1. Lub neej ntev ntawm kev sib koom ua ke yog dab tsi?
Bolted pob qij txha kav 5-10 xyoo nrog kev saib xyuas kom raug. Welded pob qij txha tuaj yeem kav ntev dua 20 xyoo yog tias teeb tsa kom raug. Insulated pob qij txha yuav tsum tau hloov txhua 8-15 xyoo. Lifespan nyob ntawm qhov ntim tsheb thiab ib puag ncig. Kev tshuaj xyuas tsis tu ncua pab ua kom lub neej ntev.
2. Cov kev tsheb ciav hlau ua haujlwm li cas thiaj li muaj kev nyab xeeb ntawm kev tsheb ciav hlau?
Kev ruaj ntseg pob qij txha tiv thaiv kev sib cais thiab derailments. Kev sib raug zoo kom txo tau hnav ntawm lub tsheb ciav hlau log. Insulated pob qij txha kom paub meej qhov tseeb. Zoo- khaws cov pob qij txha txo qhov kev pheej hmoo ntawm kev sib tsoo. Cov txheej txheem kev nyab xeeb nyob ib puag ncig cov pob qij txha tiv thaiv cov neeg ua haujlwm thiab cov neeg caij tsheb.
3. Dab tsi yog qhov sib txawv ntawm kev sib koom ua ke ntawm cov tsheb ciav hlau thiab cov tsheb ciav hlau fastenings?
Rail pob qij txha txuas cov tsheb ciav hlau xaus, thaum fastenings ruaj ntseg rau cov neeg pw tsaug zog. Cov pob qij txha tuav longitudinal rog; fastenings tuav ntsug thiab lateral zog. Ob qho tib si tseem ceeb rau kev taug kev ruaj ntseg. Cov pob qij txha tau pom ntau dua thiab yuav tsum tau kuaj xyuas ntau zaus. Fastenings yog yooj yim dua tab sis tseem ceeb sib npaug.
4. Yuav ua li cas cov tsheb ciav hlau sib koom ua ke kom haum rau kev nthuav dav?
Kev nthuav dav qhov sib txawv yog sab laug nyob rau hauv bolted pob qij txha rau thermal txav. Welded pob qij txha siv cov cuab yeej nthuav dav hauv huab cua huab cua. Kev sib koom ua ke yuav tsum sib npaug qhov yooj thiab ruaj khov. Engineers xam qhov sib txawv qhov ntau thiab tsawg raws li qhov kub thiab txias. Qhov tsis raug cai tuaj yeem ua rau taug qab buckling.
5. Dab tsi yog cov cim qhia ntawm kev sib koom ua tsis tiav?
Pom kab nrib pleb los yog deformation nyob rau hauv fishplates qhia tsis ua hauj lwm. Loos los yog ploj lawm bolts yog tus chij liab. Cov suab nrov txawv txawv thaum tsheb ciav hlau hla qhia txog kev sib koom ua ke. Cov kev sib tw tsis zoo nyob ze cov pob qij txha yuav tsum tau saib xyuas tam sim ntawd. Kev saib xyuas tsis tu ncua pab tshawb xyuas earl
