Iyo impeller inoreva dhisiki revhiri rine mashizha anofambisa. Mupombi yecentrifugal, impeller inoreva mutumbi unotenderera une mablades anoendesa simba kumvura.
Mablades epombi ye centrifugal impellers anowanzo dzokera kumashure akachinjika. Kune marudzi maviri emashizha: cylindrical uye twisted. Kushandiswa kwemashizha akakomberedzwa kunogona kuderedza mutoro wemashizha, kunatsiridza kushandiswa kwepombi ye centrifugal, uye kuvandudza kukwanisa kwe-anti-cavitation, asi kugadzirwa kwakaoma uye mari yakakwirira.
Iyo centrifugal pombi yekunatsa uye indasitiri yemakemikari inoda kuti chinodzimisa chikandwe kana kuti chakazara welded integral impeller. Iko kugadzirwa kwewelded impellers kunonyanya kushandiswa kumakemikari akakosha centrifugal pombi akagadzirwa nesimbi zvinhu zvine hurombo hwekukanda zvivakwa (senge simbi uye alloys ayo). Iko kurongeka kwejometri uye kupedzisa kwepamusoro kweiyo welded impeller zviri nani pane iyo yekukanda impeller, iyo inobatsira kuvandudza kushanda kwepombi ye centrifugal.
Zvinoenderana nemaitiro ekugadzirisa, iyo impeller inogona kukamurwa kuita riveted mhando, welded mhando uye yakakosha mhando. Iyo yakabatanidzwa yakaumbwa impeller inonyanya kureva iyo chaiyo yekukanda maitiro uye mamwe akakosha maitiro. Theprecision casting processinochengetedza zvose maawa-awa uye zvinhu, asi nekuda kwechimiro chakaoma che impeller uye yakakwirira yekugadzirisa zvinodiwa, zvakaoma kuve nechokwadi kuti makanda haana pores uye tsvina.
RMC Foundryinogona kugadzira mhando dzakasiyana dzemapeller uchishandisa iyo chaiyo yekukanda maitiro (investment casting) zvakareCNC chaiyo machining. Tinokwanisa kugadzira mapopotera akanyanya-chaiyo, asingadziviriri kubva kune austenitic stainless simbi, duplex stainless simbi, kunaya kwakaoma simbi isina tsvina, uye nickel-based alloys.
Parizvino, mhando dzakakosha dze centrifugal pombi impellers dzinoyerera chiteshi mhando (imwe yekuyerera chiteshi, kaviri kuyerera chiteshi), vane mhando (yakavharwa mhando, yakavhurika mhando), spiral centrifugal mhando uye swirl mhando.
1. Channel Type Impeller
Iyo inoyerera chiteshi impeller inzira yakakomberedzwa inoyerera ichibva painopinza ichienda kunobuda. Rudzi urwu rwemaperembudzi rwakakodzera kufambisa zvinwiwa zvine zvidimbu zvihombe zvetsvina kana shinda refu. Nekuti iyi mhando ye impeller ine yakanakisa anti-kuvhara zvivakwa. Asi chakashata chake ndechekuti iyo anti-cavitation performance haina kusimba pane mamwe mafomu.
2. Vane Impeller
Masemi-akavhurika uye akavhurika impellers mune vane impeller ari nyore kukanda, uye nyore kuchengetedza uye kuchenesa tsvina yakavharika mukufambisa nzira. Nekudaro, chakashata chayo ndechekuti gaka riri pakati pemadziro emukati memvura yakamanikidzwa uye blade iri pasi peabrasion yezvikamu zvakasimba zvinowedzera panguva yekufambisa, izvo zvinoderedza kushanda kwepombi, uye kugadzikana kwekuyerera kwemvura. mugero rekuyerera rinoparadzwa nekuda kwekuwedzera kwegap. , ita kuti pombi izununguke, rudzi urwu rwemhepo haisi nyore kutakura svikiro rine zvidimbu zvakakura uye fiber refu. Iyo yakavharwa impeller ine yakakwirira yekushanda inoshanda uye inogona kumhanya zvakanaka kwenguva yakareba. Iyo axial thrust yepombi idiki, asi iyo yakavharwa impeller iri nyore kukuvadzwa, uye hazvisi nyore kutakura tsvina midhiya ine zvidimbu zvakakura kana refu fiber.
