Pamene mainjiniya amatchula a valavu mphete fakitale, sikuti akungopeza gawo chabe - akusankha mnzake wokhoza kupirira ± 0.005 mm pansi pa 350 bar hydraulic loads, kukana kuphulika pamipando ya mipando ya cobalt-alloy, ndikupereka microstructure yobwerezabwereza pamagulu a zidutswa 500. Ndicho chenicheni chogwirira ntchito kumbuyo kwa njira iliyonse yowongolerera yothamanga kwambiri pamapampu akunyanja, ma hydraulics amigodi, kapena magawo othandizira ndege.
Tawona magulu ambiri ogula zinthu akuchedwa mapulojekiti chifukwa mphete za valve zinafika ndi mbiri yosagwirizana-42-48 HRC m'malo mwa 45 ± 2 HRC yofunikira-kapena ndi kusiyana komaliza komwe kunachititsa kuti chisindikizo chisakwane. Izi si "zopatuka zazing'ono." Amayambitsa kulephera kwa magwiridwe antchito m'makina omwe amatumizidwa m'malo momwe kusinthira kumatanthawuza nthawi ya crane, nthawi yopumira, komanso chiwopsezo chachitetezo. Chifukwa chake? Unyolo wogawikana: kuponyedwa mu shopu imodzi, chithandizo cha kutentha chimaperekedwa kwa china, kugaya komaliza kumayendetsedwa ndi gawo limodzi mwa magawo atatu - popanda gulu limodzi lomwe limayankha kupitiliza kwazitsulo kapena kutsata kwa GD&T.
Ichi ndichifukwa chake mapulogalamu olondola-ofunikira kwambiri amatembenukira kwa opanga ophatikizika ngati QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Malo awo a Qingdao samangopanga mphete za ma valve - amawongolera unyolo wonse: chiphaso cha AMS 5387 cobalt alloy ingot, kuyika ndalama ndi mitengo yolimba yolimba, kuchepetsa nkhawa CNC isanatembenuke, ndikutsimikizira komaliza kwa CMM motsutsana ndi ma data ogwirizana ndi ASME Y14.5. Mphete iliyonse imakhala ndi kutsatiridwa kwazinthu zonse - kuchokera pa nambala ya kutentha mpaka lipoti la kuyesa kwamphamvu - ndipo gulu lililonse limakumana ndi zitsanzo zowononga pa ASTM E8/E290 ikatchulidwa. Izi sizowonjezera-injiniya. Ndimomwe mumapewa kumangidwanso kwa $ 220,000 pambuyo pa maola 800 ogwirira ntchito.
- Kukhoza kwakuthupi kumafunika: Mphete za vavu zimalephera nthawi zambiri chifukwa cha dzimbiri kapena kutopa chifukwa cha kutentha—osati kugwedezeka kwa dimensional. Ntchito yotsimikiziridwa ya QIANGSENYUAN yokhala ndi T800 cobalt-based alloys imaphatikizanso kukhathamiritsa njira zothetsera kutsekereza mapangidwe a sigma m'malo otentha. Ife tatsimikizira mphete zawo mu 150 ° C glycol malupu ndi ziro pitting pambuyo 12 miyezi.
- Geometry imatanthawuza ntchito: Kupatuka kwa mamilimita 0.02 mu ngodya ya chamfer pa mphete yolumikizira kukakamiza kumasuntha kugawa katundu ndi 17% -kupimidwa ndi mapu azovuta panyumba zoyeserera. Malo awo opangira makina ambiri amakhala ndi malo enieni mkati mwa 0.008 mm pazinthu monga malo osindikizira ma radial ndi ma axial vent grooves.
- Kukhulupirika kwapamwamba sikungakambirane: Ra 0.4 µm si "yosalala mokwanira." Electropolishing yawo ya post-machining imachotsa misozi yaying'ono yosiyidwa ndi zida za carbide-zofunikira kwambiri poletsa malo oyambira kutopa kwambiri. Makasitomala akuwonetsa moyo wautumiki wa 3.2 × wautali poyerekeza ndi mphete zanthawi zonse pakubweza kwa mpope.
Ena angatsutse kuti kuponyera + makina kumawonjezera mtengo poyerekeza ndi kupanga kosavuta. Koma taganizirani izi: mphete zopukutira zimafuna mafelemu okwera mtengo kwambiri, nthawi yayitali yosinthira zida, komanso kusinthasintha kwa geometry. Pamene kasitomala amafunikira mpando wosakhazikika wa 32 ° wokhala ndi njira zoziziritsa zophatikizika za valve yothamanga kwambiri ya subsea, QIANGSENYUAN idapereka ma prototypes ogwira ntchito m'masiku a 11 pogwiritsa ntchito kuponyera ndalama + 5-axis milling-palibe ndalama zakufa, palibe kunyengerera pakuwongolera makulidwe a khoma. Ndalama zonse zomwe adafika zinali zotsika ndi 14% kuposa njira ina yopangira, ndi ziro zotsalira popanga koyamba.
Zomwe zimasiyanitsa munthu wodalirika valavu mphete fakitale kuchokera kwa ogulitsa zinthu sizimalemba manambala kapena ma MOQ. Kuthekera kolembedwa: CpK ≥1.67 pama diameter ovuta, optical profilometry yotsimikizika yotsimikizira m'mphepete mwa radius, komanso kuyang'anira nthawi yeniyeni ya kutentha panthawi ya chithandizo cha kutentha. Ili ndi mainjiniya oyimba yemwe adawunikanso ma valve 47 a ma hydraulic valve - osati kungowerenga pepala. Ndikudziwa momwe mphete ya mphete yanu imayendera imagwirizana ndi ma vectors opsinjika, osayembekeza kuti zitero.
Mphamvu ya QINGDAO QIANGSENYUAN TECHNOLOGY ili pamlingo wokhazikika. Samapanga zomangira, mabulaketi, kapena nyumba zamagetsi zamagetsi. Mapaipi awo onse a R&D amadyetsedwa m'magulu anayi: zida zamakina za CNC, zida za aloyi za cobalt-nickel, zitsulo zoponyera chitsulo, ndi zitsulo zosapanga dzimbiri - zonse zokongoletsedwa kuti zizigwira ntchito pamakina othamanga kwambiri, ovala kwambiri. Ntchito yanu ikafuna ma nozzles a AMS 5387, mapulagi a T800, kapena nyumba za silinda zapampu ya piston, ukatswiri wokhudzana ndi domain sizosankha. Ndiko kusiyana pakati pa kukonza kokonzekera ndi kulephera koopsa.
Kuyang'ana m'tsogolo, makampani akusintha njira zopangira makina osakanizidwa - pomwe mawonekedwe apafupi amachepetsa zinyalala zakuthupi ndi 38% ndikusunga mbewu zolunjika - zidzakomera opanga omwe ali ndi luso lophatikizika. Ndalama zomwe QIANGSENYUAN zikupitilira pakusungunuka kwa vacuum induction melting ndi in-process metrology zimawapangitsa kuti akwaniritse ziyembekezo zokulirapo zamagawo amafuta & gasi ndi zam'madzi. Ngati ndondomeko yanu ya mphete ya valve ikuphatikizapo zofunikira za NACE MR0175 kutsata, kutsimikizira kwa PMI, kapena kugwirizanitsa kwa weld-overlay, yambani ndi wopanga yemwe amagwiritsa ntchito zitsulo monga engineering-osati katundu.
