Dab tsi Txhua Cheeb Tsam Ua
Lub tsheb ciav hlau khi phaj, tseem hu ua lub hauv paus phaj, yog ib lub phaj steel uas muab tso rau hauv qab ntawm txoj kev tsheb ciav hlau thiab nyob rau sab saum toj ntawm tus neeg pw tsaug zog. Nws txoj hauj lwm yog cov txheej txheem: nws kis tau lub log load nyob rau hauv ib tug loj chav pw cheeb tsam, nres txoj kev tsheb ciav hlau los ntawm kev txiav mus rau hauv lub cav ntoo los yog pob zeb, tuav lub tsheb ciav hlau ntawm qhov tseeb gauge los ntawm nws lub xub pwg nyom los yog qhov, thiab muab ib tug ca, ruaj khov bearing nto rau txoj kev tsheb ciav hlau ko taw.
Lub tsheb ciav hlau pad yog ib qho khoom siv elastic, feem ntau yog roj hmab, EVA, TPEE lossis HDPE, cuam tshuam ntawm txoj kev tsheb ciav hlau thiab cov hlua khi, los yog ncaj qha ntawm txoj kev tsheb ciav hlau thiab cov pw tsaug zog ntawm cov tshuab tsis muaj phaj. Nws txoj hauj lwm yog dynamic: nws absorbs cuam tshuam, damps vibration, txo suab nrov, faib lub load tusyees thiab tiv thaiv lub sleeper saum los ntawm puas thiab qaug zog tawg. Ntawm cov kab hluav taws xob lub ncoo kuj muab hluav taws xob rwb thaiv tsev ntawm kev tsheb ciav hlau thiab pw tsaug zog.

Vim Li Cas Ib Leeg Thiaj Hloov Tsis Tau Lwm Tus
Lub khi phaj tsis tuaj yeem hloov lub ncoo tag nrho vim tias ob lub ntsiab lus teb cov kev xav tau sib txawv. Tshem tawm lub ncoo tawm ntawm txoj kev tsheb ciav hlau so ncaj qha ntawm cov hlau lossis ntawm lub txaj pw los ntawm lub phaj; cuam tshuam lub zog ces taug kev ncaj nraim mus rau hauv lub sleeper thiab ballast, accelerating pob zeb sleeper cracking, nce suab nrov, thiab tshem tawm cov hluav taws xob rwb thaiv tsev lub signaling Circuit Court nyob ntawm. Tshem tawm lub phaj tawm ntawm lub ncoo ib leeg kom nqa lub log hnyav hnyav; cov ntaub ntawv elastic ces raug mob ntxov ntxov crushing thiab lub ntsuas yuav tsis zoo txwv. Fastening systems khaws ob qho tib si, thiab ob qho tib si sib xyaw ua ke: lub phaj rau qhov nruj thiab ntsuas, lub ncoo rau qhov tseeb dynamic nruj nyob rau hauv lub qag load thiab ceev ntawm txoj kab.
Kev taw qhia kev xaiv rau cov neeg yuav khoom
Sib piv cov qauv ncoo rau txoj kev tsheb ciav hlau thiab hom pw tsaug zog: piv txwv li 60-10-17 rau 60 kg / m rail nrog 10 mm thickness thiab 17 mm dav tsis, raws li qhov kev teeb tsa fastening.
Xaiv cov ntaub qhwv ntaub los ntawm kev nyab xeeb thiab lub luag haujlwm: EVA thiab HDPE rau qhov chaw ruaj khov, qhuav; cov roj hmab ntuj lossis TPEE qhov twg tsawg -kub elasticity yuav tsum tau.
Tshawb xyuas qhov kev khiav hauj lwm qhov kub thiab txias tiv thaiv kab qhov chaw; -50℃txog 70℃npog feem ntau cov kev qhia tshwj xeeb, tab sis cov phiaj xwm arctic xav tau cov khoom sib xyaw ua ke txias.
