Cov khoom siv twg yog qhov ruaj khov tshaj plaws rau rail ntses daim hlau?
High- lub zog alloy steel yog cov khoom siv ruaj khov tshaj plaws rau kev tsheb nqaj hlau ntses daim hlau, muab kev ua kom qaug zog zoo dua, lub zog tensile siab, thiab lub neej ua haujlwm ntev rau hnyav - tsheb ciav hlau. Cov hlau phaj no ua tau zoo dua cov pa roj carbon zoo tib yam los ntawm kev txo cov bolt loosening thiab deformation, ua rau lawv zoo tagnrho rau kev tsheb loj lossis siab - cov kab ceev.
Kev xaiv sab saum toj:High-lub zog alloy steel (kub-kho) muab qhov zoo tshaj plaws durability thiab ntev.
Lwm txoj kev:
- Stainless hlau: Qhov zoo tshaj plaws rau qhov chaw muaj corrosive heev (nrog ntug dej hiav txwv / kev lag luam).
- Composite/Fiberglass: Muaj kev tiv thaiv corrosion zoo heev thiab hluav taws xob rwb thaiv tsev, zoo tagnrho rau kev siv tshwj xeeb.
- Hlau Hlau: Siv nyob rau hauv qee qhov qis - tsheb thauj mus los, tab sis feem ntau tsis tshua muaj zog dua hlau.
Rau siab tshaj plaws durability thiab kev ntseeg siab nyob rau hauv hnyav- daim ntawv thov lub luag hauj lwm, tshwj xeeb tshav kub-kho alloy steel yog xam raws li tus qauv kev lag luam.
Dab tsi yog qhov kev pab cuam lub neej ntawm lub tsheb ciav hlau sib koom ua ke?
Lub neej kev pab cuam ntawm lub tsheb ciav hlau sib koom ua ke feem ntau yog li ntawm 5 mus rau 10 xyoo rau tus qauv, zoo - tuav cov pob qij txha, tab sis nws txawv raws li kev khiav tsheb thiab hom. Insulated rail pob qij txha feem ntau kav 8-15 xyoo, thaum tshwj xeeb lossis siab - cuam tshuam cov pob qij txha tuaj yeem ua tsis tau li ntawm 2 lub lis piam mus rau 2 lub hlis.
Cov ntsiab lus tseem ceeb cuam tshuam rau lub neej kev pab cuam ntawm kev tsheb ciav hlau sib koom ua ke muaj xws li:
- Hom sib koom:Cov qauv sib koom ua ke feem ntau siv sijhawm ntev dua li cov pob qij txha insulated, uas suav tias yog qhov txuas tsis muaj zog tshaj plaws thiab muaj lub neej luv dua vim muaj kev cuam tshuam ntau dua.
| Kev faib qeb | Hom Rail Joint | Core txhais / Cov yam ntxwv tseem ceeb |
| Los ntawm Txoj Haujlwm ntawm Txoj Kev | Square Joint | Cov pob qij txha nyob rau hauv parallel rails yog aligned opposite ib leeg. Feem ntau ntawm cov kab ncaj nraim; yooj yim tab sis ua rau muaj kev cuam tshuam ntau dua. |
| Kev sib koom ua ke | Cov pob qij txha ntawm ib txoj kev tsheb ciav hlau yog qhov chaw nruab nrab ntawm - taw tes ntawm txoj kev tsheb ciav hlau uas nyob ib sab. Feem ntau siv rau ntawm cov nkhaus kom txo cov rog thiab txhim kho kev caij tsheb zoo. | |
| Los ntawm txoj hauj lwm ntawm Sleepers | Txhawb Kev Sib Koom | Rail xaus so ncaj qha rau ntawm ib qho "joint sleeper". Minimizes deflection tab sis tsim ib tug nruj, siab -maintenance point. |
| Suspended Joint | Rail kawg yog nyob nruab nrab ntawm ob tug pw tsaug zog. Hom ntau tshaj; muab kev yooj yim tab sis yuav tsum tau saib xyuas ntau zaus. | |
| Choj Joint | Zoo ib yam li raug tshem tawm, tab sis siv lub phaj hlau txuas txuas rau ob sab ntawm qhov sib koom ua ke. Tsis siv dav. | |
| Los ntawm Kev Ua Haujlwm & Kev Siv | Ordinary (bolted) Joint | Standard kev twb kev txuas siv fishplates thiab bolts. Tus nqi- zoo, tso cai rau thermal expansion. |
| Kev sib haum xeeb | Txuas ob txoj hlua ntawm qhov sib txawv / profile. Siv cov phaj tshwj xeeb zoo li tus ntses los xyuas kom muaj kev hloov pauv. | |
| Conductive Joint | Ua kom muaj hluav taws xob txuas ntxiv ntawm cov kab tsheb ciav hlau rau traction tam sim no thiab cov teeb liab, siv cov khoom siv hluav taws xob. | |
| Insulated Joint (IRJ) | Hluav taws xob cais cov rail seem rau cov teeb liab. Siv cov ntaub ntawv insulating ntawm cov ntsia hlau thiab daim hlau. | |
| Welded Joint | Rail xaus yog fused ua ke (xws li, thermite welding). Tsim Nruam Welded Rail (CWR) rau kev sib tw, muaj zog dua. | |
| Frozen Joint | Ib qho mob uas nruj los yog corroded fishplates tiv thaiv thermal expansion/contraction, ua rau muaj kev ntxhov siab. | |
| Expansion Joint (REJ) | Tso cai tswj cov kev tsheb ciav hlau ntev (piv txwv li, ntawm cov txuas hniav) kom tiv thaiv buckling lossis tawg vim qhov kub hloov pauv. |
- Kev tu:Kev tu kom zoo, xws li zawm ntses bolts, tuaj yeem txuas lub neej ntawm kev sib koom ua ke, thaum tsis muaj kev saib xyuas ua rau ua tsis tiav ntxov.
- Cov xwm txheej ua haujlwm:Cov tsheb loj ntim thiab qhov hnyav hnyav nce hnav, txo lub neej ntawm cov pob qij txha.
- Khoom siv thiab tsim:Siab - lub zog steel, zoo li 42CrMo, nrog kev kho cua sov kom zoo, tuaj yeem txhim kho hnav thiab qaug zog.
Insulated rail pob qij txha feem ntau yuav tsum tau hloov ntawm tus nqi 10 zaug sai dua li txoj kev tsheb ciav hlau nws tus kheej, feem ntau kav ntev li 12-18 lub hlis hauv qee daim ntawv thov. Kev cuam tshuam cov pob qij txha, uas txuas cov hlua ntawm ntau qhov sib txawv, tshwj xeeb yog qhov tsis zoo thiab yuav tsum tau kuaj xyuas ntau zaus.
