เกจวัดแรงดันpressuregauge 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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be positive that the water dropped at the floor is transferred on to the upper tank.
The dairy farm needed a pump system to access ground water from wells and ensure a reliable and cost-effective water provide. The farm’s proprietor commissioned an acceptable 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 planned irrigation system comprised two reservoirs at totally different heights, to be filled with water by a complete of six underground nicely pumps overnight, when the power prices had been low. A transport pump is used to transfer water from the lower reservoir to the higher one. The top difference allows the sprinkler system to be operated utilizing gravity alone during the day, making it notably environment friendly. The cattle and the dairy also can take their water provide from this irrigation system. The key necessities of the project have been price efficiency and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be positive that the water brought to the floor is transferred on to the upper tank. The CP models function a PID controller with suggestions that allows the water level within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the different pumps and continually monitoring the flow. If the borehole level falls below a minimum predetermined by the consumer, the PLC management switches to the subsequent the borehole and prevents the pumps from being broken.
The system has varied Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water degree in the prime reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to display all the processes in the system and present system information and warning indicators on a 7 or 15-in touch display screen. In-house software also permits the time configuration and power prices to be monitored remotely. Users can even monitor the entire course of through the DOP-100 VNC server.
The system is now working with none issues and provides both livestock and crops with adequate water, even during times of low rainfall.
