Iyo abajenjeri bagaragaje ibice byuma byuma bya sisitemu ya hydraulic, indangagaciro za peteroli, cyangwa inteko ziremereye cyane, ntibahitamo gusa ibikoresho-bahitamo gushikama kurwego rwo munsi yumuvuduko wumurongo wa 300+, kurwanya umunaniro nyuma yumuzingi wa 10⁶, hamwe no kwihanganira zeru kugabanuka kwa mikoro hejuru yikimenyetso gikomeye. Niyo mpamvu kuyobora OEM muri Amerika ya Ruguru hamwe n’Uburayi bidatanga inkomoko y’ibyuma bikoreshwa mu ruganda na catalog-bagenzura igenzura rya casting, bagenzura niba nodularity idahwitse hejuru yubushyuhe, kandi bakemeza imyirondoro iterwa no guterwa no gusigara mbere yo gusinya POs.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora kimwe muri ibyo bikoresho-byemewe na ISO, umucanga-n-ishoramari-rishobora guterana, hamwe na selile ya CNC yahinduwe kugeza ± 2 µm gusubiramo kubintu biri munsi yuburebure bwa mm 0.5. Twatunganije amazu arenga 17,000 yimyubakire yicyuma kubakora pompe ya piston kuva muri 2019. Muri buri cyiciro, dupima kubara nodular (ASTM A247), imbaraga zingana (byibuze 415 MPa), no kuramba (≥10%) - ntabwo ari rimwe gusa kuri tombora, ariko kumwanya wa axial kuri buri casting. Kubera iki? Kuberako akarere kamwe kari munsi ya nodular muri silinderi yimyubakire irashobora gutangiza umunaniro ukabije kuri 180 rpm ikomeza gukora. Twabonye ko bibaho. Kandi twahinduye uburyo bwo kwinjiza amarembo kugirango tuyakureho.
Kwishyira hamwe guhagaritse gutandukanya abatanga ibyiringiro nabacuruzi bacuruza. Kuri QINGDAO QIANGSENYUAN, ibyuma byangiza ntibigera bava mubigo kugeza ubugenzuzi bwa nyuma. Ibikoresho bito bigera mbere byemejwe: FCD450 cyangwa FCD600 yicyuma cyo mucyiciro, gishobora gukurikiranwa numubare wubushyuhe bwitanura hamwe nisesengura rya ladle. Gutera bibaho mu kirere kigenzurwa n’ikirere; intoki zokejwe neza neza neza (≤0.8%); igihe cyo kunyeganyega cyandikwa kuri buri cyiciro. Noneho haza gutunganywa - ntabwo ari intambwe itandukanye, ariko nk'ubugenzuzi bwagutse bwogukoresha inzira. Dufite umuhamagaro wa GD&T wibanda ku kwibanda (± 0,015 mm) no kurangiza hejuru (Ra ≤1,6 µm) ku maso hafunze kubera ko kudahuza hagati yintebe ya valve numubiri wibyuma byangirika bifitanye isano nigipimo cyo kumeneka mugupimisha API 598. Abakiriya batwoherereza ibishushanyo hamwe no kwihanganira imyanya ikarishye kuruta uko baterana - kandi turahura nabo, buri gihe.
Bamwe bashobora kuvuga ko guta hanze bitwara ibyago bitemewe. Ariko kwizerwa ntabwo bisobanurwa na geografiya-byerekanwe muburyo bwa metallurgical. Iyo pompe yuburayi OEM yahindukiye muruganda rwacu rukora ibyuma byububiko bwa AMS 5387 cobalt-alloy pump rotors * na * bihuza amazu yicyuma, byasabye ko coefficient zo kwagura amashyanyarazi zikoreshwa mubikoresho byombi. Twafatanije gukora protocole yihariye yo gukingira hamwe nuwaduhaye ibikoresho fatizo-twongeyeho ferrosilicon idasanzwe-yahinduwe na ferrosilicon ku bushyuhe bwuzuye bwashushe - kugirango duhindure imiterere ya grafite nodule morphologie tutabangamiye imbaraga zingana. Igisubizo? Guhuza coefficient muri 0.3 × 10⁻⁶ / ° C kurwego rwa 20–200 ° C. Nta rework. Nta murima watsinzwe. Imikorere isubirwamo gusa.
Dutanga ibyuma bisobanutse neza byuma aho kunanirwa atari amahitamo: umuvuduko wumuvuduko wamagare inshuro 12 kumunota kumyaka 15, imashini ya winch center shaft yunganira imitwaro ya toni 8 yingufu zangiza ibidukikije, umunyu wa pompe uhuza moteri ya kilowati 300 kurubuga rwa interineti. Igice cyose gitwara ibintu byuzuye - umubare wubushyuhe, isesengura ryimiti, ibisubizo byikizamini, raporo ya CMM. Ibicuruzwa byose birimo kwemeza ibipimo birwanya abakiriya-ingingo-yambere isabwa-ntabwo kwihanganira ISO rusange. Niba gusaba kwawe kugusaba uruganda rukora ibyuma rukora uruganda ubushobozi bufata ASTM A536 Icyiciro cya 65-45-12 nkintangiriro - ntabwo ari igisenge - ukeneye kugenzura neza nodularity, ubumenyi bwimikorere ya casting-mashini, hamwe na zeru-zeru QA ibyangombwa. Urwo ntabwo arirwo rurimi rwo kwamamaza. Ni urupapuro rwihariye duha abakiriya mbere yo gusubiramo.
