Xa iinjineli zichaza a intsimbi ye-shaft roller kwii-winches ze-hydraulic, iindibano zempompo ze-offshore, okanye izithuthi zobunjineli ezinzima, azigcini nje uku-odola inxalenye-zikhusela ukuzinza kwe-dimensional phantsi kwe-300 + yoxinzelelo lwebar, ukuxhathisa i-pitting kwiindawo ezityebileyo ze-chloride, kunye nokuqinisekisa ukuphuma kwe-zero emva kwemijikelezo ye-10,000. Elo nqanaba lokuthembeka aliveli kubanikezeli begeneric. Ivela kwi-a steel stainless shaft roller factory ngoqeqesho lwe-metallurgical, ulawulo lwenkqubo, kunye nokuqinisekiswa kwehlabathi langempela-kungekhona iincwadana.
Kutheni “intsimbi engatyiwayo” iyodwa ayonelanga—kwaye yintoni eyona nto ibalulekileyo
Abathengi abaninzi bacinga ukuba i-304 okanye i-316 iqinisekisa ukusebenza. Ngokuziqhelanisa, siye sabona ii-shaft rollers zisilela kwi-8,000 cycles-kungekhona kwi-corrosion, kodwa ukusuka kwi-microstructural inconsistency kwindawo yokutya yokuphosa, okanye ukusuka kuxinzelelo olushiyekileyo olushiyekileyo emva kokujika kwe-CNC. I-fektri ye-roller ye-shaft ye-stainless steel stainless ngokwenene kufuneka ilawule izinto ezintathu ezingenakuxoxisana: ukulandelwa kwezinto eziphathekayo kwinombolo yokushisa, ukuqina okulawulwayo ngexesha lesanti okanye ukuphosa utyalo-mali, kunye nokunciphisa uxinzelelo lwasemva komatshini ngaphambi kokusila kokugqibela.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-roller yeshaft yensimbi engenasici iqala nge-AMS 5643 eqinisekisiweyo okanye i-ASTM A743 CF8M billet okanye i-ingot ephosiweyo. Akukho ziqinisekiso zokusila zamkelwa ngaphandle kokutshekishwa ngokupheleleyo kweekhemikhali kwi-OES spectrometry. Senza imephu yokwahlulwa kwekhabhoni kumacandelo anqamlezayo sisebenzisa iprofayili ye-microhardness-kuba umahluko we-5-HRC phakathi komphezulu kunye nombindi uthetha ukuqalisa kokudinwa kwangaphambi kwexesha phantsi komthwalo we-torsional.
Ukudityaniswa okuthe nkqo ngoyena mahluko
Uninzi "lwabavelisi" lukhuphela ngaphandle, ukwenziwa komatshini, kunye nokugqiba ukwahlula abathengisi. Oko kudala izithuba ze-handoff: i-Foundry ayiyazi i-callouts yokugqibela ye-GD & T; ivenkile yomatshini ayikwazi ukulungelelanisa amaxabiso okutya kwi-microstructure echanekileyo njenge-cast; umntu ophatha ubushushu ufumana iinxalenye ngaphandle kokwazi ukuba yeyiphi imimandla ephethe imigangatho ebalulekileyo.
Singabanini bazo zontathu izigaba. Indawo yethu eqinisekisiweyo ye-ISO 9001 iqhuba ukugaywa kwesanti kwiirola ezinobubanzi obukhulu (ukuya kuthi ga kwi-Ø420 mm), utyalo-mali kumajelo okupholisa angaphakathi antsonkothileyo, kunye ne-5-axis CNC machining ngenkqubo yokuhlola ukubamba ± 0.008 mm indawo eyinyani kwiibhore eziphambili. Xa umthengi ethumela umzobo we-winch centre shaft roller enemingxuma yeoli edityanisiweyo kunye namagxa ejenali angenasiphazamiso, iqela lethu liqinisekisa isicwangciso sendlela yesixhobo *phambi* kokwenziwa kokungunda—kungekhona emva kokuhlolwa kwenqaku lokuqala.
Olu hlanganiso luzisa iziphumo ezilinganisekayo: i-42% i-reworks encinci ye-dimensional, i-100% iphinda iphindeke umphezulu we-Ra ≤0.4 µm kwiijenali ze-17-4PH eziqinileyo, kunye nokulandelelwa kweqashiso eligcweleyo ukusuka kwisatifikethi semathiriyeli ekrwada ukuya kwingxelo yokugqibela ye-CMM-ukuhla ukuya kwi-ID yokuphotha esetyenziselwa ukugaya okokugqibela.
