Pamene mainjiniya amatchula a zitsulo zosapanga dzimbiri valavu fakitale, sikuti amangoyitanitsa magawo - akusankha bwenzi lomwe lingathe kupirira ± 0.01 mm pansi pa kukakamizidwa kwa bar 350, kukana kuponyera kwa kloridi pamapampu akunyanja, ndikupereka umphumphu wobwerezabwereza wa microstructure pamagulu 500-mayunitsi. Ndicho chenicheni cha ntchito-osati chinenero cha malonda.
Tawona mapulojekiti ambiri akuyimitsidwa pamlingo wofananira chifukwa wogula omwe adasankhidwa adagwiritsa ntchito mavavu azitsulo zosapanga dzimbiri ngati ma generic casting m'malo mwa zida zofunika kwambiri zowongolera kuyenda. Pa QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., valavu iliyonse imayamba ndi cholinga chazitsulo: kalasi yazinthu (CF8M, F51 duplex, kapena mwambo ASTM A995 Gr. 4A), kutentha kwa mankhwala (njira yothetsera anneal + kuzimitsa mbiri yotsimikiziridwa pa ASTM A995), ndi kutsiriza pamwamba pa 0m. Palibe zongoganizira. Palibe njira zazifupi za "standard".
Zosankha zitatu zaukadaulo zimasiyanitsa kupanga odalirika kwa OEM ndi kupanga zinthu - ndipo zonsezi zimachitika makina asanayambe.
- Kufufuza kwazinthu sikosankha - kumaphatikizidwa. Kutentha kulikonse kumakhala ndi malipoti athunthu a mayeso a mphero (MTRs) ovomerezeka ku EN 10204 3.1, yokhala ndi mankhwala ovomerezeka motsutsana ndi ASTM A351 komanso makina amakina omwe amatsimikiziridwa kudzera pakuyesa kwamphamvu pamakuponi enieni opanga - osati mipiringidzo yokha.
- Njira yothetsera vutoli imagwira ntchito. Kuponyera mchenga kumagwira ma valve akuluakulu a thupi mpaka 120 kg ndi mitengo yolimba yoyendetsedwa; kuponya ndalama kumapereka matupi opyapyala, olondola kwambiri a mavavu oyendetsa siteji pomwe makulidwe a khoma ayenera kukhala mkati mwa ± 0.3 mm. Sitikakamiza kuti tigwirizane ndi ma geometries onse.
- GD&T sichiwunikiridwa pambuyo polemba mawu - imathetsedwa pakutsimikizika kwa uinjiniya. Makasitomala akatumiza chojambula chomwe chikuyitanitsa kulekerera kwa Ø0.05 mm pampando wa vavu wolingana ndi nkhope ya flange, gulu lathu limayang'ana ngati gululo likugwirizana ndi kuthekera kokhazikitsira -ndipo kuwonetsa mikangano *zida zisanayambe. Mwezi watha, izi zidasokonekera pakati pa zofunikira za gulu la ASME B16.34 ndi kuuma kwapamtunda kwa thupi la valve 4-inch.
Ena atha kunena kuti ogulitsa akunyanja sangafanane ndi kusasinthika kochokera ku Europe. Koma tatumiza ma valve 27 motsatizanatsatizana a AMS 5387 cobalt-alloy pressure relief valves kupita ku Tier-1 hydraulic systems integrator ku Germany-ndi zero dimensional rework and full batch traceability back to raw billet heat numbers. Kusiyana kwake? Kuphatikiza koyima. Timayang'anira kuponyera, makina a CNC (5-axis for complex port geometries), njira yothetsera kutentha, ndi kuwotcha komaliza - zonse pansi pa denga limodzi lovomerezeka la ISO 9001. Palibe ma handoffs. Palibe mipata ya mawonekedwe. Palibe kudzudzula "nyumba yoponyera" pomwe malo opangidwa ndi makina amalephera kuyesa kwa hydrostatic.
