Ukusetyenziswa kwe-Electromagnetic Flowmeter kuShishino lwamaPhepha
2022-04-24
Ishishini lephepha lanamhlanje liyinkunzi, itekhnoloji, kunye neshishini elithatha amandla amakhulu kunye nemveliso enkulu. Ineempawu zokuqhubekeka kwemveliso eyomeleleyo, ukuhamba kwenkqubo entsonkothileyo, ukusetyenziswa kwamandla aphezulu, umthamo omkhulu wokulungisa izinto ezikrwada, umthwalo onzima wongcoliseko kunye notyalo-mali olukhulu.
Ii-flowmeters ze-Electromagnetic zithatha indawo ephambili kwishishini lephepha. Esona sizathu sikukuba umlinganiselo we-electromagnetic flowmeter awuchatshazelwa kukuxinana, ubushushu, uxinzelelo, i-viscosity, inombolo yeReynolds kunye notshintsho lwe-conductivity yolwelo ngaphakathi koluhlu oluthile; uluhlu lwalo lokulinganisa lukhulu kakhulu kwaye lunokugubungela zombini isiphithiphithi kunye nokuhamba kwe-laminar. Ukuhanjiswa kwesantya, esingahambelaniyo nezinye iimitha zokuhamba. Ngenxa yesakhiwo esilula se-electromagnetic flowmeter, akukho zixhobo ezihambayo, iindawo eziphazamisayo kunye neendawo eziphazamisayo ezithintela ukuhamba komgangatho olinganisiweyo, kwaye akuyi kubakho iingxaki ezifana nokuvala umbhobho kunye nokugqoka. Inokugcina kakhulu ukusetyenziswa kwamandla kwaye ilawule ngokungqongqo ukukhutshwa kwezinto ezingcolisa indalo.
Ingcebiso yokukhetha imodeli yemitha yombane yombane.
1. Umgca
Umlinganiselo olinganisiweyo kwinkqubo yokwenza iphepha uneempawu zokushisa okuphezulu kunye noxinzelelo oluphezulu, kwaye unomlinganiselo omkhulu weekhemikhali, eziphazamisayo. Ke ngoko, i-electromagnetic flowmeters zonke zifakwe kwi-PTFE yokumelana nobushushu obuphezulu. Nangona umgca we-PTFE uxhathisa kubushushu obuphezulu, awuxhathisi kuxinzelelo olubi. Kwezinye iindawo ezikhethekileyo, ezifana ne-outlet ye-medium-concentration riser, kungekhona nje i-concentration medium high, iqondo lokushisa liphezulu, kodwa kunye ne-vacuum phenomenon iya kwenzeka ngezikhathi ezithile. Kule meko, kuyimfuneko ukukhetha umgca we-PFA.
2. Ii-Electrodes
Ukukhethwa kwee-electromagnetic flowmeter electrode kushishino lwephepha ikakhulu kuthathela ingqalelo imiba emibini: enye kukungatyaleki; enye i-anti-scaling.
Inani elikhulu lamachiza liya kongezwa kwinkqubo yokwenza iphepha, njenge-NaOH, i-Na2SiO3, i-H2SO4, i-H2O2 egxininiswe, njl njl. Kufuneka kukhethwe i-electrode ezahlukeneyo kwiikhemikhali ezahlukeneyo. Ngokomzekelo, i-electrodes ye-tantalum kufuneka isetyenziswe kwi-electric acid dielectric electrode, i-electrodes ye-titanium isetyenziswa ngokubanzi kumajelo e-alkaline, kunye ne-316L i-electrode yensimbi engenasici ingasetyenziselwa ukulinganisa okuqhelekileyo kwamanzi.
Kuyilo lwe-anti-fouling yee-electrodes, i-electrodes engqukuva inokukhethwa kwindawo ephakathi ikakhulu eyenziwe ngezinto ezinobumba kwiqondo eliqhelekileyo lokungcolisa. I-electrode ye-spherical inendawo enkulu yoqhagamshelwano kunye ne-medium medium kwaye ayigqunywanga lula ngezinto ze-fibrous.
