Delta delivers environment friendly 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 decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water brought to the surface is transferred on to the higher tank.
The dairy farm needed a pump system to entry floor water from wells and ensure a reliable and cost-effective water supply. The farm’s proprietor commissioned a suitable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for several automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be full of water by a complete of six underground properly pumps overnight, when the power prices have been low. A transport pump is used to switch water from the decrease reservoir to the higher one. The height distinction permits the sprinkler system to be operated utilizing gravity alone in the course of the day, making it notably efficient. The livestock and the dairy also can take their water supply from this irrigation system. The key necessities of the venture have been value effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make sure that the water delivered to the floor is transferred on to the higher tank. The CP fashions characteristic a PID controller with feedback that enables the water degree in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and frequently monitoring the circulate. If the borehole stage falls beneath a minimum predetermined by the user, the PLC management switches to the subsequent the borehole and prevents the pumps from being broken.
The system has various Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water stage in the high reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler installation. pressure gauge ดิจิตอล -machine interfaces (HMI) from the DOP-100 series are used to display all the processes within the system and present system data and warning indicators on a 7 or 15-in contact screen. In-house software additionally permits the time configuration and vitality prices to be monitored remotely. Users also can monitor the whole course of via the DOP-100 VNC server.
The system is now working with none issues and supplies each livestock and crops with adequate water, even during times of low rainfall.
