Dab tsi yog qhov txawv ntawm rail pads thiab rail insulators?
Rail padsFeem ntau muab cushioning thiab vibration dampening, feem ntau ntsuas 5-10mm tuab.Rail insulatorsyog thicker (10-20mm) thiab ua hauj lwm ntxiv ntawm hluav taws xob rwb thaiv tsev, tiv thaiv tam sim no to hauv hluav taws xob rail systems thiab tiv thaiv signaling circuits los ntawm kev cuam tshuam.
Railway Pad
Rail pads yog elastic polyurethane mats uas yog interposed ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum los ntawm hnav thiab cuam tshuam.
Lub rail pad nteg nyob rau hauv lub tsheb ciav hlau yog siv los lav:
- Lub load faib npog thaj tsam loj dua
- Txo cov load concentration thiab kev siv qaug zog kev nyuaj siab
- Txawm thaj chaw sib cuag ntawm txoj kev tsheb ciav hlau thiab cov khoom txhawb nqa
- Txo cov suab nrov thiab cov qauv kev co
- Sealing muaj nuj nqi ntawm kev txhawb nqa sab saum toj thiab kev tsheb nqaj hlau hauv qab
- Txo cov tsheb ciav hlau hnav thiab cov khoom txhawb nqa muaj feem cuam tshuam

Railway insulator
Rail insulator, tseem hu ua railroad insulator, rail rwb thaiv tsev, rail nylon insulator, nws yog ntsia nruab nrab ntawm steel rail thiab khi phaj, rau kho rail gauge thiab hluav taws xob insulating railroad rails, rail clips thiab rail bolts los ntawm sab hauv ntawm ib tug pob zeb pw tsaug zog. Nws txoj haujlwm yog tib yam li lub tsheb ciav hlau, tab sis nws yog tuab dua li lub tsheb ciav hlau. Rau kev kub ceev lossis siab load tsheb ciav hlau, nws yog ib qho tsim nyog rail fastener .
Cov insulators siv rau rails xws li60kg (UIC) rail, 52kg rail, 136RE Rail, 90R, 75R, 50R, 60Rthiab lwm yam rail insulator yog tsim los ntawm kev txhaj tshuaj molding ntau lawm, thiab nws yog tsim los ntawm Nylon-6 los yog Nylon-66 nrog iav muab cov ntsiab lus 20% mus rau 35% nyob ntawm qhov specification. Cov khoom no yog UV stabilized thiab muaj nyob rau hauv ntuj xim los yog raws li ib tug yuav tsum tau.
Cov khoom ntawm peb cov rail insulators yog raws li nram no:
