Cov txiaj ntsig ntawm graphite packing rau cov twj paj nruag valve

Hauv kev siv hauv kev lag luam, kev xaiv cov khoom siv ntim khoom siv yog qhov tseem ceeb rau kev ua haujlwm zoo tshaj plaws thiab lub neej ua haujlwm. Ntawm ntau txoj kev xaiv muaj, cov khoom siv graphite sawv tawm rau lawv cov yam ntxwv tshwj xeeb thiab ntau yam txiaj ntsig. Tsab xov xwm no tshawb nrhiav cov txiaj ntsig ntawm cov khoom siv graphite tshwj xeeb rau cov khoom siv twj paj nruag, qhia txog vim li cas nws yog thawj qhov kev xaiv rau ntau lub lag luam.

Kev tiv thaiv kub zoo heev

Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm graphite filler yog nws qhov kub thiab txias zoo heev. Graphite tuaj yeem tiv taus qhov kub thiab txias heev, qee zaum, los ntawm qhov kub cryogenic mus rau ntau dua 500 ° C (932 ° F). Qhov no ua rau nws zoo tagnrho rau cov twj siv twj siv ua haujlwm hauv qhov chaw kub siab xws li roj thiab roj, kev ua tshuaj lom neeg thiab kev tsim hluav taws xob. Lub peev xwm los tswj kev ncaj ncees hauv qab cov xwm txheej zoo li no ua kom ntseeg tau tias lub valve ua haujlwm tau zoo yam tsis muaj kev pheej hmoo ntawm kev xau lossis ua tsis tiav.

Kev sib raug zoo ntawm cov tshuaj lom neeg zoo heev

Cov twj siv feem ntau siv ntau yam kua dej, suav nrog cov tshuaj lom neeg thiab cov khoom siv uas ua rau tawv. Cov khoom siv graphite fillers muaj kev tiv thaiv tshuaj lom neeg zoo, ua rau lawv siv tau rau hauv cov chaw uas cov khoom siv ib txwm muaj peev xwm lwj lossis ua tsis tiav. Nws qhov xwm txheej inert tso cai rau nws kom tiv taus kev raug cov kua qaub, cov hauv paus thiab cov kuab tshuaj, ua kom lub ntim khoom tseem zoo thiab ua haujlwm tau ntev. Qhov kev sib raug zoo ntawm cov tshuaj no tsis yog tsuas yog ua rau lub neej ntawm cov khoom ntim khoom ntev dua xwb, tab sis kuj txo cov nqi kho uas cuam tshuam nrog kev hloov pauv ntau zaus.

Kev sib txhuam tsawg thiab hnav tsis zoo

Lwm qhov zoo ntawm cov khoom siv graphite fillers yog lawv cov khoom sib txhuam tsawg. Thaum siv rau hauv cov twj paj nruag valves, graphite packing txo qhov hnav ntawm cov kav valve thiab lwm yam khoom, ua rau kev ua haujlwm du thiab txo kev siv zog. Qhov feature no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas lub valve voj voog ntau zaus lossis raug kev nyuaj siab. Qhov kev txo qis ntawm kev sib txhuam kuj pab txo qhov kub thiab txias, txhim kho qhov kev ua haujlwm zoo ntawm lub system.

Cov khoom siv lubricating tus kheej

Graphite yog ib yam roj nplua nyeem ntuj, uas txhais tau tias nws muab cov yam ntxwv uas nws tus kheej lubricating thaum siv los ua ib qho filler. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov twj paj nruag valves vim nws pab txo qhov xav tau ntxiv roj nplua nyeem, uas qee zaum tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub valve lossis ua rau cov xov xwm uas tau ua tiav. Cov yam ntxwv uas nws tus kheej lubricating ntawm graphite packing ua kom lub valve ua haujlwm zoo txawm tias nyob rau hauv cov xwm txheej hnyav.

Kev ua tau ntau yam thiab kev hloov kho kom haum

Cov khoom siv graphite fillers muaj ntau yam thiab tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm daim ntawv thov tshwj xeeb. Nws tuaj yeem tsim ntau yam duab, suav nrog braided, molded lossis extruded duab, muab cov kev daws teeb meem rau ntau hom twj paj nruag. Qhov kev hloov pauv no ua rau cov khoom siv graphite fillers haum rau kev siv hauv ntau yam lag luam, los ntawm cov tshuaj mus rau petrochemicals, kom ntseeg tau tias lawv tuaj yeem ua tau raws li qhov xav tau tshwj xeeb ntawm txhua daim ntawv thov.

Kev Siv Nyiaj Zoo

Txawm hais tias tus nqi pib ntawm cov khoom siv graphite fillers yuav siab dua li qee cov khoom siv ib txwm muaj, cov txiaj ntsig mus sij hawm ntev feem ntau ntau dua li kev nqis peev ua ntej. Cov khoom siv graphite filler lub zog ruaj khov, kev xav tau kev saib xyuas tsawg thiab lub neej ua haujlwm ntev pab txhawb rau kev txuag nyiaj ntau dhau sijhawm. Los ntawm kev txo qhov zaus hloov pauv thiab txo qhov tsis ua haujlwm, cov tuam txhab tuaj yeem ua tiav kev daws teeb meem zoo dua rau lawv cov twj paj nruag.

Ckev xaus

Hauv kev xaus lus, qhov zoo ntawm graphite packing rau cov twj paj nruag valve muaj ntau yam thiab txaus nyiam. Nws qhov kev tiv taus kub zoo, kev sib raug zoo ntawm cov tshuaj lom neeg, kev sib txhuam tsawg, cov khoom siv lubricating tus kheej, kev hloov pauv tau yooj yim thiab kev siv nyiaj tsim nyog ua rau nws zoo tagnrho rau ntau yam kev siv hauv kev lag luam. Raws li kev lag luam txuas ntxiv hloov zuj zus thiab xav tau cov kev daws teeb meem txhim khu kev qha thiab ua haujlwm tau zoo dua, graphite packing yuav tsis muaj qhov tsis ntseeg tias yuav yog thawj qhov kev xaiv los xyuas kom meej tias cov twj paj nruag valve ua haujlwm tau zoo tshaj plaws.
