Mumamva mphete ya valve ndipo anthu ambiri, ngakhale ena ogula, amajambula chotsuka chosavuta chosindikizidwa. Ndiko kulakwitsa koyamba. M'malo mwake, mpheteyo ndiye cholumikizira cha makina onse osindikizira mu swing kapena valavu yowunikira. Maonekedwe ake a geometry, kukhulupirika kwazinthu, ndi kumaliza kwake kumayang'anira mwachindunji ngati mutsekeredwa kapena kubweza kwanthawi yayitali, kokwera mtengo. Ndawona ma projekiti ambiri pomwe gulu la valve lidawoneka bwino, koma mpheteyo idawonedwa ngati chinthu chamtengo wapatali, zomwe zidapangitsa kulephera msanga. Si mphete chabe; ndicho chisindikizo cholondola.
The Core Function ndi Zovuta Zofanana
Ntchito yake ikuwoneka yowongoka: kupereka malo osindikizira ofananirako kuti diski kapena mbale zigwirizane nazo pamene kuthamanga kwasintha. Koma nuance ili mu yunifolomu gawo. Mphete yomwe yatuluka pang'ono-titi, kupitirira 0.05mm kulolerana pa valve 10-inchi-sidzasindikiza. Ipanga njira ya media, yomwe pamapampu imatha kuyambitsa nyundo yamadzi, ndipo mizere yopangira ingayambitse kuipitsidwa kapena kutsika kwamphamvu.
Vuto lomwe ndimakumana nalo kwambiri ndikungoganiza kuti kuuma ndiye chinthu choyambirira. Zedi, mufunika zinthu zolimba kuposa chimbale kuti mupewe kuyika. Koma mphete yolimba kwambiri, yonyezimira, makamaka pamasewera oyendetsa njinga zamoto kapena kutentha, imatha kusweka. Ndikukumbukira nkhani ndi kasitomala ntchito muyezo mpweya mpweya mphete mu nthunzi condensate mzere; Kutentha kwa kutentha kunapangitsa kuti tsitsi likhale long'ambika pamaso pa mpando mkati mwa miyezi. Kukonza sikunali chinthu cholimba, koma cholimba kwambiri chokhala ndi mphamvu zotentha kwambiri.
Kuwongolera kwina ndiko kumaliza. Kupukuta pagalasi sikumakhala bwino nthawi zonse. Pazisindikizo zofewa kapena ma discs okutidwa ndi elastomer, mumafunikira mawonekedwe owongolera - mtengo wake wa Ra - kuti chisindikizocho chiluma pang'ono osang'ambika. Malo osalala bwino nthawi zina amatha kutsetsereka ndi kutayikira pansi pa zovuta zosiyanasiyana.
Kusankha Zinthu Zofunika: Zonse Zikukhudza Utumiki
Apa ndipamene zaka zosamvetseka za 30 zoyambira zidali ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd. sonyeza mtengo wawo. Kuponya mphete iyi sikutanthauza kuthira zitsulo mu nkhungu; ndi za kuwongolera kapangidwe kambewu kuti ateteze kupindika pansi pa katundu. Pakugwiritsa ntchito madzi wamba, chitsulo chabwino cha ductile kapena chitsulo chimagwira ntchito. Koma mukangolowa m'dera lotentha kapena lotentha kwambiri, masewerawa amasintha.
Tinagwira ntchito yokhudzana ndi mzere wa mankhwala okhala ndi acidic pang'ono. Choyambirira chinali cha mphete zachitsulo zosapanga dzimbiri 304. Zinaoneka zomveka. Komabe, dzimbiri zogwetsera zidayamba pankhope yokhalapo patangopita nthawi yochepa. Kusanthula kulephera kunalozera ku ming'alu ya mng'alu pamlingo wa microscopic. Yankho, lomwe tidapanga mogwirizana ndi gulu lawo lopanga makina, linali losinthira ku 316L yokhala ndi mpweya wochepa kwambiri ndikufotokozera njira yothetsera kuponyera pambuyo poponya kuti apititse patsogolo kukana kwa dzimbiri. Kusiyana kwa moyo wautali kunali kwakukulu.
Ukadaulo wawo wama aloyi apadera, monga opangidwa ndi faifi tambala (ganizani kuti Inconel 625) kapena ma aloyi opangidwa ndi cobalt (monga Stellite 6), ndiwofunikira kwambiri pazantchito. Kwa makina opangira madzi opopera othamanga kwambiri komwe kukokoloka kwa cavitation ndikupha, tidaphimba nkhope ya mphete yachitsulo ya kaboni ndi Stetellite pogwiritsa ntchito njira yolondola yoyika. Izi zinatipangitsa kulimba kwachitsulo chokhala ndi malo olimba modabwitsa, osakokoloka. Ndi njira zosakanizidwazi zomwe zimathetsa zovuta zenizeni padziko lapansi.
Kupanga Nuances: Casting ndi Machining Interplay
Ulendo wochoka kumasewera mpaka kumapeto fufuzani mphete ya valve ndizovuta. Kujambula kwapafupi ndi ukonde kuchokera ku nkhungu yodalirika kapena njira yopangira ndalama, monga momwe QSY imagwira ntchito, kumachepetsa malipiro a makina. Izi ndizofunikira pazinthu monga zitsulo zosapanga dzimbiri kapena aloyi, komwe mukufuna kusunga zinthu zakuthupi ndikuchepetsa zinyalala. Kuchotsa theka la inchi ya katundu ku aloyi yolimba sikungowononga nthawi ya makina; zimatha kuyambitsa kupsinjika.
