Xa inkqubo ye-hydraulic ihluleka phantsi koxinzelelo oluphezulu, i-culprit ayinqabile ipompo okanye i-motor-ngokuqhelekileyo i-valve yokukhangela. Yaye xa eso sivalo siguga ngeentsuku endaweni yeminyaka, iinjineli ziyilanda le ngxaki kwinto enye: ukungaqini ngokwaneleyo komphezulu. Yiyo loo nto i-cobalt esekwe kwi-Stellite alloys-ingakumbi i-AMS 5387 kunye ne-T800 amabanga-ayengaxoxiswana kwiivalvu ze-industrial check valves eziphethe ulwelo olurhabaxa, ukukhwela ibhayisekile nge-thermal, okanye i-backpressure eqhubekayo. Kodwa ukukhangela okuthembekileyo khangela ivalve Umzi-mveliso weStellite amaqabane ayikho malunga nokufumana nayiphi na i-Foundry eneziko. Imalunga nokuchonga izixhobo ezilawula i-metallurgy *phambi* kokuphosa, ukubamba ukunyamezelwa kwe-dimensional *ngexesha* lokwenza, kunye nokuqinisekisa imfezeko ye-microstructure *emva* konyango lobushushu.
Kutheni iStellite ingeyiyo nje “iNtsimbi eQinisayo”—Lukhetho lweNqanaba leNkqubo
Siye sabona uninzi lokusilela kwintsimi apho abathengi bachaza "ubuso beStellite" kodwa bamkelwe ukoleka kwe-cobalt eqhelekileyo kusetyenziswe ngesitshizi seplasma. Isiphumo? I-Spalling kwi-3,200 psi, ukuvuza kwesihlalo ngaphambi kwexesha, kunye nexesha lokuphumla elingacwangciswanga. Ukusebenza kweReal Stellite kuqala ngezinto ezininzi-hayi ukugquma. I-AMS 5387 (i-Stellite 6B) ihambisa i-Rockwell C 38–44 ubulukhuni *kwimeko ye-as-cast*, ngokuxhathisa okukhethekileyo kwi-galling, i-corrosion, kunye nokudinwa kwe-thermal. Kodwa loo nto ibalulekile kuphela ukuba isiseko somzimba wevalve sigcina ukuqina kwesakhiwo-kwaye ukuba indawo yeStellite ihlala ibotshelelwe ngebhayisekile eshushu. Oko kufuna ulawulo oluchanekileyo malunga nesantya sokuqina, unyango lobushushu emva kwe-weld, kunye nokusasazwa kobuso ngexesha lotyalo-mali. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke icandelo levalve yetshekhi ye-Stellite iqala ngeengots eziqinisekisiweyo ze-T800 zengxubevange, ziqinisekiswe ngohlalutyo lwe-spectrographic ngaphambi kokunyibilika. Akukho bhetshi iqhubelekayo ngaphandle kokulandelelwa ngokupheleleyo: inombolo yobushushu, umhla wokugalela, kunye nezigodo zokupholisa ezigcinwe kwi-10+ yeminyaka.
Udibaniso oluthe nkqo luSombulula Oko uninzi lweefektri eziPhatha njengeengxaki ezohlukeneyo
Uninzi lwababoneleli banikezela ukuphosa kumthengisi omnye, umatshini weCNC uye komnye, kunye nokuhlolwa kokugqibela ukuya kwisithathu. I-handoff nganye yazisa umngcipheko: ukungahambi kakuhle kwe-0.02 mm phakathi kwesihlalo kunye ne-disc axis iba yintlekele yokuhamba ngokutenxa; Ukungahambelani komphezulu we-5-μm ebusweni bokutywinwa kubangela ukuvuza okuncinci ekuqaleni. I-QINGDAO QIANGSENYUAN ingumnini wekhonkco lonke-ukusuka kwisanti kunye nokuphosa utyalo-mali ukuya kwi-multi-axis ye-CNC yokujika, ukuguqula kanzima, kunye nokuqinisekiswa kwe-contour optical. Kwizindlu zevalve yoxinzelelo oluphezulu, baphose umzimba kwi-AMS 5387, iibhori ezibukhali kumatshini, benza i-annealing yoxinzelelo, emva koko bagqibezele umphezulu wokutywina usebenzisa isixhobo sedayimane kunye nengxelo ye-CMM engaphakathi kwinkqubo. Isiphumo? Ubuso bezihlalo ezibanjelwe kwi-± 0.005 mm flatness, zithwala ukugxila ngaphakathi kwe-0.01 mm, kunye nobunzima bomhlaba u-Ra ≤ 0.4 μm-uqinisekisiwe phambi kokugqithisa kokugqibela.
