Water pump "rated lift: 6m" what do you mean?
Popularly speaking, "lift head" is the ability of water pump to lift water. 6m means that the pump can pump water to the height of 6m.
Lift refers to the weight of fluid per unit weight after the pump, the pump is an important working parameter, also known as pressure head. Simply stated: rated lift 6M refers to the rated operating conditions of the pump, the increase of energy 6M water column height. Here's an example to help you understand:Example 2-1 the head of a centrifugal pump is now measured. The refrigerant is 20 DEG C water, the measured flow rate is 60m^3/h, vacuum pump inlet meter 0.02Mpa, outlet pressure gauge readings for the 0.47Mpa (g), the two known table between the vertical distance is 0.45M if the suction pipe of same diameter and pipe pressure pump, calculate the pump head.Solution:Check the water density at 20 centigrade 1.0*10e3kg/m3,H=0.45m (1Mpa approximately equal to 100 m water column)P exports =0.47Mpa (0.47*100 m water column, =47 m water column)P imports =-0.02Mpa (0.02*100 m water column, =2 m water column)P is the density of the liquidH=h+ (P -p / P g=0.45+ export import) (0.47*10e6- (-0.02*10e6)) / (10e3*9.887) =50.5m (water)
