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 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 ground water from wells and ensure a dependable and cost-effective water supply. The farm’s proprietor commissioned an appropriate system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for a quantity of automation products from Delta.
The deliberate irrigation system comprised two reservoirs at completely different heights, to be crammed with water by a complete of six underground well pumps in a single day, when the power costs have been low. A transport pump is used to switch water from the decrease reservoir to the upper one. The peak distinction permits the sprinkler system to be operated using gravity alone in the course of the day, making it particularly efficient. The livestock and the dairy can also take their water provide from this irrigation system. The key necessities of the challenge have been value efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and ensure that the water dropped at the floor is transferred on to the higher tank. The CP fashions function a PID controller with feedback that allows the water degree in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the different pumps and frequently monitoring the circulate. If the borehole level falls below a minimal predetermined by the consumer, the PLC management switches to the subsequent the borehole and prevents the pumps from being broken.
The system has varied Delta DVP sequence programmable logic controllers (PLCs). ตัววัดแรงดันน้ำมัน in boreholes and maintain the water level above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water level in the prime reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all the processes in the system and show system information and warning indicators on a 7 or 15-in touch display. In-house software also allows the time configuration and energy prices to be monitored remotely. Users can even monitor the entire process through the DOP-100 VNC server.
The system is now working without any points and provides each livestock and crops with enough water, even in periods of low rainfall.
