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 space experiencing irregular and ever lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be sure that the water dropped at the surface is transferred on to the higher tank.
The dairy farm wanted a pump system to access floor water from wells and ensure a dependable and cost-effective water supply. The farm’s proprietor commissioned an acceptable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following weksler ea14 -depth planning and consultation process, Pienaar Elektries opted for several automation products from Delta.
The planned irrigation system comprised two reservoirs at completely different heights, to be full of water by a complete of six underground well pumps in a single day, when the energy prices were low. A transport pump is used to switch water from the lower reservoir to the upper one. The top distinction allows the sprinkler system to be operated using gravity alone during the day, making it significantly efficient. The farm animals and the dairy also can take their water supply from this irrigation system. The key requirements of the challenge had been price efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water delivered to the floor is transferred on to the upper tank. The CP fashions feature a PID controller with feedback that allows the water level within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the totally different pumps and continually monitoring the move. If the borehole stage falls under a minimum predetermined by the person, the PLC management switches to the subsequent the borehole and prevents the pumps from being damaged.
The system has various Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water stage in the top reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all the processes within the system and present system information and warning indicators on a 7 or 15-in touch display screen. In-house software additionally allows the time configuration and power costs to be monitored remotely. Users also can monitor the whole process via the DOP-100 VNC server.
The system is now working with none points and supplies each livestock and crops with enough water, even during periods of low rainfall.
