Since the long-term use of secondary pressure booster pump station pumps from the clear water tank to uptake water has many short-comings,so we use a reliable non-negative pressure water-supply equipment to replace the traditional model of high lift pump and clean water tank,after the transformation of the system is able to control its pressure and flow,constant pressure water supply can be achieved with the pur-pose of saving energy. In the meanwhile,water hammer,air and other issues has improved. Thus,optimizing the water pressure station.%鉴于加压泵站长期采用水泵从清水池吸水二次加压方式存在诸多弊端，采用了性能可靠的无负压设备取代传统模式的高扬程水泵和清水池，改造后的系统能够有效控制其压力和流量，实现恒压供水，而且节能，并对水锤、空气等问题有所改进，优化了加压站的供水系统。
