Lub phaj phaj yog dab tsi?
A phaj ntses(los yog sib koom ua ke bar / splice bar) yog ib qho tshwj xeeb, dov steel phaj bolted rau lub vev xaib ntawm ob txoj kev tsheb ciav hlau xaus rau hauv txoj kev ceev ceev. Nws ua raws li tus qauv choj, ua kom muaj kev sib raug zoo, tswj kev ntsug / kab rov tav txuas ntxiv, thiab tso cai rau kev nthuav dav kev tsheb nqaj hlau, feem ntau pom nyob rau hauv ob sab ntawm kev sib koom ua ke.
GNEE RAILmuab ntses daim hlau haum rau GB lub teeb thiab hnyav rails, UIC txheem rails, DIN536 thiab QU crane rail systems, JIS rail profiles, AS1085 seem, BS11 rails, thiab AREMA / ASCE rail specifications, muab ib tug - nres tsheb ciav hlau sib koom kev daws teeb meem.
Cov Ntsiab Lus Tseem Ceeb ntawm Cov Phaj Ntses:
- Tsim & Ua Haujlwm:Tsim los nrog cov ntaub ntawv tapered (ntub nruab nrab, thinner kawg) kom haum snugly rau hauv txoj kev tsheb ciav hlau lub vev xaib, tiv thaiv txoj kab ntsug lossis sab nraub qaum thiab txhawb nqa cov tsheb ciav hlau hla.
- Cheebtsam:Lawv yog siv los ua ke nrog cov ntses bolts, uas dhau los ntawm qhov hauv lub vev xaib tsheb ciav hlau thiab cov phiaj.
- Khoom siv:Feem ntau yog tsim los ntawm siab- steel zoo (xws li, carbon steel, manganese steel) kom tiv taus siab thiab hnyav.
- Hom:Standard, insulated (rau signaling systems), thiab tshwj xeeb / jogged daim hlau muaj nyob rau hauv raws li cov kev xav tau ntawm tsheb thauj mus los thiab rail profiles.
Daim phiaj ntses yog qhov tseem ceeb rau kev tswj xyuas cov txheej txheem kev ncaj ncees ntawm txoj kev tsheb ciav hlau, tiv thaiv kev tsheb ciav hlau sib cais, thiab ua kom muaj kev ruaj ntseg, nyab xeeb, thiab caij tsheb.
Daim phiaj ntses yog dab tsi?
Ntses daim hlau (railway ob leeg tuav) feem ntau yog ua los ntawm siab - lub zog steel, nrog rau forged steel, dov hlau, thiab carbon steel (xws li Q235, 45#, 50Mn, 42CrMo), xaiv rau durability, siab qaug zog, thiab lub zog nyob rau hauv hnyav loads. Cov hom tshwj xeeb, xws li cov khoom siv hluav taws xob, tuaj yeem siv cov ntaub ntawv sib xyaw ua ke.
