Mainjiniya akanena za mphamvu yokoka zoponyera ma valve opangira ma hydraulic kapena nyumba zopopera zopatsirana kwambiri, sikuti amangogula zitsulo - amathandizira kuti pakhale bata pansi pa 300+ bar, kukhulupirika kwapang'onopang'ono pambuyo pochiza kutentha, komanso kutha kwa nthaka komwe sikungawononge dzimbiri m'madera odzaza mchere. Chifukwa chake a mphamvu yokoka kufa kuponya mbali fakitale ayenera kuchita zambiri kuposa kutsanulira zitsulo zosungunuka mu nkhungu zachitsulo. Iyenera kuwongolera mitengo yolimba mkati mwa ± 2 ° C, kutsimikizira kuyenderera kwa tirigu ndi kuyezetsa kwa akupanga, ndikusunga kulekerera kwa GD&T molimba kuposa ISO 2768-mK-makamaka poponya ma aloyi a cobalt-nickel ngati AMS 5387 kapena T800.
Chifukwa Chimene Gravity Imafa Kuponyedwa Kumafunikira Kuphatikizika Koyima—Osati Zoumba ndi Zitsulo Zosungunuka
Zolephera zambiri m'zigawo zoyendetsera ntchito zambiri zimabwereranso ku chifukwa chimodzi: kukonza ma handoffs. Woyambitsa amapanga gawo. Malo ena ogulitsira makina amabowola madoko ozizira. Wogulitsa wina amagwiritsa ntchito zokutira za HVOF. Kusamutsa kulikonse kumakhala pachiwopsezo chosokonekera, kusokonekera kwamafuta, kapena masinthidwe azinthu zopanda zikalata. Tawonapo nyumba zitatu za silinda za pampu ya pistoni zitakanidwa pamsonkhano womaliza - osati chifukwa cha porosity, koma chifukwa kuya kwa mpando wa valve wopangidwa ndi makina a CNC kumasiyana ndi 0.018 mm m'magulu chifukwa cha kusagwirizana kwa malo osungira.
Ndicho chifukwa chake kulondola kwenikweni kumayambira kusanatsanule koyamba. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., opanga ndi kupanga makina amagawana labu yofanana ya metrology, kutsatira zinthu zomwezo, ndi njira zoyendera zomwezo. Tikaponyera thupi la valve mu ASTM A494 CW6MC, CMM yomweyi imatsimikizira zonse zomwe zili ngati-cast cavity geometry * ndi * chosindikizira chomaliza chosindikizira - pogwiritsa ntchito maziko a granite okhazikika omwewo, kafukufuku wofanana, wofanana ndi GD & T. Palibe kukonzanso. Palibe kumasulira kwadongosolo. Kungotsatiridwa mosalekeza kuchokera kuzitsulo zamadzimadzi kupita ku gawo logwira ntchito.
Izi sizongoyerekeza. Umu ndi momwe timaperekera zodzigudubuza za winch center shaft zamagalimoto opangira uinjiniya omwe amagwira ntchito pa -40°C mpaka +85°C mozungulira, molimba mtima wa HRC 58–62 utali wonse wa mita 1.2—ngakhale mawonekedwe ake odzigudubuza amapangitsa makulidwe osafanana a khoma ndi kuzizirira kosafanana.
Kumene Ma Foundries Okhazikika Amayimitsira-Ndipo Chifukwa Chake Cobalt Alloys Amafunikira Zambiri
Opanga ena amatengera mphamvu yokoka ya cobalt ngati "aloyi ina." Lingaliro limenelo limalephera mofulumira. T800 ndi AMS 5387 sizikhala ngati aluminiyamu kapena zitsulo zosapanga dzimbiri. Kutentha kwawo ndi 1/5 ya 304 yopanda banga. Kutsika kwawo kolimba ndi 3.2%, osati 1.8%. Ndipo kutentha kwawo kumakwera pamwamba pa 1,250 ° C - pomwe ambiri amafa kutentha kwa preheat kumakhala.
