Iimitha zokuhamba kwamanzi ezahlukeneyo zisebenza ekuphuculeni ukusebenza kakuhle kwenkqubo, ukuchaneka kwayo kunye nokuthembeka kwayo okuhlala ixesha elide. Kubalulekile ukujonga iinkalo ezahlukeneyo zohlobo ngalunye kunye nendlela ezisombulula ngayo iimfuno ezibalulekileyo zoshishino. Fumana uhlobo lwemitha yokuhamba kwamanzi ukuze ihlangabezane neemfuno ezithile.
Iintlobo zeeMeter zoMsinga
Imitha yokuhamba kobunzima
Aimitha yokuhamba kobunzima, eyaziwa ngokuba yi-inertial flow meter, isetyenziselwa ukulinganisa isantya sokuhamba kobunzima bolwelo oluhamba ngetyhubhu. Ubunzima bolwelo oluhamba ngaphaya kwenqaku elimiselweyo ngexesha leyunithi nganye bubizwa ngokuba yi-mass flow rate. I-mass flow meter ilinganisa ubunzima endaweni ye-volume ngexesha leyunithi nganye (umz. ii-kgs ngomzuzwana) ezithumela ngesixhobo.
Iimitha zokuhamba kweCorioliszithathwa njengezona mitha zokuhamba zichanekileyo neziphindaphindwayo okwangoku. Zithumela ulwelo kwiityhubhu ezingcangcazelayo kwaye zijonga utshintsho kwisantya solwelo. Ulwelo oludlula kwiityhubhu ezingcangcazelayo lubangela ukujijeka okanye ukuguquguquka okuncinci. Ukuguquka nokuguquguquka okunjalo kuhambelana ngokuthe ngqo namazinga okuhamba kobunzima. Iimitha zeCoriolis zisebenza kuzo zombiniumlinganiselo wobunzima kunye noxinano, ekwaziyo ukusebenzisa iindlela ezahlukeneyo zokusebenza ezifana neekhemikhali, ioyile kunye negesi. Ukusebenza kwazo okugqwesileyo ngokuchanekileyo nangokusetyenziswa ngokubanzi zezona zizathu ziphambili zokuthandwa kwazo kwiinkqubo zoshishino ezintsonkothileyo.
Uhlobo lokuthintela
Iimitha zokuhamba koxinzelelo olwahlukileyo (DP)ziye zaphuculwa ngokweemfuno zoshishino lwanamhlanje, zisala ziyindlela ethembekileyo yokujonga ukuhamba komoya kunye nokulinganisa. Umahluko woxinzelelo ulinganiswa ngokusekelwe kumgaqo wokuba ubudlelwane obuthile phakathi komahluko woxinzelelo oluveliswayo xa ulwelo luhamba kwizixhobo zokuthomalalisa kunye namazinga okuhamba komoya. Isixhobo sokuthomalalisa sisixhobo sokuthomalalisa sendawo esifakwe kwipayipi. Ezona zisetyenziswa kakhulu zeziiipleyiti ze-orifice, iimpumlokwayeiityhubhu ze-venturi,isetyenziswa kakhulu ekulinganiseni nasekulawuleni iinkqubo zoshishino.
A imitha yendawo eguquguqukayoisebenza ngokulinganisa ukuhamba kolwelo oluwela indawo yecandelo lesixhobo ukuze lutshintshe ngokuphendula ukuhamba. Isiphumo esithile esilinganiswayo sibonisa isantya. I-rotameter, umzekelo wemitha yendawo eguquguqukayo, iyafumaneka kwiindidi ezahlukeneyo zolwelo kwaye isetyenziswa rhoqo ngamanzi okanye emoyeni. Omnye umzekelo yi-orifice yendawo eguquguqukayo, apho ukuhamba kolwelo oluthumela kwi-orifice kuya kuphambukisa i-plunger efakwe i-spring-loaded tapered.
