Ukuphula amasiko ukuze kufezwe okungavamile: Ubuchwepheshe bokumboza nge-laser budala "isivikelo esiqinile kakhulu" sama-piston
Embindini wemboni yesimanje – izinhlelo ze-hydraulic kanye ne-fluid – i-plunger, njengengxenye ebalulekile ehambayo, enezakhiwo zayo ezingaphezulu ezinquma ngqo ukuthembeka, ukusebenza kahle, kanye nokuphila kwesevisi yesistimu yonke. Sekuyisikhathi eside, ukuguguleka, ukugqwala, kanye nokukhathala kube yizinselele ezingokwemvelo ezibhekene nezinsimbi zendabuko. Namuhla, singathanda ukwethula kini ubuchwepheshe obuvuselelayo bokuqinisa ubuso: i-laser cladding. Ngezinzuzo zayo eziyinhloko "zokunemba kwezinga le-micrometer" kanye "nokubopha kwe-metallurgical-grade," lobu buchwepheshe buvula isahluko esisha ekuthuthukisweni kokusebenza kwe-plunger.
I. Izinselele Zendabuko: Amaphutha Ekumelaneni Nokuguguleka Komphezulu We-Plunger
I-plunger idlula ezinyakazweni eziphindaphindwayo eziphindaphindwayo ezindaweni ezinengcindezi ephezulu, ezisheshayo, kanye nangaphakathi kwemidiya eyinkimbinkimbi, okuholela ekutheni ubuso bayo buhlale bubhekene nokungqubuzana okukhulu kanye nokushayisana. Ngisho noma yenziwe ngensimbi ye-alloy esezingeni eliphezulu, izinqubo zokwelapha ukushisa zendabuko noma amasu okufaka i-chrome eqinile asenemikhawulo ebalulekile.
Isembozo sincane kakhulu (ngokuvamile
Isembozo kanye nezinto eziyisisekelo ziboshelwe ngomshini kuphela, okwenza kube lula kakhulu ukuhlukanisa.
Inqubo yokufaka i-chrome plating ibhekene nezinselele ezinkulu zokuvikela imvelo.
Izindleko zokushintsha ngokuphelele i-plunger ziphezulu kakhulu, futhi isikhathi sokungasebenzi esiphumelayo siholela ekulahlekelweni okukhulu.
Le mikhawulo ibe yizithiyo ezivelele ezivimbela ukusebenza kwesikhathi eside nokwethembekile kwamaphampu e-plunger.
II. Inguquko Yezobuchwepheshe: Kuyini ukumbozwa nge-laser?
Ukumbozwa nge-laser, okubizwa ngokuthi "i-directional metallurgy," kuyindlela yobunjiniyela obuphambili obusebenzisa imisebe ye-laser enamandla aphezulu ukuncibilikisa ngokushesha izinto ze-alloy ezisebenza kahle kakhulu kanye nobuso bezinto eziyisisekelo, okuvumela ukuqina okusheshayo kanye nokwakheka kwengqimba eqinile, engenama-pore, engenama-crack.
Le nqubo ifana "nokushisela okuqoshiwe okuncane": Ngaphansi kwesiqondiso sohlelo lwe-CNC olunembile, umsebe we-laser uhamba ngqo ngendlela enqunyiwe, "uhlanganisa futhi uthunge" i-nanoscale tungsten carbide, i-cobalt-based, noma i-nickel-based alloy powders ezindaweni ezithile zobuso be-plunger. Ubukhulu besendlalelo se-cladding bungalungiswa ngokuguquguqukayo ngaphakathi kobubanzi obungu-0.2 kuya ku-3.0 mm, okwenza kube lula ukwenza ngokwezifiso ukusebenza - noma ngabe ukuqinisa kuyadingeka, ukuqinisa kusetshenziswa ngokunembile.
III. Kungani ukufakwa nge-laser "kuyinketho engcono" yokuqinisa i-plunger?
Ubulukhuni bukhuphuke kakhulu, kanti ukumelana nokuguguleka nakho kuphindeke kabili.
Ubulukhuni besendlalelo se-laser cladding bungafinyelela ku-HRC 60–70 (cishe i-HV 700–1000), okuphindwe ka-1.5–2 kunokwensimbi ecinyiwe esezingeni eliphezulu kanye nokuphindwe ka-2–3 kunokwezendlalelo zendabuko ze-chromium-plated. Ezivivinyweni ngaphansi kwezimo zokusebenza ezimbi kakhulu, njengalezo ezitholakala ezisekelweni zamalahle kanye namaphampu okubhoboza uwoyela, impilo yesevisi emaphakathi yama-piston ikhuliswa ngo-300%–500%.
Ukubopha kwensimbi kuqinile kakhulu, okuqinisekisa ukuthi ukuxebuka kuvinjelwe ngokuphelele.
