Iyo pompe hydraulic yananiwe mu ruganda rwamavuta rwo hanze - cyangwa valve ya piston ifata imbere muri pompe yumuvuduko mwinshi - intandaro ntisanzwe. Ni kwambara. Kandi ntabwo ari imyambarire iyo ari yo yose: ni mikoro-mikoro, guhonyora, no gutwarwa nisuri munsi yumuzigo wikirenga urenga MPa 300. Twabibonye ku mbuga za Noruveje y'Amajyaruguru no mu majyepfo y'uburasirazuba bwa Aziya amato yo gucukura-aho kunanirwa kwa Stellite imwe ihagarika ibikorwa mu masaha 48+. Niyo mpamvu abajenjeri batabaza ngo "Nibihe bihendutse cyane?" Barabaza bati: "Ninde ushobora gutanga AMS 5387 yo mu rwego rwa cobalt alloy amaboko hamwe na ± 0,015 mm kwihanganira kuzenguruka, gukurikiranwa n’ubushyuhe bwuzuye, hamwe nubuzima bwagaragaye burenze amasaha 12.000 yo gukora?"
Kuki "Uruganda rukora ibyuma" ntabwo ari ijambo ryishakisha gusa-ni akayunguruzo
"Uruganda rwa satelite" rwerekana ibimenyetso birenze ubushobozi bwo gukora. Nibisobanuro bigufi kubijyanye na disipuline, gutunganya neza, no kumenya-gutsindwa. Amavuta ya satelite-cyane cyane icyogajuru 6 (AMS 5387) na T800 - ntabwo akozwe nkibyuma bitagira umwanda. Matrix yabo ya cobalt-chromium-tungsten irwanya ibikoresho byo gutema, akazi-gakomeye, kandi gasaba ituze ryumuriro mugihe cyo gusya. Nukuri Uruganda rukora amaboko igomba kugenzura ibintu bitatu bidashobora kuganirwaho: icyemezo cyibikoresho fatizo (raporo yikizamini cyurusyo kuri ASTM F75 cyangwa AMS 5732), kugabanya imihangayiko nyuma yo gutunganywa kugirango wirinde kugabanuka, no kugenzura ubusugire bwubutaka - ntabwo ari agaciro ka Ra gusa, ahubwo ni microcrack yo munsi y'ubutaka ikoresheje ibizamini bya fluorescent.
Twagenzuye abatanga ibicuruzwa barenga 30 basaba ubuhanga bwa Stellite. Kimwe cya kabiri ntigishobora kubyara indangamuntu isubirwamo munsi ya Ra 0.4 µm kuri bore ya mm 120. Imwe yatanzweho amaboko hamwe na 0,08 mm hanze-yuzuye-yemewe kumatara yumuvuduko muke, ibiza kuri pompe piston. Itandukaniro riri muburyo bwo guhuza: guteranya ingano yimiterere, kugenzura ibikoresho bya CNC kubikoresho bya cobalt, hamwe no kugenzura CMM kuri buri cyiciro - ntabwo ari ubugenzuzi bwa nyuma.
Ubushobozi bune butandukanya ibikoresho byujuje ibyangombwa bya Stellite hamwe namaduka rusange yicyuma
Uruganda nyarwo rwa Satelite rukora ruhurira kumasomo atatu: metallurgie, gutunganya neza, no kwemeza imikorere. Dore ibyo tugenzura mbere yo kwemeza uwabitanze:
- Ibikoresho bikurikirana kugeza kuri ingot-Ntabwo ari imibare gusa, ahubwo raporo yimiti yemewe ihuye na AMS 5387 (C: 0.9-1.4%, Cr: 27-31%, W: 3.5-5.5%, Co balance)
- Multi-axis CNC ubushobozi hamwe nibikoresho bikomeye—Nta musarani usanzwe; dukeneye Y-axis igikoresho kizima hamwe na coolant-binyuze muri spindles kugirango dukemure chip evacuation no kugoreka ubushyuhe
- Kwishyira hamwe- gukemura annealing kuri 1175 ° C ± 10 ° C bikurikirwa no gukonjesha ikirere byihuse, bigenzurwa no gushushanya amakarita yambukiranya ibice (HRC 38-44, imyenda iri muri point 2)
- Ibikorwa remezo byo kugerageza-Ntabwo ari igenzura gusa, ahubwo ni igeragezwa rya serivisi: amasaha 500 yo kugerageza kugerageza guhangana na 420SS ikarishye munsi ya 200 MPa hydraulic umutwaro
Hatariho bane, urimo kugura ibice-ntabwo ari ibyiringiro byimikorere. Twabonye amaboko atambuka CMM ariko birananirana nyuma yinzinguzingo 800 kuko guhangayika bisigaye byateje micro-gusudira kuri interineti. Niyo mpamvu QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikubiyemo metallurgiste mugutegura umusaruro - ntabwo ari abajyanama, ahubwo nka banyiri inzira.
