Hom kev railway accessories

Tsheb ciav hlau yog ib qho tseem ceeb heev ntawm kev thauj mus los. Ntau tus neeg tau pom thiab caij tsheb ciav hlau thiab tsheb ciav hlau, tab sis paub me ntsis txog kev tsheb ciav hlau. Qhov tseeb, railways yog tsim los ntawm ntau yam khoom siv thiab khoom siv. Raws li txoj kev tsheb ciav hlau vam meej, yog li ua cov railway accessories thiab khoom siv. Txhawm rau ua kom muaj kev nyab xeeb ntawm cov tsheb ciav hlau, cov khoom siv hluav taws xob tam sim no thiab cov khoom siv yuav tsum muaj zog dua, zoo dua toughness thiab zoo dua qaug zog. Hom kev tsheb ciav hlau muaj dab tsi?

1. Cov khoom sib txuas. Txij li cov kev tsheb ciav hlau tau tsim los ntawm ntau yam khoom siv thiab yog cov khoom sib xyaw ua ke, ntau yam txuas yuav tsum tau siv. Ib feem uas txuas ob qhov kawg ntawm ob txoj hlua yog hu ua kev sib koom ua ke. Ib feem uas txuas cov tsheb ciav hlau thiab cov neeg pw tsaug zog hu ua intermediate joint, uas yog qhov peb hu ua fastener. Cov pob qij txha tso cai rau lub log kom du du ntawm cov pob qij txha ntawm kev tsheb nqaj hlau thiab tso cai rau cov tsheb ciav hlau pem hauv ntej thiab nram qab ua haujlwm sib haum xeeb. Cov fasteners tuaj yeem ua ke nrog cov ntsia hlau thiab cov neeg pw tsaug zog los tsim ib txoj kab tsheb ciav hlau, tso cai rau ob txoj hlua kom tswj tau qhov tseeb ntawm tus txheeb ze; cov fasteners muab lub siab txaus los tiv thaiv txoj kev tsheb ciav hlau los ntawm kev sib tsoo thiab tiv thaiv kev tsheb ciav hlau los ntawm kev txav mus ntev.

2. Subgrade feem ntau yog hais txog lub ballast (ballast) cushion txheej nyob rau hauv lub binding thiab nyob rau saum npoo ntawm subgrade. Nws lub luag haujlwm tseem ceeb yog txhawb nqa cov neeg pw tsaug zog thiab faib cov khoom loj rau ntawm qhov siab ntawm cov neeg pw tsaug zog mus rau qhov chaw tsis sib xws, yog li txo qis deformation ntawm subgrade. Lub ballast yog ib qho me me ntawm granite nrog txoj kab uas hla ntawm 20 ~ 70mm. Muaj qhov sib txawv thiab kev sib txhuam ntawm cov blocks, tso cai rau kev khiav kom zoo elasticity. Thaum lub ballast poob elasticity, lub load ntawm lub pob zeb reinforced pw tsaug zog yuav nce ho piv nrog lub xeev ib txwm.

3. Turnouts yog kab txuas cov cuab yeej uas hloov tsheb ntawm ib txoj kev mus rau lwm qhov. Lawv feem ntau yog teem rau ntawm ntau qhov chaw nres tsheb thiab marshalling yards. Nws yog qhov tseeb vim yog cov keyboards uas lub peev xwm thauj mus los ntawm txoj kab tsheb ciav hlau no tuaj yeem siv tau tag nrho.
