Lapho ama-hydraulic systems ehluleka ngaphansi kwengcindezi, lapho izindlu zamaphampu ziqhekeka ngemva kwezinyanga ezingu-18—hhayi iminyaka eyishumi—futhi lapho amawintshi eshafta othulini lwezimayini, akuvamile ukuba umsuka uklanywe. Kuwukumelana nokugqoka. Hhayi "okwanele ngokwanele" ukumelana nokugqoka. Hhayi "i-alloy ejwayelekile" ukumelana nokugqoka. Uhlobo olubamba ukuqina kohlangothi ku-220 MPa, lumelana nenyongo ekudakaleni okubi, futhi lusinda ekubhayisikilini okushisayo ngaphandle kwe-microcracking. Kungakho onjiniyela kulo lonke elaseNyakatho Melika, eJalimane, nase-Singapore bengamane bacinge *izingxenye ezingagugi*. Bafuna a imboni yezingxenye ezingagugi ngesiyalo se-metallurgical esifakazelwe-hhayi nje amandla okwenza imishini.
Ikhono lezinto ezibonakalayo alikho ongazikhethela lona—iphoyinti lokuhlola lokuqala
Sibone amaphrojekthi amaningi egxilile esigabeni sokubuyekezwa kwempahla: umbhobho we-cobalt-nickel wenqatshiwe ngenxa yokuhlukaniswa kwekhabhoni ngaphandle kwe-spec; indlu yephampu ye-AMS 5387 eyehluleka ukuhlola isifutho sikasawoti ngenxa yokungaguquki kokusabela kokwelapha ukushisa; ipulaki ye-T800 alloy ebonisa ukuguguleka ngaphambi kwesikhathi ngenxa yokuthi i-as-cast microstructure ayinakho ukuhlakazeka kwe-carbide efanayo. Lawa akuwona amaphutha okukhiqiza. Ziyigebe lamakhono ezinto ezibonakalayo. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ama-alloys asekelwe ku-cobalt “awaphathwa.” Ziyabuswa—ngokuthola impahla eluhlaza eqinisekisiwe, ukulandelela umlando wokushisa odidiyelwe abahlinzeki, kanye nokuqinisekiswa kwe-spectrographic kweleveli yenqwaba. Konke ukusakazwa kwe-AMS 5387 kuqala ngokuhlaziywa kwe-ncibilika okufakwe ku-ASTM A970. Yonke ingxenye ye-T800 ithola imephu ye-microhardness yangemuva komshini kuzo zonke izigaba ezintathu eziphambene. Lokhu akukona ukudlula ngokweqile. Kuyindlela oqinisekisa ngayo ubuqotho obungaphezulu obungu-48 HRC kuthiphu ye-cobalt alloy nozzle engu-12-mm-diameter—ngaphandle kokudela ukuqina okuyinhloko.
Ukuhlanganiswa okuqondile kusho ukuthi akukho ukulahlekelwa okuncane—ukushintsha okulawulwayo nje
Abanye abahlinzeki bakhipha izinsiza. Abanye benza imishini yangaphandle. Ukuqeda imithombo embalwa yangaphandle. I-handoff ngayinye yopha ngokunemba: ukuhlanekezela okushisayo phakathi kwezimo ezisansimbi nezinomshini, ukulahlekelwa ubuqotho obungaphezulu ngesikhathi sokugaya kwesibili, ukungahambi kahle kwe-GD&T kusukela ekulungisweni kabusha. I-QINGDAO QIANGSENYUAN isebenza ngaphansi kophahla olulodwa—ukufakwa kwesihlabathi, ukufakwa kwe-investimenti, i-CNC ye-axis eminingi (okuhlanganisa i-5-axis contouring yamavolumu epompo yangaphakathi), ukwelashwa kokushisa, nokuqedwa kwangaphezulu njenge-HVOF noma ukugaya ngokunemba. Uma indlu yesilinda yephampu ye-piston idinga isilinda esingu-±0.015 mm ku-320-mm bore *kanye* ne-63 Ra surface finishing ezindaweni ezibalulekile zokuvala, lolo chungechunge lokubekezelela luhlala lungaphakathi. Akekho umthengisi wangaphandle ohumusha "indawo ebucayi" ngendlela ehlukile. Akukho ukubambezeleka kwezinto eziphazamisa ukukhululeka kwengcindezi yokushisa. Umphumela? Ingxenye efika ilungele ukuhlolwa kokusebenza—hhayi ukusebenza kabusha.
