Dab tsi yog lub hom phiaj ntawm txoj kev tsheb nqaj hlau?
Nov 07, 2025
Rail sab xub pwgraug nrum nyob rau hauv cov qhob kev tsheb ciav hlau los kho cov clips me me. Muaj ob hom kev tsheb ciav hlau muaj, cov cam -} pa {2} ntawm weld {2} ntawm cov uas siv rau kev txhim kho ntawm kev sib tw tsuj.
Lub xub pwg sib xyaw ua lub ntsej muag txuas ntawm txoj kev tsheb nqaj hlau yog nias hauv cov chaw pw hauv tsev thiab ua haujlwm ua ke nrog cov clip kom nrawm nrawm. Qhov cam khwb cia hauv xub pwg yog ua los ntawm casting los ntawm cov cam khwb cia los ntawm cov hlau, xws li, GIS G5502 (xyoo 16293 (1985) lossis BS EN 1563 (1997).

Lub hom phiaj ntawm Ris pwg
Lub hom phiaj ntawm kev tsheb nqaj hlau yogKev ruaj ntseg thiab txhawb nqa kev tsheb nqaj hlaunyob rau hauv ib txoj kev nrawm system. Nws pabcuam ua cov kab ke tseem ceeb uas tuav kev tsheb ciav hlau, muab cov haujlwm txuas ntxiv ntawm cov clips uas tuav txoj kev tsheb nqaj hlau mus rau hauv boundplate lossis pw tsaug zog.
Cov haujlwm tshwj xeeb ntawm kev tsheb nqaj hlau
- Fastening:Tus ntsia xub pwg ua haujlwm nrog elastic kev tsheb ciav hlau (zoo li e - clips) kom nrawm nrawm rau lub hauv paus lossis pw tsaug zog.
- Txhawb Kev Txhawb Ib Tom Qab:Nws tiv thaiv kev tsheb ciav hlau los mus rau kev txav mus los sab nraud, uas yog qhov tseem ceeb rau kev nyab xeeb thiab tiv thaiv kev dag.
- Stability:Los ntawm kev muab lub hauv paus ruaj khov thiab muaj kev nyab xeeb, nws ua kom cov tsheb ciav hlau tseem nyob ruaj khov thiab hauv qhov tseeb.
- Ntsaws faib:Nws pab faib cov kev thauj khoom los ntawm cov qauv hauv qab, xws li cov vaj tsev ua vaj tse lossis cov ntoo ua kom tsawg, uas txo kev ntxhov siab thiab hnav.
- Qhov ruaj khov:Tsim los ntawm cov khoom siv ruaj li cov hlau cam khwb cia hlau, nws yog tsim los tiv thaiv cov mob hnyav ntawm kev siv tsheb ciav hlau.
Nrum - hauv kev tsheb nqaj hlau
Tuslub xub pwgRaws li cov lus pom ntawm txoj kev tsheb nqaj hlau yog nias hauv cov chaw pw hauv vaj tse thiab ua haujlwm ua ke nrog cov clip kom nrawm nrawm. Qhov cam khwb cia hauv xub pwg yog ua los ntawm casting los ntawm cov cam khwb cia los ntawm cov hlau, xws li, GIS G5502 (xyoo 16293 (1985) lossis BS EN 1563 (1997).
