Often with no negative pressure technology in city water supply, non negative pressure water supply equipment is a municipal pipe network for water, make full use of the original pressure of municipal pipe network, forming a continuous relay supercharging water supply way closed. 生活用水的特點(diǎn)是使用時(shí)間集中，夜間使用量接近于零。為了減少給水設(shè)備小流量或零流量時(shí)水泵的能耗，生活變頻供水設(shè)備一定要配置穩(wěn)壓氣壓罐，在小流量或零流量供水時(shí)，由氣壓罐穩(wěn)壓補(bǔ)充。因?yàn)闅鈮汗奘撬媚軌蜻M(jìn)入睡眠的前提條件氣壓罐體積決議了在一定壓力范圍內(nèi)補(bǔ)充管網(wǎng)的水量；在管網(wǎng)泄露流量(L/S)一定的狀況下，氣壓罐的體積大小決議了水泵再啟動間息時(shí)間的長短，體積越大，間息時(shí)間越長；因而，選擇體積稍大的氣壓罐可延長水泵的睡眠時(shí)間。關(guān)于生活變頻供水設(shè)備
