Dab tsi yog Rail Fish Phaj?
Ib txoj kev tsheb ciav hlauphaj ntses(joint bar) yog ib qho khoom siv txuas ntxiv uas txuas cov kab tsheb ciav hlau kom taug qab geometry thiab qhov tawv nqaij ruaj khov nyob rau hauv cov pob qij txha thaum rov ua dua lub tsheb ciav hlau. Nws qhov tseeb ncaj qha cuam tshuam rau kev sib koom ua ke. Ntses daim hlau yog tsim rau GB lub teeb rail thiab hnyav rail, UIC profiles,TIAB SA 536thiabQU crane rails, JIS rail seem, AS 1085 rails, BS 11 profiles thiab AREMA / ASCE rails.
Hom Rail Joint Bars
| Hom | Lub luag haujlwm tseem ceeb |
|---|---|
| Txheem ntses daim hlau | Txuas kev tsheb ciav hlau xaus ntawm tib qhov loj, feem ntau nrog 4 lossis 6 qhov, rau cov qauv tsheb ciav hlau |
| Insulated ntses daim hlau | Hluav taws xob cais cov kab hluav taws xob rau cov khoom siv hluav taws xob siv cov khoom siv tsis yog -cov khoom siv hluav taws xob |
| Compromise ntses daim hlau | Hloov cov pob qij txha txuas cov hlua ntawm qhov sib txawv lossis cov profiles |
| Joggled ntses daim hlau | Khoov zoo rau kev kho ib ntus lossis kom haum raws li kev tsheb nqaj hlau |
| Glued insulated pob qij txha (GIJ) | Siab- lub zog sib koom ua ke uas txo qis kev txav ntawm siab - nrawm lossis hnyav- qag kab |
| Crane rail ntses daim hlau | Hnyav- cov ntawv ua haujlwm rau crane rail profiles (piv txwv li QU70, QU100, QU120) |
Puas yog insulated ntses daim hlau xav tau rau txhua txoj kev tsheb ciav hlau?
Insulated ntses daim hlau (los yog insulated rail pob qij txha) tsis xav tau rau tag nrho cov tsheb ciav hlau lem; lawv yuav tsum tau tshwj xeeb nyob rau hauv cov cheeb tsam uas muaj hluav taws xob signaling systems, taug qab circuits, los yog ntawm turnouts los tiv thaiv hluav taws xob cuam tshuam. Lawv yog ib qho tseem ceeb heev rau kev sib cais cov kab khiav, thaum tus qauv, tsis yog - cov phaj hlau insulated yog siv rau ntawm cov kab khiav raws li qhov kev rwb thaiv tsev tsis tsim nyog.
Thaum rwb thaiv tsev yog qhov tseem ceeb
- Signaling systems:Qhov tseem ceeb qhov twg cov kab hluav taws xob siv rau kev tshawb nrhiav tsheb ciav hlau.
- Electrified lem:tseem ceeb heev nyob rau hauv electrified railway systems kom tswj hluav taws xob cais.
- Kev sib tw thiab kev ua haujlwm tshwj xeeb:siv ntawm turnout hloov dua siab tshiab qhov chaw los tiv thaiv tam sim no los ntawm cuam tshuam nrog turnout tswj circuits.
- Choj/tunnel kev nyab xeeb:feem ntau yuav tsum tau nyob rau hauv qhov chaw ntub dej los tiv thaiv hluav taws xob.
Thaum Tsis Xav Tau
- Cov qauv tsis yog- cov cim qhia kev tsheb ciav hlau lossis cov ntu kev tsheb ciav hlau uas tsis tas yuav tsum muaj hluav taws xob cais tawm.
- Niaj hnub nimno tsis tu ncua welded rail (CWR) yuav xav tau cov pob qij txha tsawg dua; tab sis qhov khoob qhov xav tau rau kev taw qhia, kev rwb thaiv tsev tseem tseem ceeb heev.
Cov ntaub ntawv dab tsi yog siv rau Rail Joint Bars?
Rail ob leeg tuav (los yog ntses phaj) feem ntau yog tsim los ntawm siab - lub zog carbon steel, xws li 45 #, 50 #, 55 # steel, los yog alloy steels zoo li 50Mn rau kev txhim kho durability. Lawv yog tsim los tiv thaiv hnyav railway, crane los yog lub teeb rail loads. Tshwj xeeb insulated pob qij txha siv siab -cov ntaub ntawv muaj zog sib xyaw los muab kev sib cais hluav taws xob.
| Khoom siv | Hom Qib | Sau ntawv |
|---|---|---|
| Carbon steel qauv | Q235 (GB/T 700) | Cov hlau me me rau kev sib koom ua ke; zoo ib yam li ASTM A36, S235JR |
| Nruab nrab carbon steel | 50Mn / 55 # (GB / T 699) | Classic siab -lub zog ntses phaj hlau rau cov pob qij txha loj |
| Hlau alloy | 42CrMo (GB/T 3077) | Siab -lub zog, siab -toughness alloy rau kev pabcuam hnyav; zoo ib yam li AISI 4140 |
| Spheroidal graphite cam khwb cia hlau | QT450-10 (GB/T 1348) | Siv rau hauv qee cov khoom siv sib koom ua ke rau castability thiab damping |
| Insulating sib xyaw | Epoxy fiberglass / FRP | Hluav taws xob rwb thaiv tsev (resistivity> 10¹² Ω·cm), corrosion kuj |
Siv cov phaj ntses txheem rau cov pa sib koom ua ke; qhia cov phaj insulated ntses (los yog glued insulated pob qij txha) nyob qhov twg los xij ntawm cov kab hluav taws xob, kev taw qhia, hluav taws xob lossis kev tswj hluav taws xob yuav tsum muaj hluav taws xob sib cais.
Thov Insulated Fish Plate Nqe
Insulated ntses daim hlau yog qhov tseem ceeb uas yuav tsum tau taug qab circuits, signaling, lossis hluav taws xob cais tawm; lawv tsis tsim nyog rau txhua txoj kev tsheb ciav hlau. Hom raug xaiv yuav tsum raug xaiv raws li cov cim qhia, kev tsheb ciav hlau profile, thiab kev sib koom ua ke.GNEE RAILkhoom siv insulated thiab txheem ntses daim hlau rau txawv rail systems thiab khiav yuav tsum tau.
