用户用水的多少是经常变动的，因此给水不足或给水过剩的情况时有发生。而用水和给水之间的不平衡集中反映在给水的压力上，即用水多而给水少，则压力低；用水少而给水多，则压力大。保持给水压力的恒定，可使给水和用水之间保持平衡，即用水多时给水也多，用水少时给水也少，从而提高了给水的质量。——奥凯二次供水设备
The number of water users is constantly changing, so the water supply shortage or excess water occurs from time to time. And between water and the water reflects the imbalance in the water supply pressure, namely water and water supply is less, low pressure; less water and water supply, the pressure. To maintain a constant water supply pressure, can make a balance between water supply and water, is also much less water when the water for a long time water supply, water supply is less, so as to improve the water quality.
随着城市化进程的不断扩张，高层建筑与日俱增，供水成了城市生活的一大焦点。原有的市政网管一次供水对于多层住宅可能具有比较好的效果，但在高层和小高层建筑面前却显得力不从心。早期通过气压、变频等方法对高层建筑进行二次加压供水来改变城市供水现状，这种传统的二次供水方法由于水池、水箱诸多中间构件的形成，不利于节能且对水资源容易造成二次污染。技术的日新月异，无负压供水设备随之诞生。在其发展至今的十多年时间，无负压供水这种新型的二次供水方式因为其良好的节地、节能、***性能，被现代高层建筑供水体系广泛的应用。——【奥凯环保科技有限公司】
