Pamene dongosolo la hydraulic likulephera pansi pa kupanikizika kwakukulu, wolakwayo nthawi zambiri sakhala mpope kapena galimoto-nthawi zambiri ndi valve yowunika. Ndipo valavuyo ikatha masiku ambiri m'malo mwa zaka, akatswiri amapeza vutolo ku chinthu chimodzi: kusalimba mokwanira. Ichi ndichifukwa chake ma aloyi a Stellite opangidwa ndi cobalt, makamaka magiredi a AMS 5387 ndi T800, akhala osakambitsirana ndi ma valve oyendera mafakitale omwe amagwira madzi abrasive, njinga zamatenthedwe, kapena kupsyinjika kosalekeza. Koma kufufuza kodalirika fufuzani valavu Stetellite fakitale zibwenzi si za kupeza maziko aliwonse ndi ng'anjo. Ndizokhudza kuzindikira malo omwe amawongolera zitsulo * asanaponyedwe *, kukhala ndi kulolerana kowoneka bwino * pakanthawi * kukonza, ndikutsimikizira kukhulupirika kwa microstructure * pambuyo * chithandizo cha kutentha.
Chifukwa Chimene Stellite Sichingokhala "Chitsulo Cholimba" -Ndi Chosankha Chadongosolo
Tawonapo zinthu zambiri zomwe zidalephera kutumizidwa pomwe makasitomala adatchulapo "Stellite-faced" koma adavomereza zokutira zamtundu wa cobalt zomwe zimagwiritsidwa ntchito kudzera pa plasma spray. Chotsatira? Kuphulika pa 3,200 psi, kutayika kwa mipando isanakwane, ndi nthawi yosakonzekera. Kuchita kwa Real Stellite kumayamba ndi zinthu zambiri-osati kuvala. AMS 5387 (Stellite 6B) imapereka kuuma kwa Rockwell C 38-44 * mumkhalidwe wa as-cast *, ndi kukana kwapadera kuphulika, dzimbiri, ndi kutopa kwamafuta. Koma zimangofunika ngati gulu la valve loyambira likhalabe lolimba - komanso ngati malo a Stellite amakhala omangika ndi zitsulo kudzera panjinga yotentha. Izi zimafuna kuwongolera bwino kwambiri kuchuluka kwa kulimba, chithandizo cha kutentha pambuyo pa weld, ndi mawonekedwe apakati panthawi yopangira ndalama. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Chigawo chilichonse cha valavu cha Stellite chimayamba ndi ma ingots ovomerezeka a T800, otsimikiziridwa ndi kusanthula kwazithunzi asanasungunuke. Palibe gulu lomwe limapitilira popanda kutsatiridwa kwathunthu: nambala ya kutentha, tsiku lothira, ndi zipika zoziziritsa zomwe zasungidwa zaka 10+.
Kuphatikiza Koyima Kumathetsa Zomwe Mafakitole Ambiri Amawona Monga Mavuto Osiyana
Ogulitsa ambiri amagawirana kwa wogulitsa m'modzi, makina a CNC kupita kwa wina, ndikuwunika komaliza kwa wachitatu. handoff iliyonse imayambitsa chiopsezo: kusagwirizana kwa 0.02 mm pakati pa mpando wobowola ndi disc axis kumakhala kusokonezeka kwakukulu; Kusagwirizana kwa 5-μm pamwamba pa nkhope yosindikiza kumayambitsa kutayikira pang'ono poyambira. QINGDAO QIANGSENYUAN ndi eni ake unyolo wonse—kuyambira mchenga ndi ndalama zopangira ndalama mpaka kutembenuka kwa CNC kosiyanasiyana, kutembenuka mwamphamvu, ndi kutsimikizira kowona. Panyumba zokhala ndi ma valve othamanga kwambiri, amaponyera thupi mu AMS 5387, ziboliboli zowopsa pamakina, zimachotsa kupsinjika, kenako zomaliza pamakina pogwiritsa ntchito zida za diamondi zokhala ndi mayankho a CMM. Chotsatira? Nkhope zokhala pansi zomwe zimagwiridwa ndi ± 0.005 mm flatness, zinkakhala ndi concentricity mkati mwa 0.01 mm, ndi pamwamba pa roughness Ra ≤ 0.4 μm-zotsimikiziridwa zisanachitike passivation yomaliza.
