在重庆升降平台液压传动系统中，可能有人认为通过改变加速度来控制电机是错误的，他们的理论是一般液压使用的电机运转速度是恒定的，机械能转换为液压动能，若改变液压泵是不合适的，加大液压泵的输出值会造成液压泵甚至整个液压系统损坏，所以这些人认为需要通过改变节流阀来控制液压油在管道中的移动速度，因而来改变加速。
In Hangzhou lifting platform hydraulic system, some people may think that by changing the acceleration to control the motor is wrong, their theory is a hydraulic motor speed is generally used is constant, the mechanical energy is converted to kinetic energy of hydraulic, if it is inappropriate to change the pump , increase the pump output will cause the value of the hydraulic pump or the hydraulic system damage, so these were deemed necessary by changing the throttle valve to control the moving speed of the hydraulic oil in the pipeline and thus to change the acceleration.

在升降平台液压传动系统中，可以确定的是通过液压回路的调整来改变执行部件运动速度，这种方法是正确的，但如果按照上述文中说的只通过节流阀来改变速度是不正确的方法。
In Hangzhou lifting platform hydraulic system, it is certain that by adjusting the hydraulic circuit to change the velocity of execution units, this approach is correct, but in terms of the above text says only be changed by the throttle speed is incorrect method.
