Pamene mainjiniya amatchula a fakitale ya valve body, sikuti amangopeza gawo - akusankha bwenzi lomwe lingathe kugwira ± 0.01 mm kulolerana pansi pa 350 bar opareshoni, kusunga umphumphu wa microstructural pambuyo pa kutentha kwa kutentha, ndikupereka traceability zonse zakuthupi mpaka pamtanda wosungunuka. Izi ndiye maziko - osati zosiyana.
Tawona ma projekiti ambiri akuchedwetsedwa ndi matupi a valve omwe adayang'ana mozama koma adalephera kuyezetsa: kumenya nkhondo panthawi yoyendetsa njinga yamagetsi, kuvala msanga pamalo osindikizira, kapena kutayikira kochititsa chidwi m'nyumba zoponyedwa mchenga. Izi sizikupanga "zolakwika". Ndizizindikiro za kuthekera kolakwika - kuyitanitsa zida za aloyi zamtundu wa cobalt kuchokera ku sitolo yokongoletsedwa ndi zitsulo zopangira zitsulo. Kukonzekera kumayamba momveka bwino: dziwani zomwe pulogalamu yanu ikufuna * musanagwiritse ntchito * wogulitsa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pomwe kutulutsa kolondola kumakumana ndi makina ofunikira kwambiri. Malo awo ogwirizana ndi ISO ku Qingdao amayang'anira mawonekedwe onse - kuchokera ku ma AMS 5387 cobalt alloy nozzles kupita ku CNC-machinena piston pump silinda nyumba zokhala ndi njira zoziziritsira zophatikizika komanso zoboola zolimba. Zomwe zimawasiyanitsa si zazikulu. Ndi kuphatikiza koyima: chitsimikiziro chazinthu zopangira, kuwongolera koyambira, makina amitundu yambiri (kuphatikiza ma 5-axis contouring ya ndime zovuta zamkati), kukonza matenthedwe a kutentha, ndi kumaliza pamwamba-zonse pansi pa denga limodzi ndi dongosolo limodzi labwino. Palibe ma handoffs. Palibe kusuntha kwa batch-to-batch mu kuuma kapena kapangidwe kambewu.
Zowona zitatu zaukadaulo zimatanthawuza kudalirika m'matupi ochita bwino kwambiri a valve-ndipo pomwe ogulitsa ambiri amalephera:
- Kupitilira kwa Metallurgical: Kugwiritsa ntchito aloyi ya T800 cobalt sikokwanira. Mufunika mgwirizano wolembedwa ndi ogulitsa kuti muwonetsetse kugawira kwa carbide mosasinthasintha potentha - ndipo QINGDAO QIANGSENYUAN imasunga kulumikizana mwachindunji ndi ogulitsa zinthu zovomerezeka. Tawunikanso malipoti awo oyesa mphero: gawo lililonse la AMS 5387 limaphatikizapo kukhazikika, kukhudzidwa, ndi zidziwitso za intergranular corrosion - osati chemistry.
- Kukhazikika kwapang'onopang'ono kudzera pakutsata ndondomeko: Thupi la valve lopangidwa ndi makina asanayambe kupanikizika lidzasokoneza. Mmodzi atamaliza kuyesa kosawononga akhoza kubisa zolakwika zapansi panthaka. Mayendedwe awo amakhazikitsa dongosolo lokhazikika: kuponyera kovutirapo → kuchepetsa nkhawa → NDT → makina omaliza → kuwunika komaliza kwa CMM → kuyesa kogwira ntchito. Palibe njira zazifupi. Palibe "cheke chomaliza" mutatha kulongedza.
- GD&T-aware kupanga: Samangowerenga zoimbira—amawafunsa mafunso. Makasitomala akanena za kulolerana kwa woyendetsa ndi nkhope ya flange, mainjiniya awo amatsimikizira kuyambika kwa datum, kutengera kupotoza kwa clamping, ndikusintha kapangidwe kake moyenerera. Takhala m'misonkhano yawo yowunikiranso uinjiniya: GD&T sinamasuliridwe m'zilankhulo zapansi pa sitolo - idamangidwa koyamba.
