Icyuma gisize icyuma gitanga uburebure butagereranywa hamwe nigiciro cyibikoresho bikenerwa ninganda-cyane cyane aho guhindagurika, kwangirika kwambaye, hamwe nubushyuhe bwumuriro cyane. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twakoze imashini zirenga 12,000 zogosha ibyuma kumibiri ya hydraulic valve, amazu ya pompe, hamwe ningoma ya feri yimodoka kuva muri 2020. Buri gice gihura na ASTM A48 Icyiciro cya 30B imbaraga zidasanzwe (207 MPa), hamwe na grafite flake morphologie igenzurwa nubwoko bwa A7 kuri ASTM. imirongo ya silinderi munsi yumuvuduko wikizamini.
Kuki Icyuma Cyicyatsi Cyatsinze Ahantu
Ba injeniyeri bamwe batekereza ko ibyuma cyangwa ibyuma bigomba gusimbuza icyatsi kibisi mubisabwa. Ariko amakuru nyayo yisi avuga inkuru itandukanye. Mu bushakashatsi buherutse gukorwa ku nyubako ya pisitori ya piston 475 hirya no hino mu mato ya serivisi y’amavuta yo muri Amerika ya Ruguru, verisiyo y’icyuma yamaze igihe kirekire 18% ugereranije n’ibice bingana n’ibyuma byangiza munsi y’imizigo 3.000-psi. Kubera iki? Igishushanyo cya grafite gikora nk'ibigega byubatswe mu gihe cyo gusiga imbibi - kandi bigakurura imbaraga zinyeganyeza ubundi zikwirakwira mu kashe no ku kashe.
Ibi tubibona buri munsi mumurongo wo guterera umucanga: mugihe abakiriya bahinduye ibyuma byumuyaga bikajya kuri ASTM A159 G3000 icyuma cyumukara kumashini ya shitingi ya winch center, igihe cyo gukora kigabanukaho 22% kubera ubukana buke (187-222 HBW na 241-2269 HBW) hamwe nimyitwarire yo kumena chip. Ibyo ntabwo ari theoretical-byapimwe kuri Okuma MULTUS U3000 mult-axis CNCs mugihe cyo kurangiza ibikorwa. Nta nzara ikonje. Nta gikoresho cyo kuganira. Ubuso buhoraho burangirira kuri Ra 1.6 µm.
Icyuma kijimye kandi gikemura ibibazo byo gucunga ubushyuhe ibindi bikoresho ntibishobora. Urufatiro rwa pompe rugaragaramo amazi ashyushye rimwe na rimwe (urugero, 60 ° C kugeza kuri 120 ° C mukuzunguruka amasegonda 90) yerekana 40% kugoreka ubushyuhe bwumuriro hamwe nicyuma cyumuhondo nicyuma 316. Impamvu? Ubushyuhe bwo hejuru cyane (50 W / m · K na 16 W / m · K) hamwe na coefficient yo hasi yo kwagura ubushyuhe (10.4 × 10⁻⁶ / ° C na 16 × 10⁻⁶ / ° C). Turabigenzura dukoresheje infragre ya thermografiya mugihe cyo kugerageza imikorere-nta gukeka.
Igiciro Cyihishe cya "Guhendutse" Icyuma Cyuma
Ibyuma byose byijimye ntibikora kimwe. Twagenzuye amagambo 31 yatanzwe kubatanga ASTM A48 Icyiciro cya 25 cyumuvuduko wicyuma cyumuvuduko wa valve-dusanga 68% byananiranye kugenzura ibyuma byibanze. Ibibazo bisanzwe birimo fosifore ikabije (> 0,12%), ibintu bya pearlite itagenzuwe (<80% muri zone zitwara imizigo), hamwe na karisiyeri ya magnesium isigaye kuva ibyuma bisuka mbere. Izi nenge zitera kuvunika gucitse mugitangira gikonje cyangwa kugabanuka kugipimo nyuma yubushyuhe bwamagare.
