Kuyerwa kweCoriolis Mass Flow
Miyero yekuyerera kweCoriolis massNdiyo inonyanya kukosha pakuongorora mvura inoshandiswa mumaindasitiri. Maindasitiri mazhinji akadai semafuta negesi, kugadzira chikafu nemishonga anoona kukosha kwekushanda zvakanaka, kuchengetedzeka, kunyatsojeka uye kudzora mutengo. Kunzwisisa kwakasiyana-siyana kwemafambiro emvura ndicho chikonzero chekuzivikanwa kwavo, kuyera kuyerera kwemvura zvakananga pane kuverenga zvisina kunanga zvichibva pakumanikidzwa nekupisa. Mudziyo unoita kuverenga kwakarurama munguva chaiyo mumamiriro ekunze akaoma kana mamiriro ekugadzirisa zvinhu unochinja-chinja zvinhu, kunyanya kumaindasitiri ari kutambudzika mumamiriro ezvinhu akaoma.
Chii chinonzi Mass Flow Meter?
Chiyero chekuyerera kwehuwandu chinoshandiswa kuyera mwero wekuyerera kwemvura inopfuura nemupombi pasina kukanganisa maitiro ese ekugadzira. Chinoyera huwandu hwemvura inotumirwa nemupombi panguva imwe neimwe. Kuyera huwandu hwemvura inoyerera kunoonekwa sehwaro hwakakosha hwemaresipi mazhinji, kusarudza huwandu hwezvinhu, kubhadhara pamwe nekuchinjisa kuchengetedza muindasitiri dzakabatana. Kuvimbika uye kururama ndiko kwakakosha mukushandiswa kwakadaro.
Chiyero cheMass Flow Meter Chinoshanda Sei?
Matekinoroji maviri akasiyana anoshandiswa pakuyera huremu ndeanoti inertial uye thermal. Iyo yekare inertia meter inozivikanwa seCoriolis flow metres zvichienderana neCoriolis effect. Mvura inopfuura nemupombi inowedzerwa nekukasira kweCoriolis nekupinza kwemuchina kwekutenderera kunoonekwa mupombi. Simba rinotsausa rinogadzirwa mukuyerera kwemvura richava basa rekuyerwa kwehuwandu hwekuyerera kwemvura.
Iyo gare garemita yekuyerera kwemafuta ekupisakuyera mwero wekuyerera kwemagasi nezvinwiwa zvakananga. Kungave kuisa huwandu hwakati hwekupisa murwizi runoyerera kana kuchengetedza probe patembiricha yakaenzana, thermal mass flow meter inoshanda nemasensa maviri ekupisa uye heater yemagetsi. Ndima iri pamusoro inotsananguramashandiro anoita mita yekuyerera kwemafuta ekupisa.
Chii chinonzi Nheyo yeMita yeMass Flow?
Mamita ekuyerera kwemasero anovavarira kuyera huremu hwechinhu chinoyerera nepakati pechinhu chakapihwa panguva imwe neimwe. Asi anosiyana mumatekinoroji ekuyera kwakanangana nekupisa, Coriolis, ultrasonic kana vortex.Chiyero chekuyerera kwehuwandu hweCoriolisndeimwe yemichina yekuyera mvura inoyerera inozivikanwa zvikuru nekuda kwekururama kwayo uye kuvimbika kwayo.
Kururama & Kugona Kufamba Kwemamita Ekufamba KweMisa
Nekuda kwekururama kwayo kukuru uye kudzokorora kwayo, mita dzekuyerera kwehuwandu dzinofarirwa mumaindasitiri anokoshesa kurongeka. Kugona kutenderera kwemamita ekuyerera kwehuwandu zvinoreva huwandu hwepamusoro hwavanogona kuyera. Hurefu hwemita yekuyerera kwehuwandu hunoenderana nekusarongeka kwayo kazhinji. Zvikonzero zvehukama hwakadaro zviri mumasensa ekuti muting-sensitivity akashongedzerwa mumamita ekuyerera kwehuwandu hwakakura, ayo asina kugadzikana seaya mamita ekuyerera kwehuwandu akamanikana ane hypersensitivity.
