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 area experiencing irregular and ever reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be positive that the water dropped at the floor is transferred on to the higher tank.
The dairy farm wanted a pump system to access ground water from wells and guarantee a reliable and cost-effective water provide. 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 session course of, Pienaar Elektries opted for a number of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at completely different heights, to be filled with water by a total of six underground properly pumps overnight, when the energy costs had been low. A transport pump is used to switch water from the decrease reservoir to the upper one. The height difference allows the sprinkler system to be operated using gravity alone during the day, making it significantly efficient. The farm animals and the dairy can also take their water provide from this irrigation system. The key requirements of the challenge have been price effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make certain that the water brought to the surface is transferred on to the higher tank. เครื่องมือวัดความดัน function a PID controller with feedback that permits the water level within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the different pumps and regularly monitoring the flow. If the borehole stage falls under a minimal predetermined by the consumer, the PLC management switches to the subsequent 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 maintain the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens 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 collection are used to display all of the processes in the system and show 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 can even monitor the complete course of by way of the DOP-100 VNC server.
The system is now working without any issues and supplies each livestock and crops with sufficient water, even during times of low rainfall.
