Hais txog kev sib tov roj hmab sealing nplhaib
Kev ua haujlwm ntawm cov khoom sib tov roj hmab sealing nplhaib yog los tiv thaiv qhov nruab nrab to thiab tswj kev ruaj ntseg ntawm txoj haujlwm sealing. Nws feem ntau yog ntsia rau ntawm qhov chaw sib khi ntawm lub agitator ncej thiab cov ntaub ntawv nyob ze nrog lub ncej kom tiv thaiv qhov nruab nrab los ntawm txoj hauj lwm sealing. Cov roj hmab sealing nplhaib muaj qee yam deformation muaj peev xwm thiab resilience, uas tuaj yeem hloov mus rau kev sib hloov ntawm cov khoom sib tov thiab tuav cov nyhuv sealing.
Thaum siv cov khoom siv roj hmab sib tov, yuav ua li cas xaiv cov khoom, thiab yuav ua li cas rau nruab, tswj, thiab hloov nws?
- Kev xaiv cov khoom siv: Raws li qhov nruab nrab thiab kev ua haujlwm, xaiv cov khoom siv roj hmab nrog cov tshuaj lom neeg zoo, hnav tsis kam, thiab kub-resistant. Cov khoom siv roj hmab muaj xws li styrene-butadiene roj hmab (NBR), fluorine roj hmab (FKM), thiab silicone roj hmab (VMQ).
- Kev txhim kho kom raug: Xyuas kom tseeb tias cov roj hmab sealing nplhaib yog raug ntsia rau ntawm txoj hauj lwm sealing ntawm lub tov khoom thiab cov ntaub ntawv nyob ze nrog lub ncej. Ceev faj kom tsis txhob muaj kev sib tsoo ntau dhau los yog cuam tshuam ntawm lub nplhaib roj hmab sealing, uas yuav cuam tshuam rau nws txoj kev sib khi.
- Kev tu thiab hloov pauv: Txheeb xyuas cov roj hmab foob tsis tu ncua rau kev hnav thiab kev laus. Yog tias pom muaj teeb meem xws li hnav, tawg lossis tawv tawv, hloov lub nplhaib sib khi hauv lub sijhawm kom ntseeg tau tias kev sib khi ua haujlwm thiab kev ua haujlwm ruaj ntseg ntawm lub tshuab tov khoom.
- Lubricant siv: Raws li cov lus pom zoo ntawm Linde Polymer Hoobkas engineers, siv cov lubricants tsim nyog los txo cov kev sib txhuam ntawm cov roj hmab foob nplhaib thiab cov ncej thiab txhim kho cov nyhuv sealing.
Tom ntej no, nkag siab txog kev sib khi ntawm cov khoom sib xyaw hauv qab no feem ntau.
Foob ntawm lub tov khoom yog ib qho tseem ceeb ntawm cov khoom siv los xyuas kom meej tias lub tov khoom tsis xau tawm thaum ua haujlwm.
Nov yog qee qhov sib tov sib xyaw ua ke
- Roj Hmab Foob: Roj Hmab foob yog ib qho ntawm feem ntau thiab feem ntau siv txoj kev sib khi lub tov khoom. Nws feem ntau yog ua los ntawm cov roj hmab los yog cov khoom siv elastic thiab tau nruab rau hauv ib qho chaw kaw ntawm lub agitator ncej. Cov roj hmab sealing nplhaib muaj qhov zoo elasticity thiab corrosion kuj thiab tuaj yeem tiv thaiv qhov nruab nrab to.
- Mechanical seal: Mechanical seal yog ib txoj kev sib khi ntau dua. Nws muaj ntau yam khoom siv, suav nrog lub nplhaib sib khi, qhov chaw sib khi, qhov chaw sib txuas, thiab lwm yam. Lub tshuab foob tau hu rau lub nplhaib sib khi los ntawm lub nplhaib sealing thiab siv kev sib txhuam thiab kev sib txhuam ntawm qhov chaw sealing kom ua tiav cov nyhuv sealing. Mechanical seals feem ntau yog siv rau hauv kev siv agitator nrog kev kub siab, kub kub lossis kev tshaj tawm tshwj xeeb.
- Agitator npog: Qee qhov xwm txheej, kev sib khi ntawm cov agitator tuaj yeem ua tiav los ntawm kev siv lub npog npog. Lub agitator npog yog ib qho khoom siv uas npog rau sab saum toj ntawm lub agitator thiab tiv thaiv cov pa nruab nrab los ntawm kev tiv tauj lub sealing ntug ntawm lub thawv lossis lub tank. Cov npog npog feem ntau yog nruab nrog lub sealing gasket los yog roj hmab sealing nplhaib los xyuas kom meej sealing kev ua tau zoo.
Agitator roj hmab sealing nplhaib yog ib qho ntawm cov agitator sealing txoj kev thiab yog siv los xyuas kom meej lub sealing ntawm lub agitator ncej thiab lub sealing txoj hauj lwm. Roj hmab foob feem ntau yog ua los ntawm cov roj hmab lossis cov ntaub ntawv elastic thiab muaj cov tshuaj tiv thaiv zoo thiab elasticity.
Kev ua haujlwm ntawm cov khoom sib tov roj hmab sealing nplhaib yog los tiv thaiv qhov nruab nrab to thiab tswj kev ruaj ntseg ntawm txoj haujlwm sealing. Nws feem ntau yog ntsia rau ntawm qhov chaw sib khi ntawm lub agitator ncej thiab cov ntaub ntawv nyob ze nrog lub ncej kom tiv thaiv qhov nruab nrab los ntawm txoj hauj lwm sealing. Cov roj hmab sealing nplhaib muaj qee yam deformation muaj peev xwm thiab resilience, uas tuaj yeem hloov mus rau kev sib hloov ntawm cov khoom sib tov thiab tuav cov nyhuv sealing.
Thaum siv cov roj hmab sib tov sib xyaw, yuav ua li cas xaiv cov khoom, yuav ua li cas rau nruab, tswj, thiab hloov nws?
Kev xaiv cov khoom siv: Raws li qhov nruab nrab thiab kev ua haujlwm, xaiv cov khoom siv roj hmab nrog cov tshuaj lom neeg zoo, hnav tsis kam thiab kub-resistant. Cov khoom siv roj hmab muaj xws li styrene-butadiene roj hmab (NBR), fluorine roj hmab (FKM) thiab silicone roj hmab (VMQ).
