    山东电采暖锅炉应用先进的现代控制理论,结合可编程控制技术、变频控制技术、电机泵组控制技术的新型机电一体化供水装置。 无负压供水设备使用时为什么不会对管网产生负压,是应用了一定的技术理论才成为了如今的无负压供水设备。

    Shandong electric heating boiler applies advanced modern control theory, combined with programmable control technology, frequency conversion control technology, motor pump group control technology of new electromechanical integrated water supply device. When no negative pressure water supply equipment is used, why can't it produce negative pressure to the pipe network? It is the application of certain technical theory that has become the present non negative pressure water supply equipment.

    供水设备供水采用多泵并联的供水方式,用户用水量的大小决定了投入运行的水泵的数量,当用水量较小时,单台泵变频工作,当用水量增加.

    The water supply of water supply equipment adopts multi pump parallel water supply mode. The amount of water used by the user determines the number of pumps to be put into operation. When the water consumption is small, the frequency of the single pump will be increased, and the water consumption will increase

    变频调速供水设备通过安装在水泵出水总管上的远传压力表,将出口压力转换成0-5V电压信号,经A/D转换模块将模拟电压信号转换成数字量并送入可编程序控制器,经可编程内部PID运算,得出一调节参量并将该参量送入D/A转换模块,经数摸转换后将得出模拟量传送变频器,进而控制其输出频率的变化。

    Frequency of water supply equipment through remote pressure gauge installed on the pump outlet pipe, outlet pressure will be converted into 0-5V voltage signal, the analog voltage signal into digital signal and sent to the programmable controller A/D conversion module, the programmable internal PID operation, the adjustable parameters and the parameters to the D/A conversion module. After a few touch conversion will come to analog transmission frequency, change the output frequency and control.

    水泵运行频率随之增加,如达到水泵额定输出功率仍无法满足用户供水要求时,该泵自动转换成工频运行状态,并变频启动下一台水泵。

    The running frequency of the water pump is increased, and when the rated output power of the water pump can not meet the requirements of the user for water supply, the pump is automatically converted into the running state of frequency power, and the starting pump is started by frequency conversion.

    反之,当用水量减少,则降低水泵运行频率直至设定下限运行频率,如供水量仍大于用水量,则自动停止工频运行泵同时变频泵转速增加。

    On the contrary, when the water consumption is reduced, the running frequency of the water pump is lowered until the lower limit running frequency is set; if the water supply quantity is still larger than the water consumption, the power frequency running pump is automatically stopped, and the speed of the frequency conversion pump is increased at the same time.

    当用水量降至某一程度时(如夜间用水很少时),变频主泵停止工作,改由辅泵及小型气压罐供水。

    When the water drops to a certain extent (such as water, little night) inverter pump stops working, by the auxiliary pump and small pressure water tank.
