Lapho abantu abaningi bezwa 'ukwenziwa kwensimbi', babona ngeso lengqondo indoda egqoke iphinifa lesikhumba ethela uketshezi olukhazimulayo esikhunjeni sesihlabathi. Akulungile lokho, kodwa kufana nokuchaza imoto njengebhokisi elinamasondo. Indaba yangempela, leyo egcina izitolo njengezethu zisebenza amashumi eminyaka, yenzeka kudala ngaphambi kokuba kuthelwe amanzi futhi emva kwesikhathi eside kuphole. Kukukukhethwa kwezinto ezibonakalayo, ubunjiniyela besikhunta, idizayini yesango, kanye nokungenakugwemeka, kwesinye isikhathi okubiza kakhulu, ukuxazulula izinkinga. Amaklayenti amaningi eza kithi ecabanga ukuthi imayelana nokuncibilika nokubumba insimbi. Iqiniso liwukuthi, ukulingisa kuvame ukuba yingxenye elula; yikho konke okusizungezile okuchaza impumelelo noma inqwaba yezilahliwe ezibizayo.
Isikhunta nguMlayezo
Ake sikhulume isikhunta. Ukukhetha phakathi ukubunjwa kwegobolondo futhi ukutshala imali akukhona nje ukukhetha; kuyisinqumo esibalulekile esibeka ukubekezelelana, ukuqedwa kwendawo, kanye nejometri. Sisebenza sobabili endaweni yethu. Ukubumba igobolondo, kusetshenziswa isihlabathi esimbozwe inhlaka, kuhle kakhulu ekugijimeni kwevolumu ephezulu yezingxenye ezinjengemizimba yamavalvu noma izikhala zamagiya. Uthola isiphetho esihle futhi ukonga uma kuqhathaniswa. Kodwa ukuzinza kwe-dimensional? Inemingcele yayo, ikakhulukazi ezindimeni eziyinkimbinkimbi zangaphakathi. Ubhekene nesihlabathi, phela, futhi singaguquguquka noma siguguleke.
Ukutshala imali, inqubo ye-wax elahlekile, iyisilwane esihlukile. Siyisebenzisela izinto eziyinkimbinkimbi-ama-impeller, ama-turbine blades, izingxenye zensimbi yokuhlinza. Igobolondo le-ceramic lithwebula imininingwane ngokungafani nalutho. Kodwa inqubo ayithetheleli. Iphutha elincane kuphethini ye-wax liphindaphinda kahle engxenyeni yokugcina yensimbi. Ngikhumbula inqwaba yabakaki bensimbi engagqwali lapho saba nokungafani okuncane ekuhlanganiseni kwe-wax. Ibingabonakali ngeso lengcina, kodwa idale ukukhanya kwezinwele kukho konke ukulingisa kulayini wokuhlukanisa. Lonke lolu hlelo ludinga ukuqedwa ngesandla, okwenze imodeli yezindleko. Siyini isifundo? Ekubunjweni kokutshalwa kwezimali, ingxenye yakho yokuqala ephelele iphethini ye-wax, hhayi eyensimbi.
Yilapho ukuzizwisa komsebenzi osekunesikhathi eside kuphumelela khona. E-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), njengoba senze lokhu iminyaka engaphezu kwengu-30, sakhe imitapo yolwazi yamapharamitha wezinqubo zamajiyometri ahlukahlukene. Akuwona umlingo; iwuhlu lwamaphutha nezilungiso ezedlule. Ukuze uthole umklamo omusha we-impeller ku-a ingxubevange esekwe nickel, asiqali ku-zero. Siyazi ukuthi ingxubevange incipha kanjani, ukuthi igobolondo le-ceramic lisabela kanjani ekushaqekeni kwalo okushisayo, futhi cishe lapho kufanele kubekwe khona izimbobo ukuze kugwenywe ukungena kwegesi. Kufundile ukuqagela, kepha imfundo ibibiza.
Okubalulekile Akulona Nje Ishidi Elicacisiwe
Amaklayenti asithumelela imininingwane ebalulekile: ASTM A216 WCB noma 316 Stainless. Yilokho umugqa wokuqala. I-Cast iron, i-carbon steel, insimbi engagqwali-bonke baziphatha ngendlela ehlukile esimweni sokuncibilika. Uketshezi, ukuncipha, ukuthambekela kokudabula okushisayo. Insimbi enekhabhoni ephezulu ithulula kahle kodwa incipha njengokuhlanya, idinga izikhuphukeli ezibalwe ngokucophelela ukuze ziphakele ukuqina. Thola usayizi wesikhuphukeli noma indawo engalungile, futhi uthola ukushwabana kwe-porosity ngaphakathi kokulingisa. Kungase kudlule okubonakalayo, kodwa kuzohluleka ngaphansi kwengcindezi noma ukukhathala.
Izinselelo zangempela ziza nezipesheli, njengazo ama-alloys asekelwe ku-cobalt. Ivamise ukuba ezezindawo eziyingozi kakhulu—ukushisa okuphezulu, ukugqwala, ukuguga. Iwindi labo lokusakaza lincane. Kushisa kakhulu, futhi ushisa izakhi ezibalulekile noma ubangele ukukhula okusanhlamvu ngokweqile. Kupholile kakhulu, futhi insimbi ngeke igcwalise izingxenye ezincane. Sake saba nephrojekthi yomkhono wepompo ongagugi kungxubevange ye-Co-Cr. Ukuthela okumbalwa kokuqala kuholele ekuvaleni okubandayo nokungahambi kahle. Insimbi yayibanda kakhulu. Isixazululo sasingelona nje ukuphakamisa isithando somlilo. Kwadingeka sihlele kabusha isistimu yokufaka isango ukuze insimbi ingene emgodini wesikhunta ngokushesha nangesiyaluyalu, kuyilapho sishisisa ngaphambili amagobolondo e-ceramic abe izinga lokushisa elithile eliphakeme. Kwathatha izikhathi ezintathu. Ishidi lokucaciswa alikutsheli lokho.
Lokhu ukusondelana impahla yingakho isitolo enikeza kokubili ukubunjwa kwensimbi futhi CNC imishini ngaphansi kophahla olulodwa kunenzuzo. Siyazi ukuthi umshini wokulingisa uzowenza kanjani. Leyo ingxubevange ye-cobalt? Kunzima kakhulu ukwenza umshini ngemuva kokusakaza. Ngokwazi lokho, singase silungise inqubo yokwelapha ukushisa ngemva kokusakazwa ukuze sikuthambisa kancane ukuze sikwazi ukusebenza kahle, bese senze ukwelashwa kokugcina kokuqina. Uma amaqembu okulingisa nawomshini kuyizinhlangano ezihlukene, leyo loop yempendulo ihamba kancane futhi iyabiza.
I-Handoff: Ukusuka ekusakazeni kuya ku-CNC
Lesi yisixhumi esibonakalayo esibucayi, esivame ukunganakwa. Ukulingisa akuyona ingxenye eqediwe; kuyinto engenalutho yomumo we-net-net.
