I-Thermal Mass Flow Meter uhlobo lwethuluzi lokulinganisa ukugeleza elisetshenziselwa ukukala izinga lokugeleza kwesisindo samagesi. Ngokungafani namamitha okugeleza endabuko alinganisa ukugeleza kwevolumu, imitha yokugeleza kwesisindo sokushisa ilinganisa ngqo ukugeleza kwesisindo soketshezi, okwenza kube usizo ikakhulukazi ekusetshenzisweni lapho ukuguquguquka kwezinga lokushisa kanye nengcindezi kungathinta ukunemba kokulinganisa kwevolumu.
Imitha yokugeleza kwesisindo sokushisa isebenza ngokusekelwe esimisweni sokudluliselwa kokushisa. Isebenzisa iqiniso lokuthi izinga lokudluliselwa kokushisa kusuka entweni efudumele kuya kugesi ezungezile lilingana nezinga lokugeleza kwesisindo segesi.
Kusebenza Kanjani?
1. Isici Sokushisa:
Imitha yokugeleza inenzwa efudumele (noma isici) esibekwe emgudwini wokugeleza kwegesi. Inzwa ngokuvamile iyisici esincane sensimbi esishiswa ngogesi kuze kufike ezingeni lokushisa elaziwayo.
2. Umehluko Wezinga Lokushisa:
Njengoba igesi idlula phezu kwento efudumele, igesi imunca ukushisa. Izinga lokushisa lenzwa efudumele liyancipha njengoba ukushisa kudluliselwa kugesi. Inani lokushintsha kwezinga lokushisa kunzwa lincike esilinganisweni sokugeleza kwesisindo segesi.
3. Ukudluliselwa Kokushisa Ngokwesilinganiso Sezinga Lokugeleza:
Uma igesi igeleza kakhulu phezu kwenzwa, kulapho ukushisa okudluliswayo kukhulu khona, ngakho-ke, izinga lokushisa lenzwa lizokwehla kakhulu. Lokhu kungenxa yokuthi ama-molecule egesi asusa ukushisa okwengeziwe uma ehamba ngokushesha (okungukuthi, lapho izinga lokugeleza kobuningi liphezulu).
4. Ukulinganisa kanye nokubala:
Imitha yokugeleza ilinganisa umehluko wokushisa phakathi kwento efudumele kanye nokushisa okubhekiselwe kukho (ngokuvamile kulinganiswa ngenzwa yesibili). Kusukela kulo mehluko wokushisa, imitha yokugeleza ibala izinga lokugeleza kwesisindo segesi ngokusekelwe kuma-calibiration curves noma ama-algorithms achazwe ngaphambilini.
Izingxenye Eziyinhloko Zemitha Yokugeleza Kwesisindo Sokushisa:
1. Isici Sokuzwa (I-Thermistor noma i-RTD):
Lena yingxenye yemitha efudunyezwayo futhi izinga lokushisa layo liqashwe ukuze kutholakale izinga lokugeleza kobuningi.
2. Umthombo Wokushisa:
Isici esincane sokushisa sikagesi esihlinzeka ngokushisa ku-sensor.
3. Inzwa Yokugeleza (noma I-Probe):
I-probe ibekwe emgudwini wegesi futhi iqukethe izinzwa ezilinganisa umehluko wokushisa kanye nezimo zokugeleza.
4. Iprosesa encane:
Iprosesa ibala izinga lokugeleza kwesisindo ngokusekelwe ezinguqukweni zokushisa ezitholwe yizinzwa.
Izinhlobo Zamamitha Okugeleza Kwesisindo Esishisayo:
1. Amamitha Okugeleza Anephuzu Elilodwa:
Lawa mamitha anenzwa eyodwa eshisayo kanye nenzwa eyodwa yokushisa. Ukugeleza kobuningi kunqunywa umehluko wokushisa phakathi kwenzwa eshisayo kanye nenzwa yokubhekisela.
Lokhu kuvame ukusetshenziselwa amazinga okugeleza aphansi kanye namagesi anezakhiwo ezilinganayo.
2. Amamitha Okugeleza Amaphuzu Amabili noma Amaphuzu Amaningi:
Lawa mamitha asebenzisa izinzwa eziningi zokushisa, ezingavumela ukulinganisa okunembe kakhulu kuzo zonke izinhlobo eziningi zamazinga okugeleza kanye namagesi.
Imiklamo ethuthukisiwe kakhulu ithuthukisa ukunemba ngokunxephezela ukushintshashintsha kwezinga lokushisa kanye nezakhiwo zegesi endleleni yokulinganisa.
Izinzuzo zama-Thermal Mass Flow Meters:
1. Ukulinganisa Ukugeleza Kwesisindo Okuqondile:
Ngokungafani namamitha okugeleza evolumu (njengepuleti le-orifice noma amamitha e-turbine), amamitha okugeleza kwesisindo sokushisa alinganisa ukugeleza kwesisindo ngqo, ngaphandle kokushintshashintsha kwezinga lokushisa noma kwengcindezi. Lokhu kubalulekile ekusetshenzisweni lapho lezi zici zingazinzile noma zihluka kakhulu.
2. Izingxenye Ezingashukumi:
Amamitha okugeleza kokushisa ngokuvamile awanazo izingxenye ezihambayo, okusho ukuthi adinga ukulungiswa okuncane, awagugi kakhulu, futhi angasebenza ezindaweni ezinzima noma ezigqwalisayo.
