水泵与水箱联合供水系统水箱储备水量极限值分析

An Analysis of the Limit Value About the Reserve Water in Supplying Water by Both the Water Tank and the Water Pump

通过对水泵和水箱联和供水系统中水箱运行状况的分析，提出水箱有效容积应分为水箱调节水量和储备水量两个部分。对储备水量的极限值进行分析，给出了水箱有效容积的计算公式。

This paper puts forward that the useful volume of the water tank should be both the amount of the adjusted water and the amount of the reserve water,through analyzing running condition in the supplying water system by both the water tank and the water pump. And it has an analysis of the limit value about the reserve water. Besides, it also shows the calculating formula of the water tanks useful volume.
