UHlelo Lokuphefumula nothuli lohlelo lokususa ngothuli lomshini wokuqhuma kwesihlabathi luyisihluthulelo sokusetshenziswa kwemishini, ngakho-ke ngaphambi kokuba kusetshenziswe imishini, uhlelo lokususa uthuli kufanele lushintshwe futhi luthuthukiswe ukufeza izidingo ezigcwele ngemishini.
Ngemuva kokuhlaziywa, kwenziwa intuthuko elandelayo ohlelweni lwangempela:
Okokuqala, shintsha ukuqeda okuphansi okuphansi kuya ekuqedeni okuphezulu.
Okwesibili, khetha kabusha i-fan, ukubala ububanzi be-duct yomoya, ukuze ivolumu yomoya, ukucindezela komoya kanye nejubane lomoya ukuzivumelanisa nezidingo zokusebenza kohlelo. Engeza umnyango we-butterffly oguqukayo ngaphambi kokungena kwe-fan.
Abathathu, baphinde bakhethe umqoqi wothuli, ukuze bahambisane nevolumu yomoya yamanje nezidingo zokususa uthuli.
Umshini we-sandblasting irabha elingaphakathi, ukunciphisa umsindo
Uhlelo lokususa uthuli oluhlelwe kabusha luboniswa esilinganisweni. Inqubo yayo yokusebenza yilena: Ukugeleza komoya okunezinhlayiya zesihlabathi ezikhishwe yi-nozzle, umthelela endaweni yokusebenza, ukuphindeka ngemuva kwezinhlayiya zama-coarse, futhi izinhlayiya ezincane zitholwe yi-acter vent engenhla, ngemuva kokukhishwa komoya: Ukuhlanzwa komoya ngumlandeli emkhathini. Ngemuva kokuthuthuka ngokuya ngohlelo lokuklama okungenhla. Imvelo yokusebenza ezungeze umshini weSandblasting ithuthuka kakhulu ukufeza inhloso yokuthuthuka.
