Plaub Cheebtsam ntawm lub Fastening System
Txhua qhov elastic fastening system nyob ib ncig ntawm lub tsheb ciav hlau ko taw ua ke plaub ntu. Cov pw tsaug zog, hauv cov ntoo lossis pob zeb, yog lub hauv paus uas nqa lub tsheb ciav hlau thiab tuav nws ntawm qhov ntsuas. Lub elastic rail clip, ua los ntawm lub caij nplooj ntoos hlav steel, siv lub clamping quab yuam, hu ua ntiv taw load, uas tuav lub tsheb ciav hlau thiab tiv thaiv ntsug thiab sab txav. Lub tsheb ciav hlau ncoo, hauv roj hmab lossis yas, zaum hauv qab ntawm txoj kev tsheb ciav hlau thiab nqus cov kev cuam tshuam thiab kev co thaum tiv thaiv cov neeg pw tsaug zog. Lub liner, feem ntau yog nylon, insulates cov clip los ntawm txoj kev tsheb ciav hlau thiab pw tsaug zog kom cov kab hluav taws xob tsis luv luv -circuited, thiab nws kuj coj cov clip ceg.
Yuav ua li cas cov Cheebtsam ua haujlwm ua ke
Clamping: lub elastic clip nias rau ntawm txoj kev tsheb ciav hlau ko taw thiab tsim cov ntiv taw hnyav ntawm feem ntau 8-13 kN nyob ntawm qhov kev tsim qauv.
Kev rho tawm thiab damping: lub ncoo nyob rau hauv txoj kev tsheb ciav hlau absorbs qhov cuam tshuam ntawm txhua lub log hla thiab tiv thaiv tus neeg tsaug zog los ntawm kev qaug zog tawg.
Kev ntsuas thiab kev ruaj ntseg: cov clip, baseplate, lub xub pwg nyom thiab insulator ua ke tuav qhov kev ncua deb ntawm ob txoj hlua, feem ntau 1435 hli ntawm tus qauv ntsuas.
Kev nyab xeeb hluav taws xob: lub insulator tiv thaiv tam sim no los ntawm txoj kev tsheb ciav hlau mus rau hauv lub txaj pw thiab los ntawm cov clip, uas yuav txwv tsis pub cov teeb liab circuits.
Rail Pad Materials thiab Technical Data
Rail pads yog molded los ntawm peb tsev neeg tseem ceeb, txhua tus muaj qhov sib txawv ntawm qhov tawv nqaij, qhov kub thiab txias thiab rwb thaiv tsev. EVA pads siv polyethylene thiab vinyl acetate sib xyaw, feem ntau yog li 80% polyethylene thiab 20% vinyl acetate; HDPE pads yog tawv thiab tawv dua; roj hmab pads muab qhov zoo tshaj plaws qis - kub elasticity thiab damping.
| Parameter | EVA pad | HDPE hnab |
|---|---|---|
| Qhov ceev (g / cm3) | 0.95-0.98 | 0.95-0.98 |
| Tensile zog (MPa) | Ntau dua lossis sib npaug rau 15, feem ntau 16 | Ntau dua lossis sib npaug li 19 |
| Elongation (%) | Ntau dua lossis sib npaug rau 500, ib txwm 550 | Ntau dua lossis sib npaug rau 80, feem ntau 150 |
| Melting point (zeeg) | 170-190 | 126-135 |
| Rwb thaiv tsev tsis kam (Ω) | Loj dua los yog sib npaug rau 1 × 10 ^ 10, raug 5 × 10 ^ 10 | Loj dua los yog sib npaug rau 1 × 10 ^ 10, feem ntau 3.5 × 10 ^ 10 |
| Hardness (Shore A) | Ntau dua lossis sib npaug rau 90, feem ntau 92 | Ntau dua lossis sib npaug li 98 |
| Parameter | Rubber rail ncoo |
|---|---|
| Kev nruj (kN / mm) | 90-130 |
| Hardness (Shore A) | 72-80 |
| Hluav taws xob tsis kam (Ω) | Ntau dua lossis sib npaug rau 10^6 |
| Tensile zog ua ntej kev laus (MPa) | Ntau dua lossis sib npaug rau 12.5 |
| Elongation ua ntej aging (%) | Ntau dua lossis sib npaug li 250 |
Xaiv txoj kev sib xyaw ua ke
Sib piv cov ntiv taw hneev taw thiab tuab rau qhov kev teeb tsa fastening; pads yog tsim rau rail profiles xws li UIC54, UIC60, BS80A thiab BS100A, nrog grooves los yog tiaj nto raws li tau teev tseg.
