Taug qab Fastening Systems: Ua kom tiav Cov Txheej Txheem Sib Tw thiab Scenario-Txoj Kev Xaiv
Dab tsi yog plaub hom fastening tshuab thiab cov xwm txheej siv tau?
High-Speed railway elastic fastening system muaj xws li W2/X3 elastic strips, 10.9 qib insulating bolts thiab roj hmab puag daim hlau, haum rau siab -ceev railway ballastless lem, nrog triple functions ntawm xauv, poob siab absorbing thiab rwb thaiv tsev, ua tau raws li siab -ceev tsav tsheb xav tau kev pab. Ordinary railway rigid fastening system muaj xws li Hom Ⅰ elastic strips, 8.8 qib zoo tib yam bolts thiab composite puag daim hlau, haum rau zoo tib yam railway ballasted lem, nrog cov qauv yooj yim, ruaj khov, tus nqi pheej yig thiab yooj yim installation. Kev lag luam thiab mining hnyav- lub luag haujlwm fastening system suav nrog cov hlua khi tuab, 12.9 qib siab- lub zog bolts thiab hnav- cov paib tiv taus, haum rau mine / chaw nres nkoj hnyav- lub luag haujlwm lem, cuam tshuam resistant thiab tiv thaiv - xoob, tiv taus cov khoom hnyav dov. Cov txheej txheem txawv teb chaws ua tiav cov txheej txheem fastening tau muab faib ua UIC / BS / AREMA qauv, siv nrog cov txheej txheem txawv teb chaws sib xws, ua raws li cov qauv kev lag luam thoob ntiaj teb, tsim nyog rau kev hla - ciam teb railway tej yaam num. Accessories ntawm plaub lub tshuab tsis tuaj yeem sib xyaw, thiab tag nrho cov txheej txheem yuav tsum tau nruab raws li qib kab kom ntseeg tau tias tag nrho kev ruaj ntseg ntawm txoj kev khiav.
Dab tsi yog lub hauv paus ntsiab lus ntawm fastening system accessory txuam?
Fastening system accessories yuav tsum ua raws li lub hauv paus ntsiab lus ntawm ib tug - mus rau - ib qho piv ntawm rail specifications, 50kg / m rails nrog 50- hom accessories, 60kg / m rails nrog 60- hom accessories, zam installation qhov khoob los ntawm mismatched specifications. Elastic strip buckling force yog synchronized nrog lub zog bolt, high-speed railway elastic strips nrog 10.9 qib bolts, zoo tib yam railway elastic strips nrog 8.8 qib bolts, lub zog tsis sib haum yuav ua rau lub xauv tsis ua haujlwm. Lub hauv paus phaj thickness yog yoog raws kev sib haum xeeb, tuab daim hlau rau qhov chaw sib hais thiab nyias daim hlau rau cov qauv seem kom ntseeg tau tias kev tsheb ciav hlau. Rwb thaiv tsev yuav tsum tau teeb tsa raws li qhov xav tau, kev kub ceev tsheb ciav hlau yuav tsum tau ntxiv cov khoom siv rwb thaiv tsev, kev tsheb ciav hlau zoo tib yam / kev lag luam thiab cov tshuab mining tuaj yeem tshem tawm lawv, txo nqi thaum lub rooj sib tham ua haujlwm. Cov khoom siv khoom siv yuav tsum ua raws li tus qauv sib koom ua ke, lub teb chaws tus qauv khoom siv nrog cov khoom siv hauv teb chaws, cov khoom siv txawv teb chaws nrog cov khoom siv txawv teb chaws, tshem tawm kev ntxhov siab tsis sib xws los ntawm cov khoom sib xyaw.
Dab tsi yog qhov tseem ceeb ntawm cov khoom siv sib txawv ntawm qhov siab - ceev thiab cov kab tsheb ciav hlau zoo tib yam?
