Yiziphi izici zokusebenza zemitha yokugeleza kwe-electromagnetic ekwazi ukumelana ne-asidi?

I-acid-resident ehlakaniphilei-electromagnetic flow meterinezici zokunemba okuphezulu, ukwethembeka okuphezulu kanye nempilo ende yenkonzo. Ukuze kuqinisekiswe ikhwalithi yomkhiqizo, ucwaningo lwesayensi oluningiliziwe kanye nokukhohlisa esigabeni ngasinye, ukusekela izikhungo ezinemininingwane yesistimu yokuqapha ukulinganisa ukugeleza okuphelele. Ukuze kuhlangatshezwane nezidingo zesilinganiso ngaso leso sikhathi, sakha futhi saklama isofthiwe yesistimu yemitha yokugeleza kwe-acid enengcindezi ephezulu, isofthiwe yesistimu yemitha yokugeleza kagesi ekwazi ukumelana ne-acid, ikakhulukazi i-plug-in-resistant. imitha yokugeleza kuka-electromagnetic ehlakaniphile kusofthiwe yohlelo lwamapayipi omthamo omkhulu Uhlelo lokusebenza oluphakathi lunomnotho omuhle kakhulu, ukusebenziseka, ukuhambisana nesikhathi nokwethembeka. Uhlobo lokufakwa ku-inthanethi lungafakwa futhi lugcinwe ngaphandle kokumisa umsebenzi, futhi isicelo silula. Thuthukisa isofthiwe yesistimu yemitha yokugeleza kagesi ekwazi ukumelana ne-asidi efanele izimboni ezihlukahlukene ezifana nowoyela ongahluziwe, izitshalo zamakhemikhali, amandla kagesi, imboni yensimbi, ukudla, ukuvikelwa kwemvelo, nobunjiniyela bokonga amanzi.

Isimiso semitha yokugeleza kwe-electromagnetic eqinile engamelana ne-asidi:
Umgomo wemitha yokugeleza ehlakaniphile engamelana ne-asidi usekelwe emthethweni oyisisekelo womphumela kazibuthe we-Faraday current. Kumitha yokugeleza kwe-electromagnetic ukumelana ne-asidi, i-conductive medium kushubhu yokulinganisa ilingana ne-conductive iron rod ocwaningweni lwe-Faraday, futhi amakhoyili kazibuthe amabili ohlangothini lwesobunxele nakwesokudla adala inkambu ye-electromagnetic ezinzile. Lapho i-conductive medium idlula, izodala i-voltage engenisiwe. I-voltage ebangelwe ukulinganiswa kwama-electrode amabili ngaphakathi kwepayipi. Ipayipi lokulinganisa liqedela ukuvikelwa kokungeniswa kuka-electromagnetic ngoketshezi kanye ne-electrode yokulinganisa ngokuya kolwelwesi olungaqhubeki (irabha evuvukele, iTeflon, njll.).
Izici eziyinhloko zobuhlakani obumelana ne-asidiimitha yokugeleza kagesi:
♦Imitha yokugeleza kwe-electromagnetic ekwazi ukumelana ne-asidi ivuliwe futhi ayinazo izithiyo ngaphakathi, ngaphandle kokulimala kwengcindezi nokuvinjwa koketshezi.
♦Awekho amandla emishini esetshenziswayo, ukusabela okusheshayo, ububanzi bokulinganisa uketshezi olubanzi (izinga lokugeleza kwamanzi 0.3-12m/s), ukwethembeka okuhle, futhi ingasetshenziselwa ukuhlonza okuzenzakalelayo, ukulungisa kanye nesofthiwe yokulawula uhlelo.
♦Linganisa uketshezi nge-conductivity edlula i-5u S/cm, ukulinganisa ngeke kulinyazwe ukuguqulwa kwe-fluid density, viscosity, izinga lokushisa, ingcindezi yokusebenza kanye ne-conductivity. Isignali yedatha yedatha yenzwa yenzwa ihlobene ngokuhambisana nokugeleza kwamanzi okumaphakathi, futhi ukulinganisa kunembe kakhulu.
♦Amazinga okunemba: 0.2, 0.5, 1.0, 1.5. Ingacabangela izidingo zamakhasimende ahlukene.
♦Ingxenye yenzwa inomugqa kuphela kanye ne-electrode exhumene noketshezi okumele lukalwe. Uma ukhetha izinto ezifanele ze-electrode ne-lining, ingamelana nokugqwala nokuguga.
♦Imitha yokugeleza kwe-electromagnetic ekwazi ukumelana ne-asidi ihlukaniswe yaba uhlobo oluyisisekelo (ingcindezi yokusebenza ≤4.0MPa) kanye nohlobo lwengcindezi ephezulu (ingcindezi yokusebenza ≥4.0MPa).
♦Isofthiwe yesistimu ye-electromagnetic flowmeter ehlakaniphile engangeni kwi-acid ihlukaniswe yaba uhlobo lokufaka olulula nohlobo lokufakwa ku-inthanethi.
♦Inkumbulo ye-EEPROM ikhethiwe, futhi ukugcinwa kolwazi lwedatha yesilinganiso nokubala kanye nokugcinwa kungathenjwa.
♦Khetha umklamo omuhle kakhulu wamazwe omhlaba we-single-chip microcomputer (MCU) kanye nobuchwepheshe bokufaka i-surface mount (SMT), izici ezinokwethenjelwa, ukunemba okuphezulu, ukulahleka kokusebenza okuphansi, iphoyinti eliziro elizinzile, izinhlu zokuphindaphinda zesiShayina, nokusetha okulula kwamapharamitha ayinhloko.
