1. Yuav ua li cas helical caij nplooj ntoos hlav diameters cuam tshuam lawv kev ua tau zoo nyob rau hauv freight railways?
Cov kab loj dua helical springs (35-40mm) faib cov khoom thauj zoo dua, tiv thaiv sagging nyob rau hauv hnyav qag. Cov kab me me (25-30mm) yog siv rau kev thauj khoom sib dua, ntsuas lub zog thiab qhov hnyav.
2. Dab tsi ua rau cov khoom sib xyaw ua ke zoo tshaj plaws rau lub teeb tsheb ciav hlau piv rau cov hlau?
Composite springs yog 30-40% sib zog dua hlau, txhim kho zog efficiency nyob rau hauv lub teeb rail. Lawv kuj txo qis kev vibration hloov, txhim kho cov neeg caij tsheb kev nplij siab, thaum tseem tiv taus qhov nruab nrab ntawm cov kev khiav tsheb ciav hlau.
3. Yuav ua li cas lub caij nplooj ntoos hlav txhav kev ntsuam xyuas txawv rau cov neeg caij tsheb thiab freight rail daim ntaub ntawv?
Cov neeg caij tsheb ciav hlau muaj qhov qis qis (mob caij) nrog kev ntsuas ntawm 50-100 N / mm, thaum cov khoom thauj khoom thauj khoom muaj zog (100-150 N / mm) txhawm rau tswj cov khoom hnyav thiab tswj kev ruaj ntseg.
4. Cov kev hloov pauv loj npaum li cas muaj nyob hauv cov nplooj hlav rau nqaim- ntsuas kev ntsuas thiab tus qauv- ntsuas kev tsheb ciav hlau?
Nplooj springs rau nqaim- ntsuas txoj kev tsheb ciav hlau luv dua (1.2–1.5m) thiab nyias kom haum rau qhov chaw txwv, thaum tus qauv- ntsuas cov nplooj springs ntev (1.8–2.0m) thiab tuab dua los faib cov tsheb ciav hlau dav dua.
5. Yuav ua li cas stainless hlau springs ua nyob rau hauv txias huab cua piv rau carbon steel?
Stainless hlau springs khaws tau yooj yim nyob rau hauv sub-zero kub (-40 degree), tsis txhob nkig puas. Cov pa roj carbon steel springs tuaj yeem ua rau cov huab cua txias, nce hnav ntawm ob qho tib si springs thiab rails.
