Urumva 'Satelite sleeve' kandi injeniyeri benshi bahita batekereza 'bigoye, birinda kwambara, byiza kubushyuhe bwo hejuru'. Nibyo, ariko kandi niho birenze urugero. Mumyaka yanjye gushakisha no kwerekana ibi bice, cyane cyane kuri pompe ya pompe na valve bituruka muri serivisi zikomeye, Nabonye itandukaniro riri hagati yisobanura rya kataloge nukuri kubutaka. Ntabwo ari ibicuruzwa gusa; imikorere yacyo ibaho cyangwa ipfa kubwo guhitamo icyiciro cya alloy, ubunyangamugayo bwa casting, kandi cyane cyane, nyuma yimashini. Imashini idahwitse ya Stellite 6 irashobora kunanirwa byihuse kuruta ibyuma bya karubone bivuwe neza mubidukikije bimwe na bimwe. Ibi ntabwo ari theoretical-nibyo wiga nyuma yo gukemura ibibazo bike byananiranye hakiri kare hanyuma ugacukumbura 'impamvu'.
Amavuta ntabwo arinkuru yose
Icyogajuru, umuryango wa cobalt-chromium alloy wo muri Kennametal, uza mumanota. Icyogajuru 6, 12, 21 - buri kimwe gifite icyicaro cyacyo. 6 numurwanyi rusange-intego, ikomeye yo kwambara hamwe no kwangirika. Ariko hano hari umutego uhuriweho: kwerekana Stellite 6 kubintu byose kuko izwi cyane. Ndibuka umushinga wa pompe yimiti ikora pompe ikora ubushyuhe, abrasive slurry. Icyambere cyambere cyari Stellite 6 amaboko. Bamaranye hafi 40% yubuzima buteganijwe. Isesengura ryatsinzwe ryerekanaga imbaraga zidahagije zo guhangana na progaramu yihariye yubushyuhe. Guhindukira kuri Stellite 12, ifite imiterere ya karbide itandukanye, yasubije ubuzima kumurongo. Isomo? Ikiboko nticyoroshye gusa; ni a Icyogajuru 12 cyangwa Icyogajuru 21 amaboko. Urwego rutegeka microstructure, kandi rutegeka ubuzima.
Aha niho gufatanya nurufatiro rwumva metallurgie, atari kubumba gusa, ni urufunguzo. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) biza mu mutwe. Hamwe nimyaka 30 yimyaka mumashusho no gushora imari idasanzwe, babona ibi. Ntushobora gusuka gusa aya mavuta nkicyuma. Igipimo cyo gukomera, ibikoresho bibumbabumbwe - byose bigira ingaruka ku ikwirakwizwa rya karbide.
