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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be positive that the water brought to the surface is transferred on to the higher tank.
เกจวัดแรงดันแก๊สco2 needed a pump system to access ground water from wells and guarantee a reliable and cost-effective water supply. The farm’s proprietor commissioned a suitable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for a quantity of automation products from Delta.
The planned irrigation system comprised two reservoirs at completely different heights, to be filled with water by a complete of six underground well pumps in a single day, when the vitality prices were low. A transport pump is used to switch water from the lower reservoir to the upper one. The peak distinction permits the sprinkler system to be operated utilizing gravity alone during the day, making it particularly efficient. The farm animals and the dairy also can take their water supply from this irrigation system. The key necessities of the venture had been price efficiency and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water delivered to the floor is transferred on to the upper tank. The CP fashions feature a PID controller with suggestions that allows the water level within the tanks and boreholes to be monitored and corrected. This is done by alternating between the totally different pumps and frequently monitoring the circulate. If the borehole level falls under a minimum predetermined by the user, the PLC management switches to the next the borehole and prevents the pumps from being broken.
The system has various Delta DVP collection 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 screens the water degree within the top reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 collection are used to show all the processes in the system and present system information and warning indicators on a 7 or 15-in contact screen. In-house software program additionally permits the time configuration and power costs to be monitored remotely. Users can even monitor the complete course of via the DOP-100 VNC server.
The system is now working with none issues and supplies both livestock and crops with enough water, even during times of low rainfall.
