Mainjiniya akafuna zida zachitsulo zolondola zomwe zimapulumuka ma 30,000 psi hydraulic cycles kapena 650 ° C kutulutsa mpweya wotulutsa mpweya, samayamba ndi generic foundry. Iwo amayamba ndi a fakitale yotaya phula yotayika yomwe imagwira ntchito za cobalt alloy nozzles ngati zida zopangira opaleshoni-ndipo imadziwa bwino momwe mbewu ya AMS 5387 imayankhira kugwedezeka kwa kutentha panthawi ya dewaxing.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ndi fakitale imodzi yotere. Osati broker. Osati kampani yamalonda. Kugwira ntchito, kogwirizana ndi ISO ku Qingdao komwe akatswiri azitsulo amasinthira kukhuthala kwa slurry kutengera chinyezi chozungulira - ndipo akatswiri amakasitomala amazimitsanso ziro zopota za ma axis asanu asanadule ma T800 a cobalt pamakina akunyanja. Tawona makasitomala akutaya milungu itatu ndi $ 18,000 pakukonzanso chifukwa omwe adawatumizira adalumpha kutsimikizira kwa GD&T kusanachitike. Pamalo awa, chiwopsezo cham'mbali chimagwidwa chisanadze phula loyamba kulimba.
Njira yawo yotayira phula yotayika sikungokhala "kuponya ndalama". Ndi dongosolo lolumikizidwa mwamphamvu: kutsatiridwa kwa zinthu zopangira zovomerezeka → kupangidwa kwa zipolopolo za ceramic zomwe zakonzedwa kuti ziwonjezeke matenthedwe a aloyi → mitengo yowongoka yowongoka → kuthira kothandizidwa ndi vacuum kwa ± 5 ° C kulolerana → mpumulo wa post-cast stress wosinthidwa kukhala AMS 2750E standards. Kwa mavavu oponderezedwa kapena ma silinda a pampu ya pistoni, izi zikutanthauza kuti makulidwe a khoma amakhala pansi pa ± 0.15 mm-ngakhale pa ma 420 mm OD oponyera okhala ndi njira zozizirira zamkati. Palibe zongoyerekeza. Palibe kusuntha kwa batch-to-batch. Malo aliwonse otentha amakhala ndi malipoti athunthu ndi ziphaso zoyeserera.
Nchiyani chimawalekanitsa iwo kuchokera ku standard foundries? Zowona zitatu zogwirira ntchito:
- Chilango cha alloy - osati luso chabe. Iwo "sagwira" ma aloyi a cobalt-nickel. Amayendetsa ng'anjo zodzipatulira za AMS 5387, zokhala ndi ma crucibles, ladles, ndi ma protocol a slag kuti apewe kuipitsidwa ndi magiredi osapanga dzimbiri. Makasitomala akatumiza chojambula cha pulagi ya cobalt alloy yosakhazikika yokhala ndi kulolerana kwa 0.05 mm pamadoko asanu ndi limodzi, gululo silinatchule mwachimbulimbuli. Anayendetsa msonkhano wa sera, kutsimikizira kuyika kwa zipata pogwiritsa ntchito mayendedwe othamanga, ndikutsimikizira nthawi yamoto ya zipolopolo - asanavomereze PO.
- Palibe ma handoffs pakati pa kuponyera ndi Machining. Otsatsa ambiri amatulutsa CNC ntchito pambuyo poponya. Apa, mainjiniya wamtundu womwewo amasainanso pomaliza (Ra ≤ 3.2 μm) ndi datum yomaliza (CMM-yotsimikiziridwa mpaka ± 0.01 mm). Izi zimachotsa zolakwika zosungirako potembenuza chotchingira maziko a pampu ndikukhazikika pakukhazikitsa kumodzi - kofunikira pa kukhulupirika kwa hydraulic seal.
- Chidziwitso cha kulephera kokhazikitsidwa mu sitepe iliyonse. Pazitsulo ndi zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito pazida zamafuta ndi gasi, amawunika momwe madzi amalowera *ataphulitsa* kuwomberedwa koma *asanapange* makinawo - kugwira porosity ya micro-shrinkage yomwe kugaya kungabisike. Ngati gawo la aloyi la T800 likuwonetsa ma subsurface oxide inclusions pansi pa ultrasound scan, imachotsedwa - osati "kukonzedwanso." Chifukwa m'mapulogalamu ofunikira kwambiri, "zabwino mokwanira" zimalephera mwakachetechete - komanso mowopsa.
Ena angatsutse kuti kuponya mchenga kumapereka kusintha kwachangu pazitsulo zazikuluzikulu zachitsulo. Koma gawolo likakhala chowongolera cha winch center shaft roller chomwe chimagwira ntchito pansi pa cyclic torsional load, kukhulupirika kwa geometry kumafunika kwambiri kuposa kuthamanga. Sera yotaika imapereka mawonekedwe oyandikira ukonde okhala ndi makoma opanda zolembera, ndikuchotsa makina achiwiri pazipinda zolimba. Ndipo inde - zimawononga ndalama zambiri zam'tsogolo. Koma kasitomala m'modzi adachepetsa mtengo wokwanira pa valavu ndi 22% atasintha: misonkhano yokanidwa yocheperako, kutayikira kwa ziro, ndi moyo wautali wautumiki kuchokera pa miyezi 14 mpaka miyezi 36+ m'malo amchenga.
Izi sizongoyerekeza. Ndizobwerezabwereza. Malo awo opangira amayendetsa machitidwe oyenda bwino - osati monga mawu, koma monga machitidwe a tsiku ndi tsiku. Prototypes imatumizidwa m'masiku 12 ogwira ntchito. Malamulo apakati (ma PC 50-500) amakhala ndi mazenera otumizira masiku ± 3-otsimikizika polemba. Kuwongolera pulojekiti kumaphatikizapo kujambula mu nthawi yeniyeni, kuthetsa mikangano ya GD&T, ndi mayankho opangira zinthu mkati mwa maola 48 kuchokera pakupereka RFQ. Palibe mawu amtundu wakuda. Ayi, "tidzazindikira pambuyo pake." Kungogwirizanitsa uinjiniya kuyambira tsiku loyamba.
Kuyang'ana m'tsogolo, kuyang'anako kumanola: kuzama kwa R&D munjira zosakanizidwa zopangira makina opopera zokhala ndi mipanda yopyapyala kwambiri, ziphaso zokulitsidwa kuti zivomerezedwe ndi zinthu zamlengalenga, komanso kuphatikiza kolimba kwa kujambula kwamafuta panthawi yowombera zipolopolo. Koma chiyambi sichinasinthe - tanthauzo lawo la chowonadi fakitale yotaya phula yotayika sizikukhudzana ndi zida zankhondo. Ndi za kukhala ndi zotsatira za micrometer iliyonse, kuphatikiza kulikonse, kutentha kulikonse. Chifukwa chakuti gawo lanu likamatsekereza magaloni 5,000 a madzi a m’nyanja—kapena kuwongolera kayendedwe ka mafuta mu turbine—fakitale imene mwasankhayo sipereka zitsulo. Zimapereka chidaliro.
