Ekulawuleni izinqubo zezimboni, ocwaningweni lwesayensi, kanye nokuhweba ngezohwebo, ukulinganisa okunembile kokugeleza koketshezi kubalulekile. Ngokungafani namamitha okugeleza komthamo—okufundwa kwawo kuphambuka kalula ngenxa yokushintsha kwezinga lokushisa kanye nokucindezela—amamitha okugeleza kobuningi (ama-MFM) alinganisa ngokuqondile noma ngokungaqondile isisindo soketshezi oludlula epayipini, ukuqinisekisa ukunemba okuqhubekayo kungakhathaliseki izimo zemvelo. Lokhu kuwenza abaluleke kakhulu emikhakheni esukela ekuhlanzeni uwoyela kuya ekukhiqizweni kwe-semiconductor.
Izimiso Eziyinhloko: Kungani Amamitha Okugeleza Kwesisindo Ebalulekile
Umthamo woketshezi uyinto eguquguqukayo encike ekushiseni nasekucindezelweni; isibonelo, igesi iyakhula ngaphansi kwamazinga okushisa aphezulu, okuholela ekulinganisweni okungalungile okusekelwe kumthamo. Ngokuphambene nalokho, isisindo soketshezi sihlala singaguquguquki, okwenza kube yipharamitha efanelekile yokuqapha ukugeleza okunembile. Amamitha okugeleza komthamo wendabuko adinga ukulungiswa okwengeziwe kobuningi, izinga lokushisa, kanye nokucindezela, okuletha amaphuzu amaningi amaphutha. Amamitha okugeleza komthamo aqeda lobu bunzima ngokubhekisa ngqo kumthamo, kungaba ngemiphumela ebonakalayo (isb., amandla eCoriolis) noma izibalo ezithathwe (ukuhlanganisa idatha yokugeleza komthamo kanye nobuningi).
Izinhlobo Eziyinhloko Zamamitha Okugeleza Kwesisindo
Amamitha okugeleza kwesisindo ahlukaniswe kabanzi ngohlobo oluqondile (ukulinganisa ukugeleza kwesisindo ngqo) kanye nohlobo olungaqondile (ukubala ukugeleza kwesisindo kusuka kwamanye amapharamitha), ngalinye linamandla ahlukile ezinhlelo zokusebenza ezithile.
1. Amamitha Okugeleza Kwesisindo Sohlobo Oluqondile
- Ama-Coriolis Mass Flow Meters (ama-CMFM): Izinga eliyigolide lokunemba okuphezulu, ama-CMFM asebenzisa umphumela we-Coriolis—owatholakala okokuqala ngo-1832—ukukala ukugeleza kobuningi. I-CMFM ejwayelekile inamapayipi amabili adlidlizayo ahambisanayo (ngokuvamile anomumo we-U noma aqondile) aqhutshwa yi-electromagnetic coil. Njengoba uketshezi lugeleza ngamapayipi, lukhiqiza amandla okujika alingana nokugeleza kwalo kobuningi, okudala umehluko wesigaba phakathi kwezinzwa emaphethelweni epayipi. Lo mehluko wesigaba uhumusha ngokuqondile ukugeleza kobuningi. Ama-CMFM aphinde alinganise ubuningi boketshezi (ngokusebenzisa imvamisa yokudlidliza kwepayipi) kanye nokushisa (ngama-sensor akhelwe ngaphakathi), okwenza abe nezimo ezihlukahlukene zoketshezi, amagesi, kanye ne-slurry. Ukunemba kwawo (±0.1% kuya ku-±0.5%) kanye nezidingo ezincane zamapayipi aqondile kuhambisana nezimo ezibalulekile njengokuhweba ngamafutha kanye nokulinganisa imithi.
