Xa indlu yakho yempompo ye-hydraulic iqhekeka kwi-450 ° C, okanye i-cobalt alloy nozzle isilela phantsi komothuko we-cyclic thermal, "indawo yokushisa ephezulu ekwazi ukumelana nobushushu" iyayeka ukuba ligama lokukhangela-iba ngumhla wokugqibela. Siyibonile kwiikhontrakthi zenkonzo ye-oyile yaseMntla Merika, kwi-European offshore valve retrofits, kunye nakwizityalo zokukhupha ityuwa ekuMazantsi mpuma eAsia: izinto eziphuma eshelufini ziyaboleka. Into ebambekayo ayikona nje ukumelana nobushushu-kukuhambelana kwesinyithi, ukuzinza komda emva kokuhamba ngebhayisikile yobushushu, kunye nokunyamezelana kwe-zero kulwahlulo lwe-microstructural. Yiyo loo nto iinjineli zicacisa-hayi nje izixhobo-kodwa umzi-mveliso weendawo ezixhathisa ubushushu obuphezulu emva kwabo.
Ukusebenza kwehlabathi lokwenyani kuqala kwakudala ngaphambi komatshini. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke inxalenye ye-cobalt ye-cobalt ye-AMS 5387 iqala ngokulandelelwa kwezinto ezibonakalayo eziqinisekisiweyo-ukuhla ukuya kwinani lobushushu kunye nengxelo yovavanyo lokusila. Asizamkeli izatifikethi "ezihambelanayo"; siqinisekisa ukuhanjiswa kobungakanani beenkozo kwiibhilithi ezingenayo zisebenzisa i-ASTM E112 protocol. Ngoba? Ngenxa yokuba ukuphambuka kwe-5% kwi-carbide dispersion kunokunciphisa ubomi benkonzo nge-60% kwiindibano zempompo eziphezulu. Kwiprojekthi yamva nje yemoto yobunjineli yaseJamani i-OEM, uhlalutyo lwethu lwangaphakathi lwendlu lubambe umxholo we-nickel osecaleni kwibhetshi ye-T800 yealloy-ngaphambi kokuphosa. Oko kufunyaniswa kuthintele i-120 engaphumeleliyo kwi-shaft rollers kwiziko kwiinkqubo ze-winch ezisebenza kwi-520 ° C yobushushu bomhlaba kunye ne-120 MPa yomthwalo ophakathi.
Ukudityaniswa ngokuthe nkqo akulogama apha-yindlela esilawula ngayo eyona nto ibalulekileyo: indlela yokutshintsha isigaba ngexesha lokupholisa. Izindlu zentsimbi ezifakwe kwisanti kwiimpompo zepiston ziphantsi komjikelo olawulwayo we-ramp-down ngaphakathi kwiziko lethu lokunyanga ubushushu-engakhutshelwanga ngaphandle. Oko kuthetha ukubala okuqikelelweyo kwegraphite nodule (ASTM A247 Class 3), ubulukhuni obufanayo (220–260 HBW), kwaye akukho lushiyeko olubangelwa luxinzelelo lwewarpage emva kokugqiba iCNC. Okwangoku, i-cobalt alloy nozzles ye-investment-cast-cast ifumana i-HIP'd (i-hot isostatic pressing) ngokukhawuleza i-post-casting ukuphelisa i-microporosity-ebaluleke kakhulu xa ubukhulu bodonga buhla ngaphantsi kwe-2.3 mm kunye noxinzelelo lokusebenza ludlula ibha ye-350. Abathengi bayabuza: “Ungakwazi ukubamba ±0.015 mm kwindlu yesilinda yedayamitha eyi-320 mm emva kweeyure ezi-3 kuma-480°C?” Ewe-kuba siqinisekisa ukukhula kwe-thermal coefficients kwisampulu yejometri phambi kwemveliso epheleleyo, hayi emva.
Abanye bacinga ukuba amandla obushushu aphezulu avela kuphela kwi-alloys engaqhelekanga. Kodwa sibona ukusilela okungaphezulu kokwenziwa kakubi kwe-GD&T kunekhemistri engalunganga. Umzimba wevalve yoxinzelelo unokusebenzisa intsimbi esemgangathweni ye-F22-kodwa ukuba isihlalo saso sokutywina asinanto yokulawula indawo yokwenyani xa sithelekisa nesiqu, ukuvuza kwamatye kwi-300 ° C. Yiyo loo nto uhlolo lwethu lungaqhutywa luluhlu. Yonke into ebalulekileyo ifumana ukuqinisekiswa kwe-CMM ngokuchasene nemodeli ye-CAD yokuqala-kungekhona nje imilinganiselo ye-nominal-kunye ne-optical profilometry ebusweni bokutywina ukuze kuqinisekiswe i-Ra ≤ 0.4 µm emva kokugqithisa. Kwizinto ezingezizo eziqhelekileyo ze-T800, siqhuba ukuqinisekiswa komjikelezo we-thermal: imijikelezo emithathu epheleleyo ukusuka kwi-ambient ukuya kwi-550 ° C, ngoko uvavanyo olusebenzayo kuxinzelelo oluphezulu. Akukho ngaphandle. Akukho kurhoxiswa.
Ukuba ukhangela amaqabane efektri amelana nobushushu obuphezulu namhlanje, jonga ngaphaya kweziqinisekiso eludongeni. Buza: Ingaba ngabanini bonyango lwabo lobushushu? Ngaba banokukubonisa iifoto ze-microstructure kwi-AMS 5387 yenyanga ephelileyo? Ngaba baya kuphonononga kwakhona ii-callouts zakho ze-GD&T ngaphambi kokuba ucaphule-kunye neflegi apho ukunyamezelana okungqongqo kwongeza iindleko kodwa akukho msebenzi? QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngolu hlobo kuba ukuthembeka akuhanjiswa kwisikhongozeli sokuthumela. Yakhelwe kwinani ngalinye lobushushu, yonke indlela yesixhobo, yonke irekhodi yokuhlola. Ngexesha elizayo xa inkqubo yakho ishushu, amalungu akho akufuneki aphile-kufuneka enze. Oko kuqala ngokukhetha ukuba ngubani olawula izinto eziguquguqukayo ezibalulekileyo.
