Zida zachitsulo zosapanga dzimbiri sizimangolimbana ndi dzimbiri - zimasunga kupanikizika, zimapulumuka ku abrasion, ndikukhalabe okhazikika pamene kulephera sikungatheke. M'ma hydraulic manifolds omwe adavotera mipiringidzo 350, m'zinyumba zopopera zozungulira 3,600 RPM pansi pa slurry, kapena m'mphepete mwa mitsinje yamphepete mwa nyanja yomwe ili ndi mphepo yodzaza ndi mchere komanso ma cyclic torque - mbali izi "si zabwino kukhala nazo." Iwo ndi anangula ofunikira kwambiri. Tawonapo mavavu akuphwanyidwa chifukwa cha kuwonongeka kwa chloride-induced stress corrosion mu zomera za Southeast Asia desalination. Tasinthanso nyumba za silinda zomwe zidasokonekera pambuyo pa miyezi 18 yakuyenda panjinga zotentha m'mapampu amafuta aku North America. Kulephera kulikonse kunatiphunzitsa chinthu chimodzi: chitsulo chosapanga dzimbiri sichinthu chosankha - ndi chisankho chadongosolo.
Chifukwa Chake Zida Zachitsulo Zosapanga dzimbiri Zimaposa Njira Zina mu Real-World Service
Aluminiyamu amawononga msanga m'madzi a chlorini. Chitsulo cha kaboni chimafunika kupenta mosalekeza-ndipo zimalephera kwambiri ngati zokutira zitadulidwa. Zitsulo zosapanga dzimbiri za Duplex ngati UNS S32205 zimapereka mphamvu zochulukirapo kuposa 450 MPa pomwe zimakana kuponyedwa m'madzi a m'nyanja. Koma mphamvu yokhayo sikutsimikizira kuti ntchitoyo ikugwira ntchito. Timayesa gulu lililonse lazitsulo zosapanga dzimbiri 316 za ferrite (chandamale: 4-7%); Pang'ono ndi pang'ono imayitanitsa kusweka kotentha panthawi yowotcherera, kuchulukitsa kumachepetsa kulimba. Ichi ndichifukwa chake makasitomala athu pamagalimoto aku Europe opanga ma OEM amatchula ASTM A995 Grade CD4MCu-osati chifukwa "ndi chosapanga dzimbiri," koma chifukwa mawonekedwe ake amitundu iwiri amapulumuka kuchulukidwa mobwerezabwereza m'ma roller okwera popanda kufalitsa ma microcrack.
Kukana kwa corrosion sikungopeka. Imayezedwa m'maola amchere-kupopera mchere (ASTM B117), kutsimikiziridwa ndi kuyerekezera kwa magawo a SEM a makulidwe a filimu yokhazikika, ndikutsimikiziridwa mu ntchito yeniyeni yamadzimadzi. Pamene wopanga mpope wa ku United States anasintha kuchoka pa 304 kupita ku 316 zitsulo zosapanga dzimbiri pa mizere yotumizira mankhwala, nthawi yopuma idatsika ndi 62% -osati kuchokera ku makina abwino, koma kuchotsa chloride-assisted crevice corrosion pa flange interfaces. Kusiyana sikunali kalasi ya alloy yokha. Imayendetsedwa ndi chithandizo cha kutentha (kuwongolera annealing pa 1040-1120 ° C, kuzimitsidwa mwachangu), kuwongolera mwamphamvu pamwamba (Ra ≤ 0.8 µm pamalo osindikizira), komanso kutsata kwathunthu kubwerera kumadzi osungunuka.
Kumene Magawo Amtundu Wanthawi Zonse Amafupikitsa-ndi Zomwe Injiniya Amafunikiradi
Ena angatsutse kuti zida zachitsulo zosapanga dzimbiri zosapanga dzimbiri zimapulumutsa nthawi komanso mtengo. Koma kutumizidwa kwadziko lenileni kumapereka nkhani ina. Wogawira ma valve a hydraulic valve ku Germany adatulutsapo matupi a generic 316L pamayendedwe oyendetsa othamanga kwambiri - kungozindikira kusagwirizana kwamkati pambuyo poyesa kukakamiza pa bar 420. Kutayikira sikunawonekere pazisindikizo, koma kudzera m'malo apansi panthaka pafupi ndi zipata. Kukonzekera kwawo? Kupanganso makina opangira mageti ndikusintha kuzinthu zopangira ndalama ndikuwunika kwa X-ray pa ASTM E94. Izo sizowonjezera-injiniya. Ndiyo physics.
