Iindawo zokuphosa ezikumgangatho ophezulu azigcini nje phantsi koxinzelelo- ziyayenza. Kwiintlobo ezininzi ze-hydraulic, iindibano zempompo ezikude nonxweme, okanye ii-winch-duty-winch systems, i-0.05 mm yempazamo yokunyamezela ayiyo "tenxa encinci." Ibambe ipistons. Kukudinwa kwangaphambi kwexesha kwimilomo ye-cobalt-alloy evezwe kwi-450 ° C ukukhwela ibhayisekile ngokushushu. Yixesha lokuphumla elingacwangciswanga elixabisa i-18,000 yeedola / iyure kwi-oilfield service rig. Sizibonile zontathu-ngokuphindaphindiweyo-ngexesha lokuphonononga ubunjineli kunye ne-OEMs yaseMntla yaseMelika kunye nabanikezeli be-Tier-1 yaseYurophu. Oyena nobangela? Hayi ibakala lezinto eziphathekayo. Ayiyonjongo yoyilo. Ngumsantsa phakathi kokuphoswa njengenkqubo yorhwebo-kunye nokuphosa njengoqeqesho lobunjineli obusebenzayo.
Ukuphosa okuchanekileyo kuqala apho isanti idibana ne-Metallurgy
Uninzi lwabathengi baphatha iindawo zokuphosa njengezithuba ezingenanto: "Yiphose kufutshane, emva koko umatshini ushiye." Loo ndlela iyasilela xa ubukhulu bodonga buguquguquka ± 1.2 mm ngaphaya kwe-320 mm yendlu yesilinda-okanye xa uxinzelelo olushiyekileyo olusuka ekupholiseni okungalinganiyo luphazamisa isiseko sempompo yensimbi engenasici emva kokunyangwa kobushushu. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siyibuyisela umva loo ngqiqo. Yonke into yokuphosa intsimbi iqala ngokuqiniswa kokulinganisa. Lonke icandelo le-AMS 5387 cobalt alloy lenziwa kwimaphu yesakhiwo senkozo phambi koyilo lwesango. Ngoba? Ngenxa yokuba ukucutheka akuqhelekanga-kuyacingeleka. Kwaye ukuqikelela kuthetha ukulawula ingqibelelo ye-microstructure *phambi* kokugalelwa kokuqala.
Kungenxa yoko le nto izindlu zethu zempompo zepiston zesanti zifezekisa i-Cpk ≥1.67 kwi-bores ebaluleke kakhulu-nangona ngaphandle kokukhululeka koxinzelelo lwasemva. Yiyo loo nto i-T800-based non-standard plugs igcina ukuqina kokuqina (HRC 42-44) kwiibhetshi zeeyunithi ezili-120. Akukho hlengahlengiso kwibhetshi ukuya kwibhetshi. Akukho "izibonelelo zohlengahlengiso" kumatshini wokugqibela. Ukuziphatha okuphindaphindiweyo kwe-metallurgical, kuqinisekiswe ngohlalutyo lwe-spectral kunye novavanyo lwe-tensile nge-ASTM E8 / E23.
Xa ukuMachining kungakwazi ukulungisa oko kuphosakele
Ezinye iinjineli zicinga ukuba i-CNC inokubuyekeza izinto ezingachanekanga. Akunakwenzeka-hayi kwiindlela zokunxiba eziphezulu. Qwalasela i-shaft roller esembindini yewintshi yemoto yobunjineli: 42CrMo4 substrate, induction-hardened OD, 0.8 µm Ra finish. Ukuba i-ID ye-as-cast inamaqela e-porosity kufuphi nesihlalo sokuthwala, i-machining iveza i-voids. Ukusila phezu komhlaba kudala iintanda ezincinci. Inxalenye iyasilela kwi-37% yobomi bomjikelo olinganisiweyo. Siyibambile le nto ngexesha lohlalutyo lokusilela ngokubambisana kunye nomakhi wezixhobo zemigodi yaseMzantsi-mpuma Asia. Umboneleli wabo wangaphambili uhanjiswe "ngaphakathi kokunyamezela umzobo" -kodwa waphoswa yinkcazo yeporosity engcwatywe kwiSihlomelo B se-ISO 4990 iKlasi yesi-2.
