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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be positive that the water dropped at the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to entry floor water from wells and ensure a dependable and cost-effective water provide. The farm’s proprietor commissioned an appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for a number of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be filled with water by a total of six underground nicely pumps in a single day, when the energy prices have been low. A transport pump is used to switch water from the lower reservoir to the higher one. The peak difference permits the sprinkler system to be operated using gravity alone through the day, making it notably environment friendly. The livestock and the dairy can also take their water provide from this irrigation system. The key requirements of the project had been price effectivity and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be certain that the water dropped at the floor is transferred on to the upper tank. The CP models function a PID controller with feedback 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 continually monitoring the flow. If the borehole degree falls below a minimal predetermined by the consumer, the PLC control switches to the next the borehole and prevents the pumps from being damaged.
The system has various Delta DVP collection 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 degree in the prime reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler set up. เกจ์วัดแรงดันลม -machine interfaces (HMI) from the DOP-100 collection are used to display all of the processes within the system and show system data and warning indicators on a 7 or 15-in contact screen. In-house software also allows the time configuration and vitality prices to be monitored remotely. Users can also monitor the entire course of by way of the DOP-100 VNC server.
The system is now working with none issues and provides both livestock and crops with adequate water, even in periods of low rainfall.
