Izinzuzo zokucubungula izintambo zokudonsa nge-laser
Izinduku zokubopha amafutha ziyithuluzi elibalulekile nelibalulekile enkambisweni yokukhipha uwoyela. Zisebenza ezindaweni ezinzima isikhathi eside futhi zisengozini yokulimala okuhlukahlukene njengokuguguleka nokugqwala, okunciphisa isikhathi sazo sokusebenza futhi kwandise imvamisa yokushintshwa, okuletha ingcindezi enkulu yezindleko ekukhiqizweni kwensimu kawoyela. Kodwa-ke, ngokuthuthukiswa nokusetshenziswa kobuchwepheshe be-laser cladding, ukulungiswa nokusetshenziswa kabusha kwezinduku zokubopha amafutha sekuyinto engenzeka, okungagcini nje ngokunciphisa kakhulu izindleko zokukhiqizwa kukawoyela, kodwa futhi kuthuthukisa izinzuzo zezomnotho zensimu kawoyela.
1. Isimiso sobuchwepheshe bokulungisa ukulungiswa kwe-laser cladding yezinduku zokudonsa
Ukulungiswa kokulungiswa kwe-laser cladding yezinduku zokudonsa kuyigatsha elibalulekile emkhakheni wobuchwepheshe bokuguqulwa kobuso bezinto ezibonakalayo. Ngokwencazelo, isebenzisa i-laser beam enamandla aphezulu njengomthombo wokushisa ukuze ilethe ngokunembile i-alloy powder ethile engxenyeni eyonakele yenduku yokudonsa. Ngaphansi kwamandla aphezulu e-laser beam, i-alloy powder iyancibilika ngokushesha futhi incibilike kanyekanye nengqimba encane yezinto ebusweni be-sucker rod matrix. Ngemva kokupholisa ngokushesha, kwakheka ungqimba lwe-cladding oluhlanganiswe ngensimbi ne-matrix ebusweni benduku yokudonsa.
2. Uma kuqhathaniswa nezindlela zokulungisa zendabuko, ukucutshungulwa kokulungiswa kwe-laser cladding kwezinduku zephampu kunezinzuzo ezibalulekile, ezibonakala kakhulu kulezi zici ezilandelayo:
1) Amandla aphezulu okubopha ngensimbi: Ukumbozwa nge-laser kusebenzisa umsebe we-laser onamandla aphezulu ukuncibilikisa kancane ubuso bento yokusebenza, futhi ngesikhathi esifanayo kuncibilikisa ngokuphelele i-alloy powder ukuze kwakheke ungqimba oluqinile oluboshwe ngensimbi ku-substrate. Le ndlela yokubopha ayigcini nje ngokuba namandla aphezulu, kodwa futhi inesakhiwo sokubopha esiqinile esingenazo iziphambeko ezifana nokuqhekeka.
2) Ukumelana nokuguguleka kanye nokumelana nokugqwala: Ukumbozwa nge-laser kungakha ungqimba lwe-alloy olunokumelana okuhle kakhulu nokugqwala kanye nokumelana nokugqwala ebusweni bezinto zokusebenza zensimbi yekhabhoni ezivamile, ngaleyo ndlela kuthuthukise kakhulu ukumelana nokugqwala kanye nokumelana nokugqwala kwenduku yepompo futhi kwandise impilo yayo yenkonzo.
3) Nciphisa izindleko kanye nokusetshenziswa kwamandla: Ubuchwepheshe bokumboza nge-laser bungalungisa izindawo ze-alloy ezisebenza kahle kakhulu kuma-substrate ashibhile, konge izindleko zezinto ezibonakalayo. Ngesikhathi esifanayo, ngenxa yokufakwa okuncane kokushisa kanye nokuguqulwa kwenqubo yokumboza nge-laser, ivolumu yokucubungula elandelayo incane, okunciphisa kakhulu ukusetshenziswa kwamandla kanye nezindleko zokucubungula.
4) Ikhwalithi ephezulu yokumboza: Ukumboza okutholwe ngokumboza nge-laser kunezinga eliphansi lokumboza (ngokuvamile elingaphansi kuka-5%) futhi kuhlanganiswe ngokuqinile ngensimbi noma kusakazwe nge-substrate. Ngaphezu kwalokho, ukwakheka kokumboza kanye nokumboza kuyalawuleka, okuqinisekisa ikhwalithi ephezulu yokumboza. 5. Ukuguquguquka okuhle: Ubuchwepheshe bokumboza nge-laser bungafeza ukulungiswa okunembile kokumboza kwezindawo zokusebenza eziyinkimbinkimbi, futhi bufanele ukulungisa izinduku zepompo zezinto ezahlukene kanye nezimo.