Timasinthira izi munthawi yeniyeni: kutentha kwa nkhungu komwe kumasungidwa pa 320 ° C ± 5 ° C (osati 250-400 ° C), gating yopangidwira kuyenda kwa laminar pansi pa 0.8 m / s, ndi zokwera zokwera pogwiritsa ntchito kayeseleledwe kolimba-osati kulamulira kwa chala chachikulu. Kuponyedwa kulikonse kwa cobalt alloy annealing annealing post-cast annealing pa 1,180 ° C kwa maola 4, kenako madzi amazimitsidwa mkati mwa masekondi 15 - nthawi ndi ma pyrometer a mafakitale, osati nthawi. Patuka ndi masekondi 30? Ma carbides amtundu wa tirigu amakwera. Kulephera kuyesa kukula kwambewu ya ASTM E112. Chotsani mtandawo.
Makasitomala amafunsa kuti: "Kodi mutha kuponya geometry yathu yosakhala wamba mu AMS 5387?" Timayankha ndi deta-osati malonjezo. Timawawonetsa mapu otentha kuchokera ku MAGMASOFT® kayesedwe kathu, makina enieni a CMM a njira yozizirira yamkati ya prototype, ndi mbiri ya Rockwell C ya kuuma kwa nsonga ya 2-mm-thick. Ngati sichingafanane ndi kuyesa koyamba, timakonzanso kapangidwe kake - osati kujambula.
Kodi "ISO-Compliant" Imatanthauza Chiyani Pansi Pansipa
Chitsimikizo cha ISO 9001 chimakhala pakhoma. Chofunikira ndi zomwe zimachitika pa benchi. Pamalo athu a Qingdao, gawo lililonse lamphamvu yokoka limayesedwa kodziyimira pawokha katatu: kutsimikizira kwazinthu zopangira (spectrometry + tensile bar test), cheke mkati mwa 30% ndi 70% kumaliza (CMM + Optical comparator), ndi kutsimikizira komaliza kogwira ntchito - kuphatikiza kuyesa kwa hydrostatic pressure bar kwa ma valve 450
Timasunga kutsata kwathunthu - osati kuchuluka kwa kutentha kokha. Gawo lililonse limalumikizana ndi chipika chake chosungunula, kuchuluka kwa kuzungulira kwa kufa, mpweya wa ng'anjo O₂ powerenga panthawi ya annealing, ndi ID ya opareshoni. Ngati kasitomala anena za vuto muutumiki wakumunda, timakoka mapasa onse adijito mkati mwa mphindi 90: zoyikapo, zida zomangira zida, kuyeza kwamphamvu kwapamtunda, ngakhale kuwerengera chinyezi pamalo omaliza tsikulo.
- Zipangizo zopangira kuchokera ku mphero zotsimikizika kupita ku ASTM A957 / EN 1559-3
- Zonse za cobalt alloy castings zoyesedwa pa ASTM E125 pakuwunika kwa tinthu tating'ono
- Kutsata kwapang'onopang'ono kutsimikiziridwa motsutsana ndi ASME Y14.5-2018, osati "kusindikiza" kokha
- Palibe "chivomerezo cha nkhani yoyamba" popanda kuyesa kogwira ntchito-palibe kuchotserapo
Kusankha Bwenzi Loyenera Sizokhudza Kutha - Ndi Za Kuvuta Kwambiri
A mphamvu yokoka kufa kuponya mbali fakitale yokhala ndi matani a 200 / mwezi sikutanthauza pang'ono ngati singagwire ± 0.025 mm panyumba ya 300-mm cobalt alloy posunga dongosolo lambewu. Chofunikira ndi momwe gulu limamvetsetsa mozama chifukwa chake maziko anu a pampu amang'ambika pa nthawi yothamanga ya maola 12,000-kapena chifukwa chomwe valve yanu yamagetsi imatuluka pambuyo pa njinga yamoto.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imayang'ana kwambiri pamagulu anayi apamwamba kwambiri: zida zama hydraulic system, zida zamafuta & gasi, makina amagalimoto aumisiri, ndi misonkhano yapadera yamapampu. Sitiponyera mabokosi okongoletsera kapena nyumba zochepetsetsa. Timathetsa mavuto pomwe kulephera kuyimitsa mizere yopanga, kuyambitsa kuzimitsa chitetezo, kapena kuphwanya API 6A kapena ISO 15156 zofunika.
sitepe yathu yotsatira? Kuyika zowunikira zenizeni zenizeni m'mabowo - ndikulumikiza mbiri yotentha ndi mitundu yolosera yokonzekera zida zamakasitomala. Osati chifukwa ndi novel. Chifukwa imadula nthawi yosakonzekera ndi 22% pamayesero am'munda. Ndiwo mtundu wolondola womwe sumakhala m'kabuku. Iwo amakhala mu gawo.
