Load operation, the rotation of motor can bring 100 DEG C or so of high temperature, have a strong impact on information transmission, and CAN can be avoided effectively
This problem；Meanwhile variable frequency pump can effectively control water-carrying capacity, so as to saving water resource, during the water use peak phase, opening needs
Variable frequency pump, when night or water demand are few, only open low discharge variable frequency pump.
Further, the full frequency conversion supply water system of above-mentioned intelligence, in addition to flow regulator, the flow regulator are set
Between the tap water pipe network and user's pipe network, the CAN branch line electrically connects with flow regulator, the Flow-rate adjustment
Device is used for preliminary water-carrying capacity and controlled.
Further, the flow regulator includes negative pressure canceller and fluid level controller, the negative pressure canceller and liquid level
Controller is all disposed within inside flow regulator, and is electrically connected with CAN branch line, and negative pressure canceller eliminates negative in water pipe
Pressure, fluid level controller are used to control liquid level.
Further, at least provided with 3 variable frequency pumps and 1 low discharge variable frequency pump in the water pump group.
Further, the full frequency conversion supply water system of above-mentioned intelligence, in addition to valve, check-valves, the valve are arranged on institute
State the current input of the current output end of tap water pipe network, variable frequency pump and low discharge variable frequency pump；The check-valves is set
In the current output end of the current output end and user's pipe network of variable frequency pump and low discharge variable frequency pump.
Further, in addition to pressure sensor, the pressure sensor are arranged on current input or the output end of user's pipe network, and institute
State pressure sensor to electrically connect with the CAN branch line, the pressure sensor is fed back due to big hydraulic pressure size in detection service pipe
To computer.
