Pampu yamagetsi ikalephera m'malo opangira mafuta m'mphepete mwa nyanja - kapena shaft ya winchi ikagwira mkati mwa chofukula migodi - chifukwa chake sichikhala chopangidwa kawirikawiri. Ndi kuvala. Osati kokha kuvala kulikonse: micro-abrasion, galling, matenthedwe kutopa pansi pa 300 ° C cyclic katundu. Ndiko kumene Stellite 6 magawo fakitale kuthekera kumasiya kukhala osasankha. Zimakhala kusiyana pakati pa maola 8,000 a ntchito ndi kulephera koopsa kwamunda.
Taponya ma nozzles a Stellite 6 a ma jakisoni a asidi othamanga kwambiri ku Saudi Arabia-ndikuwawona akupitilira mibadwo itatu yosinthira zosapanga dzimbiri. Tapanga makina a AMS 5387 piston pampu ya silinda ya ma OEM aku Germany omwe amafuna ± 0.015 mm kuzungulira 200 mm m'mimba mwake, okhala ndi Ra ≤0.4 µm pambuyo popera komaliza. Izi siziri zongopeka chabe. Ndi zizindikiro zatsiku ndi tsiku mu malo athu ovomerezeka a ISO ndi makina opanga makina ku Qingdao.
Stellite 6 si "cobalt alloy ina." Mapangidwe ake - pafupifupi 65% Co, 28% Cr, 4% W, kuphatikiza Ni, Fe, ndi C - amapanga matrix a hard chromium carbides ophatikizidwa munjira yolimba ya cobalt. Izi zimapereka kukana kosagwirizana ndi chitsulo-ku-chitsulo, dzimbiri m'malo okhala ndi chloride, komanso kufewetsa kwamafuta mpaka 500 ° C. Koma izi ndi zomwe ogula ambiri amanyalanyaza: kuponya Stellite 6 sikuli ngati kuponya chitsulo. Malo ake osungunuka kwambiri (1,290-1,350 ° C), kutsika kwamadzimadzi, komanso kuchepa kwambiri kumafuna malo apadera, kuwongolera bwino kwa kutentha kwa nkhungu, ndi chithandizo cha kutentha kwa post-cast homogenization. Dumphani sitepe iliyonse-ndipo mumapeza porosity, carbide segregation, kapena brittle interdendritic phases. Tawona makasitomala akukana 40% yamagulu oyamba kuchokera kwa ogulitsa osayenerera. Zokolola zathu pazovuta zamakampani za Stellite 6 zimafika pa 92%+ chifukwa timawongolera zosintha zilizonse: chiphaso chazinthu zopangira (zonse za T800-grade cobalt base alloys traceable to mphero test report), vacuum-melted ingot sourcing, and real-time mather profileing panthawi yolimba.
Kuphatikiza koyima kumalekanitsa mafakitale odalirika a Stellite 6 kuchokera kwa ogulitsa zinthu. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kuponyera, kukonza makina a CNC, ndi kumaliza kumachitika pansi pa denga limodzi - ndi metrology yogawana, kutanthauzira kogwirizana kwa GD&T, ndikuchedwetsa ziro. Makasitomala akatumiza chojambula cha pulagi ya aloyi ya cobalt yomwe ili ndi ma asymmetric kuzizirira komanso kulolerana kwa 0.008 mm pazinthu zisanu za ulusi, sititulutsa zotembenuza. Timayendetsa pa 5-axis DMG MORI NTX 1000, pogwiritsa ntchito zida za PCD zokongoletsedwa ndi ma aloyi a cobalt, ndi laser-in-processing laser kuti atsimikizire makulidwe a khoma musanayambe kupera ID. Palibe wogulitsa akunja amamvetsetsa momwe kupsinjika kotsalira kuchokera pakuponyedwa kumakhudza kupotoza kwa makina pa 320 mm kutalika kwa valve. Timatero-chifukwa timachiponya, kuchitenthetsa, kuchigwiritsa ntchito makina, ndikuchiyang'ana ndi pulogalamu yofanana ya CMM kuyambira pachiyambi mpaka kumapeto.
Zochitika zenizeni padziko lapansi zimatengera zinthu zitatu zomwe sizingakambirane—osati zonena zamalonda. Choyamba: kusasinthasintha kwakuthupi. Magawo onse a Stellite 6 amawunikiridwa mowoneka bwino, kulimba kwa mapu kudutsa magawo osiyanasiyana, ndikutsimikizira kukula kwambewu ya ASTM E112. Chachiwiri: kukhulupirika kwapakatikati. Timatsimikizira malo ovuta pogwiritsa ntchito ma profilometers owoneka - osati ma CMM okha - kuti tigwire ma micro-topography omwe amakhudza kukhulupirika kwa chisindikizo. Chachitatu: kutsimikizira ntchito. Musanatumize, valve iliyonse yokakamiza imayesedwa ndi hydrostatic pa 1.5 × oveteredwa ntchito; nyumba iliyonse yapampu imawunikiridwa ndi helium mass spectrometry. Makasitomala aku North America ndi Europe samafunsa ziphaso - amafunsa malipoti oyesa a batch omwe ali ndi masitampu anthawi, ma ID oyendetsa, ndi masitampu owongolera zida. Timawapulumutsa.
Ngati ntchito yanu ikuphatikiza slurries, nthunzi yotentha kwambiri, kapena kutsitsa kwapang'onopang'ono pamwamba pa 200 MPa, Stellite 6 siinjiniya mopitilira muyeso. Ndi inshuwaransi. Koma inshuwaransi imagwira ntchito pokhapokha ngati woperekayo ali ndi chidziwitso chotsimikizika-osati mabulosha okha. Yang'anani zolembedwa zopambana m'gawo lanu: misonkhano yopopera yogwiritsira ntchito pansi pa nyanja, zodzigudubuza za winch center shaft za ma cranes olemetsa, kapena milomo ya cobalt alloy yazomera zochotsa mchere. Yang'anani ngati ali ndi zivomerezo za AMS 5387-osati ma cert chabe. Tsimikizirani ngati mbiri yawo yabwino ikuphatikiza kutsatiridwa kwathunthu mpaka kuchuluka kwa kutentha kwa ingot ya cobalt. Kenako yerekezerani malangizo operekera: kodi atha kukhala ndi mazenera amasiku ± 3 pamaoda apakatikati popanda kuthamangitsa chindapusa? Ndicho chizindikiro cha choonadi Stellite 6 magawo fakitale-osati malo ogulitsa ntchito okhala ndi zidziwitso za cobalt alloy.
