Alloy bushings ikemura ibibazo-byukuri byo kwambara no kudahuza-iyo byakozwe neza. Twabonye inteko ya hydraulic pompi yananiwe nyuma yamasaha 4.200 yo gukora kuko ibihuru bisanzwe byumuringa byahinduwe munsi yumutwaro wa radiyo. Twasimbuye ibyuma byacishijwe bugufi biyobora amaboko muri offshore winch center shafts hamwe na gakondo bushing bushing shyiramo - kandi wongerewe igihe cya serivisi kuri 3.7 ×. Ibi ntabwo ari theoretical. Nibikorwa-byerekanwe na metallurgie ikoreshwa kuri geometrie ikora.
Impamvu Bushings Yananiwe Kurenza Imizigo Yinganda
Kunanirwa kwinshi kugaruka kubintu bitatu bidahuye: uwo mutwaro urahagaze, ubushyuhe bugumaho, kandi guhuza ubuso bikomeza kuba bimwe. Mubyukuri, inzu ya pisitori ya piston ibona umuvuduko ukabije uri hejuru ya bar 450 mugihe ubushyuhe bwamavuta buva kuri 35 ° C kugeza 110 ° C mugihe cyakazi. Icyo cyuho cyo kwagura ubushyuhe? Niho hatangirira kudahuza. Ibiti by'umuringa byoroha hafi ya 150 ° C. Ibyuma-byuma-byuma byuma bidafite coefficient zo kugenzura. Kandi ibyuma bikozwemo kubura microstructural stabilite ikenewe kuri sub-0.015 mm kwihanganira kwiruka mumateraniro yihuta.
Twakurikiranye gutsindwa kwumurima 68 mumashanyarazi ya hydraulic yimodoka mumezi 18. 73% bagize uruhare mu gutanga amanota hakiri kare ku binyamakuru bya shaft - ntibiterwa no kwanduza, ahubwo byatewe no gutembera mu gihuru munsi ya MPa 120 yo guhura. Intandaro yabyo ntabwo yari umwanda. Byari umusaruro.
Alloy Bushing Ibikoresho: Guhuza Chimie Kumikorere
Ntabwo alloy all bushhing ikora kimwe. Amavuta ya Cobalt-nikel nka AMS 5387 atanga ubukana hejuru ya 45 HRC hamwe no kwagura ubushyuhe bwa zeru munsi ya 500 ° C. T800 amanota ashingiye kuri cobalt agumana imbaraga zo kwikuramo hejuru ya MPa 1100 kuri 600 ° C - ni ingenzi cyane kumanura ya pompe yamanutse ahura na gaze ikarishye n'umucanga utera. Ibyuma hamwe na chromium 3,2% na 1.8% ya molybdenum birwanya guhumeka neza kuruta icyuma gisanzwe cyoroshye - ariko iyo ubushyuhe bwakorewe kuri 28-32 HRC hanyuma bikarangirira kuri Ra ≤ 0.4 mm.
Dore icyakora-n'impamvu:
- Cobalt-nikel (AMS 5387): Ibyiza byo guhungabana imitwaro> 100 kN n'ubushyuhe> 400 ° C. Igumana ituze rinini muri ± 0.002 mm hejuru ya 10,000.
- T800 cobalt: Ibyiza kubitari amavuta cyangwa marike yimbere. Coefficient de friction iguma munsi ya 0.28 na nyuma yamasaha 500 yumye.
- Chromium-molybdenum itera ibyuma.
Ukoresheje cobalt alloy mumazu yoroheje ya garemotor? Kurenza urugero - kandi bihenze. Gukoresha ibyuma bikozwe mumashanyarazi ya offshore? Kwishingira gutemba mu mezi 18. Guhitamo ibikoresho ntabwo bijyanye na spes. Byerekeranye n'imipaka.
Igishushanyo & Gukora: Aho Precision ihinduka Imikorere
Ubuhanga bwa chimie yuzuye ntacyo bivuze nta geometrie isobanutse. Dukora imashini ya cobalt alloy bushings kuri 5-axis ya CNC hamwe na diyama ihinduranya imbere-kugera kuri mm0.003 mm hamwe no kurangiza Ra 0.2 mm. Kuki ibyo bifite akamaro? Kuberako mm 0.008 mm itameze neza yongerera imbaraga aho uhurira na 47% murwego rwo hejuru. Aho niho microcracks nucleate.
Inzira yacu ihuza gukina no gutunganya nkana. Kububiko bwa pisitori ya piston pompe, tujugunya igikonoshwa cyo hanze mubyuma byangiza (ASTM A), hanyuma ukande-bihuza imashini ya cobalt alloy liner. Kwivanga gukwiranye guhuza umurongo mu buryo bwuzuye - gukora pre-in preload irwanya imihangayiko ikora. Nta kibaho. Nta kugabanuka gukwiye. Gusa metallurgical synergy.
Buri cyiciro gikurikiranwa byuzuye: ibikoresho fatizo, ibiti bivura ubushyuhe, raporo ya CMM kuri ASME Y14.5, hamwe nigeragezwa rya nyuma ryibikorwa byumuvuduko n'umuvuduko. Niba igihuru kizunguruka kuri 1.800 rpm imbere muri shitingi ya winch, turazunguruka-tupima 2200 rpm muminota 30 mbere yo kohereza.
Igihe cyo Kugaragaza Alloy Bushing-Kandi Iyo Atari
Hitamo ibishishwa bivanze mugihe kimwe muribi gikurikizwa:
- Gutandukana kwa shaft kurenga 0,025 mm munsi yumutwaro ntarengwa
- Ubushyuhe bwo gukora burahinduka hejuru ya 60 ° C mugihe cyinshingano zisanzwe
- Umuvuduko wubuso urenga 1.5 m / s hamwe no gusiga rimwe na rimwe
- Igice gisaba ASME B16.34 cyangwa API 6A icyemezo
Ntugasobanure neza kuri static, umutwaro uremereye nka pivot yibikoresho cyangwa intoki za valve. Komera hamwe n'umuringa wa fosifore. Bika imikorere ya alloy aho ifite akamaro: umuvuduko wumuvuduko wikinga inshuro 12 kumunota, urufatiro rwa pompe rushyigikira toni 8 zizunguruka, cyangwa shitingi ya winch yo hanze yihanganira umunyu-spray wangirika no gupakira ibintu.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka ibyo bice-ntabwo nkibintu bya kataloge, ariko nkibikorwa bya sisitemu. Twemeje guhamagarwa kwa GD&T mbere yo guca ibyuma. Dushiraho ibishushanyo mbonera bifata umwuka mugihe cyo gukina. Turagerageza buri bushing bushing kurwanya ibikoresho byawe bifatika - ntabwo ari ibyuma rusange.
Kwambara no kudahuza ntabwo byanze bikunze. Nibimenyetso byibikoresho bidahuye, kwihanganira kwirengagizwa, cyangwa intera itemewe. Ubikemure kubisoko - ntabwo hamwe na gahunda yo kubungabunga, ariko hamwe nibisubizo byakozwe neza. Nuburyo wimuka ukava mubisimbuza reaction ukajya mubikorwa byateganijwe.
