Izicelo kanye Nomgomo Wokusebenza Wokuqhunyiswa Kwe-Abrasive

Selokhu ukuqhuma kwaqala ukubonakala cishe ngo-1870, sekuqhubeke iminyaka engaphezu kwekhulu. Njengoba sonke sazi, umbhobho wokuqala oqhumayo wasungulwa yindoda okuthiwa uBenjamin Chew Tilghman. Futhi imibhobho ye-Venturi yavela ngeminyaka yawo-1950s ngokusekelwe kumbono ohambisanayo wesazi sefiziksi sase-Italy u-Giovanni Battista Venturi. Kulesi sihloko, umgomo wokusebenza kanye nokusetshenziswa kokuqhumisa kuzokhulunywa ngakho.

Umgomo Wokusebenza Wokuqhuma

Lapho izisebenzi zisebenzisa imibhobho yokuqhumisa isihlabathi, kusetshenziswa umshini wokucindezela isihlabathi owomile, oxhaswe umoya ocindezelwe. Umoya ocindezelweyo uzodala ingcindezi ethangini lokucindezela lomshini we-sandblasting, ucindezele izinto ezihuqayo ungene epayipini elidluliselayo nge-outlet, bese ujova into ehubhukayo iphume emlonyeni. Izinto eziqhumayo ziyafafazwa ukuze zibhekane nobuso bomsebenzi ukuze kuzuzwe injongo oyifunayo.

Isicelo Blasting

1. Ukuqhuma kusetshenziselwa ukususa ukugqwala nokunye ukungcola ebusweni bomsebenzi ngaphambi kokumboza i-workpiece. Ukuqhuma kungase futhi kufinyelele ubulukhuni obuhlukene ngokushintsha izinto ezilumayo ezinosayizi abahlukene ukuze kuthuthukiswe amandla okubopha phakathi kocwecwe lokusebenza kanye nokunameka.

2. Ukuqhunyiswa kungasetshenziselwa ukuhlanza nokupholisha izindawo ezimahhadlahhadla zokubunjwa kanye nezinto zokusebenza ngemuva kokwelashwa kokushisa. Ukuqhuma kungahlanza zonke izinto ezingcolile ezifana ne-oxide namafutha, kuthuthukise ukushelela kwe-workpiece, futhi kungenza ucezu lokusebenza luveze ukubukeka kwalo kombala wensimbi, omuhle kakhulu.

3. Ukuqhuma kungasiza ukuhlanza i-burr futhi kuhlobise ubuso bezinto zokusebenza. Ukuqhuma kungahlanza ama-burrs amancane ebusweni bezinto zokusebenza, ngisho namakhona ayindilinga amancane lapho kuhlangana khona izinto zokusebenza, ukwenza ingaphezulu lezinto zokusebenza zibe flat.

4. Ukuqhuma kungathuthukisa izakhiwo zemishini yezingxenye. Ngemuva kokuqhunyiswa, kuzoba khona izindawo zokusebenza ezincane ze-concave kanye ne-convex, ezingagcina ukuthambisa ukuze kuthuthukiswe izimo zokugcoba, kunciphise imisindo ngesikhathi sokusebenza, futhi kunwebe impilo yesevisi yomshini.

5. Ukuqhuma kungasetshenziselwa ukwakha indawo eqhumayo. Ukuqhuma kungakhiqiza izindawo ezihlukene, njenge-matte noma ebushelelezi, ezinhlotsheni ezahlukene zezinto, njengensimbi engagqwali, amapulasitiki, i-jade, ukhuni, ingilazi eyisithwathwa, nendwangu.

Uma unentshisekelo kumbobo ebhobozayo eqondile noma i-venturi bore umlomo wokuqhumisa, noma uma ufuna ulwazi olwengeziwe nemininingwane, UNGATHINTA NATHI ngocingo noma ngemeyili kwesokunxele noma SITHUMELE IMEYILI ezansi nekhasi.
