液压系统是绞车的核心组成部分,负载敏感技术因其节能、高效得到越来越多的应用。通过分析负载敏感泵的原理,在AMESim中建立负载敏感泵的模型并验证其正确性,将负载敏感泵应用于绞车液压系统中。仿真结果表明,负载敏感型液压系统能够根据负载变化及节流调速的要求,实时调整泵的排量和出口压力与系统需求相匹配,减少了系统能量损失。 Hydraulic system is the core part of the winch, load-sensing technology because of its energy-saving, efficient and more and more applications. By analyzing the principle of load-sensitive pump, a model of load-sensing pump is established in AMESim and the correctness of the model is verified. The load-sensing pump is applied to winch hydraulic system. The simulation results show that the load-sensitive hydraulic system can adjust the pump displacement and outlet pressure in real time to match the system requirements according to the load variation and throttling speed regulation, reducing the system energy loss.
