NCO RAU KEV SIB THAM sib tshuam
- Dab tsi yog cov lus uas tau tso cai rau kev sib tw ntev ntawm cov neeg foob thiab cov ntsia?
Longitudinal gap (along the rail length) must be ≤0.3mm, measured with a feeler gauge at both ends of the fishplate. Excessive gap (>0.5mm) ua rau muaj kev cuam tshuam loads thaum cov tsheb ciav hlau dhau mus, doubling tus nqi ntawm loosening ntawm bolts bolts. Ua kom ze haum ntawm kev ciav hlau xaus thiab foob pob thaum lub sijhawm teeb tsa; Siv 0.1-0.2mm nyias nyias cov nplooj ntawv ntawm tsheb nqaj hlau xaus yog tias tsim nyog. Cov khoob khoob khoob khoob khoob khoob khoob khoob yuav tsum yog 0.1mm me dua li cov rog ncaj nraim vim muaj ntau dua cov rog tom qab.
- Yuav ua li cas yog qhov yuav tsum tau ua rau qhov sib txawv tom qab nruab nrab ntawm milegplates thiab tsheb nqaj hlau?
Cov kis rau yav tom ntej (ntawm kev tsheb ciav hlau sab thiab cov neeg sau se) yuav tsum muaj tsawg dua lossis sib npaug nrog 0.5 hli, sib txawv tsawg dua lossis muaj sib npaug rau 0.2 hli. Rau ntau qhov khoob, hloov nrog cov tuab tuab kho kom haum shims (0.3 hli lossis 0.5 hli); Shims yuav tsum yog 65mn steel, tib lub zog ua npauj npaim. Txheeb xyuas nrog 0.5mm kev xav haum tom qab kev teeb tsa; Kev nkag siab tob tob yuav tsum tsis pub tshaj 20mmm, txwv tsis pub rov {{9} kho.
- Puas sib txuas qhov sib txawv sib txawv rau ntau hom neeg foob?
Longitudinal Gap rau 60kg / m kev tsheb nqaj mem hlau yog stricter (tsawg dua los yog sib npaug rau 0.2 hli) vim muaj kev thauj khoom siab; 50kg / m kev tsheb nqaj mem ntses tuaj yeem so kom tsawg dua lossis sib npaug rau 0.4 hli. Cov neeg foob pob hluav taws yuav tsum muaj kev sib pab sib kis tau ntxiv, nrog rau 0.3mm los tiv thaiv kev rwb thaiv tsev rwb tawm tsam ntau dua los yog sib luag rau 10⁸ω). Cov Neeg Sib Tw Tshwj Xeeb Cov Neeg Tsis Txaus Siab 0.1mm loj sib txawv vim muaj cov qauv nyuaj tab sis yuav tsum ua kom muaj kev sib luag.
- Li cas los ntsuas kev sib txuas tsis sib txuas khoob khoob khoob khoob thaum nruab?
Siv cov txheej txheem ntawm cov kev xav ntawm gauges (0.02 - 1mm). Rau cov khoob khoob khoob khoob khoob, coj 3 kev ntsuas ntawm ob qho kawg ntawm tus neeg foob thiab sau qhov siab tshaj plaws; Rau tom qab khoob khoob, siv 2 kev ntsuas ntawm txhua sab ntawm kev tsheb nqaj hlau thiab nruab nrab. Tshem cov xeb thiab impurities los ntawm kev sib chwv nto ua ntej ntsuas kom tsis txhob nyeem yuam kev. Kev kub ceev-ceev cov tsheb ciav hlau xav tau cov tub sab gapital nrog 0.01Mm qhov tseeb, sau txhua tus nqi sib txawv rau kev ua haujlwm archiving.
- Cov teeb meem dab tsi ua rau cov neeg sib tw ua rau muaj ntau qhov sib tw ua rau?
Cov neeg sau ntawv loj ntev dhau los ua rau lwm tus neeg sib txawv ua ke, ua rau muaj kev phem ua ntej ntawm 30% {} 40% thiab yooj yim ua rau tawg ncig lub qhov. Kev sib tw tom qab ntev dhau ntawm cov kev tsheb ciav hlau tom qab Ntev -}}}}}}}}}}}}}}} dua rail kawg hnav, kev sib sau "kev hnav ris tsho" hnav; Cov ntsia yuav tsum tau hloov thaum qhov tob tshaj 2 hli.
