Vim li cas cov kev sib khi ua tau zoo ntawm pob li qub hloov nrog qhov kub?

Vim li cas cov kev sib khi ua tau zoo ntawmPob Li Qubsib txawv nrog kev hloov pauv kub?

Raws li cov tseem ceeb tswj tiv thaiv nyob rau hauv kev lag luam pipelines, kev ua yeeb yam ntawm pob khoom uas li qub cuam tshuam nrog kev nyab xeeb thiab kev ntseeg tau ntawm lub system. Txawm li cas los xij, hauv cov ntawv thov siv, cov nyhuv uas sib txawv ntawm cov khoom hloov pauv ntau dua vim yog cov yam ntxwv tsim qauv, thiab kev yoog raws li cov kev ua haujlwm.

1. Qhov sib txawv ntawm cov kev nthuav dav ci coefficients ntawm cov khoom sib khi

Cov qauv sib khi ntawmPob Li QubFeem ntau yog muaj kev sib xyaw ntawm cov ntaub ntawv hlau valve thiab cov ntaub ntawv mosaling (xws li PTFE, nylon) lossis cov ntsaws ruaj ruaj. Thaum qhov kub nce ntxiv, qhov sib txawv coefficients ntawm thermal expansion ntawm cov khoom sib txawv tuaj yeem ua rau kev hloov pauv ntawm qhov sib txawv. Piv txwv li, PTFE sealing ib ncig tej zaum yuav thim tawm ntawm qis kub, uas yuav ua rau xau; Kev hnav ntau dhau ntawm qhov kub siab yuav ua rau hnav ua si ntau thiab txawm tias ua rau lub pob kom tau daig. Txawm hais tias lub pob hluav taws xob sib npaug yuav tiv thaiv kom sov dua, qhov sib txawv hauv cov hluav taws xob ntawm lub tog raj ntawm cov npoo av, sib sau micro xau channel.

2. Tus cawv ntawm qhov kub thiab txias ntawm kua media

Hloov kho qhov kub thiab txias tuaj yeem hloov kho lub cev ntawm lub cev, xws li theem, yog li cuam tshuam rau kev sib khi ua tau zoo ntawm pob li qub. Nyob rau hauv cov kev mob siab tsawg, nruab nrab yuav ua solorify lossis crystallize, thaiv cov chaw sib khi; Kev kub siab tshaj xov xwm yuav txo cov hardness ntawm cov ntaub ntawv sealing thiab ua kom muaj kev laus. Piv txwv li, hauv chav dej, chav dej kub tau ua rau cov dej khov kho, thaum ua rau cov khoom sib khi, ua rau muaj cov khoom noj thiab kaw.

3. Cov qauv hloov tsis muaj txiaj ntsig hauv cov qauv tsim qauv

Qee lub pob valve tsim tsis tau txiav txim siab qhov ntsuas kub. Piv txwv li, yog lub rooj zaum kev sib pab ntawm lub pob ruaj khov, nws tsis tuaj yeem hloov kho cov lus sib piv thaum qhov kub hloov pauv, ua rau kev ua haujlwm tsis ua haujlwm. Txawm hais tias ntab npas muaj peev xwm them rau sealing factional los ntawm pob hluav taws kub, uas tuaj yeem ua rau lub foob. Tsis tas li ntawd, pob li qub sib txuas nrog los ntawm vuam yog nquag mus deformation vim muaj kev kub ntxhov siab ntawm qhov kub, ntxiv exacerbating kev pheej hmoo ntawm kev xau.

Kev daws: Rau kev ua haujlwm siab ua haujlwm, cov khoom siv hlau nyuajPob Li Qubtuaj yeem xaiv thiab lub qhov hluav taws xob lub caij nplooj ntoo tsim tsim muaj peev xwm yuav tau ua kom zoo. Tsawg kawg cov xwm txheej xav tau kev siv cov ntaub ntawv tiv thaiv brittle brittle brittle brittle plhuav (xws li sumreing nto smoothness. Nyob rau tib lub sijhawm, tsis tu ncua kev sib khi ua tau zoo ntawm pob khoom ntawm cov tsheb ciav hlau raws li cov kab mob siab raws li cov cuab yeej siv lub neej.
