Iyo ba injeniyeri bagaragaje uruganda rukora ibyuma bishora uruganda rukora uruganda ibisubizo, ntabwo bagura ibice-birinda umutekano muke munsi yumukino wo gusiganwa ku magare, microstructural guhuza ibice 500, hamwe no kwihanganira zeru kubitera imbaraga mumibiri yumuvuduko mwinshi. Twabonye imishinga myinshi yatinze kubatanga isoko bafata guta ishoramari nkigikorwa kimwe-cyuzuye-cyane cyane hamwe nicyuma cyumuhondo nudukoko, aho igenzura rihwanye na karubone, igipimo cy’ibicu kibanziriza ubushyuhe, hamwe n’imicungire y’ikime mu kubaka ibishishwa byerekana mu buryo butaziguye imashini n’ubuzima bw'umunaniro.
Kuki Gutera Icyuma Bisaba Kurenza Urufatiro
Gutera ibyuma ntabwo "byoroshye guta" gusa kuko bitemba neza. Imiterere ya grafite ya morphite - ihindagurika mucyuma cyijimye, nodules mu ductile - isubiza cyane umuvuduko ukonje, igihe cyo gutera, ndetse nubushuhe bw’ibidukikije mugihe cyo guteranya ibishashara. Ku kigo cyacu cyujuje ISO muri Qingdao, dufata buri kintu nkikigeragezo cya metallurgjique: ibyemezo byibikoresho byagenzuwe mbere yo kuvanga, itanura ryashushe ryakurikiranwe na spekrometrike nyayo, hamwe nibishishwa byokeje bitetse kuri 1100 ° C hamwe niminota 30 yo gutura - sibyo kuko ibipimo byabivuze, ariko kubera ko twapimye kugabanuka kwa 22% muminota 1.050.
Twatanze amazu arenga 470 yububiko bwa sisitemu ya hydraulic ikorera kuri bar 420-ntanumwe watsinzwe muri serivisi. Kubera iki? Kuberako ntiduhagarara kuri ASTM A536 cyangwa GB / T 1348.Twemeza nodularity dukoresheje isesengura ryamashusho kuri buri cyiciro cya gatatu, dukoresha utubari tensile duhereye kumasuka amwe nigice cyumusaruro, hamwe namakarita yerekana ubukana bwurukuta hejuru yinkuta zamazu ya silinderi dukoresheje scan 12 ya Rockwell C. Nuburyo ufata akarere ka chill yoroheje gahindura urukuta rwa mm 30 mo intera yoroheje.
Aho Ishoramari Ritera Gukubita Umusenyi-kandi Iyo Atabikora
Ishoramari ritanga ± 0,05 mm kwihanganira umurongo hamwe na Ra 1,6 µm nkubuso burangije-ingenzi kumazu ya pisitori ya pompe ya piston aho kashe ya geometrie itegeka igipimo cyo kumeneka. Ariko tubwira abakiriya imbere: niba igice cyawe gifite uburemere burenga 45 kg cyangwa gifite ibice byimbere mugari kurenza mm 8, guta umucanga akenshi bitanga ihame ryiza ryibanze hamwe nigiciro gito kuri kilo. Twagiye kure yamagambo aho umucanga watanga urukuta rukomeye-kuberako ubunyangamugayo burinda kunanirwa kumurima.
Imikorere yacu ya Hybrid ikora icyuho. Kurugero: winch center shaft rollers itangira nkishoramari-ishora ibyuma (ASTM A), hanyuma ikanyuzwa CNC ifungura imisarani 5-axis kugeza ibinyamakuru byukuri bitwara 0.015 mm TIR. Ubuvuzi bukurikira bukurikira - kuzimya 890 ° C, ubushyuhe kuri 620 ° C - hanyuma kurasa hejuru kugirango bitere +280 MPa hejuru yo guhagarika umutima. Igisubizo? Ubuzima bwa Shaft bwongerewe 3,7 × mumashanyarazi yimodoka ya offshore aho umunyu wuzuye umunyu wihuta.
