Pampu ya hydraulic ikalephera pansi pa 350-bar pressure, kapena cobalt-alloy nozzle imasweka pambuyo pa maola 800 akugwiritsa ntchito gasi wowawasa, mainjiniya samafunsa kuti "Ndani adapanga izi?" Iwo amafunsa kuti: "Ndani angakonze - ndikutsimikizira kuti sizichitikanso?" Funso limenelo limalekanitsa ogulitsa katundu ndi mabwenzi enieni. Pakatikati pa kusiyanitsa kumeneku pali kuthekera kumodzi: kusasinthasintha, kubwerezabwereza mwatsatanetsatane pamafakitale apadera a alloy - komwe zitsulo, geometry, ndi ntchito yofunika kwambiri zimakumana.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amasamalira zolephera zimenezo—osati monga zolakwika zoti ziwongoleredwe, koma monga zilolezo zowongolera njira zowongolera. Tawonapo AMS 5387 cobalt alloy pump housings ikugwedezeka panthawi ya kutentha pamene kuzizira kumadutsa 12 ° C / min. Tidayeza ma roller apakati a T800 omwe amataya 0.018 mm kuzungulira pambuyo pa ma torque 15,000 - kokha chifukwa chotulutsa choyambirira sichinagwirizane ndi chonyamula katundu. Awa si malire ongoyerekeza. Ndiwo gawo loyang'aniridwa lomwe limapanga chithunzi chilichonse chojambula, njira iliyonse yopangira zida, zowunikira zilizonse.
Mphamvu zinayi zimatsimikizira kudalirika kwawo-osati monga zotsatsa, koma monga zotulukapo zoyezeka:
- Cobalt-nickel mastery kupitilira ma datasheet. AMS 5387 sikuti ndi "yopanda dzimbiri." Kubalalika kwake kwa carbide kumasintha ndi mbiri yamafuta. Zoyambira zawo zimawongolera kuchuluka kwamphamvu mkati mwa ± 0.8 ° C / sec; maselo awo CNC ntchito zida cryo-utakhazikika kusunga umphumphu pamwamba m'munsimu Ra 0.4 µm pa bores anamaliza. Umu ndi momwe amaperekera mapulagi a aloyi a cobalt omwe amasindikiza pa 420 ° C popanda kupwetekedwa mtima - komanso chifukwa chake makasitomala ku North Sea amawafotokozera za ma valve a subsea.
- Kuphatikizika koyima komwe kumalepheretsa kusuntha kwa dimensional. Otsatsa ambiri akutulutsa, kukonza, ndikumaliza kwa ogulitsa atatu osiyanasiyana. Chilichonse chothandizira chimawonjezera kulolerana. QINGDAO QIANGSENYUAN amachita kuponyera mchenga, 5-axis mphero, mankhwala kuchepetsa nkhawa, ndi electropolishing mu malo amodzi ISO-certified. Nyumba ya silinda ya pampu ya piston imachoka kutsanuliridwa kwachitsulo mpaka kutsimikizika komaliza kwa CMM m'maola 72-palibe zinthu zakunja, palibe kusiyana kwa batch-to-batch. Kutsata sikunalembedwe; ndi laser-zozikika mbali iliyonse.
- Kutsimikizika kwapangidwe kogwira ntchito-osati kutsata kwa GD&T kokha. Makasitomala amatumiza zojambula. Akatswiri amayankha momveka bwino kuti: “Chamfer ya 0.05 mm imeneyi imatchera zinyalala m’tinjira tamadzimadzi—m’malo mwa 0.2 mm radius.” Kapena: "Kukhuthala kwakhoma komweko kumapangitsa kuti pakhale kuphatikizika kwamphamvu kwa 1,850 rpm. Onjezani nthiti apa." Izi sizotsutsa. Ndikuchita uinjiniya kutengera zaka 12 zakulephera kusanthula pama hydraulic, pampu, ndi makina opambana.
Ena amatsutsa kuti ntchito yapadera ya alloy imafuna kuyandikana kwa madera - "Mumafunikira mainjiniya pamalopo kuti musinthe ma feed munthawi yeniyeni." Koma kusintha kwa nthawi yeniyeni kumachitika musanayambe kudula. Mapulogalamu awo opanga makina ofananirako amapangidwa ndi chip mu T800 alloy pamakona osiyanasiyana opangira, kuneneratu kuvala kwa zida mkati mwa 3% ya moyo weniweniwo. Pamene kasitomala waku Europe amafunikira mavavu 220 osakhazikika m'masabata 11, botolo silinali lokwanira - kunali kutsimikizira kufanana kwa microstructure kudutsa ma 16 castings. Yankho lawo? Pamalo a metallography labu + makina odzipangira okha a EDS. Magawo aliwonse adadutsa kutsimikizira kukula kwambewu ya ASTM E112 asanayambe kupanga makina ovuta.
Chilangochi chimakulirakulira—koma kokha pamene zinthu zofunika kwambiri zimakhazikika. Sathamangitsa voliyumu. Amakonzekera kubwereza: wogwiritsa ntchito yemweyo, makina omwewo, ndende yoziziritsa yomweyi, kuzungulira komweko koyeretsa pambuyo pokonza. Ndicho chifukwa chake mapangidwe awo a zitsulo amakwaniritsidwa mosasinthasintha 780 MPa ± 12 MPa - osati "mpaka 780 MPa." Chifukwa chiyani maziko awo a pampu yachitsulo chosapanga dzimbiri amakhala ndi kutsika mkati mwa 0.03 mm kupitilira 600 mm - kutsimikiziridwa ndi laser tracker, osati CMM yokha. Chifukwa chiyani ma nozzles awo a cobalt alloy amapulumuka ma 14,000 matenthedwe matenthedwe mumagetsi obwezeretsa zinyalala popanda microcracking.
Fakitale yapadera ya zigawo za alloy imapangitsa kuti anthu akhulupirire osati mwa kulonjeza ungwiro-koma mwa kulemba ndendende kumene kupanda ungwiro kukukhala, kenaka kupanga zomangamanga mozungulira. QINGDAO QIANGSENYUAN TECHNOLOGY sichimabisa kusinthasintha. Amayiyika: ma gradient otenthetsera mu nkhungu zoponyera, zida zosokoneza zida mu mphero yakuya m'thumba, mitengo ya hydrogen pakupanga ma electropolishing. Malipoti awo abwino samalemba kupitilira / kulephera. Amawonetsa ma delta motsutsana ndi ma curve oyambira - kotero makasitomala amawona osati *ngati* gawo likukumana ndi zina, koma *kuchuluka kwa malire kumatsalira* musanafike malire.
Tsogolo silili la makina akuluakulu kapena ma spindle othamanga. Zimatengera kusinthasintha kwa mayankho pakati pa magwiridwe antchito ndi magawo azinthu. Pakali pano, gulu lawo la R&D likulumikiza siginecha zogwedezeka kuchokera ku ma roller a winch center shaft omwe ali ndi mamapu otsalira opsinjika kuchokera pamasikidwe awo a XRD. Chaka chamawa, zidziwitsozo zidzayendetsa njira yosinthira zida - makina osatengera milingo mwadzina, koma kutengera mbiri yoloseredwa yantchito. Ndipamene kudalirika kumasiya kukhala chandamale-ndipo kumakhala zotsatira zoyezeka.
