Xa iinjineli zicacisa impompo kunye ne-valve castings, azikho nje ii-odolo zamacandelo-zibophelela kwingqibelelo yenkqubo phantsi koxinzelelo, ubushushu kunye noxinzelelo lwebhayisekile. Isiphene esinye sokuphosa kwipiston pump cylinder yendlu sinokubangela ukusilela kokuphola kwiiyunithi zamandla oxinzelelo lwehydraulic. Isitulo sevalve esingahambi kakuhle kwindawo yolawulo lweoyile sisenokuthetha ixesha lokuphumla elingacwangciswanga elixabisa i-$50,000/yure. Kungenxa yoko le nto ukhetho umzi-mveliso wempompo kunye nevalve ayikho malunga nexabiso okanye ixesha lokukhokela yedwa. Imalunga nokuhambelana kwe-metallurgical, ukuthotyelwa kwe-GD&T kwi-± 0.02 mm, kunye nokuqeqeshwa kwenkqubo ephatha yonke indawo yobushushu njengecandelo elibalulekileyo lokubhabha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngokusuka kule nyaniso—kungekhona njengesiseko sokwenziwa ngabenzi, kodwa njengeqabane elichanekileyo leenkqubo zokulawula ulwelo olubalulekileyo kubuthunywa. Siye sabona abathengi bebuya kunye ne-cobalt-alloy nozzles eziqhekekileyo emva kweeyure ze-420 zenkonzo ye-slurry yesantya esiphezulu. Unobangela weengcambu? Ulwakhiwo olungahambelaniyo lweenkozo ukusuka ekupholiseni okungalinganiyo kwizibumba zesanti. Impendulo yethu yayingekho nje ukuphosa kwakhona-yayikuhlengahlengisa inkqubo ye-gating, yongeza imephu yexesha langempela le-thermal ngexesha lokuqinisa, kunye nokuqinisekisa i-microstructure nge-SEM / EDS kwi-batch nganye ye-AMS 5387. Yiyo indlela "ukuphosa ngokuchanekileyo" ukusuka kwibango lencwadana ukuya kwindlela yokuziphatha eqinisekisiweyo.
Izigqibo ezithathu zobuchwephesha zahlula impompo ethembekileyo kunye nevalvu ephosa kwiindawo zentengiso-kwaye iQINGDAO QIANGSENYUAN izifaka zontathu kwimisebenzi yemihla ngemihla:
- Ukulandeleka kwezinto kuqala ngaphambi kokunyibilika. Sifumana i-cobalt-nickel alloys kuphela kubaboneleli abaqinisekisiweyo kwi-ASTM B575 kunye ne-AMS 5719, kunye neengxelo ezipheleleyo zovavanyo lokugaya. I-ingot nganye ithwala i-ID yokushisa ekhethekileyo ye-laser-ephawulwe kwipatheni yokuphosa-elandelekayo kumandla obunzima, ukuqina, kunye nedatha ye-intergranular corrosion resistance.
- Umatshini ayikokucoca ngasemva-yi-inshurensi elinganayo. Iziseko zempompo ezifakwe kwisanti zihlala zifuna ±0.15 mm umcaba kwisithuba seemitha ezi-1.2. Sisebenza ngomatshini iindawo ezibalulekileyo zokutywina *emva* konyango lobushushu lokunciphisa uxinzelelo-hayi ngaphambili-ukutshixa uzinzo. Amaziko ethu e-CNC ane-5-axis asebenzisa inkqubo yokuhlola ukuqinisekisa ubunzulu bebhore ngaphakathi kwe-0.008 mm phambi kojiko lokugqibela olunzima.
- Ukuqinisekiswa okusebenzayo kuthatha indawo yoluhlu lokutshekisha olune-dimensional. Ukukhutshwa kwevalve yoxinzelelo kudlula ukuhlolwa kweCMM-kodwa ngaba itywina kwi-6,000 psi kunye nokuvezwa kwe-H₂S? Sivavanya yonke imveliso ye-API 6D protocol: ukuqhuma kwe-hydrostatic, ukuphuma kwembacu, kunye nokunyamezela umjikelo ukuya kuthi ga kwi-10,000 yemijikelo. Amalungu angahambelaniyo akaphinda asebenze. Baqalisa inkqubo yophicotho olupheleleyo.
