Rail Clip Clamping Pressure thiab Track Compatibility Standards
Vim li cas ho high clamping force rail clips xaiv rau siab - kev tsheb ciav hlau ceev?
High - tsheb ciav hlau ceev khiav ntawm kev kub ceev, tsim lub log loj- kev tsheb ciav hlau cuam tshuam thiab kev co. High clamping force rail clips tuaj yeem ua kom zoo sib xws ntawm cov ntsia hlau thiab cov neeg pw tsaug zog thiab tsis txhob muaj kev hloov tsheb. Lub zog clamping siab tuaj yeem muab qhov ntev txaus los tiv thaiv cov kab seamless los ntawm telescopic deformation thaum kub hloov. Kev ruaj ntseg clamping quab yuam ntawm kev tsheb ciav hlau clips tuaj yeem txo kev co thiab lub suab nrov los ntawm lub log tsis zoo- kev sib tiv tauj thiab txhim kho kev tsav tsheb du. Nyob rau tib lub sij hawm, siab clamping quab yuam rail clips muaj ib tug ruaj khov qauv tsim thiab muaj zog qaug zog tsis kam, uas yuav hloov tau mus rau lub siab -frequency stress ntawm high- kab ceev. Tsis tas li ntawd, nws tuaj yeem tiv taus qhov cuam tshuam ntawm kev thauj khoom sab nraud, ua kom muaj kev ruaj ntseg ntawm kev taug qab geometric qhov ntev, thiab txo qhov kev pheej hmoo ntawm kev nyab xeeb.
Dab tsi kab scenarios yog me me kuj rail clips haum rau?
Cov kab hluav taws xob me me (xws li X2 hom) yog qhov tsim nyog rau cov kab uas cov tsheb ciav hlau xav tau ib qho kev ncua ntev ntawm cov neeg pw tsaug zog, xws li ntev - txuas txuas, qhov nkag thiab tawm thiab lwm qhov chaw uas muaj kev kub ntxhov siab. Nws lub zog clamping ntawm txog 6kN tuaj yeem sib npaug ntawm txoj kab kev tiv thaiv thiab kev nthuav dav kev tsheb nqaj hlau, kom tsis txhob muaj kev ntxhov siab ntau dhau los ntawm kev hloov pauv kub. Nyob rau hauv kev tso cov kab seamless, me me tsis kam rail clips yuav txo tau cov tsub zuj zuj ntawm longitudinal kev nyuaj siab nyob rau hauv rails thiab txo txoj kev pheej hmoo ntawm rail breakage. Hom kev tsheb ciav hlau no tseem tsim nyog rau cov ntu nrog cov txheej txheem geological nyuaj thiab ua tau txoj kab loj loj, uas tuaj yeem hloov kho me me deformations. Nyob rau tib lub sijhawm, nws qhov kev teeb tsa thiab kev hloov kho tau yooj yim dua, thiab tus nqi saib xyuas qis dua, ua rau nws tsim nyog siv rau hauv cov kab hauv kev ua haujlwm tshwj xeeb.
Vim li cas qhov kev qaug zog ntawm kev tsheb ciav hlau clips yog qhov taw qhia tseem ceeb?
Thaum lub sij hawm lub tsheb ciav hlau ua haujlwm, rail clips raug siab - zaus vibration thiab load cycles ntev. Kev ua haujlwm qaug zog tsis txaus yuav ua rau cov kab nrib pleb thiab tawg ntawm cov tsheb ciav hlau, ua rau cov tsheb ciav hlau loosening. Kev ua tau zoo qaug zog tuaj yeem ua kom ntseeg tau tias tom qab ntau tshaj 3 lab lub sijhawm thauj khoom, lub zog clamping attenuation ntawm rail clips tsis pub tshaj 20%, tuav ntev - lub sij hawm fastening nyhuv. Rail clips nrog kev ua haujlwm qaug zog tsis zoo yuav ua rau muaj kev saib xyuas ntau zaus thiab hloov cov nqi, cuam tshuam rau kev ua haujlwm ntawm kab. Kev qaug zog ntawm kev sib tsoo ntawm kev tsheb ciav hlau tuaj yeem ua rau kev tsheb ciav hlau khiav tawm, uas ua rau muaj kev hem thawj rau kev nyab xeeb ntawm kev tsav tsheb, yog li qhov ntsuas no yuav tsum tau tswj nruj me ntsis. Tsis tas li ntawd, kev ua haujlwm qaug zog yog ze ze rau cov khoom siv rail clip thiab cov txheej txheem kho cua sov, uas yog qhov tseem ceeb ntawm cov khoom zoo.
Dab tsi yog qhov sib txawv ntawm clamping quab yuam ntawm Hom II thiab Hom III rail clips thiab lawv cov xwm txheej siv tau?
Hom II rail clips feem ntau yog siv rau 60kg / m rails nrog lub zog clamping txog 40kN / mm, haum rau 200-250km / h kab; Hom III rail clips muaj ntau dua clamping quab yuam thiab ib tug ntau compact qauv, haum rau siab - ceev railways ntawm 350 km / h thiab siab dua. Hom II rail clips muaj qhov nruj me ntsis, ntsuas qhov ceev thiab elasticity, haum rau cov pa ceev railways thiab nruab nrab - cov neeg caij tsheb ceev. Hom III rail clips txais yuav qhov kev tsim kho kom zoo nrog lub caij nplooj ntoos hlav loj dua thiab lub zog qaug zog ntau dua, uas tuaj yeem tiv nrog kev cuam tshuam ntau dua ntawm kev kub siab - tsheb ciav hlau ceev. Hauv hnyav- cov kab tsheb thauj mus los, Hom II rail clips tuaj yeem ua tau raws li qhov yuav tsum tau ua los ntawm kev siv ua ke; Hom III tsom ntau dua rau kev ruaj ntseg hauv cov xwm txheej ceev. Qhov sib txawv tsim ntawm ob yog kom raug raws li qhov ceev thiab thauj khoom ntawm cov kab sib txawv.
Yuav ua li cas los xyuas seb lub clamping quab yuam ntawm rail clips ua tau raws li tus qauv?
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws yog qhov yuav tsum tau siv cov cuab yeej tshwj xeeb siab los ntsuas cov kev ntxhov siab ntawm cov tsheb ciav hlau. Thaum kuaj pom, nws yog ib qho tsim nyog los xyuas kom meej tias lub installation txoj hauj lwm ntawm rail clips yog qhov tseeb thiab haum zoo nrog cov rwb thaiv tsev thaiv, hlau puag daim hlau thiab lwm yam khoom kom tsis txhob muaj kev sib txawv ntawm kev teeb tsa cuam tshuam rau cov txiaj ntsig. Rau cov kab nteg, cov ntaub ntawv tshawb nrhiav dynamic ntawm kev soj ntsuam tsheb tuaj yeem siv los txiav txim ncaj qha seb lub clamping quab yuam ntawm cov tsheb ciav hlau yog qhov ruaj khov. Thaum lub sij hawm soj ntsuam cov qauv tsis tu ncua, cov qauv tsim nyog yuav tsum tau ua kom paub tseeb tias cov qauv yog cov neeg sawv cev, suav nrog cov kab tsheb ciav hlau sib txawv ntawm cov khoom sib txawv thiab lub sijhawm ua haujlwm. Cov txiaj ntsig kev xeem yuav tsum tau muab piv nrog cov qauv tsim. Rail clips nrog qhov sib txawv tshaj ± 10% yuav tsum tau hloov raws sijhawm kom ntseeg tau tias kab kev nyab xeeb.
