Guhitamo ibishashara byiza kumashanyarazi yatakaye ibikorwa ntabwo ari ugushaka amahitamo ahendutse-ni ugukuraho ingingo zananiranye zihishe mbere yuko zigera ku ziko. Twabonye umusaruro mwinshi uhagaze murwego rwo gutwikwa kubera ibisigazwa byibishashara bifunga ibice byiza mumazu ya pompe ya cobalt. Abandi bakuyeho 30% by'icyiciro nyuma yo guturika ibishishwa - bagaruka ku kwaguka k'ubushyuhe budahuye mugihe cyo kwangiza. Izi ntabwo arizo ngaruka. Nibiciro bya buri munsi mugihe, ibikoresho, no kwizerana kwabakiriya.
Impamvu ibishashara bisanzwe binanirwa gukenerwa ninganda
Inganda nyinshi zitangirana nibishashara rusange byashizwe kumitako cyangwa kumashanyarazi ya aluminiyumu. Ibyo birakora - kugeza igihe ukoresha AMS 5387 cobalt alloy valve umubiri wa 1,550 ° C cyangwa T800 ishingiye kuri nozzles isaba ± 0,05 mm kugenzura ibipimo bya 0.8 mm. Ibishashara bisanzwe ntibiranga ibintu bitatu bidashobora kuganirwaho: gutwika neza ivu munsi ya 650 ° C, hejuru ya zeru nyuma yo kumeneka, no kugabanuka k'ubushyuhe munsi ya 0.45% kuva kuri 25 ° C kugeza kuri 60 ° C. Bitabaye ibyo, ubona ububiko bwa karubone bwangiza hejuru yubuso, gukurura ibishushanyo bigoreka flanges yoroheje, cyangwa micro-crack mu bishishwa bya ceramic mugihe cyo gutemba.
Twagerageje ibishashara birindwi mu nganda mu mezi 18 - harimo ibice bibiri bivangwa na nyirarureshwa - ku bice nyabyo byakozwe: amazu ya pisitori ya pompe ya pisitori, inzu y’amazi ya hydraulic, hamwe na shitingi ya winch center. Batatu gusa batsinze byuzuye-byemewe. Uwitwaye neza ntabwo yari ibishashara-byo hejuru cyane. Nibwo bufite intera ndende (52-54 ° C), ubukonje buke kuri 65 ° C (8,200 cP), hamwe n’ibisigazwa by’ivu biri munsi ya 0.003% nyuma ya 620 ° C / amasaha 2 yatwitse kuri ASTM F2897.
Ibipimo bine bya tekiniki Nta ruganda rugomba gusimbuka
Wibagiwe ibyifuzo byo kwamamaza. Dore icyangombwa mubyukuri mugihe cyujuje ibisabwa ibishashara byo gushora imari-ishoramari:
- Igipimo cyimiterere nyuma yo guterwa: Ibishashara bigomba kwihanganira GD&T binyuze mu gukonjesha - ndetse no ku bice bitamenyerewe nka fondasiyo ya pompe ifite uburebure bwa mm 220 n'ubugari bwa mm 3,2. Dupima kugabanuka ku ngingo eshatu: intangiriro, urukuta rwagati, na flange. Gutandukana byemewe: ≤0.38% impinduka zose zumurongo.
- Guhuza Dewaxing: Kunyunyuza amavuta bisaba byihuse, byuzuye gushonga nta kubyimba cyangwa kubyimba. Ibishashara bifite> 0.8% byubusa amavuta acide ifuro munsi yumwuka wuzuye - bitera igikonoshwa. Pass yagenzuwe: ntagisigara kigaragara muri mm 3 zo gukonjesha imbere nyuma yiminota 12 160 ° C.
- Igenzura ry'igikonoshwa: Kwifata cyane bitera igiceri kumeneka mugihe cyo gukora. Guto cyane bitera guhubuka. Ingufu nziza yibishashara: 34-36 mN / m kuri 30 ° C - bipimwa hakoreshejwe impande ya goniometrie, ntabwo ari datasheet.
