Pamene mainjiniya amafunikira a fakitale yotaya sera pazigawo zomwe ziyenera kukhala ndi ± 0.02 mm tolerances pansi pa 350-bar hydraulic pressure, samatchula zoyambira. Amayitanira mashopu okhala ndi zipika zamafuta a cobalt alloy pafayilo, malipoti a CMM osindikizidwa ndi owerengera a ISO 9001, komanso amatumiza nyumba zapampu za AMS 5387 kwa opereka chithandizo chamafuta a Tier-1 ku Houston ndi Aberdeen. Ndicho chenicheni cha ntchito-osati chinenero cha malonda.
Chifukwa Chiyani “Mwambo” Umatanthauza Zambiri Kuposa Sitampu Yojambulira
Kutaya sera si mwambo chifukwa mumatumiza fayilo ya STEP. Ndi chizolowezi pamene foundry amasokoneza chiwopsezo cha mapangidwe asanayambe kugwiritsa ntchito. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tawonapo mfundo zitatu zolephera mobwerezabwereza pamapangidwe a thupi la valve omwe amaperekedwa ndi kasitomala: choyamba, zigawo zoonda kwambiri za khoma pansi pa 4.2 mm zomwe zimang'ambika panthawi yopuma kupsinjika maganizo; chachiwiri, akhungu mkati radii pansi R1.5 kuti msampha ceramic zipolopolo zotsalira; Chachitatu, ma callouts a GD&T akuwonetsa mbiri yapamtunda popanda kufotokozera kutsogola kwa datum-kuyambitsa kusalumikizana bwino pamapampu a piston. Timayimitsa izi panthawi yowunikira mainjiniya - osati pambuyo pokana. Umu ndi momwe "mwambo" umakhalira kuwonetseratu, osati kuchitapo kanthu.
Real-World Alloy Handling, Osati Zonena Za Mapepala
Ma aloyi a cobalt-nickel ngati T800 ndi AMS 5387 samapangidwa - amakopeka. Kutentha kwawo ndi 1/6th ya 304 zosapanga dzimbiri. Mlingo wawo woumitsa ntchito umakwera pambuyo pa 0.15 mm wakuzama wodulidwa. Choyikapo chokhazikika cha carbide chimasweka pakukhudzana koyamba. Timagwiritsa ntchito zida za ceramic zokutidwa ndi PVD, zoziziritsira madzi osefukira pa 42 bar pressure, ndikuchepetsa kuya kwa axial mpaka 0.08 mm podutsa. Izi si chiphunzitso. Ichi ndichifukwa chake ma nozzles athu a aloyi a cobalt amakhala ndi moyo kwa miyezi 18 pamapampu othamanga kwambiri pomwe opikisana nawo amalephera miyezi isanu. Timatsata kuuma kwa batch iliyonse, kagayidwe kake, ndi kagayidwe kake - chifukwa microstructure imapangitsa moyo wotopa, osati kulimba kwamphamvu.
Kuphatikiza Koyima Mutha Kuyeza
Othandizira ambiri amapangira kunja, kukonza, kapena kumaliza. Izo zimapanga dimensional kutengeka. Kutsika kwapatani ya sera sikufanana ndi kuvala kwa CNC. Kuwonongeka kwa kutentha sikulipidwa pakugaya komaliza. Pamalo athu a Qingdao, gulu limodzi lili ndi unyolo wonse: kuyika ndalama → kuchepetsa nkhawa → 5-axis CNC contouring → zokutira za HVOF → kuyezetsa kutayikira. Pa nyumba ya silinda ya pampu ya piston, izi zikutanthauza kuti kutha kwathunthu kumakhala pansi pa 0.015 mm kudutsa 320 mm kutalika-kutsimikiziridwa ndi laser tracker, osati CMM yokha. Palibe ma handoffs. Palibe masewera olakwa. Kuwongolera ndondomeko yongotsatiridwa kuchokera ku jekeseni wa sera kupita ku lipoti lomaliza loyendera.
- Zopangira zida zotsimikizika ku ASTM A975 / AMS 5737 zokhala ndi malipoti athunthu oyesa mphero
- Macheke amkati: kutsimikizira makulidwe a zipolopolo, kuwunika kwa mawonekedwe a sera, kulimba kwa mapu a mankhwala asanatenthedwe
- Kutsimikizira komaliza: kuyezetsa kwa helium kutayikira ku 1 × 10⁻⁹ mbar · L/s, roughness pamwamba Ra ≤ 0.8 μm pankhope zovuta kuzisindikiza, kukana kwa utsi wa mchere ≥ maola 1,000 pa ASTM B117
Zimene Makasitomala Amafunikira—Osati Zimene Timabuku Timalonjeza
Oyang'anira zogula amafunsa mafunso atatu-ndipo amapeza mayankho osamveka kwinakwake:
"Kodi mutha kukhala ndi malo enieni pamabowo asanu ndi limodzi a Ø8.5 mm mkati mwa 0.01 mm mpaka padamu yokhazikitsidwa pamalo oponyedwa?" Inde—ngati ngodya yoponyamo ndi ≥ 1.2° ndipo malo a datum amapangidwa mopanda phokoso asanabowole dzenje. Tikuwonetsani kapangidwe kake.
"Kodi nthawi yanu yotsogolera ndi yotani pazidutswa 12 za pulagi ya AMS 5387 yokhala ndi ulusi wosakhazikika?" Masiku a 28 kuchokera pakulandila chilolezo. Osati "masabata 4-6." Osati "kutengera kupezeka kwa zinthu." Timasunga ma billets a T800 ndikusunga mapangano amitundu iwiri ndi ogulitsa ma cobalt awiri ovomerezeka ndi AMS ku China ndi Germany.
"Kodi mumathandizira PPAP Level 3 pamakina oyendetsa magalimoto?" Inde-ndi zolemba zonse za DFMEA, zojambula zamayendedwe, ndi maphunziro a MSA pazovuta zonse. Osati ndandanda chabe.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pomwe zigawo zachitsulo zolondola zimakumana ndi zotsatira zenizeni. Winch center shaft roller ikalephera pa crane yakunyanja, nthawi yotsika imawononga $220,000/ola. Pamene valavu yoponderezedwa imalowa mu gawo lolamulira la subsea, m'malo mwake kumafuna ROV kulowererapo pa 2,800 mamita. Palibe malo oti "pafupi mokwanira." Ichi ndichifukwa chake makasitomala amabwerera-osati pamtengo, koma chifukwa chotsimikizika, kusasinthasintha kwazitsulo, ndi mgwirizano waumisiri wophikidwa muzolemba zilizonse. Nthawi ina mukadzafotokoza za kupanikizika kwambiri, kuvala kwambiri, kapena kuwononga dzimbiri, yambani ndi kupanga - osati geometry yokha. Cholinga chanu chodalirika chimadalira.
