Roj Hmab Ntsaws RuajPab ib qho haujlwm tseem ceeb hauv kev lag luam khoom siv, tseem xau dej feem ntau cov cuab yeej ua haujlwm ntawm cov neeg ua haujlwm. Kev kuaj xyuas raws sijhawm thiab kho cov roj hmab foob to tsuas yog ua kom cov khoom siv phom sij zoo, tab sis tseem muaj kev nyab xeeb kev nyab xeeb thiab kev lag luam poob peev los ntawm kev xau dej. Kab lus no yuav dhau ntawm txoj kev kuaj mob thiab kho kom zoo rau cov roj hmab ntim xau hauv qhov tob, cia koj daws cov teeb meem uas muaj kev cuam tshuam sai sai.
1. Kev kuaj mob ntawm cov roj hmab kaw lus xau
(I) Saib xyuas qhov chaw thiab cov duab ntawm cov to
Zoo li qub xau: Yog tias cov cuab yeej xau thaum nyob ruaj ruaj, nws yuav yog vim faulty boob uas zig installation, lub zeem muag tsis yog, lossis ntim cov flaws. Kuaj seb puas yog lub foob yog tag nrho cov cim nyob rau hauv lub tshuab sib tsoo thiab seb muaj kev distortion lossis deformation.
Dynamic toastage: to thaum lub sijhawm ua haujlwm tuaj yeem tshwm sim los ntawm kev sib txhuam siab ntawm lub foob thiab cov khoom txav, uas ua rau lub foob hnav lossis cuam tshuam. Txheeb xyuas lub foob saum npoo rau cov cim ntawm kev hnav hnyav thiab tsis tsim nyog sib txawv ntawm cov txav.
(II) Kuaj xyuas lub cev ntawm lub foob
Cov tsos tshuaj xyuas: khij lub foob lub foob saum npoo rau cov kab nrib pleb, npuaj, nthuav dav, lossis tawv tawv. Cov no tuaj yeem tshwm sim los ntawm kev laus, tshuaj lom corrosion, lossis ua txhaum ntau dhau los compression.
Elasticity ntsuam xyuas: Nias lub foob muag nrog koj txhais tes kom pom tias nws muaj elasticity zoo. Yog hais tias lub foob plam, qhov no tuaj yeem yog vim muaj ib puag ncig kub tsawg lossis cov ntaub ntawv tsis zoo.
(III) Txheeb xyuas qhov kev teeb tsa ib puag ncig thiab cov xwm txheej
Qhov kub thiab txias thiab siab: txiav txim siab seb cov cuab yeej ua haujlwm kub thiab kev ntsuas tshaj lub foob kev ua siab ntev. Yog tias qhov ntsuas kub lossis lub siab yog ntau dhau, lub foob yuav ploj mus rau kev nthuav dav los yog dhau-compression.
Tshuaj Nruab Nrab: txiav txim siab seb lub foob yog sib xws nrog cov tshuaj nruab nrab hauv cov khoom siv. Yog hais tias cov khoom ntim khoom siv nrog cov tshuaj lom neeg, lub foob yuav swell, yaj, lossis ua tsis taus.
Ii. Kev Kho Txoj Kev Siv Rau Cov Roj Hmab Faj
(I) Hloov lub foob
Yog hais tias lub foob yog tawg ntau yam lossis hnub nyoog, qhov kev xaiv ncaj tshaj plaws yog los hloov nws nrog ib qho tshiab. Nws yog qhov tseem ceeb los xaiv cov khoom ntim uas tsim nyog thiab cov lus qhia tshwj xeeb kom paub meej tias cov khoom siv ua haujlwm thiab xov xwm.
(II) Siv cov ntsaws ruaj ruaj
Nyob rau hauv xyoo tsis ntev los no, kev kho tus kheej kev kho tshuab sib cog lus tau txais cov koob meej. Piv txwv li, kho tus kheej kho cov cwj pwm zoo li qub muaj kev txhaj tshuaj kho. Thaum muaj xau dej nyob ntawm thaj chaw puas thiab tsis ntev ua, rov ua dua cov khoom sib khi. Qhov kev foob no tsis yog tsuas yog kho nws tus kheej, tab sis nws tseem nthuav nws txoj kev pabcuam lub neej thiab kev ntseeg tau.
