Ntshai Nkawm Cov Vaj Tse thiab Kab Adjustation ntawm National txheem Railer Railening tshuab

 

  • Vim li cas thiaj xaiv hom ⅱ hloov hom ⅲ rasteners rau 60kg / h txoj kev sib tw ntawm 120km / h txoj kev sib txawv ntawm 120 {3} kn. 45 kn / hli) ua rau?

Lub hauv paus: Hom ⅱ (30knon / mm) ntais ntawv pob tw, haum tsawg dua los yog sib npaug ntawm 25T, DF4 loadotive). Cov Teeb Meem: Ntaus ⅲ Ua rau 85NP / MM Tag nrho cov tawv nqaij, 120 → 160 → 160% Kev Nyuaj Siab Zoo Li Cas, 5%.

  • Yuav ua li cas daws cov tsis txaus siab rau sab nrauv sab nrauv (tsawg dua lossis sib luag rau $0NK / H Txoj kab xev, thiab dab tsi yog qhov yuav tsum muaj txhav tom qab ua kom zoo?

Kev daws: Hloov EVA ncoo nrog "eva + nylon" ncoo (12mm tuab), tom qab tawv ncauj 18 → 35kn / mm. Qhov yuav tsum tau: ntau dua los yog sib npaug rau 30knon / hli, txwv tsis pub dhau los yog sib npaug rau 0.5 hli. Qhov tshwm sim: 0.4MM kev hloov chaw, 0.2 → 0.12g kev co.

 

Rail Fastener

 

  • Yuav ua li cas hloov hom ⅱ rreakeners rau 75kg / m hnyav {{{} haul rails (30% latle thauj, 12% kev puas tsuaj)?

Hloov kho: ① 60si2mn → 55simnmo caij nplooj ntoos hlav (380 → 320MPA kev ntxhov siab); ② 10 → 14mm ncoo (30 → 25kn / mm txhav); ③ 2 hli thume tho kev thaiv (8 → 10km clamping force). Qhov tshwm sim: 2.5% kev puas tsuaj, haum SS4 locomotive.

  • Cov dab tsi uas tsis muaj kev hloov kho thaum sib txawv ntawm cov nqaj hlau sib txawv (50 / 60/55Kg / m) Txuas phim hom ⅱ fasteners, thiab vim li cas txoj kab sib luag, 10/12 / 141m)?

Cov tsis muaj: ① gauge thaiv (NO.14 / 16/14; ② ncoo tuab. Lub hauv paus: VIM COMPRESSION (1.2 / 1.5 / 1.8mm) kom tig mus rau sab saum toj qhov kev sib cav tsawg dua lossis sib npaug rau 0.3mm.

 

  • Dab tsi yog cov cim tseem ceeb ntawm lub zog txhav txhav txhav txhav txhav {}} clamping quab yuam kev sim, thiab txaus ntshai ntawm kev sim ua tsis tau tejyam (piv txwv li,<6kN clamping force)?​

Indicators: ① 25-50kN/mm vertical stiffness; ② ≥20/30kN/mm lateral stiffness; ③ ≥6/9kN clamping force; ④ ≤10% stiffness decay. Risks: 0.3→1.5mm rail creep, >10 hli sib tshuam sib txawv, 50% hnav siab dua.
