Reciprocating pumps convert rotary motion to linear motion. Pump speed in RPM determines the pumps output volume for any given combination of cylinder bore and piston stroke.

循环泵将曲轴旋转运动转化为柱塞的直线运动。泵速转每分钟决定了任何气缸和活塞组合的排泵量。

Reciprocating pump flow and pressure head has nothing to do with the pump cylinder size, and the reciprocating frequency of the piston stroke.

往复泵的流量与压头无关，与泵缸尺寸、活塞冲程及往复次数有关。

Piston stroke length of 1, as well as the piston per minute species reciprocating cylinder liner at the number (referred to as red pump or pump a few) n-related.

活塞行程长度1，以及活塞每分种在缸套种往复的次数n有关。
