Why is the height of the water pump diversion is limited?

        Because the pump suction is formed by vacuum suction pipe, the pressure on the water pressure into the water pump suction pipe, and atmospheric pressure is constant, the water pump pipe height is too high, beyond the atmospheric pressure of the pressure range, can not inhaled water .

        Atmospheric pressure of 10 meters of water a little more (10.33 m), in theory, as long as no more than this height can, but in fact because of altitude, resistance and other factors, in practice the suction pipe installation height is lower than this figure , About 7 - 8 meters.
