摘要
针对“新海马”轮实际施工中存在效率偏低、适应性较差等问题,比选同类型船舶泥泵性能参数,优化泥泵叶轮设计。采用叶轮直径更小、转速更高的泥泵方案,其具有叶墙宽度大、球形通道截面为宽口等特点,并对泥泵的工程应用效果进行分析。结果表明,高效泥泵可拓展船舶的适用性,在提高挖泥及艏吹效率的同时降低船舶能耗,为耙吸式挖泥船泥泵选型提供参考。
In view of the problems of low efficiency and poor adaptability in the actual construction of“Xinhaima”ship,we compare and select the performance parameters of dredge pumps of the same ship type,optimize the impeller design of dredge pump,apply the dredge pump scheme of smaller impeller diameter and higher rotation speed with the characteristics of wide blade wall width,wide spherical area and etc,and analyze the engineering application effect of dredge pump.The results show that the high efficiency dredge pump can expand the applicability of the ship,improve the efficiency of dredging and bow blowing,and reduce the energy consumption of the ship,which can provide the references for the dredge pump selection of trailing suction hopper dredger.
