Mainjiniya akamatchula ma valve achitsulo chosapanga dzimbiri, sikuti amangoyitanitsa magawo - amateteza kukhulupirika kwa dongosolo pansi pa kupsinjika, kutentha, ndi dzimbiri. Kuwonongeka kumodzi kokha mu valavu yowongolera ma hydraulic kumatha kulowa mu nthawi yopumira, pachiwopsezo chachitetezo, kapena kulephera kwamunda. Ndicho chifukwa chake kufufuza kuchokera ku a zitsulo zosapanga dzimbiri valavu castings fakitale ndi kutsimikiziridwa zitsulo chilango - osati foundry mphamvu - sikungakambirane.
Umphumphu Wakuthupi Umayamba Usanathiridwe
Tawona mapulojekiti ambiri akuchedwa chifukwa cha kusagwirizana kwambewu mu 316 kapena F22 zosapanga dzimbiri. Si kawirikawiri za chemistry yokha. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mulu uliwonse wa zitsulo zosapanga dzimbiri umayamba ndi traceability ya zinthu zovomerezeka - mpaka pa chiwerengero cha kutentha ndi lipoti la mayeso a mphero. Palibe kuchotserapo. Opereka athu ali oyenerera kale kudzera mu kafukufuku wazitsulo, osati zolemba zokha. Timatsimikizira zomwe zili mu kaboni, milingo ya ferrite, komanso kukana kwa corrosion intergranular *kusungunuka kusanayambe. Kwa matupi othamanga kwambiri omwe amafunikira ASTM A351 CF8M kapena A743 CA15, kutsimikizira kumeneku kumalepheretsa kukhazikika kwa gawo la sigma muutumiki.
Izi sizongoyerekeza. Makasitomala m'modzi wa zida zamafuta aku North America adalowa m'malo mwa wopikisana naye atalephera katatu pama valve otulutsa pompo. Onse atatu adawonetsa micro-porosity pafupi ndi madera olowera-ndi kutsata ziro. Kuponyera kwathu m'malo kunadutsa kuyesa kwa hydrostatic pa 1.5 × rated pressure, yokhala ndi ma radiographic (RT) ndi ma dye penetrant (PT) omwe adasungidwa kwa zaka 10.
Kumene Kuponyera Kumakumana ndi Precision Machining
Zopangira zitsulo zosapanga dzimbiri sizimalephera poyambira - koma pamawonekedwe apakati pa kulolerana ndi geometry yogwira ntchito. Kukhuthala kwa khoma ± 1.5 mm kungawoneke kovomerezeka pamapepala. Koma makina omaliza akamachotsa 3 mm kuti agunde kukhazikika kwa mpando mkati mwa 0.005 mm, kupsinjika kotsalira kumasokoneza gawolo. Ichi ndichifukwa chake kuphatikiza koyima ndikofunikira.
QINGDAO QIANGSENYUAN imayendetsa ndalama ndikuponya mchenga *pambali* makina a CNC amitundu yambiri mu malo amodzi ogwirizana ndi ISO. Timayika ma valavu pamakina titangotha kuchepetsa kutentha kwapang'onopang'ono-osati milungu ingapo pambuyo potumiza kwa subcontractor. Izi zimayendetsa kupotoza. Timakhala ndi ma callout a GD&T ngati kulolerana kwa 0.02 mm kwa ma bore oyendetsa ndege okhudzana ndi nkhope za flange-ndizofunika kwambiri pakutseka kolimba. Ndipo timamaliza kusindikiza malo ndi galasi-wopukuta (Ra ≤ 0.2 µm), osati kungotembenuza.
