Yog vim li cas rail ntses daim hlau siv nyob rau hauv railways?
Rail ntses daim hlau (los yog splice tuav) yog cov khoom tseem ceeb hauv kev tsheb ciav hlau siv los koom nrog ob txoj kev tsheb ciav hlau xaus. Lawv tuav txoj kab rov tav thiab ntsug, ua kom muaj kev ncaj ncees los ntawm kev faib cov log tsheb, thiab tso cai rau thermal expansion / contraction, yog li txhim kho kev nyab xeeb, ruaj khov, thiab txo kev txij nkawm.
- Txuas Rails:Lawv tuav cov tsheb ciav hlau uas nyob ib sab ua ke, ua kom muaj kev txuas ntxiv ntawm txoj kev taug.
- Load Distribution:Lawv ua raws li tus choj, hloov lub log loads ntawm ib lub tsheb ciav hlau mus rau lwm qhov, uas txo cov kev ntxhov siab ntawm kev sib koom ua ke.
- Alignment thiab Stability:Lawv tuav cov theem kom zoo (ntu) thiab kab (kab rov tav) ntawm txoj kev tsheb ciav hlau, tiv thaiv deflection lossis kev sib koom ua ke hauv kev sib tw hnyav.
- Expansion Allowance:Tsim los nrog cov qhov slotted, lawv tso cai rau kev nthuav dav thiab kev cog lus thaum lub sij hawm hloov pauv kub, tiv thaiv kev khiav buckling.
- Kev nyab xeeb thiab kev saib xyuas:Los ntawm kev ntxiv dag zog rau kev sib koom ua ke, lawv tiv thaiv derailments thiab txo qhov xav tau ntawm kev saib xyuas tsis tu ncua.
- Kev them nyiaj yug Signaling:Tshwj xeeb tsim insulated ntses daim hlau yog siv los tsim hluav taws xob kev sib cais ntawm rail seem rau niaj hnub signaling systems.
Yuav Siv Daim Npav Ntses Ntau npaum li cas thiaj kuaj tau?
Rail ntses daim hlau (cov tuav sib koom ua ke) yuav tsum tau tshuaj xyuas txij li ib lub lim tiam rau siab - cov kab tsheb loj (50+ tsheb ciav hlau / hnub) mus rau txhua 3-6 lub hlis rau kev tsheb nruab nrab, thiab tsawg kawg ib xyoos rau kev khiav qis qis. Kev tshuaj xyuas yog tsom rau kev kuaj xyuas lub bolts nruj, nrhiav kev tawg, saib xyuas kev hnav, thiab ua kom muaj kev sib tw tsheb ciav hlau kom raug.
Kev tshuaj xyuas thiab kev saib xyuas cov ntsiab lus tseem ceeb:
Ntau zaus:High - thaj chaw tsheb yuav tsum tau tshuaj xyuas txhua 3-6 lub hlis (lossis txhua lub limtiam rau cov tsheb thauj neeg hnyav heev) txhawm rau kuaj xyuas lub bolt loosening thiab rail kawg batter.
Yuav kuaj li cas:
- Tightness: Kos ntsia liaj qhov rooj torque (feem ntau 400-600 Nm) kom tsis txhob xoob pob qij txha.
- Cracks / Hnav: Saib xyuas qhov qaug zog tawg, tshwj xeeb tshaj yog nyob ib ncig ntawm lub qhov taub.
- Corrosion: Tshawb xyuas cov xeb, uas tuaj yeem ua rau kev sib txuas tsis muaj zog.
- Kev Ntsuas Ua Tau: Hloov cov phaj ntses puas lossis tawg tam sim ntawd. Tsis tu ncua lubrication ntawm bolt threads tuaj yeem tiv thaiv corrosion.
- Siab -Qhov Ntsuas Qhov Ntsuas: Yog tias qhov sib txawv ntawm txoj hlua loj dhau los lossis yog tias qhov sib koom ua ke pom qhov kev sib hloov ntsug ntau dhau, yuav tsum tau saib xyuas tam sim ntawd.
