Xa impompo ye-hydraulic isilela phantsi koxinzelelo lwe-350-bar, umenzi wecala unqabile ukuba abe yindlu okanye itywina-yinto Iplagi yeStellite. Hayi nje nayiphi na iplagi. Enye ene-0.005 mm concentricity echanekileyo, i-AMS 5387-ethobela i-cobalt matrix, kunye ne-zero micro-cracks emva konyango lobushushu. Yiyo loo nto iinjineli zaseHouston, eHamburg, naseSingapore zingazikhangeli “iiplagi ze-cobalt alloy.” Bakhangela a Umzi-mveliso weplagi weStellite ukuba iinqanawa iinxalenye-hayi izithembiso.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inike loo malungu ukusukela ngo-2012. Ayiveli kwikhathalogu. Ukusuka kuhlalutyo lokungaphumeleli kwehlabathi lokwenyani: imilomo eqhekekileyo kwiimpompo zenaliti engaselunxwemeni, ukugalela kwi-winch center shaft rollers kwiimoto zobunjineli zodidi lwe-Arctic, ukunxitywa kwangaphambi kwexesha kwizindlu zomjikelo wepiston wepompo yepompo. Siyibonile yonke imo yokungaphumeleli-ke sisebenza ngomatshini zonke iiplagi zeStellite ukuze sizicime ngaphambi kokuba ziqale.
Nantsi into eyahlula iplagi esebenzayo ukusuka kwi-3 × ixesha elide kwinkonzo: ulawulo lwe-metallurgical, kungekhona nje ukuchaneka komatshini. I-T800 esekwe kwi-Cobalt kunye ne-AMS 5387 "ayinzima kumatshini" -ayixoleli * ukuba uphosakele ukwandiswa kwe-thermal ngexesha lokugqiba ukujika okanye ukutsiba isisombululo ngaphambi kokusila. Kwiziko lethu eliqinisekisiweyo le-ISO eQingdao, iplagi nganye yeStellite iqala ngokulandeleka, isitokhwe esiqinisekisiweyo esikrwada-akukho ziqinisekiso zokusila ezamkelweyo ngaphandle kokuqinisekiswa okubonakalayo. Siqhuba imathiriyeli engenayo ngohlalutyo lwe-OES, emva koko sinike iqashiso lobushushu ngalinye i-ID eyodwa engene kwinkqubo yethu ye-ERP. Ukuba umthengi ubika i-anomaly kwiLoti #QS-24-8817, sidonsa iirekhodi zenkqubo epheleleyo: ukuphosa isakhiwo sengqolowa, i-CNC toolpath logs, idatha ye-CMM yokuskena kwiindawo ze-32 zokuhlola, ukuqina komphezulu (Ra ≤ 0.4 µm), kunye nobunzima bokunyanga emva kokushisa (42-48 HRC kwiindawo ezintathu eziqinisekisiweyo). Akukho ngqikelelo. Akukho mndilili webhetshi.
Abanye banokuthi amacandelo e-Stellite angabizi kakhulu. Kodwa iindleko azibalwa kwi-odolo yokuthenga-ilinganiswa ngexesha lokuphumla. Iplagi ye-210 yeedola engaphumeleliyo emva kwee-4,200 cycles ixabisa ngaphezu kwe-plug ye-390 ye-plug elinganiselwe kwi-14,500 imijikelezo xa i-rig yakho ye-offshore ilahlekelwa iiyure ze-18 zexesha lokutofa. Okubi kakhulu: abathengisi begeneric bahlala befaka endaweni yeStellite 6 kunye nemixube ye-cobalt-nickel engabizi kakhulu eswele ukusasazwa kwe-chromium carbide efunekayo kwindawo ezinodaka olunodaka. Asitshintshi. Siyavavanya. Iplagi nganye idlula uvavanyo lwetyuwa-spray (i-ASTM B117, iiyure ezingama-500), uxinzelelo lobungqina be-hydraulic (1.5 × uxinzelelo olusebenzayo, olubanjwe imizuzu eyi-10), kunye nokuhlolwa kwe-ultrasonic nge-ASTM E114. Ukuba ayidlulanga zontathu, iyachithwa-ayiphinda isetyenziswe.
Sikwasombulula oko uninzi lweefektri ezingayi kuvuma: imida yejometri. Iiplagi zeStellite eziqhelekileyo zithatha iifom ezilula ze-cylindrical. Usetyenziso lokwenyani lufuna ibhore eccentric, amagxa okutywina asymmetric, okanye iigrooves ezidityanisiweyo zokupholisa ezifakwe kulungiselelo olufanayo. Amaziko ethu e-5-axis milling aphatha iicontours eziya kufuna ukuseta okuthathu kwenye indawo-ukunciphisa impazamo eyongezelekayo kunye nokuphelisa ukulungiswa kwakhona kokuphazamiseka. Kwimpompo enye ye-OEM yaseYurophu, siyila ngokutsha iplagi ye-Stellite ene-orifice-mbini eneendlela zokuqukuqela ze-offset kunye nobukhulu bodonga obuyi-0.012 mm phakathi kwamazibuko. Umthengisi wokuqala ucaphule iiveki ezili-14 kwaye wala uxanduva lokuqhekeka kokudinwa. Sihambise kwiiveki ze-6-kunye nokuqinisekiswa kwe-strain gauge ebonisa i-22% yoxinzelelo oluphantsi loxinzelelo kwi-junction. Njani? Kuba iqela lethu libandakanya iinjineli zoyilo lwempompo zangaphambili eziye zabuyisela umva ukusilela kwisiza-hayi ukufunda i-GD&T callouts.
A Umzi-mveliso weplagi weStellite ayichazwa ngamaziko ayo okanye amatye okusila. Ichazwa ngendlela ephendula ngayo imibuzo emithathu: Kwenzeka ntoni xa izinto zitshisa ngexesha lokusila kokugqibela? Uhlala phi owona mda ubuthathaka ngokumalunga nokutywinwa? Kwaye-ngokubaluleke kakhulu-umsebenzisi wokugqibela ulinganisa ntoni ebaleni? Siphendula zontathu ngaphambi kokusika i-chip yokuqala. Yiyo loo nto iiplagi zethu zingena kwiivalvu zolawulo lwangaphantsi kwamanzi ezilinganiswe kwi-10,000 psi, iinkqubo zokutofa amafutha ezinoxinzelelo oluphezulu kwiilori ezithutha imigodi, kunye neepompo ezichanekileyo zokudosa ezibamba i-polymer slurries ebolileyo. Akunjalo ngenxa yokuba badibana nee-specs-kodwa ngenxa yokuba basinda kwiimeko ezingabonakaliyo.
Ukujonga phambili, sandisa amandla ethu kwiinkqubo zokwenziwa komatshini wobuxhakaxhaka beendibano ezinkulu zeStellite-ezifana nemizimba yevalvu ye-monolithic enezihlalo ezidityanisiweyo zeplagi eziphoswe kugalelo olunye, emva koko kugqitywe ngokusetwa kwe-NC enye. Umsebenzi wokuqinisekisa uyaqhubeka ukuthotyelwa kwe-API 6A kunye ne-NORSOK M-650. Kodwa ingundoqo ihlala ingatshintshi: akukho nxalenye ishiya iQingdao ngaphandle kokuba iphumelele uvavanyo olusebenzayo olufanayo njengendibano yokugqibela. Ukuba isicelo sakho sifuna ukungabikho kokulalanisa kuthintelo lokhukuliseko, uzinzo lwedimensional, okanye ukungaguquguquki kwesinyithi-iplagi yakho elandelayo yeStellite iqala apha.
