A rail ntses phaj yog ib qho cuab yeej cuab tam sib koom ua ke tsim los txhim kho txoj kev tsheb ciav hlau xaus rau txoj kab ntsug ntsug, kev txav mus rau sab nraud, thiab kev txav mus ntev, kom ntseeg tau tias cov log tsheb tau muab faib rau ob qho tib si es tsis txhob tsom ntawm ib qho kawg.GNEE RAILmuab cov phaj ntses rau GB 8–60 kg/m, UIC50–UIC60, DIN536 A-series, QU crane rails, JIS qauv, AS1085 rails, BS11 profiles, thiab AREMA / ASCE cov qauv, thiab txhawb cov neeg siv khoom nrog kev sib koom tsim kev xaiv thiab kev sib koom ua ke.
Dab tsi yog qhov sib txuas ua ke?
Glued pob qij txha (los yog Glued Insulated Rail Joints, GIRJ) nyob rau hauv railways yog siab -lub zog, insulated, thiab, nyob rau hauv ntau rooj plaub, Hoobkas- tsim rail pob qij txha siv los txuas rails thaum tiv thaiv hluav taws xob los ntawm lawv. Lawv muaj cov web-fitting fishplates, siab-tensile bolts, thiab tshwj xeeb epoxy nplaum.
Qhov tseem ceeb ntawm Glued Joints:
- Lub hom phiaj:Feem ntau siv rau cov kab hluav taws xob khiav hauv cov khoom siv hluav taws xob, tso cai rau hluav taws xob sib cais ntawm cov kab tsheb ciav hlau tsis muaj kev cuam tshuam cov neeg kho tshuab txuas ntxiv ntawm txoj kev tsheb ciav hlau.
- Cov khoom xyaw:Lawv siv insulating sab channel, kawg posts (feem ntau fiber ntau- iav reinforced), thiab siab -lub zog nplaum (feem ntau epoxy) los tsim ib daim ntawv cog lus ruaj khov.
Hom:
- Factory-ua (S-type):Fabricated nyob rau hauv kev tswj tej yam kev mob rau siab tshaj plaws zoo thiab ntev.
- Hauv -situ (Field- sib dhos):Glued thiab assembled ncaj qha rau ntawm tus khiav.
- Piv txwv kev siv:Cov pob qij txha no tau siv dav hauv kev taug qab- thaj chaw sib kis, siab - txoj kev tsheb khiav, hloov pauv, thiab kev tawm mus kom muaj kev nyab xeeb thiab teeb pom kev zoo.
Yuav ua li cas txheeb xyuas cov pob qij txha hauv kev tsheb ciav hlau?
Glued insulated joints (GIJ) in railways are checked for integrity, insulation, and wear through electrical resistance testing (using a Megger, >25 MΩ dry, >3 kΩ ntub dej) thiab kev tshuaj xyuas qhov muag rau xoob / tawg bolts, puas kawg posts, los yog nplaum tsis ua hauj lwm (qhov khoob). Kev saib xyuas tsis tu ncua suav nrog kev tshuaj xyuas lub zog ntawm lub zog, tso dej, thiab kev tsheb ciav hlau kawg kom paub meej cov kab hluav taws xob txuas ntxiv thiab kev nyab xeeb ntawm cov qauv.
Txoj Kev Tshuaj Xyuas Tseem Ceeb rau Glued Joints:
- Kev Ntsuas Hluav Taws Xob Hluav Taws Xob (Megger Test): Siv 100V DC hla kev sib koom ua ke los ntsuas kev tiv thaiv. Cov pob qij txha tshiab yuav tsum muaj 10MΩ, thaum cov pob qij txha uas twb muaj lawm yuav tsum muaj kev tiv thaiv siab feem ntau tshaj 25MΩ nyob rau hauv qhuav qhuav, los yog yam tsawg kawg nkaus 3kΩ tom qab 48-teev dej immersion).
- Kev Tshuaj Xyuas Kev Pom Zoo: Tsis tu ncua xyuas cov ntses phaj tawg, xoob lossis tawg bolts, thiab cov ncej tawg.
- Kev Tshawb Fawb Lub Cev: Tshawb xyuas qhov tsis sib xws ntawm txoj kev tsheb ciav hlau thiab lub phaj phaj (qhia tias daim ntawv cog lus tsis ua haujlwm) thiab tshuaj xyuas qhov xwm txheej ntawm cov khoom siv rwb thaiv tsev.
- Kev Ntsuas Ultrasonic: Siv los txheeb xyuas qhov tsis zoo hauv cov tsheb ciav hlau thiab kev sib koom ua ke.
- Kev tu thiab khaws cov ntaub ntawv: xyuas kom qhov chaw pw tsaug zog thiab tso dej kom zoo. Txhua qhov kev tshuaj xyuas yuav tsum tau sau tseg, nrog rau kev saib xyuas tshwj xeeb thaum lub caij ntuj no (Lub Xya Hli -September) rau kev sib cog lus- txog cov teeb meem.
Founded hauv 2008,GNEE RAILyog lub chaw tsim khoom lag luam thoob ntiaj teb thiab cov khoom lag luam ntawm cov khoom siv tsheb ciav hlau, tshwj xeeb hauv siab - zoorail ntses daim hlau(cov khoom sib koom ua ke / cov kab sib txuas) nrog lub peev xwm ntau lawm thiab kev pabcuam thoob ntiaj teb.
