随着城市化进程的不断加快,城市附近河流污染日益严重,不适合作为城市水源地。因此长距离输水工程越来越多,长距离输水水锤防护成为重中之重。其中很少一部分可以利用地形条件进行重力输水,大部分需要加压输水。本文以宁夏某煤矿输水工程为例,主要对比作用相似的两种水锤防护装置:气压罐与箱式双向调压塔,在停泵水锤防护方面的效果,以便今后的工程中进行合理选用。
With the accelerating process of urbanization, river pollution near the city is increasingly serious, not suitable as a city water source. Therefore, more and more long-distance water projects, long-distance water hammer protection has become the top priority. Few of them can use gravity to transport water with topographical conditions and most require pressurized water conveyance. In this paper, a coal mine water diversion project in Ningxia as an example, the main contrast between the two types of water hammer protection devices: pressure tank and tank bidirectional pressure regulating tower, the effect of stopping pump water hammer protection for future projects to be reasonable Use.
