在重慶升降平臺液壓傳動系統中，可能有人認為通過改變加速度來控制電機是錯誤的，他們的理論是一般液壓使用的電機運轉速度是恒定的，機械能轉換為液壓動能，若改變液壓泵是不合適的，加大液壓泵的輸出值會造成液壓泵甚至整個液壓系統損壞，所以這些人認為需要通過改變節流閥來控制液壓油在管道中的移動速度，因而來改變加速。
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.

在升降平臺液壓傳動系統中，可以確定的是通過液壓回路的調整來改變執行部件運動速度，這種方法是正確的，但如果按照上述文中說的只通過節流閥來改變速度是不正確的方法。
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.
