Uruganda rukora ibyuma bya Austenitike rugomba gutanga ibirenze ibyo kubahiriza ibintu - bigomba kwemeza kurwanya ruswa irokoka serivisi nyayo: guhura na chloride nyinshi mu mazi yo mu mazi, gusiganwa ku magare mu mazu ya pompe, cyangwa guhuza ibinyabiziga muri sisitemu yo gutwara ibinyabiziga. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twakoze ibyuma birenga 12.000 bya austenitike bitagira ibyuma byumuvuduko wamazu hamwe n’amazu ya pisitori ya piston pompe kuva muri 2019 - kandi isesengura ryose ryatsinzwe ryatwigishije ikintu kimwe: kurwanya ruswa ntabwo bitetse mu cyiciro. Yahimbwe mugucunga inzira.
Kurwanya ruswa bitangira mbere yo gukora-Ntabwo nyuma
Abaguzi benshi bibwira ko ASTM A351 CF8M cyangwa UNS S31603 ihita ihwanye na "ruswa." Baribeshya. Twabonye imyanda imwe yananiwe mubidukikije byamazi yinyanja-imwe yatsinze amasaha 2000 yipimisha umunyu; ikindi cyashyizwe mu masaha 72. Impamvu? Ntabwo gutandukana kwa chimie - ahubwo gukomera bidahuye mugihe cyo guta umucanga. Microsegregation yaho yaremye zone chromium-depletes zone kumipaka interdendritic. Gukosora ntibyari gusubiramo. Yashushanyaga sisitemu yo kwinjirira, yongeramo ibyapa bikonje, kandi ifite ubushyuhe bwicyuma muri ± 5 ° C mugihe cyo gusuka. Nuburyo dufata numero ya ferrite hagati ya 5–8 FN muri buri CF8M ya casting-yagenzuwe na magnetiki probe * mbere yo kuvura ubushyuhe, ntabwo nyuma.
Ntabwo dusohora metallurgie. Ibikoresho byacu bibisi bikurikirana buri bushyuhe kugeza kuri raporo y'ibizamini (MTRs) byerekana ibirimo Cr, Mo, Ni, na N - ntabwo "bihura gusa na sp." Kubikorwa byingenzi nka AMS 5387 cobalt alloy pompe ikora hamwe ninzu ya austenitike, turagenzura guhuza galvanic binyuze mumashanyarazi ashobora gupimwa muri electrolytike ya serivise. Niba itandukaniro rishobora kurenga mV 50, duhindura ibipimo bya passivasi yubuso - nubwo ibivanze shingiro "ari byo."
Aho Uruganda rwinshi rwa Austenitike rutagira ibyuma rusaba gusenyuka
Bamwe mubatanga ibicuruzwa bahagarika ibikoresho "byemewe na ISO" mugihe bakoresha kaliperi yintoki kugirango bagenzure bwa nyuma ibinyamakuru byihanganira 0.005 mm. Ntabwo. Buri gice cya austenitis kitagira ibyuma gisiga ikigo cyacu cya Qingdao gikorerwa igenzura eshatu zidashobora kumvikana:
- Kugenzura ubusugire bwubuso.
- Kwemeza ibice byemewe.
- Ikarita yo gushushanya: Gutandukanya X-ray ahantu 5 byingenzi kuri buri gice, cyane cyane hafi yuzuza nudodo-kubera ko guhangayika hejuru ya 200 MPa byihutisha SCC mubidukikije bya chloride
Imwe mu mazi ya hydraulic OEM yanze kohereza bwa mbere shingiro rya pompe ya S31603 - ntabwo ari amakosa yibipimo, ahubwo ni impagarara zisigaye hafi yimyobo. Twashubije hamwe namakarita yuzuye yo guhangayika, hanyuma dushushanya uburyo bwo gufunga hanyuma twongeramo imbaraga zo kugabanya imbaraga zo guhindagurika gusaza mbere yo gutunganya bwa nyuma. Gutanga byagabanutse ibyumweru bibiri. Ubuzima bwa ruswa bwongerewe kuva kumezi 18 kugeza 47 mugihe cyibigeragezo. Nibyo gucuruza nta datasheet yerekana.
Imikorere-Isi Yukuri Irasaba Kurangiza-Isi
Gukoresha ibimenyetso bifite akamaro. A 0.8 µm Ra kurangiza irashobora guhura nigishushanyo-ariko niba ibyo bimenyetso bigenda bisa nicyerekezo gitemba mumubiri wa valve, bihinduka ibibanza byo gutangiriraho ruswa. Twerekeje inzira yibikoresho kugirango duhuze serivisi zipakurura: umuzenguruko wo kuzunguruka, kuzenguruka amazu ahamye, hamwe na radiyo ivanze ninzibacyuho. Kubice bya T800 bishingiye kuri cobalt byasuditswe mu nteko za austenitis, dukoresha amashanyarazi * nyuma yo gusudira - atari mbere - kugirango dukureho okiside yibasiwe nubushyuhe tutiriwe dukata urutoki.
Tuzamurwa cyane? Passivation hamwe na acide citric + sodium nitrati aho kuba aside nitric gakondo. Kubera iki? Kuberako acide citric ikuraho fer yubusa idashonga chromium-ikomeye mugihe itunganya ibice bya Hybrid duplex-austenitis. Twemeza ibisubizo hamwe no gupima umuringa wa sulfate * na * ferroxyl yerekana igisubizo, tugenzura isuku yubuso hamwe na firime ya pasiporo. Abakiriya batanga raporo 3.2 × bike byananiranye mumirima mugushiraho nyuma yo guhinduranya.
Guhitamo uruganda rukora ibyuma bya Austenitike bisobanura guhitamo umufatanyabikorwa
Niba gusaba kwawe kurimo umuvuduko ukabije, ubushyuhe bwo hejuru, cyangwa kuvanga-ibintu, urwego rwibintu ni intambwe yambere. Intambwe ya kabiri ni ukugenzura uburyo utanga isoko agenzura amacakubiri, imihangayiko, hamwe nubuso bumeze mubice. Intambwe ya gatatu iremeza ko QA yabo idahagarara kubipimo-bipima imyitwarire yamashanyarazi, microstructural homogeneity, hamwe no kuramba kumurimo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora nk'iyaguka ry'itsinda ryawe ryubwubatsi-ntabwo rigurisha ibice. Dufatanije gusubiramo GD&T guhamagarwa kubikorwa byingaruka zo kurwanya ruswa. Dushira ibendera kubashakanye galvanic mbere yuko casting itangira. Tugumana ibintu byuzuye bikurikirana kugeza kuri numero yumubare hamwe nubushyuhe bwo kuvura cycle. Kandi iyo ruswa igaragara muri serivisi, ntabwo twohereza umusimbura-twohereza raporo-nyirabayazana ya raporo hamwe na metallurgical cross-section na protocole yo gukosora.
Kurwanya ruswa kwizewe ntabwo byemejwe n amanota. Yinjiza mu ruganda, yemejwe muri laboratoire, kandi yemejwe mu murima. Nibisanzwe buri ruganda rwa austenitike rutagira ibyuma rugomba guhura-ariko bake mubyukuri barabikora.
