1·As there isn't much change room for head and motor efficiency, we have to take measures to increase pump efficiency and brine salinity to decrease the electricity consumption for brine extraction.

而扬程和电机的效率均无多大变化空间，要使采卤电耗较低可从提高泵的效率和卤水的含盐量方面来想办法。

2·A set of absorption heat pump is designed to recycle these heat for preheating brine and reduce the steam consumption.

本文的目的是设计一套吸收式热泵回收这部分热量，用来预热盐水，达到降低蒸汽消耗的目的。