Igiciro cyihishe cya "off-the-shelf" amaboko ya satelite-nuburyo geometrie yihariye yongerera agaciro
Abaguzi bamwe bibwira ko amaboko ya Stellite yagurishijwe. Ntabwo aribyo. Ibipimo bisanzwe bya OD / ID birengagiza ibintu byihariye bya sisitemu: kwaguka k'ubushyuhe budahuye hagati y'intoki n'inzu, gupakira asimmetrike mu bishushanyo mbonera bya pompe, cyangwa guhinda umushyitsi guterwa no gufatira hamwe. Twigeze gusimbuza amaboko rusange muri pompe yubucukuzi bwamabuye y'agaciro hamwe na variant yabigenewe irimo interineti ikomatanyirijwe hamwe na radiyo ya firimu. Igisubizo: 3.2 life igihe kirekire cyumurimo wa serivise, zeru zeru zidatemba, no gukuraho igihe cyateganijwe. Igiciro cya "gakondo" cyari hejuru ya 18%. ROI? Amadolari 217.000 yazigamye buri mwaka mu mirimo, ibice by'ibicuruzwa, no gutakaza umusaruro.
Inganda nyazo za Satelite ntizigabanya gusa gucapa-zibaza imikorere. Iyo umukiriya atwoherereje igishushanyo cya GD&T, ikibazo cyacu cya mbere ntabwo "Turashobora kugikora?" Ni "Ni ubuhe buryo bubi bwo gutsindwa mu buryo bwo kwihanganira bukumira?" Iyo mitekerereze ihindura ikiganiro kuva ku giciro kuri buri giciro ku isaha yo gukora.
Aho ibisobanuro bihuye no kwizerwa-n'impamvu bitangira kera mbere yo gukata bwa mbere
Uruganda rwa Satelite rworoshye rutera ikizere atari igice cyarangiye, ahubwo rugenzurwa hejuru. Kuri TEKINOLOGIYA YA QINGDAO QIANGSENYUAN, kwakira ibintu bitangirana no gusesengura ibintu kuri buri kabari kobalt yinjira. Imashini ikoresha ISO 2768-mK kwihanganira nkibanze-ntabwo ari intego, ariko nkibisanzwe. Buri ntoki ikorerwa 100% ultrasonic yipimisha imbere, hanyuma optique profilometrie yo gushushanya ikarita yubutaka hejuru ya 5-µm. Ibipfunyika byanyuma birimo ibyiciro byihariye bikubiyemo chimie, ubukana, amakuru yikigereranyo, hamwe nibizamini bidasenya-bikurikirana gushonga kwambere.
Ibi ntabwo birenze ubuhanga. Ni kugabanya ingaruka. Kuberako iyo gusaba kwawe gukora kuri 15,000 psi hamwe na flux yuzuye umusenyi wuzuye, ntamahirwe ya kabiri. Ukeneye a Uruganda rukora amaboko ifata buri kintu cyose nkibikorwa byingenzi-sibyo kuko ibivuga kurubuga, ariko kuberako inzira zabo zidasiga umwanya wo gutekereza. Ngiyo igipimo dufite-kandi injeniyeri umwe arasaba cyane.
