Xa iinjineli zicacisa iinxalenye zentsimbi yomxhuzulane, azikho izinto zokuodola kuphela-zibophelela kwimfezeko yolwakhiwo phantsi koxinzelelo, ukuzinza komda kwimijikelo yobushushu, kunye nokunganyangeki kwexesha elide kwiindawo ezinobutshaba. Yiyo loo nto ukhetha okulungileyo umxhuzulane ophose iinxalenye zentsimbi umzi-mveliso ayisiyobhokisi yokukhangela yokuthenga-sisigqibo senqanaba lenkqubo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siye sabona indlela izenzo zokuphosa ezingalungelelanisiweyo eziphazamisa ixesha logunyaziso lwempompo, indlela efihlakeleyo yegraphite morphology etshintsha ngayo ukutywinwa kwesihlalo sevalve, kunye nendlela engahambelaniyo ye-shakeout yexesha ekwazisa ngayo uxinzelelo oluncinci kwizindlu zecylinder. Ezi ayizizo iinkxalabo zethiyori. Ziindlela zokungaphumeleli eziqinisekisiweyo esizixilonga rhoqo ngeveki.
Kutheni iGravity Casting isaphumelela kumacandelo entsimbi abalulekileyo
I-Centrifugal okanye i-die casting inokubonelela ngonyamezelo olungqongqo kwiijiyometries ezilula-kodwa ukujulwa komxhuzulane kuzisa eyona nto ifunekayo kubuthunywa be-hydraulic kunye ne-oyile kunye negesi: isikhokelo sokuqina esilawulwayo, imbuyekezo eqikelelwayo yokucutheka, kunye nokungaguquguquki kwesinyithi kuwo wonke amacandelo ashinyeneyo. Sihlala siphosa izindlu zepiston pump cylinder ukuya kuthi ga kwi-420 mm ubukhulu bodonga kunye ne-ASTM A48 Class 350 yamandla okuqina-kwaye sibambe ukunyamezela kwe-GD&T ye-± 0.15 mm ebusweni obubalulekileyo. Njani? Ngokudibanisa i-sand mold simulation (usebenzisa i-MAGMAsoft) kunye ne-real-time monitoring thermocouple kwiindawo ezintathu zobunzulu ngexesha lokuthulula. Oku akuyontelekelelo. Lulawulo lwenkqubo oluqhutywa yifiziksi.
Isiseko sethu sisebenzisa isanti ye-silica ebuyisiweyo edityaniswe ne-furan resin-ingqinwe kwi-ISO 22988 yokuziphatha kokubola kwe-binder. Kodwa ukhetho lwezinto eziphathekayo kuphela aluqinisekisi ukusebenza. Siye saqaphela ukuba amazinga okupholisa angalawulekiyo angaphantsi kwe-120 ° C / iyure abangela uhlobo lwe-D lwe-graphite ukubunjwa kwi-ASTM A278 yeBanga le-65-45-12 i-ductile iron-ehambelana ngokuthe ngqo kwi-23% ephantsi kokukhathala ubomi kwi-winch center shaft rollers. Ke sinyanzelisa iiprothokholi zokupholisa zomoya ngenkani zilinganiswe ngokwenxalenye yobunzima kunye nemodyuli yecandelo. Ibhetshi nganye ithwala ukulandeleka okupheleleyo: inani lokunyibilika, ubushushu obuthululwayo, ukuthambeka kwegophe lokupholisa, kunye nokuqinisekiswa kokuqina kokugqibela.
Apho uMatshini adibana khona nokuCalwa-kwaye kutheni ukudityaniswa okuthe nkqo kubalulekile
Ukuphosa umxhuzulane kubeka isiseko. Umatshini ochanekileyo unikezela ngemigangatho esebenzayo. Ukwahlula ezi nkqubo kumema umngcipheko. Silandele i-68% ye-dimensional nonconformities kwi-third party machined castings ukuya kwi-datum shift phakathi kwe-casting kunye nokuseta kwe-CNC-ingakumbi kwiziseko zempompo ze-asymmetrical ezineenqwelomoya ezininzi zokunyuka. Isisombululo sethu? Ulawulo lokuhamba komsebenzi owenziwe ngomatshini: umqhubi ofanayo weCMM uqinisekisa imilinganiselo ye-cast-cast * kunye * nejometri egqityiweyo; into efanayo ibeka izigaba zombini; Ilebhu efanayo ye-metrology iqinisekisa ngaphambi nasemva konyango lobushushu.
