Boikoetliso ba 4-1: Taolo e sa Tobang Ho Sebelisa Li-Valves tse Tsamaisang Pilot

2024-07-29

Ho Utloisisa Li-Valves tse Tsamaisang Pilot

Li-valve tse tsamaisoang ke Pilot (POVs) ke mofuta oa li-valve tsa taolo tse sebelisang valve e nyane, e thusang (mofofane) ho laola phallo ea mokelikeli ka valve e kholoanyane. Valve ea sefofane, e sebelisoang ke lets'oao la khatello kapa keno e 'ngoe, e laola boemo ba spool kapa piston ea valve e kholo. Mokhoa ona oa ho laola ka tsela e sa tobang o fana ka melemo e 'maloa, ho kenyelletsa le taolo e nepahetseng, kutloisiso e eketsehileng, le bokhoni ba ho sebetsana le litekanyetso tse phahameng tsa phallo.

Kamoo Li-valve tse Tsamaisang Lifofane li Sebetsang Kateng

1.Pilot Valve Activation:Letšoao la khatello, lets'oao la motlakase, kapa ho kenya mochini ho kenya tšebetsong valve ea sefofane.

 

2.Pilot Valve Taolo ea Koloi ea Bohlokoa:Motsamao oa valve ea sefofane o tsamaisa phallo ea mokelikeli ho diaphragm kapa piston ka har'a valve e kholo.

 

3.Main Valve Boemo:Phapang ea khatello e entsoeng ke valve ea sefofane e etsa hore valve e kholo e bulehe kapa e koalehe, e laolang ho phalla ha metsi a mangata.

 

Melemo ea Li-valve tse tsamaisoang ke Pilot

• Taolo e Nepahetseng:Li-valve tse tsamaisoang ke lifofane li fana ka taolo e hlophisitsoeng hantle holim'a phallo ea mokelikeli, e leng se etsang hore e be tse loketseng lits'ebetso tse hlokang taolo e nepahetseng.

 

• Litefiso tse Phahameng tsa Phallo:Li-valve tsena li ka sebetsana le litekanyetso tse phahameng tsa phallo ha li ntse li boloka taolo e nepahetseng.

 

• Ts'ebetso ea Remoutu:Li-valve tse tsamaisoang ke lifofane li ka laoloa ka thōko ho sebelisa matšoao a fapaneng a ho kenya, ho nolofalletsa ho iketsetsa le ho kopanngoa le mekhoa e meholo ea taolo.

 

• Kutloisiso e Eketsehileng:Li-valve tse tsamaisoang ke lifofane li na le maikutlo a matla haholo ho liphetoho tsa matšoao a ho kenya, ho lumella nako ea karabo e potlakileng.

 

• 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.

Boikoetliso ba 4-1: Taolo e sa Tobang Ho Sebelisa Li-Valves tse Tsamaisang Pilot

Lisebelisoa tsa Li-valve tse tsamaisoang ke Pilot

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

 

Mesebetsi ea Boikoetliso le Menahano

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.

Lipotso tse ka 'nang tsa E-ba Teng ea Boikoetliso

• 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.
