A pumping station powered by Delta CP2000 frequency drives is delivering efficient 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 nicely pumps and ensure that the water delivered to the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to access floor water from wells and guarantee a reliable and cost-effective water provide. 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 several automation products from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be filled with water by a complete of six underground properly pumps overnight, when the energy prices had been low. A transport pump is used to transfer water from the lower reservoir to the higher one. เกจวัดแรงดันน้ําไทวัสดุ permits the sprinkler system to be operated using gravity alone in the course of the day, making it significantly environment friendly. The farm animals and the dairy also can take their water provide from this irrigation system. The key requirements of the challenge have been cost effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water brought to the surface is transferred on to the upper tank. The CP fashions function a PID controller with feedback that enables the water stage within the tanks and boreholes to be monitored and corrected. This is done by alternating between the completely different pumps and continually monitoring the circulate. If the borehole stage falls under a minimum predetermined by the person, the PLC management switches to the following the borehole and prevents the pumps from being damaged.
The system has various Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water degree within the top reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to show all of the processes within the system and show system information and warning indicators on a 7 or 15-in contact display. In- เกจวัดแรงดันแก๊สlpg 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 with none issues and supplies both livestock and crops with sufficient water, even during times of low rainfall.
