【摘要】：节能减排是创建和谐社会,走可持续发展路线的重要环节,修造船行业,尤其是疏浚工程船的建造、修理和维护,疏浚机具的制造和修理等都涉及到大量的能源、材料的消耗。而应用在疏浚工程船上如何节能减排,是一个很严峻的问题。本文主要分析目前国内疏浚船舶效率不高,尤其是疏浚机具施工效率较低、稳定性不高的原因,并通过实例探索研究如何通过改进疏浚机具尤其是泥泵的结构、效率、材料等,进行实船测试和施工,进而为未来疏浚机具的高效研发和利用、现有疏浚船舶的疏浚机具的改造提供理论和实效依据,进一步提高疏浚船舶的施工效率,从而全面达到节能减排的目的。在技术改造过程中,运用了计算流体力学技术(CFD)、有限元分析软件ANSYS作为模拟分析手段,验证优化的合理性,此外在“新海鲤”轮泥泵优化中,还运用了泵壳改进后的强度校核分析、模型泵试验的方法与数值模拟结合的方法,进一步提高了优化的可行性和合理性,并最终实船应用测试,取得了良好的效果。实船效果表明,利用流体力学软件进行模拟计算并应用于实践的这套方法的探索初具成效,可以作为今后类似状况的疏浚泥泵的节能减排的技术路线和研究方向,为今后研究设计新型高效泥泵奠定了基础,同时也为我国疏浚装备的发展和国产化提供了探索方向。
[Abstract]:Energy saving and emission reduction is an important link in building a harmonious society and taking a sustainable development route. The construction, repair and maintenance of dredging engineering vessels, the manufacture and repair of dredging tools and so on are all related to a large number of energy sources. Material consumption. How to save energy and reduce emissions on dredging ships is a very serious problem. This paper mainly analyzes the reasons for the low efficiency and stability of dredging vessels in China, especially in the construction of dredging machines and tools. And through an example to explore how to improve dredging equipment, especially mud pump structure, efficiency, materials, and so on, and how to carry out full-ship testing and construction, and then for the future dredging equipment efficient research and development and use. The modification of dredging machines and tools of existing dredging vessels provides theoretical and practical basis for further improving the construction efficiency of dredging vessels, so as to achieve the purpose of energy saving and emission reduction in an all-round way. Computational fluid dynamics (CFD) technique and finite element analysis software (ANSYS) are used to verify the rationality of the optimization. In addition, the improved strength checking analysis of the pump shell is also used in the optimization of "Xinhai carp" wheel mud pump. The combination of model pump test method and numerical simulation method further improves the feasibility and rationality of optimization, and finally, the application test of real ship has achieved good results. The actual ship effect shows that, The exploration of this method, which is simulated and calculated by hydrodynamic software and applied in practice, is of initial effect and can be used as the technical route and research direction for energy saving and emission reduction of dredging pumps in similar conditions in the future. It lays a foundation for the research and design of new high efficiency mud pump in the future, and also provides the exploration direction for the development and localization of dredging equipment in our country.
