U hloka likarolo tsa tšepe tse nepahetseng-ka potlako? Eseng "ka potlako bakeng sa ho lahla." Feme e potlakileng ea ho kenya chelete e bolela ho fetola likarolo tse rarahaneng, tse nang le bots'epehi bo phahameng joalo ka matlo a AMS 5387 cobalt alloy pump ho tloha ho hula ho isa thomellong ka nako e ka tlase ho matsatsi a 21. Seo ha se ho potlakisa. E nchafatsa kemiso ea nako.
Re fane ka li-batch tse fetang 1,200 tse fetohang ka potlako ho tloha ka 2020-haholo li-valve tsa khatello, li-cylinder pump cylinder housings, le li-winch center shaft rollers bakeng sa li-OEM tsa hydraulic ho pholletsa le Amerika Leboea le Europe. Se etsang hore e sebetse ha se lebelo feela. Ke kamoo ho lahla, ho sebetsa ka mechine, le ho laola metallurgical ho notlelaneng hammoho.
Litsi tse ngata li nka ho etsa matsete e le mokhoa o ikemetseng. Li tšela lipaterone tsa boka, likhetla tsa mollo, li samente, ebe li isoa lebenkeleng la mechine—haeba li le teng. Ho lieha ho nka nako: kemiso ea kalafo ea mocheso, mochini o hokahanyang litekanyo (CMM), likheo tsa ho latella lintho. Re bone moreki a le mong a ema matsatsi a 47 ho netefatsa botenya ba lebota holim'a plug ea oli le khase. Sebopeho sa bona se ne se hloka mamello ea ± 0.05 mm karolong ea cobalt-nickel ea bophara ba 120 mm. Ho lieha ho ne ho se ka lebaka la ho lieha - e ne e le ho arohana.
Tharollo ea rona e qala ka kopanyo e otlolohileng - eseng joalo ka buzzword, empa joalo ka ts'ebetso ea letsatsi le letsatsi. Moralo oa mohlala oa boka o etsahala hammoho le tlhahlobo ea GD&T. Nako ea ho chesa hlobo ea Shell e lumellana le ho fumaneha ha sebōpi *le* bolepi ba CNC spindle load. Lipotoloho tsa kalafo ea mocheso li netefalitsoe esale pele bakeng sa kereiti ka 'ngoe ea alloy-AMS 5387, T800, F22 steel-ka hona ha ho betch e emelang profiling ea mocheso. Ntho e 'ngoe le e' ngoe e kenang ea cobalt alloy ingot e na le litlaleho tse feletseng tsa tlhahlobo ea leloala; karolo e 'ngoe le e' ngoe e phethiloeng e boloka traceability ea boemo bo bongata ho fihlela nomorong ea tefiso ea sebōpi.
Sena se felisa lintlha tse tharo tse tloaelehileng tsa ho hloleha mererong e potlakileng ea ho lahla:
- Dimensional drift between casting and finish machining-e rarolloa ka ho ts'oara mamello ho ± 0.3 mm lifahlehong tse mahlonoko, ebe e sebelisa netefatso ea CMM pele e sila.
- Ho se lumellane ha microstructure ho li-castings tse phahameng tsa alloy-e rarolloa ka litheko tse laoloang tsa ho pholisa ka har'a mohala oa rona oa sebopi o tiisitsoeng oa ISO 9001 le ho rema lifate ka nako ea 'nete ea thermocouple ka ASTM E2862
- Hoa makatsa ka bofokoli bo ka holimo tlhahlobong ea ho qetela-e thibetsoe ka ho hlahlobisisa ha hlobo tsohle tsa likhetla pele li tšela le 'mapa o ikemetseng oa porosity ho 100% ea likarolo tsa X-ray
Ba bang ba ka 'na ba pheha khang ea hore ho kopanya ka thata ho tela ho tenyetseha. Empa ha e le hantle, se fapaneng ke 'nete. Ha moetsi oa pompo oa Europe a ne a hloka li-iteration tse tšeletseng tse ntlafalitsoeng tsa nozzle ea alloy e sa tloaelehang-e 'ngoe le e' ngoe e hloka li-tweaks tsa geometry le netefatso e ntlafalitsoeng ea tsela ea phallo - re ile ra tsamaisa li-prototypes tse felletseng ka matsatsi a 11 e le 'ngoe. Hobaneng? Hobane lienjineri tsa rona li netefalitse monyetla oa ho etsa *nakong ea* tlhahlobo ea CAD — eseng kamora hore lisebelisoa li khaotsoe. Ha ho na redraws. Ha ho sekhechana. Ntlafatso e pheta-phetoang feela ka har'a sistimi e ts'oanang.
Sistimi eo e kenyelletsa matla a mane a mantlha a sebetsang ka tlas'a marulelo a le mong: ho etsa matsete (bakeng sa lijeometri tse rarahaneng ho fihla ho lik'hilograma tse 45), ho lahla lehlabathe (bakeng sa matlo a maholoanyane a meralo), machining a CNC a li-multi-axis (5-axis ka nako e le 'ngoe bakeng sa li-impeller contours), le ho qeta bokaholimo ba ts'ebetso-ho kenyeletsoa le ho roala ha HVOF bakeng sa libaka tse senyehileng le litšepe tse se nang letho. Tsohle li hlophisitsoe ho ASME B16.34, ISO 8502-3, le liprothokholo tsa tlhahlobo tse khethehileng tsa bareki.
Seo bareki ba hlileng ba se botsang-le seo re se arabang pele-ha se "potlako e kae?" Ke "Na u ka tšoara 0.002" holim'a boro ena ha u ntse u boloka botšepehi ba phallo ea lijo-thollo ka har'a fillet? Kapa "Na plug ee ea alloy ea T800 e tla phela ka 15,000 psi cyclic loading ntle le ho qalisoa ha microcrack?" Kapa "Na u na le bopaki bo tlalehiloeng ba hore sehlopha sa hau sa AMS 5387 se kopana le litlhoko tsa maemo a thata tsa AMS 2301?" Re etsa joalo. Nako le nako.
Ts'ebetso ea 'nete ea lefats'e ea ho fana ka thepa e tiisa sena: 94.7% ea li-oda tsa boleng bo bohareng (50-500 pcs) e tsamaisoa ka har'a matsatsi a ± 2 ka letsatsi le ikemiselitseng. Linako tse etellang pele tsa prototype ka karolelano ea matsatsi a 14 ho tloha ho setšoantšo se amohetsoeng ho isa tlhahisong ea sengoloa sa pele - ho kenyelelitsoe tlaleho e felletseng ea likarolo, litifikeiti tsa thepa, le lirekoto tsa NDT li kenyellelitsoe. Ha ho litlatsetso. Ha ho mekhelo.
Ha u sheba pele, bothata ha se bokhoni-ke ho tšoaneleha. Makala a mangata a batla litifikeiti tsa EN 10204 3.2, ho latela melao ea PED 2014/68/EU, kapa ho lokisoa ha API Q1. Ka hona, re ntse re holisa sebaka sa rona sa tlhahlobo ea mokha oa boraro le netefatso ea ts'ebetso e nyalisitsoeng bakeng sa mefuta e nyalisitsoeng ea mochini o nyalisitsoeng - joalo ka lihlopha tse kopaneng tsa li-valve moo selikalikoe se behoang matsete * sebakeng*, ebe se koaheloa ho ts'oana le stem bore.
