Iyo abajenjeri bagaragaje ibice bya pompe hydraulic, valve yamavuta ya peteroli, cyangwa sisitemu ya winch iremereye cyane, "uruganda rukora imashini zikora neza" ntabwo ari ijambo ryishakisha gusa-nibisabwa bidashoboka. Ihame ryimiterere munsi ya 50 µm kwihanganira. Microstructure ubunyangamugayo nyuma yo kuvura ubushyuhe. Kurangiza isura irwanya gutembera mumuvuduko mwinshi wamazi. Ibi ntabwo ari ibipimo ngenderwaho. Nibyo bituma pompe ya piston ikora kuri 3000 psi mumezi 18 idatemba-kandi itandukanya prototypes ikora nibice byemejwe numurima.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora uruganda rukora imashini nziza cyane aho cobalt-nikel alloys idacibwa gusa-barumva *. Twabonye abakiriya bohereza AMS 5387 cobalt alloy inzu ya pompe 6 isubizwa kabiri: ubanza hamwe na micro-crack hafi yubushyuhe butunganijwe, hanyuma hamwe na GD&T guhamagarwa bisobanuwe nabi nkibihugu byombi aho kubogama. Kunanirwa kwombi kwerekanwe kumateka yubushyuhe adahuye - ntabwo kwambara ibikoresho. Niyo mpamvu ikigo cyacu gihuza casting, axis-axis CNC, hamwe no gutunganya ubushyuhe nyuma yo gutunganya munsi yinzu. Nta ntoki. Nta cyiciro-cy-icyiciro gitembera muburyo bw'ingano. Gukurikiranwa gusa, gusubirwamo, kugenzura inyandiko.
Ubushobozi bune busobanura ukuri-kwisi-ntabwo ari impapuro zerekana gusa:
- Ubuhanga bwa Cobalt-nikel burenze imibare: T800 ibikoresho bishingiye kuri cobalt ntabwo bikora nkibyuma bitagira umwanda. Igipimo cyacyo cyo gukomera kizamuka nyuma ya 0.1 mm yuburebure. Dukoresha ibikoresho bya PCD byabigenewe geometrike, gutanga korojene itangwa, hamwe nigihe gikurikiranwa cyo kugenzura imitwaro-sibyo kuko irabagirana, ariko kubera ko twapimye 42% ubuzima bwibikoresho birebire kuri cobalt alloy nozzles mugihe igipimo cyibiryo kigabanutseho 15% kuri pass ya 0.05 mm yanyuma.
- Kwishyira hamwe guhagaritse birinda gutembera kurwego: Urufatiro rwumucanga pompe urufatiro rukunze kurwara mugihe cyo kugabanya imihangayiko. Niba gutunganya bibaye nyuma yicyumweru kuri subcontractor, ubura ububiko bwumuriro bwa casting. Imashini zacu zikoreshwa mumasaha 72 yo kuvura ubushyuhe - gupima kugoreka hamwe na Zeiss CMM mbere na nyuma, ihindura ibice mugihe nyacyo. Igisubizo: imyubakire ya silindiri ifite ± 0,015 mm kuzenguruka kuri mm 300 z'uburebure, ndetse no kuri 45 kg.
- Kurangiza imikorere - ntabwo kwisiga: Intebe yumuvuduko wumuvuduko ntabwo ari Ra 0.4 µm. Byerekeranye na plateau honing ikora 45% yikibanza kuri 0.8 µm yibanze, bityo guhuza iminwa ikagabanya imizigo iringaniye. Twemeza kurangiza byose hamwe na profilometrie hamwe na epoxy ikoporora-ntabwo igenzurwa gusa. Abakiriya bahinduye ibintu rusange "byoroshye kurangiza" batanga raporo 3.2 life igihe kirekire cyigihe cyo gukora mumateraniro ya pompe yo hanze.