Abanye banokuxoxa ukuba ukuphoswa kotyalo-mali kuzisa ukugqitywa okungcono komphezulu kunokuphosa isanti-ke kutheni ukhetha isanti kwizindlu ezinkulu zempompo? Ngenxa yokuba izibungu zesanti ziphatha i-800 kg+ ubunzima ngaphandle kokuphazamiseka, kwaye iibhokisi zethu ezilawulwayo zokupholisa zihambisa ukufana kwe-microstructural efanayo. Silinganise ukuqina kobunzima kuwo wonke amacandelo eludongeni angama-320 mm kwi-±3 HB nje—ngaphakathi kweebhanti zokunyamezelana ngokuqhelekileyo ebekelwe izindlu zeinjini yomoya. Urhwebo alukho umgangatho; kukwaleka. Ukuqhuba umthamo ophakathi (i-50-500 pcs / ngonyaka) yensimbi eyinkimbinkimbi okanye i-stainless steel castings, ukuchithwa kwesanti kunye nokugqiba i-CNC kunika i-22% yexabiso eliphantsi lilonke ngeyure yokusebenza kuneendlela zokutshala imali-ngaphandle kokuncama ubomi bokukhathala.
Yintoni abathengi abasibuza yona-ngokuphindaphindiweyo-ayisiyiyo "Ngaba ungayenza?" Ngu "Ngaba ungayenza * isebenze * - kwisicelo sam, kwishedyuli yam, ngezinto ezothusayo?" Oko kuthetha ukuphonononga ii-callouts ze-GD&T kwimizobo yemigibe yokwenziwa: ukucacisa i-Rz endaweni ye-Ra yokutywinwa komphezulu, ukuphawula iingozi zedatum shift kwi-multi-setup machining, okanye ukucebisa ialloyi ye-T800 ngaphezulu kwe-316SS yomgangatho xa umngcipheko wokugoba i-chloride udlula i-12 ppm. Sibuyisela iiPDF ezichaziweyo kwisithuba seeyure ezingama-48-hayi "amanqaku aqinisekisiweyo aqinisekisiweyo", kodwa impendulo esebenzayo efana "Hambisa i-datum B kubuso obunomatshini ukunqanda impazamo eyongezelekayo kwiiseti ezintathu." Le yintsebenziswano yobunjineli, hayi ukusetyenzwa kweeodolo.
Ukujonga phambili, imfuno yezisombululo ze-hybrid casting-machining zikhawuleza-kungekhona nje iimpompo kunye neevalve, kodwa kwiinkqubo zokunyanzeliswa kwe-hydrogen elandelayo apho i-cobalt-based alloys kufuneka imelane noxinzelelo lwe-MPa eyi-100 kunye ne-40 ° C embrittlement. I-QINGDAO QIANGSENYUAN yandisa umthamo wayo wokunyibilika we-vacuum induction kunye nokuphuhlisa izixhobo zokulinganisa ukuqina okukhokelwa yi-AI ukuqikelela ukukrazula okushushu kwiijiyometri ezintsonkothileyo zodonga. Umda wesiqinisekiso uyakhula nawo: I-ASME BPVC yeCandelo le-VIII Div 2 imvume iyaqhubeka, kwaye ulungelelwaniso lwe-ISO 13485 luqhubela phambili kumacandelo okuphatha ulwelo lodidi lwezonyango.
Ukuba iprojekthi yakho elandelayo ibandakanya iivalvu zoxinzelelo, i-piston pump cylinder housings, okanye i-engineered winch shafts-kwaye ufuna i-dimensional ngokuqinisekileyo, ingqibelelo yezinto eziphathekayo, kunye nokuqeqeshwa kokunikezelwa-qala ngokuphononongwa komzobo. Hayi isicelo sekowuti. Ingxoxo yobugcisa. Ngenxa yokuba eyona mpompo inamandla kunye nevalve castings ayiphoswanga esantini okanye ngeceramic. Benziwa ngobungqongqo bobunjineli ekwabelwana ngaso.
