Water pump pressure control 50 60hz 220V wholesale automatic pump control

  Water pump pressure control, 50/60hz 220V wholesale automatic pump control

1. Include 3 units main pumps & one unit small pump, it has multiple controlling mode and meets all kinds of complex requests of water supply.

2. Timing change pump function, balance all kinds of  pumps' working time .  improve the average life of the pumps.

3. Up to 8 periods pressure control, and each period can be set any pressure setting control .and realize the timer  ON/OFF function .

4.Sleep function and auxiliary small pump function, save energy and reduce consumption , extend machine’s life.

5. Positive and negative feedback function , can be used for water supply, but also can be used to pump water and  maintain the water level.

6.Over-pressure, low water level, sensor disconnection, inverter failure and  alarm control functions ect.

7.Feedback can connect with  passive remote pressure gauge, active voltage and current transmitter.

8. Feedback device power 0-24V can be modified, stronger commonality.

9. Feedback signals can be selected .it  is more convenient to connect with outer .

10. Standard 0-10V voltage output, can also be arbitrarily modified to other voltage values, the application will be  more flexible.

11.when the inverter get failure,The controller can choose the automatic transfer to the working frequency running  (pressure range control)

12 .Relay fault output function can be selected.

13. Strong adaptable, applicable to various brands frequency  inverter at home and abroad.

14.All digital signal use photoelectric isolation, strong interference ability .

15.With complete key function.

For the setting method of the controller, Please see page 6 and 7 of the manual. The working mode is shown in the following parameter settings:

For example:Meter range is 1.6Mpa, users request is set to 1Mpa constant pressure, the controller will start if pressure <0.6Mpa.

1. One inverter run with one motor,The parameters are set as follows:

  The setting pressure :             F000=1.00

  over-pressure alarm pressure:       F004=1.30

  Meter range:                    F012=1.60

  Sleep frequency:                 F029=30.0

  Wake-up pressure width:F031=0.40 <(F000-F031=0.60this pressure wake up,it will start the  inverter.

  Pump 2 property:          F042=0

  Pump 3 property:          F043=0  

2. One Inverter run with two motors . parameter are set as below:

  The setting pressure :           F000=1.00

  Over-pressure alarm pressure:       F004=1.30

  Meter range:             F012=1.60

  Increase pump pressure threshold width:

 F022=0.05 <(F000-F022=0.95Mpa)the pressure wake up,

and frequency up to 50HZ, to add pump after deferring

  Reduce pump frequency:           F025=35.0

  Sleep frequency:           F029=30.0

Wake-up pressure width: F031=0.40 <(F000-F031=0.60)the pressure wake up .start the inverter .

  Pump 3 property:          F042=0

3. One Inverter run with three motors . parameter are set as below:

  The setting pressure:           F000=1.00

  Over-pressure alarm pressure:       F004=1.30

   Meter range:                    F012=1.60

  Increasing pump pressure threshold width:

F022=0.05 <(F000-F022=0.95Mpa) the pressure wake up, and frequency

up to 50HZ, to add pump after deferring.

  Reduce pump frequency:           F025=35.0

  Sleep frequency:           F029=30.0

Wake-up pressure width:  F031=0.40  <(F000-F031=0.60)less than awaking .Run VFD.

Small Pump setting as below:

With auxiliary pump:

Small pump starting pressure width:   F034=0.08     equal (F000-F034=0.92), sleep status,small pump  will start if less than the pressure .  

Small pump stop pressure width:   F035=0.05     equal(F000+F035=1.05),at sleep status,small pump will stop if bigger than the pressure.

Without auxiliary pump:

F033=0;(also can remain and do not change )
