Rail Pads tiv thaiv Rail Sleepers li cas?
Rail padstiv thaiv cov neeg pw tsaug zog los ntawm kev faib cov khoom sib npaug, txo kev poob siab thiab kev co, thiab tiv thaiv kev hnav thiab qaug zog. Lawv yog cov khoom siv elastic, feem ntau yog ua los ntawm cov roj hmab lossis polyurethane, muab tso rau hauv nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog los ua qhov kev tiv thaiv tsis zoo tiv thaiv kev ntxhov siab ntawm kev hla tsheb ciav hlau.
Yuav ua li cas rail pads tiv thaiv sleepers?
- Load faib:Los ntawm kev tso ib lub ncoo ntawm txoj kev tsheb ciav hlau thiab tus neeg pw tsaug zog, qhov hnyav ntawm lub tsheb ciav hlau hla tau kis mus rau thaj tsam loj dua ntawm tus neeg pw tsaug zog. Qhov no tiv thaiv qhov siab - cov ntsiab lus siab thiab qhov siab ntawm cov khoom thauj, uas tuaj yeem ua rau puas tsuaj.
- Shock thiab vibration absorption:Cov khoom siv elastic ntawm lub tsheb ciav hlau pad absorbs thiab dampens qhov cuam tshuam thiab kev vibrations ntawm lub tsheb ciav hlau lub log. Qhov no txo cov kev ntxhov siab ntawm cov neeg pw tsaug zog, uas yog qhov tseem ceeb tshwj xeeb rau cov neeg pw tsaug zog uas cuam tshuam rau kev qaug zog tawg los ntawm kev cuam tshuam thiab kev vibrations.
- Hnav txo:Cov pads tiv thaiv qhov ncaj qha, abrasive kev sib cuag ntawm steel rail thiab sab saum toj ntawm lub sleeper. Qhov no tshem tawm cov abrasion thiab crushing ntawm lub sleeper nto.
- Kev tshem tawm kev ntxhov siab:Los ntawm kev tshem tawm cov load concentration thiab absorbing vibrations, rail pads kuj tshem tawm qhov ua rau qaug zog kev nyuaj siab ntawm tus neeg tsaug zog.
- Nto them nyiaj:Rail pads tuaj yeem nqus qhov tsis sib xws ntawm hauv qab ntawm txoj kev tsheb ciav hlau thiab sab saum toj ntawm tus neeg pw tsaug zog, ua kom muaj kev sib cuag ntau dua thiab txo kev ntxhov siab.
Railway pads ua haujlwm txoj cai
Lub hauv paus ntsiab lus ntawm railway pad ua hauj lwm feem ntau yog raws li cov ntaub ntawv railway pad ' elasticity thiab lawv cov qauv tsim:
- Thaum cov tsheb ciav hlau hla, railway pads yuav muaj elastic deformation. Hom deformation no tuaj yeem nqus cov tsheb ciav hlau 'dynamic load, thiab txo qhov ua rau muaj kev cuam tshuam nruj rau cov ntsia hlau thiab khi.
- Dab tsi ntxiv, cov ntaub ntawv ntawm kev tsheb ciav hlau, xws li roj hmab, EVA, lossis HDPE, txhua tus muaj peev xwm nqus tau thiab tawg lub zog. Thaum lub tsheb ciav hlau hu rau lub tsheb ciav hlau, lub tsheb ciav hlau pads nqus thiab tawg lub zog kom txo qis kev tsheb ciav hlau txoj kev tsheb ciav hlau qhov kev co thiab suab nrov.
- Tom qab lub tsheb ciav hlau hla, lub tsheb ciav hlau yuav rov qab los rau nws qhov qub thiab lub xeev. Uas ua kom lub railway ncoo lub durability thiab stability thaum siv ntev.
