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 decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain 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 reliable and cost-effective water supply. The farm’s proprietor commissioned an acceptable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for several automation products from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be crammed with water by a complete of six underground well pumps in a single day, when the energy prices had been 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 in the course of the day, making it notably efficient. The farm animals and the dairy also can take their water supply from this irrigation system. The key requirements of the project were price efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be sure that the water brought to the surface is transferred on to the upper tank. The CP fashions characteristic a PID controller with suggestions that allows the water degree within the tanks and boreholes to be monitored and corrected. This is done by alternating between the different pumps and regularly monitoring the move. If the borehole stage falls under a minimal predetermined by the person, the PLC control switches to the following the borehole and prevents the pumps from being damaged.
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 displays the water stage within the prime reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all of the processes within the system and show system data and warning indicators on a 7 or 15-in touch screen. In-house software also permits the time configuration and power prices to be monitored remotely. Users also can monitor the whole course of by way of the DOP-100 VNC server.
เกจวัดความดันน้ำ is now working with none points and supplies both livestock and crops with sufficient water, even in periods of low rainfall.
