1. Lub caij nplooj ntoos hlav tsim txawv li cas rau 30kg / m teeb rails vs . 75kg / m hnyav rails?
Springs rau 30kg / m rails yog lub teeb yuag nrog tsawg coils (4-6) kom zoo dua vibration absorption. Cov rau 75kg / m rails muaj ntau coils (8-10) thiab thicker hlau los tuav hnyav loads, kom ntseeg tau tias tsawg deflection nyob rau hauv siab.
2. Dab tsi yog lub neej ntev ntawm lub caij nplooj ntoos hlav sib xyaw nrog lub caij nplooj ntoos hlav steel hauv thaj chaw suab puam?
Composite springs kav 10-15 xyoo nyob rau hauv cov suab puam, tiv thaiv UV degradation nrog additives. steel springs, txawm tias muaj txheej txheej, tuaj yeem corrode hauv cov xuab zeb- cua daj cua dub, yuav tsum tau hloov txhua 8-12 xyoo.
3. Yuav ua li cas cov nplooj springs nrog cov lej sib txawv ntawm cov phaj ua haujlwm raws li qhov sib txawv?
Nplooj springs nrog 3-4 daim hlau haum lub teeb loads (cov neeg caij tsheb ciav hlau), thaum 5-7 daim hlau tuav cov khoom thauj hnyav. Ntau daim hlau faib qhov hnyav sib npaug, tiv thaiv sagging, thaum tsawg daim hlau txhim kho kev caij tsheb zoo.
4. Lub luag haujlwm dab tsi ua haujlwm hauv kev tswj kev tsheb ciav hlau rau kev nkhaus?
Springs nrog asymmetric designs siv ntau dua lateral quab yuam ntawm sab hauv rail ntawm nkhaus, counteracting centrifugal siab. Qhov no tiv thaiv kev hloov tsheb ciav hlau, ua kom muaj kev sib haum xeeb txawm tias nyob rau hauv siab - ceev lossis hnyav thauj khoom.
5. Cov ntaub ntawv sib txawv ntawm lub caij nplooj ntoos hlav cuam tshuam li cas rau thermal expansion nyob rau hauv huab cua kub?
Polyurethane springs muaj thermal expansion ntau dua (xav tau qhov khoob rau kev nthuav dav), thaum steel springs nthuav me me, tswj kev ruaj ntseg. Hauv cov suab puam lossis thaj tsam arctic, cov hlau yog nyiam rau kev ua tau zoo ib yam.
