Otsatsa fakitale a QT400-18 samangotumiza zojambula zokha - amapereka chidaliro chokhazikika. Pamene manifold anu a hydraulic ayenera kukhala ndi 350 bar, pomwe shaft yanu ya winchi imapirira kugwedezeka kwatsiku ndi tsiku ku Arctic kunyanja, kapena nyumba yapampu ikayang'anizana ndi slurry ya 120 ° C, chitsulo cha ductile si mawu am'munsi. Ndi maziko. QT400-18 si generic imvi chitsulo. Ndiwopangidwa molimba, spheroidal graphite microstructure yokhala ndi mphamvu yocheperako ya 400 MPa ndi kutalika kwa 18% - mphamvu yosowa, ductility, ndi machinability zomwe zoyambira zochepa zimakwaniritsa kukula kwa batch kuchokera ku 5 mpaka 500 mayunitsi.
Chifukwa chiyani QT400-18 imalephera - osati mu labu, koma pansi pa sitolo
Tawona mitundu itatu yolephera mobwerezabwereza m'mapulogalamu adziko lapansi a QT400-18: kuwerengera kosasinthika kwa nodule pansi pa 120/mm², chiŵerengero cha ferrite/pearlite chikupitilira kupitirira 85/15%, ndi tsamba lankhondo lotsalira lomwe limapangitsa kupsinjika mtima pambuyo pomaliza CNC. Izi sizowopsa zongoyerekeza. Amawoneka ngati ming'alu ya kutopa msanga m'nyumba za silinda ya pampu ya piston, monga momwe zimabowolerera m'matupi okakamiza a valve, kapena kung'amba pang'ono poyang'ana. Chifukwa chake? Zambiri za "QT400-18" pa intaneti zimangonena za chemistry - osati kuwongolera kwenikweni. Kutsatira kwenikweni kumafuna kuwongolera kokhazikika pa nthawi ya chithandizo cha magnesiamu, kutentha kwa katemera, kuzizira mu nkhungu, komanso kuwongolera kwapambuyo kupsinjika. Pamalo athu a Qingdao, kutentha kulikonse kwa QT400-18 kumayesedwa kowoneka bwino, kutsimikizika kwa nodule morphology kudzera pa ASTM E2399, ndikuyezetsa kolimba pa ISO 6892-1 - osati pamipiringidzo yoyesera, koma makuponi oyimira odulidwa kuchokera pagawo lokhuthala kwambiri la kuponya.
Kuphatikiza koyima kumathetsa zomwe masamba amabisala
Ogula ambiri amachokera ku QT400-18 kuchokera kwa ogulitsa m'modzi ndikumaliza kwina. Kulumikizana koteroko kumapanga madontho akhungu. Timasindikiza gawo lililonse la QT400-18 m'nyumba - titangothetsa kupsinjika, kugwedezeka kusanayambe. Maselo athu a CNC okhala ndi ma axis asanu amadula mwachindunji kuchokera ku mchenga wobiriwira pogwiritsa ntchito zida za carbide zokongoletsedwa ndi chitsulo cha ferritic ductile. N’chifukwa chiyani zimenezi zili zofunika? Chifukwa kupanga makina a QT400-18 popanda kuwerengera gawo lake la 12-15% la graphite kumayambitsa macheza, kung'ambika m'mphepete, ndi kung'ambika pang'ono. Timasintha mitengo ya chakudya ndi 18% kutsika kuposa magawo achitsulo wamba ndipo timagwiritsa ntchito milomo yoziziritsira yomwe ili mkati mwa 12 mm wa zone yodulira. Zotsatira: Ra roughness pamwamba pa Ra ≤ 0.8 μm pa malo ovuta osindikizira, zero rework on bore concentricity for hydraulic spool valves.
Kutsata si zolemba - ndi physics
Pamene kasitomala ku Germany adanena za kuvala mosayembekezereka pa maziko a pampu a QT400-18, sitinayang'ane nkhaniyi osati kuponyedwa-koma ku makina ozizira ozizira omwe amatsika pansi pa 7.2% panthawi ya sabata. Kutsata kwathunthu kumatanthawuza kulumikiza gawo lililonse ndi nambala yake ya kutentha kwa zinthu zopangira, chizindikiro cha ng'anjo yamoto, curve yochepetsera kupsinjika, lipoti loyendera CMM, komanso batchi yozizirira yomwe imagwiritsidwa ntchito pomaliza. Timalemba zonsezi - osati mu Excel, koma mu ISO 9001-certified MES yathu, yokhala ndi siginecha ya digito pamalo aliwonse ofufuza. Palibe zojambula "monga-zomangidwa". Kukula kulikonse kumatsimikiziridwa motsutsana ndi ma callout a GD&T pogwiritsa ntchito ma Zeiss CONTURA G2 CMM osinthidwa kukhala miyezo ya NIST. Ngati chojambula chanu chikuwonetsa kulolera kwa Ø0.05 mm pamtundu wa bawuti wa flange, lipoti lathu lankhani yoyamba likuwonetsa kupatuka kwenikweni: Ø0.032 mm—kuyezedwa, kutsimikiziridwa, kusungidwa.
Ntchito yanu ya QT400-18 imayamba musanayitanitse
Sitinatchule ma castings. Timapanga ma co-engineer solutions. Mukatumiza chitsanzo cha CAD cha thupi la valve yothamanga kwambiri, akatswiri athu a metallurgists amayang'ana kusintha kwa makulidwe a khoma kuti awonongeke. Makina athu amawombera pansi pamasinthidwe omwe amafunikira zida zamachitidwe. Gulu lathu labwino limapereka zowunikira zogwirizana ndi zofunikira za ASME B16.34-osati kokha komwe ndikosavuta kuyeza, koma komwe kulephera kumachitika. Kota yatha, tidapanganso makina a kasitomala a QT400-18 kuti athetse utali wa 22 mm fillet womwe udapangitsa kuti porosity iwonongeke. Kuwongolera kosinthidwako kunachepetsa zinyalala kuchokera pa 14% mpaka 2.3%. Palibe chizindikiro. Kungogwira ntchito mokhulupirika, kuperekedwa.
Ngati mukufuna makina a QT400-18 omwe amachita-osati kungoyendera - funsani QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. mwachindunji. Timapanga magawo a QT400-18 a ma hydraulic system, magalimoto a engineering, zida zamafuta ndi gasi, ndi misonkhano yapadera yapampope - motsogozedwa ndi zonse, kutsata kwathunthu, komanso kuyankha kwathunthu. Pitani https://www.tsingtaocnc.com kuti muwunikenso mawu athu apano a QT400-18, certification zakuthupi, ndi kalendala yamphamvu yopanga.
