Delta delivers efficient irrigation to South African farmers

A pumping station powered by Delta CP2000 frequency drives is delivering environment friendly 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 positive that the water delivered to the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to access floor water from wells and ensure a dependable and cost-effective water provide. The farm’s owner commissioned a suitable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation process, Pienaar Elektries opted for several automation products from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be full of water by a total of six underground well pumps in a single day, when the power prices have been low. Swipe is used to transfer water from the lower reservoir to the higher one. The peak difference permits the sprinkler system to be operated utilizing gravity alone through the day, making it notably environment friendly. The farm animals and the dairy can also take their water provide from this irrigation system. The key necessities of the project have been price effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make sure that the water dropped at the floor is transferred on to the higher tank. The CP fashions function a PID controller with suggestions that enables the water level in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the different pumps and continually monitoring the flow. If the borehole stage falls under a minimum predetermined by the user, the PLC control switches to the subsequent 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 maintain the water level above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water degree within the prime reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to show all the processes within the system and present system information and warning indicators on a 7 or 15-in contact display. In-house software program also permits the time configuration and energy prices to be monitored remotely. Users can also monitor the whole course of via the DOP-100 VNC server.
The system is now working without any issues and provides each livestock and crops with enough water, even during times of low rainfall.
