PTFE lub cevtau pib siv hauv automotive sector thiab sai sai tau nrov.Hoses ua los ntawm polytetrafluoroethylene ua tau zoo dua li cov roj hmab hose hauv kev siv tsheb vim nws muaj kev lag luam siab thiab nws cov kev ua tau zoo heev, yog li lawv cov kev lag luam siv hauv tsheb tau nce siab.
PTFE hose yog dab tsi?
PTFE hose yog ib lub raj tsim los ntawm ib sab hauv PTFE hauv ob sab phlu thiab ib txheej stainless hlau braided txheej raws li kev tiv thaiv npog.PTFE liner zoo ib yam li PTFE raj nrog rau sab nraud tiv thaiv npog, ua rau nws lub siab tsis kam, raws li tsheb siv rau PTFE hose.
Dab tsi yog cov khoom ntawm PTFE hose?
Chemical inert, sib haum rau ntau hom roj
Tsawg permeability
Tsawg coefficient ntawm kev sib txhuam
Lub teeb nyhav
Tsis nplaum
Tsis-wettingl
Tsis-flammable
Huab cua / aging kuj
Cov khoom hluav taws xob zoo heev
PTFE lined roj hose - hom:
Virgin PTFE roj hose
Lub hose core rau nkauj xwbPTFE roj hoseyog ua los ntawm 100% PTFE resin tsis muaj pigment lossis additives.
Conductive (Anti-static)PTFE roj hose
Statically dissipative los yog tag nrho conductive rau dissipative tshem tawm ntawm static nqi cuam tshuam rau combustible kua hloov.Yuav kom khiav nrog E85 thiab Ethanol, los yog Methanol Roj, conductive PTFE puab core yog tsim nyog.
PTFE hose rau roj - kev xaiv:
PTFE braided hose nrog ib txheej SS - Ib qho ntawm PTFE roj hose nrov tshaj plaws
PTFE braided hose nrog ob chav SS txheej - txhawm rau ua kom lub siab rau qee yam kev siv
PTFE braided hose nrog SS txheej thiab dub Nylon npog - Zoo tiv thaiv rau stainless hlau txheej thiab puas kuj
PTFE braided hose nrog ib txheej SS thiab PVC coated - Zoo tiv thaiv rau stainless hlau txheej thiab ua rau nws zoo li fancier rau koj lub tsheb
Piv nrog roj hmab roj hose, vim li cas xaivPTFE roj hose?
PTFE roj kab yog ib qho zoo heev hloov rau roj hmab hose.Nrog rau txoj kev tsim khoom thiab vaj tsev nyob, lawv tuaj yeem ua tau ntev heev thiab yooj yim heev rau nruab rau hauv qhov system.Txawm hais tias lawv tsis muab tib yam elastic ntau yam ua los ntawm cov roj hmab, PTFE hoses yog cov resistant rau feem ntau cov tshuaj, thiab lawv tsis feem ntau tso pa tawm, uas yog ib qho tseem ceeb rau txhua yam ntawm qhov chaw nyob.Cov tshuaj tiv thaiv no kuj txhais tau tias PTFE hoses decompose qeeb qeeb dua li cov roj hmab hoses.
Qhov kev sib txhuam saum npoo ntawm PTFE kuj tseem qis dua li cov roj hmab, uas txhais tau hais tias tus nqi ntws tuaj yeem txhim kho los ntawm kev siv PTFE hose.Txawm hais tias cov roj hmab tau yooj yim decomposed ntawm huab cua kub, PTFE tiv taus kub kub, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau roj hose hauv kev sib tw tsheb.
Ua ntej, lubPTFE lub cevua raws li vapor barrier los tiv thaiv cov roj tsw qab los ntawm kev nkag mus rau hauv chav nres tsheb lossis khw muag khoom thiab hlawv thaum koj caij so.
Thib ob, PTFE-lined hose muaj cov tshuaj tiv thaiv siab tshaj plaws thiab txhawb nqa cov khoom siv hauv tsheb, uas tsis tuaj yeem ua tau nrog cov roj hmab zoo tib yam.Feem ntau yog cov roj av sib xyaw muaj ethanol.Lub cev roj hmab hoses decompose thaum lawv los rau hauv kev sib cuag nrog cov roj av no, thiab nws thiaj li decompose mus rau qhov chaw uas lawv yuav pib mus los yog txhaj roj-uas yog txaus ntshai heev.
Thib peb, PTFE lined hose muaj qhov kub thiab txias heev-qhov tseeb, qhov kub thiab txias ntawm lub hose muag los ntawm peb cov roj hose yog -60 degrees Celsius mus rau +200 degrees Celsius.Nws yog qhov tsim nyog los qhib cov yeeb nkab dej ntawm koj lub tsheb kis las.
Plaub, peb cov roj PTFE hose muaj kev ua haujlwm siab heev, rov xyuas kom meej tias koj tuaj yeem siv tau rau txhua hom kev siv tsheb.AN6 loj yog haum rau 2500PSI, AN8 loj yog haum rau 2000psi-txawm rau cov thov kev thov, muaj txaus siab
Dab tsi ntawm cov roj kab koj xav tau khiav nrog E85 thiab ethanol, lossis methanol roj?
Kev siv ethanol thiab methanol fuels tau dhau los ua neeg nyiam nyob rau hauv xyoo tas los no, tshwj xeeb tshaj yog nrog kev nce siab ntawm lub zog horsepower turbocharged supercharged xyaw.E85 los yog ethanol tau ua pov thawj tias yog cov roj siv hluav taws xob zoo uas tuaj yeem muab cov ntaub ntawv thov nrog octane ntsuas thiab lub zog muaj peev xwm.Tsis tas li ntawd, nws tseem tuaj yeem ua kom muaj qhov txias txias ntawm cov cua nkag.
Txawm li cas los xij, ethanol yog corrosive, qee zaum nws yuav tsim cov khoom zoo li gel, thiab tuaj yeem ua rau cov roj hluav taws xob puas tsuaj, txwv tsis pub nws yuav tsis cuam tshuam los ntawm cov roj av thiab cov roj sib tw.
Yuav tsum tau siv cov lim roj tshwj xeeb.Tau kawg koj yuav tsum xyuas kom meej tias koj lub twj tso kua roj tau sib xws, tab sis li cas txog cov roj kab?
PTFE hose tuaj yeem muab nrog stainless hlau braid thiab dub txheej.Qhov kev ua yeeb yam PTFE no siv cov hlua khi sab nraud thiab sab hauv PTFE liner, uas yog tiv taus cov tshuaj lom neeg thiab thermal decomposition.Cov xaim hluav taws xob yog qhov tseem ceeb rau kev siv thiab txiav txim siab seb puas yuav xaiv qhov kev xaiv PTFE, vim tias cov hluav taws xob hluav taws xob tsim los ntawm cov roj ntws yuav ua rau arc / hlawv thiab ua rau tus nqi, uas yuav ua rau hluav taws kub.
PTFE yog qhov nyuaj rau kev sib sau ua ke, tab sis nws lub neej tsis yooj yim cuam tshuam los ntawm qhov kub thiab txias.Qhov no ua rau nws yog ib qho kev xaiv zoo heev rau corrosive fuels, nrog rau lub hwj chim steering kab, turbine roj kab, thiab lwm yam. Vim li no, nws kuj yog ib qho kev xaiv zoo rau E85 thiab ethanol fuels thiab methanol.
