I. Core Product Positioning
Graphite Sealing Cylinder Gasket yog ib qho tseem ceeb ntawm cov khoom siv sib khi ntawm cov tshuab hluav taws xob sab hauv, siv siab -purity graphite ua cov khoom tseem ceeb sealing. Nws yog tsim los rau cov kev ua haujlwm nyuaj ntawm cov cav nyob rau hauv qhov kub thiab txias. Leveraging zoo heev sealing thiab kub tsis kam ntawm graphite, nws ua tiav kev sib cais ntawm combustion chamber gases, cav roj, thiab coolant, tshem tawm tshuab-los ntawm cov teeb meem. Qhov no muab kev txhawb nqa tseem ceeb rau cov khoom siv hluav taws xob ruaj khov, kev ua haujlwm zoo, thiab lub neej ntev ntawm lub cav, thiab tsim nyog rau ntau hom cav xws li roj -powered thiab hybrid xyaw.

III. Cov yam ntxwv tseem ceeb
1.Excellent Sealing thiab Temperature Resistance
High- ntom graphite nrog purity ntawm Ntau dua lossis sib npaug li 99.5% yog siv los ua txheej txheej sealing, ua ke nrog qis- carbon steel / 304 stainless hlau txhawb txheej. Cov txheej graphite tuaj yeem ua kom haum rau qhov sib txawv me me ntawm qhov chaw sib khi, tswj kev sib khi kev ncaj ncees nyob rau hauv qhov kub thiab txias ntawm 1800℃thiab siab kawg siab ntawm 25MPa. Lub tshuab-los ntawm tus nqi raug txo los ntawm ntau dua 65% piv rau cov khoom siv zoo tib yam lub tog raj kheej gaskets, thiab nws tuaj yeem tiv taus ntev ntev -lub sijhawm kub ntawm -40℃txog 400℃yam tsis muaj kev ua haujlwm degradation.
2. Muaj zog Corrosion Resistance thiab nruab nrab Resistance
Graphite nws tus kheej muaj zog tshuaj stability. Tom qab kev kho tshwj xeeb, nws tuaj yeem tiv taus ntev - lub sij hawm yaig los ntawm cov roj cav, ethylene glycol coolant, roj, thiab combustion pa roj, tsis muaj o los yog laus tom qab immersion. Nyob rau tib lub sijhawm, nws tiv taus ultraviolet rays thiab ozone, thiab nws cov sealing kev ua tau zoo degradation yog tsawg dua 3% nyob rau hauv kev ua haujlwm nyuaj.
3.High Adaptive Compensation Capability
Lub graphite sealing txheej muaj tus nqi compression ntawm 18% mus rau 22% thiab tus nqi rov zoo dua los yog sib npaug rau 88%. Nws tuaj yeem them rov qab rau me me deformations ntawm lub tog raj kheej thaiv / lub taub hau los ntawm kev hloov pauv kub, nrog rau qhov tsis sib xws hauv 0.12 hli ntawm qhov sib khi nto thaum lub sijhawm teeb tsa. Kev ruaj ntseg sealing tuaj yeem ua tiav yam tsis tas yuav tsum tau sealant ntxiv, txo cov kev sib dhos nyuaj.
4.High Precision thiab Durability
Siv CNC laser txiav thiab precision stamping txheej txheem, qhov ntev ntev yog tswj nyob rau hauv ± 0.015mm, kom ntseeg tau 100% match ntawm qhov chaw thiab lub cav. Cov txheej graphite thiab cov txheej txheem txhawb nqa yog sib xyaw ua ke los ntawm siab - kub molding, tshem tawm cov kev pheej hmoo ntawm delamination. Tom qab kev sim, lub cav tuav lub sealing siab tuav tus nqi ntawm ntau dua los yog sib npaug li 92% txawm tias tom qab 12,000 sib law liag pib thiab nres thiab 6,000 cov sij hawm ua hauj lwm, ncua lub neej kev pab cuam los ntawm 90% piv rau cov tsoos gaskets.
5.Kev tiv thaiv ib puag ncig thiab yooj yim ntawm kev teeb tsa
Cov khoom siv Graphite ua tau raws li RoHS thiab REACH ib puag ncig cov qauv, tsis muaj cov tshuaj phem tso tawm. Cov npoo ntawm lub sealing nto yog sib npaug los tiv thaiv khawb lub tog raj kheej thaum lub sijhawm teeb tsa, uas tuaj yeem txhim kho kev sib dhos ua haujlwm los ntawm 30% thiab txo qis kev ua haujlwm yuam kev.
IV.Scope ntawm daim ntawv thov
Daim ntawv thov Scenario
Muaj feem xyuam rau cov khoom siv uas muaj cov cav sib xyaw ua ke, xws li cov neeg caij tsheb (nruab nrab- mus rau- siab- kawg sedans, siab -kev ua tau zoo SUVs, tsheb kis las), tsheb ua lag luam (hnyav- cov tsheb thauj khoom, ntev- cov tsheb npav deb), tsheb thauj khoom txias, tsheb thauj khoom, tsheb thauj khoom, tsheb thauj khoom crawler cranes), marine power (dej hiav txwv- mus cargo ships, offshore patrol nkoj), generator sets (high-power diesel generators, gas generator sets), thiab tsheb tshwj xeeb ( tsheb thauj khoom thaum muaj xwm ceev, tub rog tawm - tsheb ciav hlau).
Tau tshaj Cav Hom
Nws yog sib xws nrog roj av thiab diesel xyaw uas txais yuav tej yam ntuj tso aspiration, turbocharging, supercharging, thiab lwm yam intake txoj kev, tshwj xeeb tshaj yog high -kawg cav nrog high compression piv (Ntau tshaj los yog sib npaug rau 13: 1) thiab siab zog ceev (Ntau tshaj los yog sib npaug rau 40kW / L). Nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm sealing raws li kev ua haujlwm hnyav.