- Imipaka ikoreshwa: Ibishashara byongeye gukoreshwa bitesha agaciro vuba mu bice bihindagurika. Turakurikirana flash point igabanuka hamwe na aside izamuka. Koresha imipaka: max 3 cycle niba umubare wa aside ugumye <0.8 mg KOH / g na flash point ikomeza ≥110 ° C.
Uburyo QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Yemeza Imikorere y'Ibishashara
Ku kigo cyacu cyujuje ISO muri Qingdao, impamyabumenyi y'ibishashara ntabwo ari imyitozo ya laboratoire-ni irembo ry'umusaruro. Buri gishashara gishya gikora ibizamini bine icyarimwe:
- Ikigeragezo cyibice 50 cyigice cyabakiriya nyacyo: AMS 5387 cobalt alloy plug hamwe na 0.5 mm kwihanganira imirasire kuri mm 12 OD.
- Ibipimo bya CMM mbere na nyuma ya dewaxing kugirango bagereranye uburyo bwo kugoreka.
- Isesengura rya Thermogravimetric (TGA) ryibisigazwa byumuriro hejuru yicyuma - byagenzuwe na mape yibanze ya SEM-EDS.
- Gusaza byihuse: amasaha 72 kuri 40 ° C / 85% RH, hagakurikiraho imbaraga zingana no kwipimisha kuramba kuri ASTM D638.
Iyi nzira yafashe igishashara kimwe cyujuje impapuro zose - ariko ikizamini cyatsinzwe # 2. Coefficente yo kwagura ubushyuhe yazamutse hejuru ya 85 ° C, itera 0,12 mm kurenga ku rutugu rukomeye. Icyo gice cyaba cyaratsinze igenzura ariko cyasohotse kuri 350 bar muri serivisi yo murwego. Ntabwo twohereza ibitekerezo. Kohereza amakuru.
Guhitamo Igishashara cyawe: Igikorwa Intambwe Zikurikira
Ntukishingikirize kubitanga byonyine. Koresha uru rutonde mbere yo kurangiza ibyawe ibishashara byiza kumashanyarazi yatakaye guhitamo:
- Saba umurongo wuzuye wa TGA-ntabwo ari "gusa ivu". Saba uburemere busigaye% 550 ° C, 600 ° C, na 650 ° C.
- Gerageza dewaxing kuri sisitemu yawe yuzuye: binder imwe, stucco imwe, gahunda yo kumisha. Ibishashara byuzuye kuri silika sol shells birashobora kunanirwa bikabije hamwe na colconidal zircon.
- Emeza ibipimo byo gutera inshinge kuri mashini yawe: ubushyuhe bwa nozzle, kuzuza umuvuduko, umuvuduko wapaki. Ihinduka rya 2 ° C muri temp temp irashobora guhindura ubukana bwa Ra kuri 0.4 µm - bihagije kugirango bigire ingaruka kumazi ya ceramic.
- Saba ibyiciro bikurikirana: nimero myinshi, ibyemezo byibikoresho fatizo, na raporo ya QC ihuye nuburyo waguze. Nta na kimwe kidasanzwe.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Inkomoko yemejwe ibishashara byujuje ibi bipimo byumusaruro wabyo - kandi igabana protocole yuzuye yo kwemeza hamwe nabafatanyabikorwa babishoboye. Kuberako ibishashara bihoraho ntabwo ari ikigo cyigiciro. Nibice byambere byubunyangamugayo buringaniye kuri buri cyuma cyumuvuduko, inzu ya pompe, buri kintu cobalt alloy cyubatswe kugirango kibeho kugirango isi ibeho.
Reba ibirenze gushonga. Gupima kugabanuka. Kurikirana ibisigisigi. Emeza geometrie yawe. Nuburyo uhagarika kwirukana inenge-hanyuma ugatangira kohereza ibice bikora.
