Irrigation variable frequency controller-Pump controller



Product Introduction

Irrigation variable frequency controller is a good assistant to realize intelligent irrigation in agriculture.
In the smart irrigation solution, the smart irrigation frequency conversion controller can be used with the water pump to control the pump to adjust the pressure, flow rate control, etc.

Irrigation frequency conversion controller can also be used in combination with water and fertilizer integrated machine, which can realize water-saving irrigation and fertilization. It can also be customized according to actual needs.

Irrigation variable frequency controller Features

① The core control component is equipped with microprocessor and high-power transistor, which has powerful function and long service life.

② Word PID adjustment, keyboard operation, digital display, automatic operation unattended.

③ Programmable controller for programming control. Flexible control mode, stable and reliable work.

(4) No loss pump motor speed adjustment, to achieve the adjustment of water supply from zero to the maximum, “how much water, how much water”.

⑤ High power pump motor can be soft started by frequency converter, no impact on the power grid and pipe network, greatly extend the service life of the pump, motor, pipe network and other control equipment.

⑥ Multiple pumps can run alternately, balancing the average working time of each pump, to avoid the corrosion of the pump.

The system operation noise is small, the pressure is stable.

The equipment comprehensive protection function is complete, usually short circuit, overcurrent, overload, water shortage protection and so on. If the user requires other special functions, such as protection functions: overvoltage, undervoltage, lack of phase, three-phase imbalance, text operation display or man-machine dialogue function set monitoring in one of the upper computer communication functions, can be reliable operation according to customer requirements.

⑨ Set the manual and automatic control functions to ensure the safe and continuous operation of the device.

⑩ Small size, space saving, convenient installation.

How to use Irrigation frequency conversion control ?

1.One control one (control one water pump)
There is a total of a water pump on site. The PD value fed back by the pressure gauge or transmitter is compared with the set pressure. When the system pressure reaches the set pressure, the frequency will be reduced, sleep, and standby. When the system pressure is lower than the set value or wake up Frequency conversion and frequency under pressure
2.One use one preparation
The two pumps are standby pumps for each other, and can work alternately according to the set procedure, and only one pump works.
3.One control two (pressure assist) (control two pumps)
A total of two pumps refers to a total of two pumps on site, one works online, and two pumps can work online at the same time. For example, if the pressure of the No. 1 pump is insufficient for a period of time, it will automatically start the No. 2 pump to assist in boosting.
4.It can be customized with rich combination functions such as one control two, one control three, one control four, one control five, etc., as well as power frequency conversion and constant pressure water supply.
