结合反渗透海水淡化高压泵的能耗状况，合理选择了万吨级反渗透海水淡化高压泵的泵型，提出了一种轴向吸入节段式高压多级泵的新型结构型式。

Considering the energy consumption of the HP-pump for SWRO, a reasonable type of high pressure pump was selected, and a new structure of the axial suction segment multistage pump was proposed.

另外还在一级反渗透膜处理水出口与二级高压泵进水口之间设置了加碱液装置和中间水箱。

In addition, a lye-feeding device and a middle water tank are arranged between the water outlet of the primary reverse osmosis membrane and the water inlet of the secondary high-pressure pump.
