Komabe, njira yosonkhanitsira zitsanzo zoyezetsa zamakina izikhala molingana ndi JIS G 0404 Ndime 7.6 (Zotsatira zosonkhanitsira zitsanzo ndi zitsanzo), Mtundu A.
Oyesa chitoliro adzachita mayeso molingana ndi JIS Z 2241 ndipo kulimba kwapang'onopang'ono, kutulutsa mphamvu, komanso kutalika kwake kudzakhala molingana ndi Table 3.
Komabe, kwa machubu osakwana 8 mm wandiweyani, kutalika kwake kudzakhala molingana ndi Table 4 kwa mayesero othamanga pogwiritsa ntchito nambala 12 kapena nambala 5.
Mayeso a Flattening
Kutentha kwa mayeso kuyenera kukhala kutentha kwa chipinda (5 ~ 35 ℃), chitsanzocho chimayikidwa pakati pa mbale ziwiri zophwanyika ndikuponderezedwa mpaka mtunda wa H pakati pa mbale ukhale wocheperapo kusiyana ndi mtengo womwe watchulidwa, pamene chitsanzocho chaphwanyidwa, onani ngati pali mng'alu. pamwamba pa chitsulo chitoliro chitsanzo chipika.
Pamene H=2/3D, onani weld ngati ming'alu.
Pamene H=1/3D, fufuzani ming'alu m'zigawo zina osati msoko wowotcherera.
Chitoliro chachitsulo chosasunthika chikhoza kumasulidwa ku mayesero a flattening, koma ntchito ya chitoliro iyenera kukhala yogwirizana ndi zomwe zilipo.
Kupinda Mayeso
Kugwira mapaipi ndi m'mimba mwake kunja ≤ 40A (48.6mm).
Chojambulacho sichimang'ambika chikapindika pa 90 ° ndi utali wamkati wa 6 kuwirikiza kunja kwake.
Wogula atha kutchula ngodya yopindika ya 180 ndi/kapena utali wozungulira wamkati wa 4 kuchulukitsa kwa chitoliro chakunja.
Kwa mipope yowotcherera yokana, msoko wowotcherera uyenera kukhala pafupifupi 90 ° kuchokera kumtunda kwa bend.
Mayeso a Hydraulic kapena Mayeso Osawononga
Mapaipi onse ayenera kuyesedwa ndi hydraulically kapena kuyesedwa kosawononga.
Komabe, kwa mipope yoyera, izi zimachitika nthawi zambiri musanayambe galvanizing.
Kuyesa kwa hydrotesting kapena kosawononga ndi njira yofunikira pakuwongolera kwapaipi kuti zitsimikizire chitetezo ndi kudalirika kwa mapaipi pakuyika ndikugwiritsa ntchito.
Kuyesedwa kwa Hydrostatic
Ikani kukakamiza kwa hydraulic kuyezetsa kwapamwamba kuposa komwe kutchulidwe ku chitoliro ndikuchigwira kwa masekondi 5 kuti muwone ngati chitolirocho chingapirire kukakamiza komanso ngati kutayikira kumachitika.
