Iimitha zokuhamba kwe-electromagneticzisetyenziswa kakhulu ekulinganisweni kokuhamba kwamanzi kwimizi-mveliso ngenxa yokuchaneka kwazo okuphezulu, ukugcinwa kwazo okuncinci, kunye nokungabikho kweendawo ezihambayo. Nangona kunjalo, azifanelekanga kuzo zonke izicelo. Kweli nqaku, siza kuxoxa ngeemeko apho iimitha zokuhamba kwamanzi ze-electromagnetic zisenokungabi lolona khetho lufanelekileyo, okukunceda ukhethe isixhobo sokulinganisa ukuhamba kwamanzi esifanelekileyo.
1. Ulwelo oluLinganisiweyo kufuneka luqhube kakuhle
Iimitha zokuhamba kwe-electromagnetic zisebenza ngokusekelwe kuMthetho kaFaraday wokungenisa, ofuna ukuba ulwelo olulinganisiweyo lube nenqanaba elithile lokuqhuba umbane. Ngokwesiqhelo, ukuqhuba kolwelo kufuneka kube ngaphezulu kune5 μS/cm(ii-microsiemens ngesentimitha); kungenjalo, i-voltage ebangelwayo iya kuba buthathaka kakhulu ukuba ingalinganiswa ngokuchanekileyo.
Iimeko ezingafanelekanga:
- Amanzi acocekileyo, amanzi angena ion
- Iimveliso zepetroliyam (umz., ipetroliyam, idizili)
- Izinyibilikisi zendalo ezikhusela kakhulu (umz., i-ether, i-benzene)
2. Ayifanelekanga kwiGesi, kwi-Steam, okanye kwi-Solids eyomileyo ngokupheleleyo
Ekubeni iimitha zokuhamba kwe-electromagnetic zifuna ukuba umbhobho uzaliswe ngokupheleleyo lulwelo ukuze kulinganiswe ngokuzinzileyo, azinakusetyenziselwa ukulinganisa ukuhamba kwegesi, umphunga, okanye umlinganiselo wokuhamba okuqinileyo okomileyo ngokupheleleyo.
Iimeko ezingafanelekanga:
- Umlinganiselo womoya ocinezelweyo, ukuhamba kwegesi yendalo
- Ukulinganiswa kokuhamba komphunga
- Iipowuda ezomileyo okanye izinto ezibunjiweyo (umz., isamente, iinkozo)
3. Ulwelo oludlaka okanye olunobushushu obuphezulu lunokuchaphazela ubomi beSensor
Nangona iimitha zokuhamba kwe-electromagnetic zinokuxhotyiswa ngee-linings ezimelana nokugqwala (ezifana ne-PTFE) kunye nee-electrodes (umz., i-Hastelloy, i-Tantalum), ezinye iindawo ezinobungozi zisenokuchaphazela ukuzinza kunye nobude bexesha lezixhobo. Ii-asidi ezinamandla, iziseko ezinamandla, okanye ulwelo olushushu kakhulu lunokukhawulezisa ukuguga okanye umonakalo we-sensor.
Iimeko ezingafanelekanga:
- I-asidi yesulfuric enoxinzelelo oluphezulu, i-asidi ye-hydrofluoric, kunye nezinye izinto ezibangela ukubola okukhulu
- Ulwelo olunamaqondo obushushu adlula ukunyamezela kwezinto (umz., >180°C)
4. Amanqanaba okuhamba kwamanzi aphantsi okanye ulwelo oluneebhamuza lunokuchaphazela uzinzo
Iimitha zokuhamba kwe-electromagnetic ziyasokola ukulinganisa amazinga okuhamba aphantsi (ngesiqhelo zingaphantsi0.1 m/s) ngokuchanekileyo kuba i-voltage ebangelwayo ibuthathaka kwaye isengozini yokuphazamiseka. Ngaphezu koko, ukuba ulwelo lunezixa ezibalulekileyo zamaqamza omoya, isignali ingazinzi, ichaphazele ukuchaneka komlinganiselo.
Iimeko ezingafanelekanga:
- Ukulinganiswa kolwelo oluhamba kancinci kakhulu (umz., ukuvuza, ukulinganisa iikhemikhali ezihamba kancinci)
- Ulwelo olunegesi eninzi (umz., izisombululo zeekhemikhali ezisandula ukuxutywa, amanzi amdaka afakwe umoya)
5. Iindawo ezineNgxaki enamandla ye-Electromagnetic
Iimitha zokuhamba kwe-electromagnetic zinovelwano kukuphazamiseka kwe-electromagnetic yangaphandle. Ukuba indawo yokufakela ikufutshane neemoto ezinkulu, ii-variable frequency drives, okanye imigca yamandla ene-voltage ephezulu, oku kunokuphazamisa ukuzinza kwemilinganiselo.
Iimeko ezingafanelekanga:
- Kufuphi nezikhululo zamandla okanye iintambo zamandla ezinamandla aphezulu
- Iindawo ezinamandla zemagnethi (umz., iimoto ezinkulu, izixhobo zokuwelda)
Isiphelo: Ungayikhetha njani iMitha yoMsinga oLungileyo?
Ukuba isicelo sakho siyahlangabezana nale miqathango ilandelayo, imitha yokuhamba kwe-electromagnetic ingaba lukhetho oluhle kakhulu:
✅ Ulwelo lulwelo kwaye lunomoya owaneleyo wokuhambisa umbane
✅ Ubushushu kunye nokubola kolwelo kuwela ngaphakathi koluhlu lokunyamezelana kwemitha
✅ Umbhobho uzaliswe ngokupheleleyo lulwelo, kwaye izinga lokuhamba kwamanzi alikho phantsi kakhulu
✅ Indawo yokufakela ayinazo iziphazamiso ezinkulu ze-electromagnetic
