Ubwino Wosatsutsika wa Mamita a Madzi a Magetsi

Choyamba, mita yamadzi yamagetsi imapereka kulondola kosayerekezeka, ngakhale pamitundu yosiyanasiyana ya kayendedwe ka madzi. Mosiyana ndi mita yamagetsi, yomwe imadalira zinthu zosuntha (monga ma impeller kapena ma piston) zomwe zimatha kuwonongeka pakapita nthawi, mita ya EM ilibe zigawo zamkati zamakina zomwe zimakhudzana ndi madzi oyenda. Kusowa kwa kukangana kapena kuwonongeka kwa makina kumatanthauza kuti kulondola kwawo kumakhalabe kofanana kwa zaka zambiri - nthawi zambiri kumakhala kolondola mkati mwa ± 0.2% mpaka ± 1% ya kuchuluka kwenikweni kwa madzi, kutengera mtunduwo. Amachita bwino kwambiri posamalira kuchuluka kwa madzi okwera komanso otsika: mita yamagetsi nthawi zambiri imavutika ndi kuyenda kochepa (zomwe zimapangitsa kuti madzi asawerengedwe) kapena kuyenda kwakukulu (kuika pachiwopsezo kuwonongeka), koma mita ya EM imasintha mosavuta, kuonetsetsa kuti palibe kugwiritsa ntchito madzi komwe sikulembedwa. Kulondola kumeneku n'kofunika kwambiri kwa makampani omwe cholinga chake ndi kuchepetsa kutayika kwa ndalama kuchokera kumadzi osawerengedwa komanso m'mafakitale omwe amafuna kuwongolera bwino kayendedwe ka madzi kuti akonze njira.

Ubwino wina wodziwika bwino ndikugwirizana kwawo ndi mitundu yosiyanasiyana ya madzi ndi zinthu zina. Mamita achikhalidwe amatha kutsekeka kapena kuwonongeka mosavuta ndi madzi okhala ndi zinyalala, zinthu zolimba zopachikidwa, kapena madzi okhuthala—omwe amapezeka m'mafakitale monga kukonza madzi otayidwa, migodi, kapena kukonza chakudya. Komabe, mamita amagetsi ali ndi chubu chosalala, chosatsekedwa (chomwe nthawi zambiri chimapangidwa ndi zinthu zosagwira dzimbiri monga chitsulo chosapanga dzimbiri kapena chitsulo cha kaboni chokhala ndi PTFE). Kapangidwe kameneka kamawathandiza kuti azitha kugwira madzi okhala ndi matope ambiri, tinthu tating'onoting'ono, kapena mankhwala popanda kutsekeka kapena kusokoneza magwiridwe antchito. Amagwiranso ntchito bwino ndi madzi osayendetsa magetsi akaphatikizidwa ndi ma liners oyenera, kukulitsa ntchito yawo kuposa madzi okha kupita ku madzi ena a mafakitale. Kwa machitidwe a m'matauni omwe amagwira ntchito zosiyanasiyana zamadzi kapena malo opangira madzi omwe ali ndi madzi ochulukirapo, kusinthasintha kumeneku kumathetsa kufunikira kosintha kapena kukonza mita pafupipafupi.

Zofunikira zochepa pakukonza ndi nthawi yayitali yogwira ntchito zimalimbitsa kukongola kwa mita yamadzi yamagetsi. Mita yamakina imafuna kusamalidwa nthawi zonse: zida zosuntha zimafuna mafuta, matope amasonkhana, ndipo zida zosweka (monga ma gasket kapena ma impeller) zimafunika kusinthidwa kuti zisunge kulondola. Ntchitozi sizimangobweretsa ndalama zogwirira ntchito ndi zinthu zokha komanso zimapangitsa kuti nthawi yokonza isagwire ntchito. Mosiyana ndi zimenezi, mita ya EM siili ndi zida zosunthira kuti zigwiritsidwe ntchito. Kukonza nthawi zonse nthawi zambiri kumafuna kuwunikira nthawi ndi nthawi (kochepa kwambiri kuposa kukonzanso mita yamakina) ndikuwunikanso bwino chubu choyendera ndi masensa. Izi zikutanthauza kuti ndalama zogwirira ntchito ndi mabizinesi zimachepa kwambiri—zamagetsi ndi mabizinesi zimasunga ndalama zokonzera, zimachepetsa kusokonekera kwa ntchito, ndikuwonjezera moyo wa mita kufika zaka 10-20, poyerekeza ndi zaka 5-8 pazinthu zina zambiri zamakina.

