在重慶升降平臺(tái)液壓傳動(dòng)系統(tǒng)中，可能有人認(rèn)為通過(guò)改變加速度來(lái)控制電機(jī)是錯(cuò)誤的，他們的理論是一般液壓使用的電機(jī)運(yùn)轉(zhuǎn)速度是恒定的，機(jī)械能轉(zhuǎn)換為液壓動(dòng)能，若改變液壓泵是不合適的，加大液壓泵的輸出值會(huì)造成液壓泵甚至整個(gè)液壓系統(tǒng)損壞，所以這些人認(rèn)為需要通過(guò)改變節(jié)流閥來(lái)控制液壓油在管道中的移動(dòng)速度，因而來(lái)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(tái)液壓傳動(dòng)系統(tǒng)中，可以確定的是通過(guò)液壓回路的調(diào)整來(lái)改變執(zhí)行部件運(yùn)動(dòng)速度，這種方法是正確的，但如果按照上述文中說(shuō)的只通過(guò)節(jié)流閥來(lái)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.
