Rau kev teeb tsa lub iav iav hauv lub cev, cov khoom tshwj xeeb yog siv los muab kev sib khi, kho thiab damping - seals.Nyeem tag nrho txog cov iav ntim, lawv hom, tsim qauv thiab cov yam ntxwv, nrog rau kev xaiv thiab hloov cov ntsiab lus hauv tsab xov xwm.
Dab tsi yog iav foob
Lub iav foob yog cov khoom siv roj hmab nyob rau hauv daim ntawv ntawm daim kab xev tshwj xeeb uas tsim los rau mounting (kho thiab sealing) lub iav tsheb hauv kev khi
Txhawm rau tiv thaiv lub tsheb sab hauv lossis qhov ntim sab hauv ntawm lub tsev ntawm cov khoom siv tsheb los ntawm qhov tsis zoo ib puag ncig thaum tswj qhov tsim nyog pom, tsom iav siv - cua, rear, sab thiab lwm yam.Thaum lub sijhawm ua haujlwm ntawm lub tsheb, lub iav yuav tsum muaj qhov tseem ceeb thiab sib txawv ntawm kev vibration loads, shocks thiab shocks, yog li lawv yuav tsum muaj nruj haum rau hauv kev sib khi tsim los ntawm lub cev, thiab tib lub sijhawm muaj kev co decoupling nrog lub cev. .Tag nrho cov no yog ua kom ntseeg tau los ntawm kev siv cov khoom tshwj xeeb - roj hmab iav seals.
Lub iav foob ua ntau yam haujlwm:
● Kho cov iav hauv lub qhov rais npog;
● Damping ntawm vibrations, shocks thiab shocks kis mus rau iav los ntawm lub cev;
● Iav foob - tiv thaiv kev nkag mus ntawm huab cua (thiab gases feem ntau), dej, av, plua plav thiab cov khoom me me ntawm qhov chaw ntawm lub khob nrog lub cev;
● Muab qhov tsim nyog zoo nkauj;
● Nyob rau hauv cov qhov rais uas ua lub luag hauj lwm ntawm qhov kev tawm thaum muaj xwm ceev - xyuas kom meej lub dismantling ceev ntawm iav los ntawm kev khi.
Cov iav ntsaws ruaj ruaj ua rau muaj txiaj ntsig zoo rau kev ua haujlwm ib txwm ntawm lub tsheb, tsheb laij teb, tshwj xeeb thiab lwm yam khoom siv, muab kev nplij siab hauv chav tsev lossis hauv tsev.Lub foob puas los yog poob yuav tsum tau hloov sai li sai tau, tab sis ua ntej mus rau lub khw rau lub foob tshiab, koj yuav tsum muaj tsawg kawg yog ib qho kev nkag siab me ntsis ntawm hom ntawm cov khoom no, lawv cov qauv tsim thiab cov yam ntxwv.
Ntaus, hom thiab nta ntawm iav seals
Tag nrho cov iav ntsaws ruaj ruaj muaj cov qauv tsim zoo ib yam: nws yog cov hlua roj hmab (sib cais lossis kaw) ntawm cov ntaub ntawv nyuaj, uas yog ntsia rau sab nraud ntawm ntug ntawm lub cev, thiab sab hauv tuav lub iav.Lub foob yog tsim los ntawm ntau hom roj hmab, uas sib txuas ua ke siab elasticity, tsis kam mus rau qhov kub thiab txias, dej thiab roj nruj nruj, siab zog.
Iav seals raug cais raws li ntau yam kev cai - lub hom phiaj, txoj kev teeb tsa, hom profile thiab cov haujlwm tshwj xeeb.
iav foob profiles
Raws li lub hom phiaj, seals yog:
● Rau lub qhov rais;
● Rau lub qhov rais rear thiab tailgate;
● Rau cov qhov rais sab poob;
● Rau sab rigidly ntsia iav;
● Rau hatches;
● Rau cov iav uas ua haujlwm thaum muaj xwm txheej ceev.
Cov ntsaws ruaj ruaj rau cov iav sib txawv sib txawv ntawm qhov loj, tsim nta, kev teeb tsa thiab profile.
Tag nrho cov ntsaws ruaj ruaj (nrog rau kev zam ntawm cov ntsiab lus rau qis sab qhov rais) yog ob hom tsim:
● Kaw (ntiv nplhaib) thiab sib cais rau cov qauv tsheb tshwj xeeb;
● Split universal.
