【摘要】：節(jié)能減排是創(chuàng)建和諧社會(huì),走可持續(xù)發(fā)展路線的重要環(huán)節(jié),修造船行業(yè),尤其是疏浚工程船的建造、修理和維護(hù),疏浚機(jī)具的制造和修理等都涉及到大量的能源、材料的消耗。而應(yīng)用在疏浚工程船上如何節(jié)能減排,是一個(gè)很嚴(yán)峻的問(wèn)題。本文主要分析目前國(guó)內(nèi)疏浚船舶效率不高,尤其是疏浚機(jī)具施工效率較低、穩(wěn)定性不高的原因,并通過(guò)實(shí)例探索研究如何通過(guò)改進(jìn)疏浚機(jī)具尤其是泥泵的結(jié)構(gòu)、效率、材料等,進(jìn)行實(shí)船測(cè)試和施工,進(jìn)而為未來(lái)疏浚機(jī)具的高效研發(fā)和利用、現(xiàn)有疏浚船舶的疏浚機(jī)具的改造提供理論和實(shí)效依據(jù),進(jìn)一步提高疏浚船舶的施工效率,從而全面達(dá)到節(jié)能減排的目的。在技術(shù)改造過(guò)程中,運(yùn)用了計(jì)算流體力學(xué)技術(shù)(CFD)、有限元分析軟件ANSYS作為模擬分析手段,驗(yàn)證優(yōu)化的合理性,此外在“新海鯉”輪泥泵優(yōu)化中,還運(yùn)用了泵殼改進(jìn)后的強(qiáng)度校核分析、模型泵試驗(yàn)的方法與數(shù)值模擬結(jié)合的方法,進(jìn)一步提高了優(yōu)化的可行性和合理性,并最終實(shí)船應(yīng)用測(cè)試,取得了良好的效果。實(shí)船效果表明,利用流體力學(xué)軟件進(jìn)行模擬計(jì)算并應(yīng)用于實(shí)踐的這套方法的探索初具成效,可以作為今后類似狀況的疏浚泥泵的節(jié)能減排的技術(shù)路線和研究方向,為今后研究設(shè)計(jì)新型高效泥泵奠定了基礎(chǔ),同時(shí)也為我國(guó)疏浚裝備的發(fā)展和國(guó)產(chǎn)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.
