Invharafuengineering, iyo Cv kukosha (Kuyerera Coefficient) yekutongavharafuinoreva kuyerera kwevhoriyamu kana kuwanda kwekuyerera kwepakati pepombi kuburikidza nevharuvhu panguva yeyuniti uye pasi pemamiriro ekuyedzwa apo pombi inochengetwa pakudzvanywa nguva dzose. Ndiko kuti, kuyerera kwevhavha.
Iyo yakakwirira yeyekuyerera coefficient kukosha, iyo yakaderera yekumanikidzwa kurasikirwa sezvo mvura inoyerera kuburikidzavharafu.
Iko Cv kukosha kwevhavha inofanira kugadziriswa nekuedza uye kuverenga.
The CVvaluendiyo yakakosha tekinoroji parameter inoyera kuyerera kwevharuvhu pasi pemamiriro chaiwo. Kukosha kweCV hakungoratidzi kushanda kwevhavha pachayo, asi inobatanidzawo zvakananga nekugadzirwa uye kushanda kwemaitiro ekugadzirisa mvura.
Tsanangudzo inowanzoenderana neanotevera chiyero mamiriro: thevharafuyakavhurika zvakazara, mutsauko wekumanikidza i1 lb/in² (kana 7KPa) kumagumo, uye mvura inosvika 60 ° F (15.6 ° C) yemvura yakachena, panguva iyo huwandu hwemvura (muUS magaloni) inopfuura nemuvharuvhu paminiti ndiyo yevhavha kukosha kweCv. Izvo zvinofanirwa kucherechedzwa kuti kuyerera kwekofi muChina kunowanzo kutsanangurwa mune metric system, ine chiratidzo Kv, uye hukama neCv kukosha ndeye Cv = 1.156Kv.
Maitiro ekuona caliber yevhavha neiyo Cv kukosha
1. Verenga kukosha kweCV yaunoda:
Zvinoenderana nezvinodiwa chaizvo zveiyo fluid control system, sekuyerera, kusiyanisa kudzvanywa, yepakati uye mamwe mamiriro, iyo inodiwa Cv kukosha inoverengerwa uchishandisa inoenderana formula kana software. Iyi nhanho inotarisa zvinhu zvakadai sechimiro chemuviri wemvura (semuenzaniso, viscosity, density), maitiro ekushanda (semuenzaniso, tembiricha, kumanikidza), uye nzvimbo yevharuvhu.
2. Sarudza dhayamita yevharuvhu yakarurama:
Zvinoenderana neyakaverengerwa inodiwa kukosha kweCv uye yakatarwa Cv kukosha kwevhavha, iyo yakakodzera dhayamita yevharuvhu inosarudzwa. Iyo yakarongerwa kukosha kweCv yevhavha yakasarudzwa inofanira kuenzana kana kuti yakakura zvishoma pane inodiwa Cv kukosha kuti ive nechokwadi chekuti valve inogona kusangana nekuyerera chaiko kudiwa. Panguva imwecheteyo, inofanirwawo kufunga zvimwe zvinhu zvakadai sezvinhu, chimiro, kuisa chisimbiso, uye maitiro ekushanda kwevhavha kuitira kuti kuve nechokwadi chokuti kushanda kwevhavha kunosangana nezvinodiwa zvehurongwa.
3. Verification uye Kugadzirisa:
Mushure mekutanga kusarudzwa kwevharafucaliber, iyo inodiwa yekuongorora uye kugadzirisa kunofanirwa kuitwa. Izvi zvinosanganisira kuona kuti kuyerera kwevharuvhu kunosangana nezvinodiwa nehurongwa kuburikidza nekuenzanisa masvomhu kana kuyedza-yepasirese. Kana kukanganisa kukuru kunowanikwa, zvingave zvakakosha kudzokorora kukosha kweCv kana kugadzirisa dhayamita yevhavha.
Summary
Muchivakwa chekugadzirisa mvura kwechivako, kana vheji yekudzora isingasviki neCV inodiwa, pombi yemvura inogona kutanga uye kumira kakawanda kana kumhanya pamutoro mukuru nguva dzose. Hakusi chete uku kutambisa simba remagetsi, asi nekuda kwekuchinja-chinja kwemhepo nguva zhinji, zvinogona kutungamira kune yakasununguka pombi yekubatanidza, inodonha, uye inogona kutokonzera kukuvadzwa kwepombi nekuda kwekuremerwa kwenguva refu.
Muchidimbu, kukosha kweCv yevhavha yekudzora chiratidzo chakakosha chekuyera kuyerera kwayo. Nekunyatsoverenga kukosha kweCv uye kusarudza iyo yakakodzera yevhavha caliber yakavakirwa pairi, kugadzikana uye kugona kweiyo fluid control system inogona kuve nechokwadi. Nokudaro, mukugadzirisa kusarudzwa kwevhavha, hurongwa hwekugadzirisa uye kushandiswa kwekushanda, kunyatsoteerera kunofanira kubhadharwa kune kuverenga uye kushandiswa kweCv kukosha.
