Amalungu ensimbi engenasici awaxhathisi nje umhlwa-abamba uxinzelelo, aphile kwi-abrasion, kwaye agcine uzinzo xa ukusilela ayisiyiyo inketho. Kwiindawo ezininzi ze-hydraulic ezilinganiselwe kwi-350 bar, kwizindlu zempompo ezijikeleza kwi-3,600 RPM phantsi kwe-slurry e-abrasive, okanye kwi-offshore i-winch shafts evezwe ngumoya ogcwele ityuwa kunye ne-cyclic torque-la malungu "akukho mnandi ukuba nawo." Ziiiankile ezibalulekileyo zobuthunywa. Siye sabona iivalvu ziqhekeka ukusuka kwi-chloride-induced stress corrosion cracking kwizityalo ezikuMzantsi-mpuma weAsia. Sithathe indawo yezindlu zesilinda ezijijekileyo emva kweenyanga ezili-18 zokukhwela ibhayisekile eshushu kwiimpompo zebala leoyile kuMntla Merika. Ukungaphumeleli ngakunye kwasifundisa into enye: insimbi engenasici ayikho into ekhethiweyo-sisigqibo senqanaba lenkqubo.
Kutheni Amacandelo eStainless Steel egqwesa ezinye iindlela kwiNkonzo yeHlabathi yokwenyani
I-aluminiyam idla ngokukhawuleza emanzini aneklorini. Intsimbi yeCarbon idinga ukupeyintwa rhoqo-kwaye iyasilela ngentlekele ukuba i-coating is nicked. Iintsimbi eziDuplex ezingenazintsimbi ezifana ne-UNS S32205 zizisa amandla esivuno ngaphezulu kwe-450 MPa ngelixa zixhathisa ukugqobhoza emanzini olwandle. Kodwa amandla kuphela akuqinisekisi ukusebenza. Sivavanya yonke ibhetshi ye-316 yensimbi engenasici kwi-ferrite content (injongo: 4-7%); incinci kakhulu imema ukuqhekeka okushushu ngexesha le-welding, kakhulu kunciphisa ukuqina. Yiyo loo nto abathengi bethu kwiimoto zobunjineli zaseYurophu ii-OEMs zichaza i-ASTM A995 iBanga le-CD4MCu-hayi ngenxa yokuba "ayinabala," kodwa ngenxa yokuba i-microstructure yayo yenqanaba ezimbini isinda ekulayisheni ngokuphindaphindiweyo kwi-winch rollers ngaphandle kokusasazwa kwe-microcrack.
Ukumelana nokubola akuyothiyori. Ilinganiswe kwiiyure zokuvezwa kwetyuwa-spray (ASTM B117), iqinisekiswe ngumfanekiso we-SEM wecandelo elinqamlezileyo lobunzima befilimu yokwenziwa, kwaye yaqinisekiswa kwinkonzo yangempela yolwelo. Xa umenzi wempompo wase-US etshintshile ukusuka kwi-304 ukuya kwi-316 yensimbi engenasici kwimigca yokudlulisa imichiza, ixesha lokuphumla liyehla i-62%-kungekhona ukusuka kumatshini ongcono, kodwa ekupheliseni i-chloride-assisted crevice corrosion kwi-interfaces ye-flange. Umahluko yayingelobakala lengxubevange yodwa. Yayilawulwa unyango lobushushu (isisombululo se-annealing kwi-1040-1120 ° C, ukucima ngokukhawuleza), ulawulo oluqinileyo lokugqiba umphezulu (Ra ≤ 0.8 µm kwiindawo zokutywina), kunye nokulandeleka okugcweleyo ukubuyisela kwi-chemistry enyibilikayo.
Apho iiNdawo zekhathalogu eziMgangatho ziwa mfutshane-kwaye yintoni efunwa ziinjineli
Abanye banokuphikisa ukuba izinto zensimbi ezingenasici ngaphandle kwe-shelf zigcina ixesha kunye neendleko. Kodwa ukuthunyelwa kwehlabathi lokwenyani kuxela elinye ibali. Umsasazi wevalve yaseJamani esebenza njenge-hydraulic valve wakha wafumana imizimba ye-316L yegeneric kwimijikelezo yomqhubi woxinzelelo oluphezulu-kuphela ukufumanisa i-porosity yangaphakathi engahambelaniyo emva kovavanyo loxinzelelo kwi-420 bar. Ukuvuza akubonakalanga kumatywina, kodwa ngaphaya komphezulu ongenanto kufutshane nemivalo yesango. Ukulungiswa kwabo? Ukuyila ngokutsha inkqubo yokufaka i-casting kunye nokutshintshela kumacandelo otyalo-mali kunye nokuhlolwa kwe-X-ray nge-ASTM E94 nganye. Ayibobunjineli obugqithisileyo. Leyo yifiziksi.
