摘要
针对煤矿井下大流量泥浆泵车的使用要求以及开式液压系统和闭式液压系统的特点,提出了大流量泥浆泵车液压系统的总体方案。详细叙述了液压系统中泥浆泵马达回转系统和履带行走系统的组成元件、工作原理及主要液压部件功能。根据泥浆泵车的性能要求对液压系统中重要元件进行了参数计算和选型。考虑到煤矿井下工作环境及闭式液压系统的应用,在液压系统中采取了三种相应的冷却措施来提高系统的散热效果,并对冷却器进行了计算选型以满足大流量泥浆泵车液压系统的散热需求,能较好地适应于煤矿井下应用。
According to the application requirements of large flow mud pump truck and the characteristics of open hydraulic system and closed hydraulic system,the overall design of hydraulic system of large flow mud pump truck is designed.The components,working principle and functions of main hydraulic components of mud pump motor rotary system and crawler walking system are described in detail.Based on the performance requirements of mud pump truck,the important hydraulic components are calculated and selected.Considering the requirement of working environment and the application of closed hydraulic system in underground coal mine,three cooling measures are adopted to improve the heat dissipation effect of the system,and also the cooler is calculated and selected to meet the requirement of heat dissipation of hydraulic system of large flow mud pump truck,which can be used well in underground coal mine.
