| 摘 要： | :试验结果发现 ,当行程加大时 ,获得较高的冲锤末速度 (5 .43m/s) ,单次冲击功 34 6 .45J。当活塞运动所需瞬时流量已大大超过了水泵供水的供给量时 ,冲击器仍能稳定地工作 ,这体现了射流冲击器作为一开放的系统所特有的流量可自动补偿的优点。射流冲击器对负载的适应能力较高 ,且在大行程条件下 ,增加锤重可较大幅度地提高单次冲击功。

| Abstract: | The experiment shows that the final impacting velocity of hammer has reached 5.34 m/s, and the single impacting energy has reached 346.45 J, when the displacement was lengthen. Instantaneous flow has exceeded greatly the pump flow, but the hammer can still work steadily, which means that as a opening system the fluidic efflux hammer has its own advantage of flow auto-compensating. The efflux hammer has good adaptive ability to lode, and single impacting energy can be enhanced greatly by increasing weight of the hammer under the condition of long displacement. |
