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 be sure that the water dropped at the surface is transferred on to the higher tank.
The dairy farm needed a pump system to entry ground water from wells and guarantee a dependable and cost-effective water supply. The farm’s proprietor commissioned an appropriate system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following ที่วัดแรงดันน้ำ -depth planning and session course of, Pienaar Elektries opted for a number of automation products 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 upper one. The top difference allows the sprinkler system to be operated utilizing gravity alone through the day, making it notably efficient. The farm animals and the dairy can even take their water provide from this irrigation system. The key necessities of the venture were 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 brought to the surface is transferred on to the upper tank. The CP fashions function a PID controller with suggestions that permits 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 move. If the borehole degree falls beneath a minimum predetermined by the user, the PLC control switches to the next the borehole and prevents the pumps from being broken.
The system has numerous Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water stage in the prime reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all the processes within the system and show system information and warning indicators on a 7 or 15-in contact display. In-house software also permits the time configuration and power 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 sufficient water, even in periods of low rainfall.
