Tus qauv hom ntawm lub siab phaj yuav tsum sib xws nrog cov tsheb ciav hlau txhim kho
Dab tsi yog cov qauv kev ua yeeb yam zoo tshaj plaws ntawm nias daim hlau? Lub tshuab ntxhua khaub ncaws twg yog lawv haum rau?
Cov qauv kev sib tw ntawm cov nias cov phiaj xwm suav nrog nuv {{0} {{- hom, thiab elastic nias daim hlau. Nqe lauj -}} Hom nias cov qauv muaj kev koom tes nrog kev sib koom tes thiab nruab nrab ntawm dog dig kev tsheb ciav hlau thiab cov kab kev tsheb. Groove {{}}} Hom nias daim hlau tau nruab nrog daim npav nrawm, siv rau kev sib tw me me hauv nruab nrab, thiab hnyav} {9} haul railways. Eccentric - Hom nias cov phiaj, siv rau kev hloov pauv nrawm nrawm ntawm eccentric kev teeb tsa thiab roob railways, pab txhawb kev kho kom haum. Elastic nias daim hlau tau tsim - hauv elasticity, siv rau kev sib xyaw ua ke cov kab nrawm dua xws li kev tsheb nqaj hlau xws li kev tsheb nqaj hlau loj thiab trams. Nias daim hlau ntawm cov qauv sib txawv yuav tsum tau sib phim nrog cov tshuab ntxhua khaub ncaws ua kom ntseeg tau cov nyhuv kom ntseeg tau.
Cov khoom xaiv ntawm nias daim phiaj cuam tshuam rau kev ruaj ntseg ntawm kev sib tw ntawm kev sib tw?
Cov khoom siv lub zog ntawm nias daim hlau ncaj qha txiav txim siab ruaj khov, thiab cov khoom siv uas muaj xws li cov hlau zoo li qub, thiab hlau stainless. Cov phiaj xwm carbon steel nias daim hlau tau them tus nqi tsawg dua lossis muaj kev sib luag nrog ntau dua lossis sib npaug ntawm cov khoom lag luam me me, nrog kev kho kom ruaj khov ruaj khov thiab kev sib tham luv luv. Siab - Lub zog alloyy steel nias daim hlau muaj qhov loj tshaj, haum rau kev sib tw loj dua lossis muaj zog} ceev {{{haul lra. Stainless Hlau Nias cov paib muaj cov muaj zog corrosion, tsis yooj yim sua kom xeb thiab cov ntug kev tsheb hluav taws xob thiab cov kab ntug hiav txwv. Cov tawv ntawm cov khoom kuj cuam tshuam rau kev ruaj khov; Tsis txaus ua nruj yuav ua rau mob pob txha ntawm lub phaj nias. Allolo steel muaj manganese, silicon, thiab lwm cov ntsiab tau txhim kho kev nruj thiab zam kev tawg. Siab -}}} Cov khoom siv nias tau meej tuaj yeem ua kom paub tseeb tias txoj kev tsheb ciav hlau tsis muaj teeb meem thaum lub sijhawm ntev} 14 14}} ua haujlwm ruaj khov.
Yuav ua li cas yog cov qauv tsim qauv tshwj xeeb yuav tsum tau siv rau nias cov paib hauv hnyav - haul kab?
Nias daim hlau rau hnyav - haul cov kab yuav tsum tau ua kom muaj zog loj heev, thiab cov qauv tsim tau los txhim kho kev txhim kho kev quab yuam thiab deformation tiv taus. Cov phaj nias tau txais kev tsim tuab, thiab cov phaj tuab yog 20% {}}}}}} thicker tshaj li txhim kho lub zog thiab tsis txhob muaj kev ntxhov siab. Hu rau ib feem ntawm cov phaj nias Adjected ARC tsim, nce ze rau ntawm kev tsheb nqaj hlau, thiab tiv thaiv kev ntxhov siab ntau hauv nroog. Ib ob npaug - bolt kho qauv yog saws zog ntxiv los ntawm ntau dua 50% tiv thaiv cov raj laum ib zaug los ntawm kev xoob, thiab ua kom cov tsheb ciav hlau tsis cuam tshuam. Hauv qab ntawm lub phaj nias tau nruab nrog anti {{11 {}}}}}}}} Kev txhuam hniav ntev, thiab txhim kho kev ruaj ntseg ruaj khov. Qee qhov hnyav -} haul nias cov phiaj, nrog cov qauv forging sib xyaw ua ke, yoog kom hnyav nrog ntau dua 35t.
Dab tsi yog qhov sib txawv hauv nias phaj xaiv ntawm cov kab nkhaus thiab kab ncaj?
Txoj kev tsheb nqaj hlau ntawm cov kab nkhaus yog raug rau cov paib loj, yog li nias cov phiaj xwm tom qab Kev sib tw ntawm cov kab ncaj yog tsuas yog raug kom ntev nro, thiab yooj yim nuv {} hom thiab elastic nias daim hlau tuaj yeem raug xaiv kom tau raws li kev txhim kho ntev ntev. Lub zog clamping ntawm nias daim paib xav tau 20% {}}}}}} 30% siab dua li clamping quab yuam loj dua los yog sib npaug rau 12kn. Rau me - lub vojvoog curves (<800m), kho tau cov phiaj xwm kho mob ECEXE yuav tsum raug xaiv rau cov paib loj loj rau cov neeg loj loj. Lub zog clamping ntawm nias daim hlau rau cov kab ncaj yuav tsum txo qhov kev ntxhov siab ntxiv rau kev txhim kho cov qauv thiab clamping quab yuam.
Yuav ua li cas phim cov ntsuas seem ntawm nias cov paib nrog cov qauv kev sib tw?
Qhov ntev ntawm lub phaj nias xav tau kom phim cov ciav hlau dav dav ntawm txoj kev tsheb nqaj hlau; lub teeb tsheb ciav hlau muaj lub taub hau tsheb nqaj hlau nqaim (50-60mm), yoog kom luv nias daim hlau nrog ib ntev ntawm 80-100mm; Hnyav rail muaj lub taub hau dav hlau (70-80mm), adapting mus ntev nias daim hlau nrog ib ntev ntawm 100-120mm. Lub qhov siab tsim ntawm lub qhov nias lub phaj yuav tsum ua kom haum rau cov haum nrog cov ciav hlau; Qhov siab dhau yuav ua rau kev kho kom zoo dua, thiab qis dhau yuav cuam tshuam kev sib tw nthuav dav thiab kev cog lus, feem ntau yog qhov siab yog tswj tau ntawm 20-30mm. Txoj hauj lwm ntawm cov ntsia liaj qhov rooj qhov ntawm cov phaj nias yuav tsum sib haum rau tias ntawm cov ntses phaj thiab lub pob hluav taws xob kom tsis txhob muaj teeb meem ntawm 80-120mm kom ntseeg tau kev hloov kho. Cov kev sib tw txawv teb chaws xws li Uic60 thiab 136re muaj cov phiaj hlau sib txawv ntawm GB, yog li cov phiaj xwm sib txawv yog cov kev sib tw ua ke rau cov ciav hlau dav thiab tuab. Thaum kev yoog, tus taub hau tsheb dav dav thiab qhov siab ntawm txoj kev tsheb ciav hlau yuav tsum kuaj xyuas kom meej cov kev teeb tsa raug thiab kho tau zoo ntawm lub phaj nias.