I-Inferential Flowmeter
Ii-flowmeter ye-turbineiguqula isenzo soomatshini sibe yisantya sokuhamba esinokufundwa ngumsebenzisi. njenge-gpm, i-lpm, njl. Ivili le-turbine libekwe kwindlela yomjelo wolwelo ukuze yonke intshukumo ehambahambayo ijikeleze lona. Emva koko i-fluid ehambayo ithintela iiblade ze-turbine, ivelise amandla kwi-blade kwaye ityhale i-rotor ishukume. Isantya se-turbine silingana nesantya solwelo xa isantya sokujikeleza esizinzileyo sifikelela.
I-Electromagnetic Flowmeter
Ii-flowmeter yemagnethi, kwaziwa njenge "imitha ye-mag"okanye"i-electromag", sebenzisa intsimi ye-megnetic efakwe kwityhubhu yokulinganisa, ebangela umahluko onokubakho kwi-propotion kwisantya sokuhamba ngokuthe nkqo kwimigca ye-flux. Ezi mitha zisebenza kuMthetho kaFaraday we-Electromagnetic Induction, apho intsimi yemagnethi isetyenziswa kulwelo. Emva koko izinga lokuhamba linokugqitywa yi-voltage efunyenweyo elinganisiweyo. Isisombululo esisetyenziswayo kumashishini aquka ulwelo olungcolileyo, olubolayo okanye olurhabaxa. Ngeenjongo zokuchaneka nokuqina,iimitha zokuhamba kwemagnethizihlala zisetyenziswa ekucoceni amanzi, ekusetyenzweni kweekhemikhali, kunye nasekuveliseni ukutya neziselo.
I-Animitha yokuhamba kwe-ultrasonicilinganisa isantya solwelo nge-ultrasound ukuze ibale ukuhamba komthamo. Imitha yokuhamba iyakwazi ukulinganisa isantya esiphakathi kwindlela yomqadi okhutshwayo we-ultrasound nge-transduces ze-ultrasonic. Bala umahluko kwixesha lokuhamba phakathi kweepulses ze-ultrasound ukuya okanye ngokuchasene necala lokuhamba okanye ulinganise ukutshintsha kwemvamisa ngokuxhomekeke kwi-Doppler Effect. Ukongeza kwipropathi ye-acoustic yolwelo, ubushushu, uxinano, i-viscosity kunye nee-particles ezixhonyiweyo nazo zizinto ezichaphazela i-imitha yokuhamba kwamanzi ephezulu.
Aimitha yokuhamba kwevortexIsebenza ngokomgaqo othi "von Kármán vortex", ijonga izinga lokuhamba kolwelo ngokulinganisa imvamisa yee-vortices. Ngokubanzi, imvamisa yee-vortices ilingana ngokuthe ngqo nezinga lokuhamba. Into ye-piezoelectric kwi-detector ivelisa isignali yokutshaja etshintshanayo enemvamisa efanayo neye-vortex. Emva koko isignali enjalo ihanjiswa kwi-totalizer yokuhamba ekrelekrele ukuze iqhubeke nokucutshungulwa.
Iimitha zokuhamba koomatshini
Imitha yokujika echanekileyo ilinganisa umthamo wolwelo oluhamba ngesitya esifana nebhakethi okanye i-stopwotch. Isantya sokuhamba sinokubalwa ngomlinganiselo womthamo nexesha. Ukuzalisa nokukhupha iibhakethi rhoqo kuyadingeka ngenjongo yokulinganisa ngokuqhubekayo. Iimitha zepiston, iimitha zegiya ezi-oval kunye nemitha yediski ye-nutating zonke ziyimizekelo yeemitha zokujika ezichanekileyo.
Ukususela kwiimitha zokuhamba koomatshini eziguquguqukayo ukuya kwiimitha zeCoriolis ezichanekileyo kakhulu kunye ne-ultrasonic, uhlobo ngalunye lwenzelwe ukuhlangabezana neemfuno ezithile zoshishino. Nokuba ufuna ukuphatha iigesi, ulwelo, okanye umphunga, kukho isisombululo sakho. Thatha inyathelo elilandelayo lokuphucula ukusebenza kakuhle kwenkqubo yakho ngokufuna isikhokelo seengcali.Qhagamshelana nathinamhlanje ukuze ufumane ikowuteshini yasimahla, engenazibophelelo, kwaye makhe sikuncede ufumane imitha yokuhamba egqibeleleyo yomsebenzi wakho!
