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.

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。

The article mainly had a research on the pressure rule inside the hydraulic cylinders when the mud pump has been assembled with air chamber on the suction pipe and stack pipe.

但国内还没有对安装吸入空气包后液缸内吸入压力的变化规律作出理论上的分析。

Pump could not suction water. The fingers of pressure gauge and vacuum gauge swing acutely.

水泵不吸水，压力表及真空表的指针在剧烈摆动。
