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.
