Frugal pumping station powered by Delta CP2000 frequency drives is delivering efficient irrigation to a dairy farm in South Africa in an space experiencing irregular and ever lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and ensure that the water delivered to the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to entry ground water from wells and guarantee a reliable and cost-effective water provide. The farm’s proprietor commissioned a suitable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation process, Pienaar Elektries opted for a number of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be full of water by a complete of six underground well pumps in a single day, when the vitality costs have been low. A transport pump is used to switch water from the lower reservoir to the upper one. The peak difference permits the sprinkler system to be operated utilizing gravity alone in the course of the day, making it particularly environment friendly. The cattle and the dairy can even take their water provide from this irrigation system. The key requirements of the challenge were price effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make sure that the water dropped at the floor is transferred on to the upper tank. The CP fashions function a PID controller with suggestions that enables the water stage within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the different pumps and frequently monitoring the flow. If the borehole degree falls below 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 keep the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water degree 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 series are used to show all of the processes in the system and present system info and warning indicators on a 7 or 15-in contact screen. In-house software program additionally allows the time configuration and power costs 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 with none issues and supplies each livestock and crops with adequate water, even in periods of low rainfall.
