Mapulogalamu ndi Mfundo Yogwirira Ntchito ya Abrasive Blasting

Chiyambireni kuphulika koyamba cha m'ma 1870, kwachitika zaka zoposa zana. Monga tonse tikudziwira, mphuno yoyamba yotupa idapangidwa ndi bambo wina dzina lake Benjamin Chew Tilghman. Ndipo ma nozzles a Venturi adawonekera m'ma 1950s kutengera lingaliro lothandizira la katswiri wa sayansi ya zaku Italy Giovanni Battista Venturi. M'nkhaniyi, mfundo yogwirira ntchito ndi kugwiritsa ntchito kuphulika zidzakambidwa.

Mfundo Yogwirira Ntchito Yophulika

Ogwira ntchito akamagwiritsa ntchito ma nozzles popukuta mchenga, makina osindikizira-mu sandblasting youma amagwiritsidwa ntchito, omwe amayendetsedwa ndi mpweya woponderezedwa. Mpweya woponderezedwa upanga kukakamiza mu tanki yopondereza ya makina opukutira mchenga, kukanikiza zinthu zowononga mu chitoliro chodutsa potuluka, ndi kubaya zinthu zopumira kuchokera pamphuno. Zida zowononga zimapopera kuti zigwirizane ndi pamwamba pa workpiece kuti akwaniritse cholinga chomwe akufuna.

Kugwiritsa ntchito Blasting

1. Kuphulika kumagwiritsidwa ntchito kuchotsa dzimbiri ndi dothi lina pamtunda wa workpiece musanayambe kuvala workpiece. Kuphulika kungathenso kukhala ndi roughness yosiyana posintha zinthu zonyezimira za makulidwe osiyanasiyana kuti ziwonjezere mphamvu yolumikizirana pakati pa chogwirira ntchito ndi zokutira.

2. Kuphulika kungagwiritsidwe ntchito poyeretsa ndi kupukuta malo ovuta a castings ndi workpieces pambuyo pa chithandizo cha kutentha. Kuphulika kumatha kuyeretsa zonyansa zonse monga okusayidi ndi mafuta, kumapangitsa kuti ntchitoyo ikhale yosalala, komanso imapangitsa kuti ntchitoyo iwonetsere maonekedwe ake amtundu wachitsulo, womwe ndi wokongola kwambiri.

3. Kuphulika kungathandize kuyeretsa burr ndi kukongoletsa pamwamba pa workpieces. Kuphulika kumatha kuyeretsa ting'onoting'ono tating'ono pamwamba pa zogwirira ntchito, ngakhale ngodya zing'onozing'ono zozungulira pamphambano za workpieces, kuti pamwamba pa workpieces ikhale yosalala.

4. Kuphulika kumatha kusintha makina a zigawozo. Pambuyo pophulika, padzakhala malo ang'onoang'ono a concave ndi ma convex a zogwirira ntchito, zomwe zingathe kusunga mafuta kuti apititse patsogolo mafuta, kuchepetsa phokoso panthawi yogwira ntchito, ndikutalikitsa moyo wautumiki wa makina.

5. Kuphulika kungagwiritsidwe ntchito kupanga pamwamba pa kuphulika. Kuphulika kumatha kutulutsa malo osiyanasiyana, monga matte kapena osalala, kuzinthu zamitundu yosiyanasiyana, monga chitsulo chosapanga dzimbiri, mapulasitiki, yade, matabwa, galasi lozizira, ndi nsalu.

Ngati mukufuna mphuno yobowoka yowongoka kapena mphuno yobowoleredwa ndi venturi kuti iphulitsidwe, kapena ngati mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere kapena KUTITUMIZIRANI MAIL pansi pa tsambali.
