Akatswiri akamanena za kuponyedwa kwachitsulo chotuwa kwa mavavu opangidwa ndi ma hydraulic okwera kwambiri kapena ma pump housings, samangosankha chinthu—akubetcherana pa kukhazikika kwapang'onopang'ono pansi pa matenthedwe apanjinga, kugawa kosasinthasintha kwa ma graphite flake potentha kwambiri, komanso kukhulupirika kwapamtunda pambuyo pa makina. Chifukwa chake kusankha koyenera kampani yopanga chitsulo chotuwira sizikunena za mabulosha kapena ziphaso zokha. Zimakhudza machitidwe otsimikiziridwa pakupanga zenizeni zapadziko lapansi: momwe maziko amagwirira ntchito kutentha kwa kutentha pakusintha kwa maola 72, ngakhale zipika zake zamchenga zophatikizika zimatsatiridwa pagawo lililonse loponyera, ndipo ngati shopu yake ya CNC imatha kusunga ± 0.015 mm pa 320 mm bore-*pambuyo* mpumulo wopsinjika.
Tawona mapulojekiti ambiri akuyimitsidwa chifukwa wogulitsa amawona chitsulo chotuwa ngati "chitsulo chongoponyedwa" - kunyalanyaza momwe kusiyanasiyana pang'ono kwa mpweya wofanana ndi mpweya (CE), kuzizira, kapena kugwedeza nthawi kumakhudzira kusinthika kwa ma cylinder bores kapena malo osindikiza otayira. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Iron imvi si chinthu. Ndi dongosolo lazitsulo lolamulidwa. Mawonekedwe awo a QT450-10 ndi GG25 amawunikiridwa * asanatsanulidwe, ndipo CE imakhala mkati mwa ± 0.08 mfundo pamagulu onse. Kutentha kulikonse kumakhala ndi kuwunika kokwanira: chipika chosungunuka, nambala ya ladle, ID ya nkhungu, ndi kutsimikizira kulimba kwa Brinell pambuyo pa kutentha - osati satifiketi yosindikizidwa "yogwirizana."
Mphamvu zawo zagona pakuphatikizana koyima - osati ngati mawu, koma monga kuwongolera. Nyumba ya silinda ya pampu ya pisitoni imayamba ngati GG25 yopanda mchenga, kenako imasunthira molunjika ku malo awo a ISO 9001-certified CNC pansi popanda mayendedwe apakatikati. Palibenso zodabwitsa zodabwitsa. Palibe kusalumikizana bwino kwamakina pakati pa datum ndi makina opangira makina. Amagwiritsa ntchito makina osindikizira ofunikira pakukhazikitsa kumodzi, pogwiritsa ntchito zida za Renishaw-probed kuti athe kubwezera kuuma kwapafupi. Umu ndi momwe amaperekera kumaliza kwa 0.4 µm Ra pampando wa ma valve - osapumira pang'ono - ndikusunga kukhazikika kwa 0.02 mm pakati pa bore ndi flange yokwera pamtunda wa 120 mm. Makasitomala ku North America akuwonetsa kuti 30% yachulukira pang'ono pamapampu olowa m'malo motsutsana ndi omwe adaperekapo kale - chifukwa mawonekedwe ang'onoang'ono omwe akuponyawo sanakakamize makina ankhanza omwe adawonetsa porosity yapansi panthaka.
Koma kuphatikiza kumatanthauza pang'ono popanda kuzama kwaukadaulo mumayendedwe a aloyi. Chitsulo chotuwira sichinadzipatula pano - chimapangidwa pamodzi ndi makina a cobalt-nickel. Pamene kasitomala akufunikira msonkhano wosakanizidwa-titi, maziko a mpope a GG25 okhala ndi ma valve a AMS 5387 a cobalt alloy - gulu lomwelo limagwira zonse ziwiri. Amadziwa kuti T800's kukulitsa kwamafuta kowonjezera ndi 37% kutsika kuposa chitsulo chotuwira, kotero amapanga zosokoneza komanso zozungulira zomwe zimalepheretsa kusweka kwa nkhope panthawi yantchito pa 220 ° C. Kulankhula bwino kwazinthu izi ndikofunikira: kumalepheretsa kukonzanso kokwera mtengo pamene kusagwirizana kwamafuta kumayambitsa kulephera kwa gasket nthawi isanakwane kapena kuvala kovutirapo pamphambano. Tidawawona akusintha ma graphite morphology pogwiritsa ntchito inoculant nthawi kuti apititse patsogolo kunyowa kwa ma winch center shaft rollers-kuchepetsa kufalikira kwa vibration ndi 42% pamayeso am'munda pamagalimoto oyendetsa magalimoto.
Kodi chimawalekanitsa ndi chiyani kwa ogulitsa makatalogu? Nthawi yoyankhira pa mayankho akupanga. Tumizani chojambula cholemera cha GD&T cha valavu yamagetsi, ndipo mupeza ma PDF odziwika mkati mwa maola 48 - osati zolemba zamtundu uliwonse ngati "kulekerera kolimba," koma mawu omveka bwino: "Datum C iyenera kusuntha 0.3 mm kupita ku axis yoboola kuti isasokoneze magudumu," kapena "Kutchula Rz m'malo mwa Kubwereza apa kumapangitsanso mtengo wosindikiza popanda kusindikiza." Protocol yawo yabwino siimayendetsedwa ndi mndandanda; ndizopanga mapu owopsa. Zopangira zomwe zikubwera zimapeza kusanthula kwa spark emission * ndi * kuyesa kwa akupanga pakuchepa kwamkati. Macheke akamagwiritsidwa ntchito amagwiritsa ntchito ma Zeiss CMM okhala ndi masitayelo a ceramic okhazikika, osati ndodo za aluminiyamu - kotero kuti kutenthedwa kwa kutentha sikusokoneze zotsatira pa 20 ° C mozungulira. Kuyang'anira komaliza kumaphatikizapo kuyesa kukakamiza kwa 1.5 × kugwira ntchito, ndikutsimikizira kolowera kwa utoto wamitundu yonse yamakina.
Ngati dongosolo lanu lotsatira la chitsulo chotuwa likufuna zambiri kuposa "zokwanira ndipo sizikusweka," yang'anani umboni wowongolera njira - osati kungotsatira. Yang'anani masitolo omwe akatswiri azitsulo amawunikira malipoti ogawa mchenga musanapange nkhungu, kumene opanga mapulogalamu a CNC amasintha mitengo ya chakudya potengera kuuma kwa nthawi yeniyeni ya kuponyedwa kulikonse, ndi kumene masiku operekera amakhazikika pazitsulo zozungulira ng'anjo-osati malonjezo ogulitsa. Ndicho chenicheni chogwira ntchito kumbuyo kwa zigawo zodalirika zolondola. Pazinthu zofunikira pama hydraulics, mafuta & gasi, kapena makina amagalimoto olemera, kusasinthika sikungasankhe. Ndiko kusiyana pakati pa kukonza kwadongosolo ndi nthawi yosakonzekera.
