Iyo abajenjeri bagaragaje ibice byicyuma cyangwa imvi kuri sisitemu ya hydraulic, ibikoresho bya peteroli, cyangwa pompe ziremereye, ntibakenera casting gusa-bakeneye gutuza kurwego munsi ya 300+ igitutu, microstructure ihuzagurika mubice 500, na kwihanganira zeru kugabanya ububobere muri flanges yikoreye imitwaro. Niyo mpamvu gushakira ukuri uruganda rukora ibyuma-Ntabwo umukozi wubucuruzi cyangwa ibishingwe rusange-ntibishobora kuganirwaho. Twabonye imishinga myinshi yatinze kubarwa ya grafite nodule idahuye, ubukana bwa Brinell budahuye (HBW 180-22 v. Bisabwa 210-2240), cyangwa inenge zo hejuru zahatiye gukora nyuma yo gukora. Umufatanyabikorwa mwiza akora metallurgie nka disipuline - ntabwo ari ibitekerezo.
Impamvu ubunyangamugayo bwibintu butangira kera mbere yo gusuka
Kunanirwa kwinshi kugaruka kubikoresho fatizo-ntabwo ari tekiniki yo guta. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri cyiciro cyicyuma cyitwa EN-GJS-400-15 gitangirana nicyuma cyingurube cyemewe na ferrosilicon kuva ISO 9001 - byemewe. Bagenzura karuboni ihwanye (CE) bahageze bakoresheje isesengura rya LECO-ntabwo ari amakarita yabatanga gusa. Twapimye ingendo ya CE kugeza kuri ± 0.15% muri tombora itagenzuwe, bitera igihombo cya nodularity mumazu yibice. Laboratwari yabo ikora igenzura rya ASTM A536 kuri buri bushyuhe: imbaraga zingana, kuramba, no gukomera - byose byanditswemo indangamuntu, gusuka igihe, nigipimo cyo gukonja. Nta "cyitegererezo cy'icyitegererezo". Ibi ntabwo birenze urugero-nuburyo bafata inzu ya silinderi ya pompe ya piston kugeza kuri 0.02 mm kuzenguruka nyuma yo kuvura ubushyuhe.
Aho guta umucanga bihura na disipulini ya CNC
Ibice by'icyuma bisa nkibishingwe bya pompe cyangwa umubiri wa valve bisaba uburinganire bukomeye (<0,05 mm hejuru ya mm 600) hamwe na bores zakozwe neza. Nyamara guta umucanga byonyine ntibishobora kubitanga. QINGDAO QIANGSENYUAN ikuraho icyuho hamwe no kugenzura ibikorwa bihagaritse: uruganda rwabo rukoresha ibishanga byumusenyi uhujwe no kugenzura igihe nyacyo, hanyuma ugahita wimurira mu nzu ya selile 5-axis ya CNC. Nta ntoki zo hanze. Ntakigenda kiringaniye hagati yo gukina no kurangiza gutunganya. Bakora imashini ikomeye yo gufunga mugihe casting ikomeje kugabanuka-kugabanya kugabanura ubushyuhe bwa 40% hamwe na mashini nyuma ya annealing. Kumuvuduko wumuvuduko usaba AMS 2700 Icyiciro cya 2 passivation, bahuza kurasa no gusukura aside nitric mbere yo kugenzura bwa nyuma. Ntabwo ari "guta + gutunganya." Ni urutonde rumwe rukora.
Kwemeza-Isi Yukuri: Ibyo Abakiriya Bipima Mubyukuri
Abakiriya ba peteroli yo muri Amerika y'Amajyaruguru ntibemera raporo y'ibizamini-byemeza imikorere. Umukiriya umwe yagerageje kuzunguruka 12 winch center shaft munsi ya 120.000-umunaniro wumunaniro uremereye kuri -20 ° C. Byose byararenganye. Irindi ryitwa cobalt-alloy nozzles (AMS 5387) rirwanya ibishishwa byangiza amasaha 72 - isuri ya zeru irenga 0.03 mm. Ibi ntabwo ari amatsiko ya laboratoire. Nibice byumusaruro byoherejwe hamwe nubushakashatsi bwuzuye: nimero yubushyuhe, icapiro ryimiti yandika, raporo ya CMM kubantu bose bahamagaye GD&T, na micrografi yerekana morphologie kuri ISO 945-1. Iyo pompe yu Burayi OEM yasabye ISO 13003 yujuje ibyangombwa byo kuvunika gukomera kuri EN-GJL-250 icyuma cyumuhondo, batanze Charpy V-notch indangagaciro-ntabwo ari ibintu gusa. Nuburyo wirinda "byasaga neza mugushushanya" gutungurwa.
Guhitamo Uruganda Rwa Iron: Uruganda rutatu rutaganirwaho
- Baza ibyiciro bitatu byanyuma- ntabwo ari ibyemezo. Kugenzura niba ubukana, imbaraga zingana, hamwe nibigize imiti byanditswe kuri buri bushyuhe, ntabwo kuri byinshi.
- Saba gihamya yimikorere ya CMM- ntabwo ari ubugenzuzi bwa nyuma. Ibipimo byingenzi bigomba kugenzurwa nyuma yo gutunganywa bikabije na mbere yo kurangiza gukata.
- Emeza ko bafite imitungo yombi yo gutunganya no gutunganya. Ibikorwa byo hanze byongeweho iminsi 7-12 yo kuyobora igihe no kumenyekanisha amakosa yo guhuza nta nyandiko ya GD&T ishobora gukosora.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihura uko ari itatu. Ikigo cyabo i Qingdao gikora muri ISO 9001: 2015 kandi gikomeza inzira zanditse kuri buri ntambwe - kuva gutegura umucanga kugeza gupakira bwa nyuma. Bohereza muri Amerika ya ruguru, Uburayi, no mu majyepfo y’amajyepfo ya Aziya bafite ibyangombwa bya gasutamo hamwe no kubahiriza RoHS / REACH byubatswe mu bikoresho. Niba inzu yawe ikurikiraho ikeneye kubaho imyaka 20 mumashanyarazi yo mu nyanja - cyangwa icyuma cya pompe yicyuma kigomba kugabanya ihindagurika kuri 3,600 RPM - tangira ukoresheje ibyuma bya metallurgjiya, ntabwo bisaba ibicuruzwa. Abakomeye uruganda rukora ibyuma ntabwo isezeranya gutungana. Yerekana guhuzagurika - ubushyuhe bumwe, guterana, gupima icyarimwe.
