Vanhu vazhinji pavanonzwa 'pombi yesimbi isina tsvina', vanofananidzira inopenya, isingaparare. Ndiyo yekutanga kusanzwisisa. Chokwadi ndechekuti, giredhi rinonyanya kukosha kupfuura iyo label. 304 inogona kunge yakanaka kune yekufambisa mvura application, asi isa mune yakapfava kemikari maitiro kana, zvakatonyanya, nzvimbo ine saline, uye uchaona kukundikana nekukurumidza kupfuura zvaungafunga. Ndakaona mapurojekiti akawandisa ekuti 'stainless' sekubata-zvese, kungobata nekuora nguva isati yakwana uye kutsiva kunodhura. Hazvisi zvezvinhu chete; zviri pamusoro pezvinhu zvakafanira zvebasa racho, uye kuti rinogadzirwa sei.
The Casting Foundation: Iko Kuvimbika Kunogadzirwa
Apa ndipo panotangira nyaya chaiyo. Kusimba kwepombi hakusi kungogadzirwa chete; zvakakandwa. Imba, mhepo, volute-izvi zvakakosha zvinotanga hupenyu hwazvo muforoma. Kwemakore makumi matatu mundima iyi, ndakadzidza kuti iyo yekutanga ndiyo gamba risingafadzirwe. Chikamu chisina kunaka chakakandwa, kunyangwe mu316L, chichava nemainclusions, nzvimbo dzisina simba, kana micro-porosity inova nzvimbo dzekukundikana pasi pekumanikidzwa kana kurwiswa kunoparadza. Iwe haugone kuisa mhando yemuchina kuita yekukanda kwakashata.
Ichi ndicho chikonzero chekutsvaga uye pombi yesimbi isina tsvina chikamu chekugadzira cheni yakakosha. Ndakashanda nevashambadziri vanocheka makona pane yekunyunguduka kana post-cast kupisa kupisa, uye mhedzisiro inogara yakafanana: kusawirirana kuita uye hupenyu husingatarisike. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nekutarisa kwavo kwenguva refu shell mold casting uye Investment casting, anonzwisisa izvi. Nguva yavo yemakore makumi matatu haisi nhamba chete; inotaura kune yakanatswa kutonga pamusoro pesimbi uye mold-kugadzira iyo inoshandura zvakananga kuhutano hwemaitiro muchikamu chepombi yekupedzisira. Kuumbwa kweShell, semuenzaniso, kunopa kupera kuri nani kwepamusoro uye kurongeka kwechimiro pane kukanda jecha rechinyakare, zvinoreva kushomeka kwekushushikana uye kuyerera kuri nani mukati mekamuri yepombi.
Ndinoyeuka chimwe chirongwa patakanga tichigadzirisa pombi dzemvura inotonhodza mumhenderekedzo yegungwa. Dzimba dzekutanga dzesimbi dzakaumbwa dzaiputsika. Takachinjira kuna a simbi isina tsvina pombi, asi bhechi rekutanga rekukandwa kubva kumutengesi mutsva rakatadza kuona-matanho emadeoxidizer asina kunaka. Taifanira kubvisa chikamu chose. Chakanga chiri chidzidzo mukutsvaga kwete chete chitupa chezvinyorwa, asi iyo yekutanga yemhando yeprotocol. Iko kuwirirana kubva kune yakarungwa foundry hakugone kutaurirana.
Machining Precision: Iyo Yakakodzera Inorayira Kuita
Kunyangwe kuumbwa kwakakwana kunongova kuvezwa kwakashata. Iko kurongeka kunobva mukugadzira. Kushivirira paruoko rwepombi shaft, kupera kwepamusoro kwekamuri yechisimbiso, kusimba kwechibatiso - izvi ndizvo zvinoparadzanisa bhiza rebasa rakanyarara, rinoshanda kubva kune rinodedera, rinodonha. CNC machining ndiyo chiyero chechikonzero, asi kwete ese CNC zvitoro akaenzana pombi zvikamu.
Dambudziko ne simbi isina tsvina ndiwo maitiro ayo ekuomesa basa. Kana maparamita ako emuchina akadzimwa - chiyero chekudyisa, kukurumidza kucheka, kutonhora - unogona kunyatso kudzikamisa zvinhu zvemukati, uchigadzira madiki mafractures kana ganda rakaomarara rinowanzo kuputika. Ndakaita ma impellers adzoka kubva kumachining aitaridzika akakwana asi akatadza muyedzo yechiyero nekuti nzira yekushandisa yakakonzera kusara kunetseka. Chinhu chakajeka chinongoratidzira mukushanda.
Apa ndipo pane zvakabatanidzwa kugona. Shamwari inobata zvese zviri zviviri kukanda uye CNC machining mumba, senge QSY inotaura mukushanda kwavo, ine mukana wakakura. Iwo machinist anonzwisisa chimiro chezviyo uye hunhu hwemakanda avari kushanda nawo. Ivo vanogona kugadzirisa maitiro zvichibva pane chaiyo yekupisa yakawanda simbi isina tsvina kana special alloy. Kuenderera mberi uku kunoderedza zvinoshanduka uye, mune yangu ruzivo, zvinotungamira kune yakavimbika chikamu chekupedzisira che pombi yesimbi isina tsvina assembler.
