1. Dab tsi ua rau rail taub hau deformation?
Rail taub hau deformation tshwm sim vim rov qab lub log sib cuag siab tshaj cov khoom siv lub zog tawm los. Hnyav qag loads thiab siab tsheb ciav hlau zaus ceev cov txheej txheem no. Hom deformation muaj xws li flattening, sab hnav, thiab yas ntws. Kev sib tsoo tsis tu ncua tuaj yeem rov qab tau qhov profile thiab txuas ntxiv kev tsheb nqaj hlau. Kev deformation hnyav yuav tsum tau hloov tam sim los tiv thaiv derailments.
2. Yuav tiv thaiv li cas los ntawm xob laim?
Kev tiv thaiv xob laim siv tooj liab txuas txuas txuas txuas rau cov pas nrig hauv av. Hauv cov cheeb tsam uas muaj hluav taws xob, cov ntawv cog lus impedance pab cuam tshuam cov hluav taws xob tam sim no thaum tswj cov teeb liab txuas ntxiv. Cov ntu tseem ceeb xws li qhov tunnels tau txhim kho kev tiv thaiv nrog surge arresters. Kev cog lus hauv av kom zoo txo cov kab hluav taws xob ua haujlwm tsis zoo thaum muaj cua daj cua dub.
3. Dab tsi yog rail cant (inclination) thiab vim li cas nws thiaj siv?
Rail cant yog hais txog sab hauv qaij (feem ntau 1: 40 gradient) uas sib tw log lub khob hliav qab. Qhov kev tsim no txhim kho lub log-rail contact geometry, txo flange hnav thiab dov tsis kam. Ntawm qhov nkhaus, cant pab faib cov khoom sib npaug ntawm sab hauv / sab nrauv. Kev tsis raug cai ua rau tsis sib xws hnav thiab suab nrov.
4. Qhov kub thiab txias cuam tshuam li cas rau cov ntsia hlau?
Nyob rau hauv huab cua kub, rails yuav buckle yog hais tias compressive kev nyuaj siab tshaj qhov txwv. Cov kub txias ua rau muaj kev ntxhov siab tensile, pheej hmoo tawg. Kev soj ntsuam cov kab ke taug qab kev tsheb ciav hlau kub los tswj kev txwv ceev thaum xav tau. Kev ntxhov siab- qhov ntsuas kub tsis pub dawb yog ntsuas thaum lub sijhawm teeb tsa rau cov huab cua hauv zos.
5. Dab tsi yog cov khoom siv hluav taws xob insulated siv rau?
Insulated pob qij txha hluav taws xob cais cov kab khiav mus rau cov khoom siv hluav taws xob zoo li thaiv cov kab hluav taws xob. Lawv siv cov khoom siv tsis yog -cov khoom siv hluav taws xob nruab nrab ntawm cov tsheb ciav hlau xaus thaum tuav lub zog txhua yam. Kev sib khi kom zoo tiv thaiv cov dej noo ingress uas tuaj yeem ua rau lub teeb liab tsis ua haujlwm. High- thaj chaw cuam tshuam yuav tsum muaj kev tsim kho ntxiv.
