Ukukhethwa kwesicelo se-electromagnetic flowmeter embonini yokukhiqiza ukudla
2022-07-26
Ama-flowmeters we-electromagnetic ngokuvamile asetshenziswa kuma-flowmeters embonini yokudla, asetshenziswa kakhulu ukukala ukugeleza kwevolumu yoketshezi oluqhubayo nama-slurries kumapayipi avaliwe, okuhlanganisa uketshezi olubolayo njengama-asidi, ama-alkali, nosawoti.
Ukusebenza kwe-Flowmeter kwezicelo zemboni yokudla kufanele kube nezici ezilandelayo:
1. Ukulinganisa akuthintwa izinguquko ku-fluid density, viscosity, izinga lokushisa, ingcindezi kanye ne-conductivity, 2. Azikho izingxenye zokugeleza ezivimbekile eshubhuni yokulinganisa.
3. Akukho ukulahlekelwa kwengcindezi, izidingo eziphansi zezigaba zamapayipi aqondile,
4. Isiguquli samukela indlela yenoveli evusa amadlingozi, esebenzisa amandla aphansi kanye nokuzinza okuphezulu kwamaphuzu ayiziro.
5. Ibanga lokugeleza kokulinganisa likhulu, futhi i-flowmeter iyisistimu yokulinganisa kabili, enenani eliya phambili, ingqikithi ehlehlayo kanye nengqikithi yomehluko, futhi kufanele ibe nokuphumayo okuningi.
Lapho ukhetha i-flowmeter ka-electromagnetic, qala ngokuqinisekisa ukuthi indawo yokulinganisa iyaqhuba yini. Izinga lokugeleza kwendawo elinganisiwe kuma-flowmeters we-electromagnetic ejwayelekile yemboni kungcono ukuthi kube ngu-2 kuya ku-4m/s. Ezimweni ezikhethekile, izinga lokugeleza eliphansi akufanele libe ngaphansi kuka-0.2m/s. Iqukethe izinhlayiya eziqinile, futhi izinga lokugeleza elivamile kufanele libe ngaphansi kuka-3m/s ukuvimbela ukungqubuzana okukhulu phakathi kolwelwesi kanye ne-electrode. Ngamanzi e-viscous, izinga lokugeleza elikhulu lisiza ukuqeda ngokuzenzakalelayo umphumela wezinto ezibonakalayo ezixhunywe ku-electrode, okuzuzisa ukuthuthukisa ukunemba kokulinganisa. Sebenzisa. Ngokuvamile, ububanzi obujwayelekile bepayipi lenqubo bukhethiwe. Yiqiniso, ububanzi bokugeleza koketshezi epayipini kufanele kucatshangelwe ngesikhathi esifanayo. Uma izinga lokugeleza lilincane kakhulu noma likhulu kakhulu, ububanzi bokulinganisa be-flowmeter kufanele bukhethwe ngokubhekisela kububanzi bokugeleza ngaphansi kwesisekelo sokuqinisekisa ukunemba kokulinganisa. Siyakwamukela ukuthintana nezingcweti zethu ukuze uthole ukwesekwa okuningiliziwe kokukhetha.
