Nta ntawm polyurethane ncua kev kawm ntawv rau tsheb
Txheem
Qhov xav tau kev hloov pauv yog qhia los ntawm squeaking thaum tsav tsheb. Thaum yuav cov khoom suav tsis zoo, qhov teeb meem feem ntau tshwm sim tom qab 2-3 lub hlis ntawm kev ua haujlwm.
Polyurethane tsheb ncua kev kawm ntawv yog ib qho txiaj ntsig zoo rau cov khoom siv roj hmab. Nws ua rau lub tsheb yooj yim los tswj cov huab cua phem thiab thaum tsav tsheb tawm ntawm txoj kev thiab hnav-tiv taus.
Dab tsi yog polyurethane suspension
Tsis muaj pendants ua tag nrho ntawm polyurethane (ib qho hluavtaws elastomer nrog cov cuab yeej programmable). Lub stabilizer bushing thiab ntsiag to block yog tsim los ntawm cov khoom siv no. Lub tom kawg yog qhov txuas txuas rau lwm qhov chassis thiab softens shocks thiab vibrations thaum tsav tsheb ntawm txoj kev bumpy.
Cov khoom siv polyurethane yog qhov zoo tshaj plaws rau kev tsav tsheb ntawm qhov chaw tsis zoo, kev tawm ntawm txoj kev, nruj overtaking thiab tas li ntse tig. Xws li cov qauv tsim feem ntau yog ntsia rau hauv cov xwm txheej hauv qab no:
- txhim kho cov tsheb ua kis las uas nws cov neeg tsav tsheb tig nrawm thiab sib kis ntawm txoj kev;
- txhim kho tsheb tuav rau cov neeg uas nyiam tsav tsheb nruj;
- kev kho dua ntawm kev txo nqi ntawm cov tsheb ntawm cov qauv qub, uas tau deteriorated vim siv ntev.
Polyurethane tsis muaj xim, tab sis xim daj, dub, txiv kab ntxwv, liab, thiab xiav yog muag. Cov neeg tsim khoom tshwj xeeb sib xyaw xim los qhia qhov nyuaj.
Cov xwm txheej rau kev pabcuam ntev
Polyurethane qhov chaw yuav ua haujlwm tsawg kawg yog 50-100 txhiab km nyob rau hauv cov xwm txheej ib txwm muaj thiab 25-50 txhiab km thaum tsav tsheb tawm ntawm txoj kev thiab hauv kev tsav tsheb hnyav, yog tias muaj ntau yam xwm txheej:
- tsheb ncua kev kawm tag nrho;
- Cov blocks uas ntsiag to raug ntsia kom raug;
- stabilizer kev txhawb nqa yog kho nrog cov roj tsis muaj dej;
- Kev ua haujlwm yog nqa tawm ntawm qhov kub tsis qis dua -40 ° C.
Priora muffler ncua kev kawm ntawv
Thiab qhov tseem ceeb tshaj plaws, cov khoom yuav tsum yog tshiab thiab los ntawm cov chaw tsim khoom ntseeg siab.
Pros thiab Cons
Polyurethane qhov chaw muaj qhov zoo hauv qab no:
- Lawv yog characterized los ntawm siab hnav tsis kam. Cov khoom lag luam zoo ua los ntawm polyurethane kav ntev dua li cov khoom ua los ntawm cov roj hmab muag muag.
- Ua kom lub suspension ntau elastic. Lub tsheb yooj yim dua rau kev tsav tsheb hauv txoj kev tsis zoo thiab huab cua (dej, daus, cua daj cua dub).
- Lawv zam cov teebmeem ntawm cov tshuaj reagents, uas yog abundantly sprinkled rau txoj kev nyob rau hauv lub caij ntuj no. Roj hmab deteriorates sai dua thaum de-icing sib tov lo.
- Txhim kho tsheb tswj. Vim muaj cov txheej txheem polyurethane hauv kev ncua, nws yooj yim dua rau tus neeg tsav tsheb tswj lub tsheb. Tswj kom kaum zoo ntawm kev kub ceev thiab hla lwm tus yooj yim dua.
