Characteristics of the so-called head of the whole (also known as the characteristics of non-overload) is the power curve increases with the flow speed is very slow, even better is that when the flow increased to a certain a certain value, not only will not increase power, it will be decline in the power curve means that there is a hump of the curve, if so, we choose as long as the motor rated power hump point slightly more than the value of the power, then the flow in the 0 to the maximum flow of the whole area, and you both in one working condition points to run, will not pump more than the power of pump motor overload power for the pump with such a performance, whether it is selection or use, will be very convenient.
所谓的全扬程特性是指功率曲线随流量增加而上升的速度非常缓慢，更理想的是当流量增加到某一定值时，功率不但不会再上升，反而会有所下降，也就是说功率曲线是一根有驼峰的曲线，如果这样的话，我们只要选择电机额定功率略超过驼峰点的功率值，那么在0流量到最大流量的整个范围内，你无论在那一个工况点上运行，泵的功率都不会超过电机功率而使泵过载，对于具备这种性能的泵，无论是选型还是使用时，都会非常方便。
First of all, the energy saving control of hydraulic excavator in China and aboard are related, and the control methods are summarized in this paper. For the sake of energy saving control research, a hydraulic excavator electronic energy-saving control model is established based on CAN-bus technique. And then the aspect of the speed control of the engine is focused on, a cascade control is used, an inner feedback loop gives control over the governing throttle and an outer feedback loop does the speed regulation. The use of feed forward of the load demand, when a signal is available which is proportional to the load, then the signal can be fed forward to the input of the control system to anticipate changes in load. The power limiting control ensures optimum use of the power required for the excavator under varying operating conditions and avoids overload of the diesel engine, with the diesel engine, variable pump, and the loads as the whole dynamic system, the overall power match technique is proposed, and transfered the point match to area match by the method of area power match, so the energy efficiency is improved.
