Specific embodiment
Embodiment
A kind of water treatment system of frequency control, as depicted in figs. 1 and 2, including whirling well 1, filter 2, cooling bay 3,
High-pressure hydraulic pump 4 with frequency converter, pipeline 5 and frequency changing regulating speed control apparatus 6；The frequency changing regulating speed control apparatus 6 includes pressure
Force snesor 8, flow sensor 9, the PLC10 equipped with PID control component；
It is connected between the whirling well 1, filter 2, cooling bay 3 and high-pressure hydraulic pump 4 with frequency converter by pipeline 5,
The frequency changing regulating speed control apparatus 6 is connect with the frequency converter 7 of pipeline 5 and high-pressure hydraulic pump respectively；The pressure sensor 8 and flow
Sensor 9 is connect with PLC10 respectively；The pressure sensor 8 and flow sensor 9 are respectively arranged at whirling well 1, filter 2,
In pipeline 5 between cooling bay 3 and high-pressure hydraulic pump 4 with frequency converter.
PLC type number in the present embodiment is S7-300, frequency converter model 6SE70.
The design principle of the utility model is：Frequency converter using the PLC10 equipped with PID control component as high-pressure hydraulic pump
7 controller, when pressure, flow are lower than setting value in practical water supply line, PLC increases to the speed preset of frequency converter, directly
It is more than or equal to pressure set points to practical line pressure, flow, conversely, PLC gives when line pressure, flow are greater than the set value
The speed preset of frequency converter declines, and is decreased until the pressure in pipeline, flow less than or equal to setting value.Continuously adjusting state
