随着城市建设的不断发展,出现大量高层和次高层建筑,由于自来水管网压力的局限,这些建筑的供水就涉及到二次增压供水的问题。目前二次增压供水方式有许多种,本文就目前的高层和次高层的供水方式进行归纳分析。 With the continuous development of urban construction, a large number of high-rise and sub-high-rise buildings appear. Due to the pressure of the water pipe network, the water supply of these buildings involves the issue of secondary pressurized water supply. At present, there are many kinds of secondary pressurized water supply ways, and the present paper summarizes the current water supply ways of upper and lower levels.
