Stellite 6 sikuti ndi aloyi wina wopangidwa ndi cobalt - ndizomwe akatswiri amafikira pomwe kulephera sikungatheke. M'nyumba zapampopi za hydraulic zomwe zikuyenda pa bar 420, mumipando ya ma valve otsika pansi pa gasi wowawasa wodzaza mchenga, kapena ma roller othamanga kwambiri pamitsuko ya migodi, Stellite 6 imapereka kukana kovala komwe kumapitilira zitsulo zosapanga dzimbiri ndi 5-8×. Koma kupeza izo modalirika? Ndiko kumene ogula ambiri amaima. Tawonapo oyang'anira zogula akukana mawu atatu tisanazindikire: kutsekereza sikuli mtengo-ndikufanana kwazitsulo, kubwerezabwereza, komanso kutsata kwa AMS 5387. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timapanga makina, kuponyera, ndikumaliza magawo 6 a Stellite tsiku lililonse-osati ngati zinthu zamabuku, koma monga njira yolangirira yomwe idakhazikitsidwa zaka 12 za hydraulic ndi oilfield chigawo ntchito.
Chifukwa chiyani voliyumu yofufuzira ya "Stellite 6" idakwera - komanso tanthauzo lake
Mafunso a "Stellite 6 fakitale" adakwera 68% YoY pamapulatifomu opangira mafakitale - oyendetsedwa ndi mainjiniya atatopa ndi kukonzanso kuchokera kuzinthu zina zamtundu wa cobalt alloy. Makasitomala m'modzi adatumizanso magulu asanu ndi limodzi a AMS 5387 piston grooves chifukwa kulimba kumasiyana kuchokera pa 42 mpaka 49 HRC pamaere. Mabotolo ena 22 ophwanyidwa pambuyo pong'ambika pang'ono adawonekera panthawi yotentha - kutengera kugawanika kwa carbide kosagwirizana ndi zinthu zoyambira. Izi siziri zochitika zenizeni. Ndizizindikiro zaunyolo wogawikana: amalonda omwe amapeza malo ogulitsira ambiri osungunula, ma broker omwe amalowetsa zinthu zosavomerezeka za T800, kapena ogulitsa omwe ali ndi zida popanda zolemba zochizira kutentha. A zoona Stellite 6 fakitale Ayenera kuwongolera ma levers anayi panthawi imodzi: kutsimikizira kwaiwisi yaiwisi yaiwisi, kuwongolera kutentha kwamphamvu, kukonza bwino kwa zinthu zolimba (Rockwell C 44-48), ndi kutsimikizira kukhulupirika kwapambuyo. Timachita zonse zinayi mu malo amodzi a ISO 9001 ku Qingdao.
Palibe kunyengerera pazitsulo - kuyambira ndi AMS 5387 traceability
Timapeza ma billets a Stellite 6 okha kuchokera ku mphero zokhala ndi satifiketi ya AMS 5387 -ndikusunga malipoti oyesa mphero, manambala a kutentha, ndi kusanthula kwamitundu pamaoda aliwonse. Chifukwa chiyani? Chifukwa kusintha kwa mpweya wa ± 0.03% kumasintha kagawo kakang'ono ka carbide mpaka 15%, zomwe zimakhudza mwachindunji kukana kwa ma abrasion pamapampu onyamula slurry. Gulu lathu lotulutsa limagwiritsa ntchito ukadaulo wopangira ma geometries ovuta monga ma multi-orifice cobalt alloy nozzles, kenako ndikuyika njira yothawira pawiri (1175 ° C + 1050 ° C) yotsatiridwa ndi kuziziritsa kwa mpweya - kupewa gawo la brittle sigma lomwe limapanga magawo oziziritsidwa pang'onopang'ono. Pazigawo zamakina, timagwiritsa ntchito nsanja zolimba za 5-axis CNC zokhala ndi zoyika za ceramic ndi kutumiza koziziritsa kukhosi. Izi sizongowonjezera-ndimo momwe timagwirizira ± 0.015 mm kulolerana pa 32-mm-diameter pakati shaft rollers kwinaku tikusunga roughness pansi pa Ra 0.4 µm.
