摘　　要：针对回油节流调速回路活塞杆侧容易压力偏高,对液压密封件造成较大损害的情况,通过对有减压阀的回路与无减压阀的回路对比,发现使用减压阀来控制这个压力可延长该系统的使用寿命。Meter-out system makes the pressure on the side of piston rod in hydraulic cylinder more than our expectation,it harms the seal components.By comparing the hydraulic circuits with pressure reducing valve and without pressure reducing valves,the article points out controlling the pressure through pressure reducing valve can prolong the life of the system.

关 键 词：减压阀 回油节流调速 活塞杆
