Zoponyera zitsulo zotayira zimapereka mphamvu zosayerekezeka, kulimba, ndi kukhazikika kwamafuta komwe kulephera sikungachitike - ma hydraulic manifolds pansi pa 350 bar, nyumba zapampopi zakunyanja zowululidwa ndi madzi a m'nyanja ndi ma abrasion a mchenga, kapena zodzigudubuza za winch center shaft pazofukula migodi zonyamula katundu wa matani angapo. Izi sizimangokhala zitsulo. Ndiwo zisankho zolemetsa zomwe zimapangidwa mumchenga woyambira ndikutsimikiziridwa mu labotale ya metrology.
Tawona ntchito zambiri zikuyimitsidwa pamene mainjiniya amatchula "kuponya zitsulo" popanda kulongosola kalasi, kutentha kwa kutentha, kapena zofunikira za zone. Thupi la valavu la ASTM A216 WCB likhoza kudutsa hydrotest-koma limasweka panthawi yoyendetsa njinga yamoto ngati yokhazikika m'malo mozimitsidwa ndi kupsya mtima. Nyumba ya silinda ya pampu ya pisitoni yopangidwa kuchokera ku bala yopukutira imapulumutsa nthawi koma imalepheretsa kutopa kwa isotropic poyerekeza ndi chitsulo choyatsidwa ndi chitsulo chotchinga bwino komanso chotenthetsera. Chifukwa chake zida zachitsulo amakhalabe osasinthika m'mafakitale ofunikira kwambiri: amaphatikiza kupitiliza kwadongosolo ndi ufulu wamapangidwe palibe chinyengo kapena chinyengo chomwe chingafanane.
Zinthu zitatu zaukadaulo zimasiyanitsa chitsulo chochita bwino kwambiri ndi zinthu zomwe zimatuluka:
- Kuwongolera kwazitsulo kumayamba musanathire. Kufufuza kwazinthu zopangira sizinthu zamapepala-ndi malipoti oyesa mphero a carbon, chromium, molybdenum, ndi zinthu zotsalira monga mkuwa ndi malata. Nthawi ina tinakana kutentha kwathunthu kwa ASTM A352 LCB chifukwa tsankho la sulfure lidaposa 0.025% m'dera lokwera - losawoneka ndi kuyang'ana kowoneka koma kutsimikiziridwa kupha pakutsitsa kutentha kwapang'onopang'ono.
- Dimensional umphumphu zimatengera kuphatikizika ndondomeko-osati kuponyera. Maziko a mpope a 420 mm OD amayenera kukhala ndi ± 0.15 mm kuzungulira pamipando yonyamula * pambuyo * kuchepetsa kupsinjika, kukonza makina, ndikuwunika komaliza. Izi zimafuna kufananizidwa kocheperako, ma gating okhazikika, komanso kugwira ntchito kwa CNC komwe kumawonetsa ma data-osati omalizidwa.
- Ubwino wapamtunda umatanthawuza ntchito-osati kumaliza. Nozzle ya AMS 5387 cobalt alloy sipukutidwa kuti iwoneke. Zake za 0.8 µm Ra mkati mwake zimachepetsa kukokoloka kwa cavitation. Ziphuphu zake zakunja zimapewa kupsinjika kwa cyclic pressure spikes. Pamwamba sikokongola. Ndi magwiridwe antchito.
Ena amatsutsa kuponya ndalama kumapereka mapeto abwino kuposa kuponya mchenga-choncho bwanji mugwiritse ntchito mchenga? Chifukwa mchenga umagwira misa, geometry, ndi aloyi zovuta zomwe zimasungunula zisankho. Wodzigudubuza wolemera wa 220 kg wopangira ma winch center shaft wokhala ndi mayendedwe ozizira amkati ndi ma asymmetric flanges? Kuponyera kwa mchenga kumawongolera mawotchi otentha kudutsa zigawo zokhuthala; njira zoyendetsera ndalama zitha kusokoneza kapena kutha. Kugulitsa kwenikweni sikutha kuyerekeza ndi kulondola - ndi mtengo wathunthu wa umwini motsutsana ndi njira imodzi yokha. Nthawi zonse timaphatikiza zonse ziwiri: matupi opangidwa ndi mchenga okhala ndi zoyikapo ndalama zogulira malo ovala-kenako amawapanga ngati gawo limodzi.
Chilango cha haibridi ichi chimafuna luso loyima. Simungathe kutulutsa chithandizo cha kutentha ndikuyembekezera mphamvu zobwerezabwereza zobwerezabwereza pamagawo a khoma la 120 mm. Simungadalire NDT ya chipani chachitatu pamene kuyang'anira kwa akupanga kuyenera kupanga mapu mkati mwa 3 mm wa malo osindikizira opangidwa ndi makina. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Aliyense kuponya zitsulo imadutsa pazipata zinayi zosakambitsirana: kutsimikizira kwazinthu zopangira zovomerezeka (ndi CoA yotchulidwa pamtanda kutentha nambala), mu ndondomeko CMM kupanga sikani pa siteji wobiriwira ndi pambuyo kutentha mankhwala, 100% MPI/UT pa madera ovuta pa ASTM E165 / E1444, ndi komaliza ntchito kutsimikizira-monga kukanikiza ntchito kudziwika kwa hydraulium heak × 5. 1×10⁻⁶ mbar·L/s kukhudzika.
Zotsatira zake? Zigawo zomwe zimapulumuka pomwe ena amatopa. Ma valve opanikizika akugwira ntchito mosalekeza pa 200 ° C mu mizere ya nthunzi ya geothermal. Nyumba zokhala ndi ma cylinder zomwe zimapirira kuzungulira kwamphamvu kwa 15 miliyoni mu subsea hydraulic actuators. Maziko a pampu omwe amayamwa kugwedezeka kwa torsional ndikusunga kuyanjanitsa mkati mwa 0.03 mm kupitilira ma mita atatu. Izi siziri zongopeka chabe. Ndizotsatira zotsimikizirika m'munda - zolembedwa m'malipoti aku North Sea, malo amchenga amafuta aku Alberta, ndi zombo zaku Southeast Asia.
Kuyang'ana m'tsogolo, malirewo samangokhala aloyi amphamvu - ndi kuphatikiza kwanzeru. Tikukulitsa R&D m'njira zosakanizidwa zopangira makina: kuyika ma geji akusefukira mu nkhungu zamchenga kuyang'anira kupsinjika kwamphamvu munthawi yeniyeni; kugwiritsa ntchito chithunzithunzi chotenthetsera choyendetsedwa ndi AI kulosera kuchepa kwapang'onopang'ono makina asanayambe; oyenerera zida zatsopano za T800 za cobalt-zitsulo zopangira ma ultra-high-cycle pump impellers. Koma palibe chomwe chikufunika ngati chowonadi chowoneka bwino chitayika pakati pa kujambula ndi kutumiza. Ichi ndichifukwa chake kudzipereka kwathu kolimba sikunasinthe: chilichonse kuponya zitsulo zombo zokhala ndi traceability zonse, malipoti oyendera ogwirizana ndi GD&T, komanso gawo limodzi laukadaulo - kuyambira pakuwunika koyambira mpaka kusanthula kulephera kwamunda.
