Pamene nyumba ya pampu ya hydraulic imaphwanyidwa pansi pa 350-bar pressure-kapena cobalt alloy nozzle imalephera pambuyo pa maola 420 a ntchito ya gasi wowawasa-vuto silimangolephera. Ndiko kusweka kwa unyolo pakati pa zolinga zamapangidwe ndi zenizeni za metallurgical. Mpata umenewo ndi pamene kulondola zitsulo zopangira zida amapeza kulemera kwake-osati ngati njira yamalonda, koma monga njira yoyendetsedwa, yotsogoleredwa ndi sayansi ya chiweruzo cha uinjiniya.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tawona izi zikusewera ma projekiti 178 a OEMs aku North America oilfield, ophatikiza ma hydraulic system integrators, ndi omanga mapampu am'madzi aku Southeast Asia. Makasitomala m'modzi adatitumizira zojambula zolemera za GD&T za nyumba ya silinda yapampu ya AMS 5387-yolimba kwambiri: ± 0.015 mm pa ID bore, kumaliza pamwamba Ra ≤ 0.8 µm, zero porosity mkati m'malo ovuta kwambiri. Wowagulitsa m'mbuyomu adapereka magawo 12. 3 okha anadutsa akupanga kuyezetsa. Tidayendetsa kayeseleledwe kokwanira koyamba: kulimbitsa mafanizidwe, mapu otenthetsera ma gradient, kukhathamiritsa kwa gating. Kenako, kuponyera, kutentha, CNC-kutha, ndi CMM-kutsimikizira gawo lililonse. Onse 24 anadutsa. Kusiyana sikunali mwayi. Anali kupereka chilango chosakanikirana ndi makina owongolera.
Kulondola kwenikweni zitsulo zopangira zida imayamba nkhungu isanakhudze mchenga kapena ceramic. Zimayamba ndi kuyankha pazachuma. Timatulutsa ma aloyi a cobalt-nickel okha kuchokera ku mphero zomwe zimapereka malipoti otsimikizika a kutentha-AMS 5387, UNS R30006, T800-grade-yomwe imatha kusungunuka, kusanthulanso mankhwala, ndi kutsimikizira kukula kwambewu. Palibe "mavareji amagulu." Palibe ziphaso zoperekedwa ndi ogulitsa popanda macheke a chipani chachitatu. Pamene opanga ma valve ku Europe amafunikira mapulagi a cobalt a 19mm-diameter kuti agwiritse ntchito H₂S, adatitumizira mawonekedwe awo a ASTM A995 Level II-ndipo tidafanizira mpaka 0.03% kupatuka kwa kaboni. Kukhulupirika kumeneku sikumachitika m'masitolo omwe amasankha kusankha kwa alloy ngati bokosi.
Kuphatikizika koyima sikuli nkhani yotsatsa apa-ndimo momwe kukhazikika kumatsekerezedwa mkati. Kuponyera mchenga kokha sikungagwire ± 0.02 mm pa maziko a mpope a 320-mm-utali. Ngakhalenso makina a CNC okha sangathe kuwongolera kutsika kwapang'onopang'ono muzitsulo zazitsulo za aloyi. Koma poponya, kutentha, ndi mphero ya 5-axis zimachitika pansi pa denga limodzi - ndi metrology yogawana, mazenera olumikizana, ndikuwunikanso kwa GD&T - zolakwika zowunjika zimagwa. Nthawi zonse timagwira 0.008 mm flatness pazitsulo zosapanga dzimbiri zoyezera 420 × 280 × 95 mm-pambuyo pochepetsa nkhawa, kusokoneza, kutsirizitsa, ndi kutembenuka komaliza. Izi zimafuna malipiro enieni a nthawi yeniyeni pa CNC, osati kukonzanso pambuyo pa ndondomeko.
