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 well pumps and make sure that the water delivered to the floor is transferred on to the upper tank.
The dairy farm needed a pump system to entry ground water from wells and guarantee a reliable 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 session course of, Pienaar Elektries opted for a quantity of automation products from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be full of water by a total of six underground properly 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 higher one. The peak distinction permits the sprinkler system to be operated utilizing gravity alone in the course of the day, making it particularly efficient. The cattle and the dairy also can take their water supply from this irrigation system. The key requirements of the challenge were value effectivity and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water dropped at the floor is transferred on to the upper tank. The CP fashions feature a PID controller with feedback that enables the water degree in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the different pumps and continually monitoring the move. If the borehole stage falls under a minimal predetermined by the person, the PLC management switches to the following the borehole and prevents the pumps from being broken.
ที่วัดแรงดัน has numerous Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water level in the prime reservoir and the animal watering stations, while a further DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to display all the processes within the system and present system data and warning indicators on a 7 or 15-in contact display. In-house software program also permits the time configuration and energy costs to be monitored remotely. Users can even monitor the whole process through the DOP-100 VNC server.
The system is now working without any issues and provides each livestock and crops with sufficient water, even during periods of low rainfall.
