Cabinet 7 is PLC control cabinet.
The utility model protects the present apparatus by pressure sensor PS13, Intelligent control cabinet 7 and variable frequency pump 6, when just
Often during work, after the soft start of variable frequency pump 6, pressurization is supplied water, when pressure sensor PS13 detects that outlet pressure reaches setting pressure
During the upper limit of power, at this moment Intelligent control cabinet 7 sends signal to variable frequency pump, the frequency conversion frequency reducing of variable frequency pump 6, until low frequency sleep,
Ensure that outlet pressure is stable, when outlet pressure sensor PS13, which is detected, is down to setting low pressure limit, Intelligent control cabinet 7 is to change
Frequency water pump 6 sends signal, and variable frequency pump 6 automatically resets, and then after the soft start of variable frequency pump 6, pressurization is supplied water, the whole pressurization made
Keep outlet pressure stable in water supply process.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
