Umlinganiselo wokuhamba kobunzima beCoriolis
Iimitha zokuhamba kobunzima beCoriolisIthekhnoloji ithatha incopho yokulinganisa ulwelo lwemizi-mveliso. Amashishini amaninzi afana neoyile negesi, imveliso yokutya kunye namayeza agxininisa ukubaluleka kokusebenza kakuhle, ukhuseleko, ukuchaneka kunye nolawulo lweendleko. Ingqiqo engalinganiyo malunga nokuhamba kwamanzi nayo yimbangela yokuthandwa kwawo, ukulinganisa ukuhamba kobuninzi ngokuthe ngqo kunokubala ngokungathanga ngqo ngokusekelwe kuxinzelelo kunye nobushushu. Isixhobo esinikezela ngokufundwa okuchanekileyo ngexesha langempela kwiimeko zemozulu ezinzima okanye zokucubungula asinto ingaqhelekanga, ingakumbi kumashishini asokola kwiinguqu ezinzima.
Yintoni iMass Flow Meter?
Isixhobo sokulinganisa ukuhamba kobunzima sisetyenziselwa ukulinganisa isantya sokuhamba kolwelo oludlula kumbhobho ngaphandle kokuphazamisa yonke inkqubo yokwenziwa. Silinganisa ukuthunyelwa kobunzima ngepayipi ngexesha ngalinye. Ukulinganiswa kokuhamba kobunzima kuthathwa njengesiseko esibalulekileyo kwiindlela ezininzi zokupheka, ukumisela ibhalansi yezinto, ukuhlawulisa kunye nokudluliselwa kokugcinwa kwimizi-mveliso enxulumene noko. Ukuthembeka nokuchaneka kubaluleke kakhulu kwezo zicelo.
Isebenza njani iMass Flow Meter?
Iiteknoloji ezimbini ezahlukeneyo ezisetyenziswayo ekulinganiseni ubunzima yi-inertial kunye ne-thermal. I-inertia meter yangaphambili yaziwa ngokuba yi-Coriolis flow meters exhomekeke kwi-Coriolis effect. Ulwelo oludlula kumbhobho luchaphazeleka yi-Coriolis acceleration ngokungeniswa koomatshini kokujikeleza okubonakalayo kumbhobho. Amandla okuphambuka aveliswa kwinkqubo yokuhamba kolwelo aya kuba ngumsebenzi wesantya sokuhamba kobunzima esilinganisiweyo.
Kamvaimitha yokuhamba kobunzima bobushushulinganisa isantya sokuhamba kweegesi kunye nolwelo ngokuthe ngqo. Nokuba kungeniswa ubushushu obuthile kumjelo ohambayo okanye kugcinwa iprobe kubushushu obungaguqukiyo, imitha yokuhamba kobunzima bobushushu isebenza ngee-sensors ezimbini zobushushu kunye ne-heater yombane. Isiqendu esingentla sichazaindlela esebenza ngayo imitha yokuhamba kobunzima bobushushu.
Yintoni iMilinganiselo yeMitha yokuHamba koMzimba?
Iimitha zokuhamba kobunzima zijolise ekulinganiseni ubunzima bento ehamba kwindawo ethile ngexesha leyunithi nganye. Kodwa ziyahluka kwiiteknoloji zokulinganisa ngokuchanekileyo okujoliswe kuzo njenge-thermal, i-Coriolis, i-ultrasonic okanye i-vortex.Imitha yokuhamba kobunzima beCoriolisyenye yezona zixhobo zokulinganisa ukuhamba kwamanzi ezidumileyo ngenxa yokuchaneka kwayo nokuthembeka kwayo.
Ukuchaneka kunye nokuguquguquka kweeMitha zoMbane
Ngenxa yokuchaneka okugqwesileyo kunye nokuphindaphinda, iimitha zokuhamba kobunzima ziyathandwa kumashishini agxininisa ukubaluleka kokuchaneka. Ububanzi beemitha zokuhamba kobunzima bubhekisa kububanzi obuphezulu abanokubulinganisa. Uluhlu lweemitha zokuhamba kobunzima luhambelana ngokuphambeneyo nokungachaneki kwayo ngokubanzi. Izizathu zobudlelwane obunjalo zikwiinzwa zokuvaleka komsindo ezixhotyiswe kwiimitha zokuhamba kobubanzi, ezingengobukrelekrele njengezo mitha zokuhamba kobubanzi obumxinwa ezine-hypersensitivity.
