Fastener Composition
●WJ-8 fasteners yog tsim los ntawm kauv spikes, flat washers, caij nplooj ntoos hlav tuav, insulating gauge blocks, gauge baffles, rail pads, hlau pads, elastic pads nyob rau hauv lub hlau pads, thiab embedded tes tsho. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev hloov qhov siab, lawv kuj suav nrog cov tsheb ciav hlau zoo-tuning pads thiab hlau ncoo qhov siab hloov pauv.
● Muaj ob hom kev caij nplooj ntoos hlav, uas yogW1 caij nplooj ntoos hlav bar(inch 14 mm) thiabX2 lub caij nplooj ntoos hlav bar(inch 13 mm). X2 lub caij nplooj ntoos hlav tuav yog siv thaum siv cov hlua khi me me ntawm cov txuas hniav.
● Muaj ob hom gauge baffles, uas yog gauge baffles rau feem dav thiab sib koom gauge baffles rau clamping daim hlau.
●Elastic ncoo nyob rau hauv cov ntaub qhwv hlau muab faib ua ob hom, A thiab B (ob leeg nrog lub thickness ntawm 12 hli). Class A elastic pads yog siv rau siab - kev tsheb ciav hlau ceev uas tseem xav txog kev thauj khoom, thiab Class B elastic pads yog siv rau siab - kev tsheb ciav hlau ceev uas tsuas yog khiav tsheb thauj neeg.
●Spiral spikes muab faib ua ob hom: s2 thiab s3. Thaum lub fastener ntsia tau rau hauv ib txwm lub xeev lossis txoj kev tsheb ciav hlau qhov siab hloov tsis ntau dua 15 hli, s2 hom kauv ntsia hlau yog siv, thiab thaum qhov kev hloov qhov siab siab dua 15 hli, s3 hom kauv ntsia hlau yog siv.
● Ob hom kev tsheb ciav hlau:
① WJ-8A hom fasteners siv Class A elastic pads (zoo li qub stiffness ntawm 35 ± 5kN / mm), uas yog haum rau cov neeg nrog caij nplooj siab kab khiav hauj lwm tej yam kev mob nrog ib tug siab tshaj plaws ceev ntawm 250km / h rau freight thiab cargo;
② WJ-8B hom fasteners siv Class B elastic pads (zoo li qub stiffness ntawm 23 ± 3kN / mm), uas yog haum rau nteg ob-thaiv ballastless lem nrog ib tug siab tshaj plaws ceev ntawm 350km / h rau cov neeg nrog caij nplooj siab kab;
③ WJ-8C hom fasteners siv Class B elastic pads (zoo li qub stiffness ntawm 23 ± 3kN / mm), uas yog haum rau tso CRTS II hom khiav daim hlau nrog ib tug siab tshaj plaws ceev ntawm 350km / h rau cov neeg nrog caij nplooj siab kab.
