Yuav Ua Li Cas Xaiv Cov Khoom Sealing rau Npauj Npaim Li Qub

Kev xaiv ntawm cov ntaub ntawv sealing rauNpauj Npaim Li QubYuav tsum muaj kev txiav txim siab ntawm ntau yam. Tsuas yog xaiv cov khoom zoo puas tuaj yeem tuav cov khoom zoo li cas kom muaj kev sib luag hauv ntau yam haujlwm ntawm cov kab ke. Hauv qab no yog cov yam ntxwv tseem ceeb thiab cov khoom muaj nqis los xav txog thaum xaiv:

Xav txog

1. Ua haujlwm nruab nrab cov khoom: Cov ntaub ntawv ntawm cov tshuaj lom neeg, xws li polytetrostoroethylene (PTFE), yuav tsum tau xaiv rau cov muaj zog acidic thiab alkaline ib puag ncig; Hais txog cov khoom siv lub cev, cov xov xwm kub siab tuaj yeem nrawm dua cov kev laus, thiab ib puag ncig muaj zog xav tau cov khoom siv siab thiab lub zog compressive. Media nrog cov siab particle impurities yuav tsum tau hnav-resistant cov ntaub ntawv.

2. Ua haujlwm kub thiab siab: Cov ntaub ntawv sib txawv: cov ntaub ntawv sib txawv muaj ntau yam kev siv ntsuas kub. Roj hmab sealing cov ntaub ntawv feem ntau siv ntawm -30 ℃ ℃ thiab 120 ℃, thaum tshwj xeeb engineering plastics tuaj yeem tiv thaiv ntau zaus. Nyob rau hauv cov kev mob siab, cov ntaub ntawv yuav tsum muaj cov khoom siv roj txaus txaus, xws li cov ntaub ntawv roj hlau hauv cov hlau siab, uas yog qhov tsim nyog dua.

3. Valve qhib thiab kaw zaus: thaum lubNpauj Npaim ValveQhib thiab kaw nquag, cov khoom yuav tsum tau hnav-resistant thiab qaug zog tiv taus. Nitrile Roj Hmab (NBR) tau hnav zoo thiab haum rau cov sijhawm zoo li no.

4. Xaiv qhov nqi: Xaiv cov ntaub ntawv tsawg los txo tus nqi thaum lub rooj sib tham xav tau. Cov ntaub ntawv roj hmab zoo tib yam muaj tus nqi qis, thaum kev ua haujlwm siab engineering plastics lossis cov khoom siv hlau khi muaj cov nqi siab.

Cov Yam Khoom Siv Cov Khoom Siv

1. Roj hmab: Nitrile Butadiene roj hmab (NBR) yog cov roj uas tsis kam, tab sis tsis txaus ntseeg, thiab kev tiv thaiv qis dua rau cov roj-℃ -120 ℃ thiab siab tsis dhau 1.6MPA; Fluororubber (FKM) tiv thaiv cov kub, roj, thiab tshuaj lom neeg corrosion, tab sis nws yog kim thiab muaj tsis zoo elasticity. Nws haum rauNpauj Npaim Li QubHauv kev lag luam thiab kev lag luam kws tshuaj uas muaj kev ntxhov siab txij li -20 ℃ txog 200 ℃; Ethylene propylene roj hmab (EPDM) yog dej-resistant, ozone resistant, laus resistant, thiab muaj cov roj tsis zoo. Nws yog qhov haum rau dej thiab dej tawm iformio ib puag ncig ntawm -50 ℃ rau 150 ℃.

2. Cov: Polytetrafluoroethylene (PTFE) muaj cov tshuaj ruaj khov zoo, thiab cov kev sib txhuam kub zoo, tab sis tsis muaj zog elastic thiab tsawg dua kev siv zog. Nws yog qhov haum rau cov xov xwm muaj zog hauv cov xov xwm muaj zog xws li ntawm -180 ℃ rau 250 ℃; Polyamide (PA) muaj lub zog siab, tawv, thiab cov roj tsis kam, thiab nws muaj cov dej nqus thiab cov khoom tsis zoo. Nws yog qhov haum rau nruab nrab thiab roj qis roj muaj cov xov xwm tawm tshiab xws li ntawm -40 ℃ rau 100 ℃.

3. Cov hlau: stainless hlau muaj lub zog siab, kev ua haujlwm siab, tab sis cov nqi siab thiab kev ua haujlwm siab, haum siab, muaj kev kub ntxhov siab; Tooj liab alloy muaj zoo thermal conductivity, thiab corrosion kuj, thiab yog ib qho yooj yim rau cov txheej txheem. Txawm li cas los xij, nws muaj lub zog tsawg thiab muaj feem ntau rau oxidation thaum kub. Nws yog haum rau npauj npaim valve salarios nrog qhov kub tsawg thiab siab xav tau thiab ua haujlwm.
