Xa inkqubo yokutsala amanzi ingasebenzi phantsi koxinzelelo, xa izindlu zempompo ziqhekeka emva kweenyanga ezili-18—kungekhona iminyaka eli-10—yaye xa imingxuma yeewinch ibamba uthuli lwemigodi, unobangela osisiseko awufane uyilwe. Kukunxitywa kokumelana. Akukho "kulunga ngokwaneleyo" ukuxhathisa ukunxiba. Hayi "i-alloy esemgangathweni" yokumelana nokunxiba. Uhlobo olubambe uzinzo lwe-dimensional kwi-220 MPa, luxhathisa i-galling kwi-slurry e-abrasive, kwaye iyasinda kwibhayisikile eshushu ngaphandle kwe-microcracking. Yiyo loo nto iinjineli kulo lonke elaseMntla Melika, eJamani, naseSingapore zingakhangeli nje *iindawo ezikwaziyo ukunxiba*. Bakhangela a umzi-mveliso wamalungu angagugiyo ngoqeqesho oluqinisekisiweyo lwe-metallurgical-hayi nje amandla omatshini.
Ubuchule bezinto eziphathekayo abunakuzikhethela-yinto yokuqala yokukhangela
Siye sabona iiprojekthi ezininzi kakhulu zivaliwe kwinqanaba lokuphononongwa kwezinto: i-cobalt-nickel nozzle yaliwe ngenxa yokwahlulwa kwe-carbon off-spec; i-AMS 5387 yezindlu zempompo ezisilelayo kuvavanyo lwesitshizi setyuwa ngenxa yokungahambelani kokusabela kokunyanga ubushushu; iplagi ye-T800 ye-alloy ebonisa ukhukuliseko lwangaphambi kwexesha ngenxa yokuba i-microstructure ye-as-cast ayinayo i-carbide dispersion. Ezi ayizizo iimpazamo zokuvelisa. Zizikhewu zobuchule bezinto eziphathekayo. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., iialloyi ezisekwe kwicobalt “aziphathwa.” Ziyalawulwa-ngoncedo oluqinisekisiweyo lwemathiriyeli ekrwada, ukulandelelwa kwembali yobushushu elungelelanisiweyo, kunye nokuqinisekiswa kwe-batch-level spectrographic. Yonke i-AMS 5387 yokuphosa iqala ngohlalutyo lwenyibilika olufakwe ngokuchasene ne-ASTM A970. Ilungu ngalinye le-T800 lifumana imephu yobulukhuni obuncinci obusemva komatshini kumacandelo amathathu anqamlezayo. Oku akukho overkill. Yindlela oqinisekisa ngayo i-48 HRC ingqibelelo yomphezulu kwi-12-mm-diameter cobalt alloy nozzle tip-ngaphandle kokuncama ukuqina okungundoqo.
Ukudityaniswa okuthe nkqo kuthetha ukuba akukho lahleko yezandla-iinguqu ezilawulwayo nje
Abanye ababoneleli bakhuphela ngaphandle. Abanye oomatshini bangaphandle. Ukugqitywa kwemithombo embalwa yangaphandle. I-handoff nganye isopha ngokuchanekileyo: ukuguqulwa kobushushu phakathi kwamazwe afakwe kunye noomatshini, ilahleko yengqibelelo yomphezulu ngexesha lokusila okwesibini, ukungahambi kakuhle kwe-GD&T ekulungisweni kwakhona. I-QINGDAO QIANGSENYUAN isebenza phantsi kophahla olulodwa-i-sand casting, i-investment casting, i-multi-axis CNC (kubandakanywa ne-5-axis contouring ye-volutes yempompo yangaphakathi), unyango lokushisa, kunye nokugqiba umphezulu njenge-HVOF okanye ukugaya ngokuchanekileyo. Xa indlu ye-piston pump cylinder ifuna i-± 0.015 mm cylindricity kwi-320-mm bore * kunye * ne-63 Ra umphezulu ogqityiweyo kwiindawo zokutywinwa ezibalulekileyo, loo khonkco yokunyamezela ihlala ngaphakathi. Akukho mthengisi wangaphandle otolika "umphezulu obalulekileyo" ngokwahlukileyo. Akukho kulibaziseka kwamalungiselelo okuphazamisa ukukhululeka koxinzelelo lwe-thermal. Isiphumo? Inxalenye efika ilungele uvavanyo olusebenzayo-hayi ukuphinda usebenze.
