Iyo abajenjeri bagaragaje ASTM A747 bakina, ntabwo bahitamo gusa ibikoresho-biyemeza kugera kubikorwa. Ibipimo ngenderwaho bigenga amavuta ya cobalt-chromium-nikel yagenewe kwambara bikabije, kwangirika, no kurwanya ubushyuhe-cyane cyane mubice bya pompe bizunguruka, imibiri yumuvuduko mwinshi, hamwe na sisitemu ya hydraulic aho gutsindwa atari amahitamo. Ariko gushakisha ASTM A747 gukina ntabwo ari ugushaka * ibishingwe byose. Nibijyanye no gufatanya nuwabitanze ufata metallurgjique idahwitse nkibidashoboka, yemeza ubushyuhe bwose kurwanya imiti ya AMS 5387, kandi akagenzura urunigi rwuzuye: kuva T800 yo mu rwego rwa T800 ikurikirana kugeza kuri GD&T igenzurwa rya nyuma kuri CMM.
Kuki abashakashatsi ba "ASTM A747" bakunze gukubita
Twasuzumye RFQs zirenga 200 ziva muri pompe yo muri Amerika ya ruguru OEMs hamwe n’abatanga serivisi z’ibikomoka kuri peteroli mu mezi 18 ashize. Benshi batangirana n'ikibazo kimwe cyihutirwa: “Urashobora gutera ASTM A747 - ukabigaragaza?” Abatanga ibicuruzwa byinshi basubiza "yego" hanyuma bagahagarara kubyemezo bifatika. Bagirana amasezerano yo gushonga, basiba ibizamini bya ruswa hagati ya ASTM A262 Imyitozo E, cyangwa ntibashobora gutanga raporo yihariye yerekana amashusho. Twabonye gutoranya ibyiciro byanze-atari kubwikosa-ariko, kubera ko chromium yagabanutseho 0.3% munsi ya 28-32% isabwa na ASTM A747. Icyo cyuho ntigaragara ku gishushanyo. Yerekana nkibishishwa imburagihe muri serivisi ya gaz isharira.
Icyuho nyacyo ntabwo ari ubushobozi bwo gutora. Ni vertical vertical. Nukuri ASTM A747 yubahiriza isaba kugenzura ibyiciro bine bifitanye isano: gufata ibyemezo fatizo byemewe, gufata vacuum-arc byahinduwe (VAR) cyangwa gusuka gushiramo, gushiramo igisubizo hamwe nigihe cyo gushira neza / ibiti by'ubushyuhe, hamwe no kugenzura microstructure nyuma yubushyuhe. Hatabayeho kugenzura, "uruganda rwa ASTM A747" ruhinduka ururimi rwo kwamamaza - ntabwo ari ukuri kubyara umusaruro.
Aho gutora neza bihuye no kwemeza imikorere
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ASTM A747 ntabwo ari urutonde. Ni umusingi wibikorwa bya pompe yacu. Imirongo yacu yo guta umucanga isuka ubushyuhe munsi ya argon. Buri cyiciro gikora isesengura ryerekana mbere yo gusuka - na nyuma yo kuvura ubushyuhe. Tugumana ibisobanuro byuzuye: gushonga umubare, ubushyuhe bwubushyuhe bwo kugabanuka, igipimo cyo gukonjesha, hamwe nubukonje bwa Rockwell C muri zone eshatu za buri casting. Kubice bya AMS 5387 byujuje ubuziranenge - nka cobalt alloy nozzles yo gusubizaho pompe - twongeyeho ASTM E112 ingano yubunini hamwe na ASTM A262 Imyitozo E igerageza rya ruswa hagati y’abatangabuhamya.
Iyi disipuline ifite akamaro kanini kubice bya geometrie. Fata inzu ya pisitori ya piston: uburebure bwurukuta hejuru ya mm 0,15 mm itera kwaguka kwubushyuhe butaringaniye, biganisha ku gufatwa munsi yumutwaro. Inzira yacu ikomatanya ishoramari-ryukuri hamwe na CNC yakozwe na bokisi yibanze-hanyuma ikagenzura imyanda ikomeye hamwe no guhumeka ikirere hamwe no kurangiza hejuru hamwe na profilometrie. Igisubizo? Inzu ya silinderi ifashe <0.005 mm kuzenguruka kuri 300 mm z'uburebure, ndetse no muri T800 ishingiye kuri ASTM A747.
Bane badashobora kuganira kubutumwa bukomeye ASTM A747 itanga
- Ibikoresho bifatika.
- Gushyushya inyandiko: Buri ziko ryizengurutswe ryanditswemo - shyira igihe, igipimo cyikigereranyo, ikime cyikirere, hamwe no kuzimya ubushyuhe buciriritse - hamwe nimikono ya digitale ishobora gukurikiranwa no guhinduranya
- Muri metero: Ibipimo byingenzi byapimwe hagati ukoresheje Zeiss CONTURA G2 CMMs; ubusugire bwubutaka bwemejwe binyuze muri SEM yerekana amashusho yo gukata
- Guhuza ibizamini bikora.
Ibi ntabwo ari theoretical. Igihembwe gishize, twatanze 42 ASTM A747 ya shitingi ya sisitemu ya sisitemu yo hanze. Buri gice cyatwaraga ubushyuhe bwuzuye, imbaraga zingana> 1000 MPa, hamwe ningaruka zikomeye> 35 J kuri –20 ° C - byose byagenzuwe kuri ASTM E23. Umukiriya yavuze ko zeru zananiranye mu mezi 18 yo gukora mu nyanja yuzuye umunyu.
Kwinjira mu buryo butaziguye, ntabwo ari abagabuzi
Imishinga ya ASTM A747 isaba ibiganiro byubuhanga-ntabwo byateganijwe. Mugihe umudage wubushakashatsi bwa hydraulic valve yadusabye kwemeza geometrie ivuguruye-inzira ya geometrie, itsinda ryacu ryakoresheje amashusho yubushyuhe bwumuriro * mbere yo gukoresha ibikoresho, berekana ahantu hashyushye ahantu h’icyambu cya saa tatu, maze dusaba ko hahindurwa ubukonje bwaho. Ubwo bufatanye bwagabanije prototype yo kuyobora iminsi 22. Dukoresha ibisobanuro bya GD&T, gushushanya kwemeza, no gutanga ibitekerezo-ntabwo ari nk'inyongera, ariko nk'intambwe zisanzwe.
Ikigo cacu cyemewe na ISO 9001 muri Qingdao gikora B2B itaziguye gusa. Nta bakwirakwiza. Nta bahuza. Uravugana na injeniyeri utegura umusarani wa CNC ukata icyuma cya ASTM A747 - ntabwo ari ibicuruzwa biva mu gitabo cya PDF. Ibihe byambere byagenwe mugihe cyo gusubiramo: ibyumweru 12 kugirango yemeze ingingo ya mbere, ibyumweru 8 kubisubiramo-bifunze mu nyandiko, hamwe nibihano byo gutinda.
ASTM A747 ubufatanye bwuruganda bugenda neza mugihe metallurgie, gutunganya, hamwe no kubazwa bihuye. Niba ubutaha bwawe bwo gutoranya busaba ubunyangamugayo bwa cobalt-alloy - ntabwo ari urupapuro rwihariye - tangira ukurikirana ibintu, ugenzure inyandiko zivura ubushyuhe, kandi wemeze uwasinye kuri raporo yanyuma ya CMM. Itandukaniro hagati yubusobanuro bwubahirizwa hamwe numurima wizerwa ubaho murirambuye. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka itandukaniro muri buri gusuka.
