Delta delivers environment friendly irrigation to South African farmers

ส่วนประกอบpressuregauge pumping station powered by Delta CP2000 frequency drives is delivering environment friendly irrigation to a dairy farm in South Africa in an area experiencing irregular and ever lowering 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 entry floor 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 different heights, to be filled with water by a complete of six underground properly pumps in a single day, when the power prices had been low. A transport pump is used to transfer water from the decrease reservoir to the upper one. The top distinction allows the sprinkler system to be operated utilizing gravity alone during the day, making it significantly efficient. The farm animals and the dairy also can take their water provide 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 make sure that the water brought to the floor is transferred on to the upper tank. The CP models 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 completely different pumps and regularly monitoring the circulate. If the borehole level falls below a minimal predetermined by the person, the PLC control switches to the next the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water stage within the high reservoir and the animal watering stations, while a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to show all of the processes within the system and present system information and warning indicators on a 7 or 15-in contact screen. In-house software also permits the time configuration and power costs to be monitored remotely. Users also can monitor the whole process by way of the DOP-100 VNC server.
The system is now working with none issues and supplies each livestock and crops with sufficient water, even in periods of low rainfall.
