Qhov tseem ceeb ntawm kev kiv cua txij nkawm
Kev tsheb nqaj hlau yog ib qho tseem ceeb tshaj plaws hauv kev ua haujlwm ntawm kev tsheb ciav hlau, uas yog cuam tshuam ncaj qha rau kev nyab xeeb thiab nrawm ntawm kev ua haujlwm tsheb ciav hlau. Yog li ntawd, kev tu sab kev txij nkawm yog qhov tseem ceeb tshaj plaws. Irrational lossis tsis muaj kev kho mob yuav ua rau muaj teeb meem xws li cov kab nrib pleb thiab deformation ntawm ntsia, thiab txawm ua rau muaj kev sib tw loj. Yog li, tsim cov kev tshawb fawb thiab tsim nyog kev tsheb ciav hlau yog qhov tsim nyog ntsuas yog qhov tsim nyog ntawm kev nyab xeeb thiab kev ua haujlwm ntawm kev ua haujlwm railway.
Yuav ua li cas los ua cov kev tshawb fawb thiab tsim nyog tu
1. Kev tshuaj xyuas ib txwm:
Thawj kauj ruam hauv kev tu tus kiv cua yog kev tshuaj xyuas ib txwm. Kev kuaj xyuas tau raws sijhawm ntau yam teeb meem ntawm cov ntsia, xws li cov kab nrib pleb, deformation, thiab nqa tawm kev saib xyuas hauv lub sijhawm.
2. Rail sib tsoo:
Cov ntsia yuav hnav tawm tom qab kev siv ntev ntev thiab yuav tsum tau ua av. Kev sib tsoo tuaj yeem ua kom ntseeg tau tias cov duab ntsuas ntev thiab zoo ntawm cov ciav hlau ua tau raws cov qauv kev nyab xeeb thiab kev ua haujlwm ntawm kev tsheb khiav kev lag luam.
3. Kev Rail Hloov:
Thaum tawg, deformation thiab lwm yam teeb meem tshwm sim hauv kev ntsia, lawv yuav tsum tau hloov. Hloov tuaj yeem zam kev nyab xeeb kev phom sij thaum siv cov kev sib tw thiab paub meej txog kev nyab xeeb thiab kev ua haujlwm ntawm kev ua haujlwm railway.
4. Kev kho mob corrosion:
Cov ntsia yuav tsum tau kho nrog kev tiv thaiv corrosion. Kev kho mob corrosion corrosion tuaj yeem tiv thaiv cov ntsia hlau los ntawm oxidized thiab corroded thiab corroded, yog li nthuav tawm lub neej ntawm kev ntsia.
5. Kev tu thiab txij nkawm:
Cov ntsia yuav tsum tau ntxuav thiab khaws cia. Kev ntxuav tu tuaj yeem tshem tawm cov impurities thiab av nyob rau saum npoo ntawm cov ntsia kom ntseeg tau tias qhov zoo ntawm cov kev cai ua tau raws cov qauv.
Hauv cov ntsiab lus, cov qauv tsim thiab kev siv ntawm kev saib xyuas kev tsheb yog qhov tsim nyog ntsuas kom ntseeg tau kev nyab xeeb thiab kev ua haujlwm ntawm kev khiav haujlwm. Thaum ua kev soj ntsuam kev sib tw, kev tshuaj xyuas kev sib tsoo, kev hloov tsheb ciav hlau, kev tu thiab kev tu kho kom ntseeg tau lub neej thiab kev nyab xeeb ntawm cov ntsia.
