Delta delivers environment friendly 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 area experiencing irregular and ever decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make sure that the water brought to the surface is transferred on to the higher tank.
The dairy farm wanted a pump system to entry ground water from wells and ensure a reliable and cost-effective water supply. 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 consultation course of, Pienaar Elektries opted for several automation products from Delta.
The deliberate irrigation system comprised two reservoirs at completely different heights, to be full of water by a complete of six underground properly pumps in a single day, when the power costs have been low. A transport pump is used to transfer water from the lower reservoir to the upper one. The peak distinction permits the sprinkler system to be operated using gravity alone through the day, making it notably environment friendly. The cattle and the dairy can even take their water provide from this irrigation system. The key necessities of the challenge were value efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and ensure that the water delivered to the surface is transferred on to the higher 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 finished by alternating between the completely different pumps and regularly monitoring the flow. If the borehole level falls under a minimal predetermined by the consumer, the PLC control switches to the subsequent 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 maintain the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water degree within the top reservoir and the animal watering stations, whereas an extra 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 in the system and present system info and warning indicators on a 7 or 15-in contact display. In- ไดอะแฟรม ซีล allows the time configuration and vitality prices to be monitored remotely. Users also can monitor the complete course of via the DOP-100 VNC server.
The system is now working without any issues and supplies each livestock and crops with adequate water, even during times of low rainfall.
