Lapho onjiniyela becacisa ukukhishwa kwensimbi empunga yemizimba yamavalvu odonsa amanzi noma amaphampu ezindlu, abagcini nje ngokukhetha into ethile—babheja ukuzinza kohlangothi ngaphansi kwengcindezi yamabha angu-300, ukumelana nokugqoka ngemva kwemijikelezo yokusebenza engu-10,000, kanye nokungabekezeleli nhlobo ukushwabana okuncane kumaflange aphethe umthwalo. Yingakho ukhetha okulungile grey iron casting factory ayimayelana nenani eliphansi kakhulu noma isikhathi sokuhola esishesha kakhulu. Imayelana nokulawulwa kwensimbi, isiyalo senqubo, nokuqondanisa kobunjiniyela—izinto ezintathu esizibonile zehluleka ngokuphindaphindiwe lapho ukulingisa kuthuthela ogwini ngaphandle kokuqondisa kobuchwepheshe okugxilile.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sisebenza ngomshini futhi siphonsa izingxenye zensimbi ezimpunga nsuku zonke—hhayi njengempahla, kodwa njengezandiso ezisebenzayo zezinhlelo zokucindezela okukhulu. Ithimba lethu labasunguli aliphathi i-ASTM A48 Class 30B njengebhokisi lokuhlola. Silandelela isibalo samanodule e-graphite nge-mm² ngayinye, siqinisekisa okuqukethwe kwe-pearlite nge-metallografia ngaphambi kokwelashwa kokushisa, futhi siqinisekise amandla aqinile kukho konke ukuthululwa kweledi—hhayi nje amasampula enqwaba. Kungani? Ngoba indlu yesilinda yepompo ye-piston ene-pearlite engu-12% esikhundleni sika-85–92% ihluleka ngaphambi kwesikhathi ngaphansi kokuhamba kwamabhayisikili ashisayo. Sikubonile. Futhi sakhe inqubo yethu ukuyivimbela.
Okuhlukanisa imboni yokuphonsa yensimbi empunga enokwethenjelwa kumnikezeli webhizinisi ukuhlanganiswa okuqondile—hhayi nje ezintweni zokusebenza, kodwa egunyeni lokuthatha izinqumo. Esikhungweni sethu esiqinisekiswe i-ISO e-Qingdao, lo njiniyela ofanayo ogunyaza izitifiketi zempahla eluhlaza uphinde asayine emibikweni yokugcina ye-CMM yama-callouts e-GD&T afana ne-Ø42.5±0.015 mm enokubekezelela isikhundla okungu-0.05 mm ngokuhlobene nedatha A-B-C. Awekho ama-handoffs. Akukho ukulahleka kokuhumusha phakathi kwedizayini yokusakaza nokusethwa komshini. Uma ikhasimende lithumela umdwebo we-winch center shaft roller enemigqa eyi-helical engu-60° ephazanyiswe, ithimba lethu lenza ukulingisa okuqiniswayo *ngaphambi* kokugunyazwa kwephethini—futhi libeka izingozi zokubeka isikhuphukeli sefulegi ezingase zibangele ukuqina endaweni ye-gear mesh. Lokho akuyona "usekelo." Yabelana ngobunikazi bokusebenza kokusebenza.
- Ukulandelelwa kwempahla kuqala esithandweni—hhayi idokhu lokuthutha. Yonke insimbi empunga iphethe inombolo yokushisa exhunywe ekuhlaziyweni kwe-spectrographic, amalogi esilinganiso sokupholisa, nokuqina kwemephu kuzo zonke izigaba ezibalulekile.
- Ayikho inqubo yesikhunta sesihlabathi "ejwayelekile". Sisebenzisa isikhunta esine-resin-bonded for thin-wall housings (2.8 mm ubuncane), isihlabathi esiluhlaza ezisekelweni ezinkulu (>120 kg), kanye namazinga okupholisa alawulwayo kuma-flange abalulekile engcindezi—akulokothi alingane nosayizi owodwa.