Apho iikhathalogu eziMgangatho zisilela khona-kwaye indlela isiko eliSombulula ngayo
Iirola zeshaft zentsimbi ezisemgangathweni zihlala zithatha ukulayisha okumileyo, ubushushu be-ambient, kunye nokuthambisa okufanayo. Izicelo zokwenyani zaphula ezo ngcinga mihla le. Omnye umxhasi woLwandle lwaseNyakatho wabika ngokuphindaphindiweyo i-flange eqhekezayo kwi-subsea pump drive shafts-de kube uhlalutyo lwe-vibration lubonise i-harmonic resonance kwi-1,740 rpm, enomdla kwi-frequency yendalo kwicandelo elingaxhaswanga. I-spec yabo ibiza i-"316 SS," kodwa isisombululo sasifuna ibakala le-17-4PH eliqhelekileyo kunye nokuguga kwe-H900, kunye nokuphazamiseka kwe-0.3 mm okulungelelaniswa ngokuthe ngqo kwi-casting ukuqinisa indawo ye-node.
Thina rhoqo ukusingatha ukutenxa okunjalo: T800 cobalt-based ingxubevange rollers for high-ubushushu iimpompo inaliti umphunga, AMS 5387 cobalt imibhobho edityaniswe kwizindlu roller inkonzo ludaka abrasive, kunye non-standard geometries apho GD & T izitaki idlula ASME Y14.5-2018-2018 imida yokunyamezelwa impazamo yonyamezelo ukuyila. Uphononongo lwethu lobunjineli lubandakanya ingxelo yokwenziwa kokwenziwa ngaphakathi kweeyure ezingama-48, nemizobo eneenkcukacha ezibonisa ezinye iindlela zokubambelela, iimpembelelo zolandelelwano lokuphatha ubushushu, kunye norhwebo olugqityiweyo olungaphezulu kubomi bokunxiba ngokuchasene neendleko.
Ukuhanjiswa kweGlobal ngaphandle kokuNxibelelana kweHlabathi
“Ukuthunyelwa ngenqanawe ngokukhawuleza” akuthethi nto ukuba ukukhukuliseka komyinge kwenzeka phakathi kweprototype kunye namaqashiso emveliso. Sinyanzelisa ukulawulwa kwe-batch engqongqo: ubuninzi be-50 kg ngobushushu kwi-roller encinci ye-diameter, uvavanyo olunyanzelekileyo lwe-ultrasonic kuzo zonke ii-castings > Ø150 mm, kunye nokuhlolwa kokugqibela ngokumalunga ne-gauges echazwe ngumthengi-kungekhona nje ii-calipers.
Umsebenzi wethu onqabileyo uxhasa amaxesha okukhokela okuzinzile: iiveki ze-4 zeeprototypes (kubandakanywa ukuvunywa kwepateni yokuphosa), iiveki ze-6-8 kwii-odolo zevolumu ephakathi (i-50-500 pcs), kunye neefestile zokuhambisa zivaliwe ekungeneni kwe-oda-engaqikelelwanga. Abathengi baseJamani, eCanada, naseSingapore baqinisekisa isivuno sokuqala esingaguqukiyo ngaphezulu kwe-98.7% kwiikota ezintathu ezilandelelanayo. Oko kungaguquguquki kuvela kwiiprothokholi zokuhlola ezibhaliweyo—hayi inkoliseko.
Ukuba isicelo sakho sifuna okungaphezulu kokunganyangeki kwe-corrosion-ukuba ifuna ubomi bokudinwa kwangaphambili, ukuzinza kwe-thermal kwi-400 ° C, okanye i-zero galling kwiimeko zokuqala ezomileyo-ke i-stainless steel shaft roller factory yakho kufuneka ibonise ubuchule kwisayensi yezinto eziphathekayo, kungekhona nje amandla omatshini. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha amacandelo apho ukungaphumeleli kungeyiyo inketho. Ngenxa yokuba kwiinkqubo ze-hydraulic, izithuthi zobunjineli, kunye nezixhobo ze-oyile, i-roller ayikho iinkcukacha. Yingongoma yepivot.
