摘要
在分析单台往复泵流量脉动及压力脉动产生原因的前提下,论述了多台泵向同一管路输送水煤浆时产生峰值叠加的原因及消除峰值叠加的条件,给出了最优分散相角值及软件计算判断方法及公式,提出了峰值分散技术的概念,以及蓄能器对脉动的消减作用,空气室结构参数与流量脉动衰减率的关系。
On the premise of analyzing the cause of flow pulsation and pressure pulsation of single reciprocating pump, the cause of peak value overlapping in water coal syrup transporting to one pipeline with multi - unit pumps, and the conditions to eliminate peak overlapping are discussed. The graphic analysis of distinguishing optimum dispersion phase angle, the methods and the formula of software calculation are give. The concept of peak value dispersion technology are put forward. The accumulator decreases the function to the pulsation, air pack construction parameter and the relation of the discharge pulsation tapering rate.
