Zigawo zoponya zapamwamba sizimangokhalira kukakamizidwa - zimawathandiza. M'ma hydraulic manifolds, pampu zam'mphepete mwa nyanja, kapena makina opangira ma winchi olemetsa, cholakwika cha 0.05 mm kulolerana si "kupatuka kwakung'ono." Ndi pistons anagwidwa. Ndi kutopa msanga m'milomo ya aloyi ya cobalt yomwe imawululidwa ku 450 ° C panjinga yotentha. Ndi nthawi yotsika yosakonzekera yomwe imawononga $ 18,000 / ola m'malo opangira mafuta. Tawona onse atatu - mobwerezabwereza-panthawi yowunikira uinjiniya ndi North America OEMs ndi European Tier-1 ogulitsa. Chifukwa chake? Osati kalasi yakuthupi. Osati kupanga cholinga. Ndilo kusiyana pakati pa kuponyera ngati chinthu chamtengo wapatali - ndikuponyera ngati njira yogwirira ntchito yaukadaulo.
Kuponyera Molondola Kumayambira Komwe Mchenga Ukumana ndi Metallurgy
Ogula ambiri amatenga zida zoponyera zinthu ngati zopanda kanthu: "Iyikeni pafupi, kenako sungani zina zonse." Njira imeneyi imalephera pamene makulidwe a khoma amasiyanasiyana ± 1.2 mm kudutsa nyumba ya silinda ya 320 mm-kapena pamene kupanikizika kotsalira kuchokera ku kuzizira kosiyana kumawombera maziko a chitsulo chosapanga dzimbiri pambuyo pa kutentha kwa kutentha. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timasintha malingaliro amenewo. Kuponyedwa kulikonse kwachitsulo kumayamba ndi kulimbitsa kayesedwe. Chigawo chilichonse cha AMS 5387 cobalt alloy chimayang'ana mapu ambewu musanapangidwe. Chifukwa chiyani? Chifukwa kuchepa sikochitika mwachisawawa-ndizodziwikiratu. Ndipo kulosera kumatanthauza kuwongolera kukhulupirika kwa microstructure * pamaso* kutsanulira koyamba.
Ichi ndichifukwa chake nyumba zathu zapampu za pistoni zoponyera mchenga zimakwaniritsa Cpk ≥1.67 pamabowo ovuta-ngakhale opanda mpumulo wa post-cast. Ichi ndichifukwa chake mapulagi osakhazikika a T800 amakhalabe olimba (HRC 42–44) pamagulu 120 a mayunitsi. Palibe kukonzanso batch-to-batch. Palibe "malipiro osintha" pamakina omaliza. Makhalidwe obwerezabwereza azitsulo, otsimikiziridwa ndi kusanthula kowoneka bwino komanso kuyesa kwamphamvu pa ASTM E8/E23.
Pamene Machining Sangathe Kukonza Zomwe Kuponya Kwalakwika
Akatswiri ena amaganiza kuti CNC ikhoza kubweza zolakwika zomwe zachitika. Izo sizingakhoze-osati kwa mawonekedwe ovala apamwamba. Ganizirani chogudubuza chapakati cha shaft cha winchi yamagalimoto a engineering: gawo lapansi la 42CrMo4, OD yolimba, 0.8 µm Ra kumaliza. Ngati ID ya as-cast ili ndi magulu a porosity pafupi ndi mpando wonyamulira, makina amawulula voids. Kupera pamwamba kumapanga ming'alu yaying'ono. Gawoli limalephera pa 37% ya moyo wozungulira. Tidachita izi pakuwunika kulephera limodzi ndi womanga zida zamigodi ku Southeast Asia. Wowagulitsira m'mbuyomu adapereka "m'kati mwa kulolerana" - koma adaphonya porosity yomwe idayikidwa mu Appendix B ya ISO 4990 Class 2.
Chidziwitso chathu sichinali makina olimba. Iwo anali redesigning dongosolo riser, kusintha kwa ceramic TACHIMATA nkhungu, ndi kuwonjezera akupanga anayendera pa 100% ya zigawo zofunika. Zotsatira: ziro zolakwika zamkati m'magawo 1,240 otumizidwa. Kukwera mtengo? 6.3%. Kuchepetsa nthawi yopuma? 100% pa miyezi 18.
Magulu Anayi. One Non-Negotiable Standard.
Timayang'ana kwambiri mabanja a magawo anayi - chifukwa kuzama kumadutsa m'magawo ofunikira kwambiri:
- Kuponyedwa kwachitsulo: ASTM A48 Grade 30B nyumba zokhala ndi ma valve othamanga kwambiri-zoyesedwa ku 1.5 × ntchito yogwira ntchito ndi zero leakage
- Chitsulo & zitsulo zosapanga dzimbiri: AISI 316L pampu maziko okhala ndi delta ferrite yoyendetsedwa (3-8%) ya kukhulupirika kwa weld
- Cobalt-nickel alloy zigawo: AMS 5387 nozzles ovomerezeka pa ASTM F3062 kukana kukokoloka kwa abrasive slurry service
- Zithunzi za CNC-makina: Zigawo zophatikizika ngati nyumba za silinda pomwe zida zopangira ndalama zimapangitsa kuti mizere yamkati ikhale yosatheka ndi mchenga wokha
Gulu lililonse limagawana protocol imodzi: kutsatira kwathunthu. Nambala iliyonse yotentha imalumikizana ndi ma certs, mitengo yothira, malipoti a NDT, ndi data yomaliza ya CMM. Palibe "chidule cha batch." Palibe "chitsanzo choyimira." Ngati gawo lanu likulephera, mumapeza mbiri yeniyeni-osati kumanganso.
Kudalirika Sikuperekedwa. Zimapangidwa - Kenako Zatsimikiziridwa.
“Wopereka Certified” amatanthauza zochepa ngati kuyendera kumachitika pa risiti pazipata komanso kutumiza komaliza. Timayika kuwongolera kwaubwino pazigawo zitatu zosakambitsirana: kutsimikizira kwazinthu zomwe zikubwera (OES + PMI), macheke amkati pogwiritsa ntchito ma Zeiss CONTURA G2 CMM okhala ndi machitidwe a GD&T, komanso kutsimikizika kogwira ntchito-monga matupi oyesa kukakamiza ma valve pa bar 220 kwa mphindi 30 ndikuzindikira kutayikira kwa helium mpaka 1 × ⁶ kudziwika kwa helium mpaka 1 × ⁶
Izi sizowonjezera-injiniya. Ndi kuchepetsa chiopsezo. Pamene wogawa ma hydraulic ku Europe amafunikira chithandizo cha 24/7 kuti alowe m'malo mwachangu, kayendedwe kathu kowonda komanso kukonzekera kokonzekera kamangidwe kumadula nthawi yotumiza kuyambira masabata 14 mpaka 8.6-ndi ziro zololedwa pamalire a AMS 2269 kapena ASTM E165 zofunika kulowa mkati mwamadzi.
Zida zoponyera zapamwamba kwambiri zimathetsa mavuto enieni: dzimbiri m'madera akunyanja, kugwedezeka kwamafuta m'mapampu a geothermal, kuvala kopangidwa ndi tinthu m'makina a simenti. Palibe kudzaza bilu yazinthu. Iwo alipo kuti asunge machitidwe akuyenda-pamene kulephera sikungatheke. Izi zimayamba ndikusamalira kuponyera osati ngati sitepe yopanga, koma ngati maziko a kudalirika komweko. Pazinthu zofunikila zamafakitale, kusiyanitsa kumeneko siukadaulo. Zimagwira ntchito.
