Fishplate thiab Rail Joint Connection Technology
Dab tsi yog qhov yuav tsum tau siv tshuab yuav tsum xaiv cov khoom ntawm fishplates ua tau raws li?
Cov khoom ntawm fishplates yuav tsum phim cov khoom siv rail; siab -lub zog alloy steels xws li 40CrMnMo feem ntau yog siv los xyuas kom meej tias lub zog tensile thiab lub zog tawm los nyob ze rau cov ntsia hlau. Cov khoom siv yuav tsum muaj qhov zoo toughness thiab qaug zog, thiab tuaj yeem tiv taus kev cuam tshuam rov qab thaum cov tsheb ciav hlau hla kev sib koom ua ke. Fishplates yuav tsum tau txais kev kho cua sov los txhim kho qhov tawv tawv thiab hnav tsis kam, ncua kev pab cuam lub neej. Lawv qhov elongation tus nqi yuav tsum ua tau raws li qee cov qauv kom tsis txhob nkig tawg ntawm kev sib koom ua ke hauv kev ntxhov siab. Cov khoom siv kuj yuav tsum muaj kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ntug dej hiav txwv thiab alpine ib puag ncig, thiab kev tiv thaiv corrosion yuav tsum tau txhim khu kev ruaj ntseg.
Dab tsi yog cov ntsiab lus technical ntawm fishplate seem tsim?
Cov seem ntawm cov phaj ntses yuav tsum haum rau cov duab ntawm lub taub hau tsheb ciav hlau, lub vev xaib thiab lub hauv paus kom ntseeg tau tias muaj zog sib xws tom qab kev sib txuas thiab txo qis kev ntxhov siab. Qhov luaj li cas yuav tsum tau tswj kom meej- qhov sib txawv loj lossis me me nrog txoj kev tsheb ciav hlau yuav cuam tshuam rau kev sib koom ua ke, thiab qhov sib txawv feem ntau yog tswj tsis pub dhau 0.5 hli. Txoj hauj lwm thiab tus naj npawb ntawm cov ntsia liaj qhov rooj ntawm lub phaj phaj yuav tsum tau tsim raws li cov qauv kev tsheb nqaj hlau kom ntseeg tau tias muaj kev sib faib ntawm cov ntsia hlau clamping quab yuam. Qee cov phaj ntses tau txais kev nthuav dav thiab tuab tsim los txhim kho kev sib koom ua ke, ua raws li cov kev xav tau ntawm cov kab hnyav -cov kab. Tshooj tsim kuj yuav tsum xav txog kev yooj yim installation, ua kom yooj yim rau ntawm - qhov chaw sib dhos thiab tu.
Dab tsi yog qhov yuav tsum tau muaj rau kev koom tes ntawm fishplates thiab bolts?
Fishplates thiab bolts yuav tsum tau siv ua ke; cov ntsia liaj qhov rooj specification yuav tsum tau txiav txim raws li lub fishplate thickness thiab rail qauv los xyuas kom meej txaus clamping quab yuam. Thaum zawm bolts, qhov tshwj xeeb torque yuav tsum tau siv nyob rau hauv ib ntus kom tsis txhob muaj kev sib koom ua ke vim qhov tsis txaus torque los yog ntsia liaj qhov rooj tawg vim lub zog ntau dhau. Lub bolt qhov ntawm lub phaj phaj yuav tsum tau chamfered kom txo tau kev ntxhov siab thaum lub sij hawm ntsia liaj qhov rooj. Elastic ntxhua khaub ncaws tuaj yeem ntsia nruab nrab ntawm lub bolts thiab fishplates los txhim kho kev tiv thaiv -loo kev ua tau zoo thiab tiv thaiv kev vibrations los ntawm lub tsheb ciav hlau ua haujlwm. Qhov sib txawv haum yuav tsum nruj me ntsis tswj kom tsis txhob bolt loosening lossis fishplate deformation, cuam tshuam rau kev sib koom ua ke.
Dab tsi yog qhov sib txawv ntawm kev ua tau zoo rau cov ntses ntses hauv ntau hom kab?
Fishplates rau txoj kev tsheb ciav hlau zoo tib yam tsom rau kev ntseeg tau thiab kev lag luam, xav tau kom ua tau raws li qhov kev xav tau ntawm kev thauj khoom ceev Tsawg dua lossis sib npaug li 160km / h nrog lub zog tensile Ntau dua lossis sib npaug ntawm 880MPa. High- cov kab tsheb ciav hlau ceev muaj qhov xav tau ntau dua rau qhov tawv thiab du ntawm cov ntses; Cov qauv tsim tshwj xeeb yuav tsum tau txo lub log- kev tsheb nqaj hlau cuam tshuam ntawm kev sib koom ua ke thiab ua kom ruaj khov ua haujlwm ntawm qhov nrawm dua lossis sib npaug li 300 km / h. Fishplates rau hnyav- cov kab tsheb yuav tsum muaj peev xwm ua tau ntau dua, feem ntau yog ua los ntawm siab- lub zog alloy steel, thiab cov bolts tuaj yeem tsim nyog ntxiv los txhim kho kev sib koom ua ke. Fishplates rau kev tsheb ciav hlau hauv nroog yuav tsum sib npaug ntawm kev vibration thiab suab nrov txo, thiab cov qauv tsim elastic tuaj yeem raug coj los ua kom txo qis kev co thiab suab nrov. Fishplates rau cov kab ib puag ncig huab cua yuav tsum muaj huab cua tiv thaiv, ua kom haum rau kev ua haujlwm los ntawm kev tiv thaiv{11}} xeb thiab tiv thaiv - kev kho mob khov.
Dab tsi yog cov kauj ruam tseem ceeb hauv kev teeb tsa thiab kev saib xyuas ntawm fishplates?
Ua ntej kev teeb tsa, xyuas qhov flatness ntawm cov ntses phaj thiab cov tsheb ciav hlau sib koom ua ke, tshem tawm cov impurities thiab xeb ntawm qhov sib koom ua ke kom nruj nruj. Fishplates yuav tsum tau nruab symmetrically, thiab bolts yuav tsum tau nruj nyob rau hauv txoj kab pheeb ces kaum, maj mam siv lub torque teev kom tsis txhob sib zog quab yuam. Tom qab kev teeb tsa, xyuas qhov sib koom ua ke kom paub tseeb tias nws tsis pub dhau qhov kev tso cai, thiab ib txhij kuaj xyuas seb qhov ntsuas puas ua tau raws li tus qauv. Hauv kev tu txhua hnub, tsis tu ncua xyuas seb lub phaj phaj puas muaj cov kab nrib pleb lossis deformation, thiab seb cov bolts puas xoob lossis xeb. Kev daws teeb meem raws sij hawm, hloov cov phaj phaj thiab bolts puas, thiab zam kev nyab xeeb los ntawm kev sib koom ua ke.