3. Spiral Centrifugal Impeller
Spiral centrifugal impellers ane mablades akamonyoroka anowedzera axially kubva pachiteshi chekusveta pane tapered hub body. Mvura inotakurwa haigoni kurova chero chikamu chepombi kana ichiyerera nepakati pemashizha, saka hapana kukuvadzwa kwepombi, uye panguva imwe chete, haisi kuparadza kune mvura inotakurwa. Nekuda kwekufambiswa kwe screw, iyo yakamiswa zvidimbu zvine simba rekupfuura, saka rudzi urwu rwunogamuchirwa. Mapombi emapombi akakodzera kupomba midhiya ine zvidimbu zvakakura uye refu fibers.
4. Swirl Impeller
Iyo inotenderedza impeller ndeyese kana chikamu cheiyo impeller inodzoserwa kune inoyerera chiteshi chemukamuri yakamanikidzwa yemvura, iyo ine yakanaka anti-kuvhara kuita. Izvo zvimedu zvinoyerera mukamuri yekumanikidza mvura pasi pekukurudzira kwevortex inogadzirwa nekutenderera kweiyo impeller, uye kufamba kwezvimedu zvakamiswa hazviburitse simba, uye kuchinjanisa simba nemvura iri mugero rekuyerera. Munguva yekuyerera, zvimedu zvakasimirirwa kana mafibhi akareba hazvibatanidzi mashizha akasakara, mashizha anowedzera kupfeka, uye gomba harina kuwedzera nekuda kwebrasion. Inokodzera kupomba midhiya ine zvidimbu zvakakura uye mafibhi akareba.
Mavane impellers anoshandiswa mumapombi ecentrifugal anogona kukamurwa kuita mana: (a) mhando yakavharwa; (b) pamberi hafu-yakazaruka mhando; (c) kumashure hafu-yakavhurika mhando; (d) vhura mhando
1. Yakavharwa impeller
Iyo yakavharwa impeller ine blades uye mberi uye kumashure kwekuvhara mahwendefa. Iyo yakavharwa impeller ine hunyanzvi hwepamusoro uye yakaoma kugadzira, uye inonyanya kushandiswa mumapombi ecentrifugal. Yakakodzera kutakura zvinwiwa zvakachena zvine viscosity yakaderera uye isina zvimedu, zvakaita semvura yakachena nemhinduro.
2. Semi-yakavhurika impeller
Iyo semi-yakavhurika impeller kazhinji ine zvimiro zviviri: imwe ndiyo yekumberi semi-yakavhurika mhando, iyo inoumbwa yekumashure yekuvhara ndiro uye mablades. Iyo impeller inoshanda yeichi chimiro yakaderera, uye mhete yekuisa chisimbiso ine inogadziriswa clearance inodiwa kuti ivandudze kushanda; imwe yacho iplate yekumashure nebadza. Iyo semi-yakavhurika mhando ine pamberi pekuvhara ndiro uye blade. Sezvo mhete imwe chete yekuisa chisimbiso seyakavharwa impeller ichigona kuiswa, iko kunyatsoshanda kwakafanana neiyo yakavharwa impeller, uye blade zvakare ine (kumashure blade kana yekubatsira impeller) chisimbiso mukuwedzera pakufambisa mvura. effect. Iyo semi-yakavhurika impeller inokodzera kufambisa zvinwiwa zvine zvakaturikwa zvimedu zvakaita sezvimedu zvakaonda uye fiber. Iyo semi-yakavhurika impeller haina kunetsa kugadzira, yakaderera mumutengo, uye ine yakasimba kuchinjika.
3. Vhura impeller
Iyo impeller yakavhurika ine mablades chete uye blade inosimbisa mbabvu, uye hapana impeller ine pamberi uye kumashure kwekuvhara mahwendefa. Iyo impeller ine yakaderera kushanda uye kushoma maapplication, uye inonyanya kushandiswa kutakura zvinwiwa zvine yakakwira viscosity uye slurry zvinwiwa.
