Iwe unonzwa cheki mhete yevharuvhu uye vanhu vazhinji, kunyangwe vamwe vari mukutenga, pikicha iri nyore yakadhindwa washer. Ndiko kukanganisa kwekutanga. Muchokwadi, iyo mhete ndiyo linchpin yese yekuisa chisimbiso mune inoswing kana wafer cheki valve. Iyo geometry yayo, kutendeseka kwezvinhu, uye kupedzisa kunonongedza zvakananga kana iwe ukawana kuvharika-kuvharika kana chisingaperi, chinodhura kudonha-kumashure. Ndakaona mapurojekiti akawandisa apo muviri wevharuvhu waifungidzirwa kusvika pakukwana, asi mhete yakabatwa sechinhu chekutengesa, zvichikonzera kukundikana nguva isati yakwana. Haisati ichingova mhete; chinhu chaicho chekuisa chisimbiso.
Iyo Core Basa uye Zvakajairwa Pitfalls
Basa rayo rinoita serakajeka: kupa yunifomu yekuisa chisimbiso pamusoro pedhisiki kana ndiro yekusangana kana kuyerera kwadzoka. Asi iyo nuance iri mune yunifomu chikamu. Mhete yakatombobuda-pafurati - toti, kupfuura 0.05mm kushivirira pane 10-inch valve - haivharike. Ichagadzira nzira yemedia, iyo mumapombi masisitimu anogona kukonzera nyundo yemvura, uye mumitsetse yemaitiro inogona kutungamira mukusvibiswa kana kudonha kwekumanikidza.
Gomba randinosangana naro zvakanyanya kufungidzira kuti kuomarara ndiyo yekutanga fungidziro. Chokwadi, unoda chinhu chakaoma kupfuura dhisiki kuti udzivise kuisirwa. Asi mhete yakanyanya kuoma, ine brittle, kunyanya mu cryogenic kana thermal cycling services, inogona kutsemuka. Ndinoyeuka nyaya nemutengi achishandisa mhete dzesimbi yekabhoni mumutsetse we condensate; kuneta kwemafuta kwakakonzera kutsemuka kwebvudzi pachiso chekugara mukati memwedzi. Kugadzirisa kwanga kusiri chinhu chakaoma, asi chakanyanya kusimba chine zvirinani zvekupisa zvivakwa.
Kumwe kutarisisa ndiko kupera. Girazi regirazi harisi nani nguva dzose. Kune zvisimbiso zvakapfava kana elastomer-coated discs, iwe unotoda inodzorwa pamusoro pemanyorerwo - imwe kukosha Ra - kubvumira chisimbiso kuruma zvishoma pasina kubvaruka. Nzvimbo yakatsetseka yakatsetseka dzimwe nguva inogona kutungamira mukutsvedza uye kuvuza pasi pekumanikidzwa kwakasiyana.
Kusarudzwa Kwezvinhu: Zvese nezveSevhisi
Apa ndipo pakaita 30-odd makore e foundry Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ratidza kukosha kwavo. Kukanda mhete iyi hakusi kwekudira simbi muforoma; zviri pamusoro kudzora zviyo chimiro kudzivirira deformation pasi mutoro. Kune yakajairwa kushandiswa kwemvura, yakanaka mhando ductile iron kana simbi yakakandwa inoshanda. Asi iyo nguva yaunopinda munzvimbo ine corrori kana yakakwirira-tembiricha, mutambo unoshanduka.
Takashanda purojekiti inosanganisira mutsetse wekudosa kemikari une acidic yakapfava. Iyo yekutanga yakatarwa yaive ye304 mhete dzesimbi. Zvaiita sezvine musoro. Nekudaro, kukora kwegomba kwakatanga pachiso chekugara mushure menguva pfupi. Ongororo yekutadza yakanongedza kukorokoza padanho remicroscopic. Mhinduro, iyo yatakagadzira mukubvunzana nechikwata chavo chekugadzira, yaive yekuchinjira ku316L ine yakaderera-kabhoni yemukati uye kutsanangura mhinduro yeannealing kurapwa mushure-kukandira kuti kukwidziridze kuramba kwecorrosion. Musiyano wehupenyu hurefu waive unoshamisa.
Unyanzvi hwavo mune alloys akakosha, senge nickel-based (funga Inconel 625) kana cobalt-based alloys (seStellite 6), yakakosha kune zvakanyanya masevhisi. Kune yakakwira-kudzvanywa boiler feedwater system uko cavitation erosion inouraya, isu takafukidza chigaro chechigaro che carbon steel ring neStellite tichishandisa chaiyo deposition process. Izvi zvakatipa kusimba kwesimbi ine nzvimbo yakaomesesa zvisingaite, isingakukurwe nevhu. Idzi nzira dzakasanganiswa dzinogadzirisa matambudziko epasirese.
Kugadzira Nuances: Kukanda uye Machining Interplay
Rwendo kubva pakukandwa kusvika pakupera cheki mhete yevharuvhu inokosha. Iyo iri padyo-net-shape kukanda kubva kune yakavimbika shell mold kana investimendi yekukandira maitiro, senge iyo QSY inyanzvi mazviri, inoderedza machining mvumo. Iyi ndiyo kiyi yezvinhu zvakaita sesimbi isina tsvina kana yakakwira-alloy, kwaunoda kuchengetedza zvivakwa uye kuderedza marara. Kubvisa hafu yeinji yemasheya kubva kune yakaoma alloy haisi kungodhura munguva yemuchina; zvinogona kukonzera stress.
