Ukucocwa kwamanzi kunye nokuhanjiswa kwemisebenzi kungqongqo ngokwendalo, kubandakanya ukuhamba kwamanzi ukusuka kwindawo ukuya kwenye, ukunyuka koxinzelelo lokuhluza, ukutofa iikhemikhali zokucoca amanzi, kunye nokuhambisa amanzi acocekileyo kwiindawo zokusetyenziswa.Ukuchaneka kunye nokuthembeka kubaluleke kakhulu xa usebenzisa ipompo yokulinganisa umthamo olawulwayo. njengenxalenye yenkqubo yokutofa kweekhemikhali kunye neyongezelelweyo kwinkqubo yokucoca amanzi.I-flowmeter ye-electromagnetic ingaba sisisombululo esisebenzayo sokuqinisekisa ukusebenza okuchanekileyo kwezixhobo zokuqinisekisa ubuninzi benkqubo yokudosa imichiza.
Iinkqubo zokutya ezizinikeleyo zisetyenziselwa ukubonelela ngeekhemikhali kuzo zonke izigaba zamanzi kunye nokusebenza kwamanzi amdaka.Inkqubo yokucoca amanzi ifuna i-synthesis efanelekileyo, ngoko ke iikhemikhali zinokudinga ukufakwa ukuseka indawo efanelekileyo yokukhula kwezinto eziphilayo.Kuyimfuneko kwakhona ukufumana i-alkalinity eyaneleyo ukuze gcina uluhlu lwe-pH olufunekayo.
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 ukwenzela uphuhliso lwenkqubo.Xa ufaka imichiza ebiza kakhulu inkqubo yokucoca amanzi, abaqhubi bezityalo kufuneka baqinisekise ukuba izixa ezichanekileyo zongezwa kwinkqubo njengenxalenye yolawulo lomgangatho.Ukusetyenziswa kakhulu okanye kuncinci kakhulu kwemichiza kunokukhokelela kwiindleko eziphezulu zokusebenza, ukunyuka kwamazinga okubola, ukugcinwa rhoqo kwezixhobo, kunye nezinye izinto ezimbi. iziphumo.
Inkqubo nganye yokutya kweekhemikhali iyahluka, kuxhomekeke kuhlobo lweekhemikhali eziza kuphonswa, ukugxininiswa kwayo, kunye nesantya sokutya esiyimfuneko.Iipompo zokulinganisa zingasetyenziswa njengenxalenye yenkqubo yokutofa iikhemikhali kwinkqubo yokucoca amanzi.Oku kudla ngokufumaneka kwi ukusebenza kwamanzi omthombo.Umlinganiselo omncinci wesondlo uya kufuna impompo enemitha enokubonelela ngedosi ethile yeekhemikhali kumjelo owamkelayo.
Kwiimeko ezininzi, ipompo yokulinganisa isetyenziswe kwisityalo sokucoca amanzi sisixhobo esihle sokufuduswa kweekhemikhali zokulinganisa iikhemikhali ezinokutshintsha umthamo ngesandla okanye ngokuzenzekelayo ngokweemfuno zenkqubo iimeko.Olu hlobo lwempompo lubonelela ngenqanaba eliphezulu lokuphindaphinda kwaye lingampompa. iindidi zeekhemikhali, kubandakanywa iiasidi, iialkali kunye nezinto ezidliwayo okanye ulwelo lwe-viscous kunye ne-slurries.
Izityalo zokucocwa kwamanzi zihlala zifuna iindlela zokuphucula imisebenzi yazo ngokunciphisa ukugcinwa, ixesha lokunciphisa, ukuchithwa kunye neminye imiba.Into nganye ichaphazela ukusebenza kakuhle kunye nokuveliswa kwemveliso.Kodwa xa zidibaniswe, ziya kuchaphazela kakhulu amandla okuvelisa imveliso kunye nezantsi.
Indlela yodwa yokwazi ukujova umlinganiselo ochanekileyo wekhemikhali enikeziweyo kwinkqubo yokucoca amanzi kukumisela inqanaba ledosi langempela eligcinwe yipompo yokulinganisa i-metering. izicwangciso zomlinganiselo othile wethamo.
Amava abonise ukuba ukusetyenziswa kweemitha zokuhamba ukuqinisekiswa kokusebenza kwempompo kunokubonelela ngolwazi oluxabisekileyo malunga nokusebenza kwempompo kunye nokuchaneka kweenkcukacha zomenzi.Ingakwazi kwakhona ukuchonga iingxaki zokusebenza kunye nokunciphisa ukusebenza kakuhle ngenxa yokugqoka inxalenye okanye ezinye iimeko.Ngokongeza iimitha zokuhamba kunye iivalve phakathi kwempompo kunye nenkqubo, abasebenzisi banokufumana ulwazi lokuvavanya ukusebenza kwezixhobo zangempela, ukugqamisa naluphi na ukungafani, kunye nokulungelelanisa isantya sempompo xa kufuneka.
