Kev sealing kev ua tau zoo thiab thiav ntawm pob li qub thiab lwm yam valve hnyav hnyav nyob ntawm kev sib cuag nto ntawm tusPob thiab rooj zaumCov. Ua kom zoo duaNto Kho, cov khoom xaiv, thiab nto tiavtuaj yeem txhim khoSealing efficiency, hnav tsis kam, thiab ua haujlwm ua haujlwmhauv kev thov cov ntawv thov.
1. Hu rau cov kev kho saum npoo av
- Lapping & Polishing: High-precisionlapping thiab daim iav polishingtxo cov npoo av (feem ntau rauRa tsawg dua lossis sib npaug rau 0. 1 μm), ua kom pom kev nruj me ntsis thiab muab kev hnav khaub ncaws.
- Tawv xim tawv:
- Chromium carbide (CR3C2) lossis tungsten carbide (WC) Txheejthov ntawmHVOF (High-Velocity Pa Roj) Txautxhim kho hardness (mus txog1200 HV) thiab ua phem tsis kam.
- Pob zeb diamond zoo li Carbon (DLC) Txheejtxo kev sib txhuam coefficients (<0.1) Hauv cov ntawv thov siab.
- Laser nto Texturing: Micro-grooves lossis dimples tsim los ntawmLaser Texturingua kom zoo duaDej roj nplua nyeem Ceev, Txo kev hnav hauv qhuav lossis qis-lubrication cov xwm txheej.
2. Cov khoom xaiv rau pob & rooj zaum
- Hlau-rau-Hlau Ntsaws Ruaj Ruaj:
Stainless hlau (316L, 17-4 pH)rau kev tiv thaiv corrosion.
Hastelloy C276 lossis Inconel 625rau kev tshuaj lom huab \/ acidic ib puag ncig.
Stellite 6 (co-c alloy)rau kev kub kub thiab abrasive xov xwm.
- Mos rooj (Elastomeric \/ Polymer):
PTFE (Teflon): Cov tshuaj zoo heev tiv thaiv tab sis txwv rau<200°C.
Peek (Poleether ether Ketone): Ntau kub tiv thaiv (Txog li 260 degree) Nrog hnav zoo hnav.
Ultra-siab molecular hnyav polyethylene (UHMWPE): Superior ua paug tawm tsam rau cov ntawv thov slurry.
3. Nto tiav kev ua kom zoo
Qhov zoo tagnrho roughness values:
- Hlau Rooj: Ra {{{0}}. 2-0.4 μmrau kev sib npaug ntawm kev sib khi thiab hnav.
- Mos Rooj: Ra 0. 8-1.6 μmTxhawm rau tso cai me ntsis embedment rau kev sib khi zoo dua.
- Ceev superfinishing: Electrochemical Polishing (ECP)lossisSib Nqus Abrasive Xov (Maf)tuaj yeem ua tiavRa <{0. 05 μm, txo cov kev pheej hmoo txaus ntshai.
4. Tsim kev txhim kho rau cov sealing & hnav txo
Hu Xov Tooj Sib Tw:
- Cov Khoom Siv Hluav Taws Xob lossis Khoom Siv TogXyuas kom ntseeg tau tias muaj kev faib tawm siab, tsis txhob hnav hauv zos hnav.
- Lub caij nplooj ntoos hlav-energized rooj zaumTswj kev sib cuag sib tiv thaiv txawm tias muaj kev nthuav dav kub \/ cog lus.
Nws tus kheej lubricating tsim:
- Graphite-impregnated rooj zaumTxo cov kev sib txhuam hauv qhov ntsuas kub-ntsuas.
- Mos2 (Molybdenum Disulfide) TxheejRau cov kev ua haujlwm tsawg hauv nqus tsev \/ roj tshuab.
5. Cov kev sib tw & kev daws teeb meem
- Hnav nyob rau hauv abrasive xov xwm: SivWC-CO Txheej TxheejlossisCeramic (Sic \/ AL2O3)Rau cov kev pabcuam slurry.
- Thermal Cycling Nrov: Thermal kev ntxhov siab-relieved tsim qauvthiabCov Khoom Uas Cov Khoom Siv Khoom Hloovtiv thaiv kev qaug zog tsis ua haujlwm.
- Lock-Sawb Prenomenon: Laser-textured ntolossisPTFE-bedit RojricantsTshuaj ntsuab Galling.
6. Yav Tom Ntej Tiam
- Ntse Engineering: Embedded Microscedrau kev saib xyuas lub sijhawm thaum lub sijhawm thaum lub sijhawm tiag tiag.
- Nanocomposite tsho nplaum: Graphene-txhawb koob yeesRau cov ultra-tsawg kev sib txhuam thiab corrosion tsis kam.
- Ntxiv Kev Lag Luam: 3D-printed lattice-txheej txheem chawRau kev ua kom zoo tshaj plaws.
Txhim kho covPob-Rau-Tog Sib ThamdhauAdvanced Txheej, Precision Tiav, thiab Cov Khoom Siv Innovationyog qhov tseem ceeb rau kev ua tiavxoom-to zwgage kev ua tau zoo thiab txuas ntxiv lub neejCov. Cov thev naus laus zis zoo liLaser Texturing, Cov Ntaub Ntawv Ntse, thiab Additive Raugyog teem rau redefine valve kev daws teeb meem hauvRoj & Roj, Tshuaj Lom Zem, thiab Lub Zog Hluav Taws Xob.
