Paunonzwa 'valve cage', kana iwe uchifunga kuti ingori imba yakasimba ye trim, hauna kukanganisa, asi uri kurasikirwa nepoindi. Ndiro gamba risingaverengeki rinotsanangura kutonga, hupenyu hurefu, uye kazhinji, hunhu hwevharuvhu hwese mubasa rakasimba.
Iyo Yakakosha Kusanzwisisa uye Material Reality
Mafungiro akawandisa anobata keji sechinhu chemushonga, achingotarisa chete pazvinhu zvidiki. Ndiyo nhanho yekumhanya yekutadza kukasika. Keji haingovepo kuti ibate zvidimbu; ndicho chinhu chekutanga chinotungamira kuyerera, kudzora velocity, uye kutora iyo brunt yecavitation nekukukurwa. Ndakaona mavharuvhu achitadza nekuti trim yaive Inconel 625 asi keji yaive yakajairwa 316SS yakagezwa mumwedzi mitanhatu, ichisiya plug yakanaka ichitenderera.
Apa ndipo panowanikwa uye machining pedigree yemutengesi inova isingagone kutaurirana. Unoda munhu anonzwisisa kuti kuperera kunotanga mukunyungudika. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakumi matatu emakore emugoko uye kuisa mari, vanowana izvi. Hazvisi zvekungogadzira chimiro; ndezvekuwana imwe homogenous, isina kukanganisa-isina zviyo chimiro mune zvinofarirwa zve duplex simbi kana cobalt-based alloys kubva pakudirwa kwekutanga. A microscopic shrinkage cavity munzira yakaoma yekuyerera ibhomba renguva yekumaka.
Sarudzo pakati pegoko mold nekukandira kwekudyara kwekeji ndeyekutanga kutengeserana-kure. Kune makeji akakura, asina kuomesesa mucarbon kana yakaderera-alloy simbi, shell mold yakasimba uye inodhura-inoshanda. Asi paunenge uchibata neakaomesesa akawanda-maburi madhizaini e-anti-cavitation kana yakaderera-ruzha trims mu super duplex kana Hastelloy, investimendi yekukanda ndiyo nzira chete yekuita kuti iwo mavhesi emukati akatsetseka uye akarurama pasina hupfumi mubasa reEDM. Kugona kwehuviri hweQSY pano mukana unoshanda, uchibvumira kurudziro yechinangwa pane kuita imwe-maitiro-inokodzera-ese maitiro.
Precision Haisi Kungoshivirira Padhirowa
Zvakanaka, saka une ruzha rwekukanda. Zvino basa chairo rinotanga. Kusangana kunotarisana nebhoneti uye plug, concentricity yemaburi ekuyerera, kupera kwemabhori emukati-izvi ndizvo zvinoparadzanisa chikamu kubva kune chiridzwa chaicho. Kusarongeka kudiki pano hakungokonzeresa kubuda; inokonzera asymmetric kuyerera, kusaenzana kupfeka, uye stem kusunga. Ndinoyeuka imwe nyaya ine vharuvhu yekutsikirira-yakadzika apo kutaura uye kupfupikiswa kwehupenyu hwechisimbiso kwakarongedzerwa kumashure kune keji ine chiboro chaive mamicrons mashoma kubva pakati, zvichiita kuti plug igare zvisina kuenzana.
Izvi zvakachena CNC machining ndima, uye inoda zvinopfuura kungoita chitoro chemazuva ano. Zvinoda kugadzirisa uye kuronga kuronga kunoremekedza basa rekupedzisira rechikamu. Iyo machinist inofanirwa kuziva kuti ndeapi mapeji akakosha pakuisa chisimbiso uye kutungamira maringe neayo angori maumbirwo. Chitoro chinongoita zvekugadzira zvimiro chinopotsa aya nuances. Inyanzvi yekugadzira, seizvo QSY inosimbisa, yakakosha pakushandura yakanaka kukanda kuita yakavimbika, yepamusoro-inoshanda chikamu.
Uye ngatitaure nezve iwo maburi ekuyerera. Kuchera maitiro emakomba zviri nyore. Kudhirowa patani uko gomba rega rega rine inowirirana, isina burr-isina mupendero uye chaiyo hydrodynamic angle yekudzora kuyerera kwekoefficient (Cv) uye ruzha? Ndihwo unyanzvi. Kubvisa mari haisi yekufungidzira; idanho rinosungirwa. Bhara rakasununguka rinogona kubvaruka, kufamba pasi perwizi, uye kukanganisa. Ndapedza mazuva ndichigadzirisa kudzoreka kwevharuvhu kuti ndiwane chidimbu chesimbi kubva pachiteshi chekeji chisina kupera chakaiswa mumhete yechigaro.
Iyo Alloy Sarudzo Dilemma: Zviri Context
Mashizha akajeka anoda kuridza Alloy 20 kana Monel sekurapa-zvese. Asi kusarudzwa kwezvinhu zvekeji yevharuvhu inhaurirano pakati pekuora, kukukurwa, kudzvanywa, uye tembiricha. 17-4PH inogona kunge yakakura pakusimba uye kuonda kuri pakati nepakati, asi isarudzo isina kunaka yekuenderera mberi machlorides. Saizvozvo, cobalt-based alloy seStellite 6 inonakidza kune abrasive sevhisi, asi machinability yayo inotyisa uye mutengo wakakwira - unongozvitsanangura kana uchinge wanyatsoida.
