Muaj peb txoj hauv kev los txuas cov kav dej galvanized:
1. Rolling groove kev twb kev txuas
Yob groove weld cracking:
① Sib tsoo cov vuam tuav ntawm cov phab ntsa sab hauv ntawm lub siab zawj ntawm cov yeeb nkab qhov ncauj kom txo tau qhov tsis kam ntawm qhov zawj dov;
② Kho cov axis ntawm cov yeeb nkab steel thiab cov khoom siv dov grooving, thiab xav tau cov yeeb nkab steel thiab cov khoom siv dov grooving kom qib;
③ Kho qhov nrawm nrawm. Lub sij hawm grooving yuav tsum tsis txhob tshaj lub sij hawm teev thiab siv zog sib npaug thiab maj mam.
Rolling groove steel yeeb nkab tawg:
① Sib tsoo cov vuam tuav ntawm cov phab ntsa sab hauv ntawm lub siab zawj ntawm cov yeeb nkab steel lub qhov ncauj kom txo tau qhov rolling groove tsis kam;
② Kho cov axis ntawm cov yeeb nkab steel thiab cov khoom siv dov kom ntseeg tau tias cov yeeb nkab steel thiab cov khoom siv dov grooving yog qib;
③ Kho qhov nrawm nrawm. Lub trough ceev yuav tsum tsis txhob tshaj qhov txwv thiab siv zog sib npaug thiab maj mam;
④ Txheeb xyuas qhov dav thiab qauv ntawm cov menyuam txhawb nqa thiab lub siab cov menyuam ntawm cov khoom siv dov grooving kom pom tias muaj qhov tsis sib xws ntawm qhov loj ntawm ob lub chais ua rau tom;
⑤ Siv lub vernier caliper los xyuas seb qhov zawj ntawm cov yeeb nkab steel puas tau teev tseg.
Cov grooves dov los ntawm lub tshuab dov groove yuav tsum ua tau raws li cov hauv qab no:
①Qhov saum npoo ntawm cov yeeb nkab kawg mus rau qhov zawj yuav tsum du, tsis muaj qhov tsis sib xws los yog dov cov cim;
② Qhov nruab nrab ntawm qhov zawj yuav tsum yog concentric nrog cov yeeb nkab phab ntsa, qhov dav thiab qhov tob ntawm qhov zawj yuav tsum ua tau raws li qhov yuav tsum tau ua, thiab xyuas seb tus qauv clamp puas yog;
③ Siv cov roj nplaum rau lub nplhaib sib khi thiab xyuas seb lub nplhaib roj hmab puas puas lawm. Cov roj lubricating yuav tsum tsis txhob siv los ua cov roj nplua nyeem.
2. Kev sib txuas ntawm vuam
① Tom qab galvanized steel yeeb nkab txuas nrog, cov yeeb nkab kawg tsis nyob hauv txoj kab ncaj nraim thiab cov yeeb nkab steel muaj qhov teeb meem oblique qhov ncauj. Nws raug nquahu kom txiav ib feem me me ntawm cov yeeb nkab steel taub hau ua ntej ua haujlwm;
② Tom qab galvanized steel yeeb nkab yog butted, ob lub kav dej tsis txuas nrog nruj, ua rau tsis sib xws ntawm cov vuam sib txuas, thiab cov yeeb nkab steel muaj lub qhov ncauj elliptical vim nws cov laj thawj lossis pob thaum thauj. Nws raug nquahu kom txiav ib feem me me ntawm cov yeeb nkab steel taub hau ua ntej rov nruab. ua cov txheej txheem;
③Tom qab galvanized steel yeeb nkab yeeb nkab lub qhov ncauj yog butted, hlwv tshwm nyob rau hauv cov yeeb nkab qhov ncauj cheeb tsam, uas yog tshwm sim los ntawm technical vim li cas thaum vuam;
④ Muaj cov qog zinc ntawm lub qhov ncauj ntawm cov yeeb nkab, uas ua rau vuam nyuaj thiab hlwv. Yog tias cov qog zinc loj dhau los yog muaj cov hlab ntsha ntau dhau, yuav tsum tau tshem tawm cov qog zinc yooj yim.
3. Threaded kev twb kev txuas
① Cov xov buckle yog buckled randomly: cov yeeb nkab hoop thiab xov buckle tsis tuaj yeem tiv tauj los yog xoob, txiav tawm qhov buckled randomly, thiab rov nruab cov xov;
② Cov yeeb nkab steel thiab cov yeeb nkab hoop xov tsis sib xws thiab tsis tuaj yeem txuas tau. Cov yeeb nkab hoop yuav tsum tau hloov los yog cov khoom siv yuav tsum tau hloov kho kom rov xa xov;
③ Cov yeeb nkab steel yog ploj lawm tom qab threading: ntsuas seb cov phab ntsa thickness ntawm cov yeeb nkab steel puas tuaj yeem ua tau raws li cov qauv tuab ntawm cov yeeb nkab threading.