Oku kudityaniswa kwenza iimpawu ezifana ne-AMS 5387 i-cobalt alloy ifake i-press-fitted kwi-cast iron housings-apho ukungafani kokwandisa kwe-thermal kufuneka kuhlaziywe ukuya kwi-± 0.002 mm ukuphazamiseka. Okanye imilomo esekelwe kwi-T800 ene-0.05 mm yokunyamezela ubukhulu bodonga, enziwe ngokuthe ngqo ukusuka kwi-blank blanks ngaphandle kokuphazamiseka-ukunciphisa uxinzelelo. Asilukhupheli ngaphandle unyango lobushushu. Izixhobo zethu zokufunxa ziqhuba imijikelo eqinisekisiweyo nge-AMS 2750E nganye, ngokugawulwa kwe-pyrometer ngokuqhubekayo. Ngenxa yokuba xa i-valve yakho yoxinzelelo isebenza kwi-bar ye-415, "ivale ngokwaneleyo" ayikho inketho.
Ijongeka Njani Ukuqinisekiswa Kwehlabathi Lokwenyani
Abathengi bayabuza: "Ubonisa njani ukuthembeka?" Hayi ngezatifikethi zodwa-kodwa ngedatha yovavanyo. Iiplagi zethu ze-cobalt-nickel alloy zifaka uvavanyo lokukhukuliseka komjikelo we-10,000 kwi-3.5% ye-NaCl brine kwi-85 ° C, ukulinganisa inkonzo yempompo ye-offshore. Iziphumo zibonisa <1.2 μm/unyaka ukulahlekelwa kwezinto-ngokuchasene noshishino-umyinge we-4.7 μm / ngonyaka. Kwi-roller ye-winch yemoto yobunjineli, siqinisekisa ingqibelelo yomhlaba sisebenzisa uhlalutyo lwengxolo ye-Barkhausen ukufumanisa ukutshisa okungaphantsi komhlaba okungabonakaliyo ekuhlolweni kwe-optical. Kwaye yonke into ethunyelwayo ibandakanya ii-certs zemathiriyeli ezigcweleyo: Iingxelo ze-OES spectrography, i-tensile test curves, kunye ne-microstructure photos annotated per ASTM E112.
Sabelana ngezifundo esiziphumelele nzima. Umzekelo: iibhetshi zangaphambili zeeflange zempompo ezingekho mgangathweni zibonise ukuvuza kwegasket kwangaphambi kwexesha. Unobangela weengcambu? Ukukhupha umngundo akwanelanga ukugalelwa koxinzelelo oluphezulu. Isisombululo? Ukuqulunqwa kwakhona kweeprinta eziphambili kunye ne-0.3 mm ye-radial vents-iqinisekiswe yi-X-ray CT scan. Ngoku ezo flange zifezekisa ukuvuza kwe-zero kwi-1.8 × uxinzelelo olulinganisiweyo. Lowo ngumahluko phakathi komthengisi kunye neqabane.
Ukukhetha Umzi-mveliso Wakho Wezixhobo Zentsimbi—Ngaphaya Kwencwadana
Ukuba isicelo sakho sifuna i-ASTM A ductile iron ene-spheroidization>92%, okanye idinga iminxeba ye-GD&T yendawo yokwenyani kwiipateni ezinemingxuma eli-12, qinisekisa ezi zinto zintathu phambi kokuba usayine:
- Ngaba bangabanini bomdlalo wabo wokusa kunye noomatshini? Amanyathelo aphuma ngaphandle atshabalalisa ukulandeleka kwaye angenise umngcipheko weshedyuli.
- Ngaba banokukubonisa iingxelo zeCMM zokwenyani-hayi nje ukudlula / izitampu zokusilela? Jonga amaxabiso okutenxa ekrwada, hayi nje ii-checkmark eziluhlaza.
- Ngaba bayapapasha amaxesha abo ovavanyo lwesanti? Isanti ebuyisiweyo ifuna ukufuma kwemihla ngemihla kunye nokuhlolwa kokungena kwi-ISO 10083 nganye.
