Kulawulo lweenkqubo zoshishino, uphando lwesayensi, kunye norhwebo, ukulinganisa ngokuchanekileyo ukuhamba kolwelo kubalulekile. Ngokungafaniyo neemitha zokuhamba komthamo—ezinokufundwa kwazo okujijeka lula kutshintsho lobushushu kunye noxinzelelo—iimitha zokuhamba kobunzima (ii-MFM) zilinganisa ngokuthe ngqo okanye ngokungathanga ngqo ubunzima bolwelo oludlula kumbhobho, ukuqinisekisa ukuchaneka okuhlala kusenzeka nokuba imeko yokusingqongileyo injani na. Oku kuzenza zibe yimfuneko kumacandelo aqala ekucoceni ioyile ukuya ekuvelisweni kwee-semiconductor.
Imigaqo Engundoqo: Kutheni Iimitha Zokuhamba Kobunzima Zibalulekile
Umthamo wolwelo luyinto eguquguqukayo exhomekeke kubushushu kunye noxinzelelo; umzekelo, igesi iyakhula phantsi kobushushu obuphezulu, nto leyo ekhokelela ekulinganisweni okungachanekanga okusekwe kumthamo. Ngokwahlukileyo koko, ubunzima bolwelo buhlala buhleli, nto leyo eyenza ukuba lube yiparameter efanelekileyo yokujonga ukuhamba ngokuchanekileyo. Iimitha zokuhamba komthamo zemveli zifuna ukulungiswa okongeziweyo koxinano, ubushushu, kunye noxinzelelo, nto leyo engenisa amanqaku amaninzi empazamo. Iimitha zokuhamba kobuninzi zisusa obu bunzima ngokujolisa ubunzima ngokuthe ngqo, nokuba ngeziphumo zomzimba (umz., amandla eCoriolis) okanye izibalo ezifunyenweyo (ukudibanisa idatha yokuhamba komthamo kunye noxinano).
Iintlobo eziphambili zeeMeter zokuhamba kobunzima
Iimitha zokuhamba kobunzima zahlulwe ngokubanzi zibe ziintlobo ezithe ngqo (ukulinganisa ukuhamba kobunzima ngokuthe ngqo) kunye nohlobo olungathanga ngqo (ukubala ukuhamba kobunzima kwezinye iiparameter), nganye inamandla awodwa kwizicelo ezithile.
1. Iimitha zoMsinga woBunzima zohlobo oluthe ngqo
- Iimitha zokuHamba koMbane zeCoriolis (iiCMFM): Umgangatho ogqwesileyo wokuchaneka okuphezulu, iiCMFM zisebenzisa isiphumo seCoriolis—esaqala ukubonwa ngo-1832—ukulinganisa ukuhamba kobunzima. I-CMFM eqhelekileyo ineetyhubhu ezimbini ezingcangcazelayo ezihambelanayo (ezihlala zimile okwe-U okanye ezithe tye) eziqhutywa yi-electromagnetic coil. Njengoko ulwelo luhamba kwiityhubhu, luvelisa amandla okujika ahambelana nokuhamba kobunzima balo, nto leyo edala umahluko wesigaba phakathi kweenzwa ezisekupheleni kwetyhubhu. Lo mahluko wesigaba uguqulela ngokuthe ngqo ukuhamba kobunzima. IiCMFM zikwalinganisa uxinano lolwelo (ngokusebenzisa i-tube vibration frequency) kunye nobushushu (ngokusebenzisa iinzwa ezakhelwe ngaphakathi), nto leyo ezenza zibe nokuguquguquka kwizinto ezimanzi, iigesi, kunye ne-slurry. Ukuchaneka kwazo (±0.1% ukuya ku-±0.5%) kunye neemfuno ezincinci zepayipi ethe tye zihambelana neemeko ezibalulekileyo ezifana norhwebo lweoyile kunye nokulinganisa amayeza.
