Ulawulo
I-sensor ye-pH egcinwa iphila emanzini amdaka ane-asidi enamandla kufuneka icocwe rhoqo, ilinganiswe ngokuchanekileyo kwiindawo ezintathu, kwaye isebenzise ii-electrode ezihlanganisiweyo ezine-impedance ephezulu. Ukunyamekela okufanelekileyo kuqinisekisa ukuba i-sensor igcina ukuchaneka kwayo kwe-pH ye-0.02 kunye nesisombululo se-pH se-0.01 nokuba kujikeleze i-pH eyi-0 ukuya kwi-14. Abaqhubi banokuthintela ukwakheka kwesikali seeminerali kwaye basebenzise ukucubungula okunamandla kwesignali ukugcina amandla e-electrochemical ekukhukulisekeni, ukuqinisekisa ukuba inkqubo yokungashukumi kweekhemikhali iya kuhlala ixesha elide.
Kutheni Amanzi Amdaka Ane-Acid Enamandla Ebangela Iingxaki Kwizinzwa ze-pH
Kwihlabathi lonyango lwamanzi amdaka kwimizi-mveliso, iindawo ezine-asidi lolona vavanyo lokunyamezela olupheleleyo lokusetyenziswa kwezixhobo. Ukuqinisekisa ukuthembeka kwedatha, kufuneka sijongane nomonakalo obangelwa ziisensa zomzimba neze-electrochemical ezi ndawo.
1. Ukugqwala kwezindlu ngamakhemikhali
Iiasidi ezinamandla zinokonakalisa ngokukhawuleza izinto zokuhlala ezingomelelanga, nto leyo ekhokelela ekungasebenzi kakuhle kwecandelo langaphakathi. Umgca wethu wokuqala wokuzikhusela kukwakhiwa komzimba kwesensor. Ukusebenzisa izindlu ze-ABS ezikumgangatho ophezulu kubonelela ngokumelana kweekhemikhali okufunekayo ukumelana nemisinga yenkunkuma enamandla. Idityaniswe nenqanaba lokhuseleko lwe-IP68, isensor ihlala ivalwe ngokuqinileyo ekungeneni kolwelo olubolayo, nokuba ingaphantsi kwamanzi ngokupheleleyo.
2. I-Electrochemical Potential kunye ne-Electrode Drift
Iindawo ezingqonge iasidi zihlala zibangela "ukushukuma kwe-electrode," apho ukufundwa kwesiseko kutshintsha kuba i-membrane igugile okanye kukho ukungcola kwindawo yokuhlangana. Akukho lwakhiwo oluzinzileyo kakhulu - izinga lokushukuma ≤ 0.02 pH/24h - ulawulo lwenkqubo luba yinto eshukumayo, nto leyo ekhokelela ekulinganisweni kweekhemikhali okungasebenzi kakuhle kunye nokungathobeli imithetho.
Inkqubo yokulungisa inyathelo ngenyathelo kwimeko ye-asidi
Eyona ndlela ikuphela kwayo yokuba nelo nqanaba lokuchaneka kwesixhobo esibaluleke kangaka sokujonga izinto zoshishino kukunamathela kwishedyuli yokulungisa ecwangcisiweyo.
- Ukucoca kunye nokususa ulusu:Susa isensa rhoqo ukuze uhlole ukuba akukho zimbiwa okanye iidiphozithi ezibolayo. Kuba le sensa inemigangatho eqhelekileyoImisonto ye-G3/4, ingasuswa lula kwiifayibha zemibhobho yemizi-mveliso ukuze ihlolwe ngokukhawuleza. Sebenzisa ilaphu elithambileyo okanye isisombululo sokucoca esixutyiweyo esijolise ekuqokeleleni kwezimbiwa ezithile ngaphandle kokugutyungelwa kwenwebu yeglasi.
- Ukulinganisa iiNqanaba eziThathu:Ukulinganisa kufuneka kwenziwe kusetyenziswa indlela ye-three-point ukugcina ulungelelwano kwi-spectrum epheleleyo. Sebenzisa ii-buffers eziqhelekileyo kwii-pH 4.0, i-pH 6.86, kunye ne-pH 9.18Oku kuqinisekisa ukuba i-sensor ichanekile kwiindawo ezine-asidi, ezingathathi cala, kunye ne-alkaline encinci ezidla ngokudibana nazo ngexesha lokuthomalalisa.
