1. Yuav ua li cas fastening systems tuav lub zog dynamic ntawm tsheb ciav hlau braking ntawm ntxhab gradients?
Braking ntawm gradients tsim cov kev sib tw ntev ntev ntawm kev tsheb nqaj hlau, yuav tsum tau ceev cov tshuab nrog txhim kho tuav. Cov tshuab no siv serrated rail clips, ntxiv bolts, los yog dual -clip tsim los tiv thaiv kev tsheb ciav hlau creep. Ntawm 3% + gradients, fastening spacing yog txo (los ntawm 600mm mus rau 450mm) kom faib quab yuam. Qee lub tshuab suav nrog cov tsheb ciav hlau thauj tog rau nkoj (nrog rau cov neeg pw tsaug zog) txhawm rau thaiv kev tsheb nqaj hlau rov qab, nrog rau kev kuaj lub zog tsis tu ncua tom qab cov xwm txheej hnyav.
2. Dab tsi yog qhov kev hloov kho tshiab ntawm tus kheej -locking fastening systems kom tsis txhob xoob?
Tus kheej- kaw tshuab siv cov xov deformed, nylon inserts, los yog cam mechanisms los tiv thaiv kev co -induced loosening. Cov qauv tsim tsis ntev los no suav nrog "ntse" cov txiv ntseej nrog ua- nyob rau hauv cov sensors uas ceeb toom thaum nro poob qis dua 80% ntawm qhov tshwj xeeb. Nplhaib-puab clips (piv txwv li, KPO clips) tsim kom muaj kev sib txhuam ntau dua li kev vibration intensifies, tuav tuav. Cov kev tsim kho tshiab no txo qis kev saib xyuas ntau zaus los ntawm 50% hauv siab - thaj chaw vibration xws li tsheb thauj mus los hauv nroog.
3. Yuav ua li cas fastening systems rau cov cuab yeej cuab tam railways txawv ntawm niaj hnub systems?
Cov cuab yeej cuab tam feem ntau siv cov qauv tsim keeb kwm (xws li, cov rooj zaum bullhead rail nrog cam khwb cia-hlau yuam sij) kom phim vintage dov Tshuag. Lawv muab qhov tseem ceeb sib xws nrog cov tsheb ciav hlau qub tshaj li kev ua tau zoo, siv tes-tightened Cheebtsam. Cov tshuab niaj hnub no tsom rau kev ua haujlwm zoo thiab kev nyab xeeb, nrog kev hloov kho clips thiab corrosion kuj. Cov cuab yeej cuab tam fasteners xav tau kev tsim tshwj xeeb kom rov ua cov khoom qub, thaum cov niaj hnub siv cov qauv tsim, pawg- cov khoom tsim.
4. Dab tsi yog qhov cuam tshuam ntawm ib puag ncig ntawm cov khoom sib txawv fastening system (steel vs. composite)?
Steel fasteners muaj siab embodied carbon tab sis yog 100% recyclable. Composite (fiber-cov khoom siv polymer) fasteners txo qhov hnyav thiab corrosion, txo qis kev thauj mus los, tab sis lawv cov khoom siv rov ua dua tshiab yog txwv. Cov tshuab hlau muaj lub neej ntev dua (30+} xyoo) nyob rau hauv cov huab cua nruab nrab, thaum cov khoom sib xyaw ua tau zoo nyob rau hauv ib puag ncig corrosive, ntsuas lub neej voj voog ib puag ncig tus nqi. Cov neeg tsim khoom tau nce siv cov hlau rov ua dua tshiab thiab bio-raws li kev sib xyaw kom txo tau qhov cuam tshuam
5. Yuav ua li cas fastening systems nyob rau hauv tunnels daws teeb meem qhov cua thiab av noo?
Tunnel fastening systems siv corrosion-cov tshuaj tiv thaiv (epoxy lossis zinc-nickel) los tiv thaiv cov av noo siab. Lawv tau tsim los nrog cov dej ntws los tiv thaiv cov dej hauv ib puag ncig bolts, thiab feem ntau suav nrog cov khoom siv rwb thaiv tsev kom tsis txhob muaj hluav taws xob cuam tshuam nrog lub qhov taub. Qhov cua tshuab cua tuaj yeem ua rau muaj kev vibration, yog li qhov txuas fasteners siv cov txheej txheem kaw kom zoo (xws li, ob lub txiv ntoo) los tiv thaiv kev xoob. Kev tshuaj xyuas tsis tu ncua (ib lub hlis twg) xyuas cov dej noo-induced corrosion.
