Kwindawo yokuvavanywa komgangatho wamanzi, ukuthotyelwa komthetho kubaluleke kakhulu. Ukubeka iliso kunye nokugcina amanqanaba okuqhuba ngendlela efanelekileyo kubalulekile kuluhlu olubanzi lwamashishini, kubandakanya neearhente zendalo, izityalo zokwenza imveliso kunye neelebhu. Ukuqinisekisa imilinganiselo echanekileyo kunye nokubambelela kwimigaqo, iimitha ezinokuthenjwa zidlala indima ebalulekileyo.
Eli thuba le-Blog liya kudla ngokubaluleka kokuthotyelwa komthetho, ukubaluleka kweemitha ezithembekileyo zokuqhutywa, kunye nezinto eziphambili ekufuneka ziqwalaselwe xa ukhetha enye.
Ukuqonda ukuthotyelwa komgaqo:
Iimfuneko zeNtlanganiso zibalulekile kuwo nawuphi na umbutho obandakanyekayo kuvavanyo lwenqanaba lokuphatha kwamanzi. Le migaqo yenzelwe ukukhusela indalo esingqongileyo, kunye nempilo yoluntu, kwaye iqinisekise ukhuseleko lwemithombo yamanzi. Ngokunamathela kwizikhokelo zolawulo, imibutho inokuphepha imiphumo emithetho, ikhusele igama labo, kwaye libe negalelo kwizinto ezizinzileyo.
Iimitha zomsebenzi zokuqhuba zibalulekile ekujongani iiparamitha ezisemgangathweni ezifana ne-sinity, i-TDS (iyonke i-solids), kunye ne-ion yoxinzelelo. Imilinganiselo echanileyo yokulinganisa yenza ukuba imibutho yokuvavanya umgangatho wamanzi uphela, chonga ungcoliseko olunokubakho, kwaye uthathe amanyathelo afanelekileyo ukugcina ukuthotyelwa.
Yintoni imitha yokuqhutywa? Ingaba isebenza kanjani?
Iimitha zokuqhuba iimitha zizixhobo ezisetyenziselwa ukulinganisa ukuqhutywa kombane kwesisombululo okanye kwizinto. Ziqhelekile kwimizi-mveliso eyahlukeneyo, kubandakanya ukuhlolwa kweliso kwindalo, ukuvelisa, kunye neelebhu, ukuvavanya umgangatho kunye nokucoceka kwamanzi, izisombululo zekhemikhali, kunye nezinye izinto zolwelo.
UMGAQO-NKQUBO WOBUCHULE:
Iimitha zokuqhuba zisebenza ngokusekwe kumgaqo wokuba ukwenziwa kombane kunxulumene ngokuthe ngqo noxinzelelo lwee-Ions ezikhoyo kwisisombululo. Xa umbane wangoku udluliselwe kwisisombululo, i-Ions isebenza njengabaphathi kwaye ivumela ukuba ihambe yangoku.
Imitha yokuqhutywa kwemitha isebenzisa lula apho ukuqhubeka khona ngoku ngesisombululo kwaye kubonelela ngokulinganayo ukufundela.
Kwiimitha ezininzi zokuziphatha, ii-electrodes ezimbini okanye ezine zintywiliselwa kwisisombululo. I-electrodes iqhele okwenziwa ngegrafu okanye intsimbi kwaye ikwindawo eyahlukileyo kumgama owaziwayo.
Imitha isebenza ngokutshintshayo phakathi kwe-electroni kwaye inyathelo lokuphosa ivolumo. Ngokubala ukuxhathisa kunye nokusebenzisa izinto ezifanelekileyo zokuguqula, imitha imisela ukuqhubela phambili kombane kwesisombululo.
Ukubaluleka kweemitha ezinokuthenjwa:
Iimitha ezithembekileyo zokuqhutywa zibalulekile zokufunda ngokuchanekileyo nangokungaguqukiyo. Nazi ezinye zezizathu eziphambili zokuba zisebenzise imitha ethembekileyo yokuqokelelwa kubalulekile:

Oku kuchaneka kubalulekile ukuba imibutho yenze izigqibo ezinolwazi kwaye ithathe amanyathelo afanelekileyo ukulungisa naluphi na ukuphambuka kwimigangatho yolawulo.
b. Ukulandelela:
Iimitha ezinokuthenjwa ngeenyawo zihlala ziza nezatifikethi zokulingana kunye neempawu zokulandela. Oku kwenza ukuba imibutho yokubonisa ukuchaneka kunye nokuthembeka kwemilinganiselo yazo ngexesha lophicotho okanye xa iceliwe ngabasemagunyeni.
