Oil & Gas Exploration Seals Description
Roj thiab roj kev tshawb nrhiav cov ntsaws ruaj ruaj yog qhov tseem ceeb ntawm cov roj thiab roj kev tshawb nrhiav thiab cov txheej txheem tsim khoom, thiab lawv lub luag haujlwm tseem ceeb yog tiv thaiv cov roj thiab cov pa tawm, ua kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm kev ua haujlwm. Nov yog cov lus qhia luv luv rau cov roj thiab roj tshawb nrhiav cov ntsaws ruaj ruaj:
Qhov tseem ceeb ntawm kev tshawb nrhiav roj thiab roj foob
Cov roj thiab cov roj tshawb nrhiav cov ntsaws ruaj ruaj ua lub luag haujlwm tseem ceeb hauv kev tshem tawm roj thiab roj. Lawv tau siv los kaw cov kev sib txuas ntawm ntau yam khoom siv thiab cov kav dej kom tsis txhob muaj cov roj, cov pa roj thiab cov pa phem, txo cov pa phem ib puag ncig, thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Vim yog qhov nyuaj ntawm qhov chaw tshawb nrhiav roj thiab roj, cov ntsaws ruaj ruaj yuav tsum muaj peev xwm tiv taus cov xwm txheej hnyav xws li kev kub ntxhov, kub kub, thiab tshuaj lom neeg corrosion.
Kev faib tawm ntawm cov ntsaws ruaj ruaj
Cov roj thiab roj tshawb xyuas cov ntsaws ruaj ruaj tuaj yeem muab faib ua cov pawg hauv qab no raws li lawv cov kev siv thiab cov yam ntxwv ntawm cov qauv:
Cov ntsaws ruaj ruaj: feem ntau yog siv rau kev sib khi ruaj khov txuas, xws li flange kev twb kev txuas, threaded kev twb kev txuas, thiab lwm yam. Cov ntsaws ruaj ruaj uas muaj xws li O-rings, U-rings, Y-rings, thiab lwm yam.
Dynamic seals: feem ntau yog siv rau sealing rotating los yog reciprocating qhov chaw, xws li bearings, piston rods, thiab lwm yam. Common txav ntsaws ruaj ruaj muaj xws li mechanical seals, di ncauj seals, thiab lwm yam.
Combination seals: Complex sealing systems muaj ntau yam sealing ntsiab kom tau raws li qhov tshwj xeeb sealing.
Kev siv cov seals
Cov roj thiab roj tshawb xyuas cov ntsaws ruaj ruaj yog siv dav hauv ntau qhov chaw ntawm cov khoom siv tshawb nrhiav roj, xws li cov khoom siv drilling, cov av nkos, cov khoom siv hauv lub taub hau, thiab lwm yam. Lawv tuaj yeem tsis tsuas yog tiv thaiv ib puag ncig cov pa phem thiab pov tseg ntawm cov khoom siv los ntawm cov roj thiab cov pa xau, tab sis kuj txo qis. cov khoom siv tsis ua haujlwm thiab cov nqi tu, thiab txhim kho kev ua haujlwm zoo thiab kev nyab xeeb.
| Roj kuj | Kub tiv taus | Corrosion kuj | Kev laus tsis kam |
| Cov khoom siv foob yuav tsum muaj cov roj zoo los tiv thaiv cov tshuaj lom neeg muaj pes tsawg leeg hauv cov roj thiab qhov kub thiab txias ib puag ncig, thiab tswj nws cov khoom qub los ntawm kev yaig. | Cov roj thiab roj tshawb xyuas cov ntsaws ruaj ruaj yuav tsum muaj kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias lossis txawm tias ultra-siab kub ua haujlwm ib puag ncig. Yog li ntawd, cov khoom siv sealing yuav tsum muaj qhov kub thiab txias tsis kam, thiab tib lub sijhawm, nws yuav tsum muaj qhov kub thiab txias tsis zoo nyob rau qee qhov chaw kub. | Txij li cov kua dej zoo hauv lub qhov dej feem ntau muaj ntau yam tshuaj, xws li acids, alkalis, ntsev, thiab lwm yam, cov ntaub ntawv foob yuav tsum muaj kev tiv thaiv zoo heev los tiv thaiv kev yaig ntawm cov xov xwm corrosive. | Sealing cov ntaub ntawv yuav raug cuam tshuam los ntawm oxidation, tshav kub laus, ultraviolet rays thiab lwm yam tseem ceeb thaum lub sij hawm siv mus sij hawm ntev, ua rau degraded kev ua tau zoo. Yog li ntawd, cov khoom siv sealing yuav tsum muaj kev laus zoo los tiv thaiv cov teebmeem ntawm cov teebmeem no |
Cov kev xav tau ntawm kev ua haujlwm rau cov ntsaws ruaj ruaj
Hauv kev tshawb nrhiav roj av, cov ntsaws ruaj ruaj yuav tsum tau ua kom tau raws li cov kev xav tau nruj me ntsis hauv qab no:
Cov roj ua haujlwm zoo, qhov kub thiab txias tsis kam tiv thaiv corrosion los tiv thaiv kev ua haujlwm hnyav.
High sealing kev ua tau zoo thiab lub neej ua haujlwm ntev kom ntseeg tau tias lub sijhawm ua haujlwm ruaj khov ntawm cov khoom siv.
Zoo hnav tsis kam, kev laus ua haujlwm thiab nws tus kheej lubrication los txo kev sib txhuam thiab hnav thiab txhim kho kev ua haujlwm ntawm cov khoom siv.

Kev xaiv khoom
Kev xaiv cov khoom siv rau lub foob yog qhov tseem ceeb rau nws qhov kev ua tau zoo. Cov khoom siv feem ntau suav nrog roj hmab, fluoroelastomer, polytetrafluoroethylene (PTFE), thiab ntau yam khoom siv hluavtaws. Roj hmab muaj qhov zoo elasticity thiab sealing, haum rau kev ua haujlwm dav dav. Fluoroelastomers thiab PTFE yog tsim rau hnyav ib puag ncig vim lawv cov tshuaj tsis haum thiab kub tsis kam.