Bane Bidashidikanywaho mubikorwa Byinshi-Gukora Ibyuma
Icyo ari cyo cyose uruganda rukora ibyuma bishora uruganda rukora uruganda gusaba kwizerwa bigomba kwerekana ibi bine:
- Gukurikirana ibikoresho kugeza kumubare wubushyuhe-Ntabwo ari urusyo gusa, ahubwo raporo yerekana ibyerekanwe kuri Si, Mn, P, S, hamwe na Cu / Ni / Cr isigaye muri buri cyiciro;
- Igenzura ryuzuye- dukoresha ibizamini bya helium kumeneka, ntabwo ari ubugenzuzi gusa;
- Mubikorwa-byo kurinda amarembo—CMM igenzura nyuma yo guta ibishashara, nyuma yo kurasa, na nyuma yo guturika-mbere yo gutunganya;
- Kwemeza imikorere kumikorere yikizamini-Kwemeza imibiri itemba-yapimwe kuri 1.5 pressure umuvuduko; inzu ya pompe izunguruka-iringaniye kugeza kuri G2.5.
Twanze 8.3% yingingo zambere-zitari zo kwisiga, ariko kubera ko guhamagarwa kwa GD&T hejuru yimiterere ya flange yarenze 0.03 mm kwihanganira uburinganire. Iyo disipuline ikomeza kugeza ku gipimo giciriritse gikora: sisitemu yo guteganya gahunda igenera igihe cyo gukonjesha ibishishwa-byumye-byumuzunguruko mugihe ubushuhe bwimvura bwiyongereye hejuru ya 75% RH. Kuberako gukina ntabwo bijyanye nikirere cyiza-ni ukugenzura impinduka ushobora gupima.
Ibyo ba injeniyeri bakeneye mubyukuri - ntabwo aribyo udutabo dusezeranya
Ukeneye gusobanuka mugihe cyo kuyobora ibicuruzwa: gushora imari byongera ibyumweru 2–3 byo gukoresha ibikoresho no kubaka shell, ariko bikuraho imashini ya kabiri kuri 68% yibiranga muburyo busanzwe bwa pompe. Ukeneye gukorera mu mucyo kuri cobalt-alloy ihuza-dusanzwe dushyira AMS 5387 hamwe nicyuma cyangiza muri sisitemu yo gusangira, ariko nyuma yo kwemeza kwaguka kwubushyuhe budahuye hakoreshejwe ibintu bigereranywa imbere. Ukeneye umuntu uzashyira ahagaragara amakimbirane ya GD&T hakiri kare: twafashe kwihanganira imyanya 0,02 mm kuri mwobo wa mm 12 ya dowel byasabye kwimura gahunda yose ya datum-uzigama $ 24k muri casting zaciwe.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ntagurisha casting. Dukemura uburyo bwo kunanirwa imikorere - inzira ziva, kugoreka ubushyuhe, kwambara nabi - muguhuza metallurgie, physics process, hamwe nubushake bwo gushushanya. Imbaraga zacu zishingiye mugukora ibintu bike, ariko kubikora hamwe nibisubirwamo byanditse: kuva T800 cobalt nozzles ikoresha icyuma gishongeshejwe 650 ° C kugeza kumashanyarazi ya pompe irokoka imyaka 15 yoherejwe hanze yubutaka nta gutwikira.
Niba umushinga wawe utaha ubisabye uruganda rukora ibyuma bishora uruganda rukora uruganda ubushobozi bushinze imizi mu gupima - ntabwo kwamamaza - tangira ushushanya gusubiramo. Tuzakubwira ibikorerwa, ibikenewe gusubirwamo, kandi neza aho ibyago bituye. Ntabwo ari amagambo adasobanutse. Muri microns, megapascal, numubare wubushyuhe bwibintu.
