Kev Xaiv Cov Ntsiab Cai rau Rail thiab Fastening System Compatibility
Dab tsi yog lub hauv paus ntsiab lus ntawm kev hloov pauv ntawm cov qauv tsheb ciav hlau thiab qhov system fastening?
Lub hauv paus ntsiab lus tseem ceeb yog load txuam; tus qauv kev tsheb nqaj hlau txiav txim siab lub load-cov kabmob muaj peev xwm, thiab lub kaw lus fastening yuav tsum muab lub zog sib xws ntawm kev kho lub zog. Lub teb chaws tus qauv 43kg / m thiab 50kg / m rails yog tsim rau lub zog zoo tib yam elastic rail clips, bolts, thiab nias daim hlau . 60kg / m thiab 75kg / m hnyav- cov tsheb ciav hlau yuav tsum tau sib tw nrog siab - lub zog fastening Cheebtsam, xws li U75V cov ntaub ntawv bolts thiab tuab. Kev kho kom haum yuav tsum xyuas kom meej tias cov theem ntawm lub zog ntawm tag nrho cov Cheebtsam yog zoo ib yam, tsis txhob "muaj zog rail thiab tsis muaj zog Cheebtsam" los yog "tsis muaj zog rail thiab muaj zog Cheebtsam". Hom kev khiav kuj yuav tsum tau txiav txim siab; lub fastening system ntawm ballastless lem yuav tsum tau txhim khu elasticity thiab rwb thaiv tsev kev ua tau zoo. Lub hom phiaj tseem ceeb ntawm kev hloov pauv yog kom paub txog kev ua haujlwm sib koom ua ke ntawm txoj kev tsheb ciav hlau thiab lub kaw lus fastening thiab ua kom muaj kev nyab xeeb tag nrho ntawm txoj kev.
Yuav ua li cas xaiv cov qauv rau kab sib txawv load theem?
Rau cov kab tsheb thauj khoom zoo tib yam (xws li cov tsheb ciav hlau hauv zos thiab cov kab tshwj xeeb), U71Mn lub teb chaws tus qauv kev tsheb nqaj hlau tuaj yeem xaiv, sib tw nrog Q235 cov khoom siv bolts, zoo tib yam elastic rail clips, thiab roj hmab puag daim hlau. Rau cov kab nruab nrab thauj khoom (xws li txoj kev tsheb ciav hlau), U75V lub teb chaws tus qauv kev tsheb nqaj hlau lossis European S355Jr rails tuaj yeem xaiv, ua ke nrog 45 # steel bolts thiab cov pa clamping quab yuam elastic rail clips. Rau cov kab thauj khoom hnyav (xws li Daqin Railway), U75V lub teb chaws tus qauv kev tsheb nqaj hlau lossis American AAR M102 Qib 115 rails yuav tsum tau xaiv, sib tw nrog 35CrMoA siab- lub zog bolts thiab siab - cov ntawv sib xyaw ua ke. Siab- cov kab tsheb thauj mus los ntau zaus yuav tsum tau ntxiv dag zog rau kev qaug zog ntawm cov khoom siv, xaiv cov hlua khi hlua khi thiab cov hlua khi ntawm hnav- cov ntaub ntawv tiv taus. Kev xaiv thauj khoom yuav tsum raug txiav txim siab raws li qhov tsim lub qag load, ntim kev thauj mus los, thiab kev khiav hauj lwm ceev ntawm txoj kab.
Dab tsi cuam tshuam rau ib puag ncig yam cuam tshuam rau kev xaiv qauv?
