Lefoo Isilinganisi Sokungeleza Sikagesi Nobuzibuthe

Izicelo Ezibanzi Zemitha Yokugeleza Kagesi yakwaLefoo

Ama-electromagnetic flowmeter akwaLefoo anikeza izinzuzo ezinkulu kuzo zonke izinhlelo zokusebenza ezehlukene, futhi izinsimbi ezinobubanzi obukhulu zisetshenziswa kakhulu emisebenzini yokunikezela amanzi nokuthuthwa kwamanzi angcolile; izinsimbi ezinobubanzi obuphakathi nobuncane zivame ukusetshenziswa ezimeni ezidinga izinga eliphezulu noma okunzima ukukala, njengokulawulwa kwamanzi okupholisa imbobo yesithando somoya emsebenzini wensimbi, ukukalwa kwenhlama nephepha emsebenzini wephepha, kanye nemisebenzi yamakhemikhali. Uketshezi olugqwalisa kakhulu, inhlama yensimbi emsebenzini wezinsimbi ezingenayo insimbi; izinsimbi ezinobubanzi obuncane kakhulu nezincanyana zivame ukusetshenziswa ezindaweni ezidinga inhlanzeko njengomkhakha wemithi, wokudla, kanye ne-biochemistry.

Izici Zemitha Yokugeleza Kagesi yakwaLefoo

1. Ukunemba Okungaguquki Kuzo Zonke Izimo: Ama-electromagnetic flowmeter akwaLefoo aletha izilinganiso ezinembile ezingathintwa yizinguquko zokuminyana koketshezi, ukuqina, izinga lokushisa, umfutho, noma ukuqhuba—okuqinisekisa ukusebenza okuqhubekayo ezindaweni eziyinkimbinkimbi.

2. Idizayini Engaphazamisi, Akukho Ukulahleka Komfutho:Njengoba kungenazo izingxenye ezivimbayo ngaphakathi kweshubhu yokulinganisa,Lefooama-flowmeter agwema ukulahleka komfutho okwengeziwe futhi anciphise izidingo zepayipi eliqondile, okwenza ukuthi akwazi ukuzivumelanisa kahle nezicelo zokulinganisa inhlama.

3. Izinto Eziqinile Zokusetshenziswa Kwesikhathi Eside:Izinto eziqashwe ngokucophelela zokuvikela inzwa nezinsiza zikagesi zihlinzeka ukumelana okuphezulu nokugqwala nokuguguleka, okuqinisekisa impilo ende yokusebenza ngisho nasezindaweni zokusebenza ezinzima.

4. Ubuchwepheshe Besiguquli Obuthuthukile:Ifakwe indlela entsha yokukhuthaza, isiguquli siqinisekisa ukusetshenziswa kwamandla aphansi, indawo yokuqala engaguquki, nokunemba okuphezulu kokukala nobubanzi obukhulu bokugeleza obufinyelela ku-150:1.

5. Izinketho Zokufakwa Eziguqukayo:Isiguquli singahlanganiswa nenzwa noma sifakwe ngokuhlukana, okuhlinzeka ngokuguquguquka okukhulu ezicelweni ezahlukene zezimboni.

6. Ukulawula Okuhlakaniphile Nokusebenza Okulula:Yakhiwe nge-microprocessor enokusebenza okuphezulu engu-16-bit kanye nesibonisi se-LCD esingu-2×16, izilungiselelo zepharamitha zilula, ukuhlela kunokwethenjelwa, futhi ukusebenza kulula kumsebenzisi.

7. Izinketho Eziphelele Zokulinganisa Nokukhipha:Uhlelo lokulinganisa olunezindlela ezimbili luhlanganisa amathothala amathathu (okuhamba phambili, okuhlehla, nokwahlukana). Lisekela okukhiphayo okuningi—ukugeleza kukagesi, i-pulse, ukuxhumana kwedijithali, ne-HART—okuhlangabezana nezidingo ezahlukene zezimboni.

