Alloy bushings inogadzirisa-chaiyo-yenyika yekupfeka uye kusarongeka matambudziko-kana iwo akagadzirwa zvakanaka. Isu takaona hydraulic pombi maassemblies achikundikana mushure memaawa mana nemazana maviri ekushanda nekuda kwekuti mabhuronzi akajairwa akaremara pasi pe cyclic radial load. Isu takatsiva akatsemuka-simbi dhiraivha maoko mune offshore winch centre shafts netsika alloy bushing kuisa-uye hupenyu hwesevhisi hwakawedzerwa ne3.7×. Izvi hazvisi dzidziso. Iyo simbi-yakaratidza simbi inoshandiswa kune inoshanda geometry.
Nei Standard Bushings Inotadza Pasi peMitoro Yemaindasitiri
Kukundikana kwakawanda kunodzokera kumashure ekufungidzira kusingaenderani kutatu: kuti mutoro wakamira, tembiricha inoramba iripo, uye kubata kwepamusoro kunoramba kwakafanana. Muchokwadi, piston pombi silinda dzimba dzinoona kudzvanywa kwepamusoro pe450 bar ukuwo tembiricha yemafuta ichichinjika kubva pa35 ° C kusvika 110 ° C panguva yebasa. Iyo gap yekuwedzera kwekupisa? Ndipo panotangira kusarongeka. Bronze bushings inopfava kusvika 150°C. Simbi-pa-simbi inopindirana nenduru isina inodzorwa kukweshana coefficients. Uye simbi yakakandwa inoshaya iyo microstructural kugadzikana inodiwa kune sub-0.015 mm runout kushivirira mumagungano ekumhanya-mhanya anotenderera.
Isu takatsvaga 68 kutadza kwemunda mukati meinjiniya mota hydraulic masisitimu pamusoro pemwedzi gumi nemasere. 73% yaisanganisira kupihwa nguva isati yakwana pamajenari eshaft-yakakonzerwa kwete nekusvibiswa, asi nekukwira kwegwenzi pasi pe120 MPa yekusangana kushushikana. Chikonzero chikuru chakanga chisiri tsvina. Chakanga chiri zvibereko zvokunyama.
Alloy Bushing Zvishandiso: Kufananidza Chemistry kune Basa
Haasi ese alloy bushings anoita zvakaenzana. Cobalt-nickel alloys seAMS 5387 inoburitsa kuomarara pamusoro pe45 HRC ine padyo-zero yekuwedzera yekupisa iri pasi pe500°C. T800 cobalt-based kiredhiti inochengetedza simba rekumanikidza riri pamusoro pe1,100 MPa pa600 ° C-yakakosha kune downhole pombi nozzles akafumurwa gasi rakavava nejecha rinoputika. Iron castings ine 3.2% chromium uye 1.8% molybdenum inodzivisa galling zviri nani pane plain grey iron-asi chete kana inopisa-yakagadziriswa kusvika 28-32 HRC uye kupera-pasi kusvika kuRa ≤0.4 μm.
Hezvino izvo zvinoshanda-uye nei:
- Cobalt-nickel (AMS 5387): Yakanakira kutakurisa mitoro >100 kN uye tembiricha >400°C. Inochengetedza kugadzikana kwedimensional mukati me ± 0.002 mm pamusoro pe10,000 mitenderera.
- T800 cobalt alloy: Yakanyanya kunaka kune isina-kuzora mafuta kana kuomeswa zvishoma. Coefficient of friction inogara pazasi 0.28 kunyangwe mushure me500 hrs yakaoma kumhanya.
- Chromium-molybdenum simbi yakakandwa: Inodhura-inoshanda pamavharuvhu epakati-kudzvanya uko kumhanya kwepamusoro kunogara pasi pe1.2 m/s uye tembiricha inogara iri pasi pe120°C.
Uchishandisa cobalt alloy mune yakaderera-mutoro gearmotor imba? Overkill-uye inodhura. Kushandisa simbi yakakandwa mune yekumahombekombe pombi hwaro? Guaranteed spalling mukati memwedzi gumi nemasere. Kusarudzwa kwezvinhu hakusi kwezvimiro. Zviri pamusoro pemiganhu yemiganhu.
Dhizaini & Kugadzira: Iko Kurongeka Kunova Kuita
Yakakwana alloy chemistry hairevi chinhu pasina chaiyo geometry. Isu tinochina cobalt alloy bushings pa5-axis CNC nzvimbo nedhaimondi-yakatendeuka mukati mabhori-kusvika kutenderera ≤0.003 mm uye kupera kwepamusoro Ra 0.2 μm. Nei izvozvo zvine basa? Nekuti 0.008 mm kunze-kwe-kutenderera mamiriro anowedzera localized contact stress ne 47% panzvimbo yakakwirira. Ndiko uko microcracks nucleate.
Maitiro edu anobatanidza kukanda uye kugadzira nemaune. Kune dzimba dzepiston pombi humburumbira, tinokandira ganda rekunze mu ductile iron (ASTM A), tobva tadzvanya-inokodzera cobalt alloy liner. Iko kupindira kwakakodzera kunomanikidza liner radially-inogadzira yakavakirwa-mukati preload iyo inoverengera mashandiro ekutemesa kushushikana. Hapana zvinonamira. Hapana shrink inokwana. Just metallurgical synergy.
Batch rega rega rinowana kuteedzera kuzere: mareti emidziyo, matanda ekupisa, CMM mishumo paASME Y14.5, uye yekupedzisira kushanda kuyedzwa pakumanikidzwa kwakayerwa uye kumhanya. Kana bushing ichitenderera pa1,800 rpm mukati mewinch centre shaft, tinoipinza-inoedza pa2,200 rpm kwemaminitsi makumi matatu tisati tatumira.
Nguva Yekudoma Alloy Bushing-Uye Kana Isingaite
Sarudza alloy bushings kana chero ipi zvayo inoshanda:
- Shaft deflection inodarika 0.025 mm pasi pemutoro mukuru
- Kushanda tembiricha inochinja kupfuura 60°C panguva yakajairika basa kutenderera
- Kumhanya kwepamusoro kunodarika 1.5 m/s nekuzora kwepakati
- Chikamu chinoda ASME B16.34 kana API 6A chitupa
Usazvitsanangure kune static, yakaderera-mutoro maapplication senge chiridzwa chepaneru pivots kana manyorero mavharuvhu anobata. Batira nefosphor bronze ipapo. Chengetedza mashandiro ealloy pazvine basa: mavharuvhu ekumanikidza kuchovha bhasikoro kagumi nembiri paminiti, pombi nheyo dzinotsigira 8-ton inotenderera masasi, kana offshore winch shafts inotsungirira munyu-spray corrosion uye kuvhunduka kurodha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inovaka izvi zvikamu-kwete sezvinhu zvekabhuku, asi sesystem-yakakosha interfaces. Isu tinosimbisa GD&T callouts tisati tacheka simbi. Isu tinoisa mireza makona anoteya mweya panguva yekukanda. Isu tinoedza zvese alloy bushing kupesana neyako chaiyo shaft zvinhu-kwete generic simbi.
Kupfeka uye kusarongeka hazvidzivisiki. Iwo zviratidzo zvezvinhu zvisingaenderane, kushivirira kusingatarisirwe, kana kusawirirana kusingabvumirwe. Vagadzirise panobva — kwete nemarongwa ekugadzirisa, asi nemazvo-engineered mhinduro. Ndiwo mafambiro aunofamba kubva kune reactive kutsiva kuenda kunofungidzirwa kuita.