Nthawi zonse timakumana ndi zofunikira zitatu zomwe injiniya sizingakambirane m'mabuku:
- Kukhazikika kwapang'onopang'ono pamatenthedwe: Nyumba za Cylinder ziyenera kukhala ndi ± 0.015 mm kulolerana pakati pa -20 ° C ndi +120 ° C - zomwe zimatheka kudzera muzitsulo zochepetsera nkhawa pambuyo popanga makina ovuta, ndiyeno CNC yomaliza imatsirizidwa pa kutentha kokhazikika.
- Microstructure umphumphu pa kupsinjika maganizo: Kusintha kowoneka bwino pamapampu a pisitoni kumafunikira kuwomberedwa pambuyo pa makina kuti kupangitse kupsinjika kotsalira pamwamba-kutsimikiziridwa kumatalikitsa moyo wotopa ndi 3.2 × pakuyezetsa moyo mwachangu.
- Ubwino wogwirira ntchito kupitilira Ra: Malo osindikizira amafunikira kuchuluka kwapamwamba (Pc> 200/mm) ndi chiŵerengero cha mapiri (Rpk <0.2 µm)—osati kukhakhakhakha—kuonetsetsa kuti chisindikizo cha elastomer chikugwirizana ndi katundu wosinthasintha.
Chilango Chopanga Zinthu Ndi Chidziwitso Chosawoneka
Mutha kufotokozera zitsulo zosapanga dzimbiri 316-koma popanda kuwongolera, mumapeza magwiridwe antchito. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Chigawo chilichonse chachitsulo chosapanga dzimbiri chimadutsa poyang'ana malo asanu ovomerezeka: chitsimikiziro chazinthu zopangira (malipoti oyesa mphero ndi traceability nambala ya kutentha), kutsimikizira kwa CMM pazidamu zovuta za GD&T, zitsanzo zazitsulo pa ASTM E3, kukakamiza kogwira ntchito kwa ASTM E3, zero × 5. kuyendera pansi pa 10 × kukulitsa kwa discontinuities pamwamba. Palibe zombo zamagulu zopanda zolemba zonse - kuphatikiza kulimba kwamapu pamagawo am'mbali mwazojambula.
Chilangochi chimakhala chofunikira kwambiri komwe miyezo imathera ndikugwiritsa ntchito. Mphuno ya aloyi ya cobalt (AMS 5387) imatha kugawanika ndi chitsulo chosapanga dzimbiri - koma makina ake amafunikira njira zapadera, zoziziritsa kukhosi za cryogenic, ndi zida zonyowa. Tawonapo masitolo akuyesa mphero zozikidwa pa T800 pa ma VMC wamba, zomwe zimapangitsa kuti zida ziwonongeke msanga komanso kuphulika kwapamunsi. Yankho lathu? Malo odzipatulira okhala ndi torque yayikulu, otsika-RPM okhala ndi kuyang'anira katundu wa spindle munthawi yeniyeni ndikuwongolera chakudya chosinthika. Mbaliyi imawoneka yofanana pa zolembedwa - koma kutopa kwake kumasiyana malinga ndi kukula kwake.
Kusankha Bwenzi Loyenera Kumatanthauza Kufunsa Mafunso Oyenera
Funsani omwe akukugulirani: Kodi amatsimikizira porosity kudzera m'mafakitale CT-osati kungolowetsa utoto? Kodi atha kukhala ndi malo enieni a ± 0.005 mm pa Ø12 mamilimita otalikirana ndi 320 mm mumchenga wochuluka? Kodi amasunga ma cert kwa zaka 10-kapena mpaka kutumizidwa? Izi si "zabwino-kudziwa." Ndiwo kusiyana pakati pa gawo lomwe limatenga maola ogwirira ntchito 5,000 ndi lomwe limalephera pa 800.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga zitsulo zosapanga dzimbiri m'malo omwe kusagwirizana kumatanthauza kutseka, kuwopsa kwachitetezo, kapena kusatsata malamulo. Malo awo ogwirizana ndi ISO amayang'anira chilichonse kuyambira pakupanga ndalama zofananira mpaka kupanga ma CNC apakati-ndi mayankho athunthu apangidwe asanadule chitsulo choyamba. Sagulitsa magawo. Amathetsa njira zolephera zogwirira ntchito - zisanachitike.
Chifukwa m'mafakitale, kulimba sikumayesedwa muzaka. Zimayesedwa mu nthawi yosasokonezeka, kusinthasintha kwa kayendedwe kake, ndi zochitika zosakonzekera zosakonzekera. Izi ndi zomwe zigawo zazitsulo zosapanga dzimbiri zimapereka - zikapangidwa, osati zongotchulidwa.
