Track Fastening System: Tag Nrho Kev Sib Tw thiab Kev Sib Tw
Dab tsi yog qhov tseem ceeb ua tiav kev faib tawm ntawm kev khiav ceev thiab cov hom kev siv tau?
Cov txheej txheem fastening tau muab faib ua plaub yam ua tiav: siab - ceev railway elastic fastening system, zoo tib yam railway rigid fastening system, industrial thiab mining hnyav-duty fastening system thiab txawv teb chaws tus qauv txhawb fastening system, adapting rau txawv scenarios. Lub siab - kev tsheb ciav hlau nrawm nrawm nrawm suav nrog W2 / X3 elastic strips, 10.9 qib insulating bolts thiab roj hmab puag daim hlau, haum rau siab - ceev railway ballastless lem nrog ob qho tib si xauv thiab kev poob siab ua haujlwm. Txoj kev tsheb ciav hlau zoo tib yam 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 thiab ruaj khov. 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- cov dej num nrog kev cuam tshuam thiab tiv thaiv - loosening. Txawv txawv tus qauv fastening tshuab tau muab faib ua UIC / BS / AREMA qauv, raws li kev yoog raws cov qauv txawv teb chaws, ua raws li cov qauv kev txhawb nqa thoob ntiaj teb.
Dab tsi yog cov ntsiab lus tseem ceeb sib piv thiab xaiv cov ntsiab lus ntawm fastening system accessory ua ke?
Kev sib xyaw ua ke ntawm cov khoom siv fastening yuav tsum ua raws li peb lub hauv paus ntsiab lus ntawm kev sib tw tsheb ciav hlau, kev hloov kho cov kab thiab cov qauv kev sib koom ua ke, tshem tawm tus ntoo khaub lig- specification thiab cross- qauv sib xyaw. Lub elastic strip qauv yuav tsum sib phim lub taub hau loj ntawm txoj kev tsheb ciav hlau, lub zog bolt yog synchronized nrog elastic strip locking quab yuam, thiab lub hauv paus phaj thickness yog yoog raws li qhov kev thov kev sib hais haum. High- cov kab tsheb ciav hlau ceev nyiam cov tshuab ua kom tiav, cov kev tsheb ciav hlau zoo tib yam xaiv cov kab ke ua tiav, kev lag luam thiab mining hnyav-lub luag haujlwm xaiv thickened siab- lub zog ua tiav, thiab xaiv ntawm kev thov yam tsis muaj qhov muag tsis pom kev kho dua tshiab. Cov khoom siv sib xyaw ua ke yuav tsum xav txog qhov yuav tsum tau muaj rwb thaiv tsev, siab - kev tsheb ciav hlau ceev ntxiv cov khoom siv rwb thaiv tsev, kev tsheb ciav hlau zoo tib yam / kev lag luam thiab cov mining tuaj yeem txuag qhov rwb thaiv tsev, txo nqi thaum lub rooj sib tham ua haujlwm. Kev xaiv yuav tsum xyuas qhov loj me, cov khoom siv thiab lub zog tsis zoo ntawm cov khoom siv ua tiav kom tsis muaj qhov sib txawv hauv kev xauv thiab kev ntxhov siab tom qab ua ke.
Dab tsi yog qhov tseem ceeb ntawm cov khoom siv sib txawv ntawm qhov siab - txoj kev tsheb ciav hlau ceev thiab cov kab tsheb ciav hlau zoo tib yam?
Cov khoom siv tseem ceeb ntawm kev siab - ceev railway fastening system yog elastic strips, insulating bolts, roj hmab elastic puag daim hlau thiab siab -precision siab daim hlau, tag nrho cov khoom siv muaj kev poob siab thiab rwb thaiv tsev ua haujlwm, yoog raws cov kev xav tau ntawm high - kev tsheb ciav hlau ceev. Ordinary railway fastening system yog nruj elastic strips, zoo tib yam bolts, composite nyuaj lub hauv paus daim hlau thiab cov pa siab daim hlau, tsis muaj rwb thaiv tsev thiab poob siab absorbing Cheebtsam, tsom rau yooj yim locking muaj nuj nqi. High -Speed railway bolts yog 10.9 qib insulated siab-lub zog bolts, anti-electrocorrosion thiab siab dua locking torque, zoo tib yam railway bolts yog 8.8 qib zoo tib yam bolts, ntsib yooj yim locking nkaus xwb. High- nrawm railway puag daim hlau yog siab- cov khoom siv roj hmab elastic, dynamic thiab zoo li qub stiffness piv ≤2.0, zoo heev poob siab absorbing nyhuv, zoo tib yam railway puag daim hlau yog cov khoom sib xyaw, siab tawv thiab muaj zog hnav tsis kam. High-Speed railway elastic strips yog ob chav elastic strip tsim nrog buckling quab yuam ≥10kN, zoo tib yam railway yog ib tug elastic strip tsim nrog buckling quab yuam ≥6kN, locking quab yuam yog teem rau thov.
