PTFE daim kab xev, tseem hu ua polytetrafluoroethylene daim kab xev, yog dav siv nyob rau hauv ntau yam sealing xav tau kev pab nyob rau hauv kev kub siab thiab kub ib puag ncig vim nws ua tau zoo heev. Txhawm rau kom ntseeg tau tias qhov ua tau zoo tshaj plaws thiab kev pabcuam lub neej ntev tshaj plaws ntawm PTFE daim kab xev, txoj kev siv kom raug yog qhov tseem ceeb. Cov hauv qab no yog qhov tseeb siv PTFE daim kab xev:
I. Kev npaj
1. Ntxuav lub ntsej muag: Ua ntej siv PTFE daim kab xev, qhov saum npoo yuav tsum tau muab kaw kom huv si kom paub meej tias nws tsis muaj roj, plua plav lossis lwm yam impurities. Qhov no yuav pab txhim kho qhov adhesion thiab sealing nyhuv ntawm daim kab xev.
2. Txheeb xyuas qhov chaw ntawm qhov chaw: xyuas kom meej tias qhov chaw sealing yog tiaj tus, tsis muaj kev puas tsuaj los yog tsis sib xws kom tsis txhob cuam tshuam cov nyhuv ntawm daim kab xev.
II. Txiav daim kab xev
Raws li qhov loj ntawm qhov yuav tsum tau muab khi, tsim nyog txiav PTFE daim kab xev. Thaum txiav, sim ua kom cov npoo ntawm daim kab xev kom tsis txhob burrs lossis puas.
III. Wrapping daim kab xev
1. Wrapping kev taw qhia: Feem ntau, kev taw qhia winding ntawm PTFE daim kab xev yuav tsum yog tib yam li cov kev taw qhia nruj ntawm cov xov. Qhov no ua kom cov ntaub nplaum yuav tsis xoob lossis plam thaum nruj.
2. Tus naj npawb ntawm cov khaubncaws sab nraud povtseg: Raws li cov kev cai tshwj xeeb sealing, kho cov txheej txheem winding kom tsim nyog. Feem ntau hais lus, winding 2-3 txheej tuaj yeem ua tiav cov txiaj ntsig zoo.
3. Uniform winding: Thaum lub sij hawm winding txheej txheem, qhov nro ntawm daim kab xev yuav tsum tau khaws cia zoo li ntau li ntau tau kom tsis txhob muaj wrinkles los yog qhov khoob. Qhov no xyuas kom meej tias daim kab xev haum nruj nrog lub sealing nto thiab txhim kho cov nyhuv sealing.
IV. Installation thiab zawm
1. Kev teeb tsa txoj haujlwm: Txhim kho cov khoom ntim nrog PTFE daim kab xev mus rau txoj haujlwm tshwj xeeb kom ntseeg tau tias lawv raug ua raws li cov khoom siv docking.
2. Kev nruj nruj: Thaum lub sij hawm zawm txheej txheem, lub zog yuav tsum tau tswj me ntsis kom tsis txhob nruj nruj heev uas ua rau cov ntaub nplaum raug nyem, deformed lossis ruptured. Lub zog nruj me ntsis tuaj yeem ua kom muaj kev sib khi ua haujlwm thiab kev pabcuam lub neej ntawm daim kab xev.
V. Kev tshuaj xyuas thiab tu
1. Txheeb xyuas cov nyhuv sealing: Tom qab kev teeb tsa, ua tib zoo xyuas seb puas muaj cov dej xau hauv qhov sealing. Yog tias pom muaj cov dej xau, PTFE daim kab xev yuav tsum tau rov ua dua lossis hloov lub sijhawm.
2. Kev saib xyuas tsis tu ncua: Thaum siv, qhov xwm txheej ntawm PTFE daim kab xev yuav tsum tau kuaj xyuas tsis tu ncua, thiab cov plua plav lossis roj ntawm qhov chaw yuav tsum tau ntxuav kom huv si raws sijhawm. Yog tias daim kab xev pom tias muaj hnub nyoog, deformed lossis puas, nws yuav tsum tau hloov nrog daim kab xev tshiab raws sijhawm.
VI. Cov kev ceev faj
1. Tsis txhob overheating: Txawm hais tias PTFE daim kab xev yog resistant rau high kub, overheating yuav tsum tau zam thaum siv kom tsis txhob degradation los yog decomposition ntawm daim kab xev.
2. Tsis txhob kov cov khoom ntse: Thaum siv thiab khaws cia, PTFE daim kab xev yuav tsum tau tiv thaiv los ntawm kev sib cuag nrog cov khoom ntse kom tsis txhob khawb lossis ua rau daim kab xev puas.
3. Cia ib puag ncig: PTFE daim kab xev yuav tsum muab khaws cia rau hauv qhov chaw qhuav thiab txias, tsis txhob tshav ntuj ncaj qha thiab qhov chaw ntub dej.
Hauv cov ntsiab lus, kev siv PTFE daim kab xev kom raug suav nrog kev npaj, txiav daim kab xev, winding daim kab xev, kev teeb tsa thiab kev nruj, kev tshuaj xyuas thiab kev saib xyuas, thiab kev ceev faj. Los ntawm kev ua raws li cov kauj ruam no thiab ceev faj, qhov ua tau zoo tshaj plaws thiab kev pabcuam lub neej ntev tshaj plaws ntawm PTFE daim kab xev tuaj yeem ua kom tau raws li qhov xav tau ntawm kev sib khi hauv ntau qhov chaw siab thiab kub kub.