- Palibe "black box" akuponya: Chitsulo chilichonse kapena chitsulo choponyera chitsulo chimadutsa muzitsulo zolimba; Gawo lililonse la cobalt alloy limapeza kutsimikizika kwapang'onopang'ono kwa microstructure kudzera pa optical emission spectroscopy + SEM malo macheke
- Palibe makina akhungu: Zambiri za CMM zochokera kuzinthu zopanda kanthu zimadyetsa mwachindunji kukhathamiritsa kwa zida za CNC-kuchepetsa kuchotsa katundu mpaka 37% panyumba zovuta.
- Palibe QA yamapepala okha: Kutsatiridwa sikulowa mu database. Ndi tag yakuthupi yojambulidwa ndi laser pagawo lililonse, yolumikizana ndi ma certs, malipoti a NDT, zipika zochizira kutentha, ndi zithunzi zomaliza zoyendera.
Ena amaganiza kuti kusungitsa ndalama kumakhala kolondola kwambiri kuposa kuponya mchenga. Osati zoona. Chigoba chosasamalidwa bwino chimasokoneza nthawi ya dewaxing. Chikombole chamchenga chothamanga chimazizira mosiyanasiyana, kumapangitsa kuti pakhale kupsinjika komwe kumazungulira pakukonza. Chofunika kwambiri ndi nzeru zamachitidwe—osati mtundu wa nkhungu. Timagwiritsa ntchito zopangira mchenga pazigawo zazikulu, zocheperako monga zodzigudubuza za injini yagalimoto ya winch center shaft (mpaka 1,200 kg), chifukwa kuziziritsa kolamuliridwa ndi ma prints opangidwa ndi injiniya kumapereka kulimba kolimba kwambiri kuposa kuyika ndalama m'magawo okhuthala. Kwa timphuno tating'ono tating'ono ta cobalt? Ndalama zimapambana-koma kokha ndi kuthira kothandizidwa ndi vacuum komanso kuwongolera kokhazikika. Kukonzekera sikuphikidwa mu njira. Zimapangidwa muzosankha zilizonse.
Yang'anani m'tsogolo: Malire otsatirawa si ng'anjo zazikulu kapena masipiko othamanga a CNC. Ndiko kuwongolera njira zosakanizidwa - komwe zotulutsa zoyeserera zimadyetsa mitundu yotentha m'malo opangira makina, pomwe masensa a in-situ amasinthira zida zapakati, pomwe mapasa a digito amatsimikizira moyo wotopa asanayambe kuthira koyamba. QINGDAO QIANGSENYUAN TECHNOLOGY ikupanga lusoli tsopano-osati ngati kuyesa labu, koma monga zomangamanga zopangira. Tikutsimikizira ku AS9100 pazigawo zofunika kwambiri zakupopa mumlengalenga. Tikuyenerera HIP (kukankhira kotentha kwa isostatic) kwa pafupifupi cobalt castings. Ndipo timaphunzitsa akatswiri osati kungowerenga mapulani-koma kulosera momwe chitsulo chosungunula chidzachitira mu geometry yeniyeni, pansi pazikhalidwe zozizira zomwe zimadziwika, ndi chemistry yotsimikiziridwa ya alloy.
Kuponyera zitsulo zoyambira sikutanthauza kuthira zitsulo mu mawonekedwe. Zimakhudza kutanthauzira kufunidwa kwa magwiridwe antchito - kukhulupirika kokakamiza, kukana kuvala, kukhazikika kwamafuta - kukhala chitsimikizo chazitsulo. Izi zimafuna zambiri kuposa zida. Imafunikira chidziwitso ndi mitundu ya AMS 5387 yosweka. Imafunikira ukadaulo wazowongolera zoyendetsedwa ndi GD&T. Imafunika kudalirana kokhazikitsidwa pakupanga kovomerezeka kwa 217, osati malonjezo. Ngati nyumba yanu yotsatira yothamanga kwambiri ya valve, chigawo cha pampu ya piston, kapena gawo lapadera la alloy likuyenera kuchita-osati kungopulumuka-ndiye kuti kulondola kumayamba kalekale kuyambika koyamba kusanagwire ntchito.
