Isantya Esithile
1. Inkcazo yesantya esithile
Isantya esithile sempompo yamanzi sifinyezwa njengesantya esithile, esidla ngokumelwa luphawu lwe-ns. Isantya esithile kunye nesantya sokujikeleza ziingcamango ezimbini ezahlukeneyo ngokupheleleyo. Isantya esithile yidatha epheleleyo ebalwe ngokusebenzisa iiparameter ezisisiseko ze-Q, H, N, ezibonisa iimpawu zempompo yamanzi. Ingabizwa ngokuba yi-criterion epheleleyo. Inxulumene ngokusondeleyo nokwakheka kwe-impeller yempompo kunye nokusebenza kwempompo.
Ifomula yokubala isantya esithile eTshayina
Ifomula yokubala yesantya esithile phesheya
1. U-Q no-H babhekisa kwisantya sokuhamba kunye nentloko ekusebenzeni kakuhle kakhulu, kwaye u-n ubhekisa kwisantya soyilo. Kwimpompo efanayo, isantya esithile sixabiso elithile.
2. I-Q kunye ne-H kwifomyula zibhekisa kwisantya sokuhamba koyilo kunye nentloko yoyilo yepompo enye efunxayo inqanaba elinye. I-Q/2 ithathelwa indawo yepompo efunxayo kabini; Kwiipompo ezininzi, intloko ye-impeller yenqanaba lokuqala kufuneka ithathelwe indawo yokubala.
| Isitayile sepompo | Impompo ye-centrifugal | Impompo exutyiweyo | Impompo yokuhamba kwe-Axial | ||
| Isantya esiphantsi | Isantya esiphakathi esithile | Isantya esiphezulu | |||
| Isantya esithile | 30 | 80 | 150 | 300 | 500 |
1. Impompo enesantya esiphantsi ithetha intloko ephezulu kunye nokuhamba okuncinci, ngelixa impompo enesantya esiphezulu ithetha intloko ephantsi kunye nokuhamba okukhulu.
2. I-impeller enesantya esiphantsi incinci kwaye inde, kwaye i-impeller enesantya esiphezulu ibanzi kwaye imfutshane.
3. Ipompo yesantya esiphantsi inokuba ne-hump.
4, ipompo yesantya esithile esiphantsi, amandla eshaft mancinci xa ukuhamba kungenanto, ngoko ke vala ivalvu ukuze uqalise. Iipompo zesantya esithile esiphakamileyo (ipompo yokuhamba exutyiweyo, ipompo yokuhamba kwe-axial) zinamandla amakhulu eshaft xa ukuhamba kungenanto, ngoko vula ivalvu ukuze uqalise.