3. Ukunemba Ekulinganisweni Kwegesi:
Zinembile kakhulu ekulinganiseni ukugeleza kwesisindo samagesi futhi zisebenza kahle ngisho noma amazinga okugeleza ephansi. Zingalinganisa uhla olubanzi lwamagesi, okuhlanganisa umoya, i-nitrogen, i-oxygen, kanye namanye amagesi ezimboni.
4. Incane futhi kulula ukuyifaka:
Lawa mamitha avame ukuba mancane futhi kulula ukuwafaka uma kuqhathaniswa nezinye izindlela zokulinganisa ukugeleza kobuningi.
5. Ukwehla Kokucindezela Okuphansi:
Njengoba imitha ingenazo izithiyo njengezingxenye zemishini, ngokuvamile idala ukwehla kwengcindezi okuphansi kakhulu kudivayisi, okuzuzisayo ekugcineni ukusebenza kahle kwesistimu.
Ukusetshenziswa Kwamamitha Okugeleza Kwesisindo Esishisayo:
1. Amagesi Ezimboni:
Amamitha okugeleza kobuningi bokushisa asetshenziswa kabanzi ezimbonini ezibhekene namagesi, njengokucubungula amakhemikhali, izitshalo ze-petrochemical, ukukhiqizwa kwemithi, kanye nokukhiqizwa kokudla neziphuzo.
2. Izinhlelo ze-HVAC:
Ezinhlelweni zokushisa, ukungenisa umoya, kanye ne-air conditioner (HVAC), lawa mamitha asetshenziselwa ukuqapha amazinga okugeleza komoya ukuze kulawulwe izinhlelo kanye nokuqinisekisa ukusetshenziswa kwamandla okuphumelelayo.
3. Amandla Nezinsizakusebenza:
Ukuze kulinganiswe ukugeleza komoya ocindezelwe, i-nitrogen, i-oxygen, kanye namanye amagesi ezimboni ezitshalweni zikagesi, izikhungo zokukhiqiza amandla, kanye nezinsiza.
4. Ukuqapha Imvelo:
Amamitha okugeleza kobuningi bokushisa nawo asetshenziswa ezindleleni zemvelo ukuqapha ukukhishwa kwentuthu noma izinhlelo zokukhipha umoya ukuze kuqinisekiswe ukuthi kulandelwa imithethonqubo yezemvelo.
5. Izimoto kanye nezindiza:
Lawa mamitha asetshenziswa ezinhlotsheni lapho kudingeka khona ukulawulwa okunembile kokugeleza kwegesi, njengasekuhlolweni kokukhishwa kwegesi emotweni noma ezindaweni zezindiza lapho ukulawulwa okunembile kokugeleza kubalulekile khona.
6. Imboni Yezikhombisi-ndlela:
Amamitha okugeleza kwesisindo sokushisa angasetshenziswa ekulinganisweni okunembile kokugeleza kwegesi ezinqubweni ezifana nokufakwa komphunga wamakhemikhali (i-CVD) noma ukuqopha, lapho ukulawulwa okuqondile kokugeleza kwegesi kubalulekile.
Imikhawulo Yamamitha Okugeleza Kwesisindo Esishisayo:
1. Ukuxhomekeka Kokwakheka Kwegesi:
Ukusebenza kwamamitha okugeleza kwesisindo sokushisa kuthinta ukushisa okuthile kanye nokuqhuba kokushisa kwegesi elinganiswayo. Ukulinganisa kuyadingeka kumagesi ahlukene, futhi imitha ingadinga ukulungiswa uma ukwakheka kwegesi kushintsha.
2. Ukusetshenziswa Okulinganiselwe Noketshezi:
Amamitha okugeleza kobuningi bokushisa ngokuvamile asetshenziselwa amagesi futhi awafaneleki uketshezi noma ama-slurry, njengoba izakhiwo zokudlulisa ukushisa koketshezi zihluke kakhulu kumagesi.
3. Ukuzwela Kwephrofayili Yokugeleza:
Lawa mamitha angase athintwe amaphrofayili okugeleza angafaneleki (isb., ukugeleza okujikelezayo noma okuguquguqukayo) uma inzwa ingafakwanga kahle noma uma izimo zokugeleza zingalingani.
4. Ukushisa Nokuzwela Ukucindezeleka:
Nakuba amamitha okugeleza kwesisindo sokushisa aklanyelwe ukuba angazweli kakhulu ezinguqukweni zokushisa kanye nengcindezi uma kuqhathaniswa namamitha omthamo, ukuguquguquka okukhulu kusengathinta ukunemba kokulinganisa, ikakhulukazi uma izakhiwo zegesi zishintsha kakhulu.
Isiphetho:
I-Thermal Mass Flow Meter iyisinqumo esihle kakhulu sokulinganisa ukugeleza kwesisindo samagesi, ikakhulukazi lapho izimo zokushisa nengcindezi zishintshashintsha, noma lapho udinga ukulinganiswa okunembile kokugeleza kwesisindo kudivayisi encane, engadingi ukulungiswa okuningi. Isetshenziswa kabanzi ezimbonini ezifana nokucubungula amakhemikhali, i-HVAC, kanye namandla, lapho ukulawulwa okunembile nokuqapha ukugeleza kwegesi kubalulekile ekusebenzeni kahle kwesistimu.
Uma isicelo sakho sihilela ukulinganisa amagesi anokushisa nokucindezela okuhlukahlukene, imitha yokugeleza kwesisindo sokushisa ingaba yisisombululo esifanele. Kodwa-ke, ukuqonda ukwakheka kwegesi nokuqinisekisa ukuthi imitha ilinganiswe kahle kubalulekile ekutholeni ukusebenza okuhle kakhulu kulobu buchwepheshe.
