hlau rail
Raws li ib qho tseem ceeb ntawm cov qauv kev tsheb ciav hlau, steel rail yog siv los coj lub tsheb ciav hlau log mus rau pem hauv ntej. Txoj haujlwm ntawm kev tsheb ciav hlau yog los tiv thaiv lub zog loj ntawm lub log, thiab dhau mus rau cov neeg pw tsaug zog. Steel rail yuav tsum muab nruam, du nto ntawm qhov tsawg kawg nkaus tiv thaiv lub tsheb ciav hlau log. Cov tsheb ciav hlau niaj hnub siv sijhawm ntau xyoo los txhim kho cov khoom zoo, piv txwv li, cov khoom siv ntawm steel rail tau hloov mus rau hauv cov hlau los ntawm cov hlau. Steel rail yog feem ntau ua rau hauv I-beam, thiab nws yog ua los ntawm high- zoo steel alloy. Lub zog ntawm cov tsheb ciav hlau thiab lwm qhov chaw khiav tsheb yog qhov tseem ceeb rau lub tsheb ciav hlau kom ceev thiab nyab xeeb.
Hom kev tsheb ciav hlau
Raws li kev sib txawv xws li qhov hnyav, tus qauv, lub zog tensile, steel rail yuav muab faib ua ntau hom. Coj lub teb chaws tus qauv ua piv txwv, peb tuaj yeem faib cov kev tsheb ciav hlau Steel rau hauv hom hauv qab no.

Suav standard steel rail
Los ntawm qhov hnyav ib 'meter', Suav tus qauv steel rail yuav muab faib ua peb hom, xws li hnyav rail, lub teeb rail thiab crane rail. Thaum qhov hnyav ib meter ntawm steel rail yog sib npaug los yog tsawg dua 30kg, nws yog hu ua lub teeb rail. Ntawm qhov tsis sib xws, kev tsheb ciav hlau hnyav yog xa mus rau qhov hnyav ib meter ntawm kev tsheb nqaj hlau yog ntau tshaj 30kg.

Technical Reasoning Tom qab xaiv
Hauv kev lag luam thiab kev siv mining, kev thauj khoom feem ntau yog nruab nrab tab sis rov ua dua, uas tuaj yeem ua rau qaug zog hauv cov hlua sib dua. Lub 24kg profile muab lub taub hau kev tsheb ciav hlau muaj zog dua thiab lub hauv paus kev txhawb nqa thaum tseem yooj yim dua los tuav thiab nruab. Qhov kev sib xyaw no txhawb kev ua haujlwm ruaj khov yam tsis muaj kev siv nyiaj ntau.
Cov txiaj ntsig kev ua haujlwm
Xaiv ib txoj kev tsheb ciav hlau uas phim cov kev ua haujlwm uas xav tau ua rau:
- Tsawg tus nqi pib yuav khoom
- Txo lub sijhawm ua haujlwm ntawm kev teeb tsa
- Lub sijhawm ua haujlwm ntev dua
- Cov nqi kho mob qis dua
Qhov no yog tshwj xeeb tshaj yog muaj feem xyuam thaum rails yuav tsum nyob rau hauv lub xyoo nyob rau hauv cyclical load tej yam kev mob.
