Ama-flowmeter e-electromagnetic, avame ukubizwa ngokuthi "ama-magmeter," ashintshe ukulinganiswa koketshezi kuzo zonke izimboni ngokusebenzisa uMthetho kaFaraday wokungeniswa kwe-electromagnetic ukuze anikeze idatha yokugeleza enembile, engaphazamisi. Ngokungafani nokuthembela kwawo kwendabuko kubuchwepheshe obuyinkimbinkimbi, lawa madivayisi anikeza izinzuzo ezihlukile ekuphatheni uketshezi oluyinselele—kusukela kumakhemikhali aqothulayo kuya kuma-slurry—okwenza abaluleke kakhulu emikhakheni efana nokwelashwa kwamanzi, ukucubungula amakhemikhali, kanye nokukhiqizwa kokudla.
Indlela Ama-flowmeter E-Electromagnetic Asebenza Ngayo
Enhliziyweni yazo, ama-magmeter asebenza ngesimiso sesayensi esilula: lapho uketshezi oluhambisayo lugeleza ensimini yamagnetic, lukhiqiza i-voltage encane kagesi ehambisana nejubane layo. I-meter inezingxenye ezine ezibalulekile:
- Ipayipi elingelona ele-magnetic elifakwe izinto zokuvikela ukushisa (ukuvimbela ukuphazamiseka kukagesi).
- Amakhoyili amabili kagesi adala insimu kazibuthe enqamula ipayipi.
- Ama-electrode afakwe ezinhlangothini eziphambene zepayipi ukuze kutholakale i-voltage ebangelwayo.
- I-transmitter eguqula le voltage ibe ukufundwa kwesilinganiso sokugeleza.
Njengoba i-voltage ilingana ngqo nejubane loketshezi, imitha ibala ivolumu yokugeleza ngokuphindaphinda ijubane ngendawo enqamula ipayipi. Okuphawulekayo ukuthi lo mklamo awunazo izingxenye ezihambayo, okususa izinkinga ezifana nokuvaleka noma ukuguguleka—izingibe ezivamile zama-flowmeter omshini.
Izinzuzo Eziyinhloko Zezicelo Zezimboni
Ama-flowmeter e-electromagnetic asebenza kahle kakhulu kunamadivayisi avamile ezindaweni eziningana ezibalulekile:
- Ukunemba Kuzo Zonke Izimo: Zigcina ukunemba (ngokuvamile okungu-±0.5% kokufundwa) kungakhathaliseki ukuthi uketshezi lungakanani, ukujiya, noma izinga lokushisa lini—okwenza zilungele uketshezi olufana nodaka, oluhlukahluka ngokuhambisana.
- Umklamo Ongaphazamisi: Njengoba kungekho zingxenye zangaphakathi eziphumayo ekugelezeni, ama-magmeter agwema ukwehla kwengcindezi, ukuvaleka, noma umonakalo ovela ezinhlayiyeni ezihuzukayo (isb., ezingcoleni zemayini). Lokhu kunciphisa ukugcinwa futhi kwandise impilo yenkonzo.
- Ukuguquguquka Ezinhlotsheni Zoketshezi: Ziphatha uketshezi oluhambisa umoya (kufaka phakathi amanzi, ama-asidi, namanzi angcolile) futhi zisebenza noketshezi oluhlanzekile ekukhiqizeni ukudla/iziphuzo, ngenxa yama-liners abushelelezi, okulula ukuwahlanza (isb., i-PTFE).
- Ukulinganisa Okuqondiswa Kabili: Ngokungafani namanye ama-flowmeter, ama-magmeter alinganisa ngokunembile ukugeleza kuzo zombili izinhlangothi—okubalulekile ezinhlelweni ezinokugeleza okuphambene, njengamanethiwekhi okusabalalisa amanzi.
Izinhlelo Zokusebenza Zangempela
Ukuguquguquka kwazo kwenza ama-flowmeter kagesi abe yinto ebalulekile ezimbonini ezahlukahlukene:
- Amanzi kanye namanzi angcolile: Asetshenziswa ukuqapha ukungenisa kwamanzi angavuthiwe, ukwelapha ukugeleza kokungcola, kanye nokuthola ukuvuza ezimisweni zokusabalalisa.
- Ukucubungula Amakhemikhali: Kala uketshezi olubolayo noma olunobuthi (isb., ama-asidi, ama-alkali) ngaphandle kwengozi yokungcola noma umonakalo wemitha.
- Ukudla Neziphuzo: Amamodeli okuhlanzeka anezimbobo ezivunyiwe yi-FDA alandelela ukugeleza kokukhiqizwa kobisi, ujusi, noma ubhiya, okuqinisekisa ukuhlanzeka nokuhambisana nomthetho.
- Ukumba: Ukugeleza kodaka oluphethe izinto eziqinile (isb. izinhlayiya zensimbi), lapho amamitha omshini angaguga khona ngokushesha.
Izinto Okumelwe Zicatshangelwe Ekusetshenzisweni
Nakuba zisebenza kahle kakhulu, ama-magmeter anemikhawulo okufanele ayiqaphele:
- Zidinga ukuthi uketshezi lukwazi ukudlulisa ugesi (≥5 ¥S/cm2), okuvimbela ukusetshenziswa namafutha noma amagesi.
- Ukufakwa okufanele (isib., ukuqinisekisa ukugeleza kwamapayipi okugcwele, ukugwema izakhiwo zensimbi eziseduze) kubalulekile ukugwema ukuphazamiseka kukazibuthe.
- Izindleko zokuqala ziphakeme kunezimitha zomshini, yize izidingo zokulungisa eziphansi zivame ukuqeda lokhu ngokuhamba kwesikhathi.
Isiphetho
Ama-flowmeter e-electromagnetic ahlanganisa ukusungula izinto ezintsha kwesayensi nomklamo osebenzayo, anikeza ukulinganisa ukugeleza okuthembekile, okungadingi ukunakekelwa okuningi ezindaweni zezimboni eziyinselele. Ngokususa izingxenye ezihambayo nokuzivumelanisa noketshezi oluhlukahlukene, axazulula izinkinga ezinde ngokunemba nokuqina. Njengoba izimboni ziqhubeka zifuna ukulawulwa kwenqubo okunembile nokuphumelelayo, ama-magmeter azohlala eyitshe lesisekelo lobuchwepheshe besimanje bokulinganisa ukugeleza.
