Qhov Kawg Qhia Rau Cov Roj Hmab Sau Xaiv Ntaus: 3 Kauj Ruam rau Cov Chav Kawm Ua Kom Zoo thiab Cov Lus Qhia Tshwj Xeeb
Hauv kev tsom xam ntawm qhov cuam tshuam ntawm kev ntaus nqi ntawm kev ua yeeb yam ntawm cov tshuab roj hmab! Los ntawm ISO cov qauv los hla kev tsim qauv, peb yuav qhia koj kom koj xaiv cov rooj ua haujlwm zoo tshaj plaws raws li kev xaiv cov rooj rau kev xaiv kev ua haujlwm pub dawb.
Vim li cas thiaj muaj siab kawm qib siab lub neej-thiab-txoj kev tuag kab ntawm cov foob xaiv?
Hauv cov tshuab hydraulic, roj pipelines, thiab cov khoom siv muaj, ntau dua 68% ntawm cov cim ua tsis tiav yog vim muaj kev tsis sib haum xeeb (cov ntaub ntawv los txhim kho txoj cai). Cov roj hmab ntsaws ruaj ruaj yuav tsum tiv thaiv kev sib txawv ntawm cov kev mob tsis zoo rau 300Mpa ultra-siab muaj peev xwm ua rau xau dej, deformation, thiab txawm tias system tuag tes tuag taw. Kab lus no ua ke ntawm ASTM D1414 tus qauv nrog 30 xyoo ntawm kev paub txog kev lag luam kom tawg cov tub ntxhais lub siab xaiv rau koj.
Cov ntsiab lus txhais thiab kuaj cov qauv rau cov chav siab siab
Lub siab zoo nkauj vs impulse siab
Nruam siab lub tshuab (piv txwv li cov roj pipelines) tau raug rau Iso 3601-3 Txheem
Dynamic tetternios, xws li hydraulic kheej kheej, yog qhov yuav tsum yog 6072 Cyclic Testing
Burst Siab thiab Ua Haujlwm Siab Ruaj Ntseg
Kev lag luam kev lag luam yuav tsum tau foob tawg tawg ntau dua lossis sib npaug ntawm cov qauv ua haujlwm: P {} tawg × p ×}}} khiav haujlwm)
3 Cov Ntsiab Lus Xaiv Cov Ntsiab Lus Kev Sib Tw Sib Tw Rooj
Lub caij 1: Hom cim txiav txim siab qhov kev txwv siab
| Teal Hom | Siv tau siab ntau yam | Raug Daim Ntawv Teev Lus |
| O-rings (static foob) |
0 rau 40mpa |
Flange Kev Txuas, Kawg Cap Sealing |
| Kev Ua Hauj Lwm Gasket (Dynamic Foob) |
10 txog 100mpa |
Hydraulic Pistons, Pob Zeb Sib Tw |
| Yias Plug foob (ultra-siab siab) |
70 rau 300mpa |
Cov khoom sib sib zog nqus ntawm hiav txwv, cov kua dej supercritical |
Lub Caij 2: Cov Piv Txwv kub ntawm cov khoom hardness rau siab siab
Nitrile Butadiene Roj Hmab (NBR 70 Ntug Dej Ib): Tus nqi zoo tshaj plaws, haum rau <20mpa qes-siab scenarios
FluorooelAlomer (FKM 90 Ntug Dej 90: Kev Ua Siab Tawm, Tshuaj Corrosion Resistant, Zoo Tshaj rau {1}} mpa
Polyurethane (PU 95 Shore a): Ultra-High Modulus ntawm Elasticity, 200MPA Xav Tau
Lub caij 3: cov neeg kho tshuab code ntawm tus qauv hla
Siab-activated tsim: v-puab di ncauj tightens nws tus kheej nyob rau hauv siab
Kev Lom Zem Groove Technology: Trapezoidal Hla-tshooj disperses ntxhov siab cov ntsiab lus
Xaiv thiab Paim Davance Qhia: 3 3 feem ntau cov enclasers uas tsis tshua muaj neeg ua (hais txog cov neeg siv kev txhawj xeeb)
Tsis to taub: ncaj qha xaiv raws li lub siab ntawm cov raj xa dej
Kev daws teeb meem zoo: Peak siab yuav tsum tau muab suav (cov phuam sov rauj tawm tuaj yeem tsim 2.3 zaug ntawm cov siab Instantaneous)
HYTH: Tsis quav ntsej txog cov nyhuv superimposposposposposed ntawm kub ntawm siab
Piv Txwv: 40% txo qhov siab muaj peev xwm ntawm NBR ntsaws ntawm 100 degree (Astm D2000 Cov Ntaub Ntawv Hais)
HYTH: Kev loj hlob siv ib qho "txo qis kev xaiv"
Warning: Replacing the plug seal with an O-ring will result in a leak rate of >{{0 {0}}. 5% ib teev (ntsuas cov ntaub ntawv)
