I-Coriolis Massflow Measurement
Imitha yokuhamba ubunzima beCoriolisthatha incopho yetekhnoloji kumlinganiselo wolwelo lwamashishini. Amashishini amaninzi afana ne-oyile negesi, imveliso yokutya kunye namayeza afaka ukubaluleka kokusebenza kakuhle, ukhuseleko, ukuchaneka kunye nolawulo lweendleko. Ukuqonda okungahambelaniyo kwi-flow dynamics kukwasisizathu sokuthandwa kwabo, ukulinganisa ukuhamba kobuninzi ngokuthe ngqo kunokubalo olungathanga ngqo olusekwe kuxinzelelo kunye nobushushu. Isixhobo esihambisa ufundo oluchanekileyo ngexesha lokwenyani kwimeko yemozulu ecela umngeni okanye iimeko zokusetyenzwa ayinto emfutshane yokutshintsha umdlalo, ngakumbi kumashishini atsala nzima kwizinto eziguquguqukayo.
Yintoni i-Mass Flow Meter?
Imitha yokuhamba ngobuninzi isetyenziselwa ukulinganisa izinga lokuhamba kwamanzi adlula kumbhobho ngaphandle kokuphazamisa yonke inkqubo yokuvelisa. Ilinganisa ukuthunyelwa kobuninzi ngombhobho ngexesha leyunithi. Umlinganiselo wokuqukuqela obuninzi uthathwa njengesiseko esibalulekileyo seendlela zokupheka ezininzi, uqikelelo lolungelelwaniso lwemathiriyeli, ukuhlawula kunye nokudluliselwa kogcino kumashishini anxulumeneyo. Ukuthembeka kunye nokuchaneka kubaluleke kakhulu kwizicelo ezinjalo.
Isebenza Njani Imitha yokuHamba kweMisa?
Iiteknoloji ezimbini ezahlukeneyo ezisetyenzisiweyo kumlinganiselo wobunzima zi-inertial kunye ne-thermal. Imitha yangaphambili ye-inertia yaziwa ngokuba yi-Coriolis flow meters ixhomekeke kwisiphumo se-Coriolis. I-fluids edlula kumbhobho ixhomekeke kwi-Coriolis ukukhawuleza kunye nokuqaliswa komatshini wokujikeleza okubonakalayo kumbhobho. Amandla ajikisayo aveliswe kwinkqubo yokuqukuqela kolwelo iya kuba ngumsebenzi womlinganiselo wokuhamba kobunzima obulinganisiweyo.
Kamvaimitha yokuhamba kwe-thermal massukulinganisa isantya sokuhamba kweegesi kunye nolwelo ngokuthe ngqo. Ingaba ukwazisa ubungakanani obuthile bobushushu kumjelo oqukuqelayo okanye ukugcina iprobe kwiqondo lobushushu elingaguqukiyo, imitha yokuhamba kwe-thermal mass isebenza kunye ne-sensors ezimbini zobushushu kunye ne-heater yombane. Lo mhlathi ungasentla uyachazaindlela i-thermal mass flow meter isebenza ngayo.
Uthini uMmiselo we-Mass Flow Meter?
Iimitha zokuqukuqela kobunzima zijolise ekulinganiseni ubunzima bento equkuqelayo kwindawo ethile ngexesha leyunithi nganye. Kodwa ziyahluka kwiitekhnoloji zemilinganiselo echanekileyo ekujoliswe kuyo njenge-thermal, iCoriolis, i-ultrasonic okanye i-vortex. ICoriolis mass flow meteryenye yezona zinto zithandwa kakhulu imitha yokuhamba ngokuchaneka kwayo kunye nokuthembeka.
Ukuchaneka kunye nokuHlangana kweMitha yokuHamba kweMisa
Ngenxa yokuchaneka okugqwesileyo kunye nokuphinda-phinda, iimitha zokuhamba ngobuninzi ziyathandwa kumashishini afaka ukubaluleka kokuchaneka. Ukungeniswa kweemitha zokuqukuqela kobunzima kubhekiselele kuluhlu oluphezulu abanokulinganisa. Uluhlu lwemitha yokuhamba ngobunzima luhambelana ngokungafaniyo nokungachaneki kwayo ngokubanzi. Izizathu zolo budlelwane zilele kwi-muting-sensitivity sensors ezixhotyiswe kuluhlu olubanzi lweemitha zokuqukuqela, ezingenabuntununtunu njengezo mitha zokuqukuqela ezimxinwa ezinobuntununtunu.
