摘　　要：采用主机复合驱动形式的耙吸船,在吹填作业中往往因吹填管线较短、管径过大、吹填输送浓度较高等因素,柴油机会发生超负荷现象,导致螺旋桨功率不足,造成安全隐患。为此,采用理论计算及设备性能操作分析方法,进行超负荷及功率分配问题的研究,提出抛艏艉双锚、主机功率分配优化等措施。结果表明,柴油机功率分配提高后,可以有效解决超负问题,大幅提高耙吸船吹填施工生产率。The main engine-driven trailing suction dredger is often overloaded due to short hydraulic filling pipeline,large pipe diameter,and high concentration of hydraulic filling transportation,resulting in insufficient propeller power and potential safety hazard.Therefore,we study the overload and power distribution by theoretical calculation and equipment performance operation analysis and put forward measures such as throwing bow and stern double anchors and optimizing power distribution of the main engine.The results show that after the power distribution of the diesel engines is improved,we can effectively solve the problem of overburden and greatly improve the productivity of the dredger suction.