- Ukwenza imishini akukhona ukuhlanzwa kwangemuva—kuyisinxephezelo esinembayo. Silungisela ukushwabana okubikezelwayo (0.72% ku-HT250), okulungele ukuhlanekezelwa kwesikhunta ekusetheni okunezimbotshana eziningi, kanye nokubhoboza umshini othwala kabusha ngemva kokudambisa ingcindezi ukuze ubambe ukujikeleza phakathi kuka-0.008 mm.
Abanye abathengi bacabanga ukuthi insimbi empunga “ilula.” Kodwa ubunkimbinkimbi bucasha emininingwaneni: Umphakeli wakho ukuphatha kanjani ukuhlukaniswa kwesibabule ekubunjweni kwesigaba esisindayo? Ingabe bakala isilinganiso se-ferrite/pearlite—noma bavele babike ubulukhuni bukaBrinell? Angakwazi ukubamba ukucaba okungu-0.02 mm endaweni yokukhweza engu-450 × 320 mm ngaphandle kokugaya? Sibe namakhasimende ashintshela kithi ngemva kokulethwa okuhlulekile okuthathu okuvela kubathengisi abaphumelele ukuhlolwa okubonakalayo-kodwa baletha izingxenye ezine-subsurface graphite flotation eziqhekekile ngesikhathi sokuhlolwa kwe-hydraulic kubha engu-220. Ukulungiswa kwakungeyona i-QC engcono. Bekuwukulawula okuqinile ekuthululeni izinga lokushisa (1380–1410°C), isikhathi sokujova (phakathi kwamasekhondi angu-20 wokuthepha), kanye nokuvumelana kokushisa kwangaphambi kwesikhunta. Lena akuyona imininingwane egciniwe. Benza izigqi.
Kuzinhlelo zokusebenza ezibaluleke kakhulu—amafreyimu ephampu asendaweni kawoyela, ama-hydraulic crane manifolds, amavalvu esistimu ye-bilge yasolwandle—imboni yakho yokufaka insimbi empunga kufanele isebenze ezimpambanweni zomgwaqo ze-metallurgy, ijiyomethri, nokulayisha komhlaba wangempela. Lokho kusho ukuqinisekisa ukulingisa kokulingisa ngokumelene namabha okuhlola angokwenyama *ngokushisisa ngakunye*, kusetshenziswa imishini yokulinganisa exhumanisayo—hhayi ama-caliper—ukuhlola okokugcina, nokubamba ukulandeleka okugcwele kusukela ku-ladle kuya ekuthunyelweni. Kusho ukuqonda ukuthi izindlu ze-AMS 5387 cobalt alloy zabelana ngokulungiswa okufanayo kwemishini kanye nezinqubo zokuphatha ezishisayo njengozakwabo bensimbi empunga—ngoba ukukhukhuleka kwe-dimensional kuthinta kokubili ngokulinganayo. Kusho ukuthi “cha” ezikhathini ezinolaka lapho ukumodeliswa kokuqinisa kubonisa ubungozi—futhi kunikeze enye indlela eqinisekisiwe esikhundleni sesithembiso.
Uma udinga insimbi empunga esinda eminyakeni engu-15 ezindaweni zamanzi anosawoti asogwini noma ulondoloze ubuqotho bophawu ngemva kwemijikelezo yengcindezi engu-50,000, qala ngokubonisa ngale kwenqubo—hhayi izinombolo zekhathalogi. Bheka amaphrothokholi okuhlola abhaliwe, hhayi nje izitifiketi. Qinisekisa ukuthi "ukunemba" kufaka phakathi ukulawulwa kwesakhiwo esincane, hhayi nje ukubekezelela okuqinile. Futhi khumbula: ukusakaza okubiza kakhulu akukhona okunezindleko zeyunithi ephezulu. Yiyo ebambezela ukugunyazwa, icuphe ukusebenza kabusha kwenkambu, noma efaka engozini ukuphepha kwesistimu. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha izingxenye zensimbi empunga lapho ukwehluleka kungeyona inketho—ngakho ukwethembeka akusona isici. Yisisekelo.
