Kev hloov kho ib puag ncig thiab lub neej txuas ntxiv thev naus laus zis rau lub caij nplooj ntoo hlav
- Vim li cas Elastic Strips hauv Alpine Cheeb Tsam ({56N) Siv 60si2MN Hlau, thiab kev sim tsawg-kub nyuaj?
Decient 60si2mn steel muaj lub zog tsawg dua los yog sib npaug rau 15j ntawm - 40 degree, nquag mus rau brittle backstre; 60si2MNCRV Hlau nrog CR thiab V ntxiv muaj kev cuam tshuam lub zog loj dua los yog sib npaug rau 30J, ob npaug ntawm qis - kub nruj. Kuaj: Noj Elastic Sawb kuaj xyuas rau- Txoj Cai Charpy cuam tshuam kom ntseeg tau lub zog ua tau raws cov qauv; Ua cov qes qis-kub los ntawm kev twv twv, yuav tsum tsis txhob tawg tom qab 15℃khoov. Thaum lub sij hawm installation, tswj qhov sib txawv ntawm cov kab sib txawv ntawm txoj hlua ntawm 0.1-0.2mm kom tsis txhob jamming vim tsawg-kub shrinkage; Txheeb xyuas txoj kev taug kev tshiab ua ntej txhua lub caij ntuj no, hloov tam sim ntawd yog tias muaj cov kab nrib pleb.
- Vim li cas Elceastic Strips nyob rau hauv ntug hiav txwv cheeb tsam yuav tsum tau DACROMET +}} dip galvosizing?
Kub - dip galvanizing tiv taus ntsev txau rau 48 teev, thaum dacromet + teev cia rau 500 teev. Nqaum dej hiav txwv Ntses cov chaw ua kom yooj yim ua rau yooj yim kub - dip galvanizing txheej los tev tawm. Kuaj: Qhov chaw Elastic Strips nyob rau hauv ib 5% Sodium chloride ntsev txau, xav tau coure corrosion tsawg dua los yog sib npaug rau 5%; Siv tus ntoo khaub lig - Txiav kev ntsuam xyuas kom kuaj adhesion, kom tsis txhob txheej picking tom qab txiav. Tom qab kev teeb tsa, txheeb xyuas Elastic Sawb Ruav txhua 2 xyoos, kho cov xeb hauv zos nrog cov tshuaj tiv thaiv tshwj xeeb los tiv thaiv corrosion kis.
- Elastic strips nyob rau hauv high - kub thaj tsam (qhov cub kub (qhov cub kub 60℃nyob rau lub caij ntuj sov) muaj kev pab cuam elastic sai. Yuav ua li cas qeeb nws los ntawm kev teeb tsa kev hloov kho?
Kev kub siab txo qis loj modulus ntawm elastic strips los ntawm 10 - 15%. Thaum lub sij hawm installast- compression ntawm elastic strips los ntawm 0.5}} 10}}} kub tsis muaj kev poob siab. Lub caij no, siv cov roj kub siab (kub tsis kam 150 degree) mus rau thaj chaw tiv tauj ntawm txoj kab sib raug zoo thiab cov nqaj hlau kom txo tau kev sib txhuam thiab hnav. Kuaj-xeem Elastic Strips Nrog tus Elastic Tester txhua lub quarter, hloov yog tias txoj kev ua kom tiav clamping quab yuam raws cov qauv thiab tiv thaiv kev daws teeb meem.
- Dab tsi yog kev sib raug zoo ntawm pre - deformation ntawm elastic strips thaum lub neej, thiab dab tsi teeb meem ua ntej {1} deformation ua rau?
Pre6 - deformation ntawm anricast strips yuav tsum yog nyob rau hauv ntau yam: 8 {}} 10mm rau hom ⅱ. Nrog tsim nyog ua ntej pre - deformation, elastic strips dais zog uayees, nrog lub zog qaug zog tshaj 2 lab mus; Ntau dhau lawm ua ntej- deformation (piv txwv li ntau dua 12 hli rau hom deformation thiab tshaj 30% clamping yuam kev poob tom qab ntev- siv; Tsis txaus ua ntej - deformation (piv txwv li, tsawg dua 6 hli rau hom elasticity, uas ua rau muaj kev tiv thaiv tsis txaus thiab cov tsheb ciav hlau yooj yim. Siv cov cuab yeej tshwj xeeb ntsuas los ntsuas ua ntej deformation thaum lub sijhawm teeb tsa, rov kho dua yog qhov kev cuam tshuam ntau dua ± 0.5mm.
- Thaum cov kab nrib pleb tshwm sim ntawm txoj hlua khi ntawm kev siv, yuav ua li cas thiaj txiav txim yog tias lawv cuam tshuam rau kev siv, thiab txoj kev sib txawv li cas?
Tawg nrog ntev<3mm and not extending to key stress areas (e.g., bends) can continue to be used but require monthly follow-up checks; cracks with length 3-5mm or extending to stress areas require immediate replacement to prevent crack expansion and elastic strip fracture. During replacement, new elastic strips must match the original model; test clamping force after installation to ensure compliance. Conduct failure analysis on replaced cracked elastic strips; if material issues are identified, trace the same batch of elastic strips for sampling to prevent batch failure.
