Daim Ntawv Qhia Txog Caij Nplooj Hlav: Yuav ua li cas xaiv cov nplooj ntoos hlav sab xis rau koj cov kev xav tau
1. Dab tsi yog nplooj ntoos hlav?
Lub caij nplooj ntoo hlav yog ib feem ywj, feem ntau sib xyaw ntawm ntau txheej ntawm cov nplooj hlav steel. Nws yog dav siv nyob rau hauv tsheb, cov khoom siv txhua yam, kev tsheb nqaj hlau, thiab lwm thaj teb. Nws lub luag haujlwm tseem ceeb yog los Cushion shocks, nqus kev co, thiab kev thauj khoom.
2. Qhov xwm txheej los txiav txim siab thaum yuav cov nplooj ntoo springs
(1) lub hom phiaj
Cov xwm txheej sib txawv txiav txim siab cov kev qhia tshwj xeeb thiab kev ua tau zoo ntawm nplooj ntoos. Piv txwv li:
Tsheb springs: Siv rau hauv cov tshuab ncua, xav tau kev nqus cov kev nqus zoo thiab cov khoom muaj zog.
Muaj Khoom Nplooj Qis: Yuav tsum muaj siab ntev thiab ruaj khov los tiv thaiv cov kev co ntau zaus nyob hauv ib puag ncig ua haujlwm.
Railway nplooj Springs: Tsim rau cov khoom loj dua thiab txuas ntxiv lub neej.
(2) Xaiv cov khoom siv
Cov nplooj ntoo hlav uas muaj xws li:
65mn (Manganese steel): Siab elasticity thiab hnav tsis kam, haum rau feem ntau cov ntawv thov.
Sup9 (silicon-manganese steel): Lub zog siab dua, zoo tagnrho rau cov ntawv thov hnyav-thauj khoom.
50crvra (Chrome-Vanadium Hlau): Qoob nkees ua kom tsis kam, haum rau kev siv siab thiab ib puag ncig ua hauj lwm ntev.
Stainless hlau: Highly corrosion-resistant, haum rau noo lossis tshuaj ib puag ncig.
(3) Qhov loj me thiab tshwj xeeb
Qhov loj me (ntev, qhov dav, thiab tuab) ntawm nplooj ntoos hlav tawm ncaj qha cuam tshuam nws elasticity thiab thauj-kev muaj peev xwm. Thaum kev yuav khoom, xaiv raws li cov tsis muaj tseeb ntawm koj cov cuab yeej lossis tsheb.
(4) load-coj peev xwm thiab elastic coefficient
Cov khoom siv thauj khoom-cov kabmob tau txiav txim cov nplooj caij nplooj ntoos hlav cov kev txhawb nqa, thaum Elastic Coefficient (mob siab) cuam tshuam nws cov nyhuv cushioning. Feem ntau, cov thauj khoom ntau dua, qhov ntau dua qhov yuav tsum muaj txhav.
(5) Ua Tshuab
Cov nplooj ntawv zoo tshaj plaws feem ntau yauv ua cov txheej txheem hauv qab no los txhim kho kev ua tau zoo thiab cov khoom siv nyiaj ruaj khov:
Kev Kho Cua Sov: Txhim kho lub hardness thiab tawv, lub neej pabcuam kev pabcuam.
Tua puab tsaig: Txo cov kev ntxhov siab sab hauv thiab txhim kho kev ua kom rog tsis kam.
Nto tawm tsam kho corrosion: Suav nrog cov khoom siv hluav taws xob, tshuaj tsuag, lossis kub-dip galvanizing kom tiv thaiv xeb.
(6) Hom thiab Chaw Tsim Tshuaj
Xaiv cov tshuab luam ntawv nrov kom ntseeg tau cov khoom kom zoo thiab kev pab cuam zoo tom qab.
3. Kev yuav cov kev yuav
Kev muag khoom ncaj qha los ntawm cov tuam ntxhab: Tus nqi qis dua, haum rau kev yuav khoom loj-teev.
Tus Neeg Saib Xyuas: Muab ntau yam specifications, zoo tagnrho rau me- thiab nruab nrab-nplai kev yuav khoom.
E-Indmerce Platforms: Xws li Alibaba thiab JD.com, haum rau me-batch lossis ib tus neeg yuav khoom.