Txheeb xyuas cov hlua khi lub xub pwg qhov siab thiab lub qhov qauv tiv thaiv lub ncoo hneev taw kom lub ncoo tsis pinched lossis sab laug tsis txhawb nqa ntawm ntug.
Khaws cov ntaub qhwv rau hauv qhov chaw huv, qhov cua kom deb ntawm tshav ntuj ncaj qha, qhov chaw tshav kub, roj, cov kuab tshuaj thiab cov tshuaj reagents; raug degrades lub elastomer ua ntej installation.
Kev Ntseeg Tsis Zoo
Ib qho kev xav ntau tshaj plaws yog tias khi phaj tsuas yog qhov muaj zog dua ntawm cov ntaub qhwv, yog li lub ncoo tuaj yeem hla ntawm txoj kev hnyav. Nyob rau hauv kev xyaum hnyav axle loads nce, tsis txo, qhov xav tau rau elastic txaj, thiab hla lub ncoo ua rau pw tsaug zog sab saum toj kev puas tsuaj thiab ntau dua tu. Lwm qhov kev xav tsis zoo yog tias lub ncoo hardness ib leeg txhais tau hais tias kev ua tau zoo; lub ncoo qhov zoo li qub thiab dynamic tawv, thickness thiab rwb thaiv tsev kuj tau teev ua ke. Thaum kawg, cov ntaub qhwv tau qee zaum ntseeg tau tias yuav hloov tau thoob plaws kev tsheb ciav hlau; Qhov tseeb, ib lub ncoo sib phim rau 50 kg / m rail zaum tsis raug raws li 60 kg / m rail thiab hloov cov ntiv taw zoo ntawm qhov clip.
Cov lus nug nquag
Q: Puas tuaj yeem siv txoj hlua khi hlua khi los ntawm kev sib tsoo roj hmab?A: Tsis yog. Lub khi phaj muab cov qauv kev txhawb nqa thiab ntsuas thaum lub ncoo muab elasticity, poob siab thiab rwb thaiv tsev. Siv tsuas yog ib qho ntawm ob txoj kev taug kev tsis muaj kev nruj lossis cushioning, nce hnav, suab nrov thiab pw tsaug zog puas tsuaj.
Q: Kuv puas xav tau ib lub tsheb ciav hlau yog tias kuv twb siv lub khi phaj?A: Yog, ntawm cov pob zeb pw tsaug zog thiab ntawm cov phaj steel feem ntau. Lub ncoo zaum ntawm lub tsheb ciav hlau ko taw thiab lub phaj, tiv thaiv tus neeg pw tsaug zog thiab insulating lub tsheb ciav hlau los ntawm lub phaj thiab pw tsaug zog.
Q: Dab tsi yog cov ntaub ntawv zoo tshaj plaws?A: Nws nyob ntawm txoj kab: cov roj hmab ntuj muaj qhov zoo tshaj plaws qis - kub elasticity, EVA qhov zoo tshaj plaws huab cua ruaj khov, TPEE lub neej qaug zog zoo tshaj plaws, thiab HDPE qhov zoo tshaj plaws rigidity. Specification yog tsav los ntawm fastening system tsim, tsis yog los ntawm cov khoom nyiam ib leeg.
Q: Yuav ua li cas tuab yuav tsum tau rail pad?A: Feem ntau qhov tseem ceeb yog 6-7 hli rau cov kab qauv, 9-12 hli rau kev pabcuam siab ceev thiab hnyav, thiab txog li 20 hli rau kev thauj khoom hnyav; thickness yog teem los ntawm fastening system daim duab thiab los ntawm qhov yuav tsum tau muaj zog static.
Q: Yuav ua li cas rail pads yuav khaws cia ua ntej installation?A: Nyob rau hauv qhov chaw huv, qhov cua, npog qhov chaw deb ntawm lub hnub ncaj qha, tshav kub, roj thiab tshuaj lom neeg; feem ntau elastomers degrade nyob rau hauv UV thiab cov roj tiv tauj txawm tias ua ntej lawv nkag mus rau kev pabcuam.
