Cov ntaub ntawv raw khoom (tshwj xeeb lub npe yog polytetrafluoroethylene) yog ib qho khoom siv feem ntau siv hauv cov dej cua sov, siv rau kev sib txuas ntawm cov yeeb nkab fittings, los txhim kho kev sib khi ntawm cov yeeb nkab txuas. Raw pluas noj siv yog ib qho tshiab thiab zoo tagnrho sealing khoom. Vim nws tsis muaj tshuaj lom, tsis qab, zoo heev sealing, rwb thaiv tsev, corrosion kuj, nws yog dav siv nyob rau hauv kev kho dej, natural gas, tshuaj, yas, Electronic Engineering thiab lwm yam teb.
Hauv peb lub neej niaj hnub, qee zaum peb nruab lub kaum sab xis, kais dej, kav dej, thiab lwm yam los ntawm peb tus kheej. Thaum peb qhwv cov ntaub ntawv raw khoom, nws ib txwm tsis qhwv zoo. Cov kais dej ib txwm xau thiab seeps. Dab tsi yog qhov teeb meem? Yuav ua li cas peb qhwv cov ntaub ntawv raw khoom?
1. Ntxuav lub cev txawv teb chaws nyob rau hauv qhov sib txuas ntawm cov khoom siv raw siv ua ntej, thiab tom qab ntawd cua nws sab hauv raws li sab nrauv ntawm cov yeeb nkab qhib.
2. Ua tib zoo saib cov kev taw qhia ntawm winding. Coj lub kaum sab xis valve ua piv txwv. Thaum lub kaum sab xis yog screwed rau hauv phab ntsa, nws tig clockwise mus rau sab xis. Tom qab ntawd peb qhwv cov khoom siv raw khoom ntawm lub kaum sab xis valve nyob rau hauv kev coj ntawm counterclockwise mus rau sab laug. Nyob rau hauv txoj kev no, lub tighter lub kaum sab xis valve yog, thiab nws yuav tsis xoob. Kev ceev faj yuav tsum tau them rau cov khoom siv raw khoom tsim thaum lub sij hawm winding txheej txheem kom paub meej tias cov xov paj ntaub yog qhwv tag nrho los ntawm cov khoom siv raw.
3. Thaum qhwv, ceev cov khoom siv raw khoom siv, kom cov khoom siv raw siv nruj nreem rau cov xov, kom nruj raws li qhov ua tau, tsis txhob xoob lub qhwv, qhwv nrog ib txhais tes kom nruj lub voj voog, koj tuaj yeem nruj thaum qhwv. Qhwv ib ncig ntawm 2-3 voj voog. Tom qab ua tiav, cov npoo ntawm cov hlau ntug yog me ntsis thicker dua li ntawm sab hauv ntawm lub qhov ncauj lo lo ntxhuav.
4. Raws li rau winding "ob peb txheej" yam tsis muaj kev txwv nruj, yuav tsum tau nruj, tsis muaj to raws li tus qauv, tab sis raws li kev paub, feem ntau yuav tsum tau winding ntau tshaj li kaum lub voj voog kom paub meej sealing nyhuv. Thaum winding tiav lawm, siv lub nplhaib ntiv tes los tuav nws, kom nws haum zoo kawg nkaus nrog cov xov paj ntaub.
5. Thaum ntsia hlau, tsis txhob ntsia hlau kom tuag. Nws tsis tas yuav tsum tau screwed mus rau qhov chaw uas nws tsis tuaj yeem screwed. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau qhov tob ntawm cov ntsia hlau hauv, xws li cov dej kub thiab dej txias sib tov valve ob khoov taw tiv thaiv cov hlau, thaum ntsia hlau, yuav tsum tau them nyiaj rau kev tswj qhov kev ncua deb ntawm phab ntsa, tshwj xeeb tshaj yog nyob rau hauv phab ntsa. ntawm ob sab hauv hlau khoov qhov tob tsis zoo ib yam. Tuav lub qhwv lub connector thiab tig nws nyob rau hauv clockwise kev taw qhia.
Txhawm rau kom tsis txhob muaj dej ntws tawm thiab nkag mus ntawm cov yeeb nkab sib txuas, ntxiv rau kev paub qhov tseeb winding txoj siv raw khoom, thiab siv cov khoom siv raw khoom siv, cov khoom siv raw ntawm Beibei whale yog tsim nyog yuav khoom thiab siv yam xyuam xim.