Kuri QINGDAO QIANGSENYUAN, buri cyuma gishonga cyicyatsi gitangirana nicyuma gito cya fosifore cyemewe (≤0.05% P) hamwe nabatunganya ingano ya ferrosilicon. Dufite karubone ihwanye na (CE) hagati ya 3.7-4.1 kugirango turinganize amazi n'imbaraga - ntituzigera twirukana umubare munini utitaye ku mashini. Itanura ryacu ryerekana sulfure, manganese, nigipimo cyo gukonjesha mugihe nyacyo. Niba CE irenze ± 0.05, dukuraho ubushyuhe-ntitumanure.
Iyo disipulini iratanga umusaruro. Abakiriya bavuga ko zeru zananiranye kuri AMS 5387 ihuza ibyuma bya pompe yicyuma cyumuyaga mugihe cyamezi 42 yo gukomeza gukora mumahuriro yuburasirazuba bwa Aziya yepfo. Kurwanya ruswa ntabwo byikora-ariko microstructure yacu igenzurwa irwanya guhagarika sulfide kumeneka neza kuruta amanota rusange.
Igihe cyo Guhitamo Icyuma Cyicyatsi Kurenza Ibindi
Hitamo icyuma gisize icyuma mugihe gusaba kwawe:
- Kunyeganyega - ingenzi kubikorwa bya compressor base, ibikoresho byo kugabanya ibikoresho, hamwe namakadiri yikizamini
- Kwisiga amavuta yo kwambara - nibyiza kuvuza ingoma, amasahani, hamwe nuburyo bwo kunyerera
- Ihagarikwa ryimiterere munsi yumukino wo gusiganwa ku magare - byerekanwe muri moteri, moteri nyinshi, hamwe nubushyuhe bwo guhinduranya ubushyuhe
- Igiciro-cyoroshye-umusaruro mwinshi - ibikoresho byuma byuma byuma bikoresha 30-50% munsi yishoramari ryibice> 5 kg
Irinde icyuma cyijimye gusa mugihe hagomba gukenerwa ingaruka zikomeye (urugero, amenyo yindobo ya excavator) cyangwa mugihe imenyekanisha rirenze 500 ° C ubudahwema. Kubindi byose - harimo na valve yumuvuduko wagera kuri 10,000 psi, inzu ya pisitori ya pisitori ya pisitori ifite 0.025 mm yihanganira kwihanganira, hamwe na moteri yimashini ikora imashini itwara toni 80 zihagarara - icyuma cyumukara gikomeza guhitamo.
Ubufatanye nyabwo butangirana nubwenge bwibikoresho
Guhitamo ibara ry'icyuma ntigomba gusobanura guhitamo igiciro n'imikorere. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata guhitamo ibikoresho nkubuhanga bukorana - ntabwo ari amasoko. Itsinda ryacu risubiramo guhamagarwa kwa GD&T mbere yo gusubiramo, ibendera rishobora kugabanuka kugabanuka mubice bito, kandi byemeza ibishushanyo mbonera byerekana ibizamini bisuka. Ntabwo twohereza ibicuruzwa gusa-dutanga microstructures yagenzuwe, ibyanditswe bikurikirana kugeza ku mubare w'ubushyuhe, na raporo zingana zashyizweho umukono n'abagenzuzi bemewe na CMM.
Kubakiriya bagaragaza ibara ryicyuma, turasaba gutangirana nibibazo bitatu: Nubuhe buryo bwiganje muburyo bwanone mugushushanya kwawe? Ni ubuhe buso butwara imitwaro n'ibisabwa gushyirwaho ikimenyetso? Nigute amashanyarazi yumuriro azagabana igice mugihe gikora? Subiza ibyo - kandi tuzaguhuza nicyiciro gikwiye, inzira yo gutunganya, hamwe na protocole yo kugenzura.
Icyuma gisize icyuma ntabwo ari tekinoroji yumurage. Nibisubizo byakozwe neza neza binonosoye mumyaka 150-kandi biracyahinduka. Ku kigo cyacu cyujuje ISO muri Qingdao, buri gusuka gutera imbere ubwihindurize. Kuberako kuramba ntabwo ari imbaraga gusa. Byerekeranye no guhanura. Guhoraho. Kugenzura.