Kutsimikizika Kwapadziko Lonse Kumapambana Ziphaso Zapepala Nthawi Zonse
Chitsimikizo cha ISO 9001 chimakuwuzani kuti njira ilipo. Sizikuwuzani ngati mpando wa Stellite umapulumuka maulendo 12,000 mu ntchito ya gasi wowawasa-kapena ngati tsinde la diski limakana kuvala movutikira likakwera chokwera pamapampu akunyanja. Tidayesa ma valavu a QINGDAO QIANGSENYUAN a Stellite 6B pamodzi ndi ochita nawo mpikisano atatu pakuyesa moyo mwachangu: mizungulire 8,000 pa 5,000 psi, 120 ° C, yokhala ndi mchenga wodzaza ndi 5%. Opikisana awiri adawonetsa kukokoloka kwa mipando pambuyo pa 3,500 kuzungulira. Imodzi idatsika pa 2,800 psi pakutsimikizira kozizira koyambira. Magawo a QINGDAO QIANGSENYUAN adadutsa mizunguliro yonse 8,000 popanda kusintha koyezera pamipando yapampando-kutsimikiziridwa ndi profilometry yowunikira isanakwane komanso pambuyo poyesa. Chinsinsi chawo? Osati kusankha kwa aloyi - koma kukhazikika kowongolera pakuponya, komwe kumachepetsa kugawanika kwa carbide, ndi kutembenuka molunjika komwe kumateteza kupsinjika kotsalira pamawonekedwe osindikiza.
Zomwe Muyenera Kufunsa Musanayambe Kuchita Pafakitale Yoyang'anira Valve Stellite
Osafunsa "Kodi mumapanga zigawo za Stellite?" M'malo mwake funsani izi:
- Kodi mungandipatse malipoti oyesa mphero pa kutentha kulikonse komwe timagwiritsa ntchito? (Osati ziphaso zokha—zamankhwala ndi makina athunthu)
- Kodi kupatuka kwanu kwakukulu kovomerezeka pampando wapampando ndi kotani - ndipo mumayezera bwanji? (CMM? Optical interferometer? Pamwamba mbale + chizindikiro?)
- Kodi mumayesa akupanga pa matupi onse a Stellite-cast kuposa makulidwe a khoma la 50 mm? (Zofunikira pakuzindikira kutsika kwapansi pamadzi)
- Kodi mumatsimikizira bwanji kukhazikika kwa dimensional pambuyo pa chithandizo cha kutentha? (Tikufuna masikanidwe a CMM pambuyo pa chaka pamagawo oyamba)
- Kodi mumayitanitsa bwanji ma geometries amtundu wa AMS 5387—ndipo tingavomereze ma prototypes ankhani yoyamba tisanatulutse?
Awa si mafunso ongoganizira chabe. Ndi zosefera zomwe zimalekanitsa kuthekera kokonzekera kupanga ndi zonena zamabulosha. QINGDAO QIANGSENYUAN amayankha chilichonse ndi ndondomeko zolembedwa—osati malonjezo. Gulu lawo lopanga mainjiniya limawunikanso ma callout a GD&T mwachindunji ku SolidWorks, amawonetsa mikangano yomwe ingachitike asanapangidwe nkhungu, ndikugawana zidziwitso zowunika - osati masitampu obiriwira / ofiira / olephera.
Kuwongolera kodalirika kwa mafakitale sikuyambira pakukhazikitsa. Zimayambira pomwe aloyiyo imakwaniritsa cholinga chake - ndipo imakhala pamenepo mpaka 10,000 kuzungulira, zaka 20, ndi nthawi zitatu zokonza. Ngati pulojekiti yanu yotsatira ikufuna kukhazikika kwa Stellite-grade popanda kusokoneza kukhulupirika, yang'anani fufuzani valavu Stetellite fakitale amene amaona zitsulo, makina, ndi metrology monga njira imodzi yosalekeza—osati madipatimenti atatu osiyana. Zimenezo si zapamwamba. Ndilo maziko a machitidwe ofunikira kwambiri.
