Yuav ua li cas txiav txim siab qhov kawg ntawm lub log hnav ntawm lub khw muag khoom lag luam?

Txhawm rau txiav txim siab lub log hnav rau ntawm lub log tsheb loj, tshawb xyuas cov log raws li cov tsos ntawm tsos, muaj nuj nqi, thiab cov ntsiab lus. Qhia kom sai thiab hloov cov teeb meem los xyuas kom muaj kev nyab xeeb thiab kev siv khoom zoo:

I. Nruag Soj Ntsuam

Log Ntuav Hnav: Uniform indentations tshaj li 1mm, hauv zos chipping lossis tawg, lossis fuzzing, lossis chriPing qhia qhov hnyav.

Deformation thiab eccentricity: yog lub log yog pom zoo wobbly, tawm ntawm puag ncig, lossis eccentric thaum koj nqa tau yooj yim ua rau lub laub rau jam lossis veer.

Stain: accitulation ntawm cov roj, av, thiab xuab zeb hauv cov khoob ntawm lub log ntawm lub log yuav qhia kev laus laus. Discoloration lossis brittleness ntawm qhov chaw taw qhia corrosion thiab yuav tsum hloov.

Ii. Kev Kuaj Ua Haujlwm

Thawb kev tawm tsam: Yog thawb ntawm ib qho chaw tiaj tiaj yog qhov nyuaj lossis ua rau lub suab tsis muaj zog, nws tuaj yeem qhia cov log qev lossis ntau dua cov log sib txhuam.

Kev hloov kho lub log tsheb thoob plaws kauj ruam dhau los, tsis tuaj yeem rov qab mus rau qhov chaw, lossis "xauv," feem ntau yog vim kev puas tsuaj lossis kev coj tsis ncaj lossis tsis sib luag.

Thauj - bearing stability: yog lub log tog kev ruaj khov: nws qhia tau ntau yam kev phom sij thiab ua kom muaj kev phom sij txaus ntshai.

III. Cov ncauj lus kom ntxaws

Xev qag: manually co lub log. Yog tias muaj qhov pom tau ua si, xeb, lossis grooves, hloov nws kom sai.

Tus nres nres (yog tias muaj): Yog tias muaj lub log nraub qaum tseem hloov tom qab braking lossis pedal yog xoob, kos kom haum ntawm lub log thiab lub ncoo nres.

IV. Nqaum kho

Kev hnav me me (khawb me me, ua haujlwm ib txwm): huv si thiab saib, thiab tsis hloov rau tam sim no.

Kev hnav me me (dents hauv zos, tso me me thaum thawb): Npaj los hloov, thiab txwv siv rau lub teeb ntim.

Kev hnav hnyav (deformation, tsis muaj suab nrov, tilting hauv qab thauj khoom): tam sim ntawd tshem tawm los ntawm kev pabcuam thiab hloov.

SecondMarets tau pom zoo los tsim kev tshuaj xyuas txhua lub lim tiam, tsom mus rau qhov siab {}}}}}}} Cov khoom tshiab thiab thaj chaw cia). Los ntawm "kev tshuaj xyuas, kev sim, thiab tshuaj xyuas," lawv tuaj yeem ntsuas qhov kev hnav zoo sai sai thiab ua kom muaj kev nyab xeeb thiab du ntawm Trolley.
