Xa iinjineli zichaza a umzi-mveliso weshaft wokuqondisa, abagcini nje ukukhangela icandelo elijikelezayo-bakhetha iqabane elikwaziyo ukubamba ukunyamezela kwe-± 0.005 mm phantsi kwe-300 MPa imithwalo ye-hydraulic, ukuxhathisa i-galling kwiindawo ezinqabileyo ezinodaka, kunye nokuhambisa ukulandelwa kwezinto ezigcweleyo ukuya kwinani lobushushu. Elo nqanaba lokuphendula alifane livele kwiivenkile zentsimbi ezinenjongo ngokubanzi.
Siye sabona iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype kuba ishaft-eyenzelwe ukulungelelaniswa kwesantya esiphezulu kwi-centrifugal pump test rigs-igqwethiweyo ngexesha lonyango lobushushu. Okanye uvavanyo lwe-vibration aluphumelelanga emva kweeyure ze-42 ngenxa ye-micro-porosity engabonakaliyo kwi-casting core. Ezi ayingomngcipheko wethiyori. Ziindlela eziphinda-phindayo zokusilela esizifumeneyo kumazwekazi amathathu, kwiinkqubo ze-winch ye-oilfield, ii-marine hydraulic actuators, kunye neempompo zokudosa iikhemikhali ezinoxinzelelo oluphezulu.
Ukuchaneka kuqala apho i-metallurgy idibana nejometri
I-shaft yokuqondisa ayiyona i-cylinder elula. I-interface esebenzayo: isiphelo esinye sihambelana nogqatso oluchanekileyo lomhlaba; i-middle-section ithwala amazinyo e-spline aqinile ahambisa i-torque ngelixa i-self-centering i-couplings engafanelekanga; imisonto yesiphelo esichaseneyo ibe yindibano yerotor eguqukayo. Nakuphi na ukutenxa kubunzulu, ukugqiba komphezulu (Ra ≤ 0.4 µm), okanye usasazo loxinzelelo olushiyekileyo lusasazeka njengengxolo, ukuguga, okanye ukudinwa okuyintlekele.
Yiyo loo nto ukhetho lwempahla lungenakukhutshelwa ngaphandle kwedatha. I-cobalt-nickel alloys efana ne-AMS 5387 ihambisa ukuxhathisa kwe-corrosion kunye nobunzima obushushu-kodwa basebenza ngomatshini kwi-1/3 izinga lokutya kwe-4140 yentsimbi kunye nokufuna ukuseta okuqinileyo, izixhobo ze-cryogenic, kunye nokubeka iliso ngexesha langempela le-thermal. I-T800-based shafts ifuna ukuchithwa kotyalo-mali kunye ne-ceramic shell molds, ilandelwa yi-HIP (i-hot isostatic pressing) ukuvala i-voids yangaphakathi-emva koko i-CNC ivula oomatshini abane-sub-micron axis positioning. Ukutsiba naliphi na inyathelo kuthoba ingqibelelo.
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha i-shaft nganye njenge-node ebaluleke kakhulu kwinkqubo-kungekhona inxalenye yempahla. Indawo yethu ethobela i-ISO eQingdao idibanisa ukuphosa, umatshini we-multi-axis, kunye nokugqitywa komphezulu phantsi kophahla olunye. Akukho handoffs. Akukho kudluliselwa kwebhetshi. Xa umthengi ethumela imizobo ye-GD&T yobude obuyi-320 mm ubude, i-65 mm ye-diameter shaft ene-12 ° helical splines kunye ne-HRC 58-62 ubunzulu betyala, iqela lethu liqinisekisa ukwenziwa kwe-manufacturability * phambi * kokucaphula-iflegi yeendawo zokuncokola ezinokubakho, icebisa ukulandelelana kwendlela yesixhobo, kunye nokuqinisekisa ukunyanzeliswa kwesigaba sobushushu kunye nomjikelo wedayagram.
Ukudityaniswa ngokuthe nkqo akukho lula-lulawulo
Abanye ababoneleli bakhuphela ngaphandle, emva koko basebenza ngomatshini, emva koko bathumele iinxalenye kwiivenkile zomntu wesithathu. Isandla ngasinye sazisa ukuguquguquka: ukungangqinelani kolwakhiwo lwenkozo olusuka kwiinkqubo zesiseko ezingangqinisiswanga, ukukhukuliseka komda ukusuka ekulungisweni kwakhona, ukungcoliseka komphezulu ngaphambi kokusila okugqithisiweyo. Silinganise ukuya kuthi ga kwi-18 µm umahluko ophumayo phakathi kokusakhasayo okungenayo kunye neeshafti ezigqityiweyo xa iinkqubo zisahluliwe.
Ukuhamba kwethu okudityanisiweyo ngokuthe nkqo kuphelisa ezo zithuba:
- Ukugalela endlini: Isanti kunye nemigca yokuphosa yotyalo-mali ilinganiswe kwi-cobalt alloys-akukho kuxhomekeka kwiziseko zangaphandle ezineprofayili zesithando somlilo
- Umatshini kwizixhobo ezibhalisiweyo: Amaziko e-CNC e-5-axis anezixhobo eziphilayo, ii-Renishaw probes, kunye nenkqubo yokuqinisekisa i-CMM kwiidamitha ezibalulekileyo.
