Ngokuthuthuka okuqhubekayo kwesayensi yesimanje, ubuchwepheshe, kanye nezimboni, indawo yokusebenza yezingxenye nezingxenye iya ngokuya iba yinkimbinkimbi, futhi izidingo zezakhiwo ezingaphezulu ziya ngokuya ngokuya phezulu. Ngakho-ke, izinga le-scrap yezingxenye liye landa kakhulu. Izingxenye ezivame ukuchithwa ngenxa yokwehluleka kwendawo zihlanganisa ama-rotor blades, izingxenye ze-shaft, izingxenye zegiya, isikhunta, njll.
Izingxenye ezinomonakalo ongaphezulu kuphela zingalungiswa ngaphansi kwesimo sokuthi ukusebenza okuphelele kwezingxenye kuhlangabezana nezimo zokusebenza. Uma izingxenye ezilahliwe ngenxa yokungacutshungulwa kahle noma ukulimala kwesevisi kungalungiswa, ngeke nje kuphela kubuyiswe ukulahlekelwa okukhulu kwezomnotho nesikhathi, kodwa futhi nokusetshenziswa kwezinsiza kungathuthukiswa, okuhambisana nesu lentuthuko esimeme yomhlaba.
Indlela yokulungisa izingxenye ingaba ukulungiswa kwe-laser cladding. Isekelwe ezimeni zokusebenza ze-workpiece, i-laser cladding metal enezici ezihlukahlukene zokuklama ukuze kulungiswe ungqimba olunamanzi okumelana nokushisa, ukumelana nokugqwala, ukumelana ne-oxidation, ukumelana nokukhathala, noma ukukhanya. kanye nezakhiwo kazibuthe. Ukulungiswa kwe-laser cladding kuyinqubo yokupholisa ngokushesha. Ngesikhathi senqubo yokugqoka, okokufaka ukushisa ku-workpiece elungisiwe kuncane, indawo ethintekile ukushisa incane, isendlalelo se-cladding sinesakhiwo esihle, futhi kulula ukusebenzisa i-automation. Ngakho-ke, i-laser cladding isetshenziselwa ukulungisa. Izingxenye ezinjengama-rotors zinikeza izinzuzo ezinkulu kunezinye izindlela. Ubuchwepheshe be-Laser cladding buxazulula uchungechunge lwezinkinga zobuchwepheshe ezifana nokushisa okushisayo kanye nokulimala kokukhathala okushisayo okungenakugwemeka ngesikhathi sokucubungula okushisayo okufana nokushisela ugesi wendabuko kanye ne-argon arc welding. Iphinde ixazulule amandla okubopha phakathi kokunameka kanye ne-substrate ngesikhathi sokucubungula okubandayo okufana ne-electroplating yendabuko kanye nokufutha. Ukuphikisana okungalungile, okunikeza indlela enhle yokulungiswa kwendawo.
Ama-rotor blades, abizwa nangokuthi ama-movering blades, angama-blades ajikeleza ngesivinini esikhulu nge-rotor. Ukujikeleza kwejubane eliphezulu kwama-blades kuqonda ukuguqulwa kwamandla phakathi kokugeleza komoya kanye ne-rotor. Ama-rotor blades athwala amandla amakhulu amakhulu e-inertial, amandla amakhulu e-aerodynamic, nemithwalo yokudlidliza, futhi amelana nokugqwala kanye ne-oxidation yemithombo yezemvelo, kanye nokuguguleka kwezinhlayiya ezincane ezihamba ngesivinini esikhulu. Kodwa-ke, ukucubungula kunzima, futhi ama-turbine rotor blades kufanele acutshungulwe emazingeni okushisa aphezulu. Sebenza esimweni. I-rotor blade iyingxenye ebalulekile ethinta ngokuqondile ukusebenza, ukwethembeka, nokuphila kwenjini. Izimo zayo zokusebenza zinzima kakhulu futhi kulula ukonakala. Ngakho-ke, izidingo zokusebenza kwempahla nazo zithuthukiswe kakhulu. Ngesikhathi esifanayo, izindleko zezomnotho zezinto ezibonakalayo ziye zanda, futhi amakhasethi okulungisa nawo asetshenziselwe wona. Woza emakethe enkulukazi. Ukusetshenziswa kobuchwepheshe be-laser cladding kuma-rotor blades kufundwe kahle, okubuye kunikeze imfuneko evumayo yokusetshenziswa kwayo ekulungiseni.
Ukulungiswa kwezingxenye ze-shaft
Imvamisa, izimbangela eziyinhloko zokwehluleka kwezingxenye ze-shaft zifaka ukuguqulwa kwe-shaft, ukuphuka kwe-shaft, kanye nokwehluleka kwe-shaft surface. Ucwaningo luveza ukuthi ukulimala kwezingxenye ze-shaft ezifana nama-generator shafts kanye ne-transmission shaft ehlukahlukene kubangelwa ikakhulukazi ukuguga. Phakathi kwazo, ukuguqulwa kwe-shaft kanye nokuphuka kwe-shaft akukwazi ukulungiswa, kodwa ukwehluleka kwendawo ikakhulukazi okubangelwa ukugqoka kungalungiswa. Usebenzisa ubuchwepheshe bokukhanda i-laser cladding enamandla amakhulu, ungqimba lwensimbi esekwe ku-alloy lungaba ukumbozwa kwe-laser endaweni ehlulekile yezingxenye ze-shaft, ukuze ingaphezulu lezingxenye ezine-cladding alloy layer ibe nezakhiwo ezinhle zemishini, kanye nezingxenye ezilahliwe. ingasetshenziswa kabusha.
Isikhunta sidlala indima ebalulekile ekubumbeni ukubunjwa kanye nokucubungula ukubumba kwepulasitiki. Inqubo yayo yokukhiqiza iyinkimbinkimbi, umjikelezo wokukhiqiza mude, futhi izindleko zokucubungula ziphezulu. Ngakho-ke, ukulungisa nokusebenzisa kabusha isikhunta esihlulekile ngokungangabazeki kunezinzuzo ezinkulu zezomnotho. Impilo yesevisi yesikhunta incike ekutheni ikwazi ukumelana nokugqoka kanye nokulimala kwemishini. Uma sekwenzekile ukuguga ngokweqile noma ukulimala komshini, kufanele kulungiswe ngaphambi kokuthi kusetshenziswe futhi. I-Laser cladding isiphenduke indawo yocwaningo yokulungisa isikhunta futhi idonse ukunaka okukhulu kosolwazi basekhaya nabangaphandle.
Indlela ye-laser cladding yokulungisa ukugqokwa kwesikhunta ingafingqwa ngale ndlela elandelayo: ukusebenzisa i-laser enamandla amakhulu enamandla aqinile P kanye nokugeleza kwempushana eshisayo ukuze kube isigameko endaweni yokubumba ngesikhathi esifanayo, ingxenye ukukhanya kwesigameko kuyavezwa, ingxenye yokukhanya iyamuncwa futhi ngokushesha Ngemva kokuba amandla amuncwa edlula inani elibalulekile, insimbi iyancibilika ukuze yenze ichibi elincibilikisiwe, elibe seliqina ngokushesha ukuze lenze ukuvala okuboshwe ngensimbi. I-laser beam iskena emuva naphambili ukuze ilungise umugqa wokubumba ngomugqa kanye nongqimba ngongqimba ngokuya ngomzila onikezwe uhlelo lokusebenza lokuthuthukisa lwesibili lwe-CAD. Ikakhulukazi, isikhunta esilungisiwe sidinga cishe akukho ukucutshungulwa kabusha.
