Ukunyangwa kwamanzi kunye nokuhanjiswa kwemisebenzi kungqongqo ngokwendalo, kubandakanywa ukuhamba kwamanzi ukusuka kwindawo enye ukuya kwenye, ukunyuka koxinzelelo lokuhluza, ukutofa iikhemikhali zokucoca amanzi, kunye nokuhambisa amanzi acocekileyo kwiindawo zokusetyenziswa. Imitha yokuqukuqela ye-electromagnetic inokuba sisisombululo esisebenzayo sokuqinisekisa ukusebenza okuchanekileyo kwesixhobo ukuqinisekisa ukusebenza okuphezulu kwenkqubo yokudosa imichiza.
Iinkqubo zokutya ezinikezelweyo zisetyenziselwa ukubonelela ngeekhemikhali kuzo zonke izigaba zamanzi kunye nokusebenza kwamanzi amdaka.Inkqubo yokucoca amanzi ifuna ukuhlanganiswa okufanelekileyo, ngoko ke iikhemikhali zingadinga ukufakwa ukuseka indawo efanelekileyo yokukhula kwezinto eziphilayo.Kuyimfuneko kwakhona ukufumana i-alkalinity eyaneleyo yokugcina uluhlu olufunekayo lwe-pH yokusebenza.
Njengenxalenye yenaliti yemichiza, ngokuqhelekileyo kuyimfuneko ukongeza i-asidi okanye i-caustic ukulawula i-pH, ukongeza i-chloride ye-ferric okanye i-alum ukususa izondlo, okanye ukongeza imithombo ye-carbon eyongezelelweyo efana ne-methanol, i-glycine okanye i-acetic acid ekuphuhliseni inkqubo. amazinga okonakala, ukugcinwa rhoqo kwezixhobo, kunye nezinye iziphumo ezibi.
Inkqubo nganye yokutya kweekhemikhali iyahluka, kuxhomekeke kuhlobo lweekhemikhali eziza kuphonswa, ukugxininiswa kwayo, kunye nesantya sokutya esifunekayo.
Kwiimeko ezininzi, ipompo yokulinganisa isetyenziswe kwisityalo sokucoca amanzi sisixhobo esihle sokufuduswa kweekhemikhali zokulinganisa iikhemikhali ezinokutshintsha umthamo ngesandla okanye ngokuzenzekelayo ngokweemfuno zenkqubo yeemeko.Olu hlobo lwempompo lubonelela ngezinga eliphezulu lokuphindaphinda kwaye lunokupompa iindidi zeekhemikhali, kubandakanywa i-acids, i-alkali kunye nezinto ezinobungozi okanye i-viscous liquids kunye ne-slurries.
Izityalo zokucoca amanzi zihlala zifuna iindlela zokwandisa imisebenzi yazo ngokunciphisa ukugcinwa, ixesha lokunciphisa, ukuchithwa kunye neminye imiba.Into nganye ichaphazela ukusebenza kakuhle kunye nokuveliswa kwemveliso.Kodwa xa zidibaniswe, ziya kuchaphazela kakhulu umthamo wemveliso yefektri kunye nezantsi.
Indlela yodwa yokwazi ukujova umlinganiselo ochanekileyo wekhemikhali enikeziweyo kwinkqubo yokucoca amanzi kukumisela umlinganiselo wedosi wangempela ogcinwe yipompo yokulinganisa i-metering.Umngeni kukuba iimpompo ezininzi zokujova iikhemikhali azivumeli umsebenzisi ukuba afowunele kwizicwangciso ezipheleleyo kwizinga elithile ledosi.
Amava abonise ukuba ukusetyenziswa kweemitha zokuhamba ukuqinisekiswa kokusebenza kwempompo kunokubonelela ngolwazi oluxabisekileyo malunga nokusebenza kwempompo kunye nokuchaneka kwenkcazo yomenzi.Ingakwazi kwakhona ukuchonga iingxaki zokusebenza kunye nokunciphisa ukusebenza kakuhle ngenxa yenxalenye yokugqoka okanye ezinye iimeko.Ngokongeza iimitha zokuhamba kunye neevalve phakathi kwempompo kunye nenkqubo, abasebenzisi banokufumana ulwazi lokuvavanya ukusebenza kwempompo yangempela, ukugqamisa nayiphi na imilinganiselo, kwaye ulungelelanise isantya sempompo.
