Iyo ba injeniyeri bagaragaje 420 ibyuma kubintu byambara cyane, birwanya ruswa-nkumubiri wa hydraulic valve, pompe pompe, cyangwa imashini ya winch center - bakeneye ibirenze kubahiriza ibintu gusa. Bakeneye a 420 uruganda rukora ibyuma ibyo birasobanukirwa uburyo kuvura ubushyuhe bigira ingaruka zikomeye, uburyo ibipimo byo gutunganya bigira ingaruka kubusugire bwubuso, nimpamvu ituze ryikigereranyo munsi yumukino wo gusiganwa ku magare kirenze kataloge imbaraga zonyine.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Yatunganije, itunganya ubushyuhe, kandi igenzura ibice birenga 12,000 byabigenewe 420 bidafite ibyuma kuva 2018 - cyane cyane kububiko bwa peteroli yo muri Amerika y'Amajyaruguru OEMs hamwe n’ibikorwa bya hydraulic sisitemu yo mu Burayi. Twabonye ubwacu uburyo annealing idahuye iganisha kuri micro-crack mugihe cyo gusya kwa nyuma. Twakosoye umuhamagaro wa GD&T wibwiraga ko kugabanuka kwa isotropic-ariko 420 SS castings ntabwo yitwara gutya nyuma yo kuzimya. Kandi twongeye gukora ibishushanyo aho "indorerwamo irangiza" yerekanwe tutarinze gusobanura imipaka ya Ra-gusa dusanga igice cyatsinzwe ikizamini cyo gutera umunyu mumasaha 96 kubera guhangayikishwa nubutaka.
Niyo mpamvu kwizerwa bitangira kera mbere yuko chip ya mbere iguruka. Ibikorwa byacu bitangirana na fagitire 420 zidafite ibyuma-zishobora gukurikiranwa na raporo y'ibizamini by'urusyo zihura na ASTM A276 na AMS 5630. Tugenzura ibirimo karubone (0.15–0,20%), chromium (12.0–14.0%), hamwe n'ubukomere muri leta yometse (≤200 HB) mbere yo gukata. Nta cyiciro cyinjira mubikorwa bidafite imiti yuzuye ya sprosroscopi na macro-etch yemewe. Kubera iki? Kuberako 0,03% ya karubone ihindagurika ihindura ubushyuhe bwa martensite kuri 18 ° C - kandi ibyo bihindura byose muburyo bukomeye.
Ikigo cyacu cyujuje ISO gikemura ibibazo byuzuye: guhinduranya neza CNC no gusya (harimo na axis nyinshi ihuza ibyambu bigoye), vacuum cyangwa igenzurwa nikirere gikomera (kugeza 52-56 HRC), gutuza kwa kirogenike, hamwe no gusya neza cyangwa gushiramo amashanyarazi hejuru yikimenyetso gikomeye. Twinjiza uburyo bwo kuvura ubushyuhe muri gahunda ya NC - nta bacuruzi bo hanze, nta ntoki, nta cyuho kiboneka. Iyo umukiriya akeneye 54 ± 1 HRC kurutugu rwa piston ya mm 32, dupima ubukomere kumyanya itatu ya radiyo * na * ubujyakuzimu-ntabwo ari hejuru gusa. Ibyo ntibishobora kuganirwaho kubice bikoresha 3000 psi hamwe nubuzima bwumunaniro 150.000.
- Nta bubiko butari mu bubiko.
- Nta gukekeranya: Ibintu byose byingenzi byagenzuwe ukoresheje Zeiss CMMs yahinduwe kuri NIST-ikurikiranwa; GD&T yasobanuwe neza, ntabwo yapimwe gusa
- Nta kurangiza buhumyi.
- Nta kunanirwa n'ingingo imwe: Full lot traceability—from heat number to operator ID to inspection timestamp—embedded in our ERP
Bamwe bashobora kuvuga ko gutera ibyuma 420 bidafite ingese bidakwiye kubera ingaruka zishyushye. Turabyemera-niba ukoresha umusenyi wo guterana hamwe na gati isanzwe. Ariko amazu yacu ashora 420 SS kububiko bwa pompe yomwamazi akora neza muri serivise yinyanja kuko tugenzura icyerekezo cyo gukomera, tugakoresha ibishushanyo mbonera bya ceramic hamwe na silika nkeya, kandi tugakoresha gradients preheat igabanya ihungabana ryumuriro kuri 40%. Ntabwo ari amarozi. Ni disipuline ya metallurgiki ishyigikiwe nimyaka 11 yuburambe bwa cobalt-alloy-aho imicungire yubushyuhe ikora-cyangwa ikavunika.
Tuzi kandi icyo ibyuma 420 bidafite ingese * bidakora * neza - kandi tuzakubwira imbere. Ntabwo izahuza 316 SS muri chloride piting resistance. Ntabwo ari byiza guhora ugaragara hejuru ya 600 ° F. Niba kandi igishushanyo cyawe guhamagarira urudodo rwimbitse, ruto cyane kurukuta ku gice gikomeye, tuzasaba ingamba zo gusya nyuma yubushyuhe bwo gusya insyo aho kwirukana kanseri ivunika kuri 48 HRC. Gukorera mu mucyo ntabwo ari politiki hano. Nisuku yubuhanga.
Kubakiriya batanga ingingo-ngingo ya mbere, isuzuma ryubwubatsi ryacu ririmo ibitekerezo byubusa: kumenya ingaruka ziterwa nimpinduka zuzuye, kwemeza gukomera kubice byambukiranya> mm 25, hamwe no kwerekana ibibanza aho amashanyarazi ashobora kuzamura okiside yubutaka aho kuyikuraho. Twakumiriye ivugurura ryibikoresho 23 mu mezi 18 ashize - ntabwo tuvuze ngo "yego," ahubwo twerekana neza aho ingaruka ziba.
Niba ushakisha 420 uruganda rukora ibyuma abafatanyabikorwa kubikorwa byinganda zinganda, reba ibirenze ibyemezo. Baza uburyo bemeza ubukana bwimbitse. Baza icyitegererezo cya micrografi yerekana ibice byambukiranya ibice. Baza uburyo bakemura byinshi-byinshi muri chromium carbide imvura. Noneho gereranya ibisubizo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka kuramba-ntabwo amatariki yo gutanga gusa. Icyifuzo cyacu gikurikira: kwagura AMS 5630 yubahiriza 420 SS yubushobozi bwamazu yo mu kirere no guteza imbere imashini ikora imashini ikora imashini igabanya igihe cyo kuyobora ku kigero cya 35% idatanze kugenzura ingano. Ibikoresho ntabwo byahindutse. Ariko burya dufatana uburemere imyitwarire yacyo-nibyo bitandukanya uwabitanze.
