Commercial Vehicle Air Brake Valve body — GG25 Cast Iron Investment Casting

Kakaretso ea Sehlahisoa

The Commercial Vehicle Air Brake Valve Body ke karolo ea bohlokoa ea polokeho e laolang phallo ea moea e hatelitsoeng ho ea likamoreng tsa mariki ka literaka tse boima, libese le litereilara. Ho sebetsa likhatellong tsa sistimi ho fihla ho 10 bar (145 PSI) ka ho palama libaesekele ka potlako lipakeng tsa ho tlatsa le ho lokolloa, 'mele ona oa valve o hloka ho nepahala ho ikhethang, botšepehi bo tiileng, le ho tsitsa ha lintho. Ts'ebetso ea matsete a tšepe ea Ningbo Ruican's GG25 grey cast e fana ka geometry e rarahaneng ea ka hare ea boema-kepe, ho nepahala ha sehokelo, le ts'epahalo e nang le khatello e hlokoang ke baetsi ba sistimi ea brake ea likoloi. Sehlopha se seng le se seng sa li-valve se lekoa ka 100% 'me se netefalitsoe ka mokhoa o leka-lekaneng ho CMM ho netefatsa hore ho latela melao ea brake ea FMVSS 121 le ECE R13.

Litlhaloso tsa Lintho

Mokhoa oa Tlhahiso

1. Ente ea Wax Pattern : Ente e nepahetseng ea boka e nang le li-cores tsa boka tse qhibilihang bakeng sa litselana tsa moea tse ka hare
2. Mohaho oa khetla : khetla ea ceramic ea 7-9 e nang le seaparo sa mantlha sa zircon bakeng sa ho qeta holimo holimo
3. Dewaxing & Firing : Autoclave dewaxing ho 8 bar, shell e thunya ka 950 ° C.
4. Ho tšela : GG25 tšepe e bohlooho e tšeloa ka 1380-1420 ° C ka phekolo ea inoculation
5. Ho imolla khatellong ea maikutlo : Ho imolla ho 550°C bakeng sa lihora tse 2 ho imolla khatello ea maikutlo e setseng.
6. CNC Machining : Ho phethoha ha CNC le ho siloa ha likou tse khoele (G1/8, G1/4), lifahleho tse holimo, le boro ea piston.
7. Teko ea Khatello : Teko ea ho lutla ha moea ho 15 bar (1.5 × khatello ea ho sebetsa), ≤ 3 cc / min ho amoheloa
8. Phekolo ea Bokaholimo : Ho roala phosphate kapa ho roala ka elektroniki bakeng sa tšireletso ea kutu
9. Tlhahlobo : CMM dimensional, magnetic particle, hardness, leak test

Likarolo tsa Bohlokoa

• Complex Internal Porting : Ts'ebetso ea matsete e nang le li-cores tsa boka tse qhibilihang e etsa hore liteishene tsa moea tsa kahare li se khonehe ka ho lahla lehlabathe.
• Botšepehi ba Khatello ea Khatello : 100% e lekoa ho 15 bar (1.5 × khatello e lekantsoeng), e fetang litlhoko tsa FMVSS 121
• Li-ports tse Nepahetseng : Likhoele tsa G1/8 le G1/4 BSP tse kentsoeng ho mamella 6g bakeng sa lisebelisoa tse sa lutleng
• Piston Bore Precision : CNC-machine ho mamella H7 (± 0.01mm), e netefatsa hore piston e sebetsa hantle
• Ho Fokotsa Khatello ea Maikutlo : E kenyelelitsoe ho 550 ° C ho felisa khatello ea kelello e setseng, ho thibela ho senyeha ha tšebeletso.
• Tumellano ea Taolo : Ts'ebetso ea tlhahiso e tšehetsa PPAP bakeng sa setifikeiti sa FMVSS 121 le ECE R13

Libaka tsa Kopo

• Sistimi ea mariki a moea a literaka tse boima (li-valve tsa relay, li-valve tsa ho lokolla kapele)
• Sistimi ea mariki ea libese le mokoetlisi oa moea
• Li-valve tsa ho laola li-trailer le li-semi-trailer tse laolang mariki
• Li-valve tsa taolo ea ho emisa moea
• Mekhoa e mengata ea tsamaiso ea moea e hatelitsoeng

Hobaneng U Khetha Ningbo Ruican

Lilemo tse 17+ tsa Ningbo Ruican tsa ho etsa matsete ka tšepe e putsoa, ​​e kopantsoeng le setifikeiti sa IATF 16949, e re etsa mofani oa thepa ea ratoang bakeng sa baetsi ba likarolo tsa mariki a likoloi. 'Mele ea rona ea li-valve tsa GG25 e hlahisoa ka theknoloji ea boka ba boka ba metsi bakeng sa geometry e rarahaneng ea ka hare,' me karolo e 'ngoe le e' ngoe e etsa tlhahlobo ea ho lutla ha 100% khatellong ea ho sebetsa ea 1.5 ×. Re fana ka litokomane tse feletseng tsa PPAP Level 3, tšehetso ea ho lumellana le FMVSS / CEE, le lithuto tsa bokhoni (Cpk ≥ 1.33).
