A rail ntses phaj yog ib qho kev sib txuas uas sib koom ua ke ntawm txoj kev tsheb ciav hlau uas nyob ib sab mus rau hauv cov kab hluav taws xob txuas ntxiv, ua kom muaj kev nyab xeeb ntawm kev thauj khoom qag thaum tswj kev tsheb ciav hlau kawg los ntawm kev vibration thiab thermal cycling. Nws qhov kev ua tau zoo cuam tshuam rau kev sib koom ua ke ntev.
GNEE RAILmuab cov ntses daim hlau rau GB lub teeb thiab hnyav rails, UIC rail profiles, DIN536 thiab QU crane rails, JIS rails, AS1085 seem, BS11 profiles, thiab AREMA / ASCE rails, nrog rau cov kev pab cuam nrog rau kev tiv thaiv corrosion thiab kev sib koom pob khoom.
Dab tsi yog qhov kev ua haujlwm ntawm lub tsheb ciav hlau sib koom ua ke?
Ib lub tsheb ciav hlau sib koom ua ke (lossis ntses phaj) txuas ob txoj kev tsheb ciav hlau, tswj kev sib tw, kev ruaj ntseg, thiab hluav taws xob conductivity thaum tso cai rau thermal expansion. Cov hlau tuav no ua kom muaj kev sib luag, txuas ntxiv mus rau kev tsheb ciav hlau, faib cov khoom kom txo tau kev ntxhov siab, tiv thaiv kev sib cais, thiab tswj kev ntsuas kom zoo. Lawv yog qhov tseem ceeb rau kev nyab xeeb ntawm kev taug qab.
Lub luag haujlwm tseem ceeb ntawm Rail Joint Bar:
- Txuas Rails:Koom nrog ob txoj kev tsheb ciav hlau uas nyob ib sab ua ke los tsim kom muaj kev sib txuas ntxiv.
- Kev ruaj ntseg Alignment:Khaws cov ntsia hlau nyob rau hauv txoj kab rov tav thiab ntsug kom ua kom zoo, kev nyab xeeb tsheb ciav hlau txav.
- Load Distribution:Txo kev ntxhov siab ntawm kev sib koom ua ke, hloov cov khoom siv tau zoo.
- Tso Cai Expansion/Contraction:Muab qhov chaw tsim nyog rau thermal txav ntawm cov ntsia hlau, tiv thaiv buckling lossis qhov khoob.
- Kev nyab xeeb & ruaj ntseg:Tuav cov ntsia hlau ua ke los tiv thaiv kev sib cais ntawm cov tsheb ciav hlau thiab derailments.
Insulated rail sib koom specification
Insulated rail pob qij txha (IRJs), los yog glued insulated pob qij txha (GIJs), yog cov teeb liab tseem ceeb tsim los rau kev sib cais hluav taws xob ntawm cov kab hluav taws xob. Cov ntsiab lus tseem ceeb yuav tsum muaj qhov tsawg kawg nkaus ntawm 30 MΩ hluav taws xob tiv thaiv, nrog rau kev hloov pauv yuav tsum yog qhov tsis kam poob qis dua 1 MΩ lossis 3 MΩ rau qhov ua tsis tiav). Lawv yuav tsum tiv taus axial loads tshaj 2500KN thiab qag loads txog 320KN.
Ntsiab Technical Specifications:
- Structure: Muaj steel fishplates, tshwj xeeb rwb thaiv tsev liners (feem ntau nylon 66 los yog fiberglass), insulated kawg posts, thiab insulated bolt tes tsho / washers.
- Cov qauv: Ua raws li cov qauv thoob ntiaj teb xws li AREMA (115RE, 132RE), UIC (UIC54, UIC60), BS, lossis GB qauv.
- Dimensions & Tolerance: Tus qauv ntev yog feem ntau 12.5m lossis customized, nrog kev sib koom ua ke ntev ntawm 3.43m txog 4.57m. Kev kam rau lub qhov chaw yog feem ntau ± 1mm.
- Kev ua tau zoo: Tsim los ua lub tsev monolithic, tiv thaiv kev sib txheeb ntawm kev tsheb ciav hlau thiab cov ntses.
- Yuav tsum tau txhim kho: Glued pob qij txha yuav tsum tau ntsia thaum kub siab tshaj 12℃thiab av noo qis dua 60%.
- Kev Kho: Kev tiv thaiv rwb thaiv tsev yuav tsum tau kuaj xyuas tsawg kawg peb lub hlis twg, nrog rau kev saib xyuas tshwj xeeb kom tshem tawm cov ntaub ntawv hlau lossis cov plua plav nres uas tuaj yeem tsim cov luv luv.
Qhov loj ntawm Rail Joint
Rail pob qij txha (ntses daim hlau) sib txawv raws li qhov hnyav ntawm kev tsheb nqaj hlau, xws li lub teeb (8kg-30kg) mus rau hnyav (38kg-60kg) thiab crane rails (QU70-QU120). Cov qauv ntev yog feem ntau 24-nti (4-qhov) lossis 36-nti (6-qhov). Cov qauv thoob ntiaj teb muaj xws li 115RE, 132RE, UIC54, UIC60, thiab ntau yam qauv BS80A.
