Kana mainjiniya achinge ataura grey iron cast ye hydraulic valves kana pombi dzimba, ivo havasi kungosarudza chinhu-vari kubheja pakudzikama kwedimensional pasi pe300-bar pressure, kupfeka kuramba mushure me10,000 kushanda kutenderera, uye zero kushivirira kune micro-shrinkage mumaflange anotakura. Ndicho chikonzero kusarudza chakanaka grey iron casting factory haisi yemutengo wakaderera kana inokurumidza kutungamira nguva. Zviri pamusoro pemetallurgical control, process discipline, uye engineering alignment-zvinhu zvitatu zvatakaona zvichikundikana kakawanda kana majekiseni anoenda kumahombekombe pasina akadzamidzirwa tekinoroji tarisiro.
KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tinochina uye tinokandira masimbi egrey zuva nezuva-kwete sezvigadzirwa, asi sekuwedzera kwemaitiro emagetsi ekudzvinyirira. Chikwata chedu chekutanga hachibate ASTM A48 Kirasi 30B sebhokisi rekutarisa. Isu tinoteedzera graphite nodule count per mm², simbisa pearlite zvirimo kuburikidza nemetallografia tisati tarapwa kupisa, uye simbisa simba rekusimba pamaladle ese anodururwa-kwete chete batch samples. Sei? Nekuti piston pombi humburumbira dzimba ine 12% pearlite pachinzvimbo che85–92% inotadza kutanga pasi pemabhasikoro ekupisa. Isu takazviona. Uye isu takavaka maitiro edu kudzivirira.
Chii chinoparadzanisa fekitori yegrey iron yekukanda yakavimbika kubva kune mutengesi wekutengesa kusanganisa kwakamira-kwete mumidziyo chete, asi mukuita sarudzo. Panzvimbo yedu yeISO-yakasimbiswa nzvimbo muQingdao, injinjiniya mumwe chete anotendera mareti emidziyo anosainawo pamishumo yekupedzisira yeCMM yeGD&T callouts seØ42.5±0.015 mm nekushivirira chinzvimbo 0.05 mm zvine chekuita nedatum A-B-C. Hapana handoffs. Hapana kurasikirwa kweshanduro pakati pekugadzira dhizaini nekugadzirisa machining. Kana mutengi akatumira dhirowa yewinch centre shaft roller ine yakavhiringwa 60° helical grooves, timu yedu inomhanyisa simulation * isati yabvumidzwa * patani - uye inomisa njodzi yekuisa mireza iyo inogona kukonzera porosity munzvimbo yegiya mesh. Icho hachisi "rutsigiro." Iyo yakagovaniswa muridzi wekuita basa.
- Kurongeka kwezvinhu kunotangira pachoto-kwete panotakurirwa chikepe. Yese grey iron cast inotakura nhamba yekupisa yakabatana ne spectrographic analysis, kutonhora matanda, uye kuoma mepu muzvikamu zvakakosha.
- Hapana "standard" jecha mold process. Isu tinoshandisa resin-bonded molds kune dzakatetepa-madziro housings (2.8 mm zvishoma), jecha rakasvibirira kune nheyo huru (> 120 kg), uye inodzorwa kutonhora kwemazinga ekushushikana-akakosha flanges-haambofi imwe-saizi-inokwana-zvose.
- Machining haisi post-cast kuchenesa-iyo chaiyo muripo. Isu tinogadzirisa shrinkage inofanotaurwa (0.72% yeHT250), yakaringana kukanganisa mold mu-multi-cavity setups, uye zvakare-muchina unotakura mabhora mushure mekushushikana-kuzorodza annealing kuti ibate kutenderera mukati me0.008 mm.
Vamwe vatengi vanofunga kuti grey iron "iri nyore." Asi kuomarara kunovanda mune izvo: Mutengesi wako anobata sei kusarura kwesarufa mune inorema-chikamu castings? Vanoyera ferrite/pearlite ratio-kana kungotaura kuoma kweBrinell? Vanogona kubata 0.02 mm flatness pane 450 × 320 mm inokwira pamusoro pasina kugaya? Isu takaita kuti vatengi vashandure kwatiri mushure mekutadza kuburitsa katatu kubva kune vatengesi vakapfuura ongororo yekuona-asi vakaendesa zvikamu zvine subsurface graphite flotation iyo yakatsemuka panguva yekuedzwa kwehydraulic pa220 bar. Kugadzirisa kwanga kusiri nani QC. Yakanga iri kudzora zvakanyanya pamusoro pekudurura tembiricha (1380-1410 ° C), inoculation nguva (mukati me20 masekonzi ekutapa), uye mold preheating kuenderana. Aya haasi mafungidziro pane dhatabheti. Vanodzidzira rhythms.
Nezvekushandisa zvakakosha-mafuremu epombi yemumunda wemafuta, nharembozha hydraulic manifolds, marine bilge system mavharuvhu - fekitori yako yekukandira simbi inofanirwa kushanda pamharadzano yesimbi, geometry, uye kurodha kwenyika chaiyo. Izvi zvinoreva kugonesa kuteedzera kwekukanda kunopesana nematipi ekuyedza mabhawa * pakupisa *, kushandisa michina yekuyeresa yakarongeka-kwete macaliper-kuti iongororwe kekupedzisira, uye kubata kuzere kuteedzera kubva kune ladle kuenda kune yatumirwa. Zvinoreva kunzwisisa kuti AMS 5387 cobalt alloy housings inogovana zvakafanana machining zvigadziriso uye thermal manejimendi mapuroteni seyawo grey iron mamwe-nekuti dimensional drift inobata zvese zvakaenzana. Zvinoreva kuti "kwete" kune hukasha nguva yekumisikidza kunoratidza njodzi-uye kupa imwe yakatenderwa imwe panzvimbo pevimbiso.
Kana iwe uchida grey iron castings iyo inorarama makore gumi nemashanu munzvimbo dzemahombekombe emvura yemunyu kana kuchengetedza kutendeseka kwechisimbiso mushure me50,000 yekumanikidza kutenderera, tanga nekuita pachena-kwete nhamba dzekabhuku. Tarisa magwaro ekuongorora akanyorwa, kwete zvitupa chete. Tarisa kuti "chaiyo" inosanganisira microstructure control, kwete kungoshivirira kwakasimba. Uye yeuka: iyo inodhura zvakanyanya kukanda haisi iyo ine yakakwira unit mutengo. Ndiyo inononoka kutumwa, inokonzeresa basa remumunda, kana kukanganisa kuchengetedzwa kwehurongwa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inovaka grey iron zvikamu uko kutadza kusiri sarudzo-saka kuvimbika hakusi chinhu. Ndiyo yekutanga.