- IiMetha zoMsinga woBunzima boBushushu (iiTMFM): Zilungele ukulinganisa igesi, iiTMFM zisebenzisa imigaqo yokudlulisa ubushushu. Isensa eshushu kunye nesensa yokubhekisa ijonga umahluko wobushushu: njengoko ulwelo luhamba, luyapholisa isensa eshushu, kwaye amandla afunekayo ukugcina ubushushu obungaguqukiyo (okanye ukuhla kobushushu ngokwako) ahambelana nokuhamba kobunzima. Zigqwesile kumazinga aphantsi okuhamba (umz., iigesi zenkqubo ye-semiconductor) kwaye zibonelela ngomlinganiselo obanzi wokujika (ukuya kuthi ga kwi-100:1). Nangona kunjalo, azifanelekanga kangako kwiilwelo ezinoburhabaxa obuphezulu okanye iigesi ezinee-compositions eziguquguqukayo, njengoko ukudluliselwa kobushushu kuxhomekeke kumthamo othile wobushushu.
2. Iimitha zoMsinga woBunzima obungathanga ngqo
Ezi zikwabizwa ngokuba zii-“derived” MFMs, ezi zidibanisa iimitha zokuhamba komthamo kunye neesensa ezincedisayo ukubala ukuhamba kobunzima. Uqwalaselo oluqhelekileyo luquka:
- Imitha Yokuhamba Komthamo + Imitha Yoxinano: I-turbine okanye imitha yobungakanani be-ultrasonic ilinganisa izinga lokuhamba, ngelixa imitha yoxinano (umz., ifolokhwe engcangcazelayo) inika idatha yoxinano ngexesha langempela. Ukuhamba kobuninzi kubalwa njengemveliso yokuhamba komthamo kunye noxinano.
- Iimitha eziHlanganisiweyo zoXinzelelo loBushushu: Kwiinzingo ezinolwazi oluqhelekileyo malunga noxinano lobushushu noxinzelelo (umz., igesi yendalo), imitha yomthamo edibene neenzwa zobushushu/uxinzelelo ilungisa ukufundwa kwezixhobo ngokweemeko eziqhelekileyo, nto leyo efumana ukuhamba kobunzima ngokungathanga ngqo. Ezi azibizi kakhulu kodwa azichanekanga kangako kunee-MFM zohlobo oluthe ngqo, ezifanelekileyo ukujonga izinto zoshishino ezingabalulekanga.
Izicelo zeShishini kunye neMigqaliselo yoKhetho
Iimitha zokuhamba kobunzima zisebenzela amacandelo ahlukeneyo:
- Ioyile neGesi: IiCMFM ziqinisekisa umlinganiselo ochanekileyo wamafutha kwiindawo zokucocisa kunye norhwebo oluchanekileyo lweoyile ekrwada.
- Iikhemikhali: IiTMFM zijonga ukuhamba kwegesi enobuthi okanye erhabaxa, ngelixa iiCMFM zijonga ulwelo oluqinileyo olufana neepolymers.
- Ukutya Neziselo: IiCMFM zococeko (ezineetyhubhu zentsimbi engagqwali ezingama-316L) zilinganisa iioyile ezityiwayo okanye iimveliso zobisi ngaphandle kwemingcipheko yongcoliseko.
- Ii-semiconductors: Ii-TMFM zilawula ukuhamba kwegesi okumsulwa kakhulu (umz., i-nitrogen, i-argon) ekwenzeni iitships.
Xa ukhetha i-MFM, izinto ezibalulekileyo ziquka:
- Iimpawu zolwelo: Ukubola, ukuxinana, kunye nesigaba (ulwelo/igesi/ukutyibilika) zilawula ukuhambelana kwezinto (umz., iHastelloy yee-asidi).
- Iimfuno zokuChaneka: ii-CMFM zemisebenzi ebalulekileyo yorhwebo xa kuthelekiswa nee-MFM ezingathanga ngqo ezingabizi kakhulu zokubeka esweni ngokubanzi.
- Imiqobo Yokufakelwa: IiTMFM zifuna indawo encinci, ngelixa iiCMFM zinyamezela imibhobho ethe tye elinganiselweyo.
Ukuqukumbela, iimitha zokuhamba kobunzima ziye zaguqula umlinganiselo wokuhamba ngokubeka phambili ukuchaneka nokuthembeka. Ukusuka kwiimitha zeCoriolis ezichanekileyo kakhulu ukuya kuyilo lobushushu olungabizi kakhulu, ukuguquguquka kwazo kuqinisekisa ukuba ziyahlangabezana neemfuno zeenkqubo zanamhlanje zoshishino, ziqhuba ukusebenza kakuhle kunye nomgangatho kwiikhonkco zobonelelo zehlabathi.