Apa ndipo panobhadhara ruzivo rwemutengesi. Chitoro chinogara chichishanda nemaaroni-kubva kusimbi dzakakandwa uye simbi dzekabhoni zvichikwira kuburikidza nenickel-based alloys seInconel 718-inogadzira kunzwa kwematumbo. Vanogona kusundira kumashure pane-over-spec kana kunyevera pamusoro peiyo under-spec. Semuyenzaniso, mune yakavava gasi application (H2S iripo), ichitsanangura yakakwira-kuomarara zvinhu pasina kupisa kwakaringana sulfide stress cracking resistance ndiyo nzira yenjodzi. Keji yacho yaigona kutsemuka zvine njodzi. Mudiwa ane ruzivo anofanira mureza izvozvo.
Ndinorangarira chirongwa chechirimwa chegeothermal apo mvura yacho yaive musanganiswa wakashata wekupisa kwakanyanya, acidity shoma, uye silica yakamiswa. Takamboedza 440C yakaomeswa keji isina tsvina. Yakanyura ikava chubhu isina shapeless mukati megore. Mhinduro yaive shanduko kune yakasarudzika-yakadururwa nickel-chromium-boron alloy ine yepamusoro inopisa kuomarara uye kusaita ngura. Yakanga isiri pane chero yakajairika valve BOM, asi yaive mhinduro chaiyo yeinjiniya. Vatengesi vane advanced alloy ruzivo vanogonesa idzi mhinduro.
Kukundikana seMudzidzisi: Nyaya yeVibrating Valve
Zvimwe zvezvidzidzo zvakanaka zvinobva muzvinhu zvisiri kufamba zvakanaka. Taive nevharuvhu yekudzora pamutsetse wemhepo yakagadzira kuzunguzika kwakanyanya, kwakakwira-frequency. Mucheka wacho waive wakajairwa kage kane ma slots. Diagnostics yainongedzera kuyerera-induced vibration, asi mavhesi aifungidzirwa ari mukati mechikamu.
Pakuchema, takawana dambudziko. Iwo anotsvedza mukeji, nepo ane dimensional akarurama, aive nekashoma se-kukandwa pamusoro pekupedzisira pamipendero yavo yekutevera pachinzvimbo chekugadzirwa muchina wakatsetseka. Izvi zvakagadzira mhepo diki, ine mhirizhonga ichidonha nguva zhinji — mugwagwa wekare weKármán vortex — waienderana nemafambiro ekeji pachayo. Chizarira chaitozviimbira kufa chaiko. Kugadzirisa kwacho kwaive kugadziridzazve mafungu ese emukati ekuyerera kusvika pakupera kwepamusoro, kutyora iyo harmonic. Zvakandidzidzisa kuti kumakeji mune yakakwira-velocity gasi kana sevhisi yemhepo, kupedzisa kwepamusoro panzira dzekuyerera kwakakosha sejometri.
Rudzi urwu rwekugadzirisa matambudziko kazhinji runowira kumugadziri. Ivo havagone kungoita kutsiva, asi kubatsira kuongorora uye kudzokorora dhizaini? Zvinoda mushandirapamwe, ane pfungwa dzeinjiniya pane kungotora-odha.
Kubatanidzwa uye Mufananidzo Mukuru
Pakupedzisira, keji yevharuvhu haimboshanda iri yega. Kuita kwayo kwakasungirirwa papuragi, chigaro, hunde, uye actuator. Keji yakanyatsogadzirwa haibatsiri kana plug isingaenderane neinotungamira nzvimbo neyakajeka. Ichi ndicho chikonzero mamwe mavharuvhu anovimbika akanyanya-sevhisi achibva kune vanogadzira vanodzora iyo yese trim stack kugadzirwa, kuve nechokwadi chakazara kukwana.
Kune vatengesi vechikamu vakaita seQSY, chirevo chakajeka: kunzwisisa gungano kwakakosha. Vanoda kubvunza kuti, Ndeipi plug dhizaini iri kusvirana nayo? Iparabolic, V-port, kana multi-stage dhizaini? Iyo machining specs yekeji yakapetwa nepakati plug yakasiyana neiyo yeanogara-akagara, akakwira-yekudzoreredza dhizaini. Kupa dimensional uye kupedzisa kuenderana kwakawanda mushure mejenya ndiko kunobvumira mavharuvhu anounganidza kuti awane akavimbika, anofungidzira kuita.
Mukupedzisira, kutsanangura kaji yevharuvhu chiitiko mukufunga kwehurongwa. Icho chikamu chemuganho wekumanikidza, mutungamiriri wekuyerera, anti-cavitation mudziyo, uye inotungamira nzira. Kubata kutenga kwayo sechinhu chiri nyore kutenga zvinhu kunorerutsa basa rayo. Unoda sosi inobata simbi, inyanzvi yekugadzira zvinhu, uye, zvakakosha, kunzwisisa mamiriro ehutsinye chikamu ichi chinofanira kurarama mairi. Ndiwo mutsauko pakati pechikamu chinokwana nechikamu chinoshanda.
