Ukulinganiswa Kokugeleza Kwesisindo Se-Coriolis
Amamitha okugeleza kobuningi beCoriolisIthatha indawo evelele yobuchwepheshe ekulinganisweni koketshezi lwezimboni. Izimboni eziningi ezifana nowoyela negesi, ukukhiqizwa kokudla kanye nemithi zibeka ukubaluleka ekusebenzeni kahle, ukuphepha, ukunemba kanye nokulawula izindleko. Ukuqonda okungafani nokuguquguquka kokugeleza nakho kuyisizathu sokuthandwa kwazo, kulinganisa ukugeleza kobuningi ngqo kunokubala okungaqondile okusekelwe ekucindezelweni kanye nokushisa. Idivayisi enikeza ukufundwa okunembile ngesikhathi sangempela esimweni sezulu esinzima noma izimo zokucubungula ayiyona into edlula ukushintsha umdlalo, ikakhulukazi ezimbonini ezibhekene nezimo eziyinkimbinkimbi.
Iyini i-Mass Flow Meter?
Imitha yokugeleza kwesisindo isetshenziselwa ukukala izinga lokugeleza koketshezi oludlula epayipini ngaphandle kokuphazamisa yonke inqubo yokukhiqiza. Ikala ukuthunyelwa kwesisindo ngepayipi ngesikhathi seyunithi ngayinye. Ukulinganiswa kokugeleza kwesisindo kubhekwa njengesisekelo esibalulekile sezindlela zokupheka eziningi, ukunqunywa kwebhalansi yezinto ezibonakalayo, ukukhokhisa kanye nokudluliselwa kokugcinwa kwezimpahla ezimbonini ezihlobene. Ukuthembeka nokunemba kubaluleke kakhulu kulezi zinhlelo zokusebenza.
Isebenza Kanjani Imitha Yokugeleza Kwesisindo?
Ubuchwepheshe obubili obuhlukene obusetshenziswa ekulinganisweni kwesisindo yi-inertial kanye ne-thermal. I-inertia meter yangaphambili yaziwa ngokuthi i-Coriolis flow meter encike kumphumela we-Coriolis. Amanzi adlula epayipini afakwa ekusheshisweni kwe-Coriolis ngokufakwa komshini kokujikeleza okubonakalayo epayipini. Amandla okuphambuka akhiqizwa enkambisweni yokugeleza koketshezi azoba umsebenzi wesilinganiso sokugeleza kwesisindo esilinganisiwe.
Kamuvaimitha yokugeleza kwesisindo sokushisalinganisa izinga lokugeleza kwamagesi noketshezi ngqo. Kungakhathaliseki ukuthi kungeniswa amazinga athile okushisa emfudlaneni ogelezayo noma kugcinwa i-probe ekushiseni okungaguquki, imitha yokugeleza kwesisindo sokushisa isebenza ngezinzwa ezimbili zokushisa kanye ne-heater kagesi. Isigaba esingenhla siyachaza.indlela imitha yokugeleza kwesisindo sokushisa esebenza ngayo.
Iyini isimiso se-Mass Flow Meter?
Amamitha okugeleza kwesisindo ahlose ukukala isisindo sento egeleza endaweni ethile ngesikhathi seyunithi ngayinye. Kodwa ayahlukahluka ngobuchwepheshe bokulinganisa okuqondile okuqondiswe njengokushisa, i-Coriolis, i-ultrasonic noma i-vortex.Imitha yokugeleza kwesisindo seCoriolisingenye yezindlela zokulinganisa ukugeleza ezithandwa kakhulu ngenxa yokunemba kwayo nokuthembeka kwayo.
Ukunemba Nokuguquguquka Kwamamitha Okugeleza Okukhulu
Ngenxa yokunemba okuvelele kanye nokuphindaphindeka, amamitha okugeleza kobuningi ayathandwa ezimbonini ezifaka ukubaluleka kokunemba. Ububanzi bamamitha okugeleza kobuningi bubhekisela ebangeni eliphezulu abangalilinganisa. Ububanzi bemitha yokugeleza kobuningi buhambisana ngokuphambene nokungalungi kwayo ngokujwayelekile. Izizathu zobudlelwano obunjalo zisezinzwa zokuzwela kokuthula ezifakwe kumamitha okugeleza obubanzi, ezingazweli njengalawo mamitha okugeleza obubanzi obuncane ane-hypersensitivity.
