Kuyika Chiyeso cha Ma Ultrasonic Flow Meter | Thandizo laukadaulo la Kuyeza Mapaipi Aakulu

Mfundo Zazikulu

A. Kukhazikitsa mapaipi otentha: Kukhazikitsa pa intaneti popanda kutseka mapaipi, koyenera mapaipi akuluakulu osasokonezeka

B. Kuphimba mapaipi ambiri: Thandizani mapaipi a DN65‑DN6000, agwirizane ndi chitsulo cha kaboni, chitsulo choponyedwa, mapaipi a PE, PVC ndi konkire.

C. Kutsika kwa mpweya woipa: Palibe zinthu zosuntha mkati mwa payipi, palibe kukana kowonjezera kwa madzi

D. Kusinthasintha kwa kutentha kwakukulu: Chosinthira kutentha kwambiri chimathandizira kutentha kwapakati kuyambira ‑35℃ mpaka 150℃

E. Kulemba deta yomangidwa mkati ndi njira yoyezera kutentha: Lembani deta yakale yoyendera; thandizirani kuwerengera mphamvu ya kutentha ndi masensa a PT1000

Kulankhulana kwa F. RS485 Modbus-RTU: Kulumikizana kosavuta ndi makina owunikira akutali a DMA, NRW ndi SCADA

1. Mfundo Yogwirira Ntchito & Ubwino Wapakati pa Mapaipi Aakuluakulu

Ma ultrasound flow mita oikamo amagwiritsa ntchito mfundo yoyezera nthawi yodutsa. Masensa amaikidwa mkati mwa payipi kudzera mu zolumikizira zotentha ndipo amalumikizana mwachindunji ndi madzi oyezedwawo. Mosiyana ndi ma clamp-on omwe amatumiza zizindikiro za ultrasonic kudzera m'makoma a mapaipi, ma insertion probes amajambula zizindikiro za liwiro la kuyenda kwa madzi mkati mwa payipi, zomwe zimachepetsa kwambiri kusokoneza kwa zinthu za payipi, dzimbiri ndi kukula kwa mkati.

Chida ichi chimathandizira mapaipi a mainchesi kuyambira DN65 mpaka DN6000, omwe amaphimba chitsulo cha kaboni, chitsulo chosapanga dzimbiri, chitsulo chopangidwa ndi chitsulo, mapaipi a PE, PVC ndi konkire. Chokhala ndi cholumikizira cha ball-valve, probe imatha kuyikidwa kapena kubwezedwa pansi pa mphamvu yonse yogwira ntchito.popanda kuletsa kuyenda kwa mapaipi. Ntchito yokhazikitsa iyi ndi yofunika kwambiri pa mapaipi akuluakulu omwe sangatsekedwe, monga maukonde ogawa madzi m'matauni, mizere yotumizira madzi osaphika komanso mapaipi akuluakulu othirira ulimi.

Palibe zida zoyendera mkati mwa chitolirochi, zomwe zimapangitsa kuti mphamvu ya mpweya isatsike kwambiri ndipo zimachepetsa ntchito yokonza kwa nthawi yayitali. Chosinthira kutentha kwambiri chimatha kugwira ntchito kutentha kwapakati kuyambira ‑35°C mpaka 150°C, kusintha madzi otentha, madzi ozizira ndi madzi osiyanasiyana opangira mafakitale. Chimasunganso ntchito yoyezera kutentha ikaphatikizidwa ndi masensa a kutentha a PT1000 kuti azitha kuwerengera kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito mu HVAC ndi makina opangira magetsi.

Gome 1: Mafotokozedwe Aukadaulo Aakulu

2. Malangizo Okhazikitsa Pamalo Omwe Ali & Kugwira Ntchito Potentha

Kukhazikitsa kolondola kumatsimikiza mwachindunji kulondola kwa kuyeza. Kukhazikitsa kosayenera ndiye chifukwa chachikulu cha kusiyana kwa muyeso. Pewani malo oyika pafupi ndi magwero a turbulence monga mapampu, zigongono, zochepetsera ndi ma valve owongolera. Pazochitika zonse, sungani chitoliro cholunjika cha 10D pamwamba pa mtsinje ndi 5D pansi pa mtsinje. Pa malo omwe ali kumbuyo kwa mapampu kapena zigongono zakuthwa, tambasulani chitoliro cholunjika chakumtunda mpaka 15D. Musayike pamwamba pa chitoliro chokhala ndi mpweya wochuluka kapena pansi pa chitoliro chokhala ndi matope. Sungani malo okwanira obowolera ndi kuchotsa probe pambuyo pake.

Njira yokhazikika yogwiritsira ntchito hot-tapping:

1. Chotsani pamwamba pa chitoliro chakunja → 2. Ikani maziko a chishalo ndi valavu ya mpira wodzaza ndi chibowo → 3. Kuboola kokwanira kolamulidwa ndi kupanikizika → 4. Kuchotsa chobowola, kutseka valavu ndikuchita mayeso otayikira → 5. Ikani chobowola ndikusintha kuya kwa cholowetsa → 6. Konzani njira ya chobowola ndikulimbitsa nati yotsekera → 7. Kulumikiza mawaya kwathunthu ndi chitetezo chosalowa madzi.