- Ukugqiba ngenjongo: I-electroless nickel plating yokumelana nokunxiba, ukudubula ukukroba ngenxa yoxinzelelo lomphezulu ocinezelayo, okanye ukumenyezeliswa kwesipili kwindawo yojongano lwetywina-kusetyenziswa kuphela apho umsebenzi ufuna khona.
Oku akukho malunga nokunciphisa iindleko. Imalunga nokuphelisa izinto eziguquguqukayo ezitshabalalisa ukuphindaphinda. Umtshini owenziwe kumatshini ongakhange ube ne-laser-calibrated kwiinyanga ezili-9 unokuhlangabezana nokunyamezela ukuprintwa namhlanje-kwaye ungaphumeleli uphicotho ngomso. Sihlaziya rhoqo iiyure ezingama-72 zemveliso. Yonke indawo ephathwa ubushushu ifumana isiqinisekiso seBrinell kunye neRockwell. Yonke i-shaft egqityiweyo ifumana i-100% yokuhlolwa kwamehlo kwiziphene zomhlaba kunye nokuqinisekiswa kwe-CMM ngokuchasene nemodeli ye-CAD yokuqala.
Kutheni i-specs "eqhelekileyo" ingasebenzi kwi-shafts-critical shafts
“Yenze nje uye kwi-ASTM A494 iBanga le-M35-1”—eso sicelo asisixeleli nto malunga nemvulophu yakho yokusebenza. Ingaba le shaft ijikeleza kwi-4,200 RPM ngaphakathi kwevalve ye-subsea actuator? Ngaba ijikeleza amaxesha angama-12,000 ngeveki kuloliwe womxube wesamente wegiya leplanethi? Ngaba iyakubona ukuvezwa okuphakathi kwe-H₂S okanye kumanzi olwandle akloriniweyo?
Sibuza loo mibuzo-kungekhona ngenxa yokuba sinandipha amaphepha, kodwa ngenxa yokuba impendulo iguqula yonke into: ukukhethwa kwebakala lezinto eziphathekayo, ixesha lokufudumala ukushisa, indlela yokuvavanya engonakalisi (UT vs. MPI), kunye neprotocol yokupakisha (i-vapor-phase inhibitors yokuthunyelwa kwamanye amazwe). Enye impompo ye-OEM yaseYurophu yafunda oku ngendlela enzima: ishafti yabo “eqhelekileyo” yentsimbi etyiwayo yadleka kwisithuba seeveki ezi-3 kwisitofu se-brine-injection. Ukutshintshela kwi-AMS 5387 ngokusasazwa kwe-carbide elawulwayo kwandisa ubomi benkonzo kwiinyanga ezili-18.
Olo tshintsho lwalungengomlingo. Ivela kuphononongo oludibeneyo lobunjineli-apho senze imephu yendlela yokungaphumeleli kwabo, idatha yokusebenza kwe-alloy-referenced evela kwi-NACE MR0175, kwaye yaqinisekisa iinkcukacha ezintsha ngovavanyo olukhawulezileyo lobomi kwilebhu yethu.
Jonga ngaphaya komzobo—jonga indlela yokunikela intetho
I-shaft egqibeleleyo ngokobuchwepheshe ayithethi nto ukuba ifike emva kweeveki ezimbini ukuze ithunyelwe. Okanye ukuba iiyunithi zokuqala ezili-10 ziphumelele ukuhlolwa-kodwa i-11 iyasilela ngenxa yenkqubo engabhalwanga. Sinyanzelisa iindlela zokuhamba komsebenzi: Ukulawulwa kwe-Kanban-ukulawulwa kwezinto eziluhlaza, ii-odolo zomsebenzi ezilandelelanisiweyo ezineendawo zokujonga ezifakwe kwi-QC, kunye needashbhodi zexesha lokwenyani ezifikelelekayo kubathengi.
Ukuqhuba iprototype, sithumela iingxelo zenqaku lokuqala kunye nedatha epheleleyo ye-metrology-kuquka iilog zembuyekezo yolwandiso lobushushu. Kwiiodolo ezinomthamo ophakathi, sibambe isitokhwe se-buffer yeebhilithi eziqinisekisiweyo ukufunxa ukothuka kwekhonkco lonikezelo ngaphandle kokubeka esichengeni umnombo wemathiriyeli.
Ukuba ufuna i umzi-mveliso weshaft wokuqondisa ephatha uzinzo lwe-dimensional njengento engenakuxoxisana, ukuhambelana kwesinyithi njengento enyanzelekileyo, kunye nokunikezelwa ngexesha njengobungqina benkqubo yoqeqesho-ukuqala ngothethwano lobugcisa, hayi ii-RFQs. Ndwendwela https://www.tsingtaocnc.com ukuphonononga iingxelo zesakhono, iziqinisekiso zemathiriyeli, kunye nezishwankathelo zetyala lehlabathi lokwenyani. Ishaft oyichazayo namhlanje iya kuchaza ukuthembeka kwenkqubo iminyaka. Khetha ngokufanelekileyo.