Isisombululo sethu ibingengomatshini ongqongqo. Kwakuhlengahlengiswa inkqubo yokunyuka, ukutshintshela kwi-ceramic-coated molds, kunye nokongeza ukuhlolwa kwe-ultrasonic kwi-100% yamacandelo abalulekileyo. Isiphumo: iziphene zero zangaphakathi kwiiyunithi ze-1,240 zithunyelwe. Ukunyuka kweendleko? 6.3%. Ukunciphisa ixesha lokuphumla? 100% ngaphezulu kweenyanga ezili-18.
Iindidi ezine. Umgangatho omnye ongaxoxiswana ngawo.
Sijolisa ngokukodwa kwiintsapho ezine zamalungu-kuba ubunzulu bubetha ububanzi kwizicelo ezibalulekileyo zobuthunywa:
- Ukuphoswa kwentsimbi: I-ASTM A48 yeBanga le-30B yezindlu ze-valve-high-pressure valves-ivavanywe kwi-1.5 × ingcinezelo yokusebenza kunye nokuvuza kwe-zero
- Intsimbi kunye neesanti zentsimbi: I-AISI 316L iziseko zempompo kunye ne-delta ferrite elawulwayo (3-8%) yengqibelelo ye-weld
- Amacandelo e-cobalt-nickel alloyImilomo ye-AMS 5387 eqinisekisiweyo ngokwe-ASTM F3062 yokumelana nokhukuliseko kwinkonzo yodaka oluludaka
- Ukuphoswa ngoomatshini be-CNC: Iindawo ezixubeneyo ezifana nezindlu zesilinda apho iikhora zotyalo-mali zenza ukuba iikhonto zangaphakathi zingenzeki ngesanti yodwa.
Lonke udidi lwabelana ngeprothokholi enye: ukulandeleka okupheleleyo. Inani ngalinye lobushushu lidibanisa kwii-certs zezinto eziluhlaza, iingodo ezigalelayo, iingxelo ze-NDT, kunye nedatha yokugqibela ye-CMM. Akukho "isishwankathelo sebhetshi." Akukho "isampulu emele." Ukuba inxalenye yakho iyasilela, ufumana irekhodi elichanekileyo-kungekhona ukwakhiwa kwakhona.
Ukuthembeka akunikezelwa. Yenziwe ngobuNjineli-Emva koko Iqinisekisiwe.
“Umthengisi onesiqinisekiso” uthetha kancinane ukuba ngaba uhlolo lwenzeka kuphela kwirisithi yesango kunye nokuthunyelwa kokugqibela. Sifakela ulawulo lomgangatho kwizigaba ezintathu ezingenakuxoxisana: ukuqinisekiswa kwezinto ezingenayo (i-OES + PMI), kwi-process dimensional checks usebenzisa i-Zeiss CONTURA G2 CMMs kunye neendlela eziqhelekileyo ze-GD & T, kunye nokuqinisekiswa okusebenzayo-njengemizimba yokuvavanya uxinzelelo kwi-bar ye-220 kwi-30 imizuzu kunye ne-helium ukuvuza ukubonwa kwe-1 ×⁶
Oku asikobunjineli obugqithisileyo. Kukunciphisa umngcipheko. Xa i-European hydraulic distributor idinga inkxaso ye-24 / 7 yee-odolo zokutshintshwa ngokukhawuleza, ukuhamba kwethu okuncinci kunye nokucwangciswa kwemveliso ehleliweyo kunqumle iprototype-to-first-first-shiptime time ukusuka kwiiveki ze-14 ukuya kwi-8.6-kunye ne-zero concessions kwi-AMS 2269 imida yokwakheka kweekhemikhali okanye i-ASTM E165 iimfuno zokungena kwamanzi.
Amacandelo okuphosa akumgangatho ophezulu asombulula iingxaki zokwenyani: i-corrosion kwindawo engaselunxwemeni, ukothuka kwe-thermal kwiimpompo ze-geothermal, ukunxiba okubangelwa ngamasuntswana kwiinkqubo ze-sement slurry. Azikho ukuzalisa ibhili yezixhobo. Zikhona ukugcina iinkqubo zisebenza-xa ukusilela ayisiyiyo inketho. Oko kuqala ngokuphatha ukuphosa kungekhona njengenyathelo kwimveliso, kodwa njengesiseko sokuthembeka ngokwayo. Ukufuna izicelo zemizi-mveliso, loo mahluko ayibobuchwephesha. Iyasebenza.
