Iyo abajenjeri bagaragaje ibyuma bikozwe mu cyuma cya hydraulic gifite inshingano nyinshi cyangwa amazu ya pompe, ntabwo bahitamo gusa ibikoresho-bahitamo gushikama kurwego rwo munsi yumukino wo gusiganwa ku magare, gukwirakwiza grake ya flake ikwirakwizwa nubushyuhe, hamwe nubusugire bwubutaka nyuma yo kubitunganya. Niyo mpamvu guhitamo iburyo uruganda rukora ibyuma ntabwo ari udutabo cyangwa ibyemezo byonyine. Byerekeranye nimyitwarire yagaragaye mubikorwa nyabyo-byukuri: uburyo uruganda rukora uruganda rusuka ubushyuhe mugihe cyamasaha 72, niba ibiti byacyo byo guhuza amakuru byumucanga bishobora gukurikiranwa kuri buri gice cyo guteramo, kandi niba iduka ryacyo rya CNC rishobora gufata ± 0.015 mm kuri 320 mm ya bore - * nyuma * yo kugabanuka.
Twabonye imishinga myinshi ihagaze kubera ko uwatanze isoko yafataga icyuma cyijimye nk "icyuma gusa" - byerekana uburyo itandukaniro rito muri karuboni ihwanye na CE (CE), igipimo cyo gukonjesha, cyangwa igihe cyo guhungabana bigira ingaruka kumashanyarazi ya bore ya silinderi cyangwa inzira zifunga inzira. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Icyuma cyijimye ntabwo ari ibicuruzwa. Nuburyo bugenzurwa na metallurgjique. Abakinnyi babo ba QT450-10 na GG25 bakorerwa isesengura ryerekanwa * mbere yo gusuka, hamwe na CE ifite amanota ± 0.08 mubice byose. Buri bushyuhe butwara ibisobanuro byuzuye: gushonga ibiti, nimero ya salle, indangamuntu ya mold, hamwe na nyuma yo kuvura ubushyuhe bwa Brinell - ntabwo ari icyemezo cyashyizweho kashe "gihuza."
Imbaraga zabo ziri muburyo bwo guhuza - ntabwo ari ijambo ryijambo, ahubwo ni indero yimikorere. Inzu ya pisitori ya piston itangira nkumucanga GG25 irimo ubusa, hanyuma ikimukira mu igorofa ryabo rya ISO 9001 ryemewe na CNC ridafite aho rinyura. Nta kongera gutungurana. Nta guhuza sisitemu itandukanye hagati yo guta datum no gutunganya ibikoresho. Bakora imashini ikomeye yo gufunga mumaso muburyo bumwe, bakoresheje ibikoresho bya Renishaw bigenzurwa kugirango bishyure ibyuma bikomakomeye. Nuburyo batanga 0.4 µm Ra kurangiza kubutaka bwa valve-nta gukubita inshuro ya kabiri-kandi bagakomeza kwibanda kuri mm 0,02 hagati ya bore na mount flange hejuru ya mm 120 z'uburebure. Abakiriya bo muri Amerika ya Ruguru bavuga ko 30% ari bike mu myanda yamenetse ku mazu asimburwa n’abatanga ibicuruzwa mbere - kubera ko microstructure ya casting itigeze ihatira imashini zikaze zerekanaga ububi bwo munsi.
Ariko kwishyira hamwe bivuze bike bidafite ubuhanga bwa tekinike mumyitwarire ya alloy. Icyuma kijimye ntigishobora kwigunga hano-cyakozwe hamwe na sisitemu ya cobalt-nikel. Iyo umukiriya akeneye inteko ya Hybrid-vuga, fondasiyo ya pompe ya GG25 hamwe na AMS 5387 cobalt alloy valve yinjizamo - itsinda rimwe rikemura byombi. Bazi ko coefficient ya T800 yo kwagura ubushyuhe iri munsi ya 37% ugereranije nicyuma cyumuhondo, bityo bagashushanya guhuza kwizunguruka hamwe na annealing cycle birinda gucikamo intera mugihe cya serivisi kuri 220 ° C. Uku gutondeka ibintu bifatika: birinda kongera kugiciro cyinshi mugihe kudahuza ubushyuhe bitera kunanirwa gasketi imburagihe cyangwa kwambara nabi. Twabarebye bahindura imiterere ya grafite ikoresheje igihe cyo kudatezimbere kugirango tunonosore neza muri winch center shaft rollers - kugabanya ihererekanyabubasha rya 42% mubizamini byo murwego rwo gutwara ibinyabiziga.
Niki kibatandukanya nabacuruzi ba catalog? Igihe cyo gusubiza kubitekerezo byakozwe. Kohereza igishushanyo cya GD & T kiremereye kumubiri wa valve, hanyuma uzabona PDF zisobanuwe mumasaha 48 - ntabwo ari inyandiko rusange nka "kwihanganira gukomeye birashoboka," ariko guhamagarwa kwihariye: "Datum C igomba guhindura mm 0.3 yerekeza kuri bore axis kugirango wirinde gusya uruziga," cyangwa "Kugaragaza Rz aho kuba Ra hano bizamura kugumana kashe utongeyeho ikiguzi." Porotokole yabo nziza ntabwo igenzurwa na lisiti; ni ikarita. Ibikoresho byinjira byinjira bisohora ibyuka byangiza * na * ultrasonic kwipimisha kugabanuka imbere. Igenzura-mugikorwa ukoreshe Zeiss CMMs hamwe na kalibateri ceramic styli-ntabwo ari inkoni ya aluminium-bityo rero gutwarwa nubushyuhe ntibishobora kugabanya ibisubizo kuri 20 ° C. Igenzura ryanyuma ririmo gupima imikorere ikora kuri 1.5 pressure igitutu cyakazi, hamwe no kugenzura irangi-ryuzuye ryuzuye ryimashini.
Niba icyuma cyawe gikurikiraho cyicyuma gisaba ibirenze "birahuye kandi ntibisenyuka," shakisha ibimenyetso byerekana uburyo bwo kugenzura ibintu - ntabwo byubahirizwa gusa. Shakisha amaduka aho metallurgiste asubiramo raporo yo gukwirakwiza umucanga mbere yo gukora ibumba, aho abategura porogaramu ya CNC bahindura igipimo cyibiryo bishingiye ku ikarita nyayo yo gushushanya buri gihe, kandi aho amatariki yatanzwe ashyirwa ku ziko ry’ibiti - ntabwo ari amasezerano yo kugurisha. Nibyo byukuri bikora inyuma yibice byizewe. Kubisaba gusaba muri hydraulics, peteroli & gaze, cyangwa sisitemu yimodoka iremereye, ibyo guhuzagurika ntabwo ari ubushake. Ni itandukaniro riri hagati yo kubungabunga no guteganya igihe.