- Ama-Thermal Mass Flow Meters (TMFMs): Afanelekela ukulinganisa igesi, ama-TMFM asebenzisa izimiso zokudlulisa ukushisa. Inzwa efudumele kanye nenzwa yokubhekisela iqapha umehluko wokushisa: njengoba ukugeleza koketshezi, kuyapholisa inzwa efudumele, futhi amandla adingekayo ukugcina izinga lokushisa elihlala likhona (noma ukwehla kokushisa ngokwako) kuhlobene nokugeleza kobuningi. Ahamba phambili ngamanani aphansi okugeleza (isb., amagesi enqubo ye-semiconductor) futhi anikeza isilinganiso esibanzi sokujika (kufika ku-100:1). Kodwa-ke, awafaneleki kangako uketshezi olunamandla noma amagesi anezinhlanganisela eziguquguqukayo, njengoba ukudluliselwa kokushisa kuncike kumthamo othile wokushisa.
2. Amamitha Okugeleza Kwesisindo Ohlobo Olungaqondile
Futhi okubizwa ngokuthi ama-MFM “atholakalayo”, lawa ahlanganisa amamitha okugeleza kwevolumu nezinzwa ezisizayo ukuze kubalwe ukugeleza kwesisindo. Ukulungiswa okuvamile kufaka phakathi:
- Imitha Yokugeleza Kwevolumu + Imitha Yobuningi: I-turbine noma imitha yobuningi be-ultrasonic ilinganisa izinga lokugeleza, kuyilapho imitha yobuningi (isb., ifoloko elidlidlizayo) inikeza idatha yobuningi besikhathi sangempela. Ukugeleza kwesisindo kubalwa njengomkhiqizo wokugeleza kwevolumu kanye nobuningi.
- Amamitha Akhokhelwa Ukucindezela Kokushisa: Kumanzi anobudlelwano obaziwayo bokuqina nokushisa nokucindezela (isb. igesi yemvelo), imitha yomthamo ehlanganiswe nezinzwa zokushisa/ukucindezela ilungisa ukufundwa kwezimo ezijwayelekile, ithole ukugeleza kobuningi ngokungaqondile. Lawa angabizi kakhulu kodwa awanembile kangako kune-MFM yohlobo oluqondile, afanelekela ukuqapha izimboni okungabalulekile.
Izicelo Zezimboni kanye Nezindlela Zokukhetha
Amamitha okugeleza kwesisindo asebenzela imikhakha eyahlukahlukene:
- Uwoyela negesi: Ama-CMFM aqinisekisa ukulinganisa okunembile kukaphethiloli ezindaweni zokuhluza kanye nokuhweba okunembile kwamafutha angahluziwe.
- Amakhemikhali: Ama-TMFM aqapha ukugeleza kwegesi enobuthi noma egqwalisayo, kuyilapho ama-CMFM ephatha uketshezi oluqinile njengama-polymer.
- Ukudla Neziphuzo: Ama-CMFM ahlanzekile (anezimbobo zensimbi engagqwali ezingama-316L) alinganisa amafutha adliwayo noma imikhiqizo yobisi ngaphandle kwezingozi zokungcola.
- Ama-semiconductor: Ama-TMFM alawula ukugeleza kwegesi okumsulwa kakhulu (isb., i-nitrogen, i-argon) ekwakhiweni kwama-chip.
Uma ukhetha i-MFM, izici ezibalulekile zifaka:
- Izakhiwo Zoketshezi: Ukugqwala, i-viscosity, kanye nesigaba (uketshezi/igesi/i-slurry) kulawula ukuhambisana kwezinto (isb., i-Hastelloy yama-asidi).
- Izidingo Zokunemba: Ama-CMFM emisebenzi ebalulekile kwezohwebo uma kuqhathaniswa nama-MFM angaqondile angabizi okuqapha okuvamile.
- Izithiyo Zokufaka: Ama-TMFM adinga isikhala esincane, kuyilapho ama-CMFM ebekezelela ipayipi eliqondile elilinganiselwe.
Ekuphetheni, amamitha okugeleza ngobuningi ashintshe indlela okukalwa ngayo ukugeleza ngokubeka phambili ukunemba nokuthembeka. Kusukela kumamitha e-Coriolis anembile kakhulu kuya emiklamo yokushisa engabizi kakhulu, ukuguquguquka kwawo kuqinisekisa ukuthi ayahlangabezana nezidingo zezinqubo zezimboni zanamuhla, okuqhuba ukusebenza kahle kanye nekhwalithi emigqeni yokuphakelwa komhlaba wonke.