Ungayikhetha Kanjani I-Rangeability Efanele Yama-Flow Meters?
Izinto ezifana nohlobo loketshezi, ububanzi bokugeleza, ukunemba, izinga lokushisa kanye nengcindezi kufanele kucatshangelwe lapho kukhethwa imitha yokugeleza efanelekile ngokusekelwe ekusetshenzisweni okusebenzayo. Ububanzi bokugeleza yinto yokuqala okufanele inqunywe ngaphambi kokukhetha ububanzi obuphelele obufanele. Amamitha okugeleza kobuningi obuncane ayathandwa ngenxa yokunemba okuphezulu uma ububanzi bokugeleza buncane. Ngaphandle kwalokho, izinga lokushisa elizungezile kanye nengcindezi kuyizinto ezengeziwe ezithonya ukunemba kokugcina. Imitha yokugeleza kobuningi ekwazi ukumelana nokushisa okuphezulu kanye nengcindezi ithatha indawo yokuqala ekwenzeni ukukhetha ukuthi izinga lokushisa kanye nengcindezi kuphakeme.
Amamitha okugeleza kobuningi beCoriolis avela eLonnmeter anikeza u-0.1% - 0.05% wokunganembi kwesilinganiso ebangeni lokugeleza kobuningi elifika ku-100:1. Ububanzi bamashubhu agobile bubanzi kunobamamitha e-tube aqondile. Iphutha eliphelele lemitha liqukethe kokubili ukunganembi kwesisekelo kanye nephutha le-zero-shift, okuwukuphuma komphumela wesignali ongavamile esimweni sokugeleza kwe-zero-shift. Iphutha le-zero-shift yisona sizathu esiyinhloko sephutha, elibalelwa ku-1%-2% wesilinganiso esilinganisiwe ngokujwayelekile.
Abanye abakhiqizi babonisa ukunemba okuphelele ngesimo sephesenti lesilinganiso sokugeleza kokugeleza okuphezulu kanye nephesenti lesilinganiso sokugeleza kanye nephutha le-zero-shift. Kubalulekile ukubuyekeza imininingwane lapho uqhathanisa ngenxa yobuqili obuhilelekile.
Izicelo kanye nemikhawulo yamamitha okugeleza kwesisindo
Amamitha okugeleza kobuningi avame ukuthonywa yizimo zemvelo, ukufundwa, ukubala; ukulungiswa kwamaphutha kungabangela umonakalo ongaba khona emishinini, ukwehla kokusebenza kahle kanye nokwehla kokunemba. Bheka izinkinga ezilandelayo ezingase zenzeke kumamitha okugeleza kobuningi:
Ingcindezi yeNombolo 1 ingase yehle uma ijubane lokugeleza likhuphuka ukuze kutholakale;
Amamitha e-Coriolis anguNombolo 2 ayabiza kakhulu kunezinye izilinganisi zokugeleza. Futhi awakwazi ukufakwa kumapayipi amakhulu.
No.3 Ukuminyana komswakama kumagesi agcwele kungadala ukufundwa okuphansi kanye nokugqwala okuhambisanayo.
Cha. 4 Ukwakheka kwesensa noma izinto eziqongelelayo kuzothinta ukusebenza kahle kokudluliselwa kokushisa.
Naphezu kwezindleko zokuqala eziphakeme, izinzuzo zesikhathi eside zokunemba, ukugcinwa okuphansi kanye nokuqina kushiya amamitha okugeleza kobuningi beCoriolis eyisisombululo esiwusizo ezimbonini eziningi. Ukulinganisa okuqondile nokuthembekile kobukhulu, ubuningi kanye nokushisa kubenza babe nokuguquguquka kusukela ku-oyili, igesi kuya ekudleni naseziphuzweni.
Sicela uzizwe ukhululekile ukuxhumana nathi futhi uthintane nochwepheshe ukuze ukhethe amamitha okugeleza kobuningi afanele uma uthola umenzi onokwethenjelwa wamamitha okugeleza kobuningi beCoriolis. Noma vele ucele ikhotheshini yamahhala enezidingo ezithile.