8. Ukuzihlola Nokuxilonga Okunokwethenjelwa:Kusetshenziswa ubuchwepheshe obuthuthukisiwe be-Surface Mount Technology (SMT), isiguquli sihlanganise imisebenzi yokuzihlola nokuzixilonga ukuze kuqinisekiswe ukusebenza okunokwethenjelwa nokuzinzile.

9. Ukulinganisa Okunemba Okuphezulu:Isignali yamandla kagesi eyenziwayo ihlobene ngokuqondile nesilinganiso sokugeleza okumaphakathi, okuqinisekisa ukunemba okuphezulu kungakhathaliseki izinguquko zezici zoketshezi.

10. Impilo Ende Yokusebenza Ngaphandle Kwezingxenye Ezinyakazayo:Njengoba kungenazo izithiyo futhi kungenazo izingxenye ezinyakazayo epayipini lokulinganisa, inzwa ye-Lefoo inikeza ukulahleka komfutho okungaphezulu kweziro nokuqina okungavamile.

11. Isidingo Sepayipi Eliqondile Esifushane:Ngenxa yesignali yaso yomkhakha kazibuthe ogcwele indawo yonke, ubude bepayipi eliqondile obudingekayo buphindwe kahlanu kuphela kobubanzi bepayipi, okunciphisa ubunzima bokufaka.

12. Ukusebenza Kwesiguquli Sesizukulwane Elandelayo:Isebenza ngobuchwepheshe bakamuva be-MCU ne-SMT, isiguquli siqinisekisa ukusebenza okunokwethenjelwa, ukunemba okuphezulu, ukusetshenziswa kwamandla aphansi, nezilungiselelo ezilula kumsebenzisi, ngesibonisi se-LCD sedatha yokugeleza okuqoqiwe nokwamanje.

13. Uhlelo Oluzinzile Lokulinganisa Olunezindlela Ezimbili:Ama-electromagnetic flowmeter akwaLefoo asekela ukulinganisa kokugeleza okuphambili nokuhlehla. Ngobuchwepheshe obukhethekile bokukhiqiza nezinto ezisezingeni eliphezulu, ukusebenza komkhiqizo kuhlala kuzinzile isikhathi eside—okwenza uLefoo abe umenzi othembeleka wama-electromagnetic flowmeter emhlabeni jikelele.

Ukukhetha Kobungcweti Kwezinto Zokuvikela Zemitha Yokugeleza Kagesi kwaLefoo

Izakhiwo zokuvikela kufanele zikhethwe ngokuya ngamandla okugqwala, ukuguguleka, kanye nezinga lokushisa le-medium elinganiswayo:

Ukufakwa Kwe-Electromagnetic Flowmeter YakwaLefoo Kwenziwe Kwaba Lula Futhi Kusebenza

Ama-electromagnetic flowmeter asetshenziswa kabanzi emanzini angcolile, kumakhemikhali e-fluorine, emanzini okukhiqiza, embonini yamanzi ompompi, emithini, ensimbi nakwezinye izici eziningi. Ngenxa yomgomo, angakwazi ukukala uketshezi oluqhuba ugesi kuphela. Nakuba engcono kakhulu kunezinye izinhlobo zama-flowmeter mayelana nokwethembeka nokuzinza, amakhasimende azoqhubeka nokuhlangabezana nezinkinga ezithile ngesikhathi sokusebenza. Ake ngichaze kabanzi ukukhethwa nokufakwa kwama-electromagnetic flowmeter:

Okokuqala, njengamanye ama-flowmeter, nakuba i-electromagnetic flowmeter inesilinganiso sobubanzi bokukala esingu-30:1, esiphezulu kunesama-vortex flowmeter nama-differential pressure flowmeter, inemikhawulo futhi. Uma uyiqhathanisa nemitha yamanzi, kucatshangwa ukuthi ingakala izinga eliphansi kakhulu lokugeleza. Ngaphansi kwezimo ezijwayelekile, ingakala kuphela u-0.1m/s. Kunzima nge-electromagnetic flowmeter ukukala ngokunembile ngaphansi kwalesi silinganiso sokugeleza. Ngakho-ke, kuyadingeka ukucacisa isilinganiso sobubanzi bokugeleza ekuqaleni lapho ku-oda. Lapho ku-oda, akunakwenzeka uku-oda ngokobubanzi bepayipi bokuqala, kungcono ukunquma ububanzi bensimbi ngokuya ngokugeleza kwakho kwangempela.

