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 space experiencing irregular and ever decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be positive that the water dropped at the floor is transferred on to the upper tank.
The dairy farm needed a pump system to access floor water from wells and ensure a dependable and cost-effective water provide. The farm’s proprietor commissioned a suitable system from electrical set up 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 merchandise from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be crammed with water by a complete 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 top difference allows the sprinkler system to be operated utilizing gravity alone during the day, making it notably efficient. The farm animals and the dairy also can take their water provide from this irrigation system. The key requirements of the venture had been price effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be sure that the water dropped at the surface is transferred on to the higher tank. The CP models characteristic a PID controller with suggestions that allows the water level within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the completely different pumps and frequently monitoring the circulate. If the borehole degree falls below a minimal predetermined by the consumer, the PLC management switches to the next the borehole and prevents the pumps from being damaged.
The system has numerous Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water degree above the predetermined worth. ไดอะแฟรม ซีล regulate the motors. One DVP12SE PLC monitors the water level within the prime reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 collection are used to show all of the processes in the system and show system information and warning indicators on a 7 or 15-in touch screen. In-house software also allows the time configuration and power prices to be monitored remotely. Users can also monitor the whole course of through the DOP-100 VNC server.
diaphragm seal is now working with none issues and supplies each livestock and crops with enough water, even during periods of low rainfall.
