By rotating impeller pump liquid for power, the liquid energy (including kinetic and pressure energy) increase 250ZJ-I-A78 slurry pump, in the interaction, the speed and pressure of the liquid is changed. Typically, centrifugal impeller inlet pressure lowest place. If the pressure in this place is equal to or lower than the liquid temperature at the vapor pressure of the liquid Pv, steam and gases will be dissolved in the liquid escaping from a large number of liquid, vapor and gas mixture to form a plurality of small bubbles 250ZJ-I- When A80 slurry pump, these small bubbles with the liquid flow to a high pressure area, since the vapor pressure inside the bubble 250ZJ-I-A83 slurry pump, but around the bubbles is greater than the vapor pressure, it creates a pressure difference, the pressure difference in the slag pump, the bubbles burst by pressure re-condensation. Shaft power and the difference between the effective power, is the loss of power of the pump, the size of the pump efficiency to calculate the efficiency of the pump is effective power and shaft power ratio, namely η = Ne / NZ (1-8) represented by the formula ( 1-7) (1-8) of the pump shaft power can be obtained as: Ne = QH Sm / 102η KW (1-9) slurry pumps, 250ZJ-I-A85 slurry pump, accessories Daquan (certified merchants) from Shijiazhuang Stone sent Pump Limited.
