1. Dab tsi yog cov khoom tseem ceeb ntawm tus qauv bolted rail sib koom ua ke?
Tus qauv bolted rail sib koom ua ke muaj ob lub phaj, plaub mus rau rau siab - lub zog bolts, lub caij nplooj ntoos hlav ntxhua khaub ncaws, thiab txiv ntoo. Cov ntses phaj yog tsim los kom phim cov kev tsheb ciav hlau profile zoo kawg nkaus rau kev pom kev thauj mus los. High- tensile bolts xyuas kom qhov kev sib txuas tseem ruaj ntseg nyob rau hauv dynamic loads. Lub caij nplooj ntoos hlav ntxhua khaub ncaws tuav tas li kom tsis txhob xoob ntawm kev vibrations. Tag nrho cov khoom yuav tsum yog corrosion- tiv taus rau sab nraum zoov.
2. Kev tsim qauv ntawm kev sib koom ua ke cuam tshuam li cas rau kev sib koom ua ke ntawm txoj kev tsheb ciav hlau?
Kev sib koom ua ke tsim kev txiav txim siab npaum li cas cov khoom thauj tau raug xa mus ntawm cov kab tsheb ciav hlau. Curved sib koom tuav muab kev faib khoom zoo dua li cov qauv tsim ncaj. Lub thickness thiab ntev ntawm cov khoom sib koom ua ke cuam tshuam lawv lub zog thiab yoog raws. Tsim kom raug tuav txo qis kev ntxhov siab ntawm kev tsheb ciav hlau kawg. Niaj hnub nimno cov khoom sib koom ua ke feem ntau muaj cov kab sib txuas kom txo tau cov quab yuam.
3. Dab tsi yog qhov yuav tsum tau ua ntawm kev saib xyuas rau insulated rail sib txuas?
Insulated rail pob qij txha yuav tsum tau kuaj hluav taws xob tsis tu ncua kom ntseeg tau tias muaj kev rwb thaiv tsev zoo. Cov ntaub ntawv insulating yuav tsum tau kuaj xyuas qhov hnav lossis tawg. Bolt rwb thaiv tsev lub tes tsho yuav tsum tau kuaj xyuas qhov kev puas tsuaj. Rail kawg ncej insulators yuav tsum tau hloov raws sij hawm. Tshwj xeeb tsis yog-cov roj lubricants yuav tsum tau siv los tswj cov hluav taws xob sib cais.
4. Yuav ua li cas expansion pob qij txha txawv ntawm cov qauv kev tsheb nqaj hlau?
Expansion pob qij txha tso cai rau thermal expansion thiab contraction ntawm rails. Lawv feature tshwj xeeb zawv zawg mechanisms lossis qhov sib txawv tsim. Tsis zoo li cov qauv pob qij txha, lawv ua kom haum rau qhov ntev ntev. Cov pob qij txha nthuav dav yog qhov tseem ceeb hauv thaj chaw uas muaj qhov kub thiab txias hloov pauv. Lawv cov qauv tsim tiv thaiv kev tsheb ciav hlau buckling nyob rau hauv huab cua kub thiab qhov khoob hauv huab cua txias.
5. Dab tsi yog qhov zoo ntawm kev siv cov khoom siv zoo tshaj plaws rau cov pob qij txha?
Premium alloy steels muab lub zog zoo tshaj - rau - qhov hnyav piv. Lawv ua kom pom kev qaug zog zoo heev hauv kev rov ua dua. Cov ntaub ntawv no tau txhim kho kev hnav tsis kam rau kev ua haujlwm ntev dua. Alloy steels tswj cov cuab yeej cuab tam hauv qhov kub thiab txias. Lawv corrosion kuj txo cov kev xav tau ntawm kev saib xyuas.
