Enkambisweni yokusebenzisa umshini wokuqhumisa isihlabathi, ukuze kuhlangatshezwane kangcono nezidingo zokusetshenziswa, abasebenzisi abaningi abacaci ngokusebenza kanye nenhloso yokupompa umoya wendawo kwemishini, ngakho-ke ukusebenza okuhambisanayo kuqaliswa ngokulandelayo, ukuze kuhlangatshezwane kangcono nezidingo zokusetshenziswa.
Umshini wokuqhumisa isihlabathi (igumbi) kumele ube nomoya wokungenisa umoya wendawo. Abasebenzi basebenza ngaphandle kwemishini, ukuqhumisa isihlabathi kwenziwa ekamelweni elivaliwe. Ukunqunywa komthamo wokufutha umoya kusekelwe esimisweni sokuthi uthuli lungasuswa futhi ubuso bezingxenye bubonakale kahle lapho kuqhunyiswa isihlabathi. Umthamo wokufutha umoya ngokuvamile ungabalwa ngokwejubane lomoya lendawo yengxenye yemishini ngaphakathi ku-0.3-0.7 m/s. Indawo yengxenye inqunywa ngokwesiqondiso sokugeleza komoya. Ukukhethwa kwesivinini somoya sengxenye kufanele kucabangele izinga lokuvala imishini, usayizi we-nozzle, usayizi wegumbi lokuqhumisa isihlabathi nezinye izici. Ngokuvamile, isivinini somoya sengxenye yengxenye yegumbi elikhulu lokuqhumisa isihlabathi sithatha inani elincane, kanti isivinini somoya sengxenye yengxenye yegumbi elincane lokuqhumisa isihlabathi sithatha inani elikhulu. Imishini) ngokwevolumu yangaphakathi, ukucatshangelwa komthamo womoya wokukhipha olinganiselwayo kubhalwe ohlwini.
Uthuli olukhishwe emishinini ludinga ukususwa futhi luhlanzwe emoyeni. Kubalulekile ukugwema ukungcoliswa kwemvelo kanye negesi yothuli ukungena kwezinye izindawo zokusebenzela ze-workshop ngenxa yokususwa kothuli ngendlela engafanele.
Umshini wokupholisha nowokupholisha wendawo
Kukhiqizwa uthuli olukhulu lwensimbi kanye nothuli olunemicu ekupholisheni nasekupholisheni izingxenye zensimbi, okudingeka zisuswe ngokungenisa umoya endaweni. Kudingeka ukususwa kothuli ngaphambi kokukhipha umoya emoyeni.
Ukupenda izingxenye ngokufutha ngokuvamile kwenziwa egumbini lokufutha, futhi kufanele kufakwe idivayisi yokupompa umoya yendawo enokuhlunga amanzi eshaweni noma ukuhlunga okomile ukuze inkungu yopende ingaphumi emgodini osebenzayo iye egumbini.
Ukususwa kokugqwala kanye nomsebenzi wokupenda izingxenye ezincane kungenziwa ebhentshini lokusebenzela noma ebhodweni lomusi ngokukhishwa komoya wendawo, futhi ivolumu yokukhishwa komoya ingu-0 ngokuya ngesivinini somoya sesigaba sokusebenza kwe-air inlet orifice. Kubalwa ngamamitha ngomzuzwana.
Umshini wokuqhumisa isihlabathi (igumbi) umsele wokupenda wokucwilisa kanye nethreyi yokupenda ephonsayo kudinga ukupompa umoya wendawo, ukupompa umoya kungasetshenziswa uhlobo lokufutha ohlangothini noma uhlobo lwe-fume hood.
Lokhu okungenhla ukwethulwa kokusebenza kokupompa umoya kwendawo komshini wokuqhumisa isihlabathi. Ngokwesethulo sawo, izindlela ezithile zokusebenza zingaqondakala ngokucacile, ukuze kugwenywe amaphutha futhi kuholele ekuveleni kwethonya lokusetshenziswa kwemishini.
