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 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 pamwamba ndi kuyeretsa kosavuta (pamanja sandpaper kapena burashi) kuyeretsa kwa workpiece, ndi njira yowonetsera yofananitsa ❖ kuyanika, moyo ukhoza kukhala 4-5. 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 munjira zonse zoyeretsera pamwamba, njira yopangira mchenga imakhala yokwanira, pansi, yochulukirapo, yochulukirapo, 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, mchenga wa m'nyanja, 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 bwino, kotero kusintha kutopa kwa workpiece, kuonjezera zomatira pakati pa izo ndi ❖ kuyanika, kutalikitsa kulimba kwa filimuyo, komanso yabwino otaya utoto ndi kukongoletsa.