- GD&T nkibiganiro byubuhanga - ntabwo ari ubusobanuro: Iyo umukiriya ashyizeho ikimenyetso "Ø25.000 + 0.005 / –0.000" kuri roller yo hagati, ntabwo dukeka ko ISO 2768 iciriritse. Turabaza: Ibi nibyo kubangamira itangazamakuru? Kuringaniza imbaraga? Kugirango habeho kwagura ubushyuhe? Noneho dushushanya buri datum kumurongo wingenzi, twigana kugoreka ibintu muri NX, hanyuma tugasubiza ibishushanyo bisobanuwe - ntabwo "byemewe." Nuburyo twafashe intego ya datum idahuye kuri shitingi yimodoka ya winch shaft yaba yarateje 0,12 mm kwiruka kumuvuduko wo gukora.
Bamwe bavuga ko urunigi rutangwa ku isi rutuma ubusobanuro bwaho butagikoreshwa. Ariko gerageza ushakishe icyuma kidasanzwe cya cobalt koresha imiyoboro ikonjesha imbere, uburebure bwa mm 0,02, hamwe na AMS 5737 kubahiriza - hanyuma utegereze ibyumweru 14 kugirango ibicuruzwa bitwarwa mu kirere, ubukererwe bwa gasutamo, hamwe n’ibikorwa byo gukora. Turatanga ayo mashanyarazi muminsi 22 yakazi, hamwe nibikoresho byuzuye (MTRs), ibiti bivura ubushyuhe, hamwe na raporo ya CMM yashyizwe mubikoresho byoherezwa. Ntabwo woherejwe nyuma. Ntabwo "biboneka kubisabwa." Mu gasanduku.
Ikigo cyacu cyujuje ISO muri Qingdao gikora ibirenze kwihanganira bikomeye. Ikemura ingaruka. Mugihe OEM yu Burayi yari ikeneye gusimbuza pisitori ya piston pompe nyuma yicyiciro cyabatanga isoko yananiwe kwipimisha umunyu, twakoze ibizamini byihuse byangirika kubuvuzi butatu - amashanyarazi 316L, HVOF ikoreshwa na WC-Co, na duplex nitrid 17-4PH - hanyuma twohereza ama coupons yikizamini hamwe namakuru yamasaha 500. Umukiriya yahisemo nitriding. Ibice byo murwego ubu birenga amezi 24 mubihe bishyuha. Ibyo ntabwo ari ugukora. Nibyo kwimura ibyago-hamwe nibimenyetso.
Uruganda rukora neza cyane uruganda rutunganya ikizere ntirukurikirana urutonde, ahubwo mugukemura ibibazo abandi birinda. Kimwe no gutunganya mm-120 z'uburebure bwa cobalt alloy nozzle hamwe na 0.3-mm-yoroheje ya radiyo ya radiyo-aho guhinduranya ibikoresho bigomba kuguma munsi ya 3 µm cyangwa inguni ihinduka 0.8 °, bikabangamira imbaraga zitemba. Cyangwa kwemeza ko buri gice cyo gutoranya AMS 5387 gihura na ASTM A990 cyerekana ibintu * mbere yuko * CNC itangira - atari nyuma yo gusiba. Cyangwa gufata ± 0.008 mm kwihanganira imyanya kuri 16 yinjijwe mumutwe umwe wa pompe ya aluminiyumu - ukoresheje ibikoresho bya vacuum byabigenewe bikuraho igice mugihe cyo gukanda.
Niba umushinga wawe utaha usaba ibice bikomeza kubaho umuvuduko ukabije, kwambara cyane, cyangwa kwangirika kwinshi-utarinze gusubiramo ibizunguruka cyangwa kunanirwa mu murima - tangira ubikora, ntabwo ari geometrie gusa. Sura https://www.tsingtaocnc.com gusubiramo ubushobozi bwa tekiniki, gukuramo GD&T ubuyobozi bwiza bwimyitozo, cyangwa gutanga ibishushanyo kubitekerezo byubusa. Precision ntabwo isobanurwa na micrometero yonyine. Byasobanuwe nibinanirana-nibitagenda-iyo sisitemu ikora.
