Ii-Electromagnetic Flowmeters: Ukuchaneka kunye nokuguquguquka kwiSilinganiselo sokuhamba kwanamhlanje

Ii-electromagnetic flowmeters, ezidla ngokubizwa ngokuba zii-"magmeters," ziye zaguqula umlinganiselo wolwelo kumashishini ngokusebenzisa uMthetho kaFaraday wokungeniswa kwe-electromagnetic ukuze kubonelelwe ngedatha yokuhamba echanekileyo, engaphazamisiyo. Ngokungafaniyo nokuxhomekeka kwazo kwiteknoloji enzima, ezi zixhobo zibonelela ngeenzuzo ezikhethekileyo ekuphatheni ulwelo olunzima—ukusuka kwiikhemikhali ezibolayo ukuya kwi-slurry—okwenza ukuba zibe yimfuneko kumacandelo afana nonyango lwamanzi, ukucubungula iikhemikhali, kunye nemveliso yokutya.

Indlela ii-Electromagnetic Flowmeters ezisebenza ngayo

• Umbhobho ongengowemagnethi ogqunywe ngezinto zokukhusela ubushushu (ukuthintela ukuphazamiseka kombane).
• Iikhoyili ezimbini ze-electromagnetic ezidala intsimi yemagnethi kumbhobho.
• Ii-electrodes zifakelwe kumacala ahlukeneyo ombhobho ukuze zibone i-voltage ebangelwayo.
• Isixhobo sokudlulisa esiguqula le voltage ibe yireyithi yokufunda ukuhamba kwamanzi.

Iingenelo eziphambili kwizicelo zoshishino

1. Ukuchaneka Kwiimeko Ezihlukeneyo: Zigcina ukuchaneka (ngesiqhelo ±0.5% yokufundwa) nokuba ubuninzi bolwelo, uburhabaxa, okanye ubushushu bunjani—oko kuzenza zilungele ulwelo olufana nodaka, olutshintshatshintshayo ngokufana.
2. Uyilo Olungaphazamisiyo: Ekubeni kungekho zinto zangaphakathi eziphumayo kumsinga, ii-magmeter ziphepha ukuhla koxinzelelo, ukuvaleka, okanye umonakalo ovela kumasuntswana arhabaxa (umz., kwimigodi). Oku kunciphisa ukugcinwa kwaye kwandisa ubomi benkonzo.
3. Ukuguquguquka kwiintlobo zolwelo: Ziphatha ulwelo oluqhubayo (kuquka amanzi, ii-asidi, kunye namanzi amdaka) kwaye zisebenza nolwelo olucocekileyo ekuveliseni ukutya/iziselo, ngenxa yee-liners ezigudileyo nezilula ukuzicoca (umz., i-PTFE).
4. Ukulinganisa iMigqaliselo emibini: Ngokungafaniyo nezinye ii-flowmeter, ii-magmeter zilinganisa ngokuchanekileyo ukuhamba kwamanzi kuzo zombini iindlela—ezixabisekileyo kwiinkqubo ezinokuhamba okungasemva, ezifana neenethiwekhi zokusasaza amanzi.

Izicelo zeHlabathi lokwenyani

• Amanzi kunye namanzi amdaka: Asetyenziselwa ukujonga ukungena kwamanzi angavuthwanga, ukunyanga ukuhamba kwamanzi amdaka, kunye nokubona ukuvuza kwiinkqubo zokusasaza.
• Ukucubungula iikhemikhali: Linganisa ulwelo olubolayo okanye olunetyhefu (umz., ii-asidi, ii-alkali) ngaphandle komngcipheko wokungcola okanye umonakalo wemitha.
• Ukutya Neziselo: Iimodeli zococeko ezinee-liner ezivunyiweyo yi-FDA zilandelela ukuhamba kwemveliso yobisi, ijusi, okanye ibhiya, ziqinisekisa ucoceko kunye nokuthotyelwa kwemithetho.
• Ukumba: Ukuphatha ukuhamba kodaka oluneziqina (umz., amasuntswana esinyithi), apho iimitha zoomatshini ziya kuphelelwa ngokukhawuleza.

Izinto ekufuneka ziqwalaselwe xa kuphunyezwa

• Zifuna ukuba ulwelo lube luqhuba umbane (≥5 ¥S/cm), nto leyo ethetha ukuba akufanele zisetyenziswe neeoyile okanye iigesi.
• Ukufakelwa ngokufanelekileyo (umz., ukuqinisekisa ukuhamba kombhobho ngokupheleleyo, ukuphepha izakhiwo zesinyithi ezikufutshane) kubalulekile ukuze kuthintelwe ukuphazamiseka kwemagnethi.
• Iindleko zokuqala ziphezulu kuneemitha zoomatshini, nangona iimfuno zokulungisa eziphantsi zihlala zilungisa oku ngokuhamba kwexesha.
