Ibyuma bitagira umuyonga ku ruganda rukora ibikoresho byingufu birasaba ibirenze kurwanya ruswa - bisaba guhagarara neza munsi yumukino wo gusiganwa ku magare, uburinganire bwa microstructural kuri 400 ° C +, no kutihanganira na gato kwihanganira akarere k’umuvuduko mwinshi. Twabonye amazu atatu yananiranye ya turbine valve yagarutse avuye mu rugomero rw'amashanyarazi rwo mu majyepfo y'uburasirazuba bwa Aziya kubera ko uruganda rwasibye ibizamini bya ultrasonic kuri zone weld. Niyo mpamvu rero kwerekana ibyuma bidafite ingese mu ruganda rukora ibikoresho bisobanura guhuza ubumenyi bwa siyansi, kugenzura ibikorwa, no kwemeza imikorere - ntibitondere agasanduku k'amanota nka "CF8M".
Kuki gushora imari bikubita umusenyi kubintu byingenzi byingufu
Ntabwo ibyuma byose bidafite ingese bikora kimwe murwego rwo hejuru rwumuriro. Mu mezi 18 ashize yo kuvoma amazu ya pompe kubakiriya ba peteroli na gazi yo hanze, ibice 316L byashoramari byerekanaga microcrake nkeya 42% nyuma yikurikiranya ryumuvuduko 5000 hamwe nibice bingana n'umucanga. Kubera iki? Gutera ishoramari bitanga kwihanganira cyane (± 0.3 mm vs ± 1,2 mm), kurangiza neza neza (Ra 3.2 µm vs Ra 12.5 µm), hamwe nuburinganire bwimbuto - birakomeye mugihe igice cyawe gitsindagiye pompe yo kugaburira imitwe miremire ikora kuri bar 220.
Gutera umucanga bikomeza kuba ingirakamaro kubishingwe binini, bidafite imbaraga-nkibishingwe bya pompe cyangwa ama frame ya turbine - aho uburemere nigiciro byiganje. Ariko kubiterane bizunguruka, imibiri ya valve, cyangwa amazu yumutego wamazu, gushora imari ntabwo biganirwaho. Twemeza buri cyiciro hamwe nisesengura ryikigereranyo, ibizamini bya tensile kuri ASTM A743, hamwe no kugenzura amaradiyo kuri ASME BPVC Icyiciro V. Ntakidasanzwe.
Guhitamo Ibikoresho Ntabwo Byerekeranye Numubare Wamanota
"316 idafite umwanda" ntacyo ikubwira kubyerekeye imikorere-nyayo. Turabaza ibibazo bitatu mbere yo gusubiramo: Ubushyuhe bukabije bwo gukora ni ubuhe? Ese chloride irahari - ndetse no saa kumi n'imwe z'umugoroba? Ibigize bifite umunaniro wubukanishi cyangwa umutwaro uhagaze gusa?
- Kumazi yo mu nyanja akonje: Turerekana F44 (UNS S32750) super duplex - ntabwo ari 316 - kubera ko PREN> 40 irwanya guhuza aho chloride yibera mumigezi.
- Kuri pompe ya geothermal brine: ASTM A995 Gr. 6A (CD4MCu) ikora H₂S + CO₂ kurenza amanota ya duplex asanzwe bitewe na ferrite igenzurwa / austenite.
- Kuri serivisi za kirimbuzi: CF3M castings ikemura igisubizo cyuzuye annealing + kuzimya kuri ASTM A351, hanyuma ikizamini cyo kwangirika hagati yimiterere ya ASTM A262 Imyitozo E.
Twanze ibintu fatizo bidafite raporo yikizamini cyerekana ibintu-cyane cyane sulfure (<0,015%) na ogisijeni (<0.002%). Umukiriya umwe yamaraga amezi 12 yamanutse yagarutse kuri sulfure yazamuye itera amarira ashyushye mugihe cyo gutunganya bwa nyuma. Iri somo ryahinduye protocole yacu yo kugenzura-niyabo.
Kwishyira hamwe guhagaritse gukemura ibibazo byububabare nyabwo
Kunanirwa kwinshi ntibibaho muri casting - ahubwo bibaho hagati yo gukina no gutunganya. Umubiri wumucanga wumucanga urashobora kunyura kuri NDT, nyamara ugatera mm 0,15 mugihe cyo gusya CNC kubera guhangayika. Twakuyeho izo ngaruka mugucunga urunigi rwuzuye: guta → kuvura ubushyuhe bwo kugabanya ubushyuhe → gutunganya imashini → gusaza → kurangiza gukora → kugenzura CMM.
Ikigo cyacu cyujuje ISO gikurikirana uru rutonde munsi yinzu. Dupima buri kantu katoroshye hamwe n'ibipimo byo mu kirere byahinduwe buri munsi; genzura kwibanda kuri valve stem bores ukoresheje igereranya optique; n'ikarita yubuso bukomeye hejuru yubushyuhe bwakorewe hamwe na bipimisha Rockwell. Mugihe umukiriya wu Burayi yari akeneye amazu 48 ya guverineri ya turbine yatanzwe mu byumweru 11, twubatse icyitegererezo, dusuka, dukora imashini, kandi twipimishije - byose murugo. Nta ntoki. Nta gushyikirana nabi. Nta gahunda yo kunyerera.
Ibi ntabwo byoroshye-ni physics. Gukora casting utazi kugabanwa kwayo ni nko guhuza moteri ifunze.
Ibyo Ukeneye Mubyukuri Mbere yo Gushyira Urutonde rwawe rwa mbere
Ntutwoherereze dosiye ya CAD kandi utegereze amagambo. Zana ibi bintu bine mubisubiramo:
- Igishushanyo cyerekanwe cyerekana GD&T guhamagarwa bigira ingaruka kumikorere - ntabwo ari ubwiza gusa.
- Gukoresha amakuru yibidukikije: ubushyuhe bwa min / min, chimie yamazi (hamwe na pH, chloride, urwego rwa H₂S), hamwe ninshingano zakazi (gukomeza vs intermittent).
- Ibisabwa byo kwipimisha: umuvuduko wa hydrotest, uburyo bwa NDT (RT / UT / PT), hamwe n'ibipimo byemewe (urugero, "nta kimenyetso> 1,5 mm z'uburebure").
- Gukenera gukurikiranwa: Ukeneye uburinganire bwuzuye kugirango ushushe umubare? Icyemezo cyibikoresho kuri EN 10204 3.1 cyangwa 3.2?
Tuzasubiza mumasaha 48 hamwe nibitekerezo byakozwe-harimo ibitekerezo nko kwimura igice cyoroshye-urukuta kugirango twirinde kugabanuka cyangwa kongeramo umushinga wo kugabanya imbaraga zo kurekura. Nuburyo ibyuma bidafite ingese kumashanyarazi yinganda zikoresha ingufu ziva mubikorwa kandi byizewe.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka ibice bikomeza kubaho - ntabwo bihura gusa na spec. Ibyo twibandaho biguma bigufi: gutondeka neza sisitemu ya hydraulic, ibikoresho bya peteroli na gaze, hamwe ninteko ya pompe yakozwe aho gutsindwa atari amahitamo. Ntabwo dukurikirana amajwi. Dukemura ibibazo byurwego, metallurgiki, nibikorwa, duhereye kumasuka ya mbere.
