Ungayikhetha njani iMitha yokuHamba kwe-Electromagnetic efanelekileyo?

Xa ukhethaimitha yokuhamba kwe-electromagnetic(EMF), kufuneka kuqwalaselwe izinto ezininzi ezibalulekileyo ukuqinisekisa ukulinganiswa okuchanekileyo kunye nokuthembeka kwexesha elide:

1. Iimfuno eziphakathi
   Ulwelo kufuneka luqhube umbane (ngesiqhelo ≥5 μS/cm), olufana nolu:

• Amanzi (amanzi epompo, amanzi amdaka, amanzi olwandle)
• Izisombululo ze-asidi kunye ne-alkaline (ishishini leekhemikhali)
• Udaka, intlama, kunye nodaka lweeminerali (imixube eqinileyo-yolwelo ehambisa umbane)

Ayifanelekanga kwiincindi ezingasebenzisi umbane, ezifana nezi:

1. • Amanzi acocekileyo, amanzi acociweyo
   • Iioyile (ipetroli, ipetroli, idizili)
   • Izinyibilikisi ezithile zendalo (umz., utywala, ibenzene)
2. Ububanzi bePipe kunye neNqanaba lokuhamba
   Khetha imitha yokuhamba ehambelana noluhlu olufanelekileyo lokuhamba. Ngokubanzi, isantya sokuhamba se-1–5 m/s siyacetyiswa. Isantya sokuhamba esiphantsi kakhulu sinokuchaphazela ukuchaneka kokulinganisa, ngelixa ukuphakama kakhulu kunokunyusa ukulahleka koxinzelelo.
   Ububanzi bombhobho bufanele bulingane nobukhulu bemitha yokuhamba kwamanzi. Ukuba isantya sokuhamba kwamanzi siphantsi kakhulu, khetha ububanzi obuncinci ukuphucula uzinzo lokulinganisa.
3. Ukukhethwa kwe-Electrode kunye nezinto zokufaka ilini
   Izinto ezisetyenziswa kwii-electrodes kunye ne-lining kufuneka zikhethwe ngokusekelwe ekubeni ulwelo lunokubola kangakanani, ubushushu, kunye neemeko zokuguguleka kwalo:

   Izinto eziphathekayo	Iphakathi efanelekileyo
   Izixhobo ze-Electrode
   Intsimbi Engagqwaliyo engama-316L	Amanzi amdaka, ulwelo olungathathi cala
   I-Tantalum (Ta)	Iiasidi ezinamandla (umz., i-asidi ye-nitric, i-asidi ye-sulfuric)
   Iplatinum (Pt)	Ulwelo olune-corrosive kakhulu, olushushu kakhulu
   I-Titanium (iTi)	Amanzi olwandle, ulwelo olunekloridi
   Izinto zokugquma
   Irabha	Amanzi ngokubanzi, amanzi amdaka, udaka
   I-PTFE (iTeflon)	Iiasidi ezinamandla, iialkali ezinamandla
   I-Neoprene	Ulwelo oluneziqwenga, iiminerali ezilulwelo

4. Iimeko zoFakelo
   • Ubude bePipe Ethe Tye: Ubude obucetyiswayo ngaphambi kwemitha yokuhamba buphindwe ka-≥5 ubukhulu bepayipi kwaye buphindwe ka-≥2 emva kwemitha ukuphepha ukuphazamiseka kweemeko zokuhamba.
   • Ukuhamba kweMibhobho Epheleleyo: Imitha yokuhamba kufuneka ifakwe kwicandelo lemibhobho elizaliswe ngokupheleleyo ukuthintela amaqamza omoya kunye nemibhobho engenanto ukuba ingachaphazeli ukuchaneka kokulinganisa.
   • Izinto Ezichaphazela Ukusingqongileyo: Kuphephe ukuphazamiseka okukhulu kwe-electromagnetic okuvela kwimithombo efana nee-variable frequency drives okanye ii-motors; kubalulekile ukuba umhlaba uqine ngokufanelekileyo.
5. Iprotokholi yeSignali yeziphumo kunye noNxibelelwano
   • Iimpawu ze-Analog: 4-20mA (isignali eqhelekileyo yemizi-mveliso)
   • Unxibelelwano lweDijithali: RS485 (Modbus), HART, Profibus
   • Isiphumo sePulse: Ifanelekile kwizicelo zokulinganisa
6. Ukunikezwa Amandla
   • I-AC 220V/110V (yofakelo olusisigxina)
   • I-DC 24V (yeenkqubo ze-automation zoshishino)
   • Isebenza ngebhetri (kwiindawo ezikude ezingenamandla angaphandle)
7. Ezinye iimfuneko ezikhethekileyo
   • Ukulinganisa iiNdlela ezimbiniUkuba kufuneka umlinganiselo wokuhamba okungasemva, khetha imodeli exhasa umlinganiselo wecala ngalinye.
   • Uvavanyo loKhuseleko: IP65 (iindawo ezingqongileyo ngokubanzi), IP67/IP68 (iindawo ezingaphandle okanye ezingaphantsi kwamanzi).
   • Iimfuneko ezichasene nokuqhuma: Ukuze isetyenziswe kwiindawo ze-petrochemical okanye ezinobungozi, kufuneka kukhethwe imitha yokuhamba kwamanzi engaqhumiyo.

Ukuqwalasela ezi zinto kuya kukunceda ukhethe imitha yokuhamba kwe-electromagnetic efanelekileyo kwisicelo sakho.
