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 reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water dropped at the surface is transferred on to the higher tank.
The dairy farm needed a pump system to entry floor water from wells and guarantee a reliable and cost-effective water provide. The farm’s owner commissioned an acceptable 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 several automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be crammed with water by a complete of six underground well pumps overnight, when the energy costs were low. A transport pump is used to transfer water from the lower reservoir to the higher one. The peak difference allows the sprinkler system to be operated utilizing 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 venture had been price efficiency and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water dropped at the surface is transferred on to the upper tank. The CP models function a PID controller with feedback that allows the water degree within the tanks and boreholes to be monitored and corrected. This is done by alternating between the totally different pumps and frequently monitoring the flow. If the borehole level falls under a minimum predetermined by the consumer, the PLC control switches to the next the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water level above the predetermined worth. Five DVP16SP PLCs regulate the motors. เกจ์อาร์กอนsumo in the prime reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to show all the processes within the system and present system info and warning indicators on a 7 or 15-in touch display. In-house software additionally permits the time configuration and power prices to be monitored remotely. Users can even monitor the whole process via the DOP-100 VNC server.
The system is now working without any issues and supplies both livestock and crops with enough water, even during times of low rainfall.
