Akatswiri akamanena za kuponyedwa kwachitsulo chotuwira kwa matupi a hydraulic valves kapena mapampu, samangosankha chinthu - akubetcha pamlingo wokhazikika pansi pa 300-bar pressure, amavala kukana pambuyo 10,000 opareshoni, ndi zero kulolerana kwa micro-shrinkage mu flanges zonyamula katundu. Chifukwa chake kusankha koyenera imvi chitsulo kuponyera fakitale sichimakhudza mtengo wotsika kwambiri kapena nthawi yofulumira kwambiri. Ndizokhudza kuwongolera zitsulo, kuwongolera njira, ndi kugwirizanitsa uinjiniya-zinthu zitatu zomwe taziwona zikulephera mobwerezabwereza pamene oponya amapita kumtunda popanda kuyang'anira luso lokhazikika.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timapanga makina ndikuponyera zigawo zachitsulo zotuwa tsiku ndi tsiku-osati ngati zinthu, koma monga zowonjezera zogwira ntchito zamakina apamwamba kwambiri. Gulu lathu loyambitsa silitenga ASTM A48 Class 30B ngati bokosi. Timatsata kuchuluka kwa ma graphite nodule pa mm², kutsimikizira zomwe zili mu pearlite kudzera muzitsulo zamagetsi tisanatenthedwe, ndikutsimikizira kulimba kwapang'onopang'ono pa ladle iliyonse—osati zitsanzo chabe. Chifukwa chiyani? Chifukwa nyumba ya silinda ya pampu ya pistoni yokhala ndi 12% pearlite m'malo mwa 85-92% imalephera msanga poyendetsa njinga yamoto. Taziwona. Ndipo tinapanga ndondomeko yathu kuti tipewe.
Chomwe chimalekanitsa fakitale yodalirika yopangira chitsulo chotungira kuchokera kwa ogulitsa ndikuphatikizana molunjika - osati pazida zokha, koma muulamuliro wopanga zisankho. Pamalo athu ovomerezeka a ISO ku Qingdao, mainjiniya yemweyo yemwe amavomereza ma cert osaphika amasainanso malipoti omaliza a CMM a GD&T callouts ngati Ø42.5±0.015 mm yokhala ndi kulolerana kwa 0.05 mm poyerekeza ndi datum A-B-C. Palibe ma handoffs. Palibe kutayika komasulira pakati pa kapangidwe kake ndi kuyika makina. Makasitomala akatumiza chojambula cha winch center shaft roller yokhala ndi 60° helical grooves, gulu lathu limapanga zofananira *zisadavomerezedwe* ndi ziwopsezo zoyika mbendera zomwe zingayambitse kulimba kwa ma mesh zone. Izi si "thandizo". Imagawana umwini wa magwiridwe antchito.
- Kufufuza kwazinthu kumayambira pa ng'anjo - osati pokokera. Chitsulo chilichonse chotuwa chimakhala ndi nambala ya kutentha yolumikizidwa ndi kusanthula kwazithunzi, mitengo yozizirira, komanso kulimba kwa mapu m'magawo ovuta.
- Palibe "standard" mchenga nkhungu ndondomeko. Timagwiritsa ntchito nkhungu zomangira utomoni m'zipinda zoonda (zochepera 2.8 mm), mchenga wobiriwira pamaziko akulu (> 120 kg), komanso kuziziritsa kozizira kwa ma flanges ovuta kupsinjika - osakwanira kukula kumodzi.
- Machining si kuyeretsa pambuyo-ndikulipira mwatsatanetsatane. Timachotsa kutsika kodziwikiratu (0.72% ya HT250), kuwongolera kupotoza kwa nkhungu m'magawo ang'onoang'ono, ndikubwezeretsanso makina okhala ndi ziboliboli pambuyo pochepetsa kupsinjika kuti tigwire mozungulira mkati mwa 0.008 mm.
Ogula ena amaganiza kuti chitsulo chotuwira ndi "chosavuta." Koma zovuta zimabisala mwatsatanetsatane: Kodi wothandizira wanu amachita bwanji ndi tsankho la sulfure m'magawo olemetsa? Kodi amayesa chiŵerengero cha ferrite/pearlite-kapena amangonena kuuma kwa Brinell? Kodi amatha kukhala ndi 0.02 mm flatness pamtunda wa 450 × 320 mm popanda kugaya? Takhala ndi makasitomala osinthira kwa ife atalephera kubweretsa katatu kuchokera kwa ogulitsa omwe adadutsa kuyang'ana kowoneka - koma adapereka magawo okhala ndi graphite flotation yomwe idasweka pakuyesa ma hydraulic pa bar 220. Kukonzekera sikunali bwino QC. Kunali kuwongolera kwambiri kutentha kothira (1380-1410 ° C), nthawi yothira (mkati mwa masekondi 20 kuchokera pakugwira), komanso kusasinthasintha kwa kutentha kwa nkhungu. Izi sizomwe zili patsamba. Iwo amapangidwa rhythms.
Pazinthu zofunikira kwambiri - mafelemu a pampu akumunda wamafuta, makina opangira ma crane hydraulic manifolds, mavavu am'madzi am'madzi - fakitale yanu yopangira chitsulo chotuwira iyenera kugwira ntchito pamphambano zazitsulo, geometry, ndi kutsitsa kwenikweni. Izi zikutanthawuza kutsimikizira kayesedwe kake poyesa mipiringidzo ya thupi * pa kutentha kulikonse *, kugwiritsa ntchito makina oyezera ogwirizana - osati ma caliper - kuti awonenso komaliza, ndikusunga kutsata kwathunthu kuchokera pa ladle kupita kutumizidwa. Zimatanthawuza kumvetsetsa kuti nyumba za AMS 5387 cobalt alloy zimagawana makina amakina omwewo komanso ma protocol oyang'anira matenthedwe monga anzawo achitsulo chotuwa - chifukwa kugwedezeka kumakhudza zonse mofanana. Zimatanthawuza kunena kuti "ayi" ku nthawi zaukali pamene kukhazikika kwachitsanzo kukuwonetsa chiopsezo - ndikupereka njira ina yovomerezeka m'malo mwa lonjezo.
Ngati mukufuna zitsulo zotuwa zomwe zimatha zaka 15 m'madzi amchere amchere kapena kusunga umphumphu pambuyo pa kukakamiza kwa 50,000, yambani ndikuwonetsa poyera - osati manambala amndandanda. Yang'anani ndondomeko zoyendera zolembedwa, osati ziphaso zokha. Tsimikizirani kuti "kulondola" kumaphatikizapo kuwongolera kwa microstructure, osati kulolerana kolimba. Ndipo kumbukirani: okwera mtengo kwambiri si omwe ali ndi mtengo wapamwamba kwambiri. Ndilo lomwe limachedwetsa kutumidwa, kumayambitsa kukonzanso m'munda, kapena kusokoneza chitetezo chadongosolo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imapanga zida zachitsulo zotuwa pomwe kulephera sikungatheke - kotero kudalirika sizinthu. Ndilo maziko.
