Isivinini Esiqondile
1. Incazelo yesivinini esithile
Ijubane elithile lephampu yamanzi lifushaniswa njengejubane elithile, elivame ukumelwa uphawu lwe-ns. Ijubane elithile kanye nejubane lokujikeleza kuyimiqondo emibili ehlukene ngokuphelele. Ijubane elithile liyidatha ephelele ebalwa ngokusebenzisa amapharamitha ayisisekelo u-Q, u-H, u-N, abonisa izici zephampu yamanzi. Lingabizwa nangokuthi i-criterion ephelele. Lihlobene eduze nesimo sesakhiwo sephampu kanye nokusebenza kwephampu.
Ifomula yokubala ye-Specific Speed eShayina
Ifomula yokubala ye-Specific Speed phesheya
1. U-Q no-H babhekisela esilinganisweni sokugeleza kanye nekhanda ekusebenzeni kahle kakhulu, kanti u-n ubhekisela esivinini sokuklama. Kuphampu efanayo, isivinini esithile siyinani elithile.
2. I-Q kanye ne-H kufomula zibhekisela esilinganisweni sokugeleza komklamo kanye nekhanda lomklamo wephampu eyodwa yokumunca eyodwa enesigaba esisodwa. I-Q/2 ithathelwa indawo yephampu yokumunca kabili; Kumaphampu anezigaba eziningi, ikhanda le-impeller yesigaba sokuqala kufanele lithathelwe indawo yokubala.
| Isitayela sephampu | Iphampu ye-centrifugal | Iphampu yokugeleza okuxubile | Iphampu yokugeleza kwe-Axial | ||
| Isivinini esithile esiphansi | Isivinini esimaphakathi esithile | Isivinini esiphezulu | |||
| Isivinini esithile | 30 | 80 | 150 | 300 | 500 |
1. Iphampu enejubane eliphansi elithile lisho ikhanda eliphezulu kanye nokugeleza okuncane, kanti iphampu enejubane eliphezulu elithile lisho ikhanda eliphansi kanye nokugeleza okukhulu.
2. I-impeller enejubane eliphansi elithile incane futhi yinde, kanti i-impeller enejubane eliphezulu elithile ibanzi futhi imfushane.
3. Iphampu yesivinini esiphansi ithambekele ekuqhumeni.
4, iphampu yesivinini esithile esiphansi, amandla omgodi mancane uma ukugeleza kungu-zero, ngakho vala ivalvu ukuze uqale. Amaphampu esivinini esithile esiphezulu (iphampu yokugeleza exubile, iphampu yokugeleza ye-axial) anamandla amakhulu omgodi lapho ukugeleza kungu-zero, ngakho vula ivalvu ukuze uqale.
