Yuav ua li cas xaiv Railway Qav Bolts: Lub zog, Qhov loj me thiab kev saib xyuas
1. Dab tsi yog Qav Bolts?
Qav boltsyog cov bolts siv nyob rau hauv txoj kev tsheb ciav hlau turnouts kom ruaj ntseg Qav - tus hla kev tivthaiv qhov twg lub log hloov ntawm txoj kab ntawm kab thiab txoj kab sib txawv. Lawv fasten cov qag rails (tis rails thiab taw tes rail) rau khi daim hlau los yog hla lub hauv paus, thiab cov clamp bolts zoo sib xws yog siv rau lwm qhov hauv cov qauv tig tawm. Vim tias cov kev hloov pauv tau muaj kev cuam tshuam loj thiab kev vibration, Qav bolt xaiv ncaj qha cuam tshuam rau kev hla kev nyab xeeb thiab kev pabcuam lub neej.
2. Cov txheej txheem xaiv
| Cov txheej txheem | Kev txiav txim siab |
|---|---|
| Qib zog | Sib piv cov qib bolt (piv txwv li. 8.8 / 10.9 siab-tensile ib ISO 898-}1, lossis cov phiaj xwm tshwj xeeb) rau hauv chav kawm qag thiab tsheb khiav |
| Loj thiab xov | Txoj kab uas hla thiab qhov ntev kom haum rau Qav baseplate qhov qauv thiab stacked thickness; raug xov daim ntawv thiab suab |
| Khoom siv | Siab -tensile alloy steel (xws li . 40Cr, 35CrMo lossis sib npaug) rau kev qaug zog |
| Txheej | Zinc plating, Dacromet lossis kub -dip galvanizing rau qhov chaw ua haujlwm |
| Anti-loosing tsim | Caij nplooj ntoos hlav ntxhua khaub ncaws, xauv txiv ntseej lossis xov-locking compound - turnout bolts raug kev co hnyav thiab cuam tshuam |
| Kev ua raws cai | Txheeb xyuas cov qauv kev tsheb ciav hlau uas siv tau (TB/T, UIC lossis AREMA) thiab qhov project specification |
3. Cov txheej txheem xaiv
- Txhais hom turnout, rail profile thiab qag -load class ntawm kab.
- Txiav txim siab qhov yuav tsum tau muaj zog bolt qib thiab corrosion- qib tiv thaiv.
- Paub meej tias qhov ntev tiv thaiv cov Qav baseplate drawings.
- Yuav tsum tau daim ntawv pov thawj cov ntaub ntawv thiab batch test report los ntawm tus neeg muag khoom.
4. Kev kuaj xyuas thiab tu tsis tu ncua
- Ua kom txoj kev hla kev hla kev tsheb ciav hlau thiab kev tawm mus kom nyab xeeb los ntawm kev tshuaj xyuas thiab tswj cov bolts.
- Nyob rau hauv huab cua tsis zoo (los nag hnyav, huab cua txias, dej nyab), ua kev kuaj xyuas ntxiv kom sai sai rau txhua yam teeb meem.
- Txheeb xyuas torque raws sij hawm; hloov bolts uas qhia tias xoob, corrosion, tawg los yog xov puas tam sim ntawd.
Thov Qav Bolt Nqe
Qav bolt xaiv zoo nyob ntawmlub zog, qhov ntev, rail profile, turnout tsim, thiab kev khiav hauj lwm tej yam kev mob. Kev txhim kho kom raug thiab kev tshuaj xyuas tsis tu ncua pab tswj kev ruaj ntseg thiab kev pabcuam lub neej.GNEE RAILkhoom siv Qav bolts thiab tshaj railway fastening Cheebtsam rau sib txawv turnout thiab khiav yuav tsum tau.
