The mode of operation of I and II pump house intelligent water supply system
There are following three kinds of mode of operations:
A: Pressure Unit supplies water
When switch board receives H
41and H
2signal, if H
2economic pressures H can not be met
41time, switch board sends to water pump assembly and starts water pump and open electric butterfly valve instruction, by the PID control technology in PLC, adopts staged variable-frequency variable-voltage technology to regulate the running frequency of water pump, realizes minimum requirements pressure H
42requirement; Described staged variable-frequency variable-voltage technology refers to that segmentation divides the time to set PID desired value, makes the running frequency staged of water pump increase, until meet H
42requirement; Wherein,
H
2for the discharge pressure of repumping house intelligent water supply system water pump assembly;

2time, switch board sends to water pump assembly and starts water pump and open electric butterfly valve instruction, by the PID control technology in PLC, adopts staged variable-frequency variable-voltage technology to regulate the running frequency of water pump, until H
2equal constant voltage value, realize constant pressure water supply; When constant voltage value is less than H
2time, switch board, by the PID control technology in PLC, adopts the running frequency that staged variable-frequency variable-voltage technology regulates water pump, until H
2equal constant voltage value, realize constant pressure water supply;
Two, the mode of operation of pressurizing point intelligence control system
There are following three kinds of mode of operations;
A:: bypass circulation directly supplies water
When switch board receives H
3and H
41signal, works as H
3h can be met
41time, switch board sends OPEN to the electric butterfly valve in pipeline loop, to water pump and the electric butterfly valve transmission out code of water pump assembly, is directly supplied water to pipeline by bypass circulation Non-energy-consumption;
B: Pressure Unit supplies water
When switch board receives H
3and H
41signal, if H
3economic pressures H can not be met
41time, switch board sends to water pump assembly and starts water pump and open electric butterfly valve instruction, by the PID control technology in PLC, adopts staged variable-frequency variable-voltage technology to regulate the running frequency of water pump, realizes minimum requirements pressure H
42requirement;
C: time delay is supplied water
Work as H
3h can not be met
42, server sends early warning signal, notifies that staff finds out pipe network operation situation, if any exception, needs termination of pumping process; As without exception, switch board sends to water pump assembly and starts water pump and open electric butterfly valve instruction, by the PID control technology in PLC, adopts staged variable-frequency variable-voltage technology to regulate the running frequency of water pump, realizes minimum requirements pressure H
42requirement; Wherein,
H