Ungasarudza Sei Kukwanisa Kuyerera Kwema Flow Meters Kwakakodzera?
Zvinhu zvakaita semhando yemvura, huwandu hwemvura inoyerera, kururama, tembiricha uye kumanikidzwa zvinofanirwa kutariswa pakusarudza mita yekuyerera yakakodzera zvichibva pakushandiswa kwayo. Kuwanda kwemvura ndicho chinhu chekutanga chinofanira kutariswa usati wasarudza huwandu hwakakodzera hwemvura inoyerera. Mita yekuyerera kwemvura yemhando diki inofarirwa kuti ive yakanyatsojeka kana huwandu hwemvura inoyerera hudiki. Kunze kweizvozvo, tembiricha yemhepo nekumanikidzwa zvimwe zvinhu zvinopesvedzera kururama kwekupedzisira. Mita yekuyerera kwemvura yemhando yepamusoro inokwanisa kumira tembiricha yakakwira nekumanikidzwa ndiyo inonyanya kukosha pakusarudza kana tembiricha nekumanikidzwa kwakakwira.
Mita dzekuyerera kweCoriolis mass kubva kuLonnmeter dzinopa 0.1% - 0.05% yekusarongeka kwehuwandu hwemvura inoyerera kusvika ku100:1. Kugona kwematanho ekutenderera kwakafara kupfuura mita dzemachubhu akatwasuka. Kukanganisa kwese kwemita kunosanganisira kusarongeka kwebase uye zero-shift error, inova ndiyo turnout yechiratidzo chisina kujairika mumamiriro e zero-flow. Kukanganisa kwe zero-shift ndicho chikonzero chikuru chekukanganisa, zvichiita 1%-2% yehuwandu hwakayerwa muzvakajairika.
Vamwe vagadziri vanoratidza kururama kwese muchimiro chehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu pamwe nekukanganisa kwe zero-shift. Zvakakosha kuongorora zvirevo pakuenzanisa nekuda kwehunyengeri hunobatanidzwa.
Mashandisirwo & Miganhu yeMamita Ekuyerera Kwemisa
Mita dzemagetsi dzinoshandiswa pakuongorora huwandu hwezvinhu (mass flow meter) dzinogona kukanganiswa nezvinhu zvakasiyana-siyana, kuverenga, kuverenga; kugadzirisa zvikanganiso kunogona kukonzera kukuvara kwemidziyo, kudzikira kwekushanda zvakanaka uye kudzikira kwekunyatsorongeka. Tarisa matambudziko anotevera anogona kuitika pamita dzemagetsi dzinoshandisa huwandu hwezvinhu:
Nhamba 1 Kumanikidzwa kunogona kuderera kana kumhanya kwekuyerera kukawedzera kuti zvionekwe;
Nhamba 2 yeCoriolis metres inodhura kupfuura mamwe maflowmeter. Uye haagone kuiswa pamapombi makuru.
Nhamba 3 Kunyorova kwemvura mumagasi akazara kunogona kukonzera kuverenga kwakaderera uye ngura inoenderana.
Nhamba 4 Kuputira kana kuunganidza zvinhu pa sensor kunokanganisa kushanda zvakanaka kwekutamisa kupisa.
Pasinei nemutengo wakakwira wekutanga, mabhenefiti enguva refu ekururama, kusachengetedza kwakaderera uye kugara kwenguva refu kunoita kuti Coriolis mass flow meter ive mhinduro yakanaka mumaindasitiri mazhinji. Kuyera kwakananga uye kwakavimbika kwehukuru, huwandu uye tembiricha kunoita kuti zvive zvakasiyana-siyana kubva pamafuta, gasi kusvika kuchikafu nezvinwiwa.
Ndapota inzwa wakasununguka kutibata uye kubvunza nyanzvi kuti tisarudze mita yekuyerera kwehuwandu yakakodzera kana uri kuwana mugadziri akavimbika weCoriolis mass flow metres. Kana kungokumbira mutengo wemahara une zvinodiwa chaizvo.
