1.Kuchinja mu hydraulic parameters: kuwedzera kudzvinyirira, kuderera kwekuyerera, uye kudengenyeka kwengozi
Throttling effect:Kuderedza kubuda kwemvura kwepombi chaizvoizvo kwakafanana nekuvhara vharafu yekubuda yepombi. Kuderedza dhayamita yekubuda kwakaenzana nekuwedzera nharaunda yekupikisa coefficient. Kutevera dhizaini yeDarcy-Weisbach, iyo system pressure ichasvetuka isingaiti (yekuongorora data inoratidza kuti kuderedzwa kwe10% mudhayamita kunogona kutungamirira ku 15-20% kuwedzera kwekumanikidzwa), asi kuyerera kunoratidza mutemo Q∝A·v attenuation.
Kunyange zvazvo simba reshaft richiderera ne8-12% nekuderera kwekuyerera, kusimba kwekudengenyeka kunokonzerwa nekudzvinyirira pulsation kunogona kuwedzera ne 20-30%, kunyanya pedyo nekumhanya kwakaoma, izvo zviri nyore kukurudzira resonance yemaitiro.

2. Ukama pakati pemusoro nekumanikidzwa: Musoro wezvinyorwa unoramba usina kuchinjwa, kudzvinyirirwa kwechokwadi kunoshanduka
Musoro weoretical unoramba usina kuchinjwa:Musoro weiyo theoretical we impeller inotarirwa nejometri parameters uye haina kuwirirana kwakananga nedhayamita yekubuda kwemvura.
Iyo throttling mhedzisiro ichawedzera kubuda kwekumanikidza kwepombi: Kana iyo system yekushanda pombi inofamba ichitevedza HQ curve uye yekunze nharaunda ichichinja (sekushanduka kwepombi network kuramba), iyo pressure fluctuation amplitude inowedzera ne30-50%, uye kufanotaura kwesimba kunodiwa kuburikidza nekumanikidza-kuyerera kwehunhu curve.
