I. Flow rate
Flow rate: refers to the amount of liquid discharged by the slurry pump per unit time. There are two ways to express it, namely volume force Q and mass flow rate Qc
The unit of volume flow rate is "m³h", "L/S"
The unit of weight flow rate is "t/h", "kgf/h"
The relationship between volume flow rate and weight flow rate is: Qc=YQ
Y represents the specific gravity (heavyness) of the slurry, kgf/m³
II. Head
The increase in energy per unit weight of liquid after passing through the slurry pump is equal to the algebraic difference between the water head at the outlet of the slurry pump and the total water head at the inlet, in meters of water column (mH2O), that is, the delivery height of the slurry pump.
III. Speed n
Indicates the number of times the slurry pump shaft rotates per minute, in r/min
IV. Power
The power of the slurry pump includes:
Output power Pe: the work done on the fluid flowing through the pump per unit time.
Input power P: refers to the power delivered to the pump shaft by the motor.
Matching power Pg: rated output power of the motor, generally the matching power is larger than the shaft power.
V. Efficiency
The difference between the input power and output power of the pump is the ratio of the power loss in the pump.
