Delta delivers efficient 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 space experiencing irregular and ever lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water brought to the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to access floor water from wells and guarantee a dependable and cost-effective water supply. เกจแรงดัน ’s owner commissioned an appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for a quantity of automation products from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be filled with water by a total of six underground well pumps overnight, when the power costs were low. A transport pump is used to switch water from the lower reservoir to the higher one. The peak distinction permits the sprinkler system to be operated utilizing gravity alone during the day, making it significantly efficient. The cattle and the dairy also can take their water supply from this irrigation system. The key requirements of the venture have been value effectivity and low energy 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 fashions characteristic 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 move. If the borehole stage falls below a minimal predetermined by the user, the PLC management switches to the next the borehole and prevents the pumps from being broken.
The system has varied Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water degree above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water degree within the prime reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to display all of the processes within the system and show system information and warning indicators on a 7 or 15-in touch display screen. In-house software program also permits the time configuration and energy prices to be monitored remotely. Users also can monitor the whole course of via the DOP-100 VNC server.
The system is now working without any issues and supplies both livestock and crops with adequate water, even during times of low rainfall.
