1. Kev tshuaj xyuas cov hlua hlau
Qhov xwm txheej ntawmof elevator hlau ropesyog ncaj qha ntsig txog kev nyab xeeb ntawm cov cuab yeej siv thiab cov neeg caij tsheb, thiab yuav tsum tau them nyiaj txaus rau kev soj ntsuam xyuas thiab ua tib zoo tshuaj xyuas yuav tsum tau ua thaum ua haujlwm. Cov ntsiab lus tshuaj xyuas yog: (1) Tshawb xyuas tus lej, qhov chaw thiab qhov ntev ntawm cov xov hlau tawg. Cov hlau tawg; (2) Txoj kab uas hla ntawm lub elevator hlau hlua ua nyias. Ntxiv nrog rau kev tshuaj xyuas qhov muag, tsis tu ncua siv vernier caliper los ntsuas cov hlua txoj kab uas hla thiab hnav; (3) Tshawb xyuas qhov nro ntawm lub elevator hlau hlua. Qhov sib txawv ntawm qhov nro ntawm txhua txoj hlua yuav tsum tsis pub tshaj 5%; (4) Lub lubrication, tu thiab corrosion ntawm cov hlua hlau; (5) Qhov xwm txheej ntawm txoj hlua lub taub hau thiab nws cov kev sib xyaw ua ke, thiab seb puas muaj lwm yam txawv txav ntawm tag nrho qhov ntev, xws li txawv txav elongation hloov ntawm txoj hlua, thiab lwm yam.
2. Hnav thiab deformation ntawm steel hlau hlua
Raws li kev paub dhau los, nws yog qhov tsis tshua muaj rau lub elevator hlau ropes dheev tawg nyob rau hauv ib txwm ua haujlwm. Kev puas tsuaj feem ntau tshwm sim los ntawm kev hnav, khoov qaug zog, xeb lossis raug mob thaum lub sijhawm ua haujlwm ntev. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tshuaj xyuas ntawm hnav thiab corrosion. Hnav muaj xws li hnav ntawm qhov chaw ntawm cov hlua hlau, nruab nrab ntawm cov hlua, thiab ntawm cov xov hlau.
3. Corrosion of elevator hlau hlua
Of elevator hlau ropes yuav xeb thaum siv, lawv cov khoom siv kho mob yuav txo qis, txoj kab uas hla ntawm cov hlau yuav ua thinner, thiab cov strands yuav loosen, uas ua rau nkig puas. Qhov kev so zoo li no yog qhov "avalanche" so, uas yog qhov txaus ntshai tshaj li cov hlau tawg lossis hnav. Kev saib xyuas tshwj xeeb yuav tsum tau them rau txhua qhov corrosion ntawm steel hlau hlua thaum tu. Yuav tsum tau ua tib zoo soj ntsuam. Yog tias pom tias qhov corrosion yog qhov hnyav thiab tau tsim cov pits lossis cov hlau hlau sab nraud ntawm txoj hlua hlua khi, nws yuav tsum tau hloov tsis hais cov hlau tawg lossis cov hlua txoj kab uas hla. "Liab roj" qhia tau hais tias tsis muaj roj nyob rau hauv txoj hlua core thiab muaj xeb nyob rau hauv, uas yuav tsum tau them sai sai rau. Yog tias tsim nyog, koj tuaj yeem txiav txoj hlua kawg txhawm rau txheeb xyuas qhov xeb sab hauv ntawm cov hlua hlau. Txoj hauv kev los tiv thaiv cov hlua hlau hlau los ntawm xeb yog siv cov roj ntawm cov hlua rau kev tiv thaiv.