c. Ukuqina kunye noLongeve:
Ukutyala imali kwimitha ethembekileyo yokuqhutywa kwengqondo iqinisekisa ukuqina kunye nokusebenza kwexesha elide. Iimitha ezinamandla zenzelwe ukumelana neemeko ezinzima zokusingqongileyo, ukusetyenziswa rhoqo, kwaye zibonelele ngokusebenza okungapheliyo ngokuhamba kwexesha. Olu luvo olude lunciphisa imfuneko yokutshintshwa rhoqo kwaye kuncitshiswe ixesha lokuphumla ngexesha lovavanyo.
d. Imveliso ephuculweyo:
Iimitha ezithembekileyo zokuqhutywa zinemitha zihlala zinikezela ngezinto eziphambili, ezifana nokungena kwedatha ezenzekelayo, ukubeka iliso okwethutyana, kunye neenketho zokuqhagamshelwa. Ezi nkqubo zovavanyo lokungena ekungeneni kweenkqubo zokulinganisa, ukunciphisa iimpazamo zezathunzi, kunye nokonyusa imveliso iyonke.
Ngaba imitha yedijithali yedijithali yedijithali yedijithali inceda njani ukuqinisekisa ukuthotyelwa komgaqo?
Ukulinganiselwa kweparamitha echanekileyo
Cwaka's Imitha yedijithali yedijithali, Imodeli DDG-2080S, inikezela ngoluhlu olubanzi lweeparamitha zemilinganiselo, kubandakanya ukwenzeka, ukuxhathisa, ubushushu obunyibilikisiweyo (i-TDS), kunye nobushushu.
Lo msebenzi wokulinganisa obanzi uvumela amashishini ukuba ahlole iiparamitha ezininzi ezibalulekileyo ekumiselweni komgaqo. Inqanaba elichanekileyo lale paramers liqinisekisa ukubambelela kwimigangatho ethile yolawulo kunye nezikhokelo.
Ukujonga ukuthotyelwa kwemizi-mveliso eyahlukeneyo
Imitha yedijithali yedijithali ifumana isicelo kwimizi-mveliso eyahlukeneyo njengezityalo zamandla, iinkqubo zokuxhwalela, ukucofa amanzi, kunye nolawulo lwamanzi olusasazo.
Ngokubonelela ngemilinganiselo echanekileyo nethembekileyo, incedisa lo mveliso ukubeka iliso nokugcina ukuthotyelwa kweemfuno ezithile zomthetho ezifanelekileyo kwimisebenzi yazo. Idlala indima ebalulekileyo ekuqinisekiseni ukuba umgangatho wamanzi asetyenzisiweyo okanye ukhutshiwe unemigangatho emiselweyo.
Ulawulo oluchanekileyo kunye nenkqubo yenkqubo
Nge-MODBUS ROMBUS RTU RORMPOL i-ROMTR48 I-protocol kunye ne-4 ukuya kwi-4-20ma ikhutshiwe, imizi yedijithali yedijithali yenza ukuba iliso libe nokubekwa kweliso kulawulo kunye nobushushu.
Obo buchule buvumela amashishini ukuba asebenzele iinkqubo zabo kwaye aqinisekise ukuba bayasebenza ngaphakathi kwe-ranges evumelekileyo echazwe yimizimba elawulayo. Ngokusebenzisa kakuhle imisebenzi yabo esekwe kwimilinganiselo yexesha elingexesha, amashishini anokunciphisa umngcipheko wokungahambelani nokugcina imigangatho yolawulo rhoqo.
Uluhlu lokulinganisa olubanzi kunye nokuchaneka
Imitha yedijithali yedijithali ibonelela ngemilinganiselo ebanzi yokulinganisa, ityuwa, i-TDS, kunye neqondo lokushisa, ukulungiselela izixhobo ezahlukeneyo zemizi-mveliso. Ukuchaneka kwemitha nge-2% ± 0.5 ℃ iqinisekisa imilinganiselo ethembekileyo kunye negalelo ekuthobeleni iimfuno zolawulo.
Ukufundwa ngokuchanekileyo kwenza ukuba amashishini afumane ukuphambuka okufihlakeleyo kwiiparamitha ezisemgangathweni, ukuqhuba amanyathelo okulungisa ngexesha elifanelekileyo ukugcina ukuthotyelwa.
Yintoni enokwenziwa ziimitha zokuqhuba?
Iimitha zokuqhuba zisetyenziswa ngokubanzi kwizicelo ezahlukeneyo ezinxulumene novavanyo lomgangatho wamanzi. Ezinye zezicelo eziqhelekileyo apho iimitha zokhukuma ziyasetyenziswa zibandakanya:
Ukuhlolwa kwendalo:
