随着我国高层建筑越来越多；城市人口急剧增加，且城镇小区化建设的普及致使自来水管网压力出现不足，很多城市普遍存在着用水高峰期生活用水上不去水的现象。由此引起生活、办公用水难的问题。 目前，普遍采用的办法是修建高位水池(箱)或者地下式蓄水池(箱)，通过水泵二次加压供水。但是采用这种方式，不仅设备投资大，而且由于采用二次供水，水质容易受到污染。在自然条件下水池中容易生成一些细菌、藻类、微生物等，使水质受到污染，水箱需要定期消毒清理，由此会产生临时停水、增加设备的使用成本。 QBWS-W/L系列供水设备是我公司创新研制开发的无负压管网增压设备。该设备全封闭设计，可直接与自来水管网连接，通过自动补气装置和流量调节器保护自来水管网不形成负压，保证了自来水管网稳压(无负压)、安全、卫生的向用户供水，避免了修建混凝土蓄水池或设水箱的麻烦。该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、卫生无污染 设备为全密封运行，异物不能进入管网系统；不与空气直接接触，自动补气装置的膜滤装置将空气中的细菌挡住，不会进入系统；流量调节器采用全不锈钢制造，不会滋生藻类，真正达到不污染水源，满足人们对饮用水越来越高的要求。2、不浪费能源 管网增压供水设备直接与自来水管网连接，在原有管网压力的基础上叠加所需的压力差，差多少，补多少，能充分利用管网的余压，不会造成设备和能源的浪费，符合国家节能的要求。3、设备管理方便、简单 直接式管网增压供水设备为智能控制全自动运行，设备停电停水自动停机，来电来水自动开机；由于全封闭设计，不会产生污染，因此无需麻烦的清洗工作。符合环保要求。4、投资少、运行成本低 因为无需修建蓄水池或水箱，所以节省了一大笔土建投资，而且由于利用了自来水管网的余压，无需从零加压，因此，加压泵选型较小，设备投资减少。 由于加压泵的选型较小，而且采用多泵并联运行，在用水低峰期一台泵即可满足用水需要，用水高峰时才会启动其它泵，因此，设备运行过程中能耗非常低，降低了运行成本。5、安装简单 直接式管网增压供水设备成套供应用户，现场只需将设备组装起来，连接进、出水管法兰即可，施工周期短，安装简单。6、占地面积小因为不需要建水池或水箱，大大节约了占地面积，根据用户的现场情况可设计成立式或卧式不同的安装方式，检修方便。7、停电可维持供水由于设备有一条公共供水管路与用户管网直接相通，在停电时加压泵虽停止工作，但低区用户依旧可维持用水，即使在停水时，用户依旧可以靠稳压平衡器的存水维持短时间供水。8、自动化程度高采用PID闭环调节，恒压精度高，水压波动小。具有过载、短路、过流等各种自动保护功能，设备运行稳定、可靠，方便使用和维护。三、应用领域管网增压设备适用于自来水压力不足的居民区、工厂、医院、机关、写字楼等需要二次增压供水的场合；各种水源给水中间加压泵站；各种加压循环系统等。四、系统简图1.负压表2.真空抑制器3.过滤器4.流量调节器5.倒流防止器6.压力传感器7.旁通管路8.泵进口阀门9.旁通管路止回阀10.水泵11.旁通管路阀门12.泵出口止回阀13.泵出口阀门14.压力传感器15.变频电控柜16.超压保护装置17.小流量保压管18.清洗排污阀五、工作原理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。 当微机检测到流量调节器内压力低于一个大气压时，自动补气装置开始工作，来稳定流量调节器和自来水的进水压力使系统内不产生负压，从而保证自来水管网和管网压力调节系统正常工作，用户用水不会产生压力不足或断流现象。当流量调节器内压力升高时，自动补气装置又可将多余的气体排出流量调节器外，使流量调节器内储满水，以备下次用水高峰时使用；当流量调节器内储满水后，自动补气装置自动关闭，防止溢流。六、技术参数与适用范围1.流量范围：0-600m3/h2.压力范围：0-2.5Mpa3.配备功率：132Kw4.压力调节精度：0.01Mpa5.环境温度：0-406.相对湿度：90(电控系统)7.电源：三相,380V(10)，50Hz2Hz8.流量调节器容积：0.31m3-2.4m3七、产品型号说明八、性能参数表系列一设备型号WWG流量m3/h扬程m参考户数推荐水泵推荐调节罐电控柜型号型号功率Kw台数规格容积m32.4-40-22.4403CDL1-900.552600*12000.31SFB-0.75/22.4-48-248CDL1-1000.55SFB-1.5/22.4-56-256CDL1-1200.75SFB-1.5/22.4-64-264CDL1-1300.75SFB-1.5/22.4-72-272CDL1-1500.75SFB-1.5/22.4-80-280CDL1-1701.1SFB-1.5/22.4-88-288CDL1-1901.1SFB-1.5/22.4-96-296CDL1-2101.1SFB-2.2/22.4-104-2104CDL1-2301.1SFB-2.2/22.4-112-2112CDL1-2501.5SFB-2.2/22