Dab tsi yog txoj kev xau ntawm lub nplhaib sealing? Vim li cas thiaj muaj qhov xau?

Sij hawm: 2021-11-25 Hits: 7

Muaj ntau ntau hom sealing nplhaib khoom nyob rau hauv kev ua lag luam, uas yog txaus rau dazzle buyers. Muaj ntau hom thiab tsis sib xws. Xaiv lub nplhaib foob cov khoom tsis zoo ib txwm muaj

tsis tuaj yeem coj peb qhov kev cia siab sealing nyhuv. Ob qho khoom siv thiab cov qauv tseem ceeb heev rau qhov zoo ntawm lub nplhaib sealing.


Cov khoom lag luam zoo sealing feem ntau muaj lub ntsej muag ci thiab huv si yam tsis muaj adhesion, npuas, burrs, thiab lwm yam, thiab tsis muaj cov khoom siv los yog tawg hauv qhov zoo, thiab qhov loj yuav tsum. 

kuj ua tau raws li cov qauv thiab cov neeg siv khoom xav tau. Xaiv lub nplhaib foob zoo tuaj yeem pab cov neeg siv kom txo tau qhov kev pheej hmoo ntawm kev xau. Cov ntsiab lus hauv qab no piav qhia meej ntau lub nplhaib sib khi 

Txoj kev xau thiab ua rau kom tawg:

Feem ntau cov leaks ntawm sealing rings tau muab faib ua plaub hom: interface to, penetration to, diffusion to, thiab puas to.


Interface leak

Vim tsis txaus compression ntawm lub gasket, tsis zoo smoothness los yog deformation ntawm lub interface tiv tauj nto yuav ua rau ib tug tej yam npaum li cas ntawm leakage ntawm lub sealing interface.


Nkag nkag

Vim tias cov ntaub ntawv mos feem ntau yog fibers, lawv tau yooj yim infiltrated los ntawm nruab nrab, tshwj xeeb tshaj yog nyob rau hauv qhov kev txiav txim siab. Vim lub capillary tshwm sim, qhov nruab nrab yuav nkag mus rau hauv 

tsis tshua muaj siab sab, yog li kev nkag mus yuav tshwm sim.


Diffusion xau

Diffusion leakage yog hais txog kev xau los ntawm cov khoom xa tuaj ntawm qhov nruab nrab los ntawm kev sib khi los yog lub raj capillary ntawm cov khoom sealing nyob rau hauv lub impetus ntawm cov concentration.

txawv. Diffusion yog qhov tshwm sim ntawm molecular motion thiab feem ntau tsis yog ib txoj kev. Nyob rau hauv ib lub xeev uas qhov sib txawv ntawm sealing siab yog heev me me los yog nyob rau hauv lub nqus tsev vacuum, nws yog tsim nyog los them 

ua tib zoo saib xyuas qhov tshwm sim ntawm ob hom kev xau, xws li nkag mus thiab diffusion, kom yooj yim permeable tshuaj xws li nitrogen thiab hydrogen, thiab cov tshuaj lom neeg thiab cov xov tooj cua.


Kev puas tsuaj

Qhov chaw ua haujlwm ntawm qhov sealing yog qhov hnyav, thermal deformation kuj loj, thiab nws feem ntau raug kev co, kev cuam tshuam, kev teeb tsa tsis raug, kev nruj nruj heev, rov ua dua.

siv, compression deformation, nyob rau hauv kev ntxhov siab concentration, kev puas tsuaj tshaj lub zog qaug zog, thiab cov khoom aging Tej xwm txheej xws li, deterioration, thiab lwm yam. yuav ua rau puas ntsoog. Xws li cov xau feem ntau yog

hnyav dua, thiab qhov cuam tshuam yuav loj dua. Nws yog ib qho tsim nyog los txhawb kev tiv thaiv.
