1. Mosebetsi oa pompong:

Ho tloha mosebetsing ho ka khoneha ho khetha pompo ka lebaka la lichate tse bontšitsoeng ka & quot; performancecurves / technical & quot; data.

Dintlha tsa dimensional:

Ha ho hloekisa pompe ho latela lits'ebetso tse latelang: • Ho hlokahala hore phallo le khatello e be boemong ba ho khaola. • Mocheso oa khatello ka lebaka la bophahamo bo fapaneng. • Mocheso o lahleheloang ke pipeworkork (Hf) ho Tlhaloso ea 1) E ka 'na ea e-ba ea sebele. • Molemo o moholo ka ho fetisisa lefapheng la mosebetsi o lekanyelitsoeng.â € ¢ NPSH ea bohlokoa. • Bakeng sa palo ea boleng ba NPSH, bona setšoantšo se lekanang le li-curves.

3. Ho atleha ka pompo:

Pele o etsa qeto ea mokhoa o nepahetseng ka ho fetisisa o sebetsang, opereishene ea pampiri e lokela ho tsejoa. Haeba pampiri e lebeletsoe hore e sebetse e le sebaka se le seng sa mosebetsi, joale khetha pompo ea BL e sebetsang sebakeng sa mosebetsi o tsamaisanang le katleho e ntle ea pompo.
As the pump is sized on the basis of the highest possible flow, it is important always to have the duty point to the right on the efficiency curve(eta) in order to keep efficiency high when the flow drops.

4. Pumpo ea lisebelisoa:

Ho khethoa ha pompo ho itšetlehile ka khatello e lekantsoeng le mosebetsi oa pipe. pompo e fana ka mefuta e sa tšoaneng ea ftexible kgokahanyo e kang:
