1. Yuav ua li cas fastening systems tuav lub thermal expansion ntawm rails nyob rau hauv cov suab puam cheeb tsam?
Cov suab puam fastening tshuab tso cai rau kev tsheb ciav hlau ntau dua (txog 20mm) ntawm zawv zawg clips thiab txuas txuas ntxiv. Lawv siv cov cua sov- cov roj nplua nyeem tiv thaiv kom tsis txhob cuam tshuam clip hauv 50℃+ kub. Cov fasteners yog spaced kom sib npaug stability thiab yooj, nrog nro hloov raws caij nyoog rau tus account rau huab cua kub swings. Stainless hlau Cheebtsam tiv tshav kub-induced corrosion, ncua lifespan nyob rau hauv arid tej yam kev mob
2. Dab tsi yog qhov kev saib xyuas rau cov txheej txheem fastening nyob rau hauv siab - tsheb khiav hauv nroog?
Siab - tsheb khiav hauv nroog (xws li subway) yuav tsum tau tshuaj xyuas txhua lub limtiam ntawm qhov nro clip thiab xyuas txhua hli rau corrosion. Elastic clips yog re-tensioned peb lub hlis twg, thaum lub tshuab bolted xav tau kev txheeb xyuas qhov tseeb txhua 6 lub hlis. Lub nroog fasteners feem ntau siv sai - tso tawm cov qauv tsim kom txo tau cov sijhawm kaw thaum lub sijhawm tu. Suab nrov-dampening Cheebtsam (xws li, roj hmab pads) yog hloov txhua xyoo los tswj kev ua tau zoo.
3. Yuav ua li cas fastening systems rau monorails txawv ntawm cov pa ob -rail systems?
Monorail fasteners ruaj ntseg ib qho kev tsheb ciav hlau mus rau cov qauv siab, siv cov hlua khi thiab ntsug los tiv thaiv tilting. Lawv yog lub teeb yuag (txhuas los yog sib xyaw) kom txo tau cov qauv thauj khoom thiab muaj kev sib raug zoo (± 0.2mm) rau kev taw qhia kev ruaj ntseg. Cov txheej txheem ib txwm tsom rau kev ntsuas kev saib xyuas ntawm ob txoj kab tsheb ciav hlau, thaum monorail fasteners tseem ceeb tshaj qhov kev faib khoom ntsug thiab kev sib raug zoo nrog lub tsheb ciav hlau qhia lub log.
4. Dab tsi tshiab nyob rau hauv txheej txheej technology txhim kho fastening system durability?
Cov txheej txheem qib siab suav nrog graphene- ntxiv dag zog rau zinc, uas ua rau muaj kev tiv thaiv corrosion piv rau cov qauv galvanization. Ceramic-polymer composites tiv thaiv kev puas tsuaj thiab kub kub, zoo tagnrho rau thaj chaw muaj kev lag luam. Tus kheej- kho cov txheej txheem nrog microcapsules tso tawm cov tshuaj tiv thaiv corrosion thaum khawb, ncua kev txij nkawm los ntawm 2-3 xyoos. Cov txheej txheem no raug sim los ntawm 1,000-teev cov tshuaj tsuag ntsev kom ntseeg tau tias kev ua haujlwm
5. Yuav ua li cas fastening systems nyob rau hauv lub txias huab cua nyob rau hauv lub frosts heave thiab ice buildup?
Txias-cov huab cua huab cua siv cov khoom frost-cov ntaub ntawv tiv taus (piv txwv li, qis-cov roj hmab kub) kom tsis txhob nkig. Lawv suav nrog cov dej khov- cov tshuaj tiv thaiv kab mob los tiv thaiv cov khib nyiab khov los ntawm kev sib tsoo. Fasteners yog mounted saum toj tej zaum Frost kab, nrog adjustable qhov siab nta kom them rau heave. Hauv cov daus-cov cheeb tsam, lawv tau tsim los los daus daus, txo cov load thiab dej khov txaus ntshai.
