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 make sure that the water brought to the surface is transferred on to the higher tank.
The dairy farm needed 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 course of, Pienaar Elektries opted for several automation products from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be crammed with water by a total of six underground well pumps overnight, when the vitality prices were low. A transport pump is used to transfer water from the decrease reservoir to the upper one. The peak distinction allows the sprinkler system to be operated using gravity alone during the day, making it notably efficient. The farm animals and the dairy can even take their water supply from this irrigation system. The key necessities of the challenge were price effectivity and low energy consumption.

This is finished by alternating between the completely different pumps and frequently monitoring the circulate. If the borehole level falls under a minimum predetermined by the user, the PLC control switches to the next the borehole and prevents the pumps from being broken.
The system has varied Delta DVP series 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. One DVP12SE PLC monitors the water degree in the high reservoir and the animal watering stations, whereas an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all of the processes in the system and present system info and warning indicators on a 7 or 15-in contact display. In-house software additionally allows the time configuration and vitality costs to be monitored remotely. Users also can monitor the entire process via the DOP-100 VNC server.
The system is now working without any issues and supplies both livestock and crops with enough water, even during periods of low rainfall.
