Zvinorevei kukosha kweCV? Ungasarudza sei vharuvhu yekudzora nemutengo weCv?

Invharuvhumainjiniya, kukosha kweCv (Flow Coefficient) yekudzoravharuvhuzvinoreva mwero wekuyerera kwehuwandu kana mwero wekuyerera kwehuwandu hwepombi inopinda nevharuvhu panguva imwe neimwe uye mumamiriro ekuyedzwa apo pombi inochengetwa iri padzvinyiriro inogara iripo. Kureva, kugona kwekuyerera kwevharuvhu.

Kana flow coefficient yakakwira, pressure loss inoderera sezvo mvura ichiyerera ichipinda muvharuvhu.

Kukosha kweCv kwevharuvhu kunofanirwa kutsanangurwa nekuyedza uye kuverenga.

CVkukoshachinhu chakakosha chehunyanzvi chinoyera kugona kwevharuvhu yekudzora pasi pemamiriro ezvinhu chaiwo. Kukosha kweCV hakungoratidzi chete mashandiro evharuvhu pachayo, asiwo kune chekuita zvakananga nekugadzirwa uye kushanda zvakanaka kwesystem yekudzora mvura.

Tsanangudzo yacho inowanzo enderana nemamiriro ezvinhu anotevera:vharuvhuyakavhurika zvizere, musiyano wekumanikidzwa uri 1 lb/in² (kana 7KPa) kumagumo, uye mvura yacho iri 60°F (15.6°C) yemvura yakachena, ipapo huwandu hwemvura (mumagaloni ekuUS) inopfuura nepavharuvhu paminiti ndiyo Cv yevharuvhu. Zvinofanira kucherechedzwa kuti flow coefficient muChina inowanzotsanangurwa mumetric system, ine chiratidzo cheKv, uye hukama neCv value iCv=1.156Kv.

Maitiro ekuona caliber yevharuvhu neCv value

1. Verenga kukosha kweCV kwaunoda:

Zvichienderana nezvinodiwa chaizvo zvesystem yekudzora mvura, zvakaita sekuyerera, kumanikidzwa kwakasiyana, mamiriro epakati nezvimwe, kukosha kweCv kunodiwa kunoverengerwa uchishandisa fomura kana software inoenderana. Danho iri rinotora zvinhu zvakaita sehunhu hwemvura (semuenzaniso, viscosity, density), mamiriro ekushanda (semuenzaniso, tembiricha, kumanikidzwa), uye nzvimbo yevharuvhu.

2. Sarudza dhayamita yevharuvhu yakakodzera:

Zvichienderana neCv value inodiwa yakaverengerwa uye Cv value yakayerwa yevharuvhu, dhayamita yakakodzera yevharuvhu inosarudzwa. Cv value yakayerwa yevharuvhu yakasarudzwa inofanira kunge yakaenzana kana kuti yakakura zvishoma pane Cv value inodiwa kuti ive nechokwadi chekuti vharuvhu inogona kusangana nezvinodiwa chaizvo. Panguva imwe chete, zvakakoshawo kufunga nezvezvimwe zvinhu zvakaita sezvinhu, chimiro, mashandiro ekuvhara, uye mashandiro evharuvhu kuti ive nechokwadi chekuti mashandiro ese evharuvhu anosangana nezvinodiwa zvesystem.

3. Kusimbiswa uye Kugadziriswa:

Mushure mekusarudzwa kwekutanga kwevharuvhucaliber, kuongororwa nekugadziriswa kunodiwa kunofanira kuitwa. Izvi zvinosanganisira kuona kuti mashandiro evharuvhu anosangana nezvinodiwa zvesystem kuburikidza nekuverenga simulation kana kuyedza chaiko. Kana pakawanikwa musiyano mukuru, zvingangodiwa kuverengazve Cv value kana kugadzirisa dhayamita yevharuvhu.

Pfupiso

Munzvimbo yekuisa mvura muchivako, kana vharuvhu yekudzora isingasvike paCV inodiwa, pombi yemvura inogona kutanga nekumira kakawanda kana kushanda nesimba nguva dzese. Izvi hazvisi kungotambisa simba remagetsi chete, asi nekuda kwekuchinja-chinja kwesimba remagetsi, zvinogona kutungamira pakusangana kwemapaipi asina kusimba, kubuda kwemvura, uye zvinogona kutokonzera kukuvara kwepombi nekuda kwekuwanda kwenguva refu.

Muchidimbu, kukosha kweCv kwevharuvhu yekudzora chiratidzo chakakosha chekuyera kugona kwayo kuyerera. Nekuverenga kukosha kweCv nemazvo uye kuona caliber yakakodzera yevharuvhu zvichibva pairi, kugadzikana uye kushanda zvakanaka kwesystem yekudzora mvura kunogona kuve nechokwadi. Saka, mukusarudza mavharuvhu, dhizaini yesystem uye kugadzirisa mashandiro, kutarisisa kwakazara kunofanirwa kupihwa pakuverengwa nekushandiswa kweCv.