.4-120-2120CDL1-2701.5SFB-2.2/26-40-26408CDL3-900.75SFB-1.1/26-50-250CDL3-1101.1SFB-1.5/26-60-260CDL3-1301.1SFB-2.2/26-70-270CDL3-1501.1SFB-2.2/26-80-280CDL3-1701.5SFB-2.2/26-90-290CDL3-1901.5SFB-2.2/26-100-2100CDL3-2102.2SFB-3/26-110-2110CDL3-2502.2SFB-3/26-120-2120CDL3-2702.2SFB-4/210-30-2103020CDL4-701.5SFB-1.5/210-45-245CDL4-1002.2SFB-2.2/210-60-260CDL4-1202.2SFB-3/210-75-275CDL4-1603SFB-4/210-90-290CDL4-1904SFB-4/210-105-2105CDL4-1204SFB-5.5/210-120-2120CDL8-1204SFB-5.5/213-30-2133030CDL4-701.5800*15000.68SFB-1.5/213-45-245CDL4-1002.2SFB-2.2/213-60-260CDL4-1202.2SFB-3/213-75-275CDL4-1603SFB-4/213-90-290CDL4-1904SFB-4/213-105-2105CDL4-1204SFB-5.5/213-120-2120CDL8-1204SFB-5.5/216-30-2163040CDL4-701.5SFB-1.5/216-45-245CDL4-1002.2SFB-2.2/216-60-260CDL4-1202.2SFB-3/2系列一设备型号WWG流量m3/h扬程m参考户数推荐水泵推荐调节罐电控柜型号型号功率Kw台数规格容积m316-75-2167540CDL4-16032800*15000.68SFB-4/216-90-290CDL4-1904SFB-4/216-105-2105CDL4-1204SFB-5.5/216-120-2120CDL8-1204SFB-5.5/219-30-2193055CDL8-502.2SFB-2.2/219-45-245CDL8-803SFB-3/219-60-260CDL8-1004SFB-4/219-75-275CDL8-1204SFB-5.5/219-90-290CDL8-1405.5SFB-5.5/219-105-2105CDL8-1605.5SFB-7.5/219-120-2120CDL8-1807.5SFB-7.5/224-30-22430100CDL8-502.2SFB-2.2/224-45-245CDL8-803SFB-3/224-60-260CDL8-1004SFB-4/224-75-275CDL8-1204SFB-5.5/224-90-290CDL8-1405.5SFB-5.5/224-105-2105CDL8-1605.5SFB-7.5/224-120-2120CDL8-1807.5SFB-7.5/230-30-23030150CDL8-502.2SFB-2.2/230-45-245CDL8-803SFB-3/230-60-260CDL8-1004SFB-4/230-75-275CDL8-1204SFB-5.5/230-90-290CDL8-1405.5SFB-5.5/230-105-2105CDL8-1605.5SFB-7.5/230-120-2120CDL8-1807.5SFB-7.5/248-40-24840350CDL32-30-25.5SFB-5.5/248-60-260CDL32-40-27.5SFB-7.5/248-80-280CDL32-5011SFB-11/248-100-2100CDL32-6011SFB-11/248-120-2120CDL32-80-215SFB-15/260-32-26032500CDL32-30-25.51000*18001.28SFB-5.5/260-48-248CDL32-40-27.5SFB-7.5/260-64-264CDL32-5011SFB-11/260-80-280CDL32-6011SFB-15/260-96-296CDL32-7015SFB-15/260-112-2112CDL32-90-218.5SFB-18.5/260-128-2128CDL32-100-218.5SFB-22/2系列一设备型号WWG流量m3/h扬程m参考户数推荐水泵推荐调节罐电控柜型号型号功率Kw台数规格容积m372-40-27240650CDL32-40-27.521000*18001.28SFB-15/272-60-260CDL32-5011SFB-22/272-80-280CDL32-70-215SFB-30/272-100-2100CDL32-90-218.5SFB-37/272-120-2120CDL32-10018.5SFB-45/2100-40-2100401000CDL42-30-2111000*20001.44SFB-11/2100-60-260CDL42-40-215SFB-15/2100-80-280CDL42-50-218.5SFB-18.5/2100-100-2100CDL42-60-222SFB-22/2100-120-2120CDL42-7030SFB-30/2120-40-2120401200CDL42-30-211SFB-11/2120-60-260CDL42-40-215SFB-15/2120-80-280CDL42-50-218.5SFB-18.5/2120-100-2100CDL42-60-222SFB-22/2120-120-2120CDL42-7030SFB-30/2200-40-2200402200100DL100-20*218.51200*20002.04SFB-18.5/2200-60-260100DL100-20*330SFB-30/2200-80-280100DL100-20*437SFB-37/2200-100-2100100DL100-20*545SFB-45/2200-120-2120100DL100-20*655SFB-55/2200-140-2140100DL100-20*775SFB-75/2300-50-2300503500150DL160-25*237SFB-37/2300-75-275150DL160-25*355SFB-55/2300-100-2100150DL160-25*475SFB-75/2300-125-2125150DL160-25*590SFB-90/2300-150-2150150DL160-25*6110SFB-110/2300-175-2175150DL160-25*7132SFB-132/2系列二设备型号WWG流量m3/h扬程m参考户数推荐水泵推荐调节罐电控柜型号型号功率Kw台数规格容积m33.6-40-33.6405CDL1-900.553600*12000.31SFB-0.75/33.6-48-348CDL1-1000.55SFB-1.5/33.6-56-356CDL1-1200.75SFB-1.5/33.6-64-364CDL1-1300.75SFB-1.5/33.6-72-372CDL1-1500.75SFB-1.5/33.6-80-380CDL1-1701.1SFB-1.5/33.6-88-388CDL1-1901.1SFB-1.5/33.6-96-396CDL1-2101.1SFB-2.2/33.6-104-3104CDL1-2301.1SFB-2.2/33.6-112-3112CDL1-2501.5SFB-2.2/33.6-120-3120CDL1-2701.5SFB-2.2/39-40-394015CDL3-900.75SFB-1.1/39-50-350CDL3-1101.1SFB-1.5/39-60-360CDL3-1301.1SFB-2.2/39-70-370CDL3-1501.1SFB-2.2/39-80-380CDL3-1701.5SFB-2.2/39-90-390CDL3-1901.5SFB-2.2/39-100-3100CDL3-2102.2SFB-3/39-110-3110CDL3-2502.2SFB-3/39-120-3120CDL3-2702.2SFB-4/315-30-3153040CDL4-701.5800*15000.68SFB-1.5/315-45-345CDL4-1002.2SFB-2.2/315-60-360CDL4-1202.2SFB-3/315-75-375CDL4-1603SFB-4/315-90-390CDL4-1904SFB-4/315-105-3105CDL4-1204SFB-5.5/315-120-3120CDL8-1204SFB-5.5/319.5-30-319.53075CDL4-701.5SFB-1.5/319.5-45-345CDL4-1002.2SFB-2.2/319.5-60-360CDL4-1202.2SFB-3/319.5-75-375CDL4-1603SFB-4/319.5-90-390CDL4-1904SFB-4/319.5-105-3105CDL4-1204SFB-5.5/319.5-120-3120CDL8-1204SFB-5.5/324-30-32430100CDL4-701.5SFB-1.5/324-45-345CDL4-1002.2SFB-2.2/324-60-360CDL4-1202.2SFB-3/3系列二设备型号WWG流量m3/h扬程m参考户数推荐水泵推荐调节罐电控柜型号型号功率Kw台数规格容积m324-75-32475100CDL4-16033800*15000.68SFB-4/324-90-390CDL4-1904SFB-4/324-105-3105CDL4-1204SFB-5.5/324-120-3120CDL
