Fishplate Material Classification thiab Compatibility Standards
Dab tsi yog cov ntaub ntawv thiab cov xwm txheej siv tau ntawm cov ntses zoo tib yam?
Ordinary fishplates feem ntau yog ua los ntawm Q235 thiab Q345 steel, nrog rau tag nrho - hlau qauv thiab tsis muaj txheej insulating. Hom phaj ntses no muaj tus nqi qis, kev siv tshuab ua haujlwm yooj yim thiab kev teeb tsa yooj yim, thiab tsim nyog rau cov uas tsis yog - hluav taws xob railways lossis ntu tsis muaj kev sib tw khiav. Piv txwv li, cov kab kev thauj khoom zoo tib yam, kev lag luam thiab tsuas yog cov kab tshwj xeeb thiab lwm cov kab uas tsis muaj qhov yuav tsum tau ua rau kev ua haujlwm rwb thaiv tsev thiab tsuas yog yuav tsum tau ua kom tau raws li qhov yuav tsum tau muaj zog ntawm txoj kev tsheb ciav hlau. Q235 cov khoom siv ntses yog tsim rau cov kab tsheb ciav hlau nrog cov khoom me me, thaum Q345 cov khoom siv tuaj yeem siv rau cov kab nrawm nrog cov khoom nruab nrab. Thaum siv, nws yog ib qho tsim nyog los xyuas kom meej tias cov phaj phaj sib phim cov kev tsheb ciav hlau kom raug kom tsis txhob xoob kev sib txuas.
Dab tsi yog cov yam ntxwv ntawm cov qauv thiab cov haujlwm tseem ceeb ntawm insulated fishplates?
Insulated fishplates ntxiv cov ntaub ntawv insulating ntawm lub cev hlau, thiab cov khoom siv insulating feem ntau yog siab -kub resistant thiab aging resistant fiberglass board. Nws lub luag haujlwm tseem ceeb yog txhawm rau thaiv kev sib kis ntawm kev khiav tam sim no, tiv thaiv tam sim no los ntawm kev cuam tshuam nrog cov teeb liab khiav, thiab xyuas kom muaj kev tswj hwm kev ua haujlwm ntawm cov tsheb ciav hlau. Hom ntses phaj no tsuas yog siv rau hauv cov kab hluav taws xob ntawm cov hluav taws xob railways, thiab yog ib qho tseem ceeb ntawm cov teeb liab kis tau tus mob. Cov khoom siv insulating yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua kom ntev - siv sab nraum zoov thiab tiv thaiv kev yaig ntawm ib puag ncig xws li cua, nag thiab kub sib txawv. Thaum lub sij hawm installation, yuav tsum tau them nyiaj mloog mus rau kev tiv thaiv lub insulating txheej kom tsis txhob muaj kev puas tsuaj ntawm rwb thaiv tsev los ntawm kev sib tsoo los yog extrusion, uas yuav cuam tshuam rau cov kab teeb liab.
Yuav ua li cas los txiav txim tus naj npawb thiab specification ntawm bolts rau fishplates raws li tus qauv rail?
Lub bolt configuration ntawm fishplates yuav tsum tau raws li lub tsheb ciav hlau qhov hnyav thiab load yuav tsum. Lub phaj sib npaug 43kg / m rail yog nruab nrog 4 bolts ib kawg, thiab cov lus qhia feem ntau yog M22. Hom kev tsheb ciav hlau no yog lub teeb hauv qhov hnyav thiab muaj qhov me me, yog li 4 bolts tuaj yeem ua tau raws li qhov xav tau ntawm kev xa khoom. Cov ntses phaj rau 50kg / m thiab 60kg / m rails yog nruab nrog 6 bolts ib kawg, nrog rau specification ntawm M24. Raws li kev tsheb ciav hlau qhov hnyav nce thiab kev thauj khoom nce, nce tus naj npawb thiab cov ntsiab lus ntawm bolts tuaj yeem cuam tshuam kev ntxhov siab thiab tsis txhob muaj kev ntxhov siab ntawm qhov sib koom ua ke. Cov phaj ntses rau 75kg / m hnyav- tsheb ciav hlau yog nruab nrog 8 bolts ib kawg, nrog rau qhov tshwj xeeb ntawm M27. Cov kab hnyav-haul kab muaj lub qag load ntau dua los yog sib npaug li 30t, thiab ntau dua -sized bolts yog xav tau los txhim kho kev sib txuas lub zog thiab tiv thaiv kev sib tsoo lossis deformation. Qhov kev txiav txim siab yog nyob ntawm tus qauv tsim, hla- ntu qhov ntev thiab cov khoom siv hluav taws xob ntawm txoj kev tsheb ciav hlau kom ntseeg tau tias qhov kev sib txuas lub zog sib npaug ntawm lub cev tsheb ciav hlau.