Okwesibili, njengamanye ama-flowmeter, ama-electromagnetic flowmeter nawo anezidingo zamapayipi aqondile ngaphambi nangemuva kokufakwa, kodwa anezidingo eziphansi kunezinye izinhlobo zama-flowmeter, kodwa iphuzu elibaluleke kakhulu okufanele kuhlangatshezwe: okungukuthi, ipayipi kufanele ligcwele, bese kuthi-ke ipayipi kufanele ligcwele. Uma ipayipi lingagcwele, kulula ukubangela ukuthi i-flowmeter ixhumeke ngokungahleleki:

Okwesithathu, njengamanye ama-flowmeter, ama-electromagnetic flowmeter nawo anamazinga okuvikela. Ngokuvamile, izinga lokuvikela elihlanganisiwe ngu-IP65, kanti uhlobo oluhlukanisiwe lungu-IP68 (lwezinzwa). Uma ikhasimende linezidingo zendawo yokufaka yensimbi, indawo yokufaka ingaphansi komhlaba. Emithonjeni noma kwezinye izindawo ezimanzi, kunconywa ukuthi amakhasimende akhethe uhlobo oluhlukanisiwe. Ukuze kugwenywe ukulimala kwensimbi ngenxa yokukhetha okungalungile.

Okwesine, i-electromagnetic flowmeter ingakala uketshezi olugqwalayo, kodwa ekuqaleni kwe-oda, ikhasimende kufanele linikeze kahle ezinye izici ze-medium yokukala, ukuze kugwenywe amaphutha ekukhetheni i-electrode ngesikhathi sokukhetha, okungaholela ekutheni inzwa ilahlwe ngesikhathi sokusebenza kamuva, kube nokungalungi kumakhasimende nokulahlekelwa kwezomnotho.

Okwesihlanu, nakuba i-electromagnetic flowmeter inokwethembeka okuhle futhi ingeke yonakale ngaphansi kwezimo ezijwayelekile, ngenxa yomgomo wayo, ubuso be-electrode benzwa buhlala buthintana noketshezi. Ngemva kwesikhathi eside, ubuso be-electrode maningi amathuba okuba bungcoliswe. Ngakho-ke, ngokuvamile, lapho i-electromagnetic flowmeter ihlakazwa yikhasimende, kunconywa ukuthi i-electrode ihlakazwe futhi ihlanzwe kanye ngonyaka kuya eminyakeni eyodwa nengxenye ukuze kuqinisekiswe ukunemba kokulinganisa kwayo yonke i-flowmeter. Noma iyiphi insimba idinga "ukulungiswa", futhi ama-electromagnetic flowmeter awahlukile.

Okwesithupha, uma umugqa omkhulu ungowepayipi elimile, ngaphansi kwezimo ezijwayelekile, kudingeka ukuthi ukugeleza kwamanzi kube kusuka phansi kuya phezulu, futhi ungazami ukuthi kube phezulu kuya phansi. Lokhu kwakamuva kungabangela ukuguquguquka okukhulu kokugeleza. Ngaphandle kokufakwa kwamapayipi agcwele, lokhu nakho kubaluleke kakhulu, kulandelwa ibanga phakathi kwamapayipi aqondile angaphambili nangemuva.

Khetha indawo okulula ukuyilungisa futhi okulula ukuhamba kuyo. I-flowmeter kufanele ifakwe emaphethelweni angemuva epompiki, hhayi nhlobo ohlangothini lokumunca; ivelufu kufanele ifakwe ohlangothini oluya phansi kokugeleza.
