HT250 cast iron sigiredi inanso pa datasheet-ndi msana wa ma hydraulic manifolds, mapampu, ndi mafelemu a winch system omwe amayenera kukhala okhazikika pansi pa 350 bar pressure cycle. Pamene kasitomala ku Germany anatitumizira chithunzi cha nyumba ya silinda ya pampu ya piston—HT250, ±0.02 mm GD&T callouts, pamwamba Ra 1.6 µm—sitinayambe ndi mawu. Tinayamba ndi kutsimikizira kwazitsulo: kutsimikizira kufanana kwa kaboni (CE = 4.12), kutsimikizira zomwe zili ndi pearlite ≥85% kudzera kusanthula kwa micrograph, ndikuwunika kuuma kwa Brinell kumadera atatu (192-208 HBW). Ndi momwe a Chithunzi cha HT250 amapeza chidaliro—osati mwa kundandalitsa ziphaso, koma mwa kuchirikiza chosankha chirichonse m’khalidwe lakuthupi.
Chifukwa chiyani HT250 Imafunikira Zambiri Kuposa Zochita Zoyambira Zokhazikika
Ogulitsa ambiri amawona HT250 ngati "chitsulo chotuwira." Koma njira zenizeni zolephera zimanena nkhani yosiyana. Tawonapo nyumba za silinda zikuphwanyidwa pamalumikizidwe a flange pambuyo pa maola ogwirira ntchito a 14,000-osati kuchokera pakuchulukirachulukira, koma kuchokera kugawa kosagwirizana ndi ma graphite nodule panthawi yolimba. Nthawi ina, wopanga zida zamafuta aku North America adakana 12% ya batch chifukwa magulu olemera a ferrite adapanga pafupi ndi zipsepse zoziziritsa, kutsitsa mphamvu zakumaloko pansi pa 250 MPa. Chifukwa chake Chithunzi cha HT250 imayang'anira mitundu isanu ndi umodzi yofunikira isanatsanulidwe: kutentha kwasungunuka (1,480-1,510 ° C), nthawi ya inoculation (mkati mwa masekondi 90 pambuyo pogogoda), nthawi yokhala ndi ladle (<4 mphindi), compaction mold (≥120 kPa), kuwongolera kuziziritsa (palibe kukakamiza kokakamiza pafupi ndi magawo ovuta), komanso mpumulo wa post-cast stress (550 ° C / 4 hrs + ng'anjo yozizira). Palibe njira zazifupi. Ayi "zabwino".
Kuphatikiza Koyima Kumathetsa Zomwe Kutulutsa Kwakunja Kumaswa
Ena ogula gwero akuponya kuchokera wogulitsa, Machining wina, kutentha mankhwala kwa lachitatu. Mtundu umenewo umalephera HT250. Chifukwa chiyani? Chifukwa kupsinjika kotsalira kopangidwa ndi makina kumalumikizana mosayembekezereka ndi as-cast microstructure. Tidayezera kupotoza kwa 45 µm m'matupi opangidwa ndi makina a HT250 pomwe kukonza ndi kumaliza kunachitika m'malo osiyanasiyana - ngakhale ndi zida zofanana. Pamalo athu, kuponyera, kuchepetsa nkhawa, kukonza makina a CNC, ndikuwunika komaliza kumachitika pansi pa denga limodzi. Timagwiritsa ntchito CMM yomweyo potsimikizira zomwe zikubwera komanso kusaina komaliza-kuchotsa zolakwika zakusintha kwa data. Pa dongosolo laposachedwa la makina opangira ma winch center shaft rollers, kuphatikiza kumeneku kunachepetsa nthawi yotsogolera ndi 37% ndikuchepetsa kukana nkhani yoyamba kuchoka pa 11% kufika paziro. Kusiyana sikunali makina othamanga. Zinali zoyendetsedwa ndi mbiri yamafuta ndi metrology yolumikizana.
Magwiridwe Adziko lenileni a HT250 Amayamba Ndi Chilango cha Zakuthupi
"Chitsimikizo cha HT250" sichitanthauza kanthu popanda kufufuza. Timakana zosungunula zochokera kuzinthu zofunikira kwambiri. Kuthira kulikonse kwa HT250 kumagwiritsa ntchito ≥75% chitsulo cha nkhumba chamwali (kuchokera ku zitsulo zotsimikizika zaku China ndi Korea), coke ya sulfure yochepa (<0.3% S), ndi ferrosilicon inoculants ndi ≤0.02% aluminiyamu. Kutentha kulikonse kumakhala ndi lipoti lathunthu - kaboni, silicon, manganese, sulfure, phosphorous, chromium, molybdenum - ndipo timasunga ma micrograph a digito pagawo lililonse. Pamene pompu yaku Southeast Asia OEM imafunikira magawo a AMS 5387 cobalt alloy * ndi * HT250 maziko a msonkhano womwewo, tidafananiza ma coefficients owonjezera amafuta pazida zonse ziwiri - osati mongoyerekeza, koma poyesa mayeso ofanana a dilatometry. Umu ndi momwe umphumphu wogwira ntchito umapangidwira mu ndondomeko-osati kuwonjezeredwa pambuyo pake.
Kusankha Fakitale Yanu ya HT250: Macheke Atatu Osakambirana
- Funsani malipoti a microstructure-osati manambala olimba. Wogulitsa weniweni wa HT250 amakuwonetsani pearlite %, mtundu wa graphite (A-E pa ASTM A247), ndi masitayilo apakati-osati "kungokumana ndi ISO 185."
- Pamafunika umboni wa in-process dimensional control. Ngati angoyeza zigawo zomwe zatsirizidwa, funsani komwe amawona kucheperachepera panthawi yozizirira. Timalemba kutentha kwa bokosi lapakati, chinyezi cha nkhungu, ndi data yoziziritsa pakupanga kulikonse.
- Tsimikizirani kuthekera kwa GD&T pamalo oponyedwa. Kodi CMM yawo ingafufuze zamtundu wa datum? Kodi amagwiritsa ntchito ma comparator owoneka pazambiri zovuta? Timatsimikizira zoperekera zotsutsana ndi CAD tisanapange makina - chifukwa kukonzanso pa HT250 kumawononga 3.2 × kuposa pazitsulo.
An Chithunzi cha HT250 sichimatanthauzidwa ndi kapolo kapena mzere wake. Zimatanthauzidwa ndi momwe zimayankhira mafunso okhudza graphite morphology, momwe zimagwirira ntchito kulekerera kwa 0.05 mm pa 400 mm kuponyera, komanso ngati zimatengera zojambula zanu monga mgwirizano wopanga-kapena poyambira kukambirana zaumisiri. Sititumiza magawo a HT250. Timatumiza mayendedwe otsimikizika -kuchokera kuzitsulo zosungunuka kupita ku ntchito zopanikizika. Ndilo metric yokha yomwe imafunikira ngati kulephera sikungatheke.
