Isantya esithe ngqo
1. Inkcazo yesantya esithe ngqo
Isantya esithile sempompo yamanzi sifinyeziwe njengesantya esithile, esidla ngokumelwa sisimboli ns. Isantya esithile kunye nesantya sokujikeleza zizinto ezimbini ezahlukeneyo ngokupheleleyo. Isantya esithile yidatha ebanzi ebalwa ngokusebenzisa iiparitha ezisisiseko Q, H, N, ezibonisa iimpawu zempompo yamanzi. Isenokuthiwa yikhrayitheriya ebanzi. Ihambelana ngokusondeleyo kwisakhiwo se-pump impeller kunye nokusebenza kwempompo.
Ifomula yokubala yesantya esithe ngqo eTshayina
Ifomula yokubala yesantya esithe ngqo phesheya
1. U-Q kunye no-H babhekisela kwisantya sokuhamba kunye nentloko kwizinga eliphezulu kakhulu, kwaye n ibhekisela kwisantya sokuyila. Kwimpompo efanayo, isantya esithile sixabiso elithile.
2. I-Q kunye ne-H kwifomula ibhekisela kwisantya sokuhamba koyilo kunye nentloko yoyilo lwempompo yenqanaba elilodwa lokufunxa. I-Q/2 ifakwa endaweni yempompo yokufunxa kabini; Kwiimpompo zamanqanaba amaninzi, intloko ye-impeller yesigaba sokuqala kufuneka ithathelwe indawo yokubala.
| Isimbo sempompo | Impompo ye-Centrifugal | Impompo edibeneyo yokuhamba | Impompo yokuhamba kweAxial | ||
| Isantya esithile esisezantsi | Isantya esithile esiphakathi | Isantya esiphezulu esithile | |||
| Isantya esithile | 30<ns<80 | 80<ns<150 | 150<ns<300 | 300<ns<500 | 500<ns<1500 |
1. Ipompo enesantya esithile esisezantsi ithetha intloko ephezulu kunye nokuhamba okuncinci, ngelixa ipompo enesantya esiphezulu ithetha intloko ephantsi kunye nokuhamba okukhulu.
2. I-impeller enesantya esincinci esincinci sincinci kwaye side, kwaye i-impeller enesantya esiphezulu sibanzi kwaye sifutshane.
3. Ipompo yesantya esezantsi iqhelekile kwi-hump.
I-4, impompo yesantya esezantsi, amandla e-shaft amancinci xa ukuhamba ku-zero, ngoko vala ivalve ukuqala. Iimpompo zesantya esiphezulu esikhethekileyo (impompo yokuqukuqela exutyiweyo, impompo ye-axial flow) inamandla amakhulu e-shaft kwi-zero flow, ngoko ke vula ivalve ukuqalisa.
