The length of these phases is often measured in pump strokes rather than volume directly or time.
这些阶段的长度一般用泵冲测量而不是直接用体积或时间来测量。
The calculating formulas for the power of single stroke, utilization efficiency of energy and frequency of strokes are derived from the energy equation of the reciprocating pump.
并根据往复泵的能量方程推导了液动冲击器的单次冲击功、能量利用率和冲击频率的计算公式，并利用实测数据进行了验证。
