[具体实施方式][Detailed ways]

下面结合附图和实施例对本实用新型作进一步详细说明。Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

如图1，一般供水时段自来水由市政管网进水口1通过电磁阀2经过无负压罐3到水泵8的进水口，由变频控制柜4根据压力传感器9的压力信号恒压变频供水，这种供水方式叠加了市政管网原有压力，达到节能效果，比如市政水压是30米，用户管网需要压力是50米，水泵只需消耗20米的能耗，节电60％，还可避免水的二次污染。As shown in Figure 1, during the general water supply period, the tap water is supplied from the municipal pipe network water inlet 1 through the solenoid valve 2 through the non-negative pressure tank 3 to the water inlet of the water pump 8, and is supplied by the frequency conversion control cabinet 4 with constant pressure and frequency conversion according to the pressure signal of the pressure sensor 9. This water supply method superimposes the original pressure of the municipal pipe network to achieve energy-saving effects. For example, the municipal water pressure is 30 meters, and the pressure required by the user pipe network is 50 meters. The water pump only consumes 20 meters of energy consumption, saving 60% of electricity, and can Avoid secondary pollution of water.

变频控制柜4可自由设定用水高峰时段，在高峰时段变频控制柜4关闭电磁阀2，自来水通过浮球阀5自流到水池12，水通过进水控制器13到水泵的进水口，由变频控制柜4根据压力传感器9的压力信号恒压变频供水，如果电接点压力表10检测到市政压力低于设定压力也会自动切换到这种供水模式，调节用水高峰，提高了现有管网的利用率。The frequency conversion control cabinet 4 can freely set the peak time of water consumption. During the peak time, the frequency conversion control cabinet 4 closes the solenoid valve 2, the tap water flows to the pool 12 through the float valve 5, and the water passes through the water inlet controller 13 to the water inlet of the water pump, controlled by frequency conversion The cabinet 4 supplies water with constant pressure and frequency conversion according to the pressure signal of the pressure sensor 9. If the electric contact pressure gauge 10 detects that the municipal pressure is lower than the set pressure, it will automatically switch to this water supply mode to adjust the peak water consumption and improve the efficiency of the existing pipe network. utilization rate.

还可以实现增加一个备用水源的目的，水池12可以根据需求建成足够大的水池或水箱，在市政停水的时候，自动切换到从水池或水箱抽水的模式。The purpose of adding a backup water source can also be realized, and the pool 12 can be built into a large enough pool or a water tank according to the demand, and when the municipal water is cut off, it will automatically switch to the mode of pumping water from the pool or the water tank.

在增压泵站停电的情况下，自来水由市政管网进水口1通过电磁阀2经过无负压罐3通过旁通管6向用户管网14自压供水，本市政管网节能增压设备可应用于新建，也可应用于原有水池节能改造。In the event of a power outage at the booster pump station, the tap water is self-pressurized from the municipal pipe network water inlet 1 through the solenoid valve 2 through the non-negative pressure tank 3 and through the bypass pipe 6 to the user pipe network 14. This energy-saving booster equipment for the municipal pipe network It can be applied to new construction as well as energy-saving renovation of existing pools.
