Ukuqonda Oko Kwenziwa Zii-Electromagnetic Flowmeters: Zeziphi Izinto Ezimanzi Ezinokulinganisa?

Ii-electromagnetic flowmeters zisetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokukwazi kwazo ukulinganisa ngokuchanekileyo ukuhamba kolwelo oluqhuba umbane. Ezi zixhobo zaziwa ngokuthembeka kwazo kunye nokuguquguquka kwazo, nto leyo ezenza zifaneleke kwiintlobo ngeentlobo zezicelo. Nangona kunjalo, umbuzo oqhelekileyo ngulo, "Luhlobo luni lolwelo olunokulinganiswa yi-electromagnetic flowmeter?"

Ukuze uphendule lo mbuzo, kubalulekile ukuqonda imigaqo esekwe kwiimitha zokuhamba kwe-electromagnetic. Ezi zixhobo zisebenza ngokusekelwe kumthetho kaFaraday wokungenisa i-electromagnetic, othi xa umqhubi edlula kwintsimi yemagnethi, i-voltage ibangelwa kwi-conductor. Nge-flowmeter ye-electromagnetic, ulwelo oluqhubayo lusebenza njengomqhubi ohambayo kwaye intsimi yemagnethi iveliswa ziikhoyili ze-flowmeter. Ngokulinganisa i-voltage ebangelwayo, i-flow meter inokumisela ngokuchanekileyo isantya sokuhamba kolwelo.

Ngenxa yalo mgaqo wokusebenza, ii-electromagnetic flowmeters zenzelwe ngokukodwa ukulinganisa ukuhamba kolwelo oluqhubayo. Oku kuthetha ukuba ulwelo kufuneka lube nenqanaba elithile lokuqhuba ukuze i-flow meter isebenze ngokufanelekileyo. Ngokubanzi, ulwelo olunokuqhuba kombane okuncinci kwe-5 µS/cm (microSiemens per centimeter) lufanelekile ukulinganiswa ngee-electromagnetic flow meters.

Imizekelo eqhelekileyo yolwelo olunokulinganiswa ngeemitha zokuhamba kwe-electromagnetic ibandakanya amanzi, ii-asidi, ii-alkali, kunye nezisombululo ezahlukeneyo zeekhemikhali. Ezi zinto zimanzi zihlala zinamanqanaba okuqhuba afunekayo ukuqinisekisa ukulinganiswa okuchanekileyo kokuhamba. Ukongeza, indlela engangeniyo yokungena kwemitha yokuhamba kwe-electromagnetic izenza zilungele ukusetyenziswa kunye nolwelo olurhabaxa okanye olubolayo kuba akukho nxalenye ishukumayo okanye izithintelo kwindlela yokuhamba enokuthi yonakale.

Kubalulekile ukuqaphela ukuba nangona iimitha zokuhamba kombane zifanelekile ukulinganisa iintlobo ngeentlobo zolwelo oluqhuba umbane, kukho imida ethile ekufuneka iqwalaselwe. Umzekelo, ulwelo olune-conductivity ephantsi kakhulu, njengeoyile ezicocekileyo okanye iihydrocarbons, lusenokungafaneleki ukulinganiswa nge-electromagnetic flowmeter. Kule meko, ezinye iindlela zokulinganisa ukuhamba kombane ezifana neemitha zokuhamba kombane ezisebenzisa i-ultrasonic okanye i-thermal mass zinokuba zifanelekile ngakumbi.

Ukongeza, ukubakho kwamaqamza okanye amasuntswana aqinileyo kulwelo kuya kuchaphazela ukuchaneka kokulinganisa kwe-electromagnetic flowmeter. Ulwelo kufuneka lugcinwe lungenamaqamza kunye nenkunkuma ukuze kufunyanwe ukufundwa kokuhamba okuthembekileyo.

Ngamafutshane, iimitha zokuhamba kombane ziyakwazi ukulinganisa iintlobo ngeentlobo zolwelo oluqhubayo, kuquka amanzi, ii-asidi, ii-alkali, kunye nezisombululo zeekhemikhali. Uyilo lwazo olungaphazamisiyo kunye nokuchaneka okuphezulu kuzenza zibe lukhetho oludumileyo lokulinganisa ukuhamba kwamanzi kumashishini afana nonyango lwamanzi, ukucubungula iikhemikhali, kunye nokuveliswa kokutya neziselo. Nangona kunjalo, kubalulekile ukuqwalasela ukuhanjiswa kombane kunye nokucoceka kolwelo ukuqinisekisa ukusebenza kakuhle kwemitha yokuhamba kombane. Ngokuqonda amandla kunye nemida yemitha yokuhamba kombane, abasebenzisi banokwenza isigqibo esinolwazi malunga nokufaneleka kwabo kwisicelo esithile sokulinganisa ulwelo.
