A 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 reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make sure that the water dropped at the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to access floor water from wells and ensure a reliable and cost-effective water supply. The farm’s owner commissioned an appropriate system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for several automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be full of water by a total of six underground well pumps in a single day, when the energy costs were low. A transport pump is used to switch water from the lower reservoir to the higher one. The peak difference allows the sprinkler system to be operated utilizing gravity alone in the course of the day, making it particularly environment friendly. The farm animals and the dairy can even take their water provide from this irrigation system. The key requirements of the challenge had been price effectivity and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water dropped at the floor is transferred on to the higher tank. The CP models characteristic a PID controller with suggestions that allows the water stage within the tanks and boreholes to be monitored and corrected. This is done by alternating between the different pumps and regularly monitoring the flow. If the borehole level falls beneath a minimum predetermined by the consumer, the PLC control switches to the subsequent the borehole and prevents the pumps from being broken.
The system has varied Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water degree above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water stage in the top 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 sequence are used to show all the processes within the system and show system data and warning indicators on a 7 or 15-in contact screen. In-house software also permits the time configuration and energy costs to be monitored remotely. เกจวัดแรงดันต่ำ can even monitor the entire process by way of the DOP-100 VNC server.
The system is now working without any issues and provides each livestock and crops with sufficient water, even in periods of low rainfall.
