Electro-hydraulic control method of pump truck
The invention relates to an electro-hydraulic control method of a pump truck. The electro-hydraulic control method comprises the following steps that gears of an engine are divided into a low-gear area and a high-gear area according to the increasing rotating speed of the engine; the low-gear area is divided into at least two gears according to the increasing rotating speed of the engine; when therotating speed of the engine is in the low-gear area, oil is supplied to all oil cylinders through a oil pumps; when the rotating speed of the engine is in the high-gear area, oil is supplied to allthe oil cylinders through c oil pumps; and c is larger than a, and all the oil pumps work alternately. The electro-hydraulic control method is applied to the technical field of concrete pump trucks.
本发明涉及一种泵车的电液控制方法,包括以下步骤:根据发动机递增的转速将发动机的档位分为低档位区和高档位区;根据发动机递增的转速将低档位区划分出至少两个档位;发动机的转速处于低档位区时,通过a个油泵给各油缸供油;发动机的转速处于高档位区时,通过c个油泵给各油缸供油;其中,c大于a,各油泵交替工作。本发明应用于混凝土泵车技术领域。
