Delta delivers efficient 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 space experiencing irregular and ever reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make certain that the water brought to the floor 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 proprietor commissioned an acceptable 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 a number of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be crammed with water by a total of six underground nicely pumps in a single day, when the vitality costs have been low. A transport pump is used to transfer water from the decrease reservoir to the higher one. The top difference permits the sprinkler system to be operated utilizing gravity alone during the day, making it significantly environment friendly. The farm animals and the dairy can even take their water provide from this irrigation system. The key requirements of the venture have been cost efficiency and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be positive that the water brought to the surface is transferred on to the upper tank. The CP fashions function a PID controller with feedback that allows the water level in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the totally different pumps and continually monitoring the circulate. If the borehole stage falls beneath a minimum predetermined by the user, the PLC control switches to the subsequent the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. เครื่องมือตรวจวัดความดันเลือดเรียกว่า DVP12SE PLC displays the water degree in the top reservoir and the animal watering stations, while a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all the processes in the system and show system data and warning indicators on a 7 or 15-in contact screen. In-house software program also permits the time configuration and power prices to be monitored remotely. Users can even monitor the entire process by way of the DOP-100 VNC server.
The system is now working without any issues and supplies both livestock and crops with adequate water, even during periods of low rainfall.
