Kumvetsetsa ndondomeko ya mchenga kuphulika makina nzeru yabwino ntchito (imodzi)

Keywords: Junda sandblasting makina sandblasting kabati

Mchenga wophulika makina ogwiritsidwa ntchito, ayenera kumvetsetsa ndondomeko yake, kuti achepetse kulephera kwa zida, kulimbikitsa kugwiritsa ntchito zipangizo zamakono, komanso kuti ogwiritsa ntchito ambiri amvetsetse ntchitoyo, ndondomeko yotsatirayi imayambitsidwa kuti imvetsetse.

Choyamba, pretreatment.

Sandblasting makina kwa workpiece mu kupopera mbewu mankhwalawa, kupopera mbewu mankhwalawa wosanjikiza zoteteza (penti kapena zinthu zina anticorrosive), pamwamba workpiece ayenera mozama mankhwala, wotchedwa pretreatment.

Ubwino wa pretreatment umakhudza kumamatira, mawonekedwe, kukana chinyezi ndi kukana kwa dzimbiri kwa zokutira, chifukwa filimu yopaka bwino (wosanjikiza) imatsatiridwa pamwamba pomwe imatsukidwa bwino.Ngati ntchito yokonzekeratu si yabwino, dzimbiri lidzapitirizabe kufalikira pansi pa zokutira ndikupangitsa kuti chophimbacho chiwonongeke.Pambuyo kuyeretsa bwino pamwamba ndi zosavuta (pamanja sandpaper kapena burashi) kuyeretsa workpiece, ndi kukhudzana njira ❖ kuyanika poyerekeza, moyo ukhoza 4-5 zina.Pali njira zambiri zoyeretsera pamwamba, koma njira yovomerezeka kwambiri ndi: A.zosungunulira kuyeretsa BC dzanja zida D. zida mphamvu

Mwanjira iyi, njira iliyonse imakhala ndi mawonekedwe ake, koma mu njira zonse zoyeretsera pamwamba, njira yopangira mchenga imakhala yokwanira, pansi, yowonjezereka, yowonjezereka, chifukwa chake ndi:

A, sandblasting ndi bwino kuposa njira zina kuyeretsa pamwamba pa workpiece.

B, Palibe njira ina yomwe imakupatsani mwayi wosankha pakati pa milingo inayi yovomerezeka, yovomerezeka mwaukhondo.

Chachiwiri, kuphulika kwa mchenga.

Sandblasting makina ntchito wothinikizidwa mpweya monga mphamvu kupanga mkulu liwiro jekeseni mtengo, kupopera zinthu (mkuwa ore, quartz mchenga, chitsulo mchenga, nyanja yamchenga, silicon carbide, etc.), monga high speed jet ayenera kuthana ndi pamwamba. , mawonekedwe a pamwamba kusintha kwa zigawo zikuluzikulu, chifukwa cha abrasive zotsatira pamwamba pa workpiece ndi kudula, kupeza ukhondo ndi roughness osiyana workpiece pamwamba, kupanga pamwamba pa makina akhoza bwino, kotero kusintha kutopa kwa chogwirira ntchito, kuonjezera kumamatira pakati pa izo ndi zokutira, kutalikitsa kulimba kwa filimuyo, komanso kumapangitsa kuyenda kwa utoto ndi zokongoletsera.
