Kukandwa kwesimbi kunopa simba risingaenzaniswi, kusimba, uye kugadzikana kwekupisa uko kutadza kusiri sarudzo - hydraulic manifolds pasi pe350 bar, offshore pombi dzimba dzakaratidzwa nemvura yegungwa uye jecha abrasion, kana winch centre shaft rollers pamigodhi yekuchera migodhi inotakura matani akawanda. Izvi hazvisi zvikamu zvesimbi chete. Idzo sarudzo dzinotakura dzakaitwa mujecha rekutanga uye dzakasimbiswa mumalabhu emetrology.
Takaona mapurojekiti akawandisa achimira apo mainjiniya anotsanangura "kukandira simbi" pasina kujekesa giredhi, mamiriro ekurapa kupisa, kana zvakakosha zvenzvimbo. A ASTM A216 WCB valve body inogona kupfuura hydrotest-asi inotsemuka panguva yekupisa bhasikoro kana yakajairwa pane kudzimwa uye kushatirwa. Imba yepiston pombi cylinder yakagadzirwa kubva kubhawa yakagadzirwa inochengetedza nguva asi inobayira isotropic kuneta kuramba kana ichienzaniswa neyakavharwa uye yemashure-weld kupisa-yakagadziriswa simbi yekukandira. Ndosaka cast steel castings vanoramba vasingadzoreki mumishini-yakakosha maindasitiri masisitimu: vanosanganisa kuenderera kwechimiro nerusununguko rwekugadzira hapana kuumba kana kugadzirwa kunogona kuenderana.
Zvinhu zvitatu zvetekinoroji zvinopatsanura yakakwira-inoshanda simbi kubva kune zvigadzirwa zvinobuda:
- Metallurgical control inotanga isati yadururwa. Raw material traceability haisi mapepa - ndeye batch-specific mill test report ye carbon, chromium, molybdenum, uye zvakasara zvinhu zvakaita semhangura netin. Isu takamboramba kupisa kwakazara kweASTM A352 LCB nekuti kuparadzaniswa kwesarufa kwakapfuura 0.025% munzvimbo inosimuka-isingaonekwe nekutarisa kwekuona asi yakaratidza kuuraya mukudzika-tembiricha kuvhunduka kurodha.
- Dimensional kutendeseka kunoenderana nekubatanidzwa kwemaitiro-kwete kungokanda. Iyo 420 mm OD pombi hwaro inofanirwa kubata ± 0.15 mm kutenderera pakutakura zvigaro * mushure me* kudzoreredza-kudzoreredza, kugadzira, uye kuongorora kwekupedzisira. Izvo zvinoda kurongedzerwa shrink mvumo yekuenzanisira, gwara rekusimbisa gating, uye CNC kubata iyo inonongedza se-akakanda datums-kwete chete apera.
- Unhu hwepamusoro hunotsanangura basa-kwete kupera. Iyo AMS 5387 cobalt alloy nozzle haina kupukutwa kuti itaridzike. Yayo 0.8 µm Ra yemukati bore inoderedza mhirizhonga-induced cavitation erosion. Mafiritsi ayo ekunze anodzivirira kushushikana mupfungwa pasi pe cyclic pressure spikes. Surface haina kunaka. Iri calibrated performance.
Vamwe vanopokana kukanda kwekudyara kunopa kupedzisa kuri nani pane kukanda jecha-saka sei uchishandisa jecha zvachose? Nekuti jecha rinobata misa, geometry, uye alloy kuomarara kunonyungudutsa maforoma ekudyara. Iyo 220 kg engineering mota winch centre shaft roller ine yemukati yekutonhodza chiteshi uye asymmetric flanges? Kukandira jecha kunodzora kupisa kwemagetsi mukati mezvikamu zvakakora; nzira dzekudyara dzaizokanganisa kana kupisa. Kutengeserana chaiko hakusi kupera kupesana nemazvo-ndiwo mutengo wakazara wevaridzi uchipesana ne-single-process nyore. Isu tinogara tichibatanidza ese ari maviri: jecha-akakanda maumbirwo emitumbi nekudyara-kukandwa kwekuisa munzvimbo dzakapfeka- tobva tazvigadzira sechikamu chimwe chinoshanda.
Ichi chirango chehybrid chinoda kugona kwakamira. Iwe haugone kupa kunze kwekupisa kurapwa uye kutarisira kudzokororwa kusimba kwesimba mukati me120 mm emadziro zvikamu. Iwe haugone kuvimba neyechitatu-bato NDT apo ultrasonic ongororo inofanirwa mepu porosity mukati me3 mm yemuchina yekuvharisa chisimbiso. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., zvese cast steel casting inopfuura nepamasuwo mana asingagone kutaurirana: yakasimbiswa mbishi yekuongorora (ine CoA-yakatarwa kunhamba yekupisa), in-process CMM scanning pane yakasvibira uye post-kupisa-kupisa matanho, 100% MPI/UT panzvimbo dzakakomba pane ASTM E165 / E1444, uye yekupedzisira inoshanda kusimbiswa-kufanana nekumanikidza kuyedza hydraulium yekuona × 5 × 1×10⁻⁶ mbar·L/s kunzwa.
Zvakaguma nei? Zvikamu zvinopona panoneta vamwe. Mavharuvhu ekudzvanya achishanda achiramba ari 200 ° C mugeothermal steam mitsetse. Cylinder dzimba dzinotsungirira mamirioni gumi neshanu ekumanikidzwa kutenderera mu subsea hydraulic actuators. Pombi nheyo dzinotora torsional vibration ichiri kuchengetedza kurongeka mukati me 0.03 mm pamusoro pe 3-mita spans. Aya haasi iwo theoretical specs. Iwo mhedzisiro yemunda-yakanyorwa mumasevhisi mishumo kubva kuNorth Sea mapuratifomu, Alberta mafuta ejecha nzvimbo, uye Southeast Asia dredging zvikepe.
Kutarisa kumberi, muganho haungori ma alloys akasimba-iyo yakangwara kusanganisa. Isu tiri kuwedzera R&D mukukanda-machining hybrid maitiro: kunyudza dhizaini geji zvakananga mujecha molds kutarisa kusimba kwekushushikana munguva chaiyo; kushandisa AI-inotyairwa thermal imaging kufanotaura micro-shrinkage isati yatanga machining; inokodzera itsva T800-yakavakirwa cobalt-simbi macomposites kune ekupedzisira-yakakwirira-kutenderera pombi impellers. Asi hapana chimwe cheizvi chine basa kana chokwadi chedimensional chikarasika pakati pekudhirowa nekutakura. Ndicho chikonzero kuzvipira kwedu kwakasimba kunoramba kusingachinjiki: zvese cast steel casting Zvikepe zvine zvizere zvekuteedzera zvinhu, GD&T-inopindirana yekuongorora mishumo, uye imwe poindi yekuzvidavirira kwehunyanzvi-kubva kuongororo yekutanga sketch kusvika pakuongorora kutadza kwemunda.
