| Abstract: | After analyzing the movement pattern of the reciprocating pump ,give out the formulas of the double pumps parallel operation cumulative flow and the flow uneven coefficient . Program the movement with the Excel functions to simulate high‐pressure liquid ammonia pump parallel operation cumulative flow ,discuss the uneven coefficient variation of double pumps operating in the different phase angle and different speeds .Sum up the best operation condition ,and propose the idea of the peak dispersion technology . |