Iindidi ezininzi zeemitha zokuhamba zilinganisa ulwelo, kwaye ezinye zifaneleke ngakumbi kwindawo yokucocwa kwamanzi kunye namanzi amdaka kunezinye.Ezinye iimitha zichanekile kwaye ziyaphinda-phinda kunezinye.Ezinye zifuna ukulungiswa okuncinci okanye okuntsokothileyo, kwaye ezinye zihlala ixesha elide kunezinye.Kubalulekile ukuqwalasela zonke iindlela zokukhetha kwaye ungagxininisi nje kumbandela omnye, onjengexabiso.Xa kuqwalaselwe ukusebenza okufunekayo kunye nemisebenzi yolondolozo, amaxabiso aphantsi okuthenga ahlala esona silahlekisayo se-TC esipheleleyo. ayijongi kuphela ixabiso lokuthenga, kodwa kunye neendleko zofakelo, ukugcinwa, kunye nokutshintshwa kweemitha.
Ukuqwalasela iindleko, ukuchaneka kunye nobomi benkonzo, i-electromagnetic flowmeters ingaba yinto efanelekileyo yokufuna izicelo zonyango lwamanzi.Iteknoloji yokulinganisa i-electromagnetic iphelisa imfuno yeendawo ezihambayo, ezinokubangela imiba yokusebenza kunye nokugcinwa xa isetyenziselwa ulwelo olunomxholo ophezulu. amaxabiso ngexabiso elifanelekileyo.
I-electromagnetic flowmeter isebenza ngokomthetho kaFaraday wokufakelwa kwe-electromagnetic ukulinganisa isantya solwelo.Umthetho uthi xa umqhubi ehamba kwintsimi yamagnetic, isibonakaliso sombane senziwa kwi-conductor, kwaye umqondiso wombane uhambelana nesantya samanzi ahambayo kwintsimi yamagnetic.
Ngokuxhomekeke kumanzi aphakathi kunye / okanye umgangatho wamanzi, i-stainless steel standard (AISI 316) i-electrodes esetyenziswe kwiimitha ezininzi zokuhamba kwe-electromagnetic inokwanela.Nangona kunjalo, ezi electrode zixhomekeke kwimigodi kunye nokuqhekeka kwiindawo ezinobungozi, ezinokubangela ukuchaneka kwe-flowmeter ukuguqula ixesha.Abanye abavelisi bezixhobo baye batshintshela kwi-Hastelloy C ukuya kwi-electrode yokumelana nemigangatho yobomi obungcono kunye ne-electrode yokumelana nemigangatho yobomi obude. ukuchasana okuphezulu kwi-corrosion yendawo, eyinzuzo kwiindawo eziqulethe i-chloride kumaqondo aphezulu aphezulu.Ngenxa ye-chromium kunye nomxholo we-molybdenum, unomgangatho ophezulu wokumelana nokubola kwe-corrosion.I-Chromium yandisa ukuchasana neemeko ze-oxidizing, kwaye i-molybdenum yandisa ukuchasana nokunciphisa indawo.
Abanye abavelisi basebenzisa i-Teflon lining endaweni yerabha eqinile yerabha ukubonelela ngezinto ezinokumelana nobushushu obuphezulu kunye neempawu ezinamandla zekhemikhali.
Inyaniso ibonise ukuba i-electromagnetic flowmeters ifaneleke kakhulu kwizicelo zemichiza ebalulekileyo yenaliti kwiindawo zokunyanga amanzi. Zivumela abaqhubi bezityalo ukuba balinganise ngokuchanekileyo umthamo wolwelo oludlulayo kubo. Ezi mitha zinokusetyenziswa njengenxalenye yenkqubo evaliweyo yokuthumela imveliso kwisilawuli se-logical logic (PLC) ukumisela idosi yemichiza kulo naliphi na ixesha. zenzelwe ukufezekisa ukuchaneka kwe-0.25% phantsi kweemeko ezingaphantsi kweemeko zokuhamba kwamanzi.Ngexesha elifanayo, ukucwangciswa kwetyhubhu evulekileyo engabonakaliyo, evulekileyo iphantse ikhuphe ilahleko yoxinzelelo.Ukuba icaciswe ngokuchanekileyo, imitha ayithinteki kangako yi-viscosity, ubushushu, kunye noxinzelelo, kwaye akukho zixhobo ezihambayo ezithintela ukuhamba, kwaye ukugcinwa kunye nokulungiswa kugcinwa kuncinci.
Kwiindawo ezifunwayo zesityalo sokunyanga amanzi, kwanempompo yokulinganisa i-metering engcono kakhulu inokuhlangabezana neemeko zokusebenza ezihluke kwizinto ezilindelekileyo.Ngokuhamba kwexesha, ukulungiswa kwenkqubo kunokutshintsha ubuninzi, ukuhamba, uxinzelelo, ubushushu, kunye ne-viscosity ye-fluid ekufuneka impompo iphathe.