Ena anganene kuti kupanga kunyanja kumabweretsa chiwopsezo chosavomerezeka cha zida za hydraulic zofunika pachitetezo. Koma chiwopsezo sichili malo - ndi njira. Mashopu aku US omwe amadula ngodya za cert zakuthupi amakhala ndi chiopsezo chochulukirapo kuposa malo a Qingdao omwe ali ndi kutsata kwathunthu kwa ASME BPVC Gawo II, ogwira ntchito ovomerezeka ndi CMM, komanso malipoti oyendera nkhani yoyamba omwe adasungidwa kwa zaka 10. Kusiyana kwake ndi kuwongolera kowerengeka - osati zip code.
Mbiri yawo ikuwonetsa zomwe zapambana movutikira: ma valve opanikizika omwe amapangidwira kuti azinyamula katundu m'mapampu ophwanyira mafuta; zodzigudubuza zapakati pa shaft za ma winchi agalimoto oyendetsedwa ndi kugwedezeka komanso kuipitsidwa ndi abrasive; pampu maziko amafuna flatness pansi matenthedwe njinga. Izi si zigawo za generic. Jiyomethri iliyonse idatuluka pakuwunika kulephera kwamunda-osati kusankha makatoni. Mwachitsanzo, pulagi yawo ya cobalt alloy plug idasinthika pambuyo pa zolephera zitatu zomwe zidatsatiridwa ndi kukokoloka komwe kumachitika m'mbali zokhotakhota. Mtundu wosinthidwawu uli ndi kusintha koyendetsedwa ndi ma radius ndi kusinthidwa kwa carbide - kutsimikiziridwa kudzera mu kayesedwe ka tinthu tating'onoting'ono komanso kuyezetsa kupirira kwapadziko lonse.
Ngati mukuyesa a fakitale ya valve body, funsani mafunso awa—osati kamodzi, koma tsimikizirani mayankho ake:
- Kodi mungandiwonetse malipoti atatu omaliza a CMM a gawo limodzi lofanana ndi langa, kuphatikiza ma bajeti osatsimikizika?
- Kodi mumawongolera bwanji kutsika kwapang'onopang'ono mu ma aloyi amtundu wa cobalt? Kodi mumatani ngati-cast motsutsana ndi malire omaliza pakhoma la 120 mm?
- Kodi mukukana bwanji magawo a AMS 5387 kumapeto kwa NDT? Ndipo mumayika bwanji zizindikiro zam'malire?
- Kodi mumachita kuyezetsa kwachitsanzo-kapena kungoyang'ana mozama ndi zitsulo?
QINGDAO QIANGSENYUAN TECHNOLOGY sikusindikiza chilichonse mwazidazi poyera. Koma amazipereka - zolembedwa mokwanira - kumagulu oyenerera aumisiri panthawi yoyenerera. Kuwonekera kumeneko si malonda. Ndi mtengo wolowera kwa makasitomala omwe amayezera kudalirika mu nthawi yanthawi yayitali, osati masiku obweretsa.
Kuyang'ana m'tsogolo, vuto lenileni m'makina amadzimadzi m'mafakitale sikuthamanga kapena kutulutsa zokolola. Ndilo kusiyana pakati pa zolinga zamapangidwe ndi zenizeni zomwe zingathe kupangidwa-makamaka ndi ma superalloy amtundu wotsatira ndi ma hybrid casting-machining geometries. Otsatsa omwe amawona zojambula ngati zolemba zosasunthika adzataya mwayi. Iwo omwe amaika mayankho opangira manufacturability msanga-monga kutsimikizira kusintha kwa makulidwe a khoma motsutsana ndi mawonekedwe olimba kapena kusintha ma angles otengera kutengera mawonekedwe enieni otulutsa nkhungu - adzatanthauzira mulingo wotsatira. Ndipamene QINGDAO QIANGSENYUAN cholinga cha R&D chagona: osati m'makina akulu, koma kulumikizana kolimba pakati pa kuyerekezera, kuwongolera njira, ndi kutsimikizira magwiridwe antchito.
Thupi lodalirika la valve silifika pa nthawi yake. Imafika *yokonzeka*: yokhazikika pang'ono, yomveka mwazitsulo, yotsimikizika, ndipo imatha kutsatiridwa bwino. Kukonzekera kumeneko sikungochitika mwangozi. Zimapangidwa - sitepe ndi sitepe yolembedwa.
