Umshini wokusika i-Junda Water jet ukusika ijethi yamanzi, okuvame ukubizwa ngokuthi ummese wamanzi.Ngokuthuthuka kwesayensi nobuchwepheshe, le ndlela yokusika ebandayo izosetshenziswa emikhakheni eminingi.Nasi isingeniso esifushane sokuthi kuyini ukusika amanzi.
Isimiso sokusika ijethi yamanzi
Ukusika ijethi yamanzi kuwubuchwepheshe obusha bomshini obandayo.Ingasetshenziswa ezimweni ezimbi, iziqhumane ezingavunyelwe, ezithinteka kakhulu.Ukusika indiza yamanzi kuyinhlanganisela yemishini, izinto zikagesi namakhompyutha.Izimpumelelo zobuchwepheshe obuphezulu bobuchwephesha bokulawula okuzenzakalelayo buyindlela entsha yokucubungula impahla eyakhiwe eminyakeni yamuva.
Umgomo wokusika ijethi yamanzi ukusebenzisa amanzi athile ahlanzekile anomfutho ophezulu noma i-slurry ene-abrasive cutting, ngokusebenzisa ikholomu yoketshezi lomjovo we-nozzle enamandla amakhulu womthelela, umthelela oqondile ozocutshungulwa ukuze usike.Ngokusho kwengcindezi yamanzi ehlukene, ingahlukaniswa ibe yi-low pressure water jet cutting kanye ne-high pressure water jet cutting.
izici zokusika i-jet yamanzi
Ubuchwepheshe bokusika indiza yamanzi bunezici ezilandelayo:
(1) Ukusika umfutho wejethi wamanzi mkhulu.Umfutho wendiza yamanzi ungamashumi kuya kumakhulu ama-megapascal, okuyijubane eliphindwe izikhathi ezimbili kuya kwezingu-3 kunejubane lomsindo, okudala ukuminyana okukhulu kwamandla endiza ukusika izinto.Izinga lokushisa lokusika le-workpiece liphansi kakhulu, izinga lokushisa elijwayelekile alidluli i-100℃, okuyinzuzo evelele kakhulu uma kuqhathaniswa nezinye izinqubo zokusika ezishisayo.Lokhu kuqeda ithuba lokuguqulwa kwengxenye yokusika, indawo ethinteke ukushisa yengxenye yokusika, kanye nokwenzeka kokuguqulwa kwezicubu.Ingasetshenziswa ngokuphepha nangokuthembekile ezindaweni lapho iziqhumane zivinjelwe khona ngokuqinile, njengezinkundla zokumba uwoyela ogwini, izindawo zokuhluza uwoyela, amathangi amakhulu kawoyela kanye namapayipi kawoyela negesi.
(2) izinga lokusika le-jet jet cutting lihle kakhulu, indawo yokusika ibushelelezi, ayikho i-burr ne-oxidation residue, igebe lokusika lincane kakhulu, ngokusika kwamanzi ahlanzekile, ngokuvamile lingalawulwa ngaphakathi kwe-0.1 mm;Engeza i-abrasive yokusika ethile phakathi kuka-1.2-2.0mm, ukusika akudingi ukucutshungulwa kwesibili, yenza inqubo yokucubungula ibe lula.
(3) Ububanzi besikrini sokusika bubanzi ngokuqhathaniswa.Ubukhulu bokusika ummese wamanzi bubanzi, ubukhulu bokusika bungaba bukhulu kuno-100mm.Kumapuleti ensimbi akhethekile anogqinsi lwe-2.0mm, isivinini sokusika singafinyelela ku-100cm/min.Nakuba isivinini sokusika i-jet yamanzi singaphansi kancane kokusikwa kwe-laser, kodwa inqubo yokusika ayikhiqizi ukushisa okukhulu kokusika, ngakho-ke ekusebenziseni okusebenzayo, ukusika i-jet yamanzi kunezinzuzo eziningi.
(4) Uhlu olubanzi lwezinto zokusika.Le ndlela yokusika ayifanele kuphela ukusika insimbi nokungeyona insimbi, kodwa futhi nokucubungula izinto ezihlanganisiwe nezinto ezishisayo.
(5) Indawo yokusebenza enhle kakhulu yenqubo yokusika indiza yamanzi ayinayo imisebe, akukho zinhlayiya ezifafazayo, ukugwema ukwenzeka kokundiza kothuli, ungangcolisi imvelo.Ukusikwa kwejethi yamanzi okugaya okulinganayo, uthuli olubi kanye nama-chips kungabuye kugezwe ngokuqondile ukugeleza kwamanzi, ku-collector, ukuqinisekisa impilo yomqhubi, kungabizwa ngokuthi ukucubungula okuluhlaza.Ngenxa yezinzuzo zokusika indiza yamanzi, inamathemba abanzi okusebenza ku-aerospace, amandla e-athomu, i-petroleum, imboni yamakhemikhali, ubunjiniyela bangaphansi kwamanzi kanye nezimboni zokwakha.
