Yuav ua li cas ob Profiles txawv ntawm tus cwj pwm
Load peev.Lub 54E1 qhov siab thiab qhov loj dua muab nws ntau dua ntsug nruj thiab dabtsi yog khoov tsis kam, uas yog vim li cas nws thiaj li tau teev rau mainline thiab hnyav -haul lub luag hauj lwm nrog qag loads nyob rau hauv 20-25 t ntau yam. Lub 50E2, nrog nws qhov siab qis thiab qhov hnyav, haum rau cov khoom sib zog thiab qis qis.
Lub taub hau geometry.Lub 50E2 muaj lub taub hau dav me ntsis (72 hli piv rau 70 hli) txheeb ze rau nws qhov loj, muab qhov dav dav, thaum 54E1 lub taub hau tuab yog tsim rau hnav lub neej nyob rau hauv cov tsheb hnyav. Lub taub hau dav dua, lub taub hau ntawm 50E2 haum rau cov txheej txheem tshwj xeeb uas lub log sib cuag muaj teeb meem ntau dua li ntsug.
Kev sib haum xeeb.Ob qho profile ua haujlwm nrog cov txheej txheem fastening tsim rau 50-54 kg / m ca hauv qab rails, tab sis cov baseplates, pads thiab clips yuav tsum tau sib phim rau qhov tseeb ko taw dav thiab profile duab. 54E1 yog sib xws nrog cov txheej txheem fastening rau 54 kg / m ca hauv qab rail siv nyob rau hauv European tes hauj lwm.
Tej kev siv
| Profile | Tej kev siv |
|---|---|
| 54E1 | Mainlines, hnyav- thauj khoom thauj, siab- cov neeg caij tsheb ceev, tsheb thauj mus los hauv nroog, mining thiab chaw nres nkoj sib txuas |
| 50E2 | Cov kab thib ob, lub teeb- txoj haujlwm taug kev, qis- kev tsheb khiav lag luam spurs, tshwj xeeb layouts |
Hom Steel Qib rau 54E1
54E1 kev tsheb nqaj hlau tuaj yeem muab tau rau hauv ntau qib EN thiab UIC: 900A thiab 1100 (UIC 860 kev xaiv) thiab R260, R350HT thiab lwm yam R- qib qib hauv qab EN 13674-1. R260 muab txog 880 MPa yam tsawg kawg nkaus tensile lub zog nrog hardness nyob rau hauv 260 HB band; R350HT yog lub taub hau-hardened rau 350 HB band nrog txog 1175 MPa yam tsawg kawg nkaus tensile lub zog rau nkhaus thiab hnyav tsheb. Kev xaiv qib, tsis yog qhov profile, teeb tsa lub neej hnav.
Cov lus nug nquag
1. Qhov twg muaj zog dua, 54E1 lossis 50E2?
ua 54e1. Nws qhov loj dua, ntau dua thiab ntau dua ntsug ntsug muab nws ntau dua dabtsi yog khoov thiab muaj peev xwm thauj khoom. Lub 50E2 yog tsim los rau lub luag haujlwm sib zog, tsis yog rau kev hloov ntawm cov kab siab -load.
2. Yuav 50E2 rail hloov 54E1 rail?
Tsis yog rau siab dua - cov kab thauj khoom. Lub 50E2 muaj peev xwm qis dua thiab sib txawv lub taub hau geometry, yog li kev hloov pauv ntawm lub ntsiab lus tseem ceeb yuav xav tau rov qab- txheeb xyuas tag nrho cov qauv tsim, suav nrog kev sib khi thiab cov pob qij txha. Rau lub teeb theem nrab kab nws tuaj yeem txiav txim siab tsuas yog nrog kev kuaj xyuas engineering tag nrho.
3. Puas yog 54E1 rail kim dua?
Ib 'meter', yog: nws siv hlau ntau dua thiab hnyav dua rau kev thauj mus los. Tab sis ntawm txoj kab tseem ceeb nws lub neej kev pab cuam ntev dua thiab muaj peev xwm siab dua feem ntau ua rau nws siv nyiaj ntau dua rau lub neej khiav, uas yog vim li cas lub neej - nqi mus ncig, tsis yog nqi tsev, yuav tsum tsav kev xaiv.
4. Qhov twg yog 50E2 rail feem ntau siv?
Lub teeb- lub luag haujlwm lem, kab thib ob, kev lag luam sab hauv thiab qis- daim ntawv thov kev khiav tsheb uas tsis muaj qhov tseem ceeb ntawm tag nrho. Nws lub taub hau dav kuj haum rau qee qhov tshwj xeeb log profiles.
5. Cov fastenings rau 54E1 thiab 50E2 puas zoo ib yam?
Tsis tau. Lub hauv paus zoo, daim ntawv qhia txog lub ncoo thiab lub rooj zaum yuav tsum sib haum rau txoj kev tsheb ciav hlau ntawm txhua qhov profile. Tshawb xyuas qhov kev teeb tsa fastening tiv thaiv cov duab kos ua ntej xaj, lossis thov kom tiav cov txheej txheem sib tw.
6. Ob qho profile puas tuaj yeem muab tau nrog drilling thiab txiav?
Yog lawm. Ob leeg 54E1 thiab 50E2 tuaj yeem muab rau hauv cov qauv ntev nrog kev txiav, drilling thiab lwm yam machining ib qhov project kos duab, ua ke nrog cov khoom sib txuas.
