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 decreasing rainfall.
pressure gauge octa -energy Delta CP2000 frequency drives drive the six underground well 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 ground water from wells and guarantee a reliable and cost-effective water supply. The farm’s owner commissioned an appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for a quantity of automation products from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be full of water by a total of six underground properly pumps in a single day, when the energy prices had been low. A transport pump is used to switch water from the decrease reservoir to the higher one. The peak difference allows the sprinkler system to be operated using gravity alone during the day, making it particularly efficient. The farm animals and the dairy also can take their water supply from this irrigation system. pressure gauge of the project have been value efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make sure that the water brought to the surface is transferred on to the upper tank. The CP models characteristic a PID controller with feedback that permits the water level within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and continually monitoring the flow. If the borehole stage falls under a minimum predetermined by the consumer, the PLC management switches to the subsequent the borehole and prevents the pumps from being broken.
The system has numerous Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water degree in the top reservoir and the animal watering stations, whereas an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all of the processes within the system and present system data and warning indicators on a 7 or 15-in touch display screen. In-house software additionally allows the time configuration and energy costs to be monitored remotely. Users also can monitor the complete process via the DOP-100 VNC server.
The system is now working with none points and provides both livestock and crops with enough water, even during periods of low rainfall.