Ukugxila kwesizinda kunikeza ukuqonda kobunjiniyela—hhayi nje imidwebo
“Senza izingxenye ezingagugi” akucacile. “Sinjiniyela amavalvu okucindezela ama-high-cycle manifold hydraulic asebenza kubha engu-350, izindlu zamasilinda zamaphampu odaka oluphindwe kathathu aphatha udaka lwesihlabathi nomthamo ongu-40%, kanye namarola e-winch center shaft wezimoto zobunjiniyela ezingamathani angu-50 ezisebenza amahora angu-22/ngosuku ku-30°C kuya ku-+60°C angakwazi ukusebenza. Lokhu kucaciswa kulungisa yonke into: isu lendlela yamathuluzi (ukugaya okuphakelayo okuphezulu ngokumelene nokuqedwa kokuhamba kancane kwama-alloys e-cobalt), iphrothokholi yokuhlola (ukulandelana kokuhlola kwe-CMM okuthuthukiselwe imizimba yamavalvu anezindonga ezincane), ngisho nokupakisha (i-crating-dampened-dampened for cast cast iron pump foundations). Amakhasimende awasithumeli amafayela e-CAD nethemba. Basithumelela imibiko yokwehluleka, imijikelezo yomsebenzi, imininingwane yekhemistri ewuketshezi—futhi siphendula ngezincomo zebanga lezinto ezibonakalayo, amafasitela ezikhathi zokukhulula ingcindezi, nama-callout e-GD&T abonisa ukulayishwa komhlaba wangempela—hhayi nje i-ISO 2768.
Ukuthembeka kuqala ngaphambi kokuthi kundiza i-chip yokuqala
Ukulandeleka akuwona umsebenzi wamaphepha. Ukwazi ukuthi ipulaki ye-cobalt alloy kuvalvu yakho yokulawula uwoyela ongasogwini yabelana ngenombolo yayo yendawo yokuphatha ukushisa kanye nekhuphoni lokuhlola eliqinile eligcinwe kungobo yomlando iminyaka eyi-10. Imibiko ye-CMM eboshelwe ekulungisweni kwezinombolo ze-serial, izilinganiso zamehlo eziqinisekiswa ngokumelene nezikali eziyinhloko ezilinganiswa masonto onke, nokuhlolwa kokugcina okubonakalayo okwenziwa ngaphansi kokukhanyisa kwe-LED okungu-1000-lux okukhuliswe okungu-10x ukuze kutholwe ukonakala kwendawo. "Asifinyeleli izindinganiso." Sizishumeke: Izilawuli zenqubo ye-ISO 9001, ukuqinisekiswa kwe-ASME B16.34-okuthobela umzimba wamavalvu, kanye nemibhalo ye-PPAP eqondene nekhasimende—okuhlanganisa nezitifiketi zezinto ezibonakalayo, imibiko ye-NDT, namarekhodi okuhlola asebenzayo. Uma imigqa yesikhathi yokulethwa ibalulekile—njengoba yenza kuma-retrofit futha noma ukushintshwa kwewintshi ezimeni eziphuthumayo—ukuhlelwa kokugeleza komsebenzi okunciphile kanye nokuhlelwa okungenasibhafa kugcina ukwenzeka kwesibonelo kanye nama-oda evolumu emaphakathi ehamba ngendlela. Azikho izinkokhelo ezisheshayo. Cha "kuncike kumthamo." Izinsuku ezisanda kuzibophezela, zihlangene.
Isikhathi sokusebenza sezimboni asinqotshwa ngokuthengwa okusheshayo. Ivikelwe ngezingxenye ezingagugi ngaphambi kwesikhathi—ngoba ukumelana kwazo nokugqokwa kwakhiwe, akucatshangwa. Lokho kudinga a imboni yezingxenye ezingagugi yakhelwe phezu kokuqina kwe-metallurgical, ukulawula okuqondile, ukuqonda okuqondene nesizinda, kanye nokulandeleka okunganqamuki. Uma i-valve yakho elandelayo yokucindezela, i-pump house, noma i-winch shaft idinga ukuphila ngale kokucaciswa—hhayi nje ukuhlangabezana nakho—qala lapho kuqala ukumelana nokugqokwa: ukukhetha impahla, ukuqhubeka kwenqubo, kanye nokusebenza okubhaliwe. Akusona isithembiso leso. Yindlela umsebenzi owenziwa ngayo.
