Enqubweni yokusebenzisa umshini wokuqhumisa isihlabathi, ukuze kuhlangatshezwane kangcono nezidingo zokusetshenziswa, abasebenzisi abaningi abacaci mayelana nokusebenza okuqondile kanye nenjongo yokupompa umoya wendawo wemishini, ngakho-ke ukusebenza okuhambisanayo kwethulwa ngokulandelayo, ukuze ukuze uhlangabezane kangcono nezidingo zokusetshenziswa.
Umshini wokuqhumisa isihlabathi (igumbi) kumele ufakwe umoya wendawo. Abasebenzi basebenza ngaphandle kwemishini, i-sandblasting yenziwa ekamelweni elivaliwe. Ukunqunywa kwevolumu yokumpompa umoya kusekelwe esimisweni sokuthi uthuli lungakhishwa futhi ubuso bezingxenye bungabonakala ngokucacile lapho kwenziwa i-sandblasting. Ivolumu yokumpompa umoya ngokuvamile ingabalwa ngokuvumelana nesivinini somoya sendawo yesigaba sezinto zokusebenza ezingaphakathi endlini ku-0.3-0.7 m/s. Indawo yesigaba inqunywa ngokulandela isiqondiso sokugeleza komoya. Ukukhethwa kwesivinini somoya kwesigaba kufanele kucabangele izinga lokuvala lemishini, ubukhulu bombhobho, ubukhulu begumbi lokuqhuma kwesihlabathi nezinye izici. Ngokuvamile, isivinini somoya sesigaba esiphambanayo segumbi elikhulu lokuqhunyiswa kwesihlabathi sithatha inani elincane, futhi isivinini somoya sesigaba esiphambanayo segumbi elincane le-sandblasting lithatha inani elikhulu. Izinto ezisetshenziswayo) ngokuya ngevolumu yasendlini ukucatshangelwa kwevolumu yomoya okhishwayo elinganiselwa kuhlu.
Uthuli olukhishwe ezintweni zokusebenza ludinga ukususwa futhi luhlanzwe emkhathini. Kuyadingeka ukugwema ukungcoliswa kwemvelo kanye negesi yothuli engena kwezinye izindawo zokusebenzela ze-workshop ngenxa yokususwa kothuli ngendlela engafanele.
Okusalungiswa kwasendaweni komshini wokupholisha nokupholisha
Inani elikhulu lothuli lwensimbi nothuli olunemicu kukhiqizwa ekupholishweni nasekupholishweni kwezingxenye zensimbi, ezidinga ukuqedwa ngokungenisa umoya wendawo. Kudingeka ukususa uthuli ngaphambi kokuphumela emkhathini.
Ukupendwa kwesifutho sezingxenye ngokuvamile kwenziwa ekamelweni lesifutho, futhi idivayisi yendawo yokumpompa umoya enokuhlunga kwamanzi eshawa noma ukuhlunga okomile kufanele kumiswe ukuze inkungu kapende ingaphumi emgodini osebenzayo uye ekamelweni.
Ukususwa kokugqwala kanye nomsebenzi wokupenda wezingxenye ezincane kungenziwa ebhentshini lokusebenza noma ku-fume hood ngokukhipha umoya wendawo, futhi ivolumu yokukhipha umoya ingu-0 ngokuya ngesivinini somoya sesigaba se-orifice sokungena emoyeni. Ibalwa ngamamitha ngomzuzwana.
Umshini wokuqhumisa isihlabathi (igumbi) igroove kapende wokucwilisa kanye nethreyi likapende lokuwisa lidinga ukumpontshwa komoya wendawo, ukumpompa komoya kungasetshenziswa ukumunca eceleni noma uhlobo lwe-fume hood.
Okungenhla ukwethulwa komsebenzi wendawo wokumpompa umoya womshini wokuqhumisa isihlabathi. Ngokwesethulo salo, izindlela ezithile zokusebenza zingaqondwa ngokucacile, ukuze kugwenywe amaphutha futhi kuholele ekuveleni kwethonya lokusetshenziswa kwemishini.
