Abstract
PURPOSE: To prevent pulsation by arranging a plurality of 1/4 wave-length pipes on a water feeding pipe and allowing said wave-length pipes to correspond to the variation of the revolution number of a pump.
CONSTITUTION: Within the range in which the belly part 72 of the stationary wave of the pressure pulsation which is generated in the water-feeding pipe 4 of a variable speed pump 1 shifts when the revolution number of the pump is varied within a fixed range, wave-length pipes 6a-6c having the 1/4 length of the wave-length of each pulsation wave which corresponds to each prescribed revolution speed are mounted on the water-feeding pipe 4, adjusted to the belly part 7aW7c of each stationary wave. A regulator valve 8 is fitted at the end of piping of each 1/4 wave- length pipe, and said regulator valve is connected to the control valve which opens only the corresponding regulator valve through detection of the prescribed revolution speed. As the 1/4 wave-length pipes having the position and length corresponding to the revolution number are provided for the variation of the revolution number of the pump, this constitution allows pulsation wave to be reduced over the all revolution control range.
