Iintsimbi zokusahlela zihambisa amandla angenakuthelekiswa nanto, ukuqina, kunye nozinzo lwe-thermal apho ukungaphumeleli kungeyiyo inketho-i-hydraulic manifolds phantsi kwebar ye-350, izindlu zempompo zangaphandle ezivezwe emanzini olwandle kunye ne-santi abrasion, okanye i-winch center shaft rollers kwi-excavators yemigodi ethwele imithwalo yeetoni ezininzi. Ezi azikho nje iinxalenye zetsimbi. Zizigqibo ezithwele umthwalo ezenziwe kwisanti efunyenweyo kwaye ziqinisekisiwe kwiilebhu ze-metrology.
Sibone iiprojekthi ezininzi kakhulu ziphazamiseka xa iinjineli zicacisa "ukuphosa intsimbi" ngaphandle kokucacisa ibakala, imeko yonyango lobushushu, okanye iimfuno ezibalulekileyo zendawo. Umzimba wevalve ye-ASTM A216 WCB unokudlula i-hydrotest-kodwa i-crack ngexesha lokuhamba ngebhayisikile ye-thermal ukuba iqhelekile endaweni yokucima kunye nokufudumala. Indlu yesilinda yempompo yepiston eyenziwe ngomatshini ukusuka kwibha eyenziweyo yonga ixesha kodwa incama ukuxhathisa kokudinwa kwe-isotropic xa kuthelekiswa nokugaywa ngokufanelekileyo kwesango kunye ne-post-weld egalelwe ubushushu. Yiyo loo nto iicasts zentsimbi zihlala zingenakuthatyathelwa indawo kwiinkqubo zemizi-mveliso ezibaluleke kakhulu kubuthunywa: zidibanisa ukuqhubeka kolwakhiwo kunye nenkululeko yoyilo akukho ngcibi okanye ukuyilwa okunokuhambelana.
Iinyani ezintathu zobugcisa zahlula intsimbi esebenza kakhulu kwimveliso yemveliso:
- Ulawulo lwe-Metallurgical luqala ngaphambi kokugalelwa. Ukulandelwa kwezinto ezikrwada ayingomaphepha-ziingxelo zovavanyo lwe-batch-specific mill ye-carbon, i-chromium, i-molybdenum, kunye nezinto ezishiyekileyo ezifana nobhedu kunye ne-tin. Siye sakhaba ukushisa okupheleleyo kwe-ASTM A352 LCB ngenxa yokuba ulwahlulo lwesulfure lugqithise i-0.025% kwindawo yokunyuka-engabonakaliyo ngokuhlola okubonakalayo kodwa ibonakaliswe yingozi kwi-low-temperature shock loading.
- Ingqibelelo yomgangatho ixhomekeke ekudityanisweni kwenkqubo-hayi nje ukuphosa. Isiseko sempompo ye-OD eyi-420 mm kufuneka sibambe ±0.15 mm ukungqukuva kwindawo ethwele izihlalo *emva* kokuthomalalisa uxinzelelo, ukwenziwa komatshini, kunye nokuhlolwa kokugqibela. Oko kufuna imodeli yesibonelelo esilungelelanisiweyo, i-gating yokuqinisa umkhombandlela, kunye nokubamba kwe-CNC ukuba ireferensi njenge-datums-ingeyiyo egqityiweyo.
- Umgangatho womphezulu uchaza umsebenzi-hayi ukugqiba. Umbhobho wengxubevange ye-cobalt ye-AMS 5387 ayikhazimliswanga ukuze ibonakale. I-0.8 µm Ra yangaphakathi ibhore iyanciphisa ukhukuliseko olubangelwa yi-turbulence-induced cavitation. Iifayili zayo zangaphandle zithintela uxinzelelo phantsi kwee-spikes zoxinzelelo lwe-cyclic. Umphezulu awuhombisi. Yintsebenzo elinganisiweyo.