Mayendedwe a makina amafunikira. Inu simungakhoze kungozikhwekhwereza izo ndi kumakomana nazo izo. Zomwe zimakwera - kaya ndi thumba lofikira atolankhani kapena posungira ulusi - ziyenera kupangidwa kaye, kukhazikitsa datum yanu. Kenako, ndipo pokhapo, mumamaliza nkhope yosindikiza yovuta. Ndawonapo mphete pomwe dongosololi lidasinthidwa, zomwe zidapangitsa kuti pakhale malo okongola osindikizira omwe amafanana bwino ndi chilichonse, zomwe zimapangitsa kuti ma valve asamayende bwino.
Kusasinthika kwa makina a CNC sikungakambirane. Pamaoda a batch, kuthekera kwa sitolo kukhala ndi kulolerana pakati pa zidutswa mazana ndizomwe zimalekanitsa chigawo chogwira ntchito ndi chovuta. Kuyang'ana pakati pa OD, nkhope yokhala pansi, ndi zina zilizonse zosungira nthawi zambiri zimamanyalanyazidwa pazithunzi koma ndizofunikira ngakhale kupsinjika ndi kusindikiza moyo. Wokondedwa wabwino samangopempha kujambula; adzafunsa za kamangidwe ka valve, mtundu wa chimbale, ndi kuthamanga kwa opaleshoni kuti alangize za kulolerana kosaneneka kumeneku.
Real-World Application ndi Kulephera Kusanthula
Ndiroleni ine ndifotokoze enieni mutu. Malo opangira magetsi anali ndi kutayikira kosalekeza m'mavavu ake oyendera madzi oziziritsa. Mavavu adakonzedwanso ndi ma disks atsopano, koma oyambirira fufuzani mphete za valve adangopezedwa mopepuka. Kutayikirako kunapitilira. Poyang'aniridwa, nkhope yokhala ndi mphete idawonetsa kavalidwe kakang'ono, kokhala ngati mbale, mwina kuya kwa 0.1mm chapakati. Zinali zosaoneka ndi maso koma zokwanira kuthyola chisindikizocho. Chifukwa chake? Mphete zoyambilira sizinali zowumitsidwa, ndipo zaka zakukhudzidwa kwa ma disc zidapangitsa kuti pulasitiki iwonongeke. Lapping inangopukutira mawonekedwe opunduka. Kukonzekera koyenera kunali kusintha mphetezo ndi zolimba. Phunziro: nthawi zonse muziyang'ana mphete kuti muwone kuphwanyidwa ndi mawonekedwe a pamwamba, osati zokanda pamwamba.
Muzochitika zina, kwa dongosolo la ballast la m'madzi, mphetezo zinatchulidwa mu duplex zitsulo zosapanga dzimbiri kuti zisamawonongeke. Iwo analephera msanga chifukwa cha galling-chimbale akanati micro-kuwotcherera kuti mphete pansi pa kupsyinjika. Nkhani inali yakuti ma disc onse ndi mphete zinali zolimba zofanana ndi aloyi. Kukonzekera kunali kufotokozera zinthu zosiyana, zogwirizana ndi diski (aloyi yamkuwa) kuteteza kuvala zomatira, ndikusunga mphete ya duplex kuti thupi lake lisawonongeke. Kuyanjanitsa zinthu ndikofunika monga momwe zinthu zilili.
Izi sizongoganizira chabe. Ndiwo mtundu wamavuto omwe amadzetsa kuyimba foni nthawi ya 2 koloko. Tsamba lodziwika nthawi zambiri silifotokoza zochitika izi, ndichifukwa chake zokumana nazo kuchokera kwa akatswiri odziwa ntchito zakale komanso akatswiri opanga zinthu omwe awona zolephera izi - monga gulu lomwe limayang'anira madongosolo ovuta pamalo ngati. tsngtaocnc.com—ndi wamtengo wapatali. Iwo sali ongotengera madongosolo; iwo ndi othetsa mavuto omwe amamvetsetsa kuti gawo liyenera kukhala ndi moyo mu dongosolo, osati kungokumana ndi kusindikiza.
Malingaliro Amtsogolo ndi Malingaliro Omaliza
Kuyang'ana m'tsogolo, kuphatikiza kwa mphete zopanda zitsulo kapena zokutira kukukula. Mphete zokhala ndi PTFE kapena zokutira za ceramic za ntchito zoyera kwambiri kapena zotukira kwambiri zikuchulukirachulukira. Vutoli limasintha kuchoka kuzinthu zambiri kupita ku kukhulupirika komatira komanso kuyanjana kwamafuta pakati pa zokutira ndi gawo lapansi lachitsulo. Maziko oponyera ndi makina amayenera kukhala opanda cholakwika kuti zokutira izi zimamatira bwino.
Kuphatikiza apo, kukwera kwa zopangira zowonjezera kumatha kubweretsa mayankho a mphete zosindikizidwa zokhala ndi mayendedwe ozizirira mkati mwa mavavu otenthetsera kwambiri, ngakhale pakadali pano, makina achikhalidwe komanso makina a CNC amapereka kuphatikiza kwabwino kwambiri kwamapangidwe, kukwera mtengo, komanso kupanga voliyumu pamafakitale ambiri.
Chifukwa chake, mukamaliza kufotokozera kapena kutsata a fufuzani mphete ya valve, kupitirira nambala ya gawo. Ganizirani za kuzungulira kwa ntchito yonse: madzimadzi, kusinthasintha kwa kutentha, ma spikes amphamvu, ma frequency ozungulira. Kenako, gwirizanani ndi wopanga yemwe kuya kwake kumawonekera m'mafunso awo, osati mndandanda wawo wokha. Cholinga chake ndi chakuti mpheteyo iiwale-kuchita modalirika kotero kuti sichikhala chifukwa cha dongosolo la ntchito. Ndicho chizindikiro cha chigawo chomwe chinamveka, osati kungopangidwa.