High -Speed railway elastic strips yog W2/X3 elastic type with buckling force>=10kN and fatigue life greater than or equal to 5 lab times, adapting to high-frequency vibration of high-speed railways; Txoj kev tsheb ciav hlau zoo tib yam elastic strips yog Hom Ⅰ rigid hom nrog buckling quab yuam Ntau dua los yog sib npaug rau 6kN, ntsib qhov yooj yim xauv nkaus xwb. High-Speed railway bolts yog 10.9 qib insulated hom nrog insulating txheej tiv thaiv-electrocorrosion, torque 500-550N·m; railway bolts zoo tib yam yog 8.8 qib zoo tib yam hom nrog torque 350-400N·m thiab tus nqi qis dua. High-cov tsheb ciav hlau ceev cov phaj siab yog siab- cov khoom siv roj hmab elastic nrog dynamic thiab zoo li qub stiffness piv Tsawg dua los yog sib npaug rau 2.0, zoo heev poob siab thiab txo suab nrov; zoo tib yam railway puag daim hlau yog roj hmab + steel phaj sib xyaw hom nrog siab tawv thiab muaj zog hnav tsis kam. High-speed railway siab daim hlau muaj elastic buffering, arc qhov tsim los tiv thaiv khawb rails; zoo tib yam railway siab daim hlau yog rigid ncaj daim hlau, tsom rau cov ntshiab txwv muaj nuj nqi. Tag nrho cov khoom siv ntawm high-speed railway system yog rwb thaiv tsev, thaum zoo tib yam railway system tsis muaj rwb thaiv tsev yuav tsum tau thiab yooj yim accessory qauv.
Dab tsi yog qhov tseem ceeb ntawm kev tsim kho ntawm fastening system installation?
Ua ntej txhim kho lub fastening system, ua ntej ntxuav qhov chaw sib cuag ntawm cov neeg pw tsaug zog thiab cov ntsia hlau, tshem tawm cov xeb thiab cov khib nyiab kom cov khoom siv haum tsis muaj qhov khoob, tso lub hauv paus zoo rau kev teeb tsa. Ua ntej tso rau hauv qab -rail puag phaj thiab qhov chaw nruab nrab, tom qab ntawd tso lub tsheb ciav hlau kom ntsuas qhov ntsuas, xyuas kom cov tsheb ciav hlau ncaj nraim tsawg dua lossis sib npaug li 2 hli yam tsis muaj skew thiab offset. Tom qab ntawd nruab elastic strips thiab siab daim hlau, clamp elastic strips rau hauv rail lub taub hau slots, dlhos lub siab phaj slots nrog rail puag los xyuas kom meej accessories yog tag nrho zaum tsis muaj ntug warping. Xov txhawb nqa bolts thiab ua ntej- nruj hauv batch, thawj zawm rau 50% torque, xyuas kom haum thiab tom qab ntawd xauv nrog tag nrho lub zog kom tsis txhob muaj kev ntxhov siab tsis sib xws los ntawm kev xauv ib zaug. Ntxiv cov insulating gaskets raug teeb tsa rau siab - kev tsheb ciav hlau ceev, kev tiv thaiv hluav taws xob raug sim kom ua tau raws li cov qauv tom qab kev teeb tsa, thiab tag nrho cov kev khiav tsheb tuaj yeem tsav tau tsuas yog tom qab dhau kev lees paub.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev saib xyuas txhua hnub ntawm fastening systems?
Lub kaw lus fastening yuav tsum tau tshuaj xyuas lub bolt torque txhua hli, rov ua dua 500-550N·m rau siab- ceev railway bolts thiab 350-400N·m rau cov railway bolts zoo tib yam, ntxiv thiab nruj rau lub sij hawm yog tias lub zog torque attenuates los tiv thaiv kev xoob. Elastic strips yuav tsum tau kuaj xyuas elasticity thiab kev ncaj ncees, tsis muaj deformation, tsis muaj pob txha, tsis poob, hloov nrog cov tshiab ntawm tib tus qauv tam sim yog elasticity attenuates. Txheeb xyuas qhov hnav ntawm lub hauv paus daim hlau, hloov lub sijhawm yog hnav ntau dua lossis sib npaug li 1 hli, tsom rau kev kuaj xyuas cov rwb thaiv tsev siab ntawm - ceev railway puag daim hlau, hloov nrog cov qauv insulated tam sim ntawd yog tias puas. Txheeb xyuas qhov haum ntawm cov phaj siab, tsis hnav, tsis muaj deformation, xyuas kom tsis muaj kev tsheb nqaj hlau sab nraud, nce kev tshuaj xyuas ntau zaus rau kev lag luam thiab mining siab daim hlau los tiv thaiv kev ua haujlwm hnyav. Tsis tu ncua kev tiv thaiv corrosion rau accessories, derust thiab repaint rusty accessories, hloov stainless hlau accessories nyob rau hauv cov ntug dej hiav txwv kom ntev kev pab cuam lub neej.
