1. Yuav ua li cas steel railway springs txawv los ntawm composite ones nyob rau hauv cov nqe lus ntawm load-bearing muaj peev xwm? Steel railway springs feem ntau muaj ntau dua load-cov kabmob muaj peev xwm, feem ntau tshaj 50 kN, ua rau lawv haum rau cov khoom thauj hnyav. Composite springs, thaum sib dua, feem ntau tuav qis qis (txog 30 kN) thiab nyiam rau cov neeg caij tsheb uas qhov hnyav txo qhov tseem ceeb.
2. Yuav ua li cas distinguishes lub helical caij nplooj ntoos hlav los ntawm ib tug nplooj caij nplooj ntoos hlav nyob rau hauv daim ntawv thov kev tsheb ciav hlau?
Helical springs siv lub coiled tsim uas muab kev sib xyaw ua ke thiab kev co zoo heev, zoo tagnrho rau cov neeg caij tsheb ciav hlau. Nplooj springs muaj xws li stacked hlau daim hlau, muab siab rigidity thiab load tis, ua rau lawv zoo dua haum rau freight railways nrog hnyav qag loads.
3. Cov khoom siv caij nplooj ntoos hlav sib txawv li cas (piv txwv li, siab- carbon steel vs. stainless hlau) ua li cas nyob rau hauv ib puag ncig ntug hiav txwv?
Stainless hlau springs tiv thaiv corrosion los ntawm dej ntsev thiab av noo nyob rau hauv ntug hiav txwv dej, kav 20-30 xyoo. High- carbon steel springs, txawm tias muaj zog dua, yuav tsum tau siv tshuaj tiv thaiv ntau zaus thiab yuav tsum tau hloov txhua 10-15 xyoo hauv tib qhov chaw.
4. Cov kev hloov pauv loj npaum li cas nyob rau hauv txoj kev tsheb ciav hlau rau 50kg/m vs . 75kg/m rails?
Springs rau 75kg / m rails yog loj (ntev coils, thicker hlau) los tuav ntau dua nro thiab loads, nrog diameters li ntawm 30-40mm. Cov rau 50kg / m rails yog me me (20-25mm txoj kab uas hla) thiab sib dua, optimized rau qis zog.
5. Yuav ua li cas compression springs txawv ntawm extension springs nyob rau hauv railway nres systems?
Compression springs yog siv nyob rau hauv lub tshuab nres kom nqus cov kev cuam tshuam thaum lub sij hawm braking, thaum txuas ntxiv springs muab lub zog kom thim rov qab nres nres. Compression springs muaj cov coils nruj dua rau kev poob siab, whereas extension springs muaj looser coils kom yooj yim dua.
