Fishplate Material thiab Installation Knowledge
Dab tsi yog qhov tseem ceeb ntawm fishplates?
Lub luag haujlwm tseem ceeb ntawm fishplates yog txhawm rau txuas ob txoj hlua uas nyob ib sab los tsim cov qauv kev txuas mus ntxiv, kom ntseeg tau tias cov tsheb ciav hlau hla kev sib koom ua ke. Nws zoo haum rau txoj kev tsheb ciav hlau xaus los ntawm bolt fixation los tiv thaiv longitudinal hloov chaw thiab transverse misalignment ntawm cov ntsia hlau. Nws tuaj yeem xa cov quab yuam ntawm cov ntsia hlau, ua rau lub tsheb ciav hlau thauj khoom sib npaug sib npaug, thiab txo qhov kev ntxhov siab ntawm qhov sib koom ua ke. Cov qauv tsim ntawm lub phaj phaj tuaj yeem cuam tshuam lub zog cuam tshuam thaum lub tsheb ciav hlau hla, txo qhov hnav ntawm qhov sib koom ua ke. Hauv kev saib xyuas, cov phaj ntses kuj pab txhawb kev tshem tawm thiab hloov cov ntsia hlau, txhim kho kev tsim kho kom zoo.
Dab tsi yog cov khoom siv ntawm fishplates?
Cov khoom siv dav dav ntawm cov phaj ntses muaj xws li Q235 carbon steel, uas muaj tus nqi qis thiab lub zog nruab nrab, tsim nyog rau cov kab nrawm nrawm. Nodular cam khwb cia hlau fishplates muaj lub zog siab, hnav tsis kam thiab qaug zog ua haujlwm, haum rau nruab nrab thiab siab - cov kab thauj khoom. Forged alloy steel muaj zoo heev lub zog thiab toughness, ua rau nws yog ib qho zoo tagnrho xaiv rau hnyav-haul thiab siab- ceev railways. Bainitic steel fishplates muaj qhov tsis zoo - qhov kub thiab txias tsis kam, tshwj xeeb tshaj yog haum rau kev taug qab ib puag ncig hauv cheeb tsam txias. Polyurethane composite fishplates muaj rwb thaiv tsev, lub teeb yuag thiab corrosion kuj, haum rau insulated pob qij txha thiab electrified seem.
Dab tsi yog qhov kev ua tau zoo ntawm fishplates?
Lub zog tensile ntawm fishplates yuav tsum muaj ntau dua los yog sib npaug rau 780MPa kom ntseeg tau tias lawv tuaj yeem tiv taus lub nra thiab cuam tshuam lub zog xa los ntawm cov ntsia hlau. Nws tseem yuav tsum tau tswj kom muaj kev cuam tshuam zoo hauv qhov qis - qhov kub thiab txias ntawm -30℃kom tsis txhob muaj qhov kub thiab txias nkig tawg. Nws muaj kev tiv thaiv zoo heev thiab qaug zog, thiab tuaj yeem tiv taus qhov kev co thiab kev sib txhuam los ntawm kev rov ua dua ntawm cov tsheb ciav hlau. Corrosion tsis kam yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov av noo, ntug hiav txwv dej thiab lwm qhov chaw corrosive, uas tuaj yeem ua rau lub neej ntev. Kev ua haujlwm raug ntawm cov khoom siv yuav tsum ua kom tau raws li tus qauv kom ntseeg tau tias muaj kev sib raug zoo nrog cov tsheb ciav hlau tsis muaj qhov khoob.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm cov ntses ntses?
Ua ntej kev teeb tsa, txoj kev tsheb ciav hlau kawg lub ntsej muag thiab lub qhov ntsia hlau yuav tsum tau muab ntxuav kom huv si kom tshem tawm xeb, roj thiab lwm yam impurities kom haum. Thaum lub sij hawm installation, txhawb nqa ntses bolt, locknuts thiab caij nplooj ntoos hlav ntxhua khaub ncaws yuav tsum tau xaiv los xyuas kom meej cov nyhuv fastening. Tighten lub bolts nyob rau hauv ib tug ntoo khaub lig-tightening yam kom tsis txhob fishplate deformation vim tsis muaj zog. Lub ntsia liaj qhov rooj zawm torque yuav tsum ua tau raws li cov qauv tsim, feem ntau ntawm 500-700N·m, kom ruaj khov kho. Tom qab kev teeb tsa, xyuas qhov nruj ntawm lub phaj phaj thiab cov tsheb ciav hlau, xyuas kom tsis muaj qhov xoob lossis qhov khoob kom ntseeg tau tias kev sib koom ua ke.
Yuav ua li cas xaiv fishplates raws li kab hom?
Q235 carbon steel fishplates tuaj yeem xaiv tau rau cov kab nrawm nrawm los tswj cov nqi thaum ua tau raws li cov kev cai siv yooj yim. Nodular cam khwb cia hlau fishplates yuav tsum tau xaiv rau nruab nrab thiab siab - cov kab thauj khoom, ntsuas lub zog thiab kev lag luam. Hnyav- txoj kev tsheb ciav hlau yuav tsum xaiv forged alloy steel fishplates, uas nws lub zog siab thiab tawv tuaj yeem tiv taus lub nra loj. Rau cov kab hauv cheeb tsam txias, bainitic steel fishplates yuav tsum tau nyiam los tiv thaiv kev cuam tshuam nyob rau hauv qis - qhov kub thiab txias. Rau cov seem hluav taws xob lossis cov pob qij txha uas xav tau kev rwb thaiv tsev, polyurethane composite insulated fishplates yuav tsum raug xaiv.
