/></p><p>2、当用户的用水量增加导致市政水管网与稳流罐连接处的压力下降的时候，稳流罐中形成负压，真空抑制器开始工作将进气阀打开，空气进去到稳流罐中。这时候稳流罐相当于一个有自由液面的开口水箱，其压力跟大气相同，这样负压就被消除了。水位下降到设定值时，液位控制器将控制信号传递给变频控制柜中的控制系统，控制加压机组停止工作，用户停水；当用户用水量减小时，稳流罐中水位上升，气体从真空抑制器排气阀门排除，压力恢复正常后，加压机组重新自动启动，恢复供水。</p><p>3、当市政管网停水的时候，加压机组在也为控制器的控制下自动停止运行，市政管网开供水恢复之后，自顶气动重新恢复正常的供水。</p><p>4、当用户不用水或者用水量很小的时候，无负压供水设备就会进入到自动?；刺?，并且保持供水压力。当压力加大用水量增多之后恢复正常的供水。</p><p>5、停电供水原理：当小区停电之后市政管网会继续为用户供水，停电而不停水，恢复供电之后，设备自动启动恢复正常的供水。</p><h3>设备图片：</h3><p><img
