Railway Fastener Cov Ntawv: Cov neeg saib xyuas qhov tsis pom ntawm kev nyab xeeb

Tom qab lub siab - Cov tsheb ciav hlau ceev cov lus dag ib txwm muaj qhov ntau tshaj plaws: kev tsheb ciav hlau nrawm nrawm. Cov hlua khi zoo li no yooj yim, cov noob txiv, cov tshuab ntxhua khaub ncaws, thiab lub zog tseem ceeb uas ua kom muaj kev ruaj khov ntawm kev tsheb ciav hlau cov qauv thiab kev nyab xeeb ntawm kev qhia kev qhia. Lawv nyob ntsiag to tiv thaiv lub tsheb ciav hlau, qhov kev hloov pauv, thiab kev poob siab, ua kom ncaj qha tswj kev ntseeg tau ntawm tag nrho cov kev tsheb ciav hlau network.

Lub pob zeb hauv pob zeb ntawm cov qauv pauv nrawm

Lub sijhawm ua haujlwm ntawm kev railway fasteners yog kom ruaj ntseg rails rau cov neeg tsaug zog rau cov neeg tsaug zog lossis trackbed. Nyob rau hauv ib txwm ballasted track, neeg nplua nuj (tseem hu ua kev tsheb nqaj hlau nrog high sharm bolts, tsim lub nra ruaj khov {{bearing system. Nyob rau hauv ballastless txoj kev, kos lub tes tsho thiab lub caij nplooj ntoos hlav ceev ncaj qha kaw cov ntsia hlau rau cov pob zeb ua ke geometry. Lub zog tensile thiab qaug zog lub neej ntawm cov fasteners ncaj qha cuam tshuam ntev- lub sij hawm ruaj khov ntawm txoj kev khiav. Txhua txoj kev txo qis yuav ua rau kev mob siab rau kev pheej hmoo thiab ua rau kev pheej hmoo txaus ntshai.

Tus yuam sij rau kev tawm tsam cov khoom siv hluav taws xob dynamic

Cov khoom siv hluav taws xob muaj zog tsim los ntawm kev tsheb ciav hlau hauv kev ua haujlwm tuaj yeem ua ntau lub sijhawm ntau dua li qub. Coupled nrog lub caij nyoog cuam tshuam ntawm lub log - kev sib tw sib cuag, cov tsheb ciav hlau yog tas li- zaus kev co. Fasteners yuav tsum muaj cov khoom elasticity zoo thiab damping cov khoom kom zoo hloov cov khoom thauj khoom thiab tsis muaj kev co lub zog. Piv txwv li, kev sib xyaw ua ke tsim ntawm txoj kev sib xyaw ntawm cov ntaub qhwv ntsej muag thiab cov fasteners tuaj yeem nqus tau txog 60% ntawm kev cuam tshuam lub zog, txo cov fretting ntawm kev ntsia thiab pw tsaug zog. Nyob rau siab - Ceev cov kab ciav hlau, tshwj xeeb tsim cov tsheb ciav hlau loj heev uas tau tsim los ntawm high} qib kom raug txawm tias ntawm kev ceev ntawm 350 km / h.

Cov qauv tsim qauv adjective adapts rau kev hloov ib puag ncig

Los ntawm frigid Northast Plains mus rau qhov scorching sab qab teb Suav teb, railway fasteners yuav tsum wawster ntau heev los ntawm {}} 40℃rau 80 degree. Thermal expansion thiab mroundaction yuav ua rau kev nthuav dav thiab mob contraction yuav tsum tso cai rau tsim nyog kho cov npoo thiab kev lag luam ntsuas kub. Kev siv cov hlau stainless thiab anti {- corrosion coasings kom ntseeg tau lub neej ntev tshaj 30 xyoo hauv kev ua kom huv si xws li cov tshuaj huv si ntsev. Cov lus soj ntsuam tshwm sim tsis ntev los no muaj peev xwm muab cov lus qhia tiag tiag ntawm cov rooj sib tw ntawm cov sensors, muab cov kev txaus ntshai thaum ntxov ntawm cov peev xwm txo qis.

Kev Tshawb Fawb Kev Tshawb Fawb thiab Yav Tom Ntej Cov Lus Qhia

Nrog rau kev txhim kho ntawm hnyav - haul thiab siab} Kev ceev ceev, thiab txij nkawm {2} Cov kev cai pub dawb. Kev xaiv lub fasteners tshiab yog 30% kev sib zog ua kom muaj zog dua, thiab tus kheej- Txoj kev sib tw ntawm kev sib tw ntawm ib txwm re} {zawm. Nyob rau hauv lub sij hawm era ntawm cov ntse ntse, fasteners nrog cov kev saib xyuas kev sib xyaw ua ke hauv kev saib xyuas kev noj qab haus huv, muab cov ntaub ntawv tseem ceeb rau kev saib xyuas. Cov thev naus laus zis txuas ntxiv ua rau cov neeg tiv thaiv "uas pom tau" ntawm qhov tseeb ntawm kev tsheb nqaj hlau thev naus laus zis.

Los ntawm cov bolts yooj yim nyob rau hauv chav locomotive era rau lub sensor {}}} ceev}}} kev kub siab ntawm tib neeg txoj kev tsheb thauj mus los. Txawm hais tias lawv feem ntau zais hauv qab cov ciav hlau, txhua qhov kev qhia du yog qhov muaj peev xwm ua rau cov neeg kho tshuab ua kom zoo nkauj no.
