Delta delivers environment friendly 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 area experiencing irregular and ever decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water dropped at the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to access ground water from wells and ensure a reliable and cost-effective water provide. The farm’s owner commissioned an appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following pressure gauge หน้าปัด 2 นิ้ว -depth planning and consultation process, Pienaar Elektries opted for several automation products from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be crammed with water by a complete of six underground nicely pumps overnight, when the power costs have been low. A transport pump is used to switch water from the decrease reservoir to the higher one. The top distinction allows the sprinkler system to be operated using gravity alone through the day, making it notably efficient. The farm animals and the dairy can also take their water supply from this irrigation system. The key necessities of the challenge had been price efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make positive that the water delivered to the surface is transferred on to the upper tank. The CP fashions feature a PID controller with suggestions 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 frequently monitoring the move. If the borehole stage falls below a minimal predetermined by the user, the PLC control switches to the following the borehole and prevents the pumps from being broken.
The system has numerous Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level within the high reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all of the processes within the system and show system data and warning indicators on a 7 or 15-in touch screen. In-house software program also allows the time configuration and vitality costs to be monitored remotely. Users can even monitor the entire process via 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.
