Iyo hydraulic valve yananiwe munsi yumuvuduko wa bar, 350, ni gake igishushanyo kirimo amakosa-ni Umupira wa valve umupira nintebe kwambara bitaringaniye, gucamo micro, cyangwa gutakaza ubunyangamugayo bwa metallurgji nyuma yizunguruka 8000 gusa. Twabibonye muri pompe ya pompe ya offshore, ubucukuzi bwa piston ya piston, hamwe na sisitemu yo gukoresha imiti myinshi cyane: intebe zicyuma zidafite ingese zangirika vuba. Cobalt ishingiye kuri Stellite alloys ntabwo. Ariko si bose Umupira wa valve umupira nu ruganda rwicara itanga ubukana buhoraho, gukwirakwiza karbide, cyangwa gusubiramo inshuro nyinshi mubice - cyane cyane iyo geometrie ikubiyemo imirongo ifunze kashe, bores eccentric bores, cyangwa intera-ikomeye.
Impamvu icyogajuru kitari "Icyuma gikomeye" -Ni Guhitamo Sisitemu-Urwego
Icyogajuru ntabwo ari ikintu kimwe. Numuryango-6, 12, 21, 25-hamwe na cobalt nkumugongo (40-65%), chromium yo kurwanya okiside, tungsten kubera ubukana bushyushye, na karubone kugirango ibe idashobora kwihanganira M7C3 na M.23C6 karbide. AMS 5387 (Spellite 6) ikubita HRC 38-44 ariko ikenera kuvura neza ubushyuhe kugirango wirinde ibice bya sigma. T800 alloy yongeramo nikel kugirango irwanye ubushyuhe bwumuriro-ingirakamaro mumashanyarazi afasha amavuta. Nyamara gukomera byonyine birayobya. Intebe ya satelite ifite ibice bya karbide bitatanye bikabije. Umupira ufite ibisigazwa bisigaye bisohoka kuri 120 ° C. Niyo mpamvu imikorere ikora iterwa nubushobozi butatu buhujwe: ubuhanga buvanze, kugenzura inzira, hamwe na disipulini ya metrologiya-ntabwo ari ibikoresho fatizo gusa.
Niki gitandukanya umupira wizewe wa Valve Ball nu ruganda rwicara mubindi
Twagenzuye abatanga ibicuruzwa barenga 30 basaba ubuhanga bwa Stellite. Benshi bananiwe kuri imwe mu ngingo eshatu:
- Ikinyuranyo cyibikoresho.
- Imashini yangiritse.
- Gufunga geometrie: Porogaramu ya CNC ifata neza neza. Ishoramari nyaryo rifite ± 0.3 mm yuburebure bwurukuta. Hatariho uburyo bwo guhuza n'imihindagurikire y'ikirere, umurongo wa nyuma wo gufunga utandukana> 0,05 mm uhereye ku zina-bihagije kugira ngo ugabanye ubuzima bwa kashe 60%.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Turafunga ibyo byuho. Ikigo cyacu cyujuje ISO gikora urunigi rwuzuye: vacuum-yashonze cobalt alloy ingots → gushora neza gushora → guhangayikishwa no gutunganya imashini → gutunganya karbide itunganya ubushyuhe → ibice bitanu byuzuye kurangiza → Kugenzura bande ya CMM. Buri ball ball ya Stellite itwara ID idasanzwe ihujwe nigiti cyayo gishonga, ikora raporo ya X-ray, hamwe nikarita yerekana ububi. Nta kibabi kibisi utabanje kugenzura ubukana bwa Rockwell C muri zone eshatu - kandi nta mato yintebe adafite ibizamini bya helium kuri 1.5 × igitutu cyakazi.
Imikorere-Isi Yukuri: Aho Precision Ihurira Gusaba
Umukiriya umwe wo mu nyanja y'Amajyaruguru yasimbuye umunywanyi wa Stellite 21 muri pompe yicyondo nyuma yamasaha 4.200 yumurimo. Gutobora Cavitation byari byarenze igice cyo munsi. Bahindukiye ku cyicaro cyacu cya AMS 5387 - geometrie imwe, inzu imwe - ariko hamwe n'umwanya wa karbide ukabije (upimye kuri SEM), umwuka wa ogisijeni wo hasi (<120 ppm), hamwe na nitride ikwirakwizwa nyuma yo gutunganya. Igisubizo: Amasaha 14.700 mbere yo kubungabunga gahunda. Ntabwo ari ukubera ko "byari bikomeye," ariko kubera ko microstructure yarwanyije ibice byombi byangiza * na * imyuka yinzibacyuho.
Urundi rubanza: uruganda rukora imiti yo mu majyepfo y’iburasirazuba bwa Aziya rwakeneraga imipira ya T800 idasanzwe kugirango ikoreshwe na diafragm metering valve ikora aside ya sulfurike 98% kuri 85 ° C. Igikoresho gisanzwe cya 6 cyangiritse kuri stem interface. Twongeye guhindura umupira hamwe na T800 ikwirakwizwa hejuru ya 17-4PH - twakorewe muburyo bumwe kugirango dukureho galvanic. Igice cyatsinze amasaha 1.000 ASTM G28A kwipimisha kwibiza hamwe no gutakaza ibiro zero. Ibi ntibyari hanze. Byari metometurjiya itwarwa na geometrie.
Guhitamo icyogajuru cya Valve Umupira nu ruganda rwicara - Baza ibi bibazo
Mbere yo gushyira umukono kuri NDA, baza uwaguhaye isoko:
- Urashobora gusangira raporo yerekana amashusho ya AMS 5387-yerekana urwego W, C, na Si urwego ntarengwa?
- Wapima ibice bya karbide (ukoresheje isesengura ryamashusho) kuri buri kintu - cyangwa gukomera gusa?
- Nigute ushobora kwishyura indinganizo yo guta muri gahunda yawe ya CNC? Ukoresha CT-scan amakuru kugirango uhindure inzira yinzira?
- Ni ubuhe buryo ntarengwa bwemewe bwo hejuru (Ra) ku kashe-kandi nigute wabigenzura neza, atari stylus gusa?
- Urashobora gutanga ibisobanuro byuzuye kugeza kuri numero ya electrode ikoreshwa muri vacuum arc remelting?
Niba ibisubizo bidasobanutse, byatinze, cyangwa ibyerekezo rusange aho kuba igishushanyo cyawe cya GD&T guhamagarwa-genda. Ibikoresho bya satelite ntabwo ari ibicuruzwa. Nibikorwa bya sisitemu ikomeye aho ikosa rya 0.01 mm rigura igihe, ntabwo ari amadorari.
Kuri ba injeniyeri bagaragaza imikorere-ikomeye yo gufunga ahantu habi ,. Umupira wa valve umupira nu ruganda rwicara uhitamo ugomba gufata metallurgie, gutunganya, na metrologiya nka disipuline itandukanijwe-ntabwo ari intambwe zikurikiranye. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka uku kwishyira hamwe mubikorwa byayo buri munsi. Icyibandwaho cyacyo gikomeje kuba gito: gukemura impuzu, kwangirika, no kunanirwa kunanirwa mukugenzura ubutumwa bukomeye-butangirira kubibaho aho icyuma gihura nicyuma, ukwezi nyuma yikiziga, igitutu nyuma yigitutu. Igihe gikurikira valve yananiwe imburagihe, reba kera ibimenyetso. Suzuma ikwirakwizwa rya karbide. Aho niho hatangirira igihe kirekire.
