【摘要】 讨论了具有3个从动轮的平面式并联齿轮泵的结构原理,给出了排量、平均流量、瞬时流量和流量脉动率的计算公式。分析了其流量脉动情况,结论指出,在齿数相同时,该泵的排、平均流量和瞬时流量均比普通齿轮泵增加了3倍,从而提高了泵的功率密度,当取齿数Z=3K±1时,该种泵具有很好流量均匀性,它适用于对流量品质要求高的场合。更多还原

【Abstract】 The flow pulsation in a plane-parallel gear pump with 3-idlers was analyzed,formulae for calculating displacement,average flow velocity,instantaneous flow and pulsation flow were derived.It was pointed out that this sort of gear pump can provide higher flow pulsation frequency when taking teeth number Z=3K±1.更多还原
