• Likarolo tsa Tšireletseho:Li-valve tse ngata tse tsamaisoang ke lifofane li kenyelletsa likarolo tsa tšireletso tse kang mekhoa ea ho hlōleha ho thibela maemo a kotsi.
Li-valve tse tsamaisoang ke lifofane li fumana tšebeliso e ngata liindastering tse fapaneng, ho kenyelletsa:
• Litsamaiso tsa Hydraulic:
° Ho laola li-cylinders tsa hydraulic bakeng sa boemo bo nepahetseng
° Ho laola khatello ho li-circuits tsa hydraulic
° Ho kenya ts'ebetso e rarahaneng ea tatellano
• Sistimi ea Pneumatic:
° Ho laola li-actuator tsa pneumatic bakeng sa mesebetsi ea boiketsetso
° Ho laola khatello ea moea lipotolohong tsa moea
• Taolo ea Ts'ebetso:
° Ho laola sekhahla sa phallo lits'ebetsong tsa lik'hemik'hale
° Ho laola khatello ea liphaephe
° Ho boloka mocheso lits'ebetsong tsa indasteri
Ho phethela Boikoetliso ba 4-1 ka katleho, nahana ka mesebetsi le lintlha tse latelang:
• Hlalosa Likarolo:Itloaetse ka likarolo tse fapaneng tsa valve e tsamaisoang ke mofofisi, ho kenyelletsa le valve ea sefofane, valve e kholo le litselana tse hokahanyang.
• Utloisisa Molao-motheo oa Ts'ebetso:Utloisisa melao-motheo ea hore na phapang ea khatello le phallo ea mokelikeli li sebelisana joang ho laola valve e kholo.
• Sekaseka Mefuta e Fapaneng:Lekola mefuta e fapaneng ea li-valve tse tsamaisoang ke sefofane, joalo ka li-valve tse lefelloang ke khatello, tse laoloang ke phallo, le li-valve tse tsamaisoang ke motlakase.
• Nahana ka Likopo:Nahana ka lits'ebetso tse ikhethileng moo li-valve tse tsamaisoang ke lifofane li ka bang molemo le hore na li ka ntlafatsa ts'ebetso ea sistimi joang.
Rala Potoloho ea Taolo:Etsa potoloho e bonolo ea hydraulic kapa pneumatic e kenyelletsang valve e tsamaisoang ke sefofane ho laola mokhoa o itseng kapa mosebetsi.
• Belofo e tsamaisoang ke sefofane e fapana joang le e sebetsang ka kotloloho?
• Melemo ea ho sebelisa valve e tsamaisoang ke pilot tsamaisong ea haeteroliki ke efe?
• Etsa moralo oa potoloho ea valve e tsamaisoang ke sefofane ho laola lebelo la hydraulic cylinder.
• Hlalosa hore na valve ea liphallelo e tsamaisoang ke sefofane e sebetsa joang le karolo ea eona tsamaisong ea tšireletso.
• Buisanang ka lintlha tse susumetsang khetho ea valve e tsamaisoang ke sefofane bakeng sa ts'ebetso e itseng.
Ka ho phethela Boikoetliso ba 4-1, o tla fumana kutloisiso e tiileng ea melao-motheo, lits'ebetso, le melemo ea li-valve tse tsamaisoang ke lifofane. Tsebo ena e tla u fa matla a ho rala le ho kenya tšebetsong litsamaiso tse sebetsang tsa taolo maemong a fapaneng a indasteri.
Hlokomela:Ho fana ka karabo e lokiselitsoeng haholoanyane, ka kopo fana ka lintlha tse ling mabapi le litlhoko tse khethehileng tsa boikoetliso ba hau, joalo ka:
• Mofuta oa mokelikeli o laoloang (oli ea hydraulic, moea, joalo-joalo)
• Boemo bo lakatsehang ba taolo (ho tima/ho tima, tekano, jj.)
• Litšitiso leha e le life tse itseng kapa likhaello
Ka boitsebiso bona, nka fana ka tataiso le mehlala e lebisitsoeng ho feta.
