Dab tsi yog hom kev tsheb ciav hlau?
Arail ncooyog muab tso rau hauv nruab nrab ntawm lub tsheb ciav hlau thiab baseplate los yog sleeper. Rail ncoo yog qhia rau txoj kev tsheb ciav hlau fastening system vim nws cov resilience los yog viscoelasticity uas yuav siv tau nyob rau hauv kev cuam tshuam ntawm qaug zog tawg ntawm pw tsaug zog. Lub dynamic kev ntxhov siab los ntawm lub log los yog kev tsheb nqaj hlau cuam tshuam los ntawm ob qho tib si tsis tu ncua thiab tsis xwm yeem txav yog attenuated. Muaj qhov txiaj ntsig ntxiv ntawm kev txo cov kev saib xyuas thiab cov nqi cuam tshuam.
Rail pads yog categorized los ntawm cov khoom (Rubber, EVA, HDPE, Composite) thiab tsim (Grooved, Studded, Nruam, Discontinuous), ua hauj lwm rau cushion impacts, txo kev co, thiab nce kev sib txhuam ntawm rails thiab sleepers rau txawv railway xav tau kev pab, los ntawm siab - ceev mus rau crane lem.
Los ntawm Khoom

- Composite Pads:Ua los ntawm cov khoom siv zoo li fiberglass lossis polyurethane rau lub zog thiab lub teeb.
Los ntawm Tsim / Hom
- Grooved Pads:Feature grooves kom haum cov tsheb ciav hlau / pw tsaug zog interfaces, muab kev ruaj ntseg zoo dua.
- Studded Pads:Tau tsa studs rau txhim kho tuav thiab vibration damping, zoo rau ib puag ncig nyuaj.
- Nruam Pads:Npog tag nrho cov pw tsaug zog, siv rau kev txhawb nqa txuas ntxiv.
- Discontinuous Pads (Sole Phaj):Siv rau kev txhawb nqa tsis tu ncua, xws li ntawm cov txuas hniav lossis hom kev hloov pauv tshwj xeeb.
Cov Variations
- Elastomer Pads:Lub sij hawm dav dav rau roj hmab / polymer ncoo rau kev poob siab.
- Cork Rubber Pads:Siv ua cushions, txawm tias roj hmab feem ntau ua haujlwm zoo dua lawv.
GNEE RAILmuaj 16 pawg ntawm Engel txhaj tshuab (2 teev ntawm 350T, 2 teev ntawm 450T, 5 teev ntawm 650T, 3 teev ntawm 850T, 4 teev ntawm 1350T) thiab 1 cov tshuab ziab khaub ncaws siab heev, tshwj xeeb hauv kev tsim cov tsheb ciav hlau, tsheb, thiab lwm yam khoom siv yas. Tam sim no, lub peev xwm ntau lawm ntawm high{13}}ceev rail accessories yog raws li nram no: 90,000 Pcs / hli rau gauge phaj, 900,000 Pcs / hli rau nylon dowels, 450,000 Pcs / hli rau rail pads, 90,000 Pcs / hli rau qhov siab 2, 1,200,000 Pcs / hli rau insulating pads, thiab lwm yam.
Peb EVA / HDPE / roj hmab rail pads yog nrog siab elasticity, siv rau cov hom kev tsheb ciav hlau xws li rail UIC54, UIC60, BS80lbs, BS100lbs, thiab ntau thiab tsawg raws li tau txiav txim. Cov ntaub qhwv tuaj yeem kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
