A 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 decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be certain that the water dropped at the surface is transferred on to the upper tank.
The dairy farm needed a pump system to access floor water from wells and ensure a reliable 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 an in-depth planning and session process, Pienaar Elektries opted for a quantity of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be full of water by a complete of six underground nicely pumps in a single day, when the energy prices have been low. A transport pump is used to transfer water from the lower reservoir to the higher one. The height distinction allows the sprinkler system to be operated using gravity alone in the course of the day, making it notably efficient. The farm animals and the dairy can also take their water supply from this irrigation system. The key necessities of the venture had been price effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water delivered to the floor is transferred on to the higher tank. The CP fashions feature a PID controller with suggestions that allows the water level in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the different pumps and continually monitoring the circulate. If the borehole degree falls below a minimum predetermined by the person, the PLC control switches to the next the borehole and prevents the pumps from being broken.
เกจวัดแรงดันอาร์กอน 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 value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water stage in 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 sequence are used to show all of the processes in the system and show system info and warning indicators on a 7 or 15-in touch display. In-house software additionally permits the time configuration and vitality 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 without any points and provides each livestock and crops with adequate water, even during periods of low rainfall.
