I-Coriolis Mass Flow Measurement
I-Coriolis mass flow metresthatha isiqongo sobuchwepheshe esilinganisweni soketshezi lwezimboni. Izimboni eziningi ezifana nowoyela negesi, ukukhiqizwa kokudla kanye nemithi zinamathisela ukubaluleka ekusebenzeni kahle, ukuphepha, ukunemba nokulawulwa kwezindleko. Ukuqonda okungenakuqhathaniswa kokuguquguquka kokugeleza nakho kuyisizathu sokuduma kwawo, ukulinganisa ukugeleza kwenqwaba ngokuqondile kunezibalo ezingaqondile ezisekelwe kungcindezi nezinga lokushisa. Idivayisi eletha ukufundwa okunembayo ngesikhathi sangempela esimweni sezulu esiyinselele noma izimo zokucubungula ayishodi ngoshintsho lwegeyimu, ikakhulukazi ezimbonini ezidonsa kanzima ezintweni eziguquguqukayo eziyinkimbinkimbi.
Iyini I-Mass Flow Meter?
I-mass flow meter isetshenziselwa ukukala izinga lokugeleza koketshezi oludlula epayipini ngaphandle kokuphazamisa yonke inqubo yokukhiqiza. Ikala ukuthunyelwa kwenqwaba ngepayipi ngesikhathi seyunithi. Ukukalwa kokugeleza okukhulu kuthathwa njengesisekelo esibalulekile sokwenziwa kweresiphi eminingi, ukunqunywa kwebhalansi yezinto ezibonakalayo, inkokhiso kanye nokudluliselwa kwesitokisi ezimbonini ezihlobene. Ukuthembeka nokunemba kubaluleke kakhulu ezinhlelweni ezinjalo.
Isebenza Kanjani I-Mass Flow Meter?
Ubuchwepheshe obubili obuhlukene obusetshenziswa ekulinganisweni kwesisindo yi-inertial ne-thermal. Imitha ye-inertia yangaphambili yaziwa ngokuthi yi-Coriolis flow metres encike kumphumela we-Coriolis. Uketshezi oludlula epayipini lubhekana nokusheshisa kwe-Coriolis ngokwethulwa ngomshini kokujikeleza okubonakalayo epayipini. Amandla achezukayo akhiqizwa ohlelweni lokugeleza kwamanzi azoba umsebenzi wezinga lokugeleza kwesisindo esilinganisiwe.
Kamuvaimitha ye-thermal mass flowkala izinga lokugeleza kwamagesi noketshezi ngokuqondile. Ukuthi yethula amanani athile okushisa emfudlaneni ogelezayo noma igcina i-probe ezingeni lokushisa elingashintshi, imitha yokugeleza kwe-thermal mass isebenza nezinzwa ezimbili zamazinga okushisa kanye ne-heater kagesi. Isigaba esingenhla siyachazaukuthi i-thermal mass flow meter isebenza kanjani.
Uyini umgomo we-Mass Flow Meter?
I-mass flow meters ihlose ukulinganisa isisindo sento egeleza endaweni ethile ngesikhathi seyunithi ngayinye. Kepha ziyahlukahluka kubuchwepheshe bokulinganisa okuqondile okuqondisiwe njenge-thermal, i-Coriolis, i-ultrasonic noma i-vortex. II-Coriolis mass flow meteringenye yemitha yokugeleza ethandwa kakhulu ngokunemba nokuthembeka kwayo.
Ukunemba Nokwehlukahlukana Kwamamitha Okugeleza Okukhulu
Ngenxa yokunemba okuvelele nokuphindaphinda, amamitha okugeleza kwenqwaba athandwa ezimbonini ezinamathisela ukubaluleka kokunemba. Ukuhlukahluka kwamamitha okugeleza okukhulu kubhekisela ebangeni eliphezulu abangalilinganisa. Ibanga lemitha lokugeleza kwesisindo lilingana ngokuphambene nokungalungi kwalo ngokujwayelekile. Izizathu zobudlelwano obunjalo zilele kuzinzwa zokuzwela okuthulisa ezifakwe kumamitha okugeleza obubanzi obubanzi, angazweli njengalawo mamitha okugeleza obubanzi obuncane anokuzwela okukhulu.
