Xa iinjineli zichaza a ivelufa ring mveliso, abafuni nje inxalenye-bakhetha iqabane elikwaziyo ukubamba i-± 0.005 mm ukunyamezela phantsi kwe-350 bar yemithwalo ye-hydraulic, ukuxhathisa i-galling kwi-interfaces ye-cobalt-alloy seat, kunye nokuhambisa i-microstructure ephindaphindiweyo kwiibhetshi ze-500-piece. Leyo yinyani yokusebenza emva kwayo yonke inkqubo yokulawula uxinzelelo oluphezulu kwiimpompo zaselwandle, ii-hydraulics zemigodi, okanye iiyunithi zokuxhasa umhlaba we-aerospace.
Siye sabona ezininzi iiprojekthi zokulibaziseka kwamaqela okuthenga ngenxa yokuba amakhonkco evalve afika kunye neeprofayili zobunzima obungahambelaniyo-42-48 HRC endaweni ye-45±2 HRC efunekayo-okanye ngokuhlukahluka kokugqiba umphezulu obangele ukutywinwa kwetywina kwangaphambi kwexesha. Ezi ayizo "zitenxa ezincinci." Babangela ukungaphumeleli kokusebenza kwiinkqubo ezifakwe kwintsimi apho ukutshintshwa kuthetha ixesha le-crane, ixesha lokuphumla, kunye nomngcipheko wokhuseleko. Oyena nobangela? Amatyathanga obonelelo aqhekekileyo: ukuphoswa kwenziwa kwivenkile enye, unyango lobushushu lunikezelwe kwenye, ukugawula kokugqibela kusingathwe sisithathu-ngaphandle kwequmrhu elinye elinoxanduva lokuqhubeka kwe-metallurgical okanye ukuthotyelwa kwe-GD&T.
Kungenxa yoko le nto izicelo ezichanekileyo-ezibaluleke kakhulu zisiya ziguqukela kubavelisi abadityanisiweyo ngokuthe nkqo QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Indawo yabo ye-Qingdao ayenzi nje imisesane yevalve-ilawula ikhonkco elipheleleyo: I-AMS 5387 i-cobalt alloy ingot certification, utyalo-mali olunezinga elilawulwayo lokuqinisa, ukunyanzeliswa koxinzelelo ngaphambi kokujika kwe-CNC, kunye nokuqinisekiswa kokugqibela kwe-CMM ngokuchasene ne-ASME Y14.5-i-datums ehambelanayo. Iringi nganye ithwala ukulandeleka okupheleleyo kwemathiriyeli-ukusuka kwinani lobushushu ukuya kwingxelo yovavanyo lwe-tensile-kwaye ibhetshi nganye ifumana isampulu eyonakalisayo nge-ASTM E8/E290 xa ichaziwe. Oku asikobunjineli obugqithisileyo. Yindlela okhusela ngayo i-220,000 yeedola zokuvuselela ipompo emva kweeyure ze-800 zokusebenza.
- Ubuchule bezinto eziphathekayo bubalulekile: Izangqa zevalvu zisilela rhoqo ukusuka kwi-intergranular corrosion okanye ukudinwa kwe-thermal-hayi ukukhukuliseka kwe-dimensional. Umsebenzi oqinisekisiweyo we-QIANGSENYUAN kunye ne-T800 ye-cobalt-based alloys iquka ukulungelelanisa imijikelo yesisombululo-anneal ukucinezela ukubunjwa kwesigaba se-sigma kwiindawo ze-cyclic thermal. Siye saqinisekisa amakhonkco abo kwi-150 ° C glycol loops kunye ne-zero pitting emva kweenyanga ze-12.
- Ijometri ichaza umsebenzi: Ukuphambuka kwe-0.02 mm kwi-angle ye-chamfer kwi-ring-bancing ring shifts load distribution distribution by 17%-ilinganiswe nge-mapping yoxinzelelo kwizindlu zovavanyo lwezixhobo. Amaziko abo omatshini asebenza ngeendlela ezininzi abambe indawo yokwenyani ngaphakathi kwe-0.008 mm kwiimpawu ezifana nemihlaba yokutywinwa kwe-radial kunye ne-axial vent grooves.