Ungayikhetha njani i-Rangeability efanelekileyo yee-Flow Meters?
Izinto ezifana nohlobo lolwelo, uluhlu lokuhamba, ukuchaneka, ubushushu kunye noxinzelelo kufuneka ziqwalaselwe xa kukhethwa imitha yokuhamba efanelekileyo ngokusekelwe kwizicelo ezisebenzayo. Uluhlu lokuhamba yinto yokuqala ekufuneka imiselwe ngaphambi kokukhetha uluhlu olupheleleyo olufanelekileyo. Iimitha zokuhamba kobunzima obuncinci zikhethwa ukuze kubekho ukuchaneka okuphezulu ukuba uluhlu lokuhamba luncinci. Ngaphandle koko, ubushushu obuphakathi kunye noxinzelelo zizinto ezongezelelweyo ezichaphazela ukuchaneka kokugqibela. Imitha yokuhamba kobunzima ekwaziyo ukumelana nobushushu obuphezulu kunye noxinzelelo ithatha indawo ephambili ekwenzeni ukhetho lokuba ubushushu kunye noxinzelelo buphezulu.
Iimitha zokuhamba kobunzima beCoriolis ezivela eLonnmeter zibonelela nge-0.1% - 0.05% yokungachaneki kwesantya kuluhlu lokuhamba kobunzima ukuya kuthi ga kwi-100:1. Ububanzi beetyhubhu ezigobileyo bubanzi kunobo beemitha zetyhubhu ezithe tye. Impazamo iyonke yemitha ibandakanya ukungachaneki kwesiseko kunye nempazamo ye-zero-shift, ekukuphuma kwesiphumo sesignali esingaqhelekanga kwimeko ye-zero-flow. Impazamo ye-zero-shift sesona sizathu siphambili sempazamo, ebalelwa kwi-1%-2% yesantya esilinganisiweyo ngokwesiqhelo.
Abanye abavelisi babonisa ukuchaneka ngokubanzi ngendlela yepesenti yesantya sokuhamba kwamanzi xa kuphuma amanzi amaninzi kunye nepesenti yesantya sokuhamba kwamanzi kunye nempazamo ye-zero-shift. Kubalulekile ukuphonononga iinkcukacha xa uthelekisa ngenxa yeqhinga elibandakanyekayo.
Izicelo kunye nemida yeeMeter zokuhamba koMbane
Iimitha zokuhamba kobunzima zidla ngokuchaphazeleka ziinguqu ezingqongileyo, ukufundwa, ukubala; ukulungiswa kweempazamo kunokubangela umonakalo onokubakho kwizixhobo, ukwehla kokusebenza kakuhle kunye nokuncipha kokuchaneka. Jonga ezi ngxaki zilandelayo ezinokwenzeka kwiimitha zokuhamba kobunzima:
Inombolo 1 Uxinzelelo lunokwehla ukuba isantya sokuhamba siyanda ukuze kufunyanwe;
Iimitha zeCoriolis zeNombolo 2 zibiza kakhulu kunezinye iimitha zokuhamba kwamanzi. Kwaye azinakusetyenziswa kwiipayipi ezinkulu.
Inombolo 3 Ukufuma okufumayo kwiigesi ezigcweleyo kunokubangela ukufundwa okuphantsi kunye nokubola okuhambelanayo.
Inombolo 4 Ukwaleka okanye ukwakheka kwezinto kwisensor kuya kuchaphazela ukusebenza kakuhle kokudluliselwa kobushushu.
Nangona iindleko zokuqala ziphezulu, iingenelo zexesha elide zokuchaneka, ukugcinwa okuphantsi kunye nokuqina kushiya iimitha zokuhamba kobunzima beCoriolis isisombululo esifanelekileyo kumashishini amaninzi. Ukulinganiswa ngokuthe ngqo nangokuthembekileyo kobunzima, uxinano kunye nobushushu kuzishiya ziguquguqukayo ukusuka kwioyile, igesi ukuya ekutyeni naseziseloni.
Nceda uzive ukhululekile ukuqhagamshelana nathi kwaye udibane neengcali ukuze ukhethe iimitha zokuhamba kobunzima ezifanelekileyo ukuba ufumana umenzi othembekileyo weemitha zokuhamba kobunzima beCoriolis. Okanye ucele nje ikowuteshini yasimahla eneemfuno ezithile.