- Uhlolo loBulungisa beCable:Jonga iintambo ezikumgangatho ophezulu nezingenangxolo ingako ukuze ubone iimpawu zokonakala kwe-asidi okanye ukubhitya. Nangona ezi ntambo zenzelwe ukuthembeka kwesignali xa zibaleka ngaphezulu kweemitha ezingama-20 (kunye nokuya kuthi ga kwi-1000m nge-RS485), ukuqhekeka kwejakethi kunokubangela ingxolo yombane.
- Ukuqinisekiswa kozinzo lweSignali:Sebenzisa i-RS485 MODBUS yakho okanye i-4-20mA output ukujonga uzinzo. Phantsi kweemeko zokusebenza eziqhelekileyo, kufuneka ulindele uzinzo lwe-≤0.02pH kwixesha leeyure ezingama-24.

Iingcebiso zoBuchule bokuzinza okuphuculweyo: Imbono yoNjineli
Kwiimvavanyo zethu zelebhu kunye novavanyo lomgangatho wokwenziwa, sifumanise ukuba uyilo lwangaphakathi lwesensor lubaluleke kakhulu njengeqokobhe layo langaphandle.
- Ukulwa "neNgxoxo" yoMbane:Sidibaniseukucoca i-axial capacitancekunyeIsithinteli sangaphakathi se-100Mngokukodwa ukuze zisebenze ngcono kunee-electrode eziqhelekileyo kwiindawo ezinengxolo ephezulu ye-VFD (Variable Frequency Drive). Oku kunciphisa kakhulu "incoko" yedatha, ekuvumela ukuba ubone xa isensa ifuna ukucocwa xa ijonga nje ukuphazamiseka kombane okuvela kwiimpompo ezikufutshane.
- Ubude obuqhutywa yiYilo:Qaphela uphuculo loyilo "Ngaphambi vs. Emva" kwisizukulwana sethu samva nje.yandisile icandelo lokucubungula isignali(ubude obupheleleyo yi-205mm). Olu tshintsho luvumela i-sensor ukuba ifakwe kwiindawo ezincinci ngelixa igcina iindawo zokungena ze-elektroniki ezibuthathaka kunye neentambo kude kakhulu nendawo enobungozi ye-asidi. Oku kwandisa ngokufanelekileyo i-Mean Time Between Failure (MTBF) ngokukhusela iindawo ezisengozini kakhulu zendibano kwi-turbulent, high-acid flows.
- Ukhuseleko lokuGqibela njengoLondolozo:Iimpawu zethu zesensorukuya kuthi ga kwii-isolation ezine ezine-3000V protection gradeNgokwembono yolondolozo, oku kusindisa ubomi—kuthintela i-sensor ekubeni “iqhotswe” ngenxa yokunyuka okukhulu kombane okuxhaphakileyo kwizikhululo zokupompa zemizi-mveliso, nto leyo enciphisa ukutshintshwa okungacwangciswanga.
Ukuphunyezwa kunye nokuhlanganiswa kweNkqubo
Le sensor yenzelwe i-"Smart Factory" yanamhlanje kunye nokujonga okukude, inika uqhagamshelo oluguquguqukayo:
- Ukuthembeka Ngeentambo:I-RS485 (iprotocol ye-MODBUS), inokuxhasa ubude belothe obufikelela kwi-1000m, ifanelekile kwisityalo esikhulu sonyango.
- Ukuguquguquka okungenazingcingo:I-4G, i-GPRS kunye ne-LoRaWAN zihambelana ngokupheleleyo nezilumkiso zokugcinwa kwexesha langempela ezithunyelwa ngqo kwiqonga eliphakathi lelifu ngaphandle kwesidingo sokuhlolwa kwesiza rhoqo.
Isiphelo
Musa ukuvumela i-asidi itye ulwazi lwakho. Sebenzisa izinto eziqinileyo ezifana ne-ABS housing kunye ne-high-impedance interiors kunye nokugcinwa okusebenzayo kunye nekhalenda yamanqaku amathathu ukuqinisekisa ukuba amanzi akho amdaka emizi-mveliso ajongwa ngokufanelekileyo, rhoqo, kwaye ngaphandle kokuchitha imali eninzi.