Thawj pab pawg muaj xws li cov khoom siv roj hmab uas tsim los rau nruab qhov cua ntawm lub tsheb ntawm ib qho qauv lossis qauv ntau yam.Xws li cov ntsaws ruaj ruaj muaj ib tug tshwj xeeb configuration, lawv kuj muaj peev xwm muaj ib tug tej yam profile uas coj mus rau hauv tus account tus yam ntxwv ntawm lub iav thiab lub cev qhov chaw nyob rau hauv kev sib cuag nrog nws.Cov pab pawg thib ob suav nrog cov khoom siv uas tuaj yeem siv rau ntau yam khoom siv, feem ntau cov tsheb npav, tsheb thauj khoom, tsheb laij teb, thiab lwm yam.
Muaj peb hom sab qhov rais seals:
● Main (sab sauv) - ntsia rau sab sauv ntawm lub qhov rais npog, tuav lub hauv ntej thiab nram qab, muab sealing ntawm lub qhov rais;
● Sab hauv sab nraud - ntsia rau hauv qab ntawm qhov khi los ntawm nws sab nrauv, tiv thaiv cov kab noj hniav sab hauv ntawm lub qhov rooj los ntawm dej, plua plav thiab av;
● Sab hauv sab hauv - ntsia rau hauv qab ntawm txoj hlua khi los ntawm nws sab hauv.
Cov ntsaws ruaj ruaj hauv qab kuj ntxuav cov iav ntawm cov av.Qhov no yog ua kom ntseeg tau los ntawm kev siv cov ntaub los yog txhuam mos nrog ib tug luv luv tub sab rau saum npoo ntawm sealant, rau qhov tsim no feem ntau hu ua velvets.
Cov ntsaws ruaj ruaj yog ntsia rau ntawm qhov tshwj xeeb protrusions (flanges) ntawm lub qhov rais npog, tsim rau ntawm lub cev, tuav lub iav hauv qhov zawj muab rau qhov no.Fixation ntawm lub foob yog muab nyob rau hauv ob txoj kev:
● Vim nws tus kheej elasticity;
● Vim lub auxiliary spacer ib feem - lub xauv.
Scheme ntawm sealing lub qhov rais sab ntawm lub tsheb
Thawj txoj kev yog siv los txhim kho cov ntsaws ruaj ruaj ntawm luv luv, feem ntau - cov ntsaws ruaj ruaj ntawm sab qis qhov rais.Cov khoom zoo li no tau muab tso rau ntawm flange ntawm txoj hlua khi, crimping rau ob sab, qee zaum ntxiv protrusions yog siv uas tau ntsia rau hauv lub qhov.
Xauv nrog lub xauv yog siv rau hauv tag nrho lwm cov ntsaws ruaj ruaj.Nyob rau hauv cov ntaub ntawv no, lub foob muaj ob feem: ib tug sealing daim kab xev thiab ib tug pab daim kab xev ntawm me me cross-section.Lub sealing daim kab xev yog ntsia rau ntawm lub qhov rais binding thiab tuav lub iav, thiab lub xauv yog muab tso rau hauv ib tug tshwj xeeb zawj nyob rau hauv lub ntsiab daim kab xev - nws ua raws li ib tug wedge uas xyuas kom meej lub spacer ntawm lub foob thiab jamming lub iav.
Nyob rau hauv cov ntsaws ruaj ruaj rau lub qhov rais uas ua lub luag hauj lwm ntawm ib tug thaum muaj xwm ceev tawm, lub xauv yog nyob rau ntawm ib sab ntawm cov neeg nrog caij compartment kom dawb nkag tau rau nws.Txhawm rau tshem tawm lub xauv nrawm, lub nplhaib hlau txuas nrog nws yog muab - los ntawm rub lub nplhaib no, koj tuaj yeem tshem lub xauv, vim tias lub foob yuav xoob thiab lub iav tuaj yeem yooj yim nyem tawm lossis rub mus rau hauv cov neeg caij tsheb, qhib lub qhov rais tawm.
Kev txhim kho ntawm tag nrho cov iav seals yog ua kom ntseeg tau los ntawm kev muab lawv hla ntu ntawm cov duab nyuaj.Feem ntau, qhov profile muaj ntau qhov ntev grooves, ridges thiab ncaj los yog nkhaus nto ua haujlwm ntau yam:
● Groove rau flange ntawm lub qhov rais npog;
● Groove hauv qab ntawm ntug iav;
● Groove hauv qab lub xauv;
● Sab nrauv kho kom zoo nkauj nto;
● Sab hauv kho kom zoo nkauj nto;
● Groove thiab nto rau mounting ib tug hniav thav duab;
● Ntxiv grooves thiab ridges kom paub meej cov yam ntxwv tsim nyog ntawm lub foob.