Ma waya olumikizira panja ayenera kukhala ndi mulingo wosalowa madzi wa IP67-IP68 kuti apewe kuwonongeka kwa chinyezi.

3. Kukhazikitsa Ma Parameter ndi Kukhazikitsa Kulankhulana

Mukayika makina, malizitsani kuyika magawo pa chosinthira madzi cha TF1100‑EI. Kuchuluka kwa payipi yolakwika kudzabweretsa cholakwika chachikulu cha madzi oyenda. Ogwiritsa ntchito ayenera kudzaza payipi yeniyeni yamkati, makulidwe a khoma, zinthu za payipi ndi zambiri zapakati.

Kuti mutumize deta kutali, konzani magawo a RS485 Modbus RTU kuphatikiza adilesi ya chipangizo, kuchuluka kwa baud ndi kuwunikira parity. Imathandizira kukweza deta ku DMA non-revenue water management system kapena nsanja ya mafakitale ya SCADA. Ntchito yolemba deta yomangidwa mkati imasunga deta yakale kuti iwunikidwe.

Mukamaliza kukonza, onetsetsani kuti payipi yadzazidwa ndi madzi okwanira ndipo yang'anani mphamvu ya chizindikiro pa sikirini ya LCD. Chizindikiro chokhazikika chimayimira momwe chimayikidwira bwino. Chizindikiro chochepa nthawi zambiri chimasonyeza kuya kolakwika kwa choyikira, kuipitsidwa kwa probe kapena kulephera kwa kulumikizana kwa chingwe.

4. Malangizo Osamalira Mosamala Nthawi Zonse

Kuchuluka kwa nthawi yosamalira kumadalira pa malo oyezera. Pa madzi oyera a pampopi, yang'anani momwe chizindikirocho chikugwirira ntchito miyezi 6-12 iliyonse. Pa zimbudzi ndi madzi okhala ndi zinthu zolimba zopachikidwa, fupikitsani nthawi yowunikira kufika miyezi 3-6.

Pokhala ndi kapangidwe ka ballval, probe ikhoza kutulutsidwa pansi pa mphamvu yogwira ntchito popanda kutsekedwa kwa payipi kuti iyeretse ma scaling ndi sediment. Chonde pewani kukanda pamwamba pa ultrasound sensing. Chitani kutsimikizira kwa zero point kamodzi pachaka. Chitani kuyerekezera kwa munda ngati pali kusiyana koonekeratu kwa muyeso.

5. Kuthetsa Mavuto Ofala Pamunda

Chochitika Cholakwika	Chifukwa Chotheka	Yankho Loperekedwa
Mphamvu yochepa ya chizindikiro cha ultrasound	Kuipitsidwa kwa pamwamba pa kafukufuku; chingwe chotayirira kapena cholowa m'madzi	Yeretsani chofufuzira; yang'anani kulumikizana kwa chingwe ndi momwe madzi amagwirira ntchito
Kuwerengera kwa kuyenda kothamanga mwamphamvu	Kuyenda kosokonezeka, thovu lochuluka, kusokoneza kwa maginito	Konzani bwino malo oikira; siyanitsani chingwe cha chizindikiro ndi chingwe chamagetsi amphamvu; sinthani nthaka
Kutulutsa kosasunthika kwa zero	Chitoliro sichinadzazidwe mokwanira; malo olakwika a probe; magawo olakwika a chitoliro	Onetsetsani kuti chitoliro chili bwino mokwanira; sinthani njira yofufuzira; onaninso makonda a m'mimba mwake wa chitoliro

6. Zochitika Zachizolowezi Zogwiritsira Ntchito Makampani

Ma flow mita ogwiritsira ntchito ma ultrasound amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana.

• Kupereka madzi kwa boma: Kuyeza kwa chigawo cha DMA ndi kuyang'anira madzi osagwiritsa ntchito ndalama pa mapaipi akuluakulu, sikufunika kudula mapaipi.
• Malo oyeretsera madzi otayira: Kuwunika momwe madzi amalowera ndi kutuluka kwa madzi amayendera pa ntchito ya zinyalala.
• Ulimi wothirira: Kuyeza kuchuluka kwa madzi m'mapaipi akuluakulu kuti athandize kasamalidwe kosunga madzi.
• Mphamvu, petrochemical ndi zitsulo: Kuwunika momwe madzi ozizira amayendera kuti aone momwe mphamvu zimagwiritsidwira ntchito.

Sensa ya njira imodzi ndi yoyenera pazochitika zonse zowunikira. Sankhani makonzedwe olondola kwambiri kuti muyese kusamutsa deta, ndi probe yotentha kwambiri kuti mugwiritse ntchito kutentha kwapakati.
