稳流罐  Steady flow tank

无负压控制

系统设定一恒定压力值,如果管网压力高于设定压力值时,压力变送器将管网压力反馈给变频控制柜,自来水可通过直供管路直接到达用户管网对用户进行供水。稳流罐当市政管网压力变化或用户管网用水量变化使管压力低于设定压力时,压力变送器将管网压力反馈给变频控制柜中的PlD控制器,通过PlD控制器调整变频器的输出频率,启动水泵机组并调节水泵转速保持恒压供水;如果不能满足供水要求时,则控制柜将控制多台工频泵的启停和变频泵的转速,从而达到恒压变量供水的要求。


无负压设备采用微机变频技术和有效的负压处理技术实现叠压供水。具体如下:该设备通过稳流罐的真空补偿系统及全封闭结构实现了与自来水管网的直接串接,并且克服了对管网的不良影响。该设备通过管网压力表、真空抑制器及稳流补偿器中的检测装置采集稳流罐内的真空度及水位信号,实时反馈,通过微机控制真空抑制器及稳流补偿器中的特殊装置动作,抑制负压产生,保证稳流罐消除负压该设备不对城市管网产生影响。

Steady flow tank

No negative pressure control

The system sets a constant pressure value, if the pipe network pressure is higher than the set pressure value, the pressure transmitter will feed back the pressure of the pipe network to the frequency conversion control cabinet, and the tap water can directly reach the user pipe network through the direct supply pipe to supply water to the user . Steady flow tank When the municipal pipe network pressure changes or the user pipe network changes in water pressure pipe pressure is lower than the set pressure, the pressure transmitter pressure feedback to the PID control cabinet PID controller, adjusted by the PlD controller Inverter output frequency, start the pump unit and adjust the pump speed to maintain constant pressure water supply; if you can not meet the water requirements, the control cabinet will control multiple frequency pump start and stop and frequency conversion pump speed, so as to achieve constant pressure variable water supply Request.


Negative pressure equipment adopts microcomputer frequency conversion technology and effective negative pressure treatment technology to realize the laminated water supply. The details are as follows: The device realizes the direct connection with the water pipe network through the vacuum compensation system of the steady flow tank and the totally enclosed structure, and overcomes the adverse influence on the pipe network. The device collects the vacuum degree and the water level signal in the steady flow tank through the pressure gauge in the pipe network, the vacuum suppressor and the detecting device in the steady flow compensator, real-time feedbacks, and controls the special devices in the vacuum suppressor and the steady flow compensator by the microcomputer Action to suppress negative pressure to ensure steady flow tank to eliminate negative pressure The device does not affect the urban pipe network.
