Delta delivers efficient irrigation to South African farmers

pressure gauge วัด แรง ดัน 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 reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be sure that the water dropped at the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to access ground water from wells and ensure a dependable and cost-effective water supply. The farm’s owner commissioned a suitable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation process, Pienaar Elektries opted for several automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at completely different heights, to be crammed with water by a total of six underground nicely pumps in a single day, when the vitality costs were low. A transport pump is used to switch water from the decrease reservoir to the upper one. The height distinction permits the sprinkler system to be operated using gravity alone in the course of the day, making it significantly environment friendly. The cattle and the dairy also can take their water supply from this irrigation system. The key requirements of the venture were value effectivity and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water delivered to the surface is transferred on to the upper tank. The CP fashions characteristic a PID controller with feedback that allows the water stage in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and regularly monitoring the move. If the borehole degree falls beneath a minimum predetermined by the consumer, the PLC control switches to the subsequent the borehole and prevents the pumps from being damaged.
The system has numerous Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water degree above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water stage within the top reservoir and the animal watering stations, whereas an additional DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all the processes in the system and present system info and warning indicators on a 7 or 15-in touch display screen. In-house software program also permits the time configuration and energy costs to be monitored remotely. Users can even monitor the entire course of through the DOP-100 VNC server.
The system is now working with none issues and supplies each livestock and crops with adequate water, even during times of low rainfall.