Kuphatikiza koyima kumathetsa zomwe ogawa sangathe
Ena ogulitsa amagulitsa mipiringidzo 6 ya Stellite. Ena amawapanga makina. Ochepa amagwiritsa ntchito kuponyera, chithandizo cha kutentha, kupukuta molondola, ndi kuyesa ntchito pansi pa denga limodzi. Komabe kuphatikizikako sikungakambirane pazigawo zofunika kwambiri zautumwi. Pamene European OEM inkafuna ma silinda olowa m'malo a mapampu amphamvu kwambiri a triplex, wogulitsa wawo wakale adapereka magawo okhala ndi subsurface porosity - osazindikirika mpaka kuyesa kwa hydraulic pa bar 350 kudadzetsa ngozi yotuluka. Tidayesa kumiza kwa akupanga pakuponyedwa kulikonse, kenako kutsimikiziridwa kudali kokhazikika ndi kuyang'ana kwa mpweya pa ndege zitatu za axial. Chotsatira? Zolephera za zero pa maola 17,000 ogwirira ntchito. Mayendedwe athu amachotsa ma handoffs: kuwunika kwa mapangidwe → kutulutsa zinthu → kuponyera → kutentha kwa kutentha → CNC → kutsimikizika kwa CMM → kuyesa komaliza. Nthawi yotsogolera imatsika 30%. Kukonzanso kumagwera <0.7%.
Zochitika zenizeni padziko lapansi-osati malonjezo a data
- Ma valve opanikizika: Kuyika mipando ya Stellite 6 kupulumuka kuzungulira kwa 1.2 miliyoni mumayendedwe a jakisoni wamadzi amchere pomwe 316 zosapanga dzimbiri zimalephera kuzungulira 210,000
- Nyumba zapampu za piston: Zibowo zolimba kwambiri zimasunga ≤0.008 mm ovality pambuyo pa maola 8,000 pa 200 ° C ndi 400 rpm
- Winch center shaft rollers: Imani kunyamula katundu wokulirapo wa matani 15 popanda kupwetekedwa mtima—ngakhale pambuyo pa maola 3,500 mumchenga wonyezimira wa m’chipululu
Sititchula "standard" Stellite 6. Timabwereza wanu kugwiritsa ntchito: liwiro lamadzimadzi, kukula kwa tinthu, mbiri yapanjinga yotentha, ndi moyo wofunikira wofunikira. Ichi ndichifukwa chake gulu lathu la mainjiniya limawunikanso mawu a GD&T musanatchule - osati pambuyo pake. Ngati chojambula chanu chikuwonetsa kuthamanga kwa 0.005 mm pa nkhope ya flange ya 120-mm-diameter, timafanizira kupatuka pasadakhale ndikusintha njira yokhomerera. Ngati mpope wanu umagwira ntchito modukizadukiza ndi kutentha kofulumira, tikupangira kuti muchepetse kupsinjika kwapambuyo pa makina pa 650°C—ngakhale itawonjezera maola 12. Chifukwa moyo wautali sunayesedwe m'miyezi. Zimayesedwa mu nthawi yowonjezera, kuchepetsa gawo lopuma, ndikupewa mtengo wotseka.
Stellite 6 imagwira ntchito pokhapokha zitsulo zake, geometry, ndi mawonekedwe ake akugwirizana bwino. Kuyanjanitsa kumeneko kumayamba - osati ndi dongosolo logulira - koma ndi fakitale yomwe imagwiritsa ntchito ma aloyi a cobalt monga dongosolo, osati katundu. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imapanga dongosolo ili mu gawo lililonse. Kwa mainjiniya omwe amayesa kuchita bwino pakati pa zolephera - osati pamtengo wotsika kwambiri wa unit - the Stellite 6 fakitale zomwe mukufunikira zasinthidwa kale, zatsimikiziridwa, ndikukonzekera gawo lanu lotsatira.
