Isingeniso: Inhliziyo Ye-Weld
Ekukhiqizweni kwamapayipi ahlanganisiwe asebenza isikhathi eside (HF), inqubo yokushisela iyinhliziyo yomsebenzi wonke. Ikhwalithi, amandla, kanye nokubukeka komkhiqizo wokugcina konke kunqunywa kulesi sigaba esibucayi. Nakuba umgomo ufana—ukudala umthungo ophelele—indlela esetshenziswayo ukuwufeza yenza umehluko omkhulu.
Kunezindlela ezimbili zokukwenzaukushisela okuvama kakhulu: ukushisela kokuthintana kanye nokushisela kokungenisa.
Ukushisela Okuthintayo
Ukushisela kokuthintana kusebenzisa ama-electrode ethusi amabili athintana nezinhlangothi zombili zepayipi lensimbi elizoshiselwa. Ugesi obangelwayo ungena kahle. Imiphumela emibili yogesi ovame kakhulu yenziwa ngcono ngenxa yokuxhumana okuqondile phakathi kwama-electrode ethusi nepuleti lensimbi. Ngakho-ke, ukusebenza kahle kokushisela kokushisela kokuthintana kuphakeme futhi kusebenzisa amandla aphansi, kusetshenziswa kabanzi ekukhiqizweni kwamapayipi asheshayo nanokunemba okuphansi, futhi ukushisela kokuthintana ngokuvamile kuyadingeka lapho kukhiqizwa amapayipi ensimbi aqinile kakhulu. Kodwa-ke, kunezinkinga ezimbili ekushiseleni kokuthintana: eyodwa ukuthi i-electrode yethusi ithintana nepuleti lensimbi, futhi iyaguga ngokushesha; enye ukuthi ngenxa yethonya lokuba yisicaba kobuso bepuleti lensimbi kanye nokuqondile komphetho, ukuzinza kwamanje kokushisela kokuthintana kubi, kanti ama-burrs angaphakathi nangaphandle e-weld aphezulu kakhulu. , Ngokuvamile ayisetshenziswa lapho kushiselwa amapayipi anokunemba okuphezulu nanodonga oluncane.
Ukushisela kwe-Induction
Ukushisela kokungenisa kungukugoqa ukujika okukodwa noma ngaphezulu kwamakhoyili okungenisa ngaphandle kwepayipi lensimbi ukuze kushiselwe. Umphumela wokujika okuningi ungcono kunokujika okukodwa, kodwa kunzima kakhulu ukukhiqiza nokufaka amakhoyili okungenisa amaningi. Ukusebenza kahle kuphakeme uma ibanga phakathi kwekhoyili yokungenisa kanye nobuso bepayipi lensimbi lincane, kodwa kulula ukubangela ukukhishwa phakathi kwekhoyili yokungenisa kanye nepayipi. Ngokuvamile, kuyalulekwa ukugcina igebe elingu-5-8 mm phakathi kwekhoyili yokungenisa kanye nobuso bepayipi lensimbi. Uma usebenzisa ukushisela kokungenisa, njengoba ikhoyili yokungenisa ingathintani nepuleti lensimbi, akukho ukuguguleka, futhi ugesi wokungenisa uzinzile, okuqinisekisa ukuzinza kokushisela. Ikhwalithi yobuso bepayipi lensimbi ngesikhathi sokushisela ilungile, futhi umthungo wokushisela ubushelelezi. Kumapayipi anembile, kusetshenziswa ukushisela kokungenisa ngokuyisisekelo.
