Preferably, when the liquid level pace of change in the buffer pool is positive value, the liquid level in the buffer pool is higher than second
When liquid level when setting liquid level and in the cooling tower sets liquid level lower than described first, the control system is sent out to pump group
Increase pump instruction out or increase frequency and instruct, the control system opens the overflow valve on buffer pool simultaneously.
Preferably, when the liquid level of the buffer pool is more than specified level value, sewage overflow in the buffer pool to the
Two buffer pools.
Preferably, the control system also monitors the actual flow of each elevator pump in the pump group, and more each elevator pump
Default flow and actual flow difference, when the control system sending subtract pump instruction when, preferentially close the difference
Maximum elevator pump.
Compared with prior art, detailed description are as follows by the application:
The control system is compared according to the liquid level variation in buffer pool and the level value in cooling tower, and passes through ratio
Relatively result judges the pump discharge of pump group, has the advantages that adjustment is flexible, saves manpower, and has calculating, operation timely excellent
Point.
The buffer pool is also in series with the second buffer pool, when the sewage in buffer pool is more than in specified liquid level or cooling tower
When residual capacity is not enough to the sewage increment in equalizing and buffering pond, control system opens overflow valve, makes sewage overflow in buffer pool
To the second buffer pool, have the advantages that avoid cooling tower or pump group overload operation.
Due to containing impurity in the sewage of elevator pump pumping, after promoting pump operation to a period of time, the miscellaneous of interior deposition is pumped
Matter influences the actual flow of elevator pump, therefore the control system also monitors the actual flow of each elevator pump in the pump group, and
Compare the default flow of each elevator pump and the difference of actual flow, when control system sending subtracts pump instruction, preferentially
The maximum elevator pump of the difference is closed, worker can clean and decontaminate to the elevator pump after closing, prevent elevator pump from blocking
Equipment fault is caused, the working efficiency of pump group is influenced.