Emazingeni okushisa aphezulu, ungqimba lwe-cladding kanye nezinto eziyisisekelo ziyahlangana, zakha indawo yokuguquka kwensimbi cishe ubukhulu obungu-50-100 μm. Amandla okubopha atholakala ngale ndlela angadlula u-80% wamandla ezinto eziyisisekelo uqobo, ngaleyo ndlela kuxazululwe inkinga yokuqhekeka kwe-coating.
Ukwenza ngokwezifiso kanye nemizamo yokulungisa enembile kwenza kube lula ukukhiqiza kabusha ngobuhlakani.
Ukuqinisa kwendawo: Ukuqinisa kusetshenziswa kuphela ezindaweni ezibalulekile njengemichilo yokuvala kanye nezingxenye ezithwala ingcindezi, ngaleyo ndlela konga izindleko.
Umklamo we-gradient: Ufeza i-gradient esebenza kahle kakhulu eqhubekela phambili kusukela ezintweni eziyisisekelo kuya phezulu, equkethe izingqimba zokuqina, ubulukhuni, kanye nokumelana nokuguguleka.
Ukuvuselelwa kwezingxenye ezisetshenzisiwe: Imikhono ye-plunger egugile ilungiswa ngokumbozwa, kubuyiselwe ubukhulu bayo bokuqala futhi kuthuthukiswe ukusebenza kwayo. Izindleko zale nqubo zingama-30% kuya ku-40% kuphela wezindleko zokuthenga izingxenye ezintsha.
Izinqubo zokukhiqiza eziluhlaza: eziya entuthukweni esimeme
Yonke inqubo ayinakho ukungcola kwensimbi esindayo kanye nokuphuma kwamanzi angcolile, futhi izinga lokusetshenziswa kwezinto lidlula u-95%. Lobu ubuchwepheshe bokukhiqiza kabusha obumelela ngempela umqondo wokukhiqiza oluhlaza.
IV. Izixazululo Zesistimu: Ukuguqula izinzuzo zobuchwepheshe zibe yinani lamakhasimende
Kwa-Green Laser Tech, asigcini nje ngokuhlinzeka ngemishini ethuthukisiwe kodwa futhi silwela ukunikeza amakhasimende izixazululo eziphelele zokuqinisa ubuso bama-piston.
Uhlelo lokulungisa kusengaphambili olunembile: Lolu hlelo lusebenzisa inhlanganisela ye-micro-sandblasting kanye nokuhlanza nge-laser ukuqinisekisa ukuthi ubuso be-substrate buhlanzekile ngokuphelele, ngaleyo ndlela kubekwa isisekelo se-cladding yekhwalithi ephezulu.
Ithuluzi lomshini wokumboza ohlakaniphile we-multi-axis: Lenzelwe ngqo izingxenye ezijikelezayo ezifana nama-piston, lifakwe uhlelo lokuphakela ngempuphu oluhambisanayo kanye nohlelo lokulinganisa izinga lokushisa lwesikhathi sangempela, okuvumela ukumboza okufanayo kwezindawo eziyinkimbinkimbi.
Isizindalwazi sezinto ezibonakalayo sinikeza ukwesekwa ngokunikeza amafomula ezinto eziqinisekisiwe ezingaphezu kuka-30, ahlukaniswe ngezigaba ezinkulu ezingu-8, ukuze kuhlangatshezwane nezimo zokusebenza ezahlukahlukene njengokugaya okumanzi, ukugaya okomile, kanye nokuguga kokugqwala.
Uhlelo Lochwepheshe Bezinqubo: Luhlanganisa amakhulu amaphakheji enqubo alungiselelwe kusengaphambili okuhlanganisa i-plunger, ahlanganisa uhla oluphelele lwemikhiqizo - kusukela kuma-valve cores anembile anobubanzi obungu-20 mm kuya kuma-hydraulic cylinder plunger amakhulu anobubanzi obungu-500 mm.
Ukulawulwa kwekhwalithi yenqubo ephelele: Ngokuhlanganisa izinhlelo zokuqapha eziku-inthanethi kanye nokuhlola ungaxhunyiwe ku-inthanethi, kuqinisekiswa ukuthi ukuphambuka kobulukhuni bomkhiqizo kungu-≤3%, ukuphambuka kobukhulu kungu-≤5%, kanye nobukhulu bomphezulu u-Ra kungu-≤0.8μm.
V. Ucwaningo Lwecala Olungokoqobo: Indlela Izinombolo Ezibonisa Ngayo Amandla Oshintsho
Iphrojekthi yokulungisa ukwesekwa kwe-hydraulic yemayini yamalahle
Eqenjini elikhulu lemishini yamalahle yasekhaya, kwalungiswa ama-piston ekholomu angu-φ360mm. Izindleko zokumboza ingxenye ngayinye ngayinye zazicishe zibe yi-yuan engu-12,000. Ngenxa yalokho, impilo yenkonzo yalezi zingxenye yandiswa kusukela ezinyangeni ezingu-8 kuya eminyakeni engaphezu kwemi-3, okwenza ikhasimende likwazi ukonga ama-yuan angaphezu kwezigidi ezingu-4 ezindlekweni zokufaka esikhundleni ngokuhamba kwesikhathi.