Rau siab - qhov kub thiab txias ib puag ncig, cov cua sov- cov kab hluav taws xob tiv thaiv yuav tsum tau xaiv, xws li cov ntsia hlau uas muaj chromium thiab molybdenum thiab siab - kub resistant roj hmab puag phaj. Rau qis- qhov kub thiab txias ib puag ncig, rails nrog zoo qis- kub toughness yog nyiam, xws li Lavxias teb sab GOST R 51685 rails, thiab hlau Cheebtsam uas muaj zog Frost tsis kam. Rau qhov chaw ntub dej thiab ntug dej hiav txwv, txhua yam khoom siv los tiv thaiv - yuav tsum tau xaiv, xws li galvanized bolts, ceramic puag phaj, thiab cov ntawv sib xyaw ua ke. Rau thaj chaw suab puam, yuav tsum xav txog kev tiv thaiv tshav kub thiab tiv thaiv plua plav, xaiv cov txheej txheem fastening nrog kev ua tau zoo sealing thiab hnav{10}} cov hlua tiv thaiv. Lub hauv paus ntawm kev xaiv ib puag ncig yog los xyuas kom meej tias cov khoom muaj peev xwm tswj tau qhov kev ua haujlwm ruaj khov nyob rau hauv cov xwm txheej huab cua thiab txuas ntxiv kev pab cuam lub neej.
Yuav ua li cas xaiv tus qauv ua tau raws li cov qauv kev lag luam?
Lub teb chaws tus qauv kab yuav tsum nruj me ntsis ua raws li GB / T 2585 rail qauv thiab TB / T 2347-93 bolt tus qauv los xyuas kom meej cov khoom ua raws. Cov kab hluav taws xob European yuav tsum ua raws li EN 13674-1 rail standard thiab UIC fastener tus qauv. Cov kab hauv Teb Chaws Asmeskas yuav tsum ua raws li AREMA rail tus qauv thiab cov txheej txheem fastener sib raug. Thaum xaiv cov qauv, nws yog ib qho tsim nyog los xyuas qhov loj me, cov khoom siv, cov khoom siv kho tshuab thiab lwm yam tsis zoo ntawm cov khoom kom ntseeg tau tias lawv ua tau raws li tus qauv yuav tsum tau ua. Kev hloov kho thiab rov ua dua tshiab ntawm cov qauv kuj yuav tsum tau txiav txim siab, thiab cov khoom lag luam uas ua tau raws li cov qauv tshiab yuav tsum raug xaiv raws sijhawm. Kev xaiv tus qauv ua raws yog qhov yuav tsum tau ua ua ntej txhawm rau ua kom paub tseeb txog kev lees paub engineering thiab kev ua haujlwm nyab xeeb.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev txheeb xyuas thiab kev hloov kho tom qab xaiv cov qauv?
Tom qab xaiv cov qauv, cov kev xeem thauj khoom yuav tsum tau kuaj xyuas cov kev sib koom ua ke ntawm txoj kev tsheb ciav hlau thiab kev ceev ceev kom ntseeg tau tias nws ua tau raws li cov qauv tsim. Tom qab kev teeb tsa hauv ntu kev tsav tsheb, saib xyuas kev hloov tsheb ciav hlau, tiv thaiv kev qaug zog, thiab taug qab smoothness. Kho cov khoom tsis sib xws raws li cov ntaub ntawv soj ntsuam, xws li hloov cov paib sib txawv ntawm qhov sib txawv nruj los yog elastic rail clips ntawm cov clamping sib txawv. Tsis tu ncua sau cov ntaub ntawv ua haujlwm kab, sib piv qhov xav tau thiab qhov tshwm sim tiag tiag ntawm kev xaiv cov qauv, thiab ua kom zoo dua cov qauv xaiv cov qauv tom ntej. Rau ib puag ncig tshwj xeeb lossis cov kab thauj khoom nyuaj, yuav tsum muaj kev sim tshwj xeeb los xyuas kom muaj kev tshawb fawb thiab kev ntseeg siab ntawm kev xaiv qauv. Kev txheeb xyuas thiab kev hloov kho tuaj yeem pom cov qauv xaiv qhov sib txawv raws sijhawm thiab xyuas kom lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm kev khiav haujlwm.
