Mokhoa oa ho Khetha Seteishene se Nepahetseng sa Phallo ea Elektromagnetic

Ha o khethasesupa-tsela sa phallo ea motlakase(EMF), lintlha tse 'maloa tsa bohlokoa li lokela ho nahanoa ho netefatsa litekanyo tse nepahetseng le botšepehi ba nako e telele:

1. Litlhoko tse Mahareng
   Mokelikeli o lokela ho ba o tsamaisang motlakase (hangata ≥5 μS/cm), joalo ka:

• Metsi (metsi a pompo, likhoerekhoere, metsi a leoatle)
• Litharollo tsa asiti le alkaline (indasteri ea lik'hemik'hale)
• Lerotholi, lero la pulp, le lerotholi la diminerale (metswako e tiileng le e metsi e tsamaisang metsi)

Ha e lokele maro a sa tsamaiseng motlakase, joalo ka:

1. • Metsi a hloekisitsoeng, metsi a hloekisitsoeng
   • Oli (peterole, peterole, disele)
   • Litharollo tse itseng tsa tlhaho (mohlala, joala, benzene)
2. Bophara ba Phaephe le Sekhahla sa Phallo
   Khetha sesupa-tsela sa phallo se tsamaellanang le sebaka se loketseng sa phallo. Ka kakaretso, lebelo la phallo la 1–5 m/s lea khothaletsoa. ​​Lebelo la phallo le tlase haholo le ka ama ho nepahala ha tekanyo, athe hodimo haholo ho ka eketsa tahlehelo ya kgatello.
   Bophara ba phaephe bo lokela ho lekana le boholo ba mithara ya phallo. Haeba lebelo la phallo le le tlase haholo, kgetha bophara bo bonyenyane ho ntlafatsa botsitso ba tekanyo.
3. Khetho ea Electrode le Thepa ea Lera
   Thepa ea li-electrode le lesela la ho roala e lokela ho khethoa ho latela ho bola, mocheso le maemo a ho tsofala ha mokelikeli:

   Thepa	Medium e Loketseng
   Lisebelisoa tsa li-electrode
   Tšepe e sa Hlakeng ea 316L	Likhoerekhoere, maro a sa nke lehlakore
   Tantalum (Ta)	Li-acid tse matla (mohlala, nitric acid, sulfuric acid)
   Platinum (Pt)	Metsi a senyang haholo, a mocheso o phahameng
   Titanium (Ti)	Metsi a leoatle, metsi a nang le chloride
   Lisebelisoa tsa ho roala lesela
   Rabara	Metsi a akaretsang, likhoerekhoere, lerōle
   PTFE (Teflon)	Li-acid tse matla, li-alkali tse matla
   Neoprene	Metsi a nang le dikarolwana, diminerale tse qhibilihisitsoeng

4. Maemo a ho kenya
   • Bolelele ba Phaephe e Otlolohileng: Bolelele bo kgothaletswang pele ho metara ya phallo ke ≥makgetlo a 5 a bophara ba phaephe le ≥makgetlo a 2 kamora mithara ho qoba maemo a phallo a sitisitsweng.
   • Phallo e Felletseng ea Phaephe: Seteishene sa phallo se lokela ho kenngoa karolong ea phaephe e tletseng ka botlalo ho thibela lipululana tsa moea le liphaephe tse se nang letho ho ama ho nepahala ha tekanyo.
   • Mabaka a Tikoloho: Qoba tšitiso e matla ea motlakase ho tsoa mehloling e kang li-drive tsa maqhubu a feto-fetohang kapa li-motor; ho tsitsa hantle hoa hlokahala.
5. Protokhole ea Letšoao la Tlhahiso le Puisano
   • Matšoao a Analog: 4-20mA (letšoao le tloaelehileng la indasteri)
   • Puisano ea Dijithale: RS485 (Modbus), HART, Profibus
   • Tlhahiso ea Pulse: E loketse lits'ebetso tsa ho lekanya
6. Phepelo ea motlakase
   • AC 220V/110V (bakeng sa lits'ebetso tse tsitsitseng)
   • DC 24V (bakeng sa litsamaiso tsa othomathike tsa indasteri)
   • E tsamaisoa ke betri (bakeng sa libaka tse hole ntle le matla a kantle)
7. Litlhoko tse ling tse ikhethang
   • Tekanyo ea Litsela Tse PediHaeba ho hlokahala tekanyo ea phallo e khutlelang morao, khetha mohlala o tšehetsang tekanyo ea mahlakoreng a mabeli.
   • Tekanyetso ea Tšireletso: IP65 (tikoloho tse akaretsang), IP67/IP68 (tikoloho tse kantle kapa tse ka tlas'a metsi).
   • Litlhoko tse sa Phalleng: Bakeng sa tšebeliso libakeng tsa petrochemical kapa tse kotsi, ho lokela ho khethoa sesupa-tsela sa phallo se sa phatloheng.

Ho nahana ka lintlha tsena ho tla u thusa ho khetha sesupa-tsela se nepahetseng sa phallo ea motlakase bakeng sa ts'ebeliso ea hau.
