Taw qhia: Nkag siab txog kev sib khi siab
Sealing siab yog qhov tseem ceeb tab sis feem ntau nkag siab yuam kev hauv kev tsim cov roj hmab sealing. Txawm tias muaj cov khoom siv roj hmab zoo thiab qhov tawv tawv, tsis txaus los yog lub siab sealing ntau dhau tuaj yeem ua rau cov dej xau, nrawm hnav, lossis qhov tsis zoo ntawm lub foob.
Hauv cov ntsiab lus yooj yim, sealing siab hais txog qhovtiv tauj siab generated ntawm cov roj hmab foob thiab mating nto. Lub siab no yuav tsum muaj siab txaus los thaiv cov dej los yog cov pa roj, tseem tswj tau kom tsis txhob ua rau lub foob foob lossis cov khoom nyob ib puag ncig.
Yuav ua li cas sealing siab yog tsim nyob rau hauv roj hmab foob

Hu rau Kev Ruaj Ntseg Los Ntawm Roj Hmab DeformationTsis zoo li cov ntaub ntawv nruj, cov roj hmab ntsaws ruaj ruaj tsim sealing siab los ntawm elastic deformation. Thaum compressed thaum lub sij hawm kev teeb tsa, cov roj hmab sim rov qab mus rau nws cov duab qub, tsim kom muaj kev sib cuag tsis tu ncua tiv thaiv qhov chaw sib khi.
Tsim kom zoo groove thiab tswj compression yog qhov tseem ceeb kom ua tiav qhov ruaj khov thiab zoo sealing siab. |
Yam tsawg kawg nkaus Sealing Pressure: Tiv thaiv kom tsis muaj dej
Txhua lub foob roj hmab yuav tsum muaj qhov tsawg kawg nkaus sealing siab kom ua haujlwm zoo. Qhov siab tsawg kawg nkaus no yuav tsum tshaj qhov siab hauv lub cev nrog rau kev them nyiaj rau qhov roughness, tolerances, thiab muaj peev xwm hloov pauv.
Yog tias sealing siab tsawg dhau lawm, cov roj hmab yuav tsis ua raws li tag nrho cov mating nto, tso cai rau micro-kawg txoj hauv kev los tsim. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov roj sealing thiab tsawg - cov kua dej viscosity.
Hauv kev xyaum, qhov tsawg kawg nkaus sealing siab nyob ntawm seb yam xws li kev khiav hauj lwm siab, hom xov xwm, kub, thiab nto tiav.
Sealing Pressure vs Roj Hmab Hardness (Shore A)

Sib npaug Hardness thiab kev sib cuag siabRoj hmab hardness muaj qhov cuam tshuam ncaj qha rau kev sib khi. Softer roj hmab tebchaw tsim sealing siab yooj yim dua nyob rau hauv qis compression, thaum lub zog sib txuas yuav tsum muaj zog compression ntau dua kom ua tau zoo tib yam kev sib cuag.
Rau feem ntau static sealing daim ntaub ntawv, roj hmab nyob rau hauv 60-70 Shore A ntau muab qhov zoo tshaj plaws sib npaug ntawm sealing siab, durability, thiab installation kev ruaj ntseg. |
System Pressure vs Sealing Pressure
Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm qhov system siab thiab sealing siab. Lub kaw lus siab yog hais txog lub siab sab hauv ntawm cov kua lossis roj tau kaw, thaum lub sealing siab yog qhov sib tiv tauj los ntawm cov roj hmab foob.
Nyob rau hauv zoo- tsim cov ntsaws ruaj ruaj, sealing siab yuav tsum nyob twj ywm siab tshaj qhov system siab nyob rau hauv tag nrho cov kev khiav hauj lwm tej yam kev mob. Qee qhov xwm txheej, lub zog siab tuaj yeem pab txhawb lub foob, tab sis dhau - kev cia siab rau qhov kev cuam tshuam no tuaj yeem ua rau tsis muaj kev ruaj ntseg lossis extrusion.
Common Sealing Pressure yuam kev
Kev tswj tsis raug ntawm sealing siab yog ib qho ua rau lub foob tsis ua haujlwm. Cov kev ua yuam kev xws li dhau - compression, uas ua rau cov compression ntau dhau lawm, thiab nyob rau hauv - compression, uas ua rau xau.
Lwm qhov teeb meem tsis tu ncua suav nrog kev xaiv qhov tsis sib haum xeeb, kev tsim cov zawj tsis zoo, thiab tsis quav ntsej txog thermal expansion cuam tshuam uas hloov kev sib khi siab thaum ua haujlwm.
Xaus: Optimizing Sealing Pressure rau Kev Ua Tau Zoo
Sealing siab yog qhov tseem ceeb hauv kev ua haujlwm ntawm roj hmab foob. Kev ua tiav qhov raug sealing siab yuav tsum muaj kev sib npaug uas suav nrog roj hmab hardness, compression ratio, groove tsim, thiab kev ua haujlwm.
Tsis yog qhov ua kom muaj zog, lub hom phiaj yog tsimruaj khov, txaus, thiab tswj kev sib cuag siabuas ua kom ntev - lub sij hawm sealing yam tsis ua puas rau cov roj hmab los yog ib puag ncig cov khoom.
