Kana pombi yecentrifugal yatangwa, hapana mvura mupombi yekubuda nayo yepombi, saka hapana kumira kwepombi uye kusimudza kureba. Mushure mekunge pombi ye centrifugal yatangwa, musoro wepombi ye centrifugal wakadzikira uye kuyerera kwakakura kwazvo. Panguva ino, kubuda kwepombi yepombi (shaft power) yakakura kwazvo (maererano nepombi yekuita curve), iyo iri nyore kuisa, iyo inokuvadza pombi yepombi uye dunhu. Naizvozvo, vhara vharafu yekubuda kana uchitanga, Kuti pombi ishande zvakajairika. Kuvhara chivharo chekubuda kwakaenzana nekugadzira pombi kuramba kumanikidza. Mushure mekunge pombi ichishanda zvakajairika, zvishoma nezvishoma tanga vharuvhu kuita kuti pombi ishande zvakajairika nhanho nhanho pamwe nemutemo wekuita kwayo curve.
Mapoinzi maviri anofanirwa kuvimbiswa usati watanga pombi yecentrifugal:
1. Zadza chivharo chepombi nemvura kuti uite vacuum;
2. Ivhavha papombi yekubuda kwemvura inofanira kuvharwa kuitira kuti pombi yemvura irege kuumba kuyerera, iyo inogona kuderedza motokari inotanga ikozvino uye kufambisa kutanga kwakanaka kwepombi yemvura. Nekutanga kwakanaka kwepombi yemvura, valve yegedhi inofanira kuvhurwa zvishoma nezvishoma uye nenguva.
Centrifugal pombi inovimba nekusvetwa kwevacuum inoumbwa neiyo centrifugal simba reimpeller kusimudza mvura. Nokudaro, paunotanga pombi ye centrifugal, unofanira kutanga uvhara valve yekubuda uye uzadze mvura. Kana huwandu hwemvura huchipfuura nzvimbo yeimpeller, pombi yecentrifugal inogona kutangwa chete mushure mekunge mhepo iri mupombi yecentrifugal yabudiswa. Mushure mekutanga, vacuum inoumbwa yakatenderedza iyo impeller yekuyamwa mvura, iyo inogona kuvhurwa yega uye kusimudza mvura. Nokudaro, valve yekubuda inofanira kuvharwa kutanga.
Nezve centrifugal pombi:
Centrifugal pombi impombi ine vane, inotsamira pane inotenderera inotenderera. Mukuita kutenderera, nekuda kwekudyidzana pakati peblade uye mvura, blade inoendesa magetsi emagetsi kumvura, kuitira kuti kudzvanywa kwemvura kuwedzere kuzadzisa chinangwa chekufambisa mvura. Iyo pombi yecentrifugal ine zvinotevera maitiro:
1. Pane muganhu wepamusoro wemusoro unogadzirwa nepombi ye centrifugal pane imwe nguva. Iyo yekuyerera poindi yekuyerera uye shaft simba zvinoenderana nemamiriro eiyo mudziyo sisitimu yakabatana nepombi (level musiyano, kudzvanywa musiyano uye kurasikirwa kwepombi). Musoro unosiyana nekuyerera.
2. Kushanda kwakagadzikana, kuenderera mberi kwekufambisa, uye pasina pulsation yekuyerera uye kudzvinyirira.
3. Kazhinji, haina self-priming capacity. Izvo zvinodiwa kuzadza pombi nemvura kana vacuum pombi usati watanga kushanda.
4. Pombi yecentrifugal inotangwa kana vharuvhu yepombi yekuburitsa yakavharwa, uye pombi yevortex neaxial flow pump zvinotangwa kana vharuvhu yanyatsovhurwa kuderedza simba rekutanga.
Pombi isati yatangwa, ganda repombi rinozadzwa nemvura inotakurwa; Mushure mekutanga, iyo impeller inotenderera nekumhanya kwepamusoro inofambiswa neshaft, uye mvura iri pakati pemashizha inofanirawo kutenderera nayo. Pasi pechiito che centrifugal simba, mvura inokandwa kubva pakati peimpeller kusvika kumucheto wekunze uye inowana simba, ichisiya kunze kwekunze kweimpeller nekukurumidza uye kupinda muimba yepombi yevolute.
Mune volute, iyo mvura inodzikira nekuda kwekuwedzera zvishoma nezvishoma kweyekuyerera chiteshi, inoshandura chikamu chekinetic simba kuita static pressure simba, uye pakupedzisira inoyerera ichipinda mupombi yekuburitsa pane yakanyanya kumanikidza uye inotumirwa kunzvimbo kwainodiwa. Kana iyo mvura inoyerera ichibva pakati peiyo impeller kuenda kumucheto wekunze, imwe vacuum inoumbwa pakati peiyo impeller. Sezvo kudzvanywa kuri pamusoro peyero yemvura yetangi yekuchengetera kwakakura kupfuura kudzvanywa kwepakupinza kwepombi, iyo mvura inoramba ichitsikirirwa mune impeller. Zvinogona kuonekwa kuti chero bedzi iyo impeller ichitenderera ichienderera, mvura inoyamwa mukati uye ichibudiswa nguva dzose.
Kutanga kwemamwe mapombi ecentrifugal:
Izvo zvataurwa pamusoro apa ndeye centrifugal pombi. Kune mamwe marudzi emapombi, mamiriro acho ndeaya:
Huru kuyerera kutanga maitiro e01 axial kuyerera pombi
Kana iyo yakazara yakavhurika vharuvhu ichitanga iyo axial kuyerera pombi, iyo shaft simba ndiyo yakakura pasi pe zero kuyerera mamiriro, ayo ari 140% ~ 200% yeyakayerwa shaft simba, uye simba ndiro shoma pakuyerera kwakanyanya. Naizvozvo, kuti uderedze kutanga ikozvino, hunhu hwekutanga hweshaft simba hunofanirwa kuve kuyerera kukuru kutanga (kureva vharafu yakazara yakavhurika kutanga).
02 kutanga maitiro emusanganiswa wekuyerera pombi
Kana pombi yekuyerera yakasanganiswa yatangwa nevharuvhu yakazara yakavhurika, iyo shaft simba iri pakati pemapombi maviri ari pamusoro pasi pe zero kuyerera mamiriro, iri 100% ~ 130% yesimba rakayerwa. Nokudaro, maitiro ekutanga epombi yakasanganiswa inoyerera inofanirawo kuva pakati pemapombi maviri ari pamusoro, uye zviri nani kutanga nevhavha yakazara yakazaruka.
03 maitiro ekutanga epombi yevortex
Yakazara yakavhurika vharafu kutanga vortex pombi ine yakanyanya shaft simba pasi pe zero kuyerera mamiriro, iri 130% ~ 190% yeyakayerwa shaft simba. Naizvozvo, zvakafanana neaxial kuyerera pombi, hunhu hwekutanga hwepombi yevortex hunofanira kunge hwakakura kuyerera kwekutanga (kureva kuvhura yakazara valve kutanga).