- Lawv hnav tawm qeeb dua piv rau cov khoom siv roj hmab muag.
- Haum rau siv nyob rau hauv huab cua hnyav. Polyurethane, tsis zoo li roj hmab, tsis tawg thaum txias thiab tsis qhuav tawm thaum lub caij ntuj sov.
Tab sis qhov tsis zoo tsis muaj tsawg dua qhov zoo:
- Cov tuam txhab tsheb tsis nruab qhov chaw polyurethane, yog li koj yuav tsis tuaj yeem yuav cov khoom qub. Muaj kev pheej hmoo loj ntawm kev khiav mus rau qhov tsis zoo uas tsis zoo.
- Lub ncua kev kawm ntawv yuav elastic heev, yog li thaum tsav tsheb ntawm txoj kev tsis sib xws, tus neeg tsav tsheb yuav hnov txog txhua lub pob.
- Polyurethane qhov chaw tuaj yeem tawg thaum txias txias (hauv qab -40 ° C). Cov khoom tsis zoo tuaj yeem tiv taus -20 ° C.
- Lawv kim dua li cov qauv roj hmab qub (tab sis tsis ua haujlwm qis dua).
- Polyurethane muaj qhov tsis zoo ntawm cov hlau stabilizers, yog li lawv yuav tsum tau hloov ntau zaus.
Tsis tas li ntawd, polyurethane tsis ua raws li cov hlau zoo thiab tuaj yeem tev tawm ntawm nws. Feem ntau, nws yog vim li no tias cov blocks uas ntsiag to tshiab yuav tsum tau teeb tsa.
Qhov xav tau kev hloov pauv yog qhia los ntawm squeaking thaum tsav tsheb. Thaum yuav cov khoom suav tsis zoo, qhov teeb meem feem ntau tshwm sim tom qab 2-3 lub hlis ntawm kev ua haujlwm.
Kev teeb tsa ntawm polyurethane bushings thiab cov blocks uas ntsiag to yog tsim nyog yog tias kev txhim kho lub tsheb tuav, tsis yog kev nplij siab ntawm tus neeg tsav tsheb thiab cov neeg caij tsheb, los ua ntej.
Yuav ua li cas xaiv ib feem
Thaum xaiv polyurethane qhov chaw rau tsheb ncua kev kawm ntawv, ua raws li cov cai hauv qab no:
- Yuav cov qauv tsim los ntawm cov tuam txhab tsim khoom zoo. Lawv yog cov zoo, txawm hais tias lawv yog kim tshaj li Suav versions.
- Tsis txhob cuam tshuam nrog cov neeg muag khoom uas muab cov khoom siv.
- Xaiv ib feem hauv lub khw kom koj tuaj yeem tshawb xyuas nws kom tawg, khawb lossis lwm yam kev puas tsuaj.
- Tsis txhob yuav los ntawm qhov chaw nrog kev tshaj tawm.
- Lub kaw lus ntsiag to yuav tsum tau muag hauv cov ntim khoom ruaj khov nrog daim ntawv lo qhia lub npe ntawm ntu, chaw nyob thiab xov tooj ntawm cov chaw tsim khoom, e-mail lossis lwm cov ntaub ntawv tiv tauj, thiab ua raws li GOST cov qauv.
- Yuav tsuas yog cov blocks ntsiag to uas cov chaw tsim khoom muab kev tiv thaiv (feem ntau 1-2 xyoos, tsis hais txog mais).
Nco ntsoov saib daim ntawv pov thawj ntawm kev sib haum xeeb. Yog tias tus neeg muag khoom tsis kam muab cov ntaub ntawv los tshuaj xyuas, qhov no yog qhov cuav.
Yuav ua li cas rau nruab polyurethane hangers
Koj yuav tsis tuaj yeem nruab polyurethane qhov chaw koj tus kheej. Txhawm rau ua qhov no, koj xav tau ib chav nrog kev hla dhau, qhov av lossis nqa thiab cov cuab yeej tshwj xeeb kom tshem tawm qhov kev ncua. Tso cov haujlwm rau cov kws tshaj lij los ntawm lub chaw pabcuam tsheb.
