Iyo wunvise 'idasanzwe ya alloy sleeve', ishusho ihita iba umuyoboro wo murwego rwohejuru gusa. Ngiyo imyumvire ya mbere itari yo. Mubimenyerezo, nibintu bikora bisobanurwa nibidukikije - ubushyuhe bukabije, itangazamakuru ryangirika, cyangwa abrasion idahwema. 'Umwihariko' ntabwo ari ibicuruzwa byo kwamamaza; ni itandukaniro hagati yigice kimara igihe kimwe nikirokoka kwiyamamaza. Nabonye imishinga myinshi ifata nkikintu cyibicuruzwa, gusa guhura nikibazo cyo kunanirwa imburagihe mugihe cya FAT. Ikibazo nyacyo ntabwo ari ugutoranya Ni-Cr cyangwa Co-shingiye kuri datasheet; ni ukumva uburyo inzira yo gukora, kuva gukina kugeza kurangiza, gufunga imikorere-cyangwa gutangiza inenge zihishe.
Kutumva neza: Ibikoresho nibigize
Impapuro nyinshi zerekana kwibanda ku bihimbano: Inconel 625, Hastelloy C-276, Icyogajuru 6. Ngiyo intangiriro, ntabwo ari umurongo wanyuma. Ndibuka umushinga kubakiriya ba peteroli aho twakomereje a idasanzwe Kugaragara nka Inconel 718. Yagenzuye ibisanduku byose bya shimi. Nyamara, yacitse munsi yumukino wo gusiganwa ku magare muri serivisi. Isesengura ryatsinzwe ntabwo ryerekanye urwego rwibintu, ahubwo ryerekanye imiterere yingano. Byari byarakorewe mububiko, kandi impeke zitari nziza kubera impungenge za axial na radial yabonye. Ibigize abakinnyi, nubwo bafite chimie imwe yizina, yaba ifite imiterere ya isotropique ikwiranye numutwaro. Iri ni isomo utibagiwe.
Aha niho uburambe bwumushinga buba ingirakamaro. Isosiyete nka Qingdao Qiangsenyuan Technology (QSY), hamwe nimyaka mirongo itatu muri shell no gushora imari, irabyumva neza. Ntabwo bagurisha ibyuma gusa; bagurisha uburyo. Kuri a idasanzwe bigenewe pompe yubushyuhe bwo hejuru, gahunda yo gushora imari batanga irashobora gutanga igice cyegeranye-net-igizwe nigice cyagenzuwe, cyiza cyimbuto zisanzwe zirwanya umunaniro wumuriro ugereranije nigice cyavuye mumabari mpimbano. Itandukaniro riri muri microstructure, ikintu umukozi ushinzwe amasoko asoma ibipimo ntashobora na rimwe gutekereza.
Guhitamo hagati yo gukina no gutunganya ibintu bikomeye ntabwo ari ikiguzi gusa. Byerekeranye na geometrie. Akenshi, akaboko gakenera imiyoboro y'imbere yo gukonjesha cyangwa flanges.