(III) Ua kom zoo ua kom cov neeg foob
Kho cov nyiaj ua ke
Ntxiv cov khoom siv tiv thaiv: Txuas ib lub nplhaib khaws cia rau sab nraud ntawm lub foob yuav ua kom nws tsis muaj kev puas tsuaj thaum lub sijhawm teeb tsa lossis kev ua haujlwm.
(Iv) kev kho deg thiab txheej
Lub foob nto tuaj yeem kho tau lossis siv kom txhim kho kev hnav thiab tshuaj lom neeg tiv taus. Piv txwv li, thov ib qho kev tiv thaiv anti-ultraviolet lossis paraffin txheej tuaj yeem txwv qhov cuam tshuam ntawm cov khoom sab nraud ntawm cov foob.
(V) kev saib xyuas thiab tshuaj xyuas
Kev soj ntsuam tsis tu ncua: Nws tau qhia tias cov roj hmab ntsaws ruaj ruaj txhawm rau tshawb xyuas cov kev phom sij thaum ntxov.
Kev tu thiab kev txij nkawm: Huv lub foob lub pob saum npoo ua ntu zus los tiv thaiv kev xeb los ntawm av thiab paug.
III. Cov Ntaub Ntawv Kev Ntsuam Xyuas thiab Cov Lus Qhia
Rooj plaub 1: qhov kub tsawg xau
Lub Hoobkas cov khoom siv hydraulic tau tsim kev xau nyob rau hauv ib puag ncig muaj cua tsawg-tsawg. Tom qab kuaj xyuas, nws tau pom tias cov roj hmab o-zoo li cov roj hmab poob yooj yim ntawm qhov kub tsawg. Lo lus teb yog hloov cov khoom ntim nrog cov khoom siv txias dua thiab sov cov khoom siv ua ntej pib ua ntej lub foob muaj qhov hloov tau zoo ntawm qhov chaw kub.
Rooj plaub 2: Dynamic to
Ib qho khoom siv neeg kho tshuab tau paub txog kev tsis muaj zog thaum ua haujlwm. Tom qab kev tshawb nrhiav, nws tau pom tias kev hnav khaub ncaws tau tshwm sim los ntawm kev sib txhuam siab ntawm lub foob thiab cov khoom sib hloov. Txoj kev daws teeb meem yog siv cov khoom siv cov hnav ntau ntxiv thiab siv roj nplua nyeem thiab siv lub roj nplaum rau lub foob nto kom txo kev sib txhuam.
IV. Lub ntsiab
Txawm hais tias Bastage ntawm cov roj hmab ntsaws ruaj ruaj yog qhov daws teeb meem, nws tuaj yeem nrawm daws thiab lub foob ua haujlwm lub neej ntev siv cov kev kuaj mob thiab cov txuj ci kho tau zoo. Hauv cov ntawv thov siv, nws tau pom zoo kom xaiv cov txheej txheem tsim nyog kho lossis hloov cov khoom siv uas haum rau ntawm cov khoom siv ua haujlwm thiab kev siv cov xwm txheej foob. Nyob rau tib lub sijhawm, kev saib xyuas tsis tu ncua, kev kuaj xyuas yog cov kauj ruam tseem ceeb rau kev tiv thaiv kev xau, uas tuaj yeem tshem tawm cov khoom siv poob qis thiab poob nyiaj tsis tau.
Yog tias koj muaj lus nug txog kev kuaj mob thiab kho cov hlua roj hmab, lossis yog tias koj xav tau kev pab ntxiv, thov hu rau peb. Peb yuav muab cov kev daws teeb meem los pab koj kom koj kov yeej cov khoom siv xau thaum ua haujlwm zoo thiab kev nyab xeeb ntawm cov cuab yeej siv.
