摘要
设计阶段水泵选配不合理会造成变频二次供水机组低效运行,设计秒流量计算结果偏大是影响水泵合理选配的主要因素。课题通过对不同规模和类型居住小区生活用水的实时监测,研究分析了最高日用水定额、时变化系数和户用水人数的取值应考虑的因素,并提出合理的建议,为居住区变频二次供水设计秒流量合理计算提供依据。
The improper selection of pumps in the designed stage will lead to the inefficient operation of secondary water supply with frequency converter unit. The main factors affecting rational selection of pumps are the large calculated data of design flow in a residential area. In this study, based on the real-time monitoring of domestic water use in residential areas with different scales and types, the factors taken into account of the maximum daily water use quota, the time variation coefficient and the number of household water users were analysed and the reasonable suggestions were given,provide basis for reasonable calculation of second flow in secondary water supply design.
