Akatswiri akamatchula ziwiya zachitsulo kapena chitsulo chotuwa cha hydraulic system, zida zopangira mafuta, kapena mapampu olemetsa, samangofunika kuponya - amafunikira. kukhazikika kwamphamvu pansi pa 300+ bar pressure, kusasinthika kwa microstructure pamagulu a zidutswa 500,ndi kulekerera kwa zero pakuchepetsa porosity mu flanges zonyamula katundu. Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni kuponya chitsulo fakitale-osati wogulitsa malonda kapena maziko onse - sizingakambirane. Tawona mapulojekiti ambiri akuchedwa chifukwa cha ma graphite nodule owerengeka, kulimba kwa Brinell kosagwirizana (HBW 180-220 vs. chofunika 210-240), kapena zowonongeka zomwe zimakakamiza kukonzanso pambuyo pa makina. Mnzake woyenera amasamalira zitsulo ngati chilango - osati kungoganizira.
Chifukwa Chake Umphumphu Wakuthupi Umayambira Kale Kusanathiridwe
Zolephera zambiri zimayambira pakuwongolera zinthu - osati kuponya. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Gulu lililonse la EN-GJS-400-15 ductile iron limayamba ndi chitsulo chovomerezeka cha nkhumba ndi ferrosilicon kuchokera ku ISO 9001-certified smelters. Amatsimikizira kufanana kwa kaboni (CE) pofika pogwiritsa ntchito kusanthula kwa LECO - osati ma cert okha. Tayezera kutsetsereka kwa CE mpaka ± 0.15% m'malo osatsimikizika, zomwe zidapangitsa kutayika kwa nodularity m'nyumba zazitali. Labu yawo imayendetsa chitsimikiziro cha ASTM A536 pa kutentha kulikonse: kulimba kwamphamvu, kutalika, ndi kuuma - zonse zimayikidwa ndi ID ya ng'anjo, nthawi yothira, komanso kuzizira. Palibe "chitsanzo choyimilira" mipata. Izi sizikuchulukirachulukira - ndi momwe amagwirizira nyumba zamasilinda zamapampu a pistoni mpaka ± 0.02 mm kuzungulira pambuyo pakutenthetsa.
Kumene Kuponya Mchenga Kumakumana ndi Chilango cha CNC
Ziwalo zachitsulo zotuwa monga maziko a pampu kapena matupi a valve amafuna kukhazikika kolimba (<0.05 mm kupitirira 600 mm) ndi ma bore olondola opangidwa ndi makina. Komabe kuponya mchenga kokha sikungathe kupereka. QINGDAO QIANGSENYUAN imatsekereza kusiyana ndi njira zophatikizika zophatikizika: maziko awo amagwiritsa ntchito nkhungu zamchenga zomangika ndi utomoni zowunikira nthawi yeniyeni ya chinyezi, kenako amasamutsira ma cell a CNC m'nyumba 5-axis. Palibe ma handoffs akunja. Palibe kusiyana kwakukulu pakati pa kuponyera ndi kumaliza Machining. Amagwiritsa ntchito makina osindikizira ovuta pamene kuponyera kumachepetsera kupsinjika-kudula kupotoza kwa kutentha ndi 40% motsutsana ndi makina a post-annealing. Pa mavavu okakamiza omwe amafunikira AMS 2700 Class 2 passivation, amaphatikiza peening ndi nitric acid kuyeretsa musanayang'ane komaliza. Si "kuponya + makina." Ndi mndandanda womwe umapangidwa.
Kutsimikizika Kwapadziko Lonse: Zomwe Makasitomala Amayesa
Makasitomala akumalo opangira mafuta aku North America samavomereza malipoti oyesa-amatsimikizira bwino. Makasitomala m'modzi adayesa ma roller 12 a winch center shaft pansi pa 120,000-cycle kutopa atanyamula pa -20°C. Zonse zadutsa. Wina anathamangitsa cobalt-aloyi nozzles (AMS 5387) motsutsana abrasive slurry kwa maola 72—ziro kukokoloka kupitirira 0.03 mm kuya kwake. Izi sizinthu za labotale. Ndi zigawo zopanga zomwe zimatumizidwa ndi kutsata kwathunthu: nambala ya kutentha, kusindikiza kusanthula kwamankhwala, lipoti la CMM la ma callout onse a GD&T, ndi ma micrograph owonetsa ma graphite morphology pa ISO 945-1. Pamene OEM pump yaku Europe idafuna ISO 13003-yogwirizana ndi kulimba kwachitsulo cha EN-GJL-250 imvi yachitsulo, idapereka ma Charpy V-notch impact values-osati kungokhazikika. Umu ndi momwe mumapewa zodabwitsa "zinkawoneka bwino pachithunzichi".
Kusankha Fakitale Yanu Yoponya Iron: Macheke Atatu Osakambirana
- Funsani zolemba zawo zomaliza zamagulu atatu-osati satifiketi. Tsimikizirani ngati kuuma, kulimba kwamphamvu, ndi kapangidwe kake kamalembedwa pa kutentha, osati pagawo lililonse.
- Pamafunika umboni wogwiritsa ntchito CMM-osati kuyendera komaliza kokha. Miyeso yovuta iyenera kufufuzidwa pambuyo pokonza movutikira komanso musanamalize.
- Tsimikizirani kuti ali ndi zida zonse zoponya ndi makina. Njira zakunja zimawonjezera nthawi yotsogolera masiku 7-12 ndikuyambitsa zolakwika zamalumikizidwe zomwe palibe chidziwitso cha GD&T chomwe chingakonze.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amakumana onse atatu. Malo awo ku Qingdao amagwira ntchito pansi pa ISO 9001:2015 ndipo amasunga ndondomeko zolembedwa pa sitepe iliyonse-kuyambira kukonzekera mchenga mpaka kuyika komaliza. Amatumiza ku North America, Europe, ndi Southeast Asia ali ndi zolemba zonse zamakasitomu komanso kutsata kwa RoHS/REACH komwe kumapangidwa muzinthu zakuthupi. Ngati nyumba yanu yotsatira yachitsulo iyenera kukhala ndi moyo kwa zaka 20 mu makina opangira valavu ya subsea - kapena maziko anu a pampu yachitsulo imvi ayenera kuchepetsa kugwedezeka pa 3,600 RPM - kuyamba ndi zitsulo zolimba, osati zotsatsa malonda. Amphamvu kwambiri kuponya chitsulo fakitale sichimalonjeza ungwiro. Kumatsimikizira kusinthasintha—kutentha kumodzi, kuponyedwa kumodzi, muyeso umodzi panthaŵi imodzi.