Sihlala sidibana neemfuno ezintathu ezingaxoxisiyo iinjineli aziyi kuzifumana kwiincwadana:
- Uzinzo lweDimensional kwimijikelo ye-thermal: Izindlu zesilinda kufuneka zibambe ± 0.015 mm ukunyamezela phakathi kwe -20 ° C kunye + 120 ° C - eziphunyezwe ngokusebenzisa i-annealing yokunciphisa uxinzelelo emva komatshini olukhuni, emva koko i-CNC yokugqibela igqitywe kwiqondo lokushisa elizinzileyo.
- Ukunyaniseka kweMicrostructure kwii-concentrators zoxinzelelo: Ukutshintshwa kweRadiused kwi-piston pump manifolds kufuna ukudubula-peening post-machining ukuze kubangele uxinzelelo oluphezulu lwentsalela-ibonakaliswe ukwandisa ubomi bokukhathala nge-3.2 × kuvavanyo olukhawulezayo lobomi.
- Umgangatho osebenzayo womphezulu ngaphaya kweRa: Imiphezulu yokutywina idinga ukubala okuphakamileyo okulawulwayo (iPc> 200/mm) kunye nomlinganiselo weplateau (Rpk <0.2 µm)—hayi nje uburhabaxa obuphakathi—ukuqinisekisa ukuthotyelwa kwetywina le-elastomer phantsi komthwalo oguqukayo.
Ukuziphatha koMveliso Luphawu olungabonwayo
Unokucacisa i-316 yensimbi engenasici-kodwa ngaphandle kokulawula inkqubo, ufumana ukusebenza okuguquguqukayo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Zonke izinto zensimbi ezingenasici zidlula kwiindawo zokuhlola ezifunekayo ezintlanu: isiqinisekiso sezinto ezingenayo ezingenayo (iingxelo zovavanyo lwe-mill kunye nokulandelelwa kwenani lobushushu), ukuqinisekiswa kwe-CMM kwinkqubo ebalulekileyo ye-GD & T datums, isampuli ze-metallographic ezisebenzayo nge-ASTM × 3, kunye noxinzelelo olubonakalayo lwe-ASTM E3, i-5 ye-5. ukuhlolwa phantsi kwe-10 × ukwandiswa kokuyeka umphezulu. Azikho iinqanawa zebhetshi ngaphandle koxwebhu olupheleleyo-kubandakanya ukuqina kwemephu kwiindawo ezinqamlezileyo zokuphosa.
Olu qeqesho lubaluleke kakhulu apho imigangatho iphela kwaye iqala ukusetyenziswa. I-cobalt-alloy nozzle (i-AMS 5387) inokwabelana ngokuxhathisa kwensimbi engenasici-kodwa ubuchule bayo bufuna iindlela zesixhobo ezikhethekileyo, ukuhanjiswa kwe-cryogenic epholileyo, kunye nokulungiswa kwe-vibration-damped. Siye sabona iivenkile zizama ukucola izinto ezisekwe kwi-T800 kwii-VMC eziqhelekileyo-okukhokelela ekuqhekekeni kwesixhobo kwangaphambi kwexesha kunye nokuqhekeka komhlaba ongaphantsi komhlaba. Isisombululo sethu? I-torque ephezulu enikezelweyo, amaziko omatshini we-RPM aphantsi anexesha langempela lokubeka iliso lomthwalo we-spindle kunye nokulawula ukutya okuguquguqukayo. Le nxalenye ibonakala ifana kumbhalo-kodwa ubomi bayo bokudinwa buhluka ngokwemiyalelo yobukhulu.
Ukukhetha iqabane elilungileyo kuthetha ukubuza imibuzo echanekileyo
Buza umthengisi wakho: Ngaba bayayiqinisekisa i-porosity nge-CT yoshishino-kungekhona nje ukungena kwidayi? Ngaba banokubamba i-±0.005 mm yendawo yokwenyani kwi-Ø12 mm bores eqelelene nge-320 mm kwi-santi-cast manifold? Ngaba bagcina iziqinisekiso zezinto eziphathekayo iminyaka eyi-10-okanye de zithunyelwe? Oku “ayikho “ukwazi kakuhle”. Bangumahluko phakathi kwecandelo elihlala iiyure zokusebenza ezingama-5,000 kunye nelinye elingaphumeleliyo kwi-800.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha amacandelo ensimbi engenasici kwindawo apho ulungelelwaniso luthetha ukuvalwa, umngcipheko wokhuseleko, okanye ukungathotyelwa kwemithetho. Indawo yabo ehambelana ne-ISO iphatha yonke into ukusuka kwiprototype yokutyalomali ukuya kwimveliso ye-CNC ephakathi-kunye nempendulo epheleleyo yoyilo-ukwenziwa kokwenziwa ngaphambi kokusika isinyithi sokuqala. Abathengisi iinxalenye. Basombulula iindlela zokungaphumeleli zokusebenza-ngaphambi kokuba zenzeke.
Ngenxa yokuba kwizicelo zamashishini, ukuqina akulinganiswa kwiminyaka. Ilinganiswe kwixesha elingaphazamisekiyo, amazinga okuhamba okuhambelanayo, kunye neziganeko zero zero ezingacwangciswanga. Yiloo nto ehanjiswa ngamacandelo ensimbi-xa yenziwe ngobunjineli, ayichazwanga nje.
