A pumping station powered by Delta CP2000 frequency drives is delivering efficient 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 well pumps and be certain that the water brought to the surface is transferred on to the higher 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 proprietor commissioned an acceptable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following เกจวัดแรงดันน้ำ -depth planning and consultation process, Pienaar Elektries opted for a quantity of automation products 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 overnight, 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 notably environment friendly. The farm animals and the dairy also can take their water provide from this irrigation system. The key requirements of the project have been price effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and ensure that the water dropped at the surface is transferred on to the upper tank. The CP fashions characteristic a PID controller with feedback that allows the water stage in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the totally different pumps and frequently monitoring the move. If the borehole stage falls beneath a minimal predetermined by the consumer, the PLC control switches to the next the borehole and prevents the pumps from being broken.
The system has numerous Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water degree above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level within the high reservoir and the animal watering stations, whereas an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all the processes in the system and show system info and warning indicators on a 7 or 15-in touch display screen. In- เกจวัดแรงดันราคา permits the time configuration and vitality prices to be monitored remotely. Users can also monitor the complete process via the DOP-100 VNC server.
The system is now working with none points and provides each livestock and crops with adequate water, even during periods of low rainfall.
