Daim teb Railway

Txoj kev tsheb ciav hlau yog ib qho tseem ceeb tshaj plaws inventions thiab txhais tau tias ntawm kev thauj mus los ntawm noob neej. Tau ntau pua xyoo, noob neej tau txuas ntxiv txhim kho nws cov thev naus laus zis, thiab technology ntawm railways thiab locomotives tseem tsis tau mus txog nws lub ncov.

Hnub no, railways thoob ntiaj teb muaj kev thauj mus los ntau dua li yav dhau los, thiab cov kev xav tau muab tso rau cov tuam txhab lag luam thiab lawv cov neeg muag khoom hloov pauv tas li. Cov khoom lag luam luv luv thiab thev naus laus zis tshiab, kev siv cov tshiab, siab dua, sib dua, ntau zog-txuag thiab ib puag ncig tus phooj ywg cov ntaub ntawv, thiab txawm tias qhov kev hloov pauv ntawm kev ua haujlwm yuav tsum tau hloov kho tshiab thiab hloov pauv mus tas li.

Hlau Xov Ntxig, tus kheej tapping xov insert thiab qhov tseem ceeb locking insert yog dav siv nyob rau hauv railways thiab locomotives li tshiab thiab tshiab fastening technologies. High-speed railways tau tsim tshwj xeeb hauv peb lub teb chaws, thiab high-ceev EMUs yog ua hauj lwm nyob rau hauv coob ntawm tag nrho cov loj railway kab thoob plaws lub teb chaws thiab xa mus rau ntau lub teb chaws. Aluminium alloy tau dhau los ua cov khoom tseem ceeb ntawm cov tsheb thauj khoom vim nws lub teeb yuag thiab zoo sealing zog. Txawm li cas los, qhov muag ntawm cov ntaub ntawv aluminium alloy ua rau tsis muaj zog shear tsis kam nyob rau hauv threaded sib txuas. Kev ua haujlwm ncaj qha ntawm cov xov ntawm cov khoom siv hauv paus tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb ntawm kev tsheb ciav hlau sib dhos thiab kev ua haujlwm. Aluminium alloys yuav tsum tau siv cov xov sheaths los xyuas kom meej qhov ruaj khov thiab kev ntseeg siab ntawm kev sib txuas.

Nyob rau hauv ntau yam ntawm domestic EMUs, threaded sheaths yog siv nyob rau hauv ntau yam threaded kev twb kev txuas lug xws li tsheb interiors, sab nrauv suspensions, thiab under-car hoisting. Cov hom tseem ceeb muaj xws li xaim xov inserts, Yus tus kheej tis xov ntxig, thiab key locking thread inserts. Lub CRH1 EMU muaj lub cev stainless hlau thiab tsis tas yuav tsum tau siv cov threaded sheaths; CRH2 EMU feem ntau siv steel hlau threaded inserts; CRH3 EMU tsuas yog siv tus kheej tapping threaded inserts, thiab kuj tseem siv tau rau qee qhov kev sib txuas ntawm cov yeeb nkab loj. Hlau xov inserts yog siv nyob rau hauv qhov chaw; key xauv xov inserts yog siv nyob rau hauv CRH5 EMUs.
