研究了单缸双作用隔膜泵输送矿浆流体脉动峰值分散技术。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和公式,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。最后阐述了峰值分散技术在输送水煤浆往复泵组中的实际运行情况。
The single-cylinder double-action diaphragm pump pulsating peak dispersion technology was studied. On the premise of analyzing the causes of the flow pulsation and pressure pulsation in a single reciprocating pump, the reasons for the peak superposition of multiple CW pumps when they are delivered to the same pipe and the conditions for eliminating the peak superposition are discussed. The optimum dispersion phase Angle value, software calculation and judgment methods and formulas, the concept of peak dispersion technology and the effect of accumulator on the pulsation are deduced. The relationship between the parameters of air chamber and the attenuation rate of flow pulsation is presented. Finally, the actual operation of peak dispersion technology in transporting coal-water slurry reciprocating pump is described.
