Umshini wokusika igesi usezingeni eliphezulu, ukunemba okuphezulu nokwethenjelwa okuphezulu kwemishini yokusika elawulwa yikhompyutha, imishini yokunemba kanye nobuchwepheshe begesi.
Yiziphi izinzuzo zomshini wokusika igesi?
Indlela yokubhekana namaphutha avamile omshini wokusika iGesi?
Iyini isimiso sokusebenza somshini wokusika igesi?
Yiziphi izinzuzo zomshini wokusika igesi?
Umshini wokusika igesi unezinzuzo zesisindo esilula, amandla aphezulu, ukumelana nokugqwala, isakhiwo esihlangene, ukusebenza okulula nokusetshenziswa okuphephile. Umshini wokusika igesi usebenzisa i-acetylene ene-medium-pressure kanye ne-high-pressure oxygen emsebenzini wokusika. Ingakwazi ukusika amapuleti ensimbi ngogqinsi olungaphezu kuka-8 mm, ikakhulukazi ukusika umugqa oqondile, kanye nokusika okuyisiyingi ngobubanzi obungaphezu kuka-200 mm, kanye nokusika kwe-bevel ne-V. Ingasebenzisa futhi amandla omshini wokusika iGesi kanye namadivayisi engeziwe afanayo ukwenza ukucisha ilangabi kanye nokushisela ipulasitiki. Ubukhulu obuphezulu bepuleti lensimbi elisikiwe bungafinyelela ku-12.5. Ngokuvamile, akukho ukusikwa kwendawo okungenziwa ngemva kokusika.
Indlela yokubhekana namaphutha avamile omshini wokusika iGesi?
1. Ukulimala kwephuzu lokusika kanye ne-electrode: Uma ithiphu yokusika yomshini wokusika iGesi ifakwe ngendlela engafanele, ingaqiniswa, noma ithoshi lokusika elipholile ngamanzi alixhunyiwe ohlelweni lokupholisa, ukulahlekelwa kwephuzu lokusika kuzokwanda.
Isixazululo: Lungisa igiya elifanele lemishini ngokuya ngemingcele efanele ye-workpiece yokusika, futhi uhlole ukuthi ithoshi lokusika kanye nobhobho wokusika kufakwe ngokuqinile yini; ithoshi lokusika elipholile ngamanzi kufanele lijikeleze amanzi okupholisa kusengaphambili.
2. Ukucindezela komoya okokufaka kuphezulu kakhulu: uma ukucindezela komoya okokufaka komshini wokusika iGesi kungaphezu kuka-0.45MPa, ukugeleza komoya okunengcindezi enkulu ngemva kokwakhiwa kwe-arc ye-plasma kuzokhipha ikholomu ye-arc egxilile, kuhlakaze amandla ikholomu ye-arc futhi yenza buthaka amandla okusika we-arc ye-plasma.
Isixazululo: Hlola ukuthi ukulungiswa kwengcindezi ye-compressor yomoya kulungiswe kahle yini, bese unquma ukuthi ukucindezela kwe-compressor yomoya kuyahambisana yini nokucindezela kwesihlungi somoya sokunciphisa i-valve. Lungisa ukushintshwa kokulungiswa kwesihlungi somoya sokunciphisa i-valve ngesikhathi sokusebenza kwe-compressor yomoya. Uma igeji yomfutho womoya ingashintshi, kusho ukuthi ivalvu yokunciphisa umfutho womoya ayisebenzi futhi kufanele ishintshwe ngesikhathi.
Iyini isimiso sokusebenza somshini wokusika igesi?
Ukusika okushisayo kwento yokuhlukanisa ilangabi okukhiqizwa ukushiswa okuxubile kwegesi evuthayo nomoya-mpilo, okwaziwa nangokuthi ukusika umoya-mpilo noma ukusika amalangabi. Ngesikhathi sokusika igesi, ilangabi lishisa kuqala okubalulekile endaweni yokuthungela endaweni yokusika, bese lijova umfudlana komoyampilo ukuze lenze into yensimbi i-oxidize futhi ishe, futhi i-oxide slag ekhiqiziwe ivunguzwa ukugeleza komoya ukuze yakhe ukusika. Ukuhlanzeka kwe-oxygen esetshenziswa emshinini wokusika iGesi kufanele kube kukhulu kune-99%; igesi evuthayo ngokuvamile isebenzisa igesi ye-acetylene, kodwa futhi ingasebenzisa igesi ye-petroleum, igesi yemvelo noma igesi yamalahle. Ukusebenza kahle kokusika ngegesi ye-acetylene kuphezulu kakhulu, ikhwalithi ingcono, kodwa izindleko ziphakeme.
