1. phab ntsa thickness check
Cov cuab yeej siv rau kev tshuaj xyuas phab ntsa tuab yog tsuas yog micrometer. Thaum kuaj xyuas, siv micrometer los ntsuas cov phab ntsa tuab ntawm galvanized square yeeb nkab ib los ntawm ib qho. Ua ntej kuaj xyuas, ua ntej txheeb xyuas seb daim ntawv pov thawj ntawm kev sib haum xeeb ntawm micrometer puas nyob rau lub sijhawm siv tau, thiab ntsuas seb lub micrometer puas ua raws li xoom txoj hauj lwm, seb qhov kev sib hloov yog hloov tau, thiab ntsuas qhov saum npoo yuav tsum tsis muaj khawb thiab xeb, thiab nws tuaj yeem siv tsuas yog tom qab nws tsim nyog. Thaum kuaj xyuas, sab laug tes tuav micrometer bracket, nrog rau sab tes xis los tig lub log excitation, tus pas nrig lo lo ntxhuav yuav tsum coincident nrog txoj kab uas hla ntawm qhov ntsuas qhov ntsuas, qhov kawg ntsuas yuav tsum tsis pub tsawg tshaj 6 lub ntsiab lus, pom tias phab ntsa tuab. yog tsis tsim nyog, yuav tsum tau cim.
2. Sab nraud txoj kab uas hla thiab ellipticity check
Sab nraud txoj kab uas hla thiab ellipticity xyuas cov cuab yeej siv feem ntau yog calipers, vernier calipers. Thaum kuaj xyuas, ntsuas cov kab sab nraud ntawm galvanized square raj ib los ntawm ib qho uas tsim nyog calipers. Ua ntej kev tshuaj ntsuam xyuas, thawj zaug xyuas seb daim ntawv pov thawj ntawm kev ua raws li daim npav ntsuas lub sijhawm siv tau, thiab vernier calipers calibrate daim npav ntsuas siv, ntsuas qhov chaw seb puas muaj khawb thiab xeb, tsim nyog ua ntej siv. Thaum kuaj xyuas, daim npav daim npav yuav tsum yog nyob rau ntawm lub axis ntawm galvanized square tube, galvanized square raj maj mam tig, ntsuas qhov cross-section qhov twg cov kab sab nraud pom tias loj lossis me, yuav tsum tau cim.
3. Kev kuaj xyuas ntev
Galvanized square tube ntev xyuas cov cuab yeej siv feem ntau yog daim kab xev hlau, ntsuas qhov ntev, daim kab xev "O" taw tes ua ke nrog ib qho kawg ntawm galvanized square tube, thiab tom qab ntawd nruj daim kab xev, kom ib sab ntawm daim kab xev ntsuas ze rau ntawm qhov chaw. ntawm galvanized square raj, galvanized square raj ntawm lwm kawg ntawm daim kab xev ntev yog qhov ntev ntawm galvanized square raj.
4. Curvature check ntawm galvanized square raj
Khoov kos ntawm galvanized square yeeb nkab yog tsuas yog los xyuas tag nrho qhov ntev ntawm galvanized square yeeb nkab khoov, khoov ib meter, cov cuab yeej siv feem ntau yog qib kav, plug kav thiab nuv ntses kab. Ntsuas tag nrho cov bending degree ntawm galvanized square yeeb nkab, siv cov ntses kab los ua ke nrog ib kawg ntawm galvanized square yeeb nkab, thiab ces rub cov ntses kab kom nruj, kom ib sab ntawm cov ntses kab yog nyob ze rau saum npoo ntawm galvanized square yeeb nkab. , thiab tom qab ntawd siv tus pas ntsuas qhov kev ncua deb ntawm qhov chaw ntawm cov yeeb nkab square galvanized thiab qhov sib txawv ntawm cov ntses kab, uas yog, tag nrho ntev ntawm galvanized square yeeb nkab dabtsi yog khoov degree.