Dab tsi ua haujlwm yuav tsum tau tsom mus rau thaum xaiv cov phaj rau hnyav -cov kab?
Hnyav- cov kab tsheb thauj khoom muaj qhov xav tau siab heev ntawm lub zog, hnav tsis kam thiab qaug zog tiv thaiv ntawm cov phaj ntses. Ua ntej, nws yuav tsum muaj lub zog tensile txaus thiab shear lub zog los tiv thaiv qhov cuam tshuam loj heev tsim los ntawm hnyav- tsheb ciav hlau; thib ob, nws yuav tsum muaj kev hnav zoo heev los txo qhov hnav ntawm qhov sib koom ua ke thaum lub tsheb ciav hlau hla; tib lub sijhawm, nws yuav tsum muaj kev qaug zog zoo kom tsis txhob muaj cov kab nrib pleb tshwm sim los ntawm qhov ntev - lub sij hawm rov ua dua. Feem ntau hnyav- cov kab tsheb thauj khoom siv cov ntaub ntawv muaj zog ntawm Q345 thiab siab dua, thiab qee qhov tshwj xeeb tau txais cov ntaub ntawv hlau alloy los txhim kho kev ua tau zoo. Kev ua tiav ntawm cov phaj phaj kuj yuav tsum tau tswj xyuas kom nruj kom haum nrog txoj kev tsheb ciav hlau thiab txo kev puas tsuaj los ntawm kev co.
Dab tsi yog qhov ua txhaum ntawm fishplates tom qab kev teeb tsa thiab lawv cov kev tiv thaiv?
Feem ntau cov faults ntawm fishplates tom qab installation muaj xws li bolt loosening, rwb thaiv tsev txheej puas, hnav ntau dhau ntawm pob qij txha thiab tawg tiam. Txhawm rau tiv thaiv lub bolt loosening, nruj raws li lub zog torque, ua haujlwm tsis tu ncua - zawm tshuaj xyuas, thiab siv cov roj tiv thaiv tshwj xeeb rau cov ntsia liaj qhov rooj. Txhawm rau kom tsis txhob muaj kev puas tsuaj ntawm cov txheej txheem rwb thaiv tsev, ua tib zoo saib xyuas thaum lub sijhawm teeb tsa thiab kev thauj mus los kom tsis txhob cuam tshuam los ntawm cov khoom tawv; ntxuav cov khib nyiab ntawm qhov sib koom ua ke hauv lub sijhawm tom qab kev teeb tsa kom tsis txhob nyem cov txheej txheem rwb thaiv tsev. Txhawm rau txo qis kev sib koom ua ke, xyuas kom meej tias lub phaj phaj haum zoo nrog txoj kev tsheb ciav hlau kom tsis txhob muaj qhov khoob khoob uas ua rau muaj kev vibration ntxiv; tsis tu ncua xyuas qhov sib koom ua ke thiab zom cov khoom tsis sib xws hauv lub sijhawm. Txhawm rau tiv thaiv cov kab nrib pleb, xaiv cov nplais ntawm cov khoom tsim nyog, tsis txhob overloading, thiab tsis tu ncua xyuas qhov tsis xws luag los ntawm qhov tsis zoo.
