潼关清淤使用射流和扰流两种设备。射流设备的作用是冲刷河床扬动泥沙 ,射流能力取决于水枪口径和出口流速。穿过水层后射流速度减小 ,冲刷速度迅速降低 ,因此 ,使用时水枪距河底不能太远 ,应有合适的入射角和一定航速 ,才能有效地冲刷河床。扰流设备的作用是扰动水流 ,增加水流的紊动强度 ,干扰泥沙落淤。扰流设备效率主要取决于其转动速度 ,使用时应快速行驶
Tongguan dredging using jet and spoiler two kinds of equipment. The role of jet equipment is to flush the riverbed to lift sediment. The jet capacity depends on the caliber of the gun and the outlet flow rate. After passing through the water layer, the jet velocity decreases and the erosion rate decreases rapidly. Therefore, the water gun can not be far away from the river bottom when it is used. It should have a suitable angle of incidence and a certain speed to effectively flush the riverbed. The function of the spoiler is to disturb the water flow, increase the turbulence intensity of the water flow, and disturb the sediment siltation. The efficiency of spoiler equipment mainly depends on the speed of its rotation, should be used quickly
