Delta delivers efficient irrigation to South African farmers

A 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 reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water delivered to the surface is transferred on to the higher tank.
The dairy farm needed a pump system to access floor water from wells and ensure a dependable and cost-effective water supply. 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 consultation course of, Pienaar Elektries opted for several automation merchandise from Delta.
pressure gauge octa planned irrigation system comprised two reservoirs at different heights, to be full of water by a total of six underground well pumps in a single day, when the power prices had been low. A transport pump is used to switch water from the lower reservoir to the upper one. pressure gauge permits the sprinkler system to be operated using gravity alone through the day, making it significantly efficient. The livestock and the dairy also can take their water supply from this irrigation system. The key requirements of the project have been price efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water dropped at the surface is transferred on to the upper tank. The CP fashions feature a PID controller with suggestions that permits the water level within the tanks and boreholes to be monitored and corrected. This is done by alternating between the totally different pumps and continually monitoring the move. If the borehole stage falls below a minimum predetermined by the user, the PLC control switches to the subsequent the borehole and prevents the pumps from being broken.
ไดอะแฟรม has various Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water degree above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water stage in the high reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all the processes in the system and present system information and warning indicators on a 7 or 15-in touch display. In-house software program additionally allows the time configuration and power costs to be monitored remotely. Users also can monitor the whole process by way of the DOP-100 VNC server.
The system is now working without any issues and provides each livestock and crops with enough water, even in periods of low rainfall.