Abanye baphikisa ukuba ukuphoswa kotyalo-mali kuzisa isiphelo esingcono somphezulu kunokuphosa isanti-ngoko kutheni usebenzisa isanti kwaphela? Kuba isanti iphatha ubunzima, ijometri, kunye nobunzima bealloy obunyibilikisa iimolds zotyalo-mali. I-220 kg yemoto yobunjineli yewintshi yeshaft roller enamajelo okupholisa angaphakathi kunye ne-asymmetric flanges? Ukugalelwa kwesanti kulawula ukuthambeka kwe-thermal kuwo wonke amacandelo ashinyeneyo; iipateni zotyalo-mali zingagqwesa okanye zitshise. Urhwebo lokwenyani alugqibi ngokuchasene nokuchaneka-ziindleko ezipheleleyo zobunini ngokuchasene nenkqubo enye. Sihlala sidibanisa zombini: imizimba yesanti-cast yesakhiwo kunye nokufakwa kwe-investment-cast kwiindawo zokuguga-emva koko zimatshini njengeyunithi enye yokusebenza.
Olu qeqesho lwe-hybrid lufuna isakhono esithe nkqo. Awunako ukukhupha unyango lobushushu kwaye ulindele ukomelela okuphindaphindwayo kwi-120 mm yodonga. Awunakuthembela kwi-NDT yomntu wesithathu xa uhlolo lwe-ultrasonic kufuneka imephu ye-porosity ngaphakathi kwe-3 mm yendawo yokutywinwa ngomatshini. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke ukuphosa intsimbi idlula kumasango amane angenakuxoxisana: ukuqinisekiswa kwezinto eziluhlaza eziqinisekisiweyo (kunye ne-CoA cross-referenced to heat number), kwi-process CMM scanning kwi-green and post-heat-treat-treat-treat, 100% MPI / UT kwiindawo ezibalulekileyo nge-ASTM E165 / E1444, kunye nokuqinisekiswa kokugqibela kokusebenza-njengokukhangela uxinzelelo lwezindlu kwi-hydraulium ye-hydraulium × 5. 1×10⁻⁶ mbar·L/s ubuntununtunu.
Waba yintoni umphumo? Amacandelo asinda apho abanye badinwe. Iivalvu zoxinzelelo ezisebenza ngokuqhubekayo kwi-200°C kwimigca yomphunga we-geothermal. Izindlu zesilinda ezinyamezela imijikelo yoxinzelelo lwezigidi ezili-15 kwi-subsea hydraulic actuators. Iziseko zempompo ezifunxa ukungcangcazela kwe-torsional ngelixa zigcina ulungelelwaniso ngaphakathi kwe-0.03 mm ngaphezu kobubanzi obuziimitha ezi-3. Ezi ayizizo iinkcazo zethiyori. Ziziphumo eziqinisekisiweyo ebaleni-zibhalwe kwiingxelo zenkonzo ezivela kumaqonga oLwandle oluMntla, iindawo zesanti yeoli yaseAlberta, kunye neenqwelomoya zokutyhoboza zaseMazantsi mpuma eAsia.
Ukujonga phambili, umda awukho nje i-alloys eqinile-kukudityaniswa okuhlakaniphile. Sandisa i-R&D kwiinkqubo ezixutyiweyo zokugalela: ukubethelela iigeji zoxinzelelo ngqo kwizibungu zesanti ukujonga uxinzelelo lokuqina ngexesha lokwenyani; ukusebenzisa i-AI eqhutywa yi-image ye-thermal ukuqikelela i-micro-shrinkage ngaphambi kokuba i-machining iqale; ilungele i-T800 entsha esekwe kwi-cobalt-steel composite kwi-ultra-high-cycle impellers zempompo. Kodwa akukho nanye kwezi zinto zibalulekileyo ukuba ubunyani obuphakathi bulahlekile phakathi komzobo kunye nokuhanjiswa. Yiyo loo nto ukuzinikela kwethu kunamandla kuhlala kungatshintshi: yonke into ukuphosa intsimbi iinqanawa ezinokulandeleka ngokupheleleyo kwezinto, i-GD & T-ehambelanayo neengxelo zokuhlola, kunye nenqaku elilodwa lokuphendula kwezobugcisa-ukusuka kuphononongo lomzobo wokuqala ukuya kuhlalutyo lokungaphumeleli kwentsimi.