Xaiv qhov sib xyaw los ntawm huab cua: roj hmab rau qis -kub elasticity, EVA thiab HDPE qhov twg huab cua ruaj khov thiab nruj yog qhov tseem ceeb.
Txheeb xyuas qhov kev xav tau ntawm rwb thaiv tsev ntawm lub teeb liab system; pads ntawm cov kab hluav taws xob yuav tsum tuav cov txheej txheem rwb thaiv tsev tiv thaiv tag nrho lawv lub neej kev pabcuam.
Paub meej tias tus qauv clip tiv thaiv lub ncoo thiab lub xub pwg geometry; cov ntiv taw load thiab lub ncoo txhav yog tsim los ua ke, thiab hloov ib qho tsis muaj lwm yam hloov tus cwj pwm dynamic ntawm txoj kev khiav.
Thov kos duab kos duab ua ntej xaj; pads tuaj yeem tsim tsis muaj grooves, nrog ib leeg lossis ntau qhov zawj, thiab nrog qhov ntau thiab tsawg kom haum rau cov neeg siv khoom fastening system.
Kev Ntseeg Tsis Zoo
Ib qho kev xav tsis tu ncua yog tias qhov clip ua txhua yam haujlwm thiab lub ncoo tsuas yog txo cov suab nrov. Qhov tseeb, lub ncoo tseem tswj xyuas qhov nruj ntawm txoj kev khiav, thiab nws qhov xwm txheej ncaj qha hloov cov ntiv taw hnyav dhau los ntawm qhov clip. Lwm qhov kev xav tsis zoo yog tias cov ntaub qhwv tawv tawv yog ib txwm zoo dua; ib qho dhau - cov ntaub qhwv tawv tawv hloov mus rau hauv lub txaj pw thiab txo qhov damping qhov system tau tsim los rau. Thaum kawg, lub liner yog qee zaum kho raws li qhov kev xaiv; tsis muaj nws, qhov clip tuaj yeem luv luv -circuit Circuit Court thiab clip ceg poob nws cov kev taw qhia sab.
Cov lus nug nquag
Q: Lub luag haujlwm ntawm elastic rail clip yog dab tsi?A: Nws siv thiab tswj cov ntiv taw load uas clamps lub tsheb ciav hlau ko taw mus rau lub sleeper, resisting ntsug, lateral thiab longitudinal txav ntawm txoj kev tsheb ciav hlau nyob rau hauv lub tsheb.
Q: Dab tsi yog qhov txawv ntawm lub tsheb ciav hlau thiab lub liner?A: Lub ncoo zaum hauv qab txoj kev tsheb ciav hlau thiab cushions cuam tshuam; lub liner zaum ntawm ib sab ntawm txoj kev tsheb ciav hlau, sib cais cov clip los ntawm txoj kev tsheb ciav hlau thiab muab hluav taws xob rwb thaiv tsev thiab kev taw qhia sab nraud.
Q: Vim li cas EVA pads siv los ntawm cov ntaub qhwv roj hmab?A: EVA muaj cov huab cua ruaj khov thiab kub ntau yam nrog tus nqi qis; roj hmab yog qhov xav tau qhov siab tshaj plaws damping thiab qis -kub elasticity yuav tsum tau.
Q: Cov ntaub qhwv puas tuaj yeem tsim nrog cov grooves?A: Yog. Pads muaj nyob dawb los yog zawj, nrog cov qauv groove sib phim rau kev tsim cov txheej txheem fastening; daim duab yuav tsum hais qhov zawj layout thiab lub thickness kam rau ua.
Q: Dab tsi rail profiles yog rail pads feem ntau ua rau?A: Cov profiles muaj xws li UIC54, UIC60, BS80A thiab BS100A, ntxiv rau 43-75 kg / m profiles; kev cai qhov ntau thiab tsawg yog tsim rau cov neeg siv khoom kos duab.
