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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be sure that the water brought to the floor is transferred on to the upper tank.
The dairy farm needed a pump system to entry ground water from wells and guarantee a reliable and cost-effective water supply. The farm’s owner commissioned a suitable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for a number of automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be filled with water by a total of six underground nicely pumps in a single day, when the energy prices have been low. A transport pump is used to switch water from the lower reservoir to the upper one. The peak difference allows the sprinkler system to be operated using gravity alone during the day, making it notably environment friendly. The cattle and the dairy can even take their water provide from this irrigation system. The key necessities of the project had been value efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be positive that the water delivered to the surface is transferred on to the upper tank. The CP fashions feature a PID controller with feedback that permits the water stage in the tanks and boreholes to be monitored and corrected. This is done by alternating between the different pumps and regularly monitoring the circulate. If the borehole stage falls under a minimal predetermined by the user, the PLC control switches to the next the borehole and prevents the pumps from being damaged.
The system has various Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level in the high reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler set up. เกจวัดแรงดันco2 -machine interfaces (HMI) from the DOP-100 collection are used to display all the processes within the system and show system data and warning indicators on a 7 or 15-in contact screen. In-house software program also allows the time configuration and power costs to be monitored remotely. Users also can monitor the complete process by way of the DOP-100 VNC server.
The system is now working without any issues and provides both livestock and crops with enough water, even in periods of low rainfall.
