Dab tsi ua rau Cov Ntses Plate Failures hauv US Railways?
Feem ntau cov ntses phaj (chaw sib koom ua ke) tsis ua haujlwm hauv Asmeskas kev tsheb ciav hlau feem ntau yog tshwm sim los ntawm lub qhov taub ntawm lub qhov qaug zog tawg, qhov tsis zoo ntawm lub qhov rooj torque, ib puag ncig corrosion, thiab kev ntxhov siab ntau dhau los ntawm lub nra hnyav. Cov xwm txheej no ua rau cov phaj tawg, cov kev sib txuas xoob, lossis tawg rail xaus.
Cov laj thawj tseem ceeb ntawm cov ntses phaj ua tsis tiav muaj xws li:
- Mechanical Stress and Load: Heavy freight traffic, tshwj xeeb tshaj yog nyob rau hauv siab -ceev los yog hnyav- txoj kev taug kev, ua rau mob hnyav thiab hnav.
- Bolt Hole Fatigue: Kwv yees li 40% ntawm kev tsheb ciav hlau tawg ntawm kev sib koom ua ke tuaj ntawm lub qhov ntsia hlau vim muaj kev ntxhov siab ntau.
- Kev Txhim Kho / Kev Kho Tsis Zoo: Qhov ntawd nyob rau hauv - torqued bolts (looseness) lossis dhau - torqued bolts (kev ntxhov siab) feem ntau ua rau tsis ua haujlwm.
- Environmental Factors: Moisture, xeb, thiab kub kub hloov pauv ua rau cov khoom degradation thiab expansion/contraction stress.
- Cov Khoom Siv Tsis Zoo: Cov hlau tsis zoo lossis cov khoom siv tsis zoo tuaj yeem ua rau tsis ua haujlwm.
Hom Kev Ua Tsis Zoo
- Cov phaj tawg / tawg: Feem ntau tshwm sim ntawm qhov chaw, tshwj xeeb tshaj yog nyob rau hauv qis, siab - cheeb tsam nro.
- Bolt Slackening: Kev vibrations los ntawm cov tsheb hnyav tuaj yeem ua rau cov bolts loosen.
- Cov teeb meem sib koom ua ke: Kev tsim kho tsis raug lossis khaws cia qhov tsis sib xws tuaj yeem ua rau txoj kev tsheb ciav hlau kawg.
Yuav ua li cas tiv thaiv cov teeb meem xws li xeb thiab tawg ntawm kev sib koom ua ke ntawm rail?
Tiv thaiv kom tsis txhob xeb thiab tawg hauv kev sib koom ua ke ntawm txoj kab tsheb ciav hlau (ntses daim hlau) yuav tsum muaj kev sib xyaw ua ke ntawm kev saib xyuas, kev teeb tsa kom raug, thiab kev tiv thaiv. Cov haujlwm tseem ceeb muaj xws li lubrication zoo ib yam los tiv thaiv xeb, zawm bolts nrog lub torque ciaj ntswj, niaj hnub tshuaj xyuas cov kab nrib pleb, thiab siv cov qib siab - zoo tiv thaiv - corrosion coatings los xyuas kom meej cov qauv thiab tiv thaiv kev qaug zog.
Kev Tiv Thaiv Tseem Ceeb rau Rail Joint Bars:
Tiv thaiv Corrosion (Xeb):
- Lubrication: tsis tu ncua siv cov roj nplua nyeem tsim nyog rau cov khoom sib koom ua ke thiab cov chaw nuv ntses kom txo tau kev sib txhuam, pub dawb txav, thiab tiv thaiv kom tsis txhob ya raws - vim xeb.
- Cov Txheej Txheem Tiv Thaiv: Siv cov txheej txheem siab heev, xws li zinc-raws li, lossis tshwj xeeb los tiv thaiv- kev kho corrosion, los tiv thaiv cov hlau los ntawm ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv ntug dej hiav txwv lossis chaw lag luam.
- Ntxuav: Tsis tu ncua tshem tawm cov av, cov khib nyiab, thiab cov xuab zeb los ntawm qhov chaw sib koom ua ke kom tiv thaiv kom tsis txhob ya raws thiab ua kom nrawm dua.
Tiv thaiv kev tawg thiab ua tsis tiav:
- Kev Txhim Kho Kom Zoo: Ua kom muaj kev sib raug zoo ntawm qhov sib koom ua ke thiab siv qhov tsim nyog nruj torque ntawm cov ntses bolts siv lub torque wrench.
- Kev tshuaj xyuas tsis tu ncua: Nquag tshuaj xyuas cov kab sib koom ua ke rau cov cim qhia ntawm hnav, kab plaub hau tawg, lossis xeb.
- Bolt Tension Management: Tswj kom nruj nruj ntawm bolts, raws li cov bolts xoob tuaj yeem ua rau muaj kev ntxhov siab ntau dhau, ua rau tawg.
- Kev xaiv cov khoom siv: Siv siab - zoo, siab - lub zog steel rau kev sib koom ua ke, tsim los tiv thaiv hnyav, rov ua dua.
- Kev Tswj Kub Kub: Hauv kev sib koom ua ke, xyuas kom muaj qhov sib txawv ntawm qhov sib txawv kom tsis txhob muaj cua sov los yog kev sib zog ntau dhau thaum huab cua txias, uas tuaj yeem ua rau cov kab sib koom ua ke.
- Hloov pauv: Hloov cov khoom hnav, tawg, lossis cov kab sib koom ua ke hnyav heev kom tsis txhob ua tsis tiav.
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.
Peb rail ntses phaj portfolio muaj kev txawj ntse thiab ua raws li thoob ntiaj teb cov qauv xws li UIC, AREMA, BS, DIN, thiab GB, npog lub teeb rail (8kg-30kg), hnyav rail (38kg-75kg), thiab crane rail (QU70-QU120) systems. Peb muaj ntau hom xws li insulated ob leeg tuav, bulged ntses daim hlau, thiab kev cuam tshuam kev tsheb nqaj hlau pob qij txha, nrog meej specifications (4-qhov / 6-qhov, 24-nti / 36-nti), kom ntseeg tau zoo heev mechanical kev ua tau zoo.Peb tuav nruj zoo tswj kev txhawb nqa los ntawm ISO 9001: 2015 nyob rau hauv ib qho chaw thib peb-tsim kev soj ntsuam, SGS thiab BV. Peb qhov kev pabcuam ib leeg suav nrog kev tsim kho, tsim khoom, ntim khoom, thiab kev txhawb nqa tom qab muag, haum rau cov neeg siv khoom xav tau.