Ugxininiso lweDomain luzisa ingqiqo yobunjineli-hayi imizobo kuphela
"Senza iindawo ezikwaziyo ukunxiba" ayicacanga. "Thina iivalvu zoxinzelelo lweenjineli ze-high-cycle manifold hydraulic manifolds ezisebenza kwi-350 bar, izindlu ze-cylinder zeempompo zodaka ezintathu eziphethe i-40% yesanti-by-volume slurry, kunye ne-winch center shaft rollers kwii-50-toni zezithuthi zobunjineli ezisebenza iiyure ezingama-22 / ngosuku kwi -30 ° C ukuya + 60 ° C esebenzayo i-ambient. Oku kukodwa kubumba yonke into: isicwangciso sendlela yesixhobo (i-high-feed milling vs. Ukucotha-pass finishing for cobalt alloys), inspection protocol (CMM probing sequence optimized for the thin-walled valve bodies), nkqu nokupakishwa (i-vibration-dampened crating for cast cast iron pump foundations). Abathengi abasithumeli iifayile zeCAD kunye nethemba. Basithumelela iingxelo zokungaphumeleli, imijikelo yomsebenzi, i-specs yekhemistri ye-fluid-kwaye siphendula ngeengcebiso zebakala lezinto eziphathekayo, iifestile zexesha lokunciphisa uxinzelelo, kunye neefowuni ze-GD & T ezibonisa ukulayisha kwehlabathi lokwenyani-kungekhona nje i-ISO 2768.
Ukuthembeka kuqala ngaphambi kokuba i-chip yokuqala ibhabhe
Ukulandeleka akungomsebenzi wamaphepha. Kukwazi ukuba iplagi ye-cobalt alloy kwivalve yokulawula i-oyile ye-offshore yabelana ngenombolo yayo yokuphatha ubushushu kunye nekhuphoni yovavanyo olunzima olugcinwe iminyaka eli-10. Iingxelo ze-CMM ezibotshelelwe kumanani e-serial-number fixtures, imilinganiselo ye-optical eqinisekisiwe ngokuchasene ne-master gauges ilinganiswe ngeveki, kunye nokuhlolwa kokugqibela okubonakalayo okwenziwa phantsi kwe-1000-lux ukukhanya kwe-LED kunye ne-10x yokukhulisa ukukhangela isiphene somgangatho. “Asiyifikeleli imigangatho.” Sizifake: Ukulawulwa kwenkqubo ye-ISO 9001, ukuqinisekiswa kwe-ASME B16.34-ehambelanayo ne-valve yomzimba, kunye namaxwebhu e-PPAP axhomekeke kumthengi-kuquka iziqinisekiso zezinto eziphathekayo, iingxelo ze-NDT, kunye neerekhodi zovavanyo olusebenzayo. Xa amaxesha okuhanjiswa abalulekile-njengoko besenza kwiindibano zempompo ye-retrofit okanye ukutshintshwa kwe-winch yongxamiseko-isicwangciso sokuhamba komsebenzi esithambileyo kunye nokucwangciswa kwe-buffer-free gcina iprototype iqhuba kunye neeodolo ezinomthamo ophakathi kwindlela. Akukho ntlawulo zikhawulezayo. Akukho "phantsi kwamandla." Imihla yokuzinikela nje, idibene.
Ixesha lokuphumla kwishishini aliphumelelanga ngokuthengwa ngokukhawuleza. Ikhuselwe ngamalungu angagugi kwangaphambi kwexesha-kuba ukuxhathisa kwabo kunxitywa kubunjineli, kungacingelwanga. Oko kufuna a umzi-mveliso wamalungu angagugiyo eyakhelwe phezu kokuqina kwe-metallurgical, ulawulo oluthe nkqo, i-domain-specific ingqiqo, kunye nokulandeleka okungaqhawukiyo. Ukuba ivalve yakho elandelayo yoxinzelelo, indlu yempompo, okanye i-winch shaft kufuneka iphile ngaphaya kwe-spec-hayi nje ukudibana nayo-qala apho ukuxhathisa kokunxiba kuqala: ukukhetha izinto eziphathekayo, ukuqhubeka kwenkqubo, kunye nokusebenza okubhaliweyo. Ayisosithembiso eso. Yindlela umsebenzi owenziwa ngayo.
