一、概述
JY-WFY型无负压供水设备充分利用了自来水管网的原有压力，在原有压力的基础上实现压力又叠加，实现差多少，补多少，使二次加压设备的选型减小，节省投资，同时无负压供水设备在使用过程中也可大大节能，是目前最先进最新型的二次供水方式。
二、设备特点
1、高效节能：无负压供水设备能根据用户的实际用水量和使用压力自动检测，调节电动机的转速(耗电量)，使设备始终处于高效率的工作状态。
2、供水管网压力稳定：无负压供水设备由微机构成自动闭环控制，能在0.5秒内使变化的压力恢复正常，压力调节精度为设定值的±5% .
3、占地小、投资少，安装工期短：无负压供水设备与其他老式供水设备相比节约占地3~16倍，比建水塔节约节约投资15%~60%。体积小，组装、安装调试方便，运输及安装工期短。
4、保护功能全，运行安全可靠，操作方便：无负压供水设备主机采用进口变频调速器，自身具有欠压、过压、过载、短路、过热、失速防止等保护功能，无故障运用达10万小时以上。无负压供水设备配电控制部分，采用智能化控制原理，操作方便实用，设备工作状况一目了然。便于非专业人员很快熟练掌握。
5、供水功能全，保险系数高：无负压供水设备局部出现故障时，能启用应急功能继续供水。可与市政供水网自动并网运行，并具有双恒压功能，即能满足生活生产用水的正常压力和流量，能在出现火情时自动转换为高压大流量供水，可一机多用。
三、应用领域
无负压供水设备的管网增压设备适用于自来水压不足的高层建筑、居民小区、别墅等居民生活用水。企事业单位、宾馆、写字楼、百货商场，大型桑拿浴、医院、学校，体育馆，高尔夫球场，机场等场所的日常用水需要二次增压供水的场合。生产制造、洗涤装置、食品工业、工厂、工矿的生产用水。老旧水池供水及其它形式供水的改造。各种水源给水中间加压泵站；各种加压循环系统。
四、工作原理
无负压供水设备通过微机设定用户所需的供水压力，当用户的用水量增加，微机检测到自来水的压力低于用户所需的用水压力时，微机会自动控制变频器启动，管网压力调节系统工作，直到使管网压力增加到用户所需的用水压力时，微机控制变频器输出一恒定 的频率，管网压力调节系统以一恒定的压力运行，保证用户用水压力恒定。
当用户的用水量减少，自来水的压力逐渐恢复到用户所需的用水压力，微机控制变频器输出的频率逐渐降低直至增压泵停止运行，系统充分利用了自来水原有的压力，又保证了用户供水压力的稳定。