- Mavavu thupi castings: ASTM A351 CF8, CF8M, CF3M; ASME B16.34 yogwirizana
- Mphete zapampando & mapulagi oyika: Zolimba 17-4PH kapena ma aloyi amtundu wa cobalt (AMS 5387)
- Nyumba zokhala ndi zopanikizika: Kufikira Class 2500, zovomerezeka pa API 598
- Zomaliza zapamwamba: Zopangidwa ndi magetsi, zodutsa, kapena zokongoletsedwa ndi ASTM A967
Palibe "Standard" Pamene Magwiridwe Sangakambirane
Ogula ena amaganiza kuti "zitsulo zosapanga dzimbiri zitsulo" zimatanthawuza kukula kwa alumali. Chowonadi ndi chokhwima. Valavu yowongolera ma winchi yam'madzi imafunikira duplex yosamva madzi a m'nyanja (UNS S32205) yokhala ndi njira zoyendera zamakina zofananira ndi data yeniyeni yoyeserera ya hydraulic. Nozzle ya AMS 5387 cobalt alloy ya pampu yamankhwala yotentha kwambiri imafuna kulolerana kwa mbiri ya 0.01 mm pama convergent-divergent contours - zosatheka popanda kutsimikizika kwamkati kwa CMM motsutsana ndi CAD.
Sitikusunga ma generic castings. Timamanga mayunitsi ogwirira ntchito: ma spools okhazikika omwe ali ndi zotchingira zophatikizika, ma silinda okhala ndi chiwongola dzanja chowonjezera chamafuta omwe amapangidwira pamapangidwe opangira, mapampu a piston pomwe kulumikizana kwa doko kumakhudza mphamvu ya volumetric ndi> 3%. Chojambula chilichonse chimawunikidwanso pakupanga - osati pamtengo wokha, komanso momwe gawolo limachitira pa 200 bar ndi 120 ° C.
Ichi ndichifukwa chake pempho lathu lodziwika bwino si "kutumiza mawu kwa ma PC 100." Ndi "Kodi mungatsimikizire zosungirako za GD&T musanagwiritse ntchito?" Timatero—kugwiritsa ntchito ma ZEISS CONTURA CMM ndi ma optical profilometer, osati ma caliper okha. Ngati chojambula chamakasitomala chikuwonetsa malo enieni pa 6 mm wobowola ndi nkhope ya 300 mm flange, timatsanzira mphamvu zokhometsa ndi kutentha koyambirira. Kenako timadula.
Kutumiza Mungathe Kukonzekera Pozungulira
Kudalirika sikungokhudza ubwino - ndi za kuneneratu. Kuponya mochedwa kumasokoneza mzere wonse wa msonkhano. Timagwiritsa ntchito mapulani ocheperako okhala ndi mawonekedwe a kanban, osati kupanga ma batch-ndi-queue. Nthawi yotsogolera ya prototype? Masiku a 21 kuchokera pakujambula kovomerezeka. Kupanga kwapakatikati (ma PC 50-500)? Masiku 35 - otsekedwa molembedwa, ndi zosintha za mlungu ndi mlungu kuphatikizapo malipoti a NDT ndi mapepala a cheke.
Timatumiza padziko lonse lapansi, koma pewani zodabwitsa zapanyanja. Kutumiza kulikonse kumaphatikizapo paketi yabwino yosindikizidwa: ziphaso zakuthupi, zipika za kutentha, malipoti oyendera, ndi zithunzi za zinthu zofunika kwambiri. Palibe zolemba zakale za PDF zokha. Makope akuthupi amayenda ndi katundu. Chifukwa nyumba ya valve ikafika ku Rotterdam kapena Houston, injiniya wolandirayo sayenera kutumiza imelo kuti apeze umboni.
Zopangira zitsulo zosapanga dzimbiri sizinthu zofunika. Ndi zisudzo zonyamula katundu. Ufulu zitsulo zosapanga dzimbiri valavu castings fakitale sichimangothira zitsulo - ili ndi physics ya ntchito yanu. Kuchokera pakusankhidwa kwa aloyi wosungunula mpaka kumapeto komaliza, kuchokera ku chitsimikizo cha GD&T kupita kumayendedwe otumizidwa, kulondola sikutha kugawika. Ichi ndichifukwa chake akatswiri opanga ma hydraulic system, mafuta & gasi, komanso kupanga mapampu apadera amabwerera-osati pamtengo wotsika kwambiri, koma chifukwa cha kukonzanso ziro, kusamveka bwino kwa ziro, ndi kungoyerekeza ziro.