Iindidi ezininzi zeemitha zokuhamba zilinganisa ulwelo, kwaye ezinye zifaneleke ngakumbi kwindawo yokucocwa kwamanzi kunye namanzi amdaka kunezinye.Ezinye iimitha zichaneke ngakumbi kwaye ziyaphinda-phinda kunezinye.Ezinye zifuna ukulungiswa okuncinci okanye okuntsokothileyo, kwaye ezinye zihlala ixesha elide kunezinye.Kubalulekile ukuqwalasela zonke iikhrayitheriya zokukhetha kwaye ungagxininisi nje kumbandela omnye, njengexabiso.Ukuqwalasela imisebenzi efunekayo yokusebenza kunye nokugcinwa, amaxabiso aphantsi okuthenga ahlala esalahlekisayo.Umlinganiselo ongcono yindleko epheleleyo yobunini (TCO), eqwalasela kungekuphela nje ixabiso lokuthenga, kodwa kunye neendleko zofakelo, ukugcinwa, kunye nokutshintshwa kweemitha.
Ukuqwalasela iindleko, ukuchaneka kunye nobomi benkonzo, i-electromagnetic flowmeters ingaba lukhetho olufanelekileyo lokufuna izicelo zokucoca amanzi.I-teknoloji yokulinganisa i-electromagnetic iphelisa imfuno yeendawo ezihambayo, ezinokubangela imiba yokusebenza kunye nokugcinwa xa zisetyenziselwa ulwelo olunomxholo ophezulu.I-electromagnetic flowmeter inokulinganisa phantse nayiphi na i-conductive fluid, kubandakanywa inkqubo yamanzi kunye namanzi amdaka.Ezi imitha zibonelela ngokuhla koxinzelelo oluphantsi, umlinganiselo owandisiweyo we-turndown kunye nokuphindaphinda okugqwesileyo.Ziyaziwa ngokubonelela ngemilinganiselo yokuchaneka okuphezulu ngexabiso elifanelekileyo.
I-electromagnetic flowmeter isebenza ngokomthetho kaFaraday wokufakelwa kwe-electromagnetic ukulinganisa isantya solwelo.Umthetho uthi xa umqhubi ehamba kwindawo yamagnetic, umqondiso wombane wenziwa kwi-conductor, kwaye umqondiso wombane ulingana nesantya samanzi. ukuhamba kumhlaba wemagnethi.
Ngokuxhomekeke kumanzi aphakathi kunye/okanye nomgangatho wamanzi, i-electrode yentsimbi esemgangathweni (AISI 316) esetyenziswa kwiimitha ezininzi zokuhamba kwe-electromagnetic inokwanela.Nangona kunjalo, ezi electrode ziphantsi komgodi kunye nokuqhekeka kwiindawo ezidliwayo, ezinokubangela ukuchaneka kombane. i-flowmeter ukutshintsha ngokuhamba kwexesha.Abanye abavelisi bezixhobo baye batshintshela kwi-electrodes ye-Hastelloy C njengezinto eziqhelekileyo zokubonelela ukuxhathisa okungcono kwe-corrosion kunye nobomi benkonzo ende.Le superalloy inokuchasana okuphezulu kwi-corrosion yendawo, eyinzuzo kwiindawo ezine-chloride kwiqondo lokushisa eliphezulu. Ngenxa yomxholo we-chromium kunye ne-molybdenum, inomgangatho ophezulu wokumelana ne-corrosion yonke.
Abanye abavelisi basebenzisa i-Teflon lining endaweni yerabha eqinile yerabha ukubonelela ngezinto ezinokumelana nobushushu obuphezulu kunye neempawu zekhemikhali ezinamandla.
Iinyaniso zibonise ukuba i-electromagnetic flowmeters ifaneleke kakhulu kwizicelo zemichiza ebaluleke kakhulu yokutofa kwizibonelelo zonyango lwamanzi.Zivumela abaqhubi bezityalo ukuba balinganise ngokuchanekileyo umthamo wolwelo oludlula kuzo.Ezi imitha zingasetyenziswa njengenxalenye yenkqubo evaliweyo yokuthumela imveliso. kumlawuli wengqiqo ecwangcisiweyo (PLC) ukugqiba umthamo wemichiza kulo naliphi na ixesha.Olu lwazi lunceda ukulawula iindleko zemichiza kunye nokusombulula imimiselo esebenzayo yokusingqongileyo.Bakwabonelela ngeenzuzo zomjikelo wobomi obalulekileyo kunyango lwamanzi kunye nezibonelelo zokuhambisa.Ziyilelwe ukufikelela + 0.25% ukuchaneka phantsi kweemeko zokuhamba kwamanzi angaphantsi kweemeko ezifanelekileyo zokuhamba kwamanzi. Ngexesha elifanayo, i-non-invasive, ukulungelelaniswa kwetyhubhu evulekileyo evulekileyo phantse kuphelisa ukulahlekelwa kwengcinezelo.Ukuba icaciswe ngokuchanekileyo, imitha ayithinteki kakhulu yi-viscosity, ubushushu kunye noxinzelelo, kwaye kukho azikho iindawo ezihambayo ezithintela ukuhamba, kwaye ukugcinwa nokulungiswa kugcinwa kuncinci.
Kwindawo efunwayo yesityalo sokucoca amanzi, kwanempompo yokulinganisa ubungakanani obungcono kakhulu inokuhlangabezana neemeko zokusebenza ezihluke kwizinto ezilindelweyo.Ngokuhamba kwexesha, uhlengahlengiso lwenkqubo lunokutshintsha ukuxinana, ukuhamba, uxinzelelo, ubushushu, kunye ne-viscosity yolwelo olumele luphathwe yimpompo. .
