应用高位气压水罐改善气压给水设备工况

IMPROVING THE PERFORMANCE OF PRESSURE WATER SUPPLY EQUIPMENT BY HIGH LEVEL PRESSURE TANK

文中分析了气压给水设备工况后认为,气压水罐置于建筑物顶层的供水方式和置于底层的供水方式相比,高位气压水罐供水方式能改善气压给水设备的工况,它既可以节省电耗,减少出水压力变化,又可以增大罐内的贮水容量。文中还简要介绍了专为设置于建筑物顶部而设计制造的“日立蓄压式水罐”的构造、工作原理及设计参数。

Based on the analysis of performance of pressure water supply equip- ments,the article indicates that advantages such as improvement of performance,saving of power,reduction of exit pressure fluctuation and increase of Lank capacity can be obtained if the pressure tank is put on top of the building instead of bottom.The stru cture,principle and design parameters of“Hitachi Pressure Tank”which is especially designed and manufactured for installation on top of buildings are also presented.