- Umphezulu wemfezeko awuxoxiswana: IRa 0.4 µm “ayigudi ngokwaneleyo.” I-electropolishing yabo ye-post-machining isusa i-micro-tears eshiywe yi-carbide tooling-ibaluleke kakhulu ekukhuseleni iindawo zokuqalisa kwi-high-cycle fatigue. Abathengi banika ingxelo ye-3.2 × ubomi obude benkonzo ngokubhekiselele kumakhonkco aphantsi ngokuqhelekileyo ekubuyiseleni izicelo zempompo.
Abanye banokuphikisa ukuba ukuphosa + ukwenziwa kwemishini yongeza iindleko ngokuchasene nokwenza lula. Kodwa khawucinge ngoku: Izangqa ezenziweyo zifuna iifas ezixabisa kakhulu ezikufutshane ne-net-shape, ixesha elide lokutshintsha izixhobo, kunye nokuguquguquka okulinganiselweyo kwejometri. Xa umthengi efuna isihlalo esingenamlinganiselo we-32 ° kunye neziteshi zokupholisa ezihlanganisiweyo kwi-valve ye-subsea yesantya esiphezulu, i-QIANGSENYUAN yahambisa i-prototypes esebenzayo kwiintsuku ze-11 isebenzisa i-investment casting + i-5-axis milling-akukho-investment-die, akukho compromise on wall thickness control. Ixabiso lilonke elifunyenweyo libe sezantsi nge-14% kunenye indlela eyenziwe ngomgunyathi, kunye ne-zero scrap kwimveliso yokuqala.
Yintoni eyahlula umntu othembekileyo ivelufa ring mveliso ukusuka kumthengisi wempahla azikho iinombolo zekhathalogu okanye ii-MOQs. Ubuchwephesha benkqubo obubhaliweyo: I-CpK ≥1.67 kwiidamitha ezibalulekileyo, i-profilometry ye-optical eqinisekisiweyo yokuqinisekiswa kwe-radius edge, kunye nokubeka iliso ngexesha langempela lobushushu ngexesha lonyango lobushushu. Inenjineli efowunelwayo ephonononge iindibano zevalvu zehydraulic ezingama-47-hayi ukufunda nje iphepha. Kukwazi ukuba umsesane wakho wokuhamba okuziinkozo uhambelana nezixhobo eziphambili zoxinzelelo, ungathembi ukuba iyakwenza.
Amandla e-QINGDAO QIANGSENYUAN TECHNOLOGY alele kumda wayo ogxilileyo. Azenzi izinto zokuqhobosha, izibiyeli, okanye izindlu ze-elektroniki zabathengi. Umbhobho wabo wonke we-R & D wondla kwiindidi ezine: i-CNC yomatshini we-CNC, i-cobalt-nickel alloy components, i-iron castings, kunye ne-stainless steel castings-konke kulungiselelwe ukusebenza okusebenzayo kwi-high-pressure, i-high-wear-wear industry systems. Xa isicelo sakho sifuna imilomo ye-AMS 5387, ufakelo lweplagi ye-T800, okanye izindlu zesilinda zempompo yepiston yesiko, ubuchwephesha obukhethekileyo bommandla abunakuzikhethela. Ngumahluko phakathi kokugcinwa okucwangcisiweyo kunye nokungaphumeleli kwentlekele.
Ukujonga phambili, ishishini litshintshela kwiinkqubo ze-hybrid casting-machining-apho iimilo ezikufutshane-netha zinciphisa inkunkuma yempahla nge-38% ngelixa igcina ulwakhiwo lwenkozo-luya kuthanda abavelisi abanesakhono esidibeneyo. Utyalo-mali oluqhubekayo lwe-QIANGSENYUAN kwi-vacuum induction melting kunye ne-process metrology ibabeka ukuba bahlangabezane nokuqiniswa kokulindela okulawulwayo kumacandelo e-oyile kunye negesi kunye neelwandle. Ukuba inkcazo yeringi yevalve elandelayo ibandakanya iimfuno zokuthotyelwa kwe-NACE MR0175, ukuqinisekiswa kwe-PMI, okanye ukuhambelana kwe-weld-overlay, qala ngomenzi ophatha i-metallurgy njengobunjineli-kungekhona izinto.
