摘　　要：该文介绍了用于石油钻杆加工的管端加厚液压机。针对该液压机流量大、压力高和运动惯量大所造成的稳定性能差、换向卸荷振动冲击大等问题,通过对其系统原理与工作振动现象进行深入的分析,发现充液阀无法充分卸压和卸压延时不足是其产生振动冲击、造成稳定性能差的主要原因;最后提出了合理有效的技术方案,解决了该液压机油缸卸压回程时产生的振动冲击,提高了其工作时稳定性能。This paper describes the oil drill pipe hydraulic which for the processing of oil drill pipe ends. For this hydraulic machine with the poor stable performance, commutation unloading big shock and vibration problems that caused by the large inertia movement, the high pressure and large flow. Through in-depth analysis of its system working principle and working vibration phenomena, found that the filling valve not fully discharge pressure and inadequate relief delay, causing the main reason for vibration impact and poor performance stability. Finally, a reasonable and effective technical solutions to address the impact of the hydraulic cylinder vibration generated when the relief return, im- prove performance and stability of its work.
