Sand Dredge Pump Characteristics
China dredger sand pump manufacturer
The curve of pumping a certain amount of slurry in a pipeline with the amount of energy required (Hman-Q), Pump output power (Wout)-Q and η-Q ( η pump working efficiency in certain amount of capacity, head and rotating speed rpm).
Under the affinity laws, we can see that pump are able to produce different working capacity in different rotating speed when working head is stable, larger working pressure with higher rotating speed when working capacity is in certainty, and different pump output as well as different working efficiency.
Pump is operated or driven system in a region of the constant speed or the constant torque.
