Mtengo wa pH wa madzi ndi chizindikiro chofunikira kwambiri poyesa kuchuluka kwa acidity kapena alkalinity yamadzi am'madzi, ndipo ndi chimodzi mwazinthu zofunika kwambiri pakuwunika momwe madzi alili. Kuchokera pachitetezo chamadzi akumwa kupita kumafakitale komanso kuteteza zachilengedwe, kuwunika kolondola kwa pH ndikofunikira. Sensa yamadzi ya pH ndiye chida chofunikira kwambiri pokwaniritsa muyeso uwu.
I. Makhalidwe a Madzi a pH Sensors
Masensa a pH amadzi amazindikira acidity kapena alkalinity ya yankho lamadzi poyesa kuchuluka kwa ayoni wa haidrojeni (H⁺). Zigawo zake zazikulu ndi ma electrode a membrane wagalasi omwe amakhudzidwa ndi ayoni wa haidrojeni ndi ma elekitirodi. Masensa amakono a pH nthawi zambiri amawonetsa izi:
1. Kulondola Kwambiri ndi Kulondola
- Chiwonetsero: Masensa apamwamba a pH amatha kupereka kulondola kwa ± 0.1 pH kapena kupitilira apo, kuwonetsetsa kudalirika kwa data.
- Ubwino: Amapereka maziko olondola a data pakuwongolera ndondomeko ndi kuyang'anira chilengedwe, kupewa kuwonongeka kwa kapangidwe kapena kuganiziridwa molakwika kwa madzi chifukwa cha zolakwika za muyeso.
2. Kuyankha Mwachangu
- Chiwonetsero: Sensa imachita mwachangu kusintha kwa pH, nthawi zambiri imafikira 95% ya kuwerenga komaliza mkati mwamasekondi mpaka makumi amasekondi.
- Ubwino: Kumathandiza kujambula zenizeni za kusintha kwachangu kwa madzi, kukwaniritsa zofunikira zenizeni za kayendetsedwe ka kayendetsedwe kake ndikuthandizira kusintha kwa nthawi yake.
3. Kukhazikika Kwabwino
- Chiwonetsero: Masensa opangidwa bwino amatha kusunga kuwerengera kokhazikika kwa nthawi yayitali pansi pazikhalidwe zogwira ntchito mosasunthika pang'ono.
- Ubwino: Amachepetsa kufunika kosintha pafupipafupi, amachepetsa kuyesayesa, ndikuwonetsetsa kuti deta ipitilirabe komanso kufananizidwa.
4. Mitundu Yosiyanasiyana ya Kuyika ndi Kugwiritsa Ntchito
- Mbali: Kuti agwirizane ndi zochitika zosiyanasiyana, masensa a pH amabwera m'njira zosiyanasiyana:
- Kalasi ya Laboratory: Zonyamula, zolembera, ndi ma benchtop kuyesa mwachangu kumunda kapena kusanthula kolondola kwa labotale.
- Njira Yapaintaneti: Mitundu yozama, yodutsa, yoyika kuti iwunikire mosalekeza pa intaneti pamapaipi, akasinja, kapena mitsinje.
- Ubwino: Kusinthasintha kwapamwamba kwambiri kwakugwiritsa ntchito, kuphimba pafupifupi zochitika zonse pomwe kuyeza kwa pH kumafunikira.
5. Amafuna Kusamalira Nthawi Zonse ndi Kulinganiza
- Chiwonetsero: Ichi ndiye "choyipa" chachikulu cha masensa a pH. Nembanemba yagalasi imakonda kuwonongeka ndi kuwonongeka, ndipo electrolyte mu electrode yowunikira imachepa. Kuwongolera pafupipafupi ndi mayankho wamba wamba (kuwongolera mfundo ziwiri) ndi kuyeretsa ma elekitirodi ndikofunikira.
- Zindikirani: Kukonza pafupipafupi kumadalira momwe madzi alili (monga madzi otayira, madzi amafuta ambiri amafulumizitsa kuipitsidwa).
6. Nzeru ndi Kuphatikizana
- Chiwonetsero: Masensa amakono a pH pa intaneti nthawi zambiri amaphatikizira masensa a kutentha (kubwezera kutentha) ndikuthandizira zotulutsa digito (monga RS485, Modbus), kulola kulumikizidwa kosavuta kwa PLCs, machitidwe a SCADA, kapena nsanja zamtambo zowunikira kutali ndi kusanthula deta.
- Ubwino: Imathandizira ntchito yomanga makina owunikira okha, ndikupangitsa kuti pakhale ntchito zosayang'aniridwa ndi ma alarm.
II. Zochitika Zazikulu Zogwiritsira Ntchito
Kugwiritsa ntchito masensa a pH ndikofala kwambiri, kumakhudza pafupifupi magawo onse okhudzana ndi madzi.
1. Kusamalira Madzi Owonongeka ndi Kuyang'anira Chitetezo Chachilengedwe
- Malo Oyeretsera Madzi a Municipal/Mafakitale:
- Mfundo Zogwiritsira Ntchito: Malo olowera, potulukira, matanki a biological reaction (ma tank aeration), potulutsira.
- Udindo: Kuwunika kwa pH yolowera kumapereka chenjezo loyambirira la kusokonekera kwamadzi otayidwa m'mafakitale; njira yachilengedwe yochizira imafuna mtundu wa pH woyenerera (nthawi zambiri 6.5-8.5) kuti zitsimikizire zochita za tizilombo tating'onoting'ono; pH yamadzimadzi iyenera kukwaniritsa miyezo isanatulutsidwe.
- Kuyang'anira Madzi Ozungulira:
- Mfundo Zogwiritsira Ntchito: Mitsinje, nyanja, nyanja.
- Ntchito: Kuyang'anira matupi amadzi kuti aonongedwe ndi mvula ya asidi, madzi otayira m'mafakitale, kapena ngalande za migodi ya asidi, ndikuwunika thanzi la chilengedwe.
2. Industrial Process Control
- Makampani a Chemical, Pharmaceutical, Food & Beverage Industries:
- Mfundo Zogwiritsira Ntchito: Ma rectors, akasinja osakaniza, mapaipi, njira zophatikizira zinthu.
- Udindo: pH ndiye gawo lofunikira pamachitidwe ambiri amankhwala, omwe amakhudza mwachindunji momwe amachitira, kuyera kwazinthu, zokolola, komanso chitetezo. Mwachitsanzo, pakupanga mkaka, mowa, ndi zakumwa, pH ndiyofunikira pakuwongolera kukoma ndi moyo wa alumali.
- Boiler ndi Madzi Ozizira:
- Mfundo Zogwiritsira Ntchito: Madzi odyetsa, madzi opopera, madzi ozizira ozizira.
- Udindo: Kuwongolera pH mkati mwamtundu wina (nthawi zambiri zamchere) kuti mupewe dzimbiri ndi makulitsidwe a mapaipi ndi zida zachitsulo, kukulitsa moyo wautumiki ndikuwongolera kutentha.
3. Ulimi ndi Ulimi
- Zam'madzi:
- Malo Ogwiritsira Ntchito: Maiwe a nsomba, akasinja a shrimp, Recirculating Aquaculture Systems (RAS).
- Udindo: Nsomba ndi shrimp zimakhudzidwa kwambiri ndi kusintha kwa pH. Kukwera kwambiri kapena kutsika kwa pH kumakhudza kupuma kwawo, kagayidwe kake, ndi chitetezo chamthupi, ndipo kungayambitse imfa. Kuwunika kosalekeza ndi kukhazikika kumafunika.
- Ulimi wothirira:
- Mfundo Zogwiritsira Ntchito: Magwero a madzi othirira, njira zothirira.
- Ntchito: Madzi amchere kapena amchere amatha kusokoneza kapangidwe ka nthaka ndi feteleza, komanso kuwononga mizu ya mbewu. Kuwunika pH kumathandizira kukhathamiritsa kuchuluka kwa madzi ndi feteleza.
4. Madzi akumwa ndi madzi a Municipal Water
- Mfundo Zogwiritsira Ntchito: Magwero a madzi opangira mankhwala, njira zochizira (monga coagulation-sedimentation), madzi omalizidwa, maukonde a mapaipi a tauni.
- Udindo: Onetsetsani kuti pH ya madzi akumwa ikugwirizana ndi miyezo ya dziko (mwachitsanzo, 6.5-8.5), kukoma kovomerezeka, ndikuwongolera pH kuti muchepetse dzimbiri mumaneti operekera, kuteteza "madzi ofiira" kapena "madzi achikasu" zochitika.
5. Kafukufuku wa Sayansi ndi Ma Laboratories
- Mfundo Zogwiritsira Ntchito: Ma Laboratories m'mayunivesite, mabungwe ofufuza, malo opangira ma R&D, ndi mabungwe oyesa zachilengedwe.
- Ntchito: Kusanthula madzi, kuyesa mankhwala, chikhalidwe chachilengedwe, ndi kafukufuku wasayansi wofuna kudziwa bwino za acidity kapena alkalinity.
Chidule
Sensa yamadzi ya pH ndi chida chowunikira mwaukadaulo koma chofunikira kwambiri. Mawonekedwe ake olondola kwambiri komanso kuyankha mwachangu kumapangitsa kukhala "wotumiza" wa kasamalidwe kabwino ka madzi. Ngakhale zimafunika kukonza nthawi zonse, mtengo wake sungathe kusintha. Kuyambira kuwunika kwa mitsinje poteteza chilengedwe mpaka kuthira madzi akumwa kuonetsetsa chitetezo, kuchokera kumafakitale kupita ku ulimi wamakono wopititsa patsogolo zokolola, masensa a pH amagwira ntchito yofunika kwambiri mwakachetechete, kukhala gawo lofunikira poteteza madzi abwino komanso kuwongolera momwe angapangire.
Titha kuperekanso njira zosiyanasiyana zothetsera
1. M'manja mita kwa Mipikisano parameter madzi khalidwe
2. Dongosolo la Buoy loyandama lamtundu wamadzi wamitundu yambiri
3. Burashi yotsuka yokha yamadzi ambiri amadzimadzi
4. Seti yathunthu ya ma seva ndi pulogalamu yopanda zingwe, imathandizira RS485 GPRS / 4g/WIFI/LORA/LORAWAN