Ma electromagnetic water meter amaperekanso kuphatikiza deta kwapamwamba komanso luso loyang'anira mwanzeru, mogwirizana ndi kusintha kwa ma network amadzi anzeru. Ma EM meter ambiri amakono ali ndi zotulutsa za digito (monga RS485, Modbus, kapena LoRaWAN) zomwe zimathandiza kulumikizana bwino ndi makina oyang'anira pakati, nsanja za SCADA (Supervisory Control and Data Acquisition), kapena pulogalamu yoyendetsera madzi yochokera mumtambo. Izi zimathandiza kutsata kuchuluka kwa madzi nthawi yeniyeni, kusonkhanitsa deta patali, ndi machenjezo odziyimira pawokha a zolakwika (monga kukwera kwadzidzidzi kwa madzi kapena kugwa, komwe kungasonyeze kutayikira kapena kulephera kwa zida). Mosiyana ndi ma mechanical meter, omwe amafunika kuwerenga pamanja (njira yotenga nthawi komanso yolakwika), ma EM meter amathandiza mabungwe ogwiritsira ntchito kusonkhanitsa deta yolondola, yeniyeni popanda kutumiza antchito kumalo omwe alipo. Izi sizimangowonjezera magwiridwe antchito komanso zimathandizira kuyang'anira madzi mwachangu—mwachitsanzo, kuzindikira ndikuthana ndi kutayikira koyambirira kuti muchepetse zinyalala zamadzi ndi kuwonongeka kwa zomangamanga.

Pomaliza, ma electromagnetic water meter amathandiza kuti mphamvu zigwire bwino ntchito komanso kuti chilengedwe chikhale cholimba. Ma meter a makina amadalira mphamvu ya madzi oyenda kuti atembenuze ziwalo zawo zoyenda, zomwe zimapangitsa kuti mphamvu zichepetse pang'ono koma zoyezeka m'madzi. Pakapita nthawi, kutsika kwa mphamvu kumeneku kumakakamiza mapampu amadzi kugwira ntchito molimbika, zomwe zimawonjezera kugwiritsa ntchito mphamvu. Ma EM meter, omwe ali ndi kapangidwe kake kosalephereka, sapanga kutayika kwa mphamvu. Izi zimachepetsa kufunikira kwa mphamvu pamakina ogawa madzi, kuchepetsa kutsika kwa mpweya ndi ndalama zamagetsi pamagetsi. Kuphatikiza apo, moyo wawo wautali wautumiki komanso kufunikira kochepa kosintha zinthu kumachepetsa kuwononga chilengedwe komwe kumachitika popanga ndi kutaya ma meter akale—kugwirizana ndi khama lapadziko lonse lapansi lolimbikitsa kasamalidwe ka zinthu kosatha.

Pomaliza, mita yamadzi yamagetsi ikuyimira kupita patsogolo kwakukulu paukadaulo woyezera madzi. Kuphatikiza kwawo kulondola kwapadera, kusinthasintha kwapadera pamikhalidwe yovuta, zosowa zosakonzedwa bwino, kuphatikiza mwanzeru kuyang'anira, komanso kugwiritsa ntchito bwino mphamvu kumathetsa mavuto akuluakulu a kasamalidwe ka madzi amakono. Kwa makampani amagetsi, mafakitale, ndi mabungwe amalonda omwe akufuna njira yodalirika, yotsika mtengo, komanso yotetezeka mtsogolo, mita yamadzi yamagetsi ndi chida chofunikira kwambiri pakukonza kagwiritsidwe ntchito ka madzi, kuchepetsa zinyalala, ndikumanga machitidwe amadzi okhazikika.
