When level value, during higher than the target setting value, the source pump power reduces, decreased influent flow, and lower than the target setting value, the source pump power increases, and inflow increases.
When force value, higher than the target setting value, conveying pump power reduces, and pushing quantity reduces, lower than the target setting value, and the conveying pump increased power, pushing quantity increases.
When turbidity value higher than the target setting value, the dosing pump increased power, chemical feeding quantity increases, lower than the target setting value, dosing pump power reduces, chemical feeding quantity reduces.
When chlorine content, higher than the target setting value, the chlorination spinning pump power reduces, and reduces chlorine dosage, and lower than the target setting value, chlorine dosage increases.
Embodiment 2
Described frequency-variable controller can be connected electrically in and calculate on display unit, calculate display unit can with field device communicating, carry out data capture, analyze, controlled the operation of each equipment with optimized scheme, and carry out the data storage, and in order to carry out the equipment operation in the future, optimize and fault inquiry, realize full-automatic.
