| 波浪能压力泵是利用波浪能直接进行海水淡化的核心部件之一，其运行特性直接影响到波浪能海水淡化的效率。本文对振荡双浮子波浪能压力泵进行了物理试验研究，分析得到负载压强和波浪要素对波浪能泵出水流量和波浪能转换为液压能效率的影响规律。试验结果表明，对于固定尺寸的波浪能泵系统，存在着与之匹配的波浪周期条件，可取得最大流量和效率；波高越大，出水流量越大，效率越高；负载压强越大，流量越小，效率先增后减且存在着最优负载压强条件。 |
| 英文摘要: |
| Wave-driven pressure pump is the core component of the wave-powered desalination device and its operation performance directly influences on the efficiency of the device. In this paper an experimental study was conducted on the operation characteristics of a wave-driven pressure pump and the effect of load pressure and wave parameters on flow rate and efficiency of conversion wave energy to hydraulic energy was analyzed. The experimental results show that for a certain device the maximum flow rate and conversion efficiency could be realized through optimization of wave period. It is also shown that the larger the wave height，the bigger the flow rate and the conversion efficiency. The bigger the load pressure，the smaller the flow rate and the conversion efficiency could achieve the maximum when the load pressure was optimal. |
