Kev xaiv thiab kev ua tau zoo Matching Technology ntawm Elastic Rail Fasteners
Dab tsi yog hom ntawm elastic rail clip fasteners thiab lawv cov xwm txheej hloov tau?
Lub WJ-8A hom fastener txais A-chav kawm elastic puag phaj nrog lub zog zoo li qub ntawm 35 ± 5kN / hli, haum rau cov neeg caij tsheb tshwj xeeb uas suav nrog kev thauj khoom thauj thiab muaj qhov ceev tshaj plaws ntawm 250km / h. WJ-8B hom fastener yog txuam nrog B-chav kawm elastic puag phaj nrog lub zog zoo li qub ntawm 23 ± 3kN / mm, haum rau ballastless lem nrog ob - thaiv cov neeg pw tsaug zog thiab cov neeg caij tsheb siab nrog qhov siab tshaj plaws ntawm 350km / h. Lub WJ-8C hom fastener kuj siv B-chav kawm elastic puag phaj, yoog rau CRTSII hom slabs thiab ua tau raws li qhov yuav tsum tau ua ntawm 350km / h siab{21}} ua haujlwm ceev. Ordinary elastic rail clips yog tsim rau cov pa railways thiab tshwj xeeb kab ntawm factories thiab mines, muab yooj yim clamping quab yuam. Tshwj xeeb elastic rail clips rau hnyav-haul kab yog ua los ntawm high-lub zog cov ntaub ntawv nrog ntau dua clamping quab yuam, uas muaj peev xwm tiv thaiv rov qab cuam tshuam ntawm hnyav-haul tsheb ciav hlau.
Dab tsi yog qhov tseem ceeb ntawm kev ua tau zoo ntawm elastic rail clips? Yuav ua li cas lav lawv?
Cov kev ua tau zoo tseem ceeb ntawm elastic rail clips muaj xws li clamping quab yuam, elasticity, qaug zog lub neej thiab corrosion kuj. Lub clamping quab yuam yuav tsum ua tau raws li cov qauv tsim. Lub clamping quab yuam ntawm elastic rail clips rau cov kab zoo tib yam tsis tsawg tshaj li 10kN los xyuas kom meej tias txoj kev tsheb ciav hlau tsis txav. Lub elasticity Performance index txiav txim siab qhov cuam tshuam ntawm kev poob siab, uas yuav tsum tau sib phim nrog qhov nruj ntawm cov ntaub thaiv kev tsheb ciav hlau kom tsis txhob muaj suab nrov. Lub neej qaug zog yuav tsum tsis muaj kab nrib pleb tom qab ntau lab lub voj voog ntawm kev sim kom ntseeg tau ntev - siv sijhawm ntev. Corrosion tsis kam yog ua tiav los ntawm kev kho saum npoo xws li galvanizing, yoog mus rau corrosive ib puag ncig xws li av noo thiab ntug hiav txwv. Kev ntsuas kev lees paub suav nrog xaiv cov khoom zoo-cov khoom siv caij nplooj ntoos hlav steel zoo, tswj cov txheej txheem kev kho cua sov, thiab ua cov khoom-los ntawm-cov khoom kuaj ua ntej tawm hauv lub hoobkas.
Dab tsi yog qhov yuav tsum tau ua rau qhov sib txuam ntawm elastic rail clip fasteners thiab rail pads?
Qhov nruj ntawm elastic rail clip fasteners thiab rail pads yuav tsum tau tsim kev sib koom tes kom tsis txhob muaj kev vibration ntau dhau los yog tsis txaus clamping quab yuam tshwm sim los ntawm qhov tsis sib haum xeeb. Nyob rau hauv siab - cov kab ceev, qhov elasticity ntawm elastic rail clips yuav tsum tau ua ke nrog qis - nruj rail pads. Lub WJ-8B hom elastic rail clip yog txuam nrog B-chav kawm ncoo nrog 23 ± 3kN / mm kom ua tiav cov txiaj ntsig zoo poob siab. Hnyav- cov kab tsheb yuav tsum tau txhim kho qhov system nruj, ua kom lub zog clamping ntawm elastic rail clips, thiab phim lawv nrog siab - tawv tawv los tiv thaiv kev hloov tsheb. Pa railways tuaj yeem txais qhov nruab nrab nruj ua ke ua ke kom sib npaug ntawm kev poob siab thiab kev teeb tsa tus nqi. Kev sib tw nruj yuav tsum tau txiav txim siab los ntawm kev suav cov kab hluav taws xob los xyuas kom meej tias lub log-rail rog nyob rau hauv qhov tsim nyog thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev ntsuas kev ua haujlwm rau elastic rail clips tom qab kev teeb tsa?
Tom qab kev teeb tsa, nws yog ib qho tsim nyog los ntsuas lub zog clamping ntawm elastic rail clip nrog cov cuab yeej ntsuas tshwj xeeb kom ntseeg tau tias nws tsis qis dua tus nqi tsim, Ntau dua lossis sib npaug rau 10kN rau cov kab zoo tib yam, thiab siab dua rau siab - kab nrawm. Txheeb xyuas qhov haum ntawm qhov elastic rail clip, rail thiab hlau puag phaj, nrog qhov sib txawv tsawg dua los yog sib npaug li 0.5 hli kom tsis txhob muaj zog sib npaug. Saib xyuas lub elastic rail clip rau deformation, tawg thiab lwm yam tsis xws luag kom tsis muaj kev puas tsuaj thaum lub sij hawm installation. Ua kev ntsuam xyuas kev vibration los xyuas qhov elastic rov qab muaj peev xwm ntawm elastic rail clip nyob rau hauv simulated tsheb ciav hlau loads yam tsis tas yuav deformation. Ua raws li niaj zaus- nce kev xeem, ib zaug txhua rau rau lub hlis rau siab - cov kab ceev thiab ib xyoos ib zaug rau cov kab sib xws, thiab hloov cov kev laus los yog ua tsis tiav elastic rail clips raws sijhawm.
Dab tsi yog qhov kev lees paub kev ntsuas rau elastic rail clips nyob rau hauv kev ua haujlwm hnyav?
Nyob rau hauv qhov chaw siab - qhov kub thiab txias, elastic rail clips yuav tsum tau ua los ntawm tshav kub- resistant caij nplooj ntoos hlav steel kom tsis txhob elastic degradation los ntawm qhov kub thiab txias, thiab saum npoo yuav tsum tau coated nrog ib tug siab - kub resistant tiv thaiv - corrosion txheej. Nyob rau hauv qis- qhov kub thiab txias ib puag ncig, elastic rail clips nrog zoo tsis tshua muaj - kub toughness yog nyiam, uas tau dhau los ntawm qis- qhov kub thiab txias kev ntsuam xyuas kom tsis txhob nkig tawg hauv qab -40℃. Nyob rau hauv hnyav-load ua hauj lwm tej yam kev mob, elastic rail clips txais ib tug ntxiv dag zog rau kev kho cua sov txheej txheem los txhim kho yield zog thiab tensile lub zog, nce lub clamping quab yuam cia. Nyob rau hauv ntug dej hiav txwv ntub dej, elastic rail clips yog kho nrog kub-dip galvanizing + passivation los txhim kho ntsev tsuag corrosion kuj. Kev ntsuas kev lees paub kuj suav nrog kev ua kom zoo rau cov qauv tsim ntawm elastic rail clips kom txo tau kev ntxhov siab thiab ua rau lub neej qaug zog.
