stroke of piston

As the working stroke of the telescopic sleeve cylinder is longer than that of the conventional, there is a clearance between the piston and cylinder bore as well as between the rod and guide sleeve which will cause cylinder break under heavy loading.

伸缩套筒式油缸的工作行程大，活塞与缸体内径间、活塞杆与导向套间都存有间隙，承受重载时容易引起屈曲破坏，为此应确定整体稳定的极限力。

According to the simulation calculation results of piston slapping, we can see that the radical acceleration and tilting angular acceleration of the piston near the top dead center in the combustion stroke are most, so the piston slapping is the most serious.

根据活塞敲击运动仿真计算结果发现活塞在燃烧上止点附近的径向加速度以及绕销轴的摆动加速度最大，从而导致活塞对缸套的敲击也最大。

Pump speed in rpm determines the pumps output volume for any given combination of cylinder bore and piston stroke.

泵速转每分钟决定了任何气缸和活塞组合的排泵量。
