socodka hawada
B= xoojinta kicinta magnetic
V= xawaaraha socodka celceliska ee qaybta cabbirka ee tuubada cabbirka
D= Dhexroorka gudaha ee tuubada cabbiraadda
Mabda'a Shaqada
Mabda'a aasaasiga ah ee hawlgalka mag flowmeter-ka waa sharciga Faraday ee kicinta korantada. Waxa ay sheegaysaa in marka kirishbooyuhu uu dhex maro goob birlab ah, in xooga elektromotiga la soo jiidi doono.
Gaar ahaan marka laga hadlayo hawlgalka socodka mitirka korantada, dareeraha korantada ee ku qulqulaya tuubada aaladda ayaa u adeegta sidii kirishbooyada. Labada gariirood ayaa soo saara goob birlabeed isku mid ah oo u siman jihada socodka. Xadhkaha xadhkaha birlabeedka waxa lagu gooyaa qulqulka. Awoodda koronto-dhaliyaha ee la kiciyay ayaa markaa la soo saaray oo dabadeed lagu dareemaa lammaane koronto oo bir ah waxaana loo habeeyey soo saarista calaamadaha korantada ee caadiga ah.
Faa'iidooyinka Cabbiraadda socodka magnetic
Fududeynta qaabdhismeedka:Dhismaha EMF ma laha qaybo dhaqaaqa, kuwaas oo maqnaanshahooda ay yareeyaan daalka farsamada iyo baahida dayactirka. Waxa kale oo ay adagtahay in wax xannibaad ahi ka jiro gudaha tuubada cabbiraadda taas oo keeni karta in madaxa cadaadisku xidhmo iyo xidhmo dhexdhexaad ah oo viscous ah.
Shuruudaha kor-u-qaadista oo yar:Rakibaadda EMF waxay u baahan tahay dherer gaaban oo kor iyo hoosba qaybaha tuubooyinka tooska ah. U shaqaynta si madax bannaan, mag-flowmeter uma baahna gudbiyaha cadaadiska kala duwan si uu u caawiyo cabbirkiisa. Socodka waxaa lagu qiyaasi karaa labada jiho, hoos u dhigista xaddidaadda jihada mitirka waxayna ku habboon tahay codsiyada kormeerka socodka gadaasha.
Waafaqid:Cabbirka qulqulka Mag wuxuu soo bandhigi karaa waxqabad xasiloon oo la isku halayn karo oo si dhib leh u saameeya xuduudaha dhexdhexaadka jirka ee cadaadiska, heerkulka, cufnaanta iyo viscosity. Qalabka dahaarka ah ee la cusboonaysiin karo iyo biraha elektiroonigga ah ee cabbitaanka ka-hortagga daxalka oo xidha dalabaadka adkaysiga leh, ee lagu dabaqi karo noocyo badan oo kiimiko ah oo gardarra ah, slurry abrasive, iyo nadaafadda u baahan warbaahin dareere ah.
Saxnimada:Habka Electromagnetic wuxuu muujinayaa cabbiraad sax ah oo ka mid ah hababka cabbirka socodka mugga ee kala duwan. Saxnaanta EMF guud ahaan waa ± 0.5% ilaa ± 0.2% akhriska.
Xaddid
Hab-dhaqanka ayaa loo baahan yahay:Dheecaanka cabbiraadda EMF ayaa looga baahan yahay inuu yeesho dhaqdhaqaaq ku filan (≥5μS/cm). Sidaa awgeed gaaska iyo dareeraha aan shaqaynayn ayaa ka baxsan awoodda cabbirka socodka korantada. Warbahinta caadiga ah ee warshadaha aan shaqayn sida biyaha la safeeyey uumiga, dareerayaasha organic iyo alaabta saliidda ma awoodaan inay isticmaalaan habkan kormeerka socodka.
Dhuumaha si buuxda loo buuxiyey:Hawlgalka EMF wuxuu u baahan yahay quusin buuxda iyo xidhiidhka joogtada ah ee korantada leh dareeraha korantada. Sidaa darteed inta lagu jiro cabbirka geeddi-socodku waa inuu xaqiijiyaa in qaybta tuubada ee EMF ay si buuxda u buuxisay dhexdhexaad si loo gaaro waxqabadka ugu wanaagsan.
Codsiga
Iyada oo ku saleysan mabda'a cabbiraadda gaarka ah, mitirka dareeraha korantada ayaa si gaar ah ugu habboon cabbiraadda dareeraha wax-qabadka ee xaaladaha sida:
Bixinta Biyaha:Cabbiraadda biyaha ceeriin ee gudaha soo gala iyo meelaha laga baxo ee lagu daweeyay socodka biyaha ee maaraynta kheyraadka biyaha.
Daaweynta bulaacadaha: Cabbiraadda bullaacadaha degmada, wasakhda warshadaha, iyo dhoobada leh firfircooni ku filan.
Kiimiko:Cabbiraadda asiidhyada kala duwan, alkali, xalalka milixda, iyo warbaahinta kale ee aadka u daxalaysa iyadoo la adeegsanayo dahaarka u adkaysta daxalka iyo walxaha korantada.
Cabitaanka:Cabbiraadda alaabta ceeriin, dhex-dhexaadinta iyo alaabta dhammaatay inta lagu jiro soo saarista caanaha, casiir, cabitaanka khamriga iyo cabitaannada kale.
Metallurgy:Cabbiraadda qulqulka macdanta, slurry dabada, biyaha dhuxusha ee lagu farsameeyo macdanta oo leh qalab u adkaysta.
Tamarta:Cabbiraadda wareegga biyaha qaboojinta, condensate, dareerayaasha daawaynta kiimikada ee hababka warshadda korontada, iwm.
Shanghai Wangyuanwaxa uu leeyahay waayo aragnimo ka badan 20 sano soo saarista iyo u adeegida qalabka cabbiraadda. Aqoontayada xirfadeed ee ballaaran iyo daraasado kiis oo dhan oo leh dhammaan noocyada mitirka socodka ayaa noo suurtagelinaya inaan bixinno xalalka la socodka socodka oo si sax ah u buuxinaya baahiyahaaga. Haddii ay jiraan wax su'aalo ah iyo baahiyo ku saabsan mitirka socodka korantada, fadlan ha ka waaban inaad nala soo xiriirto.
