Kana pombi ichibuda kubva pa 6" kuenda pa 4" nejoini, izvi zvichakanganisa pombi here? Mumapurojekiti chaiwo, tinowanzo kunzwa zvikumbiro zvakafanana. Kuderedza pombi inobuda mvura kunogona kuwedzera kumanikidzwa kwemvura zvishoma, asi nekuda kwekuwedzera kwehuwandu hwemvura inobuda mupombi, zvichawedzera kurasikirwa kwe hydraulic.
Ngatitaurei nezvemhedzisiro yekuderedza pombi inobuda papombi.
Kukanganisa kwekuderedza pombi inobuda
1. Kuchinja kwema hydraulic parameters: kuwedzera kwekumanikidzwa, kuderera kwekuyerera, uye njodzi yekudedera
Mhedzisiro yekuvhuvhuta:Kuderedza nzira yekubuda kwemvura mupombi kwakafanana nekuvhara vharuvhu yekubuda yepombi. Kuderedza dhayamita yekubuda kwakaenzana nekuwedzera coefficient yekuramba kwenzvimbo. Zvichitevera fomura yeDarcy-Weisbach, kumanikidzwa kwesystem kuchasvetuka zvisina kurongeka (data rekuyedza rinoratidza kuti kudzikiswa kwedhayamita ne10% kunogona kutungamira kukuwedzera kwe15-20% mukumanikidzwa), nepo mwero wekuyerera uchiratidza mutemo wekudzikiswa kweQ∝A·v.
Kunyangwe simba remubato richidzikira neinenge 8-12% nekudzikira kwekuyerera, simba rekudengenyeka rinokonzerwa nekuputika kwesimba rinogona kuwedzera ne20-30%, kunyanya pedyo nekumhanya kwakakosha, izvo zviri nyore kukonzera kurira kwechimiro.
2. Hukama huripo pakati pemusoro nekumanikidzwa: Musoro wedzidziso unoramba usina kuchinja, kumanikidzwa chaiko kunochinja-chinja
Musoro weoretical unoramba usina kuchinja:Musoro wepfungwa weimpeller unotsanangurwa ne geometric parameters uye hauna hukama hwakananga nedhayamita yekubuda kwemvura.
Kuyerera kwepombi kunowedzera kumanikidzwa kwekubuda kwepombi: Kana nzvimbo yekushanda yesystem ichifamba neHQ curve uye mamiriro ekunze achichinja (sekuchinja-chinja kwekudzivirira kwenetwork yepombi), kushanduka kwesimba remhepo kunowedzera ne30-50%, uye kufanotaura kwesimba kunodiwa kuburikidza ne pressure-flow characteristic curve.
3. Kuvimbika kwemidziyo:mazano ekutarisa mhedzisiro yehupenyu uye kukanganiswa kwahwo
Kana mamiriro ekushanda asina kunaka zvakanyanya, zvichakanganisa hupenyu hwepombi. Kuongororwa kwekuzunguzika kunogona kuitwa, uye kugadzirisa modal analysis kunogona kuitwa kana zvichidikanwa.
4. Muganho wekuchengetedza:zvirevo zvekugadzirisa uye mutoro wemota
Maitiro ekugadzirisa:Dhayamita yekubuda kwemvura haifanirwe kunge iri pasi pe75% yehukuru hwedhizaini yekutanga. Kudzvanya zvakanyanya kuchaita kuti motor service factor (SF) ipfuure mwero wekuchengetedza.
Kana muganho wekuchengetedza ukadarika, kuyerera kwemvura kusina kunaka kuchaunza kumanikidzwa kupombi yemvura, kuwedzera mutoro wemota, uye mota ichazara. Kana zvichidikanwa, simba remhepo rinofanira kufanotaurwa kuburikidza neCFD simulation, uye flow coefficient inofanira kuenzaniswa ne ultrasonic flowmeter kuona kuti mwero wemota unodzorwa uri pasi pe 85% yemutengo wakayerwa.
5. Kudzora kuyerera kwemvura:hukama hwakananga pakati pedhayamita nekuyerera
Zvinokanganisa zvakananga kufamba kwepombi yemvura, kureva kuti, kana pombi yemvura yakakura, kufamba kwepombi yemvura kunowedzera, uye zvinopesana. (Kufamba kwemvura kwakabatana zvakanaka nenzvimbo inoyambuka pombi yemvura. Kuedza kunoratidza kuti kudzikira kwe10% mudhayamita kunoenderana nekudzikira kwe17-19% mukuyerera)