Material Nuances: Haina Kungoita Stainless
Ngatitorei zvakananga. 304. Sarudzo ndeye zvese. 316L, ine molybdenum zvirimo, ndiyo inosarudzika kune akawanda emakemikari mabasa, asi kushaya simba kwayo makloridi. Ndiko uko Duplex simbi, neyakasanganiswa austenitic-ferritic chimiro, inopinda ine zvirinani kusagadzikana ngura kuputsa kuramba.
Ndakashanda pane biodiesel chirimwa chirongwa uko nzira yekuyerera yaive nemafuta acids uye methanol. Isu takatanga tafungidzira 316L. Yakamira kwegore, tichibva tatanga kuona kukombama kwakatenderedza zviso zvegasket. Zvakazoitika, kutsvaga ma chlorides kubva pakusvibiswa kwe feedstock ndiyo yaive mhosva. Taifanira kusimudzira zvikamu zvakanyorova kuti a super duplex simbi isina tsvina. Yakanga iri retrofit inodhura iyo ingadai yakadziviswa nekuongorora kwakanyanya kwekutanga kwemvura uye kusarudzwa kwezvinhu. Iyo pombi furemu nechigadziko chaigona kugara se304, asi chikamu chese chakanyorova chaida kukwidziridzwa.
Ichi ndicho chikonzero mararamiro emutengesi ari kutaura. Kana kambani inonyora ruzivo ne special alloys kufanana necobalt-based kana nickel-based alloys, zvinoratidza kuti vakashongedzerwa mabasa akaomarara-kupisa kwepamusoro, kusvibisa zvakanyanya, kana abrasive slurry application. Idzi hadzisi dzepasherufu mhinduro; ivo vanoda ruzivo rwehunyanzvi mune zvese kukanda uye kugadzira, izvo zvinodya zvakananga mukuvaka yakasimba zvechokwadi pombi yesimbi isina tsvina nokuda kwebasa rakanyanyisa.
The Assembly & Real-World Ghosts
Iwe unogona kuve wakanyatsokanda uye akagadzirwa zvinhu, uye uchiri kuunganidza yakaipa pombi. Kukwana pakati peshaft nesleeve, kurongeka kwezviso zvema mechanical seal, kutenderedzwa kwakakodzera kwemafasteners—apa ndipo panowanzotangira kukanganisa kwemunda. Ndakaona yakanaka yekudyara-yakakanda impeller yakaparara nekuti vashandi vegungano vakashandisa nyundo kuigadzika pashaft, vachivhundutsa mabheya kubva pazuva rekutanga.
Imwe mweya ndeye cavitation. Vanhu vanopomera pombi, asi kazhinji inyaya yekugadzira system. Zvisinei, zvinhu uye kuvakwa kwepombi zvinogona kukanganisa kukanganisa. Iyo cavitating pombi inodya kuburikidza nechero chinhu, asi yakaderera-giredhi simbi isina tsvina kana kuti ane zvikanganiso zvekukanda achapwanya uye agova negomba nekukurumidza. Kukandira kwepamusoro-soro negiredhi rakakodzera kunogona kukutengera nguva yekuongorora uye kugadzirisa dambudziko rehurongwa risati ratadza zvachose.
Ndiwo matambudziko aya epakati-ayo ari pakati pechikamu uye yekumisikidzwa kwekupedzisira-anodzora hupenyu hwepombi. Hunhu hwehwaro hwezvikamu kubva kune foundry uye muchina shopu inoisa sirin'i kune izvo zvinogoneka mumunda. Kana izvo zvikamu zvine mutsindo, uri kurwisa nyaya dzehurongwa, kwete kukanganisa kwemidziyo.
Kutarisa Kumashure Kuti Uende Mberi
Saka, chii chekutora? Kutsanangura a pombi yesimbi isina tsvina haisi cheki bhokisi. Iketani yezvisarudzo: iyo chaiyo alloy yemvura uye nharaunda, nzira yekukanda inokwanisa kuburitsa ruzha, homogeneous chimiro, chaiyo machining inoremekedza zvivakwa zvezvinhu, uye pakupedzisira, inokwanisa kusangana uye system yekubatanidza.
Kana ndichiongorora vatengesi, ini zvino ndinotarisa seri kwebhurocha repombi kune chikamu chavo chekugadzira pedigree. Nhoroondo yakadai Nhoroondo ye QSY-Makore makumi matatu ekukandira nekugadzira kubva kune yakakandwa simbi kuenda special alloys-inoratidza hudzamu hwesimbi uye nzira yeruzivo iyo inosefa kusvika mukuvimbika kwechigadzirwa chekupedzisira. Havasi chete mutengesi; ndiwo tsime rezvivakwa zvakakosha zvekuvaka.
Nguva inotevera paunopinda mupurojekiti yepombi, chera mukati mechikamu kwakabva. Bvunza nezve nzira yekukanda, kurapwa kwekupisa, iyo machining sosi. Ndiko uko hondo chaiyo yekurarama kwenguva yakareba inohwinwa kana kurasikirwa, nguva refu pombi isati yamboona kudonha kwayo kwekutanga kwemvura. Nzvimbo inopenya inongova magumo enyaya refu, ine udzame.