Ungakukhetha Kanjani Ukuhlukahluka Okufanelekile Kwamamitha Okugeleza?
Izinto ezifana nohlobo lwe-fluid, ububanzi bokugeleza, ukunemba, izinga lokushisa nokucindezela kufanele kucatshangelwe lapho kukhethwa imitha yokugeleza efanelekile ngokusekelwe ekusebenziseni okungokoqobo. Ububanzi bokugeleza yinto yokuqala okufanele inqunywe ngaphambi kokukhetha ububanzi obufanele besikali esigcwele. Amamitha okugeleza kwesisindo sobubanzi obuncane akhethwa ukuze kube nokunemba okuphezulu uma ububanzi bokugeleza buncane. Ngaphandle kwalokho, izinga lokushisa le-ambient nokucindezela kuyizici ezengeziwe ezithonya ukunemba kokugcina. Imitha yokugeleza kwenqwaba ekwazi ukumelana nezinga lokushisa eliphezulu kanye nokucindezela kuthatha kuqala ekukhetheni uma izinga lokushisa nokucindezela kuphezulu.
Amamitha okugeleza kwesisindo se-Coriolis esuka e-Lonnmeter anikeza u-0.1% - 0.05% wokunganembi kwesilinganiso kububanzi bokugeleza obufika ku-100:1. Ukuhlukahluka kwamashubhu ejika kubanzi kunalokho kwamamitha eshubhu eliqondile. Iphutha eliphelele lemitha liqukethe kokubili ukunganembi kwesisekelo kanye nephutha lika-zero-shift, okuwumphumela wokuphuma kwesignali okungavamile kusimo sokugeleza kweziro. Iphutha lika-zero-shift liyisizathu esiyinhloko sephutha, libalelwa ku-1% -2% wesilinganiso esilinganisiwe esijwayelekile.
Abanye abakhiqizi bakhombisa ukunemba kukonke ngendlela yephesenti lokugeleza kokugeleza okuphezulu kanye nephesenti lokugeleza kanye nephutha le-zero-shift. Kubalulekile ukuthi ubuyekeze imininingwane lapho wenza isiqhathaniso ngenxa yobuqili obuhilelekile.
Izicelo Nemikhawulo Yamamitha Okugeleza Okukhulu
Amamitha okugeleza okukhulu athambekele ekuthonyweni ukuguquguquka kwemvelo, ukufundwa, ukubala; ukulungiswa kwephutha kungase kubangele umonakalo ongaba khona kumishini, ukwehla kokusebenza kahle kanye nokunciphisa ukunemba. Bheka izinkinga ezilandelayo zingase zenzeke kumamitha agelezayo:
Cha.1 Ingcindezi ingase yehle uma isivinini sokugeleza sikhuphuka ukuze sibonwe;
No.2 Coriolis metres ayabiza kunamanye ama-flow metres. Futhi awakwazanga ukusetshenziswa emapayipini amakhulu.
No.3 Ukujiya komswakama kumagesi agcwele kungase kubangele ukufundwa okuphansi kanye nokugqwala okuhambisanayo.
No. 4 Ukwemboza noma ukwakheka kwempahla kwinzwa kuzothonya ukusebenza kahle kokudlulisa ukushisa.
Naphezu kwezindleko zokuqala eziphakeme, izinzuzo zesikhathi eside zokunemba, ukugcinwa okuphansi nokuqina zishiya amamitha okugeleza kwe-Coriolis abe yisixazululo esifanelekile ezimbonini eziningi. Izilinganiso eziqondile nezithembekile zesisindo, ukuminyana nezinga lokushisa ziwashiya eguquguqukayo ukusuka kuwoyela, igesi kuya ekudleni nesiphuzo.
Sicela uzizwe ukhululekile ukusithinta futhi uthintane nochwepheshe ukuze ukhethe amamitha okugeleza kwesisindo alungile uma uthola umkhiqizi onokwethenjelwa we-Coriolis mass flow meters. Noma vele ucele ikhotheshini yamahhala enezidingo ezithile.