Dab tsi yog cov txheej txheem tseem ceeb thiab kev tsim kho tshwj xeeb rau kev ua tiav ntawm cov txheej txheem fastening?
Rau fastening system installation, ua ntej ntxuav lub sleeper installation nto, tso rau hauv qab -rail base phaj raws li txoj hauj lwm rail kom paub tseeb tias lub hauv paus phaj yog nruab nrab tsis offset, nteg lub hauv paus rau tom ntej installation. Tom qab ntawd muab lub tsheb ciav hlau rau ntawm lub hauv paus phaj, calibrate lub ntsuas thiab txoj kab ncaj nraim, tso lub elastic strip thiab siab phaj tom qab paub meej tias tsis muaj tsheb ciav hlau skew, thiab lub qhov yog txuas nrog lub hauv paus kev tsheb nqaj hlau. Tom qab ntawd xov cov kev txhawb nqa bolts, ua ntej-ntxo mus rau 50% ntawm tus qauv torque ua ntej, xyuas cov khoom siv haum thiab tom qab ntawd xauv nrog lub zog tag nrho kom tsis txhob muaj kev ntxhov siab tsis sib xws los ntawm kev xauv ib zaug. Ntxiv insulating gaskets yuav tsum tau muab ntsia rau siab - ceev railway system installation, thiab cov rwb thaiv tsev tiv thaiv yuav tsum tau kuaj ≥5 × 10^6Ω tom qab kev teeb tsa los xyuas kom meej rwb thaiv tsev mus txog tus qauv yam tsis muaj to. Tom qab kev teeb tsa, txheeb xyuas qhov taw tes los ntawm qhov taw tes tias tsis muaj ntug kev sib tsoo ntawm cov khoom siv, tsis muaj qhov xoob ntawm cov ntsia hlau, tsis muaj kev hloov ntawm cov ntsia hlau, thiab qhov yuam kev ntawm tag nrho cov khiav yog ≤2mm.
Yuav ua li cas hloov cov hauv paus ntsiab lus thiab kev txhawb nqa rau cov khoom siv poob hauv kev siv lub kaw lus fastening yog dab tsi?
Kev hloov cov khoom siv fastening puas yuav tsum ua raws li cov hauv paus ntsiab lus ntawm tib tus qauv thiab cov lus qhia tshwj xeeb, kev hloov ua tiav hauv zos, tsis muaj tus ntoo khaub lig- hloov tus qauv kom ntseeg tau tias tag nrho cov kev ua tau zoo ntawm lub kaw lus tseem tsis hloov. Deformed / tawg elastic strips yuav tsum tau hloov nrog tib cov qauv elastic strips, cov qauv sib txawv tsis tuaj yeem siv los hloov kom tsis txhob muaj zog buckling tsis txaus ua rau kev tsheb ciav hlau loosening. zawv zawg/rusted bolts yuav tsum tau hloov nrog bolts ntawm tib lub zog thiab specification, siab - ceev railway insulating bolts tsis tuaj yeem hloov nrog cov bolts zoo tib yam los tiv thaiv kev rwb thaiv tsev tsis ua hauj lwm thiab kev kaw lub zog txo. Lub hauv paus daim hlau uas hnav tshaj 1 hli yuav tsum tau hloov nyob rau hauv lub sij hawm, roj hmab puag daim hlau nrog tib hom elastic, hnav-cov ntaub ntawv uas muaj cov tuab tuab los xyuas kom muaj kev poob siab thiab kev coj tus cwj pwm. Kev hloov pauv hauv zos tau tso cai rau kev puas tsuaj ib leeg, thiab tag nrho cov seem ua tiav yuav tsum tau hloov pauv rau ntau yam kev puas tsuaj, rov- xauv raws li tus qauv torque tom qab hloov, thiab muab tso rau hauv tsuas yog siv yog tias tsis muaj qhov txawv txav hauv kev sim ua haujlwm.