Kutevedzana kwemuchina kunokosha. Iwe haugone kungozviseka wotarisana nazvo. Zvinhu zvinokwidziridzwa — ingave homwe inotsikirira kana kuti tambo yekuchengeta groove — inofanira kutanga yagadzirwa, kugadzira dhamu rako. Ipapo, uye ipapo chete, iwe unopedza iyo yakakosha yekuisa chisimbiso kumeso. Ndakaona zvindori uko kurongeka uku kwakadzoserwa kumashure, zvichitungamira kune yakanaka yekuisa chisimbiso nzvimbo yaive yakanyatso kuenderana pasina, ichikonzera kusarongeka mumuviri wevharuvhu.
CNC machining consistency haina kutaurirana. Kune batch maodha, kugona kwechitoro kubata kushivirira mumazana ezvimedu ndiko kunopatsanura chinhu chinoshanda kubva kune chinonetsa. Iko concentricity pakati peOD, chiso chekugara, uye chero maficha ekuchengetedza anowanzo furatirwa pamadhirowa asi akakosha kune kunyangwe kudzvanya uye nekusimbisa hupenyu. Mudiwa akanaka haangokumbira kudhirowa; ivo vachabvunza nezve dhizaini yevharuvhu, iyo dhisiki mhando, uye kushanda nesimba kuti vape zano pane izvi zvisingataurwi tolerances.
Real-World Application uye Kukundikana Ongororo
Rega nditsanangure musoro chaiwo. Chigadzirwa chemagetsi chaive chiri kuramba chichidonha mumvura yaro inotonhorera yekudzorera mavharuvhu. Mavharuvhu akagadziridzwa nemadhisiki matsva, asi epakutanga tarisa mhete dzevharuvhu vakangobatwa zvishoma. Kubuda kwacho kwakaramba kuripo. Pakuongororwa, chiso chechigaro chemhete chakaratidza zvishoma, sedhishi rakapfeka patani, pamwe 0.1mm kudzika pakati. Zvakanga zvisingaonekwe nemaziso asi zvakakwana kutyora chisimbiso. Chikonzero chikuru? Mhete dzepakutanga hadzina kumboomeswa, uye makore ekukanganisa kwedhisiki akange akonzera deformation yepurasitiki. Lapping yakangokwenenzvera chimiro chakaremara. Kugadzirisa kwakakodzera kwaive kutsiva zvindori neayo akaomeswa. Chidzidzo: gara uchiongorora ring kuti kupfava uye chimiro chepamusoro, kwete makwara epamusoro chete.
Mune imwe nyaya, kune marine ballast system, zvindori zvakatsanangurwa mu duplex simbi isina tsvina yekudzivirira ngura. Ivo vakatadza nguva isati yakwana nekuda kwegalling-iyo disc yaizoita micro-weld kune mhete pasi pekumanikidzwa. Nyaya yaive yekuti zvese disc nemhete zvaive zvekuoma kwakafanana uye alloy. Kugadzirisa kwaiva kutsanangura zvakasiyana, zvinopindirana zve disc (bronze alloy) kudzivirira kupfeka kwekunamatira, nekuchengeta duplex mhete yekudzivirira kwemuviri wayo. Kubatanidza zvinhu kwakakosha sechinhu pachacho.
Idzi hadzisi nyaya dzedzidziso. Ndidzo mhando dzezvinetso zvinotungamira kukudzikinura mafoni na2 am Iyo spec sheet kazhinji haifukidze zviitiko izvi, ndosaka ruzivo kubva kune veterans vekushandisa uye nyanzvi dzekugadzira dzakaona kukundikana uku - sechikwata chinobata maodha akaomarara panzvimbo senge. tsngtaocnc.com-inokosha. Havasi vanongotora hurongwa; ivo vanogadzirisa matambudziko vanonzwisisa kuti chikamu chinofanira kurarama muhurongwa, kwete kungosangana neprint.
Fungidziro Yeramangwana Nemifungo Yokupedzisira
Kutarisa mberi, kubatanidzwa kwezvindori zvisiri zvesimbi kana zvakaputirwa zviri kukura. PTFE-yakavharidzirwa kana ceramic-yakavharwa mhete dze Ultra-yakachena kana zvakanyanya abrasive masevhisi ari kuwanda kuwanda. Dambudziko rinoshanduka kubva kune yakawanda zvinhu zvivakwa kuenda kune adhesion kutendeseka uye kupisa kwekuwedzera kuenderana pakati pekupfeka uye simbi substrate. Iyo yekukanda uye machining base inofanira kunge isina kukanganisa kuti machira aya aenderere zvakanaka.
Uyezve, kusimuka kwekugadzira kwekuwedzera kunogona kupa mhinduro dzemhete dzakadhindwa dzakaomesesa emukati kutonhora mavharuvhu, asi parizvino, kukanda kwechinyakare uye CNC machining zvinopa musanganiswa wakanakisa wekutendeseka kwechimiro, mutengo-kubudirira, uye vhoriyamu kugadzirwa kweakawanda maindasitiri ekushandisa.
Saka, kana iwe uchizotevera kutsanangura kana kutsvaga a cheki mhete yevharuvhu, fambisa kupfuura nhamba yechikamu. Funga nezve yakazara basa kutenderera: iyo mvura, tembiricha inoshanduka, iyo inomanikidza spikes, kutenderera frequency. Wobva wabatana nemugadziri ane hudzamu hunoratidza mumibvunzo yavo, kwete kabhuku kavo chete. Chinangwa ndechekuti mhete iyoyo yakanganwe-kuita zvakavimbika zvekuti haizombove chikonzero chehurongwa hwebasa. Ndiwo mucherechedzo wechikamu chakanzwisiswa, kwete kungoitwa.
