Delta delivers environment friendly irrigation to South African farmers

A pumping station powered by Delta CP2000 frequency drives is delivering efficient irrigation to a dairy farm in South Africa in an area experiencing irregular and ever reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water dropped at the surface is transferred on to the upper tank.
The dairy farm needed a pump system to access floor water from wells and guarantee a dependable and cost-effective water provide. The farm’s owner commissioned an appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following digital pressure gauge -depth planning and session process, Pienaar Elektries opted for a quantity of automation products from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be full of water by a total of six underground properly pumps in a single day, when the vitality costs were low. A transport pump is used to transfer water from the lower reservoir to the upper one. The peak distinction allows the sprinkler system to be operated using gravity alone through the day, making it notably environment friendly. The livestock and the dairy can also take their water supply from this irrigation system. The key requirements of the project had been price effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water brought to the surface is transferred on to the higher tank. The CP fashions feature a PID controller with suggestions that permits the water stage within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the completely different pumps and regularly monitoring the flow. If the borehole level falls below a minimum predetermined by the person, the PLC management switches to the next the borehole and prevents the pumps from being broken.
The system has numerous Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. ไดอะแฟรม within the high reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all the processes in the system and present system data and warning indicators on a 7 or 15-in touch screen. In-house software also allows the time configuration and power costs to be monitored remotely. Users can also monitor the complete process through the DOP-100 VNC server.
The system is now working with none issues and supplies both livestock and crops with enough water, even in periods of low rainfall.