Ungakukhetha njani ukuRangeable okuLungileyo kweemitha eziHambayo?
Imiba efana nodidi lolwelo, uluhlu lokuhamba, ukuchaneka, ubushushu kunye noxinzelelo kufuneka zithathelwe ingqalelo xa ukhetha imitha yokuhamba kwamanzi efanelekileyo ngokusekelwe kwizicelo ezibonakalayo. Uluhlu lokuhamba yinto yokuqala ekufuneka igqitywe ngaphambi kokukhetha uluhlu olufanelekileyo lwesikali esipheleleyo. Uluhlu oluncinci lweemitha zokuhamba kobunzima zikhethwa ukuchaneka okuphezulu ukuba uluhlu lokuhamba luncinci. Ngaphandle koko, ubushushu be-ambient kunye noxinzelelo zizinto ezongezelelweyo ezichaphazela ukuchaneka kokugqibela. Imitha yokuhamba ngobuninzi ikwazi ukumelana nobushushu obuphezulu kunye noxinzelelo luthatha indawo ephambili ekwenzeni ukhetho ukuba ubushushu kunye noxinzelelo luphezulu.
Iimitha zokuqukuqela kobunzima beCoriolis ukusuka eLonnmeter zibonelela nge-0.1% - 0.05% yezinga lokungachaneki kuluhlu lokuhamba kobunzima ukuya kwi-100:1. Uluhlu lweetyhubhu ezigobileyo lubanzi kunolo lwemitha yetyhubhu ethe tye. Iphutha lilonke lemitha liquka ukungachaneki kwesiseko kunye nempazamo ye-zero-shift, ekukujika kwemveliso yesignali engaqhelekanga kwimeko yokuhamba-zero. Impazamo ye-zero-shift sesona sizathu siphambili sempazamo, ibalelwa kwi-1% -2% yomlinganiselo olinganisiweyo ngokwesiqhelo.
Abanye abavelisi babonisa ukuchaneka ngokubanzi ngendlela yepesenti yesantya sokuhamba kwamanzi aphezulu kunye nepesenti yesantya sokuhamba kunye nempazamo ye-zero-shift. Kubalulekile ukuphonononga iinkcukacha xa uthelekisa ngenxa yobuqhophololo obubandakanyekayo.
Usetyenziso kunye nokuMiselwa kweemitha zokuHamba kweMisa
Iimitha zokuhamba ngobuninzi zivame ukuphenjelelwa kukutshintsha kwemo engqongileyo, ukufundwa, ukubala; ukulungiswa kwempazamo kunokubangela umonakalo onokubakho kwisixhobo, ukunciphisa ukusebenza kakuhle kunye nokunciphisa ukuchaneka. Jonga ezi ngxaki zilandelayo zinokuthi zenzeke kwiimitha zokuqukuqela kobunzima:
No.1 Uxinzelelo lunokuhla ukuba isantya sokuhamba siyenyuka ukuze sibonwe;
No.2 Coriolis metres zibiza kakhulu kunezinye iiflow metre. Kwaye ayinakufakwa kwimibhobho emikhulu.
No.3 Ukunyuka kobumanzi kwiigesi ezigcweleyo kunokubangela ufundo oluphantsi kunye nokuhlwa okuhambelanayo.
No. 4 Ukwaleka okanye ukwakhiwa kwezinto kwi-sensor kuya kuba nefuthe ekusebenzeni kokuhanjiswa kobushushu.
Ngaphandle kweendleko zokuqala eziphezulu, iinzuzo zexesha elide zokuchaneka, ukugcinwa okuphantsi kunye nokuqina zishiya i-Coriolis mass flow metres isisombululo esinexabiso kumashishini amaninzi. Imilinganiselo ethe ngqo nethembekileyo yobunzima, ingxinano kunye nobushushu buzishiya ziguquguquka ukusuka kwi-oyile, igesi ukuya ekutyeni kunye nesiselo.
Nceda uzive ukhululekile ukuqhagamshelana nathi kwaye udibane neengcaphephe ukukhetha iimitha zokuqukuqela kobunzima obufanelekileyo ukuba ufumana umenzi othembekileyo weCoriolis mass flow meters. Okanye vele ucele ikowuti yasimahla eneemfuno ezithile.
