reverse circulating
例句与用法
- Specially , the rotating ramjet with shaft power output was discussed . result showed that the thermodynamic cycle of the rotating ramjet is a breton cycle including two anti - cycle processes . because the advantage on thermodynamic performances and structure , the rotating ramjet will has wide prospective application in aircraft and powers system in heavy trucks , military facilities , tanks , warship as well as power plant
着重讨论了轴功输出方案的旋转冲压发动机,初步分析表明,旋转冲压发动机的热力循环是加进了两个反循环的布雷顿循环,该发动机在热力性能和结构方面与燃气轮机相比有独特优点,有望在现代和未来各类飞行器及各类重型车辆、战略设施、坦克、舰船动力、电力等能源动力领域获得广泛应用。 - This drilling adopts crank connecting link and walking beam percussion mechanism , which make the drilling possess two percussive functions , normal drilling takes connecting link impact as main mode , when encountering special situation and the connecting link impact can not drill , it can transform into hoisting impact , the stroke length can be modulated , it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism , these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag , which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum , but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist , which not only ensures the balance state of drilling tool , but also reduces the mechanical design , and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising , and reduces the assistant operating time
该钻机采用曲柄连杆、游梁式冲击机构，使钻机具有两种冲击功能;正常钻进以连杆冲击为主，遇到特殊情况，用连杆冲击不能钻进时，可转为卷扬冲击，冲程可调，因连杆冲击机构连续工作，所以实现了自动冲击钻进，可提高钻进效率，减轻劳动强度;采用泵吸反循环的方式排渣，既能有效解决卵砾石地层、坚硬地层等特殊地层钻进的困难，又很好地解决了冲击钻机效率低下的问题;采用直齿圆柱齿轮差速机构作为主卷扬的双筒同步机构，既保证了钻具处于平衡状态，又大大简化了该机构设计，降低了成本;该钻机底盘行走移位采用步履式;钻塔采用液压起立，减少了辅助作业时间。
