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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly 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 access ground water from wells and guarantee a dependable and cost-effective water provide. The farm’s proprietor commissioned an appropriate system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for a quantity of automation products from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be filled with water by a total of six underground properly pumps overnight, when the power prices were low. A transport pump is used to switch water from the decrease reservoir to the higher one. The height difference allows the sprinkler system to be operated using gravity alone during the day, making it significantly environment friendly. The cattle and the dairy can also take their water supply from this irrigation system. The key necessities of the project have been value effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make positive that the water delivered to the surface is transferred on to the upper tank. The CP fashions feature a PID controller with suggestions that allows the water stage in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the different pumps and frequently monitoring the flow. If เพรสเชอร์เกจไฮดรอลิค falls under a minimum predetermined by the user, the PLC control switches to the following the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water stage in the top reservoir and the animal watering stations, while a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all of the processes in the system and present system information and warning indicators on a 7 or 15-in contact display screen. In-house software program additionally allows the time configuration and energy costs to be monitored remotely. Users can also monitor the whole process by way of the DOP-100 VNC server.
The system is now working with none points and provides both livestock and crops with adequate water, even during times of low rainfall.
