Iyo abajenjeri bagaragaje icyuma cyumuhondo kumubiri wa hydraulic valve cyangwa amazu ya pompe, ntabwo bahitamo gusa ibikoresho-bahitamo gushikama kumurongo munsi yumuvuduko wa bar-300, kwambara kwihanganira nyuma yizunguruka 10,000, no kwihanganira zeru kugabanuka kwa mikorobe mu gutwara ibintu. Niyo mpamvu guhitamo iburyo uruganda rukora ibyuma ntabwo bijyanye nigiciro gito cyangwa igihe cyihuta cyo kuyobora. Byerekeranye no kugenzura metallurgical, disipuline yuburyo, no guhuza injeniyeri-ibintu bitatu twabonye byananiranye inshuro nyinshi iyo casting yimukiye hanze itabanje kugenzura tekiniki.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dukora imashini kandi tugatera ibyuma byumuhondo imvi buri munsi - ntabwo ari ibicuruzwa, ahubwo ni kwagura imikorere ya sisitemu yumuvuduko mwinshi. Itsinda ryacu ryashinzwe ntabwo rifata ASTM A48 Icyiciro 30B nkigisanduku. Turakurikirana grafite nodule ibara kuri mm², kugenzura ibiri muri pearlite dukoresheje metallografiya mbere yo kuvura ubushyuhe, kandi twemeza imbaraga zingana kuri buri kintu gisuka - ntabwo ari icyitegererezo gusa. Kubera iki? Kuberako piston pompe ya silinderi ifite 12% ya pearlite aho kuba 85-92% birananirana hakiri kare mumagare yubushyuhe. Twarabibonye. Kandi twubatse inzira yacu kugirango tuyirinde.
Ikitandukanya uruganda rukora ibyuma byizewe nicyuma gitanga ibicuruzwa ni uguhuza vertical - ntabwo ari mubikoresho gusa, ahubwo no mubuyobozi bufata ibyemezo. Ku kigo cacu cyemewe na ISO muri Qingdao, injeniyeri umwe wemeza ibyemezo fatizo na we asinya kuri raporo ya CMM ya nyuma yo guhamagara GD&T nka Ø42.5 ± 0.015 mm hamwe no kwihanganira imyanya 0,05 mm ugereranije na datum A-B-C. Nta ntoki. Nta gihombo cyubuhinduzi hagati yo gushushanya no gutunganya imashini. Mugihe umukiriya yohereje igishushanyo cya winch center shaft roller hamwe na 60 ° byahagaritswe, itsinda ryacu rikoresha uburyo bwo kwigana * mbere yo kwemeza icyitegererezo - kandi ibendera rishobora guteza ibyago byo gutera ubwoba muri zone ya meshi. Ntabwo ari "inkunga." Nibisangiwe nyirubwite imikorere ikora.
- Gukurikirana ibintu bitangirira ku itanura - ntabwo ari ubwato. Buri cyuma gisize icyuma gitwara ubushyuhe bujyanye no gusesengura ibintu, ibipimo byo gukonjesha, hamwe no gushushanya ibice bikomeye.
- Nta buryo busanzwe bwo gutunganya umucanga. Dukoresha ibishushanyo bisobekeranye kububiko bwurukuta ruto (mm 2,8 mm byibuze), umucanga wicyatsi kubishingwe binini (> 120 kg), kandi tugenzura igipimo cyo gukonjesha kuri flanges zikomeye - ntabwo ari rimwe-rimwe-byose.
- Imashini ntabwo isukurwa nyuma-ni indishyi zuzuye. Turahanagura kugabanuka kugabanuka (0,72% kuri HT250), gukosora kugoreka ibicu mubice byinshi byashizwemo, hamwe no kongera gukora imashini itwara bore nyuma yo kugabanya imihangayiko kugirango ifate uruziga muri mm 0.008.
Abaguzi bamwe bibwira ko icyuma cyijimye ari “cyoroshye.” Ariko ibintu bigoye byihishe muburyo burambuye: Nigute uwaguhaye isoko akemura amacakubiri ya sulferi mubice biremereye? Bapima igipimo cya ferrite / pearlite - cyangwa bakavuga gusa ubukana bwa Brinell? Bashobora gufata 0,02 mm hejuru yuburebure bwa mm 450 × 320 hejuru yo kudasya? Twagize abakiriya baduhindukirira nyuma yo kugemura bitatu byananiranye kubacuruzi batsinze igenzura-ariko bagatanga ibice hamwe na flotation yo munsi y'ubutaka ya grafite yamenetse mugihe cyo gupima hydraulic kuri 220 bar. Gukosora ntibyari byiza QC. Byarushijeho kugenzura ubushyuhe bwo gusuka (1380–1410 ° C), igihe cyo gutera (mu masegonda 20 nyuma yo gukanda), hamwe no guhumeka neza. Ibi ntabwo ari ibisobanuro kuri datasheet. Bimenyerewe injyana.
Kubikorwa byingenzi-bigizwe na pompe yamavuta ya peteroli, moteri ya crane hydraulic manifolds, marine bilge sisitemu yo mu ruganda - uruganda rwawe rukora ibyuma rugomba gukorera kumasangano ya metallurgie, geometrie, hamwe nuburemere bwisi. Ibyo bivuze kwemeza ibishushanyo mbonera byerekana ibipimo bifatika * kuri buri bushyuhe *, ukoresheje imashini zipima ibipimo-bitari Calipers-kugirango bigenzurwe bwa nyuma, kandi bifite ibisobanuro byuzuye kuva kumurongo kugeza kubyoherejwe. Bisobanura gusobanukirwa ko amazu ya AMS 5387 cobalt alloy amazu asangiye ibikoresho kimwe na protocole yo gucunga amashyanyarazi kimwe na bagenzi babo b'icyuma - kuko gutembera kurwego bigira ingaruka zombi kimwe. Bisobanura kuvuga "oya" mugihe cyibitero mugihe icyitegererezo cyo gushimangira cyerekana ingaruka - no gutanga ubundi buryo bwemewe aho gusezerana.
Niba ukeneye icyuma cyumukara kibaho imyaka 15 mumazi yumunyu winyanja cyangwa kugumana ubunyangamugayo nyuma yikigereranyo cyingutu 50.000, tangira ukoresheje gukorera mu mucyo - ntabwo ari numero ya catalog. Reba inyandiko zerekana ubugenzuzi, ntabwo ari ibyemezo gusa. Menya neza ko "precision" ikubiyemo microstructure igenzura, ntabwo yihanganira gusa. Kandi wibuke: gukina bihenze cyane ntabwo aribyo bifite igiciro kinini. Nibidindiza gutangiza, bikurura ibikorwa byo murwego, cyangwa guhungabanya umutekano wa sisitemu. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka ibara ryicyuma aho kunanirwa atari amahitamo-kubwizerwa rero ntabwo arikintu. Nibyingenzi.