Ukuqinisekiswa Kwehlabathi Lokwenyani Kubetha iziQinisekiso zePhepha ngalo lonke ixesha
Isiqinisekiso se-ISO 9001 sikuxelela inkqubo ekhoyo. Ayikuxeleli ukuba isihlalo se-Stellite sisinda kwimijikelo ye-12,000 kwinkonzo yerhasi emuncu-okanye nokuba isiqu sediski siyaxhathisa ukunxitywa xa sixhonywe ngokuthe nkqo kwi-skids yepompo engaselunxwemeni. Siye savavanya iivalve ze-Stellite 6B ze-QINGDAO QIANGSENYUAN kunye nabakhuphisana abathathu ekuvavanyeni ubomi obukhawulezileyo: Imijikelezo eyi-8,000 kwi-5,000 psi, i-120 ° C, kunye ne-5% yesanti ekrwada. Abantu ababini abakhuphisana nabo babonise ukhukuliseko lwezihlalo olunokulinganiswa emva kwemijikelo engama-3,500. Enye ivuze kwi-2,800 psi ngexesha lokuqinisekiswa kokuqala okubandayo. Iiyunithi ze-QINGDAO QIANGSENYUAN zigqithise yonke imijikelezo ye-8,000 ngaphandle kotshintsho olunokulinganiswa kwijometri yesihlalo-eqinisekiswe kwangaphambili kunye ne-post-test optical profilometry. Imfihlelo yabo? Ayisiyiyo nje into ekhethiweyo yokukhetha i-alloy-kodwa isalathiso esilawulwayo esilawulwayo ngexesha lokuphosa, okunciphisa ulwahlulo lwe-carbide, kunye nokuchaneka okuqinileyo okugcina uxinzelelo lwentsalela yoxinzelelo kwindawo yokutywinwa.
Eyona nto kufuneka uyibuze ngaphambi kokubandakanya iCheck Valve Stellite Factory
Sukubuza "Ngaba uyazenza iinxalenye zeStellite?" Buza ezi ndawo:
- Ngaba ungabonelela ngeengxelo zovavanyo lokusila kulo lonke ubushushu obusetyenzisiweyo kwi-odolo yethu? (Ayizozatifikethi kuphela-idatha epheleleyo yeekhemikhali kunye neyomatshini)
- Luluphi ukutenxa kwakho okuphezulu okuvumelekileyo kwisitulo sobuso obuthe tyaba-kwaye uwulinganisa njani? (CMM? I-interferometer ye-Optical? Ipleyiti yomphezulu + isalathisi?)
- Ngaba uyalwenza uvavanyo lwe-ultrasonic kuyo yonke imizimba ye-Stellite-cast ngaphezulu kwe-50 mm ubukhulu bodonga? (Kubalulekile ukubona ukushwabana komphezulu ongaphantsi komhlaba)
- Uqinisekisa njani ukuzinza kwe-dimensional emva konyango lobushushu? (Sifuna iskena seCMM emva kokugqiba kumacandelo enqaku lokuqala)
- Ngowuphi ubungakanani obuncinci boodolo bakho kwiijometri ze-AMS 5387-kwaye singavuma inqaku lokuqala leprototypes phambi kokukhululwa ngokupheleleyo?
Le ayiyomibuzo yethiyori. Zizihluzi ezahlula amandla okulungela imveliso kumabango enqanaba lencwadana. QINGDAO QIANGSENYUAN iphendula nganye ngeenkqubo ezibhaliweyo—kungekhona izithembiso. Iqela labo lobunjineli liphonononga ii-callouts ze-GD&T ngokuthe ngqo kwi-SolidWorks, iiflegi ezinokubakho iingxabano ezisayilwayo ngaphambi kokwenziwa komngundo, kwaye babelane ngedatha yokuhlola ekrwada-hayi nje ukupasa okuluhlaza/obomvu/ukungaphumeleli kwezitampu.
Ulawulo oluthembekileyo lokuhamba kweshishini aluqalisi kufakelo. Iqala apho i-alloy idibana nenjongo yoyilo-kwaye ihlala apho ngemijikelo ye-10,000, iminyaka engama-20, kunye namaxesha amathathu okugcina. Ukuba iprojekthi yakho elandelayo ifuna ukuqina komgangatho weStellite ngaphandle kokubeka esichengeni ukuthembeka komda, khangela khangela ivalve Umzi-mveliso weStellite ephatha i-metallurgy, machining, ne-metrology njengenkqubo enye eqhubekayo—kungekhona amasebe amathathu ahlukeneyo. Ayibobunewunewu obo. Yeyona siseko seenkqubo ezibalulekileyo zobuthunywa.