Izi sizongoyerekeza. Mu projekiti ina yaposachedwa, fakitale yaku Southeast Asia yochotsa mchere m'madzi idafunikira ma valve olowa m'malo kuti igwiritse ntchito mchere wambiri. Wowagulitsira m'mbuyomu adagwiritsa ntchito CF8M yokhazikika, kenaka adawonjezera kutsitsa pambuyo pa weld. Tidatchula F53 duplex chitsulo chosapanga dzimbiri, kukhathamiritsa njira yolowera kuti kuchepetsa kutsika kwapakati munyumba ya diski, ndikuchita ASTM A967 nitric acid passivation * pambuyo * kukonza komaliza koma * isanachitike * msonkhano. Zotsatira: 42% moyo wautali wautumiki pakuyesedwa kofulumira kwa dzimbiri. Deta yeniyeni—osati zongoyerekeza.
Kodi mawu akuti "custom solutions" amatanthauza chiyani m'sitolo?
- Valavu yosavomerezeka ya 3-way diverter grooves yophatikizira yowonjezera kutentha - yopangidwa kuchokera ku T800 cobalt-based alloy pogwiritsa ntchito zida za carbide zokhala ndi zoziziritsa kukhosi komanso kuyang'anira kugwedezeka kwanthawi yeniyeni.
- Nyumba ya silinda ya pampu ya pisitoni yomwe imafuna kutsimikizika kwa kuuma kwapakati pazigawo zitatu zakuya (pamwamba, pakatikati pa khoma, pakati) pa ASTM E140, zotulukapo zimayikidwa pa nambala iliyonse ya seriyo.
- Winch center shaft roller yokhala ndi misewu yolimba (HRC 58-62) ndi OD concentricity yosungidwa mpaka 0.008 mm TIR - yotsimikiziridwa pa Zeiss Contura G2 CMM yowerengedwa tsiku lililonse.
Palibe ma valve awiri omwe amagwira ntchito mofanana-ngakhale miyeso ikuwoneka mofanana pamapepala. Vavu yowongolera mutu wamafuta ndi gasi imafuna kulimba kosiyanasiyana pa -46 ° C kuposa imodzi yaukhondo wamagulu azakudya pa 121 ° C mikombero yotseketsa nthunzi. Timatsimikizira zonse ziwiri pogwiritsa ntchito njira zoyeserera -osati mndandanda wotsatira.
Ngati mukuyesa a zitsulo zosapanga dzimbiri valavu fakitale, funsani mafunso atatu musanasaine PO:
- Kodi mungandiwonetseko ma MTR ndi zolemba zochizira kutentha kwa mavavu atatu omaliza a CF8M?
- Kodi mumatsimikizira bwanji kufanana kwa mavavu amtundu wa 150-mm-makamaka pafupi ndi zokwera ndi zodyetsa?
- Kuyitanira kwa GD&T kukasemphana ndi kupangidwa, kodi mumapereka njira zina - kapena kungolemba mawu oti "momwe mwakokera"?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amayankha amene ali ndi umboni wolembedwa—osati malonjezo. Malo athu ku Qingdao amayendetsa ma cell 24/7 olondola molunjika limodzi ndi mchenga ndi mizere yopangira ndalama, zonse zimadyetsedwa m'dongosolo limodzi loyang'anira momwe malo aliwonse oyendera amajambulidwa ndi digito munthawi yeniyeni. Sitimagulitsa mavavu. Timapereka magwiridwe antchito otsimikizika-otheka kutsatiridwa, obwerezabwereza, komanso opangidwa ndi katundu wonyamula, osati ndandanda.
Tsogolo liri la opanga omwe amachitira zitsulo zosapanga dzimbiri osati gulu lazinthu-koma monga dongosolo: chemistry, gawo la gawo, kapangidwe ka tirigu, umphumphu wa pamwamba, ndi geometry yogwira ntchito, zonse zogwirizana ndi malo ogwirira ntchito. Umu ndi momwe kudalirika kumapangidwira - osayang'aniridwa.
